I found this video with some guy comparing cineform to native .mp4 footage and the cineform clip has a white line artifact around the mountains but the native clip doesn't. I've never seen this with cineform when I've used it. What could be going on that creates it? Just curious so that in the event this happens to me I know what's going on.

I would take that video with a grain of salt.

I have no idea what the presenter is doing, he seems to compare some, what he calls, raw form with cineform with two totally different gammas.
Also a codec does not add halos, sharpness settings do.

thanks for that. Also what quality setting should I use for cineform? my native footage is avchd. I know I could edit native but I've tried and I don't like how avchd has the clips in a folder structure and I'd like to transcode and rename the files. Also learned the hard way if you rename the avchd .mts clips it messes up the media.

I've heard 3 setting in cineform is high quality and it is supposedly required for DVD but I tried 2 setting for medium and it looked almost identical. Can I use medium quality setting to DVD as well?

EDIT: Heck, even the low quality looks good too.

Cineform works great as an intermediate file, I would say under most circumstances Medium and even Low will be sufficient but if you have the available disk space I would always use the best quality.

Of course DVD requires mpeg-2 (or mpeg-1) so you would have to render the final edit to a DVD format.

So what does cineform.com mean when it says filmscan 2 quality is for rigorous post? How do you define what that is? If I'm cropping scaling, color grading, using green screen chorma key etc is that rigorous post? Should I just use the highest quality since I have the storage space and not worry if I'm doing what's classfied as rigorous post?

Still there?
 
I think the answer depends on the destination.

If you have to provide a master to a distributor then assuming they would accept Cineform (I don't believe it is a common format) you should use the highest quality.
But if your aim is to use the intermediate for a personal DVD or Blu-ray version or a YouTube upload then medium or even low seems quite sufficient to me.

so what about the instance of major scaling, green screen work or clips that need to exported multiple times like say you have a clip that's been keyed from a green screen and you have scaled down that key to match a shot. Should that originally be at filmscan 2 just to preserve that amount of scaling etc or not?

Is there any issue with just using filmscan 2 for everything regardless if I don't know what my destination will be?

There is never an issue in using the lowest compression as long as you have enough disk space and the disks are fast enough to handle the bitrate.
