はじめに

 

 

Moving images impact our lives heavily nowadays. A changing image speaks much more than a stationary snapshot. Any one who has watched a movie understands how the power of animation can immensely enhance the process of communication. By capturing the moving action faithfully on your computer screen, CamStudio is essentially putting this power right onto your computer desktop.

The video files created by RenderSoft CamStudio are saved in the standard AVI (Audio Video Interleave) format, which is used pervasively in many Windows applications that support video, including MS Office. (You can effectively paste an AVI file into an Office application just like pasting text.)


This ensures maximum compatibility with other software, and you can easily edit the output of CamStudio with a third party video editor.

 

 

RenderSoft CamStudio の使用

 

 

 

 

 

 

 

領域の設定

(メインメニューから choose Regions->Region or Fixed Region or Full Screen)

 

 

 

You should set the Input Region before recording. This allows you to define the area and type of video capture.From the main menu, choose Region

There are 3 types of regions you can choose:

 

 

1) 選択領域

Before recording starts, you can define an arbitrary rectangular region with the mouse. The cursor turns into a pen on cross-hairs, which you use to define a rectangular region on your screen by click-dragging the left mouse button.

 

 

 

2) 固定領域

You can capture a fixed-size rectangular region. A dialog allows you to define the size of the region in pixels.

 

 

 

Before the recording starts, you can move the fixed-size region around the screen to determine where you want the input area to be. To cancel recording, you can click the right mouse button.

 

 

 

Recording will start immediately when the Record Button is clicked. The region of capture is specified by the Left, Top, Width and Height values of the dialog above.

動画の基本

 

When you record a movie using CamStudio, you are actually saving a sequence of bitmaps (known as frames), that, when displayed in rapid succession, exhibit motion.

 

If more frames are recorded per second, the resultant animation will also be smoother. However, this will also cause the file size of the movie to be much larger.

 

In the process of recording, CamStudio allows you to specify two video rates: the input rate and output rate. The input rate tells your computer how many frames to record per second. The output rate tells your computer how fast to play them back. Usually, these two rates are equal, so that the time of playback is equal to the time used in the recording.

 

However, these two rates can also be different. Normally, you do this only if you want to create a time-lapse movie. For example, you can capture a frame once every hour and play the frames back at 20 frames per second.

 

The default value is set at 20 frames per second for the output (playback) rate and 20 frames per second(corresponding to 50 milliseconds sleep time) for the input /capture rate.

 

There is also a third rate: known as the keyframe rate. When a frame is saved in an AVI file, they can either be saved as a full frame, or only as a difference to the previous frame. This keyframe rate specifies how often full frames are written to the AVI file. A high value means you can fast forward/rewind to a particular frame in your movie much faster. But it also means a larger file size.

 

 

 

 

動画オプションの設定

(メインメニューから choose Options->Video Options)

 

 

 

Setting the video options allows you to optimize your video recordings by choosing between the file size, quality and frame rates of your video files.

 

 

Auto Adjust

Use the Auto Adjust settings to set the Key Frame Rate, Capture Rate and Playback Rate automatically through the slider. Shift the slider to the left to increase the frame rate and to the right to reduce file size. If the slider is situated at the right of the Time Lapse indicator, it means you are creating a time-lapse movie.

 

In Time Lapse mode, CamStudio will usually capture a frame only after a long period of time.(Example: after every 30 seconds). However, during playback, the frames will be displayed more quickly. (Example: at 20 frames per second).

 

 

Compressor

The Compressor select-box allows you to select the encoder for your AVI file. An encoder compresses your AVI files to make them smaller in size and cause them to play faster. The default setting is the MS Video 1 compressor.

 

 

Configure

Click this button to configure the parameters of your selected compressor. The parameters for each compressor is different and some settings will cause CamStudio痴 performance to degrade or behave unpredictably. For some compressors, clicking this button will not have any effect.

 

 

 

Quality

The quality setting determines how nicely your picture is saved. A lower value means a lower picture quality but also a smaller file size. Only some compressors use this value.

 

 

Set Key Frames Every

This setting specifies the keyframe rate. When a frame is saved in an AVI file, they can either be saved as a full frame, or only partially as a difference to the previous frame. The keyframe rate specifies how often full frames are written to the AVI file. A high value means you can fast forward/rewind to a particular frame in your movie much faster. But it also means a higher file size.

 

 

Capture Frames Every

This field determines the input frame rate. It dictates how long the CamStudio will 壮leep・after capturing each frame. One millisecond is 1/1000 of a second.

 

If you set this to a large value (for example 1 hour, or 3,600,000 milliseconds), you practically create a time-lapse movie. CamStudio will actually 壮it and watch・for activities on the screen that takes a long time to occur and take a snapshot (say, only once every hour).

