” Iknow it doesnt gain any quality, but does it degrade”
Not in a way that you’d notice.
Where does all the extra giga bytes of data hide?
Nowhere, it’s all just ‘padding’ or extra fat.
Do i lose picture quality if i have an uncompressed movie, import it in PP,and export it back as uncompressed?
Maybe, but you’d probably not notice it unless you really knew what to look for.

Have you tried playing it back on your PC using VLC?

re 2k & 4k, right, glad we got that sorted!

Ok, lets try this another way; What frame sizes are you working with from RED?
To export by Reference:
FIle..>Export…>Quicktime Movie. Select ‘Using Sequence settings’ and deselect ‘Make Movie self contained’
If it’s DVD you need to output to them in 99% of cases you can only use MPEG-2, compressor has plenty of presets.
“Since this post, I compressed an h264, an uncompressed 10 but 4:2:2, a redcode, HDV, DVCPRO NTSO 48khz, MPEG 50/mbps encodes, but nothing seems to look like the same as the fcp picture quality.
Like I said, RED is the very high end, HDV, DVCPro, NTSC and MPEG are not. There is no way you can retain the picture quality using those formats, that just the way the cookie crumbles.
However, done correctly H.264 can retain most of the picture quality, but you need to be pretty expert with your tools to achieve this and it would appear to me that you are still struggling with the basics. I don’t mean any disrespect by saying that, you are working with highly complex and complicated applications and tools.

Make sure the PC has Quicktime installed.
If you are working with DV, simply export to the DV codec
If not try exporting to the Quicktime PhotoJPEG codec set to 75% on the quality slider.
If your file sizes are too big – use MacDrive from MediaFour to sort out the drive issues

I’m really confused
2k / 4k when referring to cameras like RED usually relate to frame size NOT bit rate. With video there are obviously no such datarates as 2K or 4K per second (unless you deal with very miniature frames sizes)!?
When you are working with RED you are working at the very high end of video, you really need to know your stuff, you can’t fudge around like this.
I’d be exporting a quicktime reference file to compressor, you want to avoid transcoding to another codec (like Uncompressed) before H.264
You must be using compressor (or similar) to do you encodes but you HAVE to find out how your material will be played back at the film festival. You can’t just turn up with an H.264 file!
Your grain issues have nothing to do with Gamma, the two are totally unrelated. There are Gamma problems with Quicktime H.264 but they don’t manifest themselves as huge increases in grain!

“Yes…all the options are available regardless of the format, the codec etc. I think trueSpace is converting the image somewhere before it get’s compressed.”
So that tells me that Truespace does not honour a codecs PAR, as we all know that DV is non-square.
I don’t find it surprising really, only the better (and very expensive), higher end 3D solutions work well directly exporting to video; 3DS Max, Maya and SoftImage spring to mind.
With the likes of Truespace (and I’m not belittling it whatsoever) you are far better off exporting to an image sequence and working with that externally. Let a video specific application like AfterEffect or you NLE handle PARs, SARs and DARs!p.s. BMP and JPEG are square pixel formats (even though the JFIF standard allows for aspect flags to be written, it’s rarely if ever implemented), so Photoshop is correct..

How about https://www.yousendit.com/
By taking a look at it we should be able to figure this out once and for all!

No worries.
It would be easy to tell you how to compress your video down to a small size but in turn that may introduce a nightmare moving back and forth between FCPs.

This is more of a workflow thing, I’d suggest the guys in the FCP forum would be better qualified to answer.
