Fixing jagged edge with red background.
Hello all.
I have a question. I am making a fairly large DVD. The majority of this DVD is of a sitting man, giving a tutorial, with a red background. A spot light is lighting the space over his left shoulder on the backdrop. as with most things that are red there was some pixilation and jagged edges with on his shoulder. I cleaned these up using the Color Smoothing_4:1:1 filter under the key tab. This took care of most of my problem, but my client is saying that they still see some strange pixilation that would be “very obvious”. Upon further review of my DVD I noticed a extremely minor jagged edge on shoulder of my videos protagonist. What can I do to further solve my jaggedness and pixilation issues?
Thank you for the support
Thomas.Cheers.

Is the original material DV?

Natress Filters has better than stock filters available (for sale). DV and DVD do not like reds, this setup should be avoided if you do this type of project again.
Couple of things that might try, Look at Natress’s filters for upsampling to 4:2:2 and then do some color corrections, make sure the chroma levels are within broadcast safe and you may want to reduce the saturation even further.
I better encoder maybe needed also. Compressor does a good job on most things but it seems to have more trouble with reds then Bitvice or others.

What was the material shot on? How was the material digitized? If it wasn’t shot DV, maybe working in a 4:2:2 10-bit codec to start would be useful. It is good to look at the tape and see what you actually have. Are you using broadcast safe or color correction filters? Sometimes, that exacerbates the problem too, especially in a compressed format. Possibly, you could try to desaturate the red a little using a CC 3-way limit effect. But if this was shot DV, that compression could be on the source recording and then you would be limited in possible solutions.

to respond to everyones questions, this was shot on Mini DV, but we used a 16:9 aspect ratio , and we used a deck to digitize it. Also, we do have Natress a wide verity of Natress filters, can anyone recommend a good one to up sample to 4:2:2?
Thanks.
Thomas.Cheers.

I was just looking at the borisfx website, and I see they have an After Effects filter called DV fixer…
Maybe that is worth a try in conjunction with other options too…
Good luck.
