Support the AV1 codec (and open-source codecs)

PostFri Apr 09, 2021 3:51 pm

All in the title.

I got a video file from someone to edit, I dragged it in Resolve (17.1.1 Windows 10), and only the audio appeared :/ I get them more and more now.

Another file I have to transcode before I can start to work with it.

And for some reason, I can't open VP9 file too now (I had success with that before, I don't know why).

I'm fine by not having this flexibility for the export, but I really want to be able to skip this transcoding process. It's time consuming and disk space consuming if I want to preserve 100% of the original file.

https://en.wikipedia.org/wiki/AV1

AOMedia Video 1 (AV1) is an open, royalty-free video coding format initially designed for video transmissions over the Internet. It was developed as a successor to VP9 by the Alliance for Open Media (AOMedia),[2] a consortium founded in 2015 that includes semiconductor firms, video on demand providers, video content producers, software development companies and web browser vendors. The AV1 bitstream specification includes a reference video codec.[1] In 2018 Facebook conducted testing that approximates real world conditions, the AV1 reference encoder achieved 34%, 46.2% and 50.3% higher data compression than libvpx-vp9, x264 high profile, and x264 main profile respectively.

Like VP9, but unlike H.264/AVC and HEVC, AV1 has a royalty-free licensing model that does not hinder adoption in open-source projects

Resolve does seem to focus more on professional or camera-based codecs. I'm kind of in agreement with that philosophy, so I would vote no here.

There are plenty of consumer editors that can handle 'delivery' formats.

lol again with the imaginary vote.

There is no such thing of a "delivery format". By the same logic, Resolve shouldn't be able to open a h264 video file because everything is already baked in... you know, "ready to go", "delivered", "exported" (whatever you want to call it) by the camera.

I can have this kind of weird logic too. Resolve is free, Sony Vegas Pro is not. Resolve is a "consumer editor", Vegas pro is for... Pro, because it's not free, and there is "Pro" in the name. Therefore Resolve is for "non-pros" and needs to be able to read video encoded with the AV1 codec. Thanks BMD.

Anyway.

We (others) already had this discussion about "professional codecs" (for those who are catching up)

To present a video to a non-video-nerdy customer it seems preferable to use Webm (VP9+Opus). Currently it is the one format that is supported and playable directly e.g. via browser, while not relying on outdated codecs like H.264. At least until AV1 is usable.

You never really provide any rationale or proof to support your views. FFV1 in MKV is used a lot for video archiving purposes.
You can use MKV in stand-alone Fusion if you configure the FFmpeg support that Fusion has.

Resolve already uses FFmpeg for some stuff so that might be a shortcut for MKV support if they don't want to implement it using custom code.


Sorry, there is nothing to vote on here ;) Your "blank vote" is duly noted and put in the trash bin.
Hey, I vote Yes :geek:

TONS of "pros" want to be able to do what the feature request is about. TOOOOONS. You know why? Because nobody in its right mind would say something like : "I don't want to be able to open a particular video file", that's what you're saying.

AGAIN, Let BMD manage their resources. They don't need you to tell them what is important or not especially if the requested feature doesn't break anything, doesn't take away anything, and doesn't change any paradigm, or workflow, or whatever.

Don't worry, they are looking at your feature requests too, the ones you're constantly bumping ;)
There is no competition here.

I know I have no vote, but I vote YES to AV1 support :)

Chrome has just enabled AV1 support for Version 90.0.4430.72, youtube has some videos that already use AV1, there's talk of 30% better compression vs h.265, etc.

Only downside would seem to be an only software encoding solution, so rendering times might take a hit. Would very much like it if Resolve would be ahead of the curve for people looking to maximise their quality options.

Cheers.

I'm curious if Brave (based on Chrome) has it enabled too.. I have to test.

For the encoding part it's not too much of a problem (it would be a good addition anyway), youtube accepts ProRes, Cineform and DNxHR (if someone wants the top quality.... youtube re-encode it anyway.)

The feature request is mostly to be able to open these file encoded with open-source codecs (and containers like MKV, WebM, etc) so we can bypass the transcoding part and concentrate on the edits.
