Destructive Editing

Yes there are gradients, but they aren't anything drastic. I filmed with cinestyle technicolor and after applying lut ( look up table ) problem was fixed to some degree. I am using Premiere Pro CS5.

Not sure, but it may be that your subject matter was just less prone to gradient problems. I film a lot of stuff with sky, and sun, and there are very bad gradients. I don't think it is filming method because it does the same thing with files from different cameras and even time lapse from stills.

I have tried every tutorial on the web, add noise, blur more bits... anything. All I get is blurry, noisy color banding. motion jpeg is much much better, and avi, is flawless, with no tweaking needed. Motion Jpeg is not natively playable on Win. Movie Player, which is what a lot of people use. It is easily usable on editors though so I think that is the important thing for most users.

I wish we could convince the industry standard to be avi. For re-editing, I have never found a better file. It can be edited, saved and re-edited with very little loss.

Hi Physics,

I avoid banding by taking my footage through Cineform's NeoScene or Neo HD and upconvert it to 4:2:2. Afterwards I color correct it in After Effects (16 Bit Project) and export it to PhotoJPEG and everything's fine.
The Cineform Software is worth every penny. I did some side by side tests by color correcting directly the footage and it felt apart. What I've also noticed is that objects with red color in it looks much more sharp and less artifacted in the upconverted footage.

I do use cineform, and for a lot of stuff I have to admit it helps. Can't use it for the dslr time lapses. Does not fix some stuff unfortunately, but in general it is great software. I would pay a kidney to make it the industry standard, it is a far superior file.

jets, on that note I was wondering, when upconverting to the avi. with neoscene, and then creating a photojpeg in ae, does the .mov remain 4:2:2?

Honestly I never thought of it because my results were always fine.
But I've found some details about the PhotoJPEG codec on the net and it says:

At 100% it's RGB 4:4:4
At 75% it's Y'CbCr 4:2:2

Great info, I always render at about %91 so should be good. Didn't want to advertise as such unless I knew for sure.

Ya don't go over 95% the 4:4:4 data info really isn't there and you will have a bigger file for no reason. I try to stick with 90-93% and accept the file size that it gives.

Same thing I figured out. I appreciate all the feedback, great to have a circle of experience.

I use a lot of very strong filters, shooting towards the sun at low depth of field. The filters cause an even grading in the video and photos. pjpeg just isn't good at this. I guess I should just use mjpeg, just wish mac users could use avi, then the world peace would surely follow.

Why would someone abuse their pees in this way? Hard to watch...
