Felt sorry for making you busy, but I have something to say about this :D

I have a Canon 5d mkII, it produces h264 .mov files 38mbps, even if it’s a compressed format I see no color banding at all when I shoot gradients like sky or clouds, I’m desperately trying to match the same encoding settings but I’ve had no luck until now.

You are comparing real footage to motion graphics here. Real footage recorded with a cam has no perfect gradient, there is always a bit of noise which makes it easier for h264 to get rid of color banding.

That’s why it is good to apply the noise effect with 2-5 percent over your motion graphics. They look more natural, and then you can get the same banding-free result as your 5d.

Creattive thanks for your reply, I was mixing the two things, that’s why I got a bit confused.

However I guess this is related to bitrate, so my question is: do you know a way to get an higher bitrate clip with QT Pro 7 or another software? Probably it is not possible within a .mov container… I’m sorry but I don’t like adding grain :)

Thanks for your patience :stress:

I’m not using QT Pro, only AE, but adding grain is the only thing that worked for me and I don’t mind it since it makes it more natural.

you can try to add some slight colour variations in it by applying a 4 color gradient over everything and lower its opacity to 1-2 percent. that helps in removing banding, too, since there are more different color informations.

Thanks for the suggestion, I’ll try, after all if I increase the bitrate too much I’ll probably end up with a very large file, so it would be better to use png…

Once the project is complete, I’ll usually transcode the final image sequence into a mildly lossy codec like ProRes HQ. This is neat, storeable and visually lossless. Perfectly good for archive. This is my master file and I will use this to make any heavily compressed versions. I use Compressor from Apple, but Quicktime Pro has a pretty good h.264 exporter (and compressing from ProRes doesn’t give colour management gamma shift problems like Lossless/Animation codec does)

I’ll give this a try as well.Thx for this workflow

The point is: it is possible to make an h264 clip withouth banding, but why we cannot match the same settings of the camera with QT Pro or other software? Do you know any other software? I don’t think so, otherwise you wouldn’t advise to add grain and Noise HLS Auto effect etc. :(

I understand that there are different solutions, depending on the final products specs, but don’t you think it would be worth to have a look at this? It could solve al lot of problems for me and I believe many other users. I’ll keep searching for this.

Thanks again

Stuff you shoot with a digital camera has noise / grain already in the image. Quite apart from which there are very few perfectly smooth gradients in nature.

The reason that I’m advising people to add grain / dirt to their graphics before compressing is to make them more like the stuff that a camera shoots.

It’s not to do with the compressor, old bean…. it’s to do with what you’re compressing.

Thanks very much Felt and Creattive for sharing your knolwedge… I’m giving up, my search for the truth is ending here (probably :))...

Felt sorry, sometimes it’s not that easy to express what I really want to say, I didn’t mean to criticize your valuable experience…

Old bean :silly:

Hi,

Okay,i did a couple of render test.I rendered an image sequence out of Æ. i then used this master render for Compressor to create a h264+Apple ProRes422 file.The quality is fine but the h264 render is slightly darker.Is this normal,felt?
