VSE frame rate drop FPS non constant

Hi guys,

I am trying to render a video clip in the video sequence editor but the frame rate is dropping incredibly.

How to fix that? it is not usable at all like that I have the “AV sync” on with little change.

I know that there is a way to put the video sequence in the ram or something.

Thanks for your help.

If your source media is variable frame rate OR its highly compressed, then Blender will have trouble playing it back at fixed frame rate. Best solution is to generate a proxy or just transcode the media to a lightly compressed Blender friendly file.
