Get Metrics with different resolution

Open 89z opened this issue 3 years ago • 7 comments

I am trying to use Get Metrics as shown here:

https://reddit.com/r/ffmpeg/comments/qqmk8p/how_to_compare_video_quality/hk20eq5

I have the same video with two different resolution:

Resolution:1280x960 Bandwidth:3122000 Codecs:avc1.640028, mp4a.40.2
Resolution:720x544 Bandwidth:4619000 Codecs:avc1.640028, mp4a.40.2

Is it possible to compare these? I just want to know which one is the better quality.

Yes, the metrics utility should resize them to match

It didn't, it just gave me an error

Well then show me that error

Make sure you enable this

Make sure you enable this

Thats a good idea. I didnt try that. However now that I am trying it, I still get error:

Ready...

Can you send your ffmpeg log?

I don't know how to do that
