Are you sure you want to use de-interlacing? You’re effectively throwing away half the resolution and filling in what’s missing with what’s left.
yeah i second this. de-interlacing rarely improves quality. and if we are playing back on TVs, you won’t notice the interlacing if you have proper hardware. I hate interlacing, but once you have it, better to stick with it.
Totally understand if you can’t do your video editing this way though, your call.
