ffmpeg-quality-metrics reviews and mentions

• VMAF is confusing me
  2 projects | /r/DataHoarder | 29 Jan 2023

  Have you seen ffmpeg-quality-metrics? I went with the docker option. I figured that would keep it simple with ffmpeg versions/whatever.

• VMAF
  1 project | /r/ffmpeg | 9 Dec 2022

  I'm not good at computers, so I love ffmpeg-quality-metrics. I use the docker version because I didn't want to fight with dependencies.

• Encoding tv shows and movies
  1 project | /r/PleX | 27 Nov 2022

  There are even tools that can compare the quality for us, like ffmpeg-quality-metrics can give a VMAF score as used by Netflix for the visual quality difference.

• Should I recompress video I shot with mobile?
  2 projects | /r/DataHoarder | 20 Nov 2022

  You can at least test the quality difference between two encodes with something like ffmpeg-quality-metrics. If it has a high VMAF score and saved a bunch of space for something that doesn't need to be perfect, then I consider it fine.

• did I fail at preserving dvds? mpeg2 vs h264 vs av1

  ffmpeg-quality-metrics is nice for comparing quality between copies. Better than squinting at pixels IMO.

• Movie or scene to test out different bitrates and resolutions
  1 project | /r/DataHoarder | 21 Jun 2022

  If you're re-encoding video then ffmpeg-quality-metrics is a great tool IMO. Can give you a scale from 0-100 of how similar it appears based on SSIM or VMAF. If I get a VMAF in the high 90's, like 95+, then I know the encode is decent and if it saved significant space (if that's the goal?) then it's a keeper.

• av1an crashing when using vmaf on Windows 10
  2 projects | /r/AV1 | 9 Jun 2022

  It's working. I found this [model](https://github.com/slhck/ffmpeg-quality-metrics/blob/master/ffmpeg_quality_metrics/vmaf_models/vmaf_v0.6.1neg.json) with the help of u/Felixkruemel and I specified the vmaf path in av1an using `--vmaf-path=path to the/vmaf/model.json"`

• How to examine video quality?
  3 projects | /r/PleX | 2 Jun 2022

  Then, after the encode, if you want to compare original vs encoded quality there's ffmpeg-quality-metrics which makes it easy to get VMAF & SSIM scores between the two.

• If FLAC for audio = Remux for video, what's the video equivalent for 320kbps MP3 when it comes to 1080p Movies/TV shows?
  1 project | /r/DataHoarder | 25 May 2022

  ffmpeg-quality-metrics is a good tool to compare before & after encodes. It can easily calculate VMAF & SSIM scores. If I understand it correctly (I might not), then anything in the high 90s for VMAF is considered hard-pressed to be able to tell. Sometimes it hits 100, which makes me fairly confident about those encodes.

• High Bitrate
  1 project | /r/PleX | 6 May 2022

  idk. When I did a re-encode with CRF 23 and preset 'veryslow' it went down to 2,236 kb/s. When I do a VMAF and SSIM test with ffmpeg-quality-metrics I was getting decent scores. It takes the file size down to 2.1GB. So my guess is they either set a significantly lower CRF or set a manual bitrate and aimed for the moon.
