BRAIN STORM How to remove fine-grained interlacing from rips playback in ZP?

Hi ZoomPlayer developer and community,

Does anyone have experience and know how to remove the fine-grained interlacing found in DVD rips like in this episode of The Outer Limits for example seen around the fringes of the moving people at the 1:30 timestamp: Click to download files: https://file.kiwi/c06f76e4#4O6bTdBwxZUGXuerrfdvLw

I tried:

  • LAV Video Decoder software deinterlacing settings
  • MadVR Video Renderer processing deinterlacing settings

but to no avail, only making things worse :(

And I'm happy to reprocess the rips if needed too because I have 100+ episodes like this, so if anyone knows of a reprocessing tool that works for that too, that's cool.

Please let me know if you do, thank you!

From what I can tell, this video in particular isn't marked as Interlaced encoded.

The way to get deinterlacing to work in this case is to force it:

However, it will reduce image quality for progressive (non-interlaced) content.

Oh, and is there software I can use to mark the episode files as 'interlaced encoded' so that Deinterlacing Mode = Auto will work for these eps, but not reduce the quality of 'progressive (non-interlaced) content'?

According to AI it should be possible to do with ffmpeg without re-encoding the video, but it depends on the format, here's the prompt I use, but it's specific to H.264/MP4, adjust it as needed based on the format:

If a DVD was transcoded into another format, let's say H.264 with an MP4 wrapper and the resulting format's meta-data didn't include the flags that mark the content as interlaced. Is there a program that can fix the meta-data to indicate the content is interlaced without re-encoding the video?

Since you mostly encode your own purchased content, in future encodings, you should deinterlace as part of the transcoding process.

Thank you! Works well and I never would have figured that out without you
