DVCPRO HD deartifacting?
Hello everyone,
is there any way to de-artifact DVCPRO HD material (8bit 4:2:2) inside of Final Cut Pro 5 to 4:4:4 with a plug-in or something like the Magic Bullet Deartifacter? The problem is, Final Cut Pro software-only does not support a truly uncompressed 4:4:4 timeline, so I cant’ really use a chroma deartifacter plugin…or can I?
Any insights very much appreciated!
Thanks in advance,
Lasse -

DVCPRO HD is compressed on tape, or as a file if you used the HVX-200. Nothing will get rid of the compression artifacts. The best you can do it go into an uncompressed setting when you color correct so that you can avoid compressing it any further.

Hey Shane,
thanks for your fast reply. Currently, there are some deartifacter plugins like the Magic Bullet Deartifacter (part of Magic Bullet for Editors) or the G Nicer from Graeme Nattress (part of his Film Effects plugin set) or the Remove DV artifacts AE plugin by Stu Maschwitz. The way I understood it, those plugins do deartifacting by rebuilding the missing chroma information from the other channels of the picture.
So yes, the compression is right here in my files, but I hoped there was a way to reconstruct it. I just wanted to do it before color correction and effects work. Problem is, software-only FCP can only use a 4:2:2 timeline, so no matter what plugin I use, the signal will still be a 4:2:2, limited by FCP’s sequence preset. Not?
BTW, I love you little frog blog!
All the best,

Well, the DVCPRO HD codec is 4:2:2 only, so aren’t you limited by that? Dropping it into a 4:4:4 timeline won’t suddenly make it 4:4:4….if FCP had a 4:4:4 setting.

G Chroma Sharpen in Film Effects will help fix up the chroma for you. You can render 4:4:4 in FCP by using a RGB codec, like PhotoJPEG100% or Animation 100%. All effects in FCP are done in 4:4:4, but if the timeline is 4:2:2 they get converted back.
DVCProHD is only 4:2:2 at it’s 960×720 size, so it’s actually worse than 4:2:2 when you expand it back up to the full 1280×720 size, for example, so if your timeline is 1280×720 uncompressed for instance, you could see some benefit from chroma upsampling (depending on footage) even though both are 4:2:2.
Best thing to do is try and see on your footage.

I’ll do just that. Thanks to both of you for the tips.
