Did you also watch in on a computer monitor?

It's a bit subtle but If you watch closely, the blue color pixels are flickering/wavering up and down fast in the whole flicker.mp4 clip and in...

Panasonic DMR-E50 TBC image flickers?

I have a Panasonic DMR-E50 DVD recorder, which appears to have a line-TBC which stabilizes the video somewhat, and can be used as pass-through while capturing VHS, but it has a big caveat, in bright...

Looks better indeed, for this clip at least. I see you also did a lower gamma. What syntax did you use for these?

Thanks for the input. I'll do it with the xaa antialiasing in vapoursynth.
Rests the question, is it best before or after deinterlacing?

OK here it is attached: 18516

I was briefly thinking it could be something to do with the camera'a digital zoom, but it's also visible in wide/zoomed out shots.

That doesn't seem right, or I'm doing it wrong :screwy:
It resizes to 2150x1080 instead of something like 1350x1080
This is what I've used:


cropleft=14
cropright=12
croptop=0
cropbottom=8
