Remove aliasing and moire on 1:1 H.264?
« on: September 18, 2020, 06:48:53 PM »
I wanna try improving some existing 1080p H.264 footage.

I'm considering:
1. Scale back to native 1736x976 using an AviSynth script
2. Perform some type of processing to reduce aliasing and and moire.
3. Perform a higher quality upscaling to 1080p.

It seems MLV doesnt support importing H.264, even though I would like to try out the details panel for the second step.

What would be some other options?

Just record RAW and all will be easier. H.264 won't become much better than it is.

Yes, but he wrote about existing footage, so probably not redoable at this point.
I had good results by scaling H264 footage in GigapixelAI,  it is by far the best software I could find to salvage photos or videos.
