FFprobe Can Tell You Where a Video Generation Pipeline First Went Wrong
“The video looks pixelated” is a useful report from a viewer, but it is not a diagnosis.
The visible problem may have entered during capture. It may have been introduced by an editor export, a messaging app, a cloud-storage preview, a video platform’s transcode, or the player’s current rendition. Those failures can look similar while requiring completely different remedies.

Upscaling a clean master because a browser temporarily selected a low-resolution stream adds another transformation without fixing the delivery problem. Re-exporting a compressed attachment at 4K creates a larger file, not a recovered original.
This workflow uses FFprobe and FFmpeg to answer a narrower, more defensible question:
Between which two available generations did the measurable and visible quality change first appear?
FFprobe cannot decide whether a video looks good. It can make each file report comparable facts,...
