SVT-VP9 Framerate??

I've been playing with some compiled binaries my friend managed to find for me. But I'm having trouble with setting the proper FPS.

if I specify -fps-num 24000 -fps-denom 1001 it will output a file with 23.98 fps which ffmpeg does not like.

If I just tell it 24, ffmpeg will take it, but then the audio from the original source will be off by 1 second (source clip is 10 minutes, video file comes out to 9m59s)


Is it just not supported at this point, or is this some bug I have to wait for them to fix... Can I rescale the "FPS/duration" of the audio in ffmpeg as a compromise? What is the proper way to go about doing that?

edit:
Maybe a misunderstanding on my part. When I dump the input mkv file to YUV with ffmpeg it seems to want to assign it the 23.98 fps at that point.
I can't seem to get it to play nice in that regard

How does ffmpeg not like it? Ffmpeg has had excellent support for fractional framerates for as long as I can remember.

Because you sped up the fps by 0.1%, and the video isn't. Any audio tool like Audition or Audacity can also resample your audio 0.1% faster; another way to fix your problem.

Did you specify the fps of the YUV? YUV doesn't have any metadata, so you need to manually specify fps along with a whole lot of other stuff. I much prefer .y4m for this, which is a yuv file but with metadata headers.

Yes, I always specified the FPS when importing the YUV. I was unaware it would take Y4M, so I may try going that route.
I think at some point I even tried throwing a framerate declaration on the YUV file during creation as well.

basically if I create a YUV file it'll come out as 23.98 fps. SVT will encode it as 23.98fps if I specify framerate as 24000/1001 IIRC

At that point I cannot get the IVF file muxed into a webm because ffmpeg would throw an error IIRC about invalid framerate.
I tried using mkvtoolnix (through the provided GUI) and it would always error out as well but not really give info on why it failed. I have only been able to successfully mux a file encoded by SVT when the framerate was a solid 23 or 24 fps.

it's my day off, so I will prepare and do some more tests and post my workflow here so i can provide a better and more accurate picture.

I produced a Y4M with ffmpeg 4.1.3

The original source file chain was an MKV dump of one of my Lord of The Rings discs, which I cut into a 10 minute chunk of video (-ss -to )for testing purposes with various encoding schemes.

I further cut that chunk into a 1 minute chunk (-to) when I realized how huge a 10 minute YUV file was going to be.

Code:
ffmpeg -i LOTR-Test.mkv -an -to 00:01:00 "D:\SVT-VP9\LOTR-Test.y4m

----
Input #0, yuv4mpegpipe, from 'LOTR-Test.y4m':

Then I fed this file through SvtVp9EncApp.exe version 0.1.0
Code:
PS D:\SVT-VP9> ./SvtVp9EncApp.exe -i LOTR-Test.y4m -w 1920 -h 1080 -fps-num 24000 -fps-denom 1001 -b LOTR-Test.ivf

LOTR-Test.ivf: Invalid data found when processing input
PS D:\SVT-VP9>
At this point I am going to argue that I have no idea what I am doing wrong.

If I make changes to specify the framerate as either a straight 23 or 24 (i.e if I try -fps 23.98 SVT will round it down to 23fps) SVT will encode it and the file will mux fine into a webm.

Also of interesting note, on the 24000/1001 attempt if I try to open that file with mediainfo, it complaints about a floating point error. The Y4M opens fine, and a 23 or 24 fps IVF file will open fine.

just for kicks If I feed the encoder the y4m and only declare the width and height, it will encode it as 60fps but reports invalid framerate. when trying to open with ffmpeg - mediainfo will at least open it but reports an fps of 0.

So again, refering my very first attempt cited above, I just don't know what I'm doing wrong. Maybe I'm "special".

I know the SVT build is somewhat old but I'm not aware of any major fixes that would account for something like this?

What happens if you don't specify a frame rate at all? It might just pass it forward.

When no framerate is specified it defaults to encoding 60fps and ffmpeg doesn't seem to like those files either. (I think it gives the same invalid framerate response, can't remember exactly)

Can't reproduce with latest svt-av1 (master branch).

