[FFmpeg-user] ffmpeg prores alpha type metadata tag request

[K manjunath]

Hi
Am using ffmpeg to convert Tiff (rgb + premultiplied alpha) image sequence
to prores 4444 xq mov.
When i import it in after effects, it imports as straight alpha by default.
It's not guessing correct.

Tried adding metadata but nothing works.

I shud manually set to premultiplied.

How to fix this?

Can someone please help me with this?

thanks
