SVDesigner

 

 

It is possible to record the CAD view to a video file for purposes such as demonstrating a model. This item opens the Record Video dialog where options for recording the video are specified. Video recording is started once the OK button is clicked in the dialog. To stop recording, select the Record Video menu item again (or press Ctrl + R).

 

Dialog Options

 

File Path:Specifies the path for the video output file. The Browse button may be used to specify the path through a standard file dialog.

 

Quality Level:Specifies the trade-off between file size and video quality, where a higher quality level produces larger files. It is recommended to use values in the middle two thirds of the scale to achieve a reasonable quality and file size.

 

Compression Effort:Specifies the trade-off between time taken to encode the video and video quality, where a higher value is slower to encode. Higher values also tend to produce smaller file sizes.

 

Remarks

 

While recording is underway, the data is written to a temporary file in the specified directory with a ".sviv" extension. This file can reach multiple gigabytes in size for videos lasting minutes; therefore, the path to the output file should reside in a disk with sufficient free space. When recording is stopped, the encoder is launched to convert the SVIV file into the final video file, and the SVIV file is then deleted.

 

Video encoding is an inherently CPU-intensive process that can require a long time to complete. The lower settings for compression effort take approximately 5-10x as long as the length of the recording to complete, while the higher settings take as long as 20-100x the video length. The default setting is a reasonable compromise, but it should be decreased for longer videos or when limited time is available to encode the video.

 

Only the CAD view is captured to video, not including dialogs or other user interface elements.

 

Playback Compatibility

 

The resulting video is encoded as a WebM file using the VP9 open video encoder. Most web browsers can play the file by drag and dropping it into the browser window. Free video players such as VLC can also play the file.
