Deinterlacing = Quality loss?
on Mar 29, 2013 at 8:34:17 pm

I have a general question:
Does deinterlacing video material automatically mean quality loss?
I have read that during the deinterlacing process it throws away half of the image information so that would be no question that the deinterlaced footage has less quality.
I am deinterlacing 50i footage to 25p using Compressor.

If you use Compressor, it will be a LOT better than using FCP's Deinterlace effect.

Tell you what: find a 10-second section of the timeline with a lot of motion in it. Export that section as a self-contained QT. Deinterlace using Compressor. See what you think.

i haven't used compressor to de-interlace,
the main problem is that you cant see your results on an external monitor

in the past i have used the NATTRESS smart de-interlce plug in .
it is very god, best there is for use within FCP in my opinion.

i took the same short clip, and applied 3 different de-interlace plugins i had, and on a blind test Nattress came up best.

Nattress, ReVision FieldsKit are very good.
Jess Deinterlacer (free) is said to be very good too.
The FCs default de-interlacer and QT deinterlacing, are to be avoided.

Oh yes, I tried and found out. So I started using Compressor. But good to hear, I haven't done anything wrong!

Thank you also for all the other suggestions. But yeah, worst thing would be the built in FCP effect or QT.
I will have a look for the other suggestions you mentioned. Thank you so much, to all, so far!