 

 

Playback Rate

This field determines the output frame rate. It specifies how many frames are played back per second. A higher value means a smoother playback. Typical values of 20 ・30 frames per seconds are adequate for most purposes.

 

 

カーソルオプションの設定

(メインメニューから choose Options->Cursor Options)

 

 

Setting cursor options can help illustrate the action you are recording by drawing attention to the area where the action happens. The following cursor effects can be selected:

 

Hide Cursor

The cursor will be hidden during screen capture

 

Show Cursor

 

Use Actual Cursor ・The actual shape and position of the cursor will be recorded during screen capture.

 

Use Custom Cursor ・Replace the recorded cursor with a customized one.

 

Use Cursor From File - Replace the recorded cursor with a cursor that is loaded from file.

 

 

Highlight Cursor

When this option is selected, the recorded cursor will have a highlight area around it. This helps in calling attention to the movements of the cursor. You can set the shape, size and color of the highlight area.

 

 

マイクからの音声の記録

(メインメニューから choose Options->Record audio from microphone)

 

You can add a soundtrack to your movie by selecting this option. When enabled, CamStudio will record your voice input from the microphone while it is capturing video.You need a sound card with an attached microphone to use this option.

 

 

マイク音声オプションの設定

(メインメニューから choose Options->Audio Options->Audio Options for Microphone)

 

 

Use this dialog box to set the 記録形式 and 圧縮形式 of your audio.

 

記録形式 -- The recording format is the format your soundcard use to record your voice from the microphone. Its main attributes are samples per second (measured in kHz), mono/stereo input, and bits per sample (usually 8 or 16 bit). Larger values for samples per second and bits per sample will result in better recording quality, but at the expense of the movie file size.

 

圧縮形式 -- This is the format that will be saved with your movie file.You can click on the 鼎hoose Compressed Format・button to select another compressed format. After recording your movie, CamStudio will attempt to convert your audio from the recording format to the compressed one.

 

Your choices for the compressed format are determined by the recording format. If you change your recording format, the compressed format will also change automatically.

 

Interleave Video and Audio ・ Interleave your audio and video for smoother playback on a slow device such as CD-ROM. This will also allow better synchronization of your video and sound content. The interleave factor determines the amount of interleaving in your movie. Normally, this value is specified in number of frames. A value of 1 frame will mean full interleave. Larger values will mean less interleaving.

 

You can also specify the Interleave factor in milliseconds. If you choose to Interleave a movie every 100ms for a movie with a capture rate of 200 frames per second (Capture Frames Every 5 milliseconds), the Interleave factor will be equivalent to Interleave every 20 frames.

 

 

 

Volume - Use this to adjust the input volume of your microphone if your recorded audio is barely audible. If CamStudio is unable to locate your volume control, you will need to adjust the volume manually through Start : Programs : Accessories: Entertainment : Volume Control.

 

 

Please note that some configurations of the Recording and Compressed format will result in the audio recording becoming choppy or inaudible.

 

Some sound card disallows your system to record while another application is playing sound. In this case CamStudio will issue an error when you attempt to record with the 迭ecord Audio・option being enabled.

 

 

Use system method for audio recording

If you set this checkbox, CamStudio will use certain system commands (MCI commands) to perform the recording of audio from your microphone. This method is more stable and may give better sound quality in some systems.

 

If you experience low audio quality when recording from CamStudio, but managed to obtain high quality recordings from your system's Sound Recorder, you may want to consider setting this option.

 

Important

 

 

 

 

 

スピーカーからの音声の録音

(メインメニューから choose Options->Record audio from speakers)

 

 

 

By selecting this option, CamStudio will record the output from your speakers while it is capturing video. This is ideal for recording a gaming session or a movie stream. You will need a sound card with speakers attached to use this option.

 

Please note that not all soundcards support this function. (Most modern and branded soundcards usually allows you to record from your speakers)

 

 

 

Setting Audio Options for Speakers

(メインメニューから choose Options->Audio Options->Audio Options for Speakers)

 

 

Most of the time, you only need to adjust the Playback Volume and Recording Volume.

 

 

Playback Volume

The Playback Volume controls the volume of your speakers. The sound signals going to your speakers and can originate from a variety of sources. Examples include sound from CD, Microphone, MIDI playback and Wave playback.

 

Recording Volume

The Recording Volume controls the volume of the recording line.

 

Important: For a good quality recording, it is important that both the Playback Volume and Recording Volume are not set too high.

 

 

Recording Line Configuration

In order for CamStudio to record sound from your speakers, it has to search your soundcard for the appropriate line to use. Failure to find the line simply means that CamStudio is unable to record from your speakers. Some soundcards do not support this capability.

 

The searching is usually done automatically when you click (Options > Record Audio > Record from speakers). However, if that does not work, you will have to use one of the two methods provided by CamStudio below to carry out additional searching.

