Use FFmpeg to generate a movie with alpha channel from separate video and fill movies ?
25 octobre 2017, par jeffpattI have two movies : input_v.mp4 and input_k.mp4. input_v is the video fill, input_k is a black and white matte for keying.
I want to use FFmpeg to create output.mov in the Avid DNXHD codec, with input_v as the fill (RGB) video and the alpha (A) built from the luma values of input_k.
Is this possible ?

FFMPEG Encode .avi/.mov with alpha channel to .3g2 (with alpha kept)
20 septembre 2017, par kangaraooI’d like to convert my 32bits videos (either .avi or .mov) RGB+A, to .3g2 format with FFMPEG, and keep the alpha channel.
It should be something like that
ffmpeg -i C:\Users\naldo\Desktop\test.avi -vcodec libx264 -acodec libfaac -ab 48k -ar 22050 -ac 2 C:\Users\naldo\Desktop\test.alpha.3g2
but it’s not working.
Any ideas ?
Thank you !