Note that the error comes from FFmpeg's ivf demuxer. You should be getting the same error if you just try to demux and decode the file:

Code:
ffmpeg -i LOTR-Test.ivf -c rawvideo -f null -
The error comes from here:
https://github.com/FFmpeg/FFmpeg/blo...fdec.c#L54-L63

So, either your file has an invalid ivf header, or the time_base info in the header is invalid.

My guess is your very old encoder binary (version 0.1) has an ivf mux bug that was fixed later.

Interesting. I'll endeavor to try and find a more recent version (compiling stuff for Windows isn't really my area, nor is installing a bunch of tools to do it).
I'll have to go back and look at my linux VM as well, that's an environment I could try and mess around with compiling stuff on I suppose.

Will report back here with my findings eventually.

Actually, forget about that part of my comment. I thought you were testing the AV1 encoder.

I just tested the VP9 one (master branch). The issue you describe exists for me when no -fps-num/-fps-denom are passed. And checking with a hex editor confirms that the file header is invalid (0000 0000 03e8 0000 which corresponds to 0/1000 instead of 60000/1000). The floating point errors you are seeing are caused by division by zero.

However, when passing -fps-num 24000 -fps-denom 1001, I do get valid files. The header is valid (5dc0 0000 03e9 0000 which corresponds to 24000/1001), and the files are playable/mux-able.

It's worth mentioning that I tried many encoding settings, and I'm getting ghosts everywhere every time. So, you're not missing much. And I don't think anyone should bother with this encoder.

Hi, yeah I noticed the 60fps thing as well. I did acquire a more recent compile from a friend and got it up and running on Ubuntu vis WSL. It did seem to fix the issue with 24fps files, although mediainfo being the quirk it is, still tells me its a solid 24 and not film 24 lol.. Audio and Video streams are in sync though.

I haven't looked too much into the quality of the encoder yet, but it certainly has limited uses for now... Definitely needs a 2 pass mode and when using CQ mode it doesn't seem to respect min-qp / max-qp flags.

I recently got myself a Ryzen 7 3700x this past week (my impulse got the better of me, I was trying to save for a R9 3900 or 3950), so I decided to give SVT-VP9 another spin. Was happy to hear about the new AVX2 codepath as well.

I got pretty acceptable qualiy which, off the cuff, I would equate to mid 2000's cableTV in terms of you can see some macroblocking in dark scenes, but anything else you'd probably have to be specifically looking for.
This is all subjective of course, I don't claim to have the best eyes, and I have little practice in spotting encoding errors and other artifacts. The target was 720p with a quality/density (enc-mode) metric of 5... I really wish I could find some in depth comparisons of enc-mode settings to help pick a good middleground between performance and image quality...

Anyway these were the settings I used, encoded with the binaries available from the Pre-Release folder on SVT-VP9's git repo.
Granted this produces a file with some seek-lag because of missing options, I am loathe to post images as they aren't all that useful when judging video overall.

Code:
 .\SvtVp9EncApp -i LOTR-Test.yuv -w 1280 -h 720 -fps-num 24000 -fps-denom 1001 -rc 1 -tbr 1800000 -min-qp 20 -max-qp 25 -enc-mode 5 -b Test.ivf
The following command yields an average of 80fps on a Ryzen 7 3700X boosting to around 3.6Ghz (base frequency), enc-mode 6 gets it to boost to around 3.7 with an average fps of 90. My CPU may be underperforming a little because for noise and heat concerns I have it slightly voltage limited until I can get a Noctua D15 for it.

in both cases it's using maybe 65 - 70% of total CPU power, so you could potentially run two encodings at once for a slightly lower per file FPS, but higher FPS overall. Splitting videos into 2 parts and encoding at once could potentially be a lot faster.

edit: confirmed I can encode two files at once at near the same speed. Pretty nice to be honest. Although if one file were to finish before the other, it does not seem to yield back the CPU resources so the speed on the second file never increases.

Hi!
Are there any ffmpeg builds with SVT-VP9 included available somewhere?
