Hi! I'm using adobe premiere to do my video editing with the videos that I had render out from 3D softwares. I need to increase the speed of some clips as the camare movement is to slow. The clips are rendered out in PNG format with alpha channel. I know I can change the speed just by right clicking on the file and change the speed and duration from there but when I change the speed, I no longer have the alpha channel working. Is there any work around or I have to re-render it all over again?
