Interlaced or de-interlaced footage for compositing in AE?

[Mark]

I would say that if you interpret the footage correctly in After Effects it doesn’t really matter.

But if you rotoscope interlaced footage, you need to separate fields (file>interpret>main) then drag the clip into a comp whose frame rate is twice that of the footage. This way you’ll be rotoing on every field.

In the case of 29.97 fps video, the comp should be 59.94. Then you render at 29.97.

for the best results without having to rotoscope each field individually, it is much better to use progressive footage.

Hi Uwe,

when working with interlaced footage in a roto situation try this:
1]import & interpret footage
2]place footage in Comp
3]go to the compostion settings and change frame rate and duration (I work In Pal so from: 25 Fps to: 50 fps in effect your doubling frame rate)

what you are doing is looking at every instance of movement(every field) the benefit of this is so you can see and make adjustments on the fly which sometimes can be hidden on a progessive scan monitor this will give you more temporal resolution when Rotoing.

hope that helps,

regards

Josh

Thanks for your answers. On this site it seems, that the author favors the method with de-interlaced footage:

However, the advice of Steve is very helpful

Is there any way that looks good to deinterlace footage straight in AE? Steve what you were saing about interpreting would you need 2 layerse one with even and one with the odd fields?

Thank you Josh. Of course this helps…
