Overlay video formats: add support for H.265 (HEVC) with transparency in an MOV file?

I know that the overlay function supports using FLV or MOV files (along with PNGs—does the overlay module support PNG animation or just static PNGs?). Since almost nobody supports creating FLVs these days (I tried using VLC to convert to FLV but it defaults to using the H.264 codec, which doesn't support alpha channel/transparency), would you consider supporting MOV files that use H.265/HEVC codec with alpha channel/transparency? Right now in order to do animated lower-third overlays, I have to export them as MOV files using ProRes 4444, which produces *really* huge files—my overlays for a recent project were over 7 GB! If I could save them as HEVC MOVs and use them in ProHD, they'd take up a lot less space! I created some MOVs with a transparent background using HEVC, but ProHD can't see the transparency—all it sees is a black background and so none of the original video comes through.

Hello Kent,
- in the overlay is possible to use PGM only for static graphics.
- we do support MOV format in the ProHD it is from version 6.4. please let me know if you need install file for update
please check the link bellow to see the export parameters for supported mov and other formats

Ďakujem, Vlado! I appreciate the link to the export-parameters document—that is very helpful. I only suggested supporting H.265 with transparency in .MOV files because it creates much smaller files than the ProRes 4444 codec does. But of course I can continue using the ProRes codec, no problem. :-)

Hello Kent,
I will discuss this with our development team to see the possibility to have H.265 decoder for overlay and other files.
and the possibility to add this to the development plan.
all the best,
Vlado
