==== Add Video to Slide List ====

This can be done as follows.

  * Select an unconverted video (or videos) from the File List and Right Click on it. Choose "Add Selected Files to Project". You are asked if you want to Optimize the file. Choose "Optimize". The file will be added to the Slide list while the Optimization is carried out in the background. When Optimization is complete the Converted File is shown in the Slide List. (The conversion might take several minutes).
  * Select a Converted Video (or Videos) from the File List and Right Click on it. Choose "Add Selected Files to Project". The converted file is added to the Slide List.
  * Drag an unconverted video (or videos) from the File List into the Slide List. You are asked if you want to Optimize the file. Choose "Optimize". The file will be added to the Slide list while the Optimization is carried out in the background. When Optimization is complete the Converted File is shown in the Slide List. (The conversion might take several minutes).
  * Drag a Converted Video (or Videos) from the File List into the Slide List.

When Video Files are added to the Slide List the Slide Duration is calculated according to the Video Duration and can differ according to the setting of the "Default Options for New Slides" in:

  * Settings/Preferences/Project/Default Options for New Slides/Keep Full Slide Duration.

  * If the option is OFF the Video Clip ends at the beginning of the following transition
  * If the option is ON the Video Clip ends at the end of the following transition

Video Clips can also be added in Objects and Animation via the Movie Icon or the Right Click Menu. In this case all adjustments to the Slide and Video Durations must be made manually.

==== Optimization and File Size ====

Optimized video clips can have larger or smaller file size than the original video clip. It depends on the bitrate of source file. For example digital cameras use high values - about 40 mbit per second for 1080p video. Whereas video editors can suggest 15-25 mbit by default.

Digital cameras have to record video stream in realtime, they have limited battery and slow hardware to compress video. High bitrate compensates these restrictions. In a software encoder we have much more powerful CPU and more time to analyze video stream to more optimally compress video picture.
