Random jagged frames when encoding 1080i footage

Post by kenzarxv »

Description of problem or question:
Random jagged frames when encoding 1080i footage

I have TV shows I recorded and wanted to re-encode them as they're quite large in file size. We're talking about 20gb+ .ts 2-2.5hr shows.
They play very well using either IINA (mac) and MPC-HC (windows) with deinterlace turned on at a smooth 60 fps.
However, when I try to encode them either using H265 or AMD VCE, I get these random jagged frames in the middle of the show. I am playing back the source file and those jagged frames doesn't exist.
Any idea what's causing it and what settings I can tweak? I'm almost tempted to just play it back and record my screen using OBS.

Reference comparison: https://imgur.com/a/UuoOQjb (both are from the same encoded file, just different time stamps)
Settings: MKV, Detelecine, Decomb Bob, H265 10bit or AMD VCE, 60 fps Constant.

Try turning off Comb Detect. That forces the decomb/deinterlace to be applied to ALL frames, not just those that are obvious to the filter.

Made a quick 120 second preview and it works perfectly! Will try to re-encode completely. Thanks for the help!

Unless you're trying to take this into an editor (in which case you're using the wrong settings otherwise), don't force constant framerate, use variable (peak) framerate.

Does it make a big difference with the file size or quality?

Small improvements to filesize and playback smoothness.

Will try to experiment with my next encode. Still trying to find the sweet spot. Thanks!
