Its for final output to share later, prores proxy the lowest q one gives me 30 mb for 10 seconds , while h265 gives me 3.9 mb, thats a major difference, but i would like to have something like 8mb h265 for 10 seconds.Its cause i dont want to to export prores and then export again as final edit in other software, just prefere to correct in MLVapp and its done, ill direct stream merge the files in avidemux, so having greater control over quality of export with h.265 would be very useful, other programs dont have such good color correction tools but major factor is encoding twice which takes time and disk space.
