Checklist for Smooth Video Playback
General
Creating smooth video playback is a challenging task, where many factors interact. Video is a data flaw and every component must be able to match the current stream and do its task.

The footage itself is important, too. You cannot smoothly playback a jerky video file. With 'objects' we mean visible objects in the video frames like eg. text letters.
Good:
- Constant object motion
- Slow object motion ( Without blur: max. 1-2 pixels per frame. This is very important for text scrolling. )
- Objects with soft edges ( This is very important for text scrolling. )
- Motion blur
- Downscaling the footage in the output. Movements look smoother when they are minimized.
Bad
- Jerky object movement
- Fast object movement with hard edges and no motion blur
- Upscaling the footage in the output. Movements look jerkier when they are maximized.

The settings are project-specific, so there is not general 'good' or 'bad'. But these settings and media facts have an influence on the video framerate
Check:
- Is the vertical sync active?
- Does the output window have the correct size?
- Does the framerate match the footage framerate?
- Does the framerate match the footage framerate during playback? Check the framerate by moving the mouse to the left of the UI window, the current framerate will be visible in the bottom left of the window
Tip:
- Lower the footage resolution ( Resolution is omportant. File size and clip length does not matter )
- Lower the rendering size (Settings->Output Window->Rendering Size)
