File Format

The Flash output (MPEG-4 or SWF) creates a high quality, low file size video for playback on multiple Web browsers. Select the Flash file format:

MPEG-4 (Recommended): Offers the best compression for both screen recordings and high motion videos.

SWF: Ideal for producing short videos (approximately 15 minutes or less) that do not contain a great deal of motion, such as transitions, Zoom-n-Pan keyframes, or animation.

MP4 Options

Option	Description
Frame rate	The Automatic option preserves the highest frame rate for all clips on the Timeline. To decrease the file size, select a lower frame rate. Decreasing the frame rate to reduce the bandwidth required by the video stream may cause the video to appear choppy during playback.
Bit rate	Drag the Bitrate slider to adjust the data transfer rate (in Kbps). Determines the overall size of the video by setting a maximum Kilobytes per second to use. A lower bitrate produces a smaller file size but may decrease the video quality.

 

SWF Options

Option	Description
Colors	The Automatic option preserves the highest color settings for all clips on the Timeline. To decrease the file size, select a lower color depth. Decreasing the color depth degrades the quality of the produced video.
Frame rate	The Automatic option preserves the highest frame rate for all clips on the Timeline. To decrease the file size, select a lower frame rate. Decreasing the frame rate to reduce the bandwidth required by the video stream may cause the video to appear choppy during playback.
Use JPEG compression and quality slider	JPEG compression loses some image quality. 100% is the highest quality for the compressed video and 10% is the lowest. Higher image quality results in larger file sizes for the produced video.
Compressed SWF (Recommended)	(ExpressShow template only) Compresses the SWF video file. Disable the Compressed SWF option when embedding the produced video into a PDF or PowerPoint presentation.