 

By clicking the Automatic Search button, CamStudio will play a few tones and attempt to automatically detect the line.

 

If you select the Manual Search button, CamStudio will ask you a few questions on whether you have heard a tone when a particular line is used. You will need to turn on your speakers and listen carefully.

 

 

Note:

 

 

 

 

 

 

 

Soundcard Device

For most users, the Soundcard Device will already be pointing correctly at your soundcard. However, if it isn稚 or if your system has more than one soundcard, you will need to set it to the correct one.

 

If the soundcard device is changed, the recording line will no longer be valid and you will need to perform a manual/automatic search for the line

 

 

 

 

 

自動追随を有効

(メインメニューから choose Options->Enable Autopan)

 

If this option is selected, the capture area will follow the cursor to wherever it goes during recording. This has the effect of making the screen capture to occur at the region with the most action.

 

 

 

自動追随速度

(メインメニューから choose Options->Autopan Speed)

 

 

Use this to control the maximum speed at which the capture area follows the mouse. The value is measured in screen pixels.

 

 

 

 

プログラムオプション

(メインメニューから choose Options->Program Options)

 

Use the program options to customize the way the program behave when it starts/stops recording. A tick beside the menu items indicates that option is enabled.

 

* Minimize program on start recording

* Hide flashing rectangle during recording

* Save Settings on Exit

* Capture translucent/layered windows

Save Settings on Exit

The Save Settings on Exit option allows you to save the program settings when you exit. These settings will be loaded the next time you launch CamStudio.

 

If you run CamStudio and find that it does not work as well as in previous sessions, most likely your saved settings is not tuned very well or is corrupted. You may want to reset your settings by turning off the Save Settings on Exit option, exit CamStudio, and launch CamStudio again.

 

 

Minimizing CamStudio

CamStudio is minimized to the system tray instead of the taskbar. To restore CamStudio, double click its icon in the system tray.

 

 

Play AVI file when recording stops

In here, you can choose to

 

 

Capture translucent/layered windows

In Windows 2000 or XP, there are certain windows that are translucent/layered and cannot be captured without turning this option on. An example is the Office Assistant in Office 2000.

 

 

Temporary directory for recording

CamStudio creates temporary files while it is performing recording. These temporary files can become very large and crash your system if your system ran out of disk space.

 

You can set the directory for placing your temporary files by selecting one of these:

 

 

If you are using the User Specified Directory, you should always choose a directory that resides in the drive with the largest free space.

 

 

Recording Thread Priority

Some programs, when set as the active window, use the system resources so heavily that they cause CamStudio to be unusable. The frame rate in these cases drop to 0 - 5 frames per second (even if only a small region is being captured). Examples include some DirectX games or CPU intensive simulations.

 

To improve the performance of CamStudio at the expense of these programs, you can set the recording priority of CamStudio to Highest or Time Critical. However, doing this may also affect the performance of your whole system (For example, Windows may not respond to some mouse clicks on your Desktop). Therefore, for most cases, this option is best left at Normal.

 

 

Name of AVI

With auto-naming, you can now avoid giving a name to every AVI you record.The name of the file will have the following format 1422003_1520_26.avi and is saved in CamStudio痴 installed directory.

 

The name is formed using the system痴 date and time of the recording.

1422003_1520_26.avi means the file is saved on 14th of February, 2003, 3.20 p.m (1520), at the 26th second.

動画注記

(メインメニューから choose Tools->Video Annotations)

 

This feature requires a webcam to be installed on your system. The Video Annotations window is essentially a webcam window. By placing a webcam window on your desktop, you can record its content along with other screen content when the webcam window is inside your recording region.

 

 

 

The Video Annotation window does not only stream video content to your desktop. You can also add a text caption, make a cutout region, or set transparency values (Win 2000 / XP only) to the video annotation just like you did for screen annotations. To do so, right-click on the webcam window to display a menu like this

 

 

 

The Edit Text, Edit Image and Edit Transparency commands have already been covered in the section on Screen Annotations and will not be explained here.

 

Refresh Rate

 

 

The refresh rate indicates the number of times (frames) CamStudio will attempt to capture an image from your webcam and display it on your screen. The actual rate will usually be much lesser, especially for large sized images.

 

Important :

 

ｷ        Setting a high refresh rate will degrade the recordings of CamStudio considerably. This is especially true if transparency is turned on. It has been observed that some dialog boxes will not appear when they are selected when the Video Annotation window is shown. To stop the blocking of these dialog boxes, you will need to close the Video Annotation window first.

 

ｷ        The slowdown in the recording rate will be observed even if the Video Annotations window is not inside the recording region. In fact, the presence of the Video Annotations window will even affect the performance of other programs in your system. Therefore, it is highly advised that you close the Video Annotations window when it is not needed.

