I hope this isn't a re-post, but I've been reading around online lately and keep hearing different things.
I have been using ProRes 422LT with Canon DSLR's.
Does anyone know the difference between 422, 422HQ, 422LT, 4444, and 422 proxy?
I hear some are better for color correcting and stuff, is one of them just the best quality in general?
Whats up??

It is generally agreed that ProRes LT is the only ProRes format worth using for DSLR footage because that is the farthest you can "stretch" DSLR footage. This is because the higher ProRes formats (ProRes, ProRes HQ) work in higher color space than what is possible, and it actually degrades footage.

ProRes Proxy is exactly what it sounds like; all the files you use are proxies. They are designated "placeholders" with in/out points, properties, filters, settings, etc. embedded into them. Once you are done editing, you render the proxies, which implements the actual footage where the proxies were. Proxies are a staple when using large files, but unnecessary for DSLR footage unless your computer is extremely slow.

The numbers refer to the chroma subsampling.

you should read this wiki article which will hep explain some.
http://en.wikipedia.org/wiki/Chroma_subsampling


Most DSLR footage is 4:2:0 which is why 422 HQ and 4444 are really not needed at all. They will also create massive file sizes.

and in proress 4444 the fourth 4 is for alpha.

is there anyway to export a video to from fcp to AppleProRes for the web? like for vimeo, and keep it under 500 mb ?! because i randomly tried exporting a video in it just to see how it looked, and the colors were amazing, but the file was rather large..

ProRes isn't a finalizing codec. That's why h.264 was invented.

So basically I should just stick with 422 LT when dealing with DSLR footage?

Anything more is not only overkill, but will degrade footage. ProRes LT is grood.
