Pixelated Reds
Hi,
I’m editing video which I’ve taken from a DVD .vob file and have converted into a DV .mov file. The picture quality is excellent except for instances where there are reds, in which case the red parts are extremely pixelated. Unfortunately the original .vob/mpeg2 files also have the same issue when I view them.
Is there a specific reason to why it’s doing this? And is there any sort of solution? The final product will be shown on a projector.
Any info or help would be appreciated! Thanks!

since you got this off of a dvd, I assume that we are talking standard definition (mpg2?).
Red is a very bad color for standard definition, which (in your case) you compressed further to go to dv.
You are experiencing something we all have….your problem is quite simply that the files are compressed, and red is the most unforgiving color. It was probably introduced when you went to dv.Not a lot you can do, as it is what it is!
However, try editing in a higher quality codec, like 8bit uncompressed.
That may help a bit, if not solve your issue.If that doesn’t work, try to re-export from your dvd (vob) in uncompressed or ProRes or something higher quality than dv.
hope that helps.
When I ran into this problem, I didn’t know about the cow (may not have even been around WAY back then), I had to troubleshoot my system for several days, talked with at least 4 engineers, and really was never satisfied with the answer. Its really quite simple.

I had a similar issue working from DV tape, which I solved by applying the chroma smoothing 4:1:1 filter.
Not sure if this would work on your dvd source – the pixelation may be ‘baked in’.
How did you transcode? Mpeg streamclip? Perhaps you could go to prores instead of dv…