 

ｷ        Sometimes, especially on slower systems, the video of the webcam images will appear to be slightly behind the audio track on playback. This is because the acquisition of an image and its display on the screen is quite demanding on your system resources. The computer will take some time to process the acquired image before showing it on the screen.This latency problem can usually be resolved by

 

1)     Choosing a smaller dimension for your video format or

2)     Shifting the video track slightly to align it with the audio track. More information can be found in the section Audio and Video Synchronization below.

 

 

Video Source

 

You can use the video source dialog to select your webcam or video source for the video annotation. You can also set the brightness, contrast, gain, exposure and other settings related to your webcam video.

 

動画形式

 

The video format dialog is used for selecting the dimensions of your webcam or video source image. You can also set the pixel depth and compression (e.g RGB24, RGB32) of your video.

 

注意: You are advised to choose a small dimension (e.g 160 x 120) for the video format, as a large sized format will slow down your system significantly.

 

The video source and video format dialog boxes will vary on different systems. Its implementation will very much depend on the vendor of your webcam.

 

 

音声と動画を同期

(メインメニューから choose Options>Audio Options->Audio and Video Synchronization)

 

 

If the video and audio track of your recording is not in phase during playback, you can try to shift a stream slightly to make them back in sync. This may happen if you are recording the output of a webcam.The amount of shift is measured in milliseconds, and the appropriate value for the shift can usually be determined after a few trail recordings with different time shift values.

 

注意 : The dialog above only handles the case when the audio streams appear to go before the video.

 

 

 

記録について、質とパフォーマンスについての注意事項

 

  CamStudio creates a movie by sampling the screen on fixed-time intervals. If this sampling frequency is too slow, it may not be able to pick up some cursor movements if the mouse moves too fast. The result of this will be that the cursor will appear to jump, become jerky or even cannot be seen in the recorded movie. It is thus advisable to slow down your mouse movements during recording.

 

  This sampling problem can also happen when you are recording a fast animation. If CamStudio cannot record much faster than the changes in the animation, CamStudio will miss out on some important data and the playback will not be smooth.

 

 

 

フレームレート

 

The speed of your computer will directly affect the performance of CamStudio. A slow CPU will unquestionably mean slower frame rates. For the best performance, use the fastest computer available for recording.

 

Apart from CPU speed, the following factors will also affect the performance of the recording:

 

 

 

 

 

 

ファイルサイズ

 

An AVI file usually has a very large file size, especially for those lengthy and detailed videos. This is due to the fact that a video file has to pack hundreds and thousands of images into a single file. It is thus very common to have size exceeding one megabyte.

 

To reduce the size of the AVI file, you can do the following:

 

 

 

 

 
 
Flash (SWF) ファイルの生成:

CamStudio では、二つの方法で Flash ファイルを作成できます。

 

1) Flash に直接記録

To record directly to Flash, simply click the button to toggle the recording mode to .

 

After that you may proceed in the same way as you record an AVI file.

 

There are a few options that you can adjust prior to recording to Flash.These are accessed with the Options :: Record to Flash commands in the menu.

 

 

  The Preview SWF File upon completion instructs CamStudio to display your Flash movie in a HTML file when the production is completed.

 

  The process of recording to SWF actually involves multiple steps. CamStudio in fact record your screen activity to an intermediate AVI file first, before converting it to a Flash (SWF) file. The Delete the intermediate AVI file upon completion setting thus instructs CamStudio to delete the intermediate AVI file when the conversion is completed. You may want to preserve the AVI file just in case you値l like to edit it in an AVI editor, but that will take up plenty of space on your hard disk, as the format of the AVI is saved with minimal compression settings.

 

  The production an SWF file is affected by many parameters in the SWF Producer. These parameters are, by default, hidden from users, but may be revealed if you turn on the Display conversion options before generating SWF setting. For a full description of these parameters, please refer to the section on ・a href="helpProducer.htm#Parameters">Conversion Parameters・in the SWF Producer help file.

 

 

2) 既存の AVI ファイルを SWF Producer で Flash に変換

 

The CamStudio distribution package includes a module known as the SWF Producer that is able to convert an AVI file to SWF. This is actually a separate program that can function independently of the CamStudio Screen Recorder.

 

  The SWF Producer is launched by selecting Tools :: SWF Producer from the menu.

 

 

You can also double click the Producer.exe file in CamStudio痴 installed directory to launch it.

 

While the SWF Producer works best with the AVI files recorded with CamStudio, it is in fact capable of converting most AVI files created by third party products. Normally, Flash files generated by the SWF Producer results in a much smaller file than the original AVI.For a full description of the usage of the SWF Producer, please refer to the topic on Standalone mode in the SWF Producer help file.
