How can i install gimp with video support?
Gimp has support for mpeg encode (mpeg 1 e mpeg 2) but it doesn't appear on gentoo ( I don't saw frags for video encode for gimp) |

No gimp guru, but I think that you need GAP, the Gimp Animation Package, that is not in portage. I seems that there is a bug about that in bugzilla, but I have no idea on how updated the attached ebuilds are, since I never used GAP myself.

you should also be aware that it doesn't work with mpeg files directly. It only works on image sequences (it is an image editor after all, not a video editor) The mpeg is just for final output, and there are other programs out there that can take an image sequence and produce a much higher quality mpeg encoding than you will get directly from gimp.

Would cinepaint be one of them? (really curious and not being facetious)

No, cinepaint and the GAP plugins serve a similar type of functionality. And I'm not even sure that cinepaint has any mpeg support at all. (not sure about that though, haven't used it in a long time)
GAP has the advantage of being more advanced. It has some functionality that is very similar to some of the compositing features found in AfterEffects. It's a really great add on.
Cinepaints advantage is that it supports 16 bit and 32 bit float color depths whereas GAP is restricted to GIMP's 8 bit color depth. That's why several professional film houses have used cinepaint for things like wire removal and touchup work. It has the color depth needed in film work. If you are working with video from a video camera though, you can do fine with GAP because digital video actually has less than 8 bit color depth because of the chroma subsampling schemes used. So you don't loose anything.
Either way, if you want to take an image sequence that you've edited with either GAP or Cinepaint, you can encode them into just about anything with tools like transcode or mencoder. They will both take image sequences and encode them to video. They can also do the reverse and decode video into image sequences. There's probabyl others as well. I've used Blender for this type of thing several times, especially when doing compositing at the same time.

Thanks for the complete answer. I installed cinepaint because I wanted to mess around with creating HDR images using my plain old Nikon Coolpix 4300. (It can be done, but it is painful)

Digital cameras don't really offer much in high resolution. The sensors on digital cameras only offer 12 bit resolution, and the color is interpolated. (There are a couple cameras that offer special chips that are layered to produce full color resolution for each channel, but there are only a couple of those)
The best you can hope to do with a digital camera is take raw photos and process them with ufraw. You won't really loose much if you save from ufraw into a standard 8bit/channel image because you can do all the color correction in 16bit mode within ufraw. (color correction is usually where you loose the most information within an 8bit/channel image)
If you really want to get into HDR images and have money to burn, get a medium format film camera (the manual one's are cheap and really fun to use) and a professional film scanner that can handle medium format film (not cheap at all).
