Adding Video to the Project

Video can be added to a PTE AV Studio Project in the same way as images can be added.

  • Via the File List
  • By dragging and dropping into the Slide List
  • By adding as an Object in Objects and Animation

Trim Video and Adjust Speed

  • In Objects and Animation / Properties click on Trim and Adjust Speed
  • Use the Trim Video to adjust the length of the Clip by setting any combination of Start Time, End Time, Duration and Speed or dragging the white place mark
  • Press the play button for a preview of the video with sound

In PTE AV Studio 12, we've included a new feature - Trim and Adjust Speed editor for video objects.

As in previous versions, you can adjust the start time, duration, and simple video speed.

Now it's possible to add keyframes on a special timeline to flexibly control video speed. This works similarly to how you use the envelope tool to change audio volume at keypoints in the main window timeline.

You can smoothly slow down video playback, then speed it back up to normal. You can also insert a pause where a video frame stays still for a period of time.

Simply click on the orange line to add points, then drag a point up or down. Adjusting the speed will mute the sound of a video.

By default, speed is set to 100% - original speed.

Setting it to 200% will double the video speed.

Setting it to 0% will stop playback completely. Placing two points with zero speed next to each other creates a pause interval during playback. This is shown in the example below.

Note that a hint for a selected keypoint on the timeline shows two time values: - the original video time - the modified time, which reflects the effect of slowdown or speedup.

You can zoom the timeline in or out using the “+” and “−” buttons on the toolbar, or with Ctrl + mouse wheel.

The “[” and “]” buttons on the toolbar set the Start time and End time respectively to the current position of the time cursor (the vertical red line).

Undo is available via Ctrl + Z for all speed and trim edits.

The “Interpolate frames” option is useful when slowing video down significantly (for example, to 10% of normal speed). Two adjacent video frames are blended using a Dissolve method. This can be useful for creating a special artistic effect. Read more

If you want to delay the start of a video object, the easiest way is to use the Offset parameter in the Properties tab of the Objects and Animations editor, and adjust the Duration (or End time) there. Using keyframes for this is less convenient.

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.
