We rendered a bunch of Clips as PNG-Sequences that we would like to encode as MOV with DXV 3 codec // HQ with alpha. while it works easily by importing into AE then rendering from there, it doesnt if we render via Media Encoder. The benefit of that would be that we can render in the background.
No file thats being produced via AME has an alpha channel. either setting HQ/LO/ALPHA. verified thers no alpha channel in AE and in Arena. doesnt have to do with the premultiplied or straight setting of the clip in arena either, that buttons is simply not there when i play a file from AME.
also tried rendering in 32 bit from AME - no alpha. also tried importing the PNG sequence directly into AME and rendering that - no alpha.
also read the other threads here on the topic, tried all that.
why can AME not produce an alpha channel in DXV3?
any ideas??
