How do i convert a transparent .mov-file to an mp4 file overlayed on a background-image using FFMPEG [migrated]
5 mars 2013, par ErnieI'm trying to convert a mov file with the following specs :
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'test.mov':

handler_name : Apple Alias Data Handler
timecode : 01:00:00:00I want a background-image with that video on top of it and save it as an mp4-file. In the meantime the video has to be scaled and cropped
I need a solution which can be automated and placed on a server, that is why i tried ffmpegThis is wat have at the moment :
ffmpeg -loop 1 -f image2 -i background.png -r 25 -an -vcodec libx264 -b:v 1500k -vf "movie=test.mov[movie];[movie]scale=max(552\, 420*iw/ih):-1[OUT1]; [OUT1]crop=552:420[OUT2]; [0][OUT2] overlay=0:0 [out]" -s 552x420 -y output.mp4
The problem is, somehow, the transparency is lost, and the background is black, instead of the underlying image. When i try the same ffmpeg command with a transparent FLV as input, it works, but i would like it to work without having to convert al source files first to another format
Any help with this would be greatly appreciated !
