Controls how media is scaled within the current frame:
Comparing Fit (left), Fill (center) and Stretch (right) methods.
- Fit: media is scaled proportionally to fit inside the frame. When the media does not match the aspect ratio of the video frame, some areas remain empty after scaling (pillarboxing or letterboxing).
- Fill: media is scaled proportionally to fill the entire frame. When the media does not match the aspect ratio of the video frame, portions of the media fall outside the frame and thus are invisible (unless further scaling is applied).
- Stretch: media is scaled non-proportionally to have the same dimensions of the frame. When the media does not match the aspect ratio of the video frame, this results in all geometric features being deformed.
