[FFmpeg-user] Matroska Container, FFV1 Codec and GPU Encoding

[Wilk, Sebastian]

That's the general consensus I was able to find with other companies who have a similar project running.

That's the goal, I am currently working on a pilot that revolves around archiving and supplying the videos to the respective worker/department.

Mkv and FFV1 seems to be one of the best options, due to being licensefree and lossless, as well as reasonably fast.

We do not have a whole lot of Videos (yet), but I have to order our hardware, and I wasn't 100% sure if it was CPU only, and I am sure my superiors woud've liked me dumping money on some graphicscards.

Thanks  for the quick, kind and helpful answers.

I did indeed stumble upon CELLAR, and I am sure this topic will be of greater importance in the future.

Kind regards

Wilk

As far as I know, yes. In the Irish Film Institute, we mostly use FFV1/MKV
as a preservation format for SD tape migrations, and FFV1 is really fast at
encoding and decoding these files via CPU. However, we are also
investigating using FFV1/MKV for 2K/4K RGB film scans, and the speeds
obviously drop quite a bit. GPU acceleration would definitely help a lot.

Did you find the CELLAR mailing list in your travels? I'd recommend signing
up as the process of standardising MKV/FFV1 with IETF is documented here
https://www.ietf.org/mailman/listinfo/cellar - it would possibly be worth
starting a discussion there about GPU encoding/decoding.

Best,

Kieran.
