Fastest Film Grain and Subtitle software

[zcream]

I have a 100 min indie film. AE CS6 has an excellent Film Grain filter, but it take 6 days to render. Thats how slow it is. And adding subtitles is also clunky.

ffmpeg has a noise filter and takes subtitles - takes 11 hours in total.

Using a simple film plate, AE CS6 can do grain and subtitles in a day.

Hitfilm does not do subtitles but does an excellent 35mm film grain in 7 hours.

Is there any option that will do a render from Prores or Cineform to X264 or x265 with added film grain and subtitles in realtime ?

It's impossible to get any meaning from these numbers unless you also let us know the specs of your workstation.

If it's the hardware that is the problem, then no number of software or plugin suggestions will help speed up your renders.
