Interlaced video nightmare [Moving to here from digital deliver]

[Roland R. kahlenberg]

Perhaps it’s your Output Settings that are incorrectly set. You should be rendering WITHOUT fields. If things are unclear, then take a snapshot of your Output Module dialog. Also ensure that your comp is set to 25fps and not 50fps.

These are the settings I just rendered with that outputted the same interlaced motion as the original. I double checked that the composition frame rate is set to 25fps. Same result when the footage interpretation is set to lower OR higher field separation.

Any ideas?

Thanks

This is strange – I can only attribute it to (a) a CODEC that is defaulting to rendering an interlaced output or (b) your footage interpretation is incorrectly set (c) scaling and/or positional moves in the layer is causing the interlacing/combing artefact.

[Kyle Bales] “Here is what I’m up against. You can see the motion distortion at the very end. Also it got re-encoded to a different size when I uploaded it so hopefully that won’t derail your analysis :/”

So the interlacing I see in that footage is a common problem, but I’m not sure if it’s due to the resizing that occurred when you uploaded it or if it’s in the source footage. If you turn Separate Fields Off and zoom into your footage do you see single lines of interlacing in that fast motion portion? Or do they look more like big fat lines as seen in the top two images on this site: https://www.100fps.com/

If the latter then your footage was at some point (probably long before you got it) resized without first being de-interlaced. There is no good way to fix this. The best option is to ask for better source footage.

I’m beginning to think it is the latter….

Here is a screenshot of my footage during motion with separate fields set to off. This would be the fat lines you were referring to right?

I’m beginning to believe that the interlacing artefact is inherent in the source video – the VOB files. I know of no way to remove these without introducing other issues. Stay away from such shots when you’re selecting your footage.
