Cineform export
 

Hi there!Iwas wondering about premiere timeline export.If I have native hdv clips in timeline,done all editing and want to export my work as m2t or mpg,same resolution as my source,then only choice is media encoder and mainconcept.As i understand it recompress all material to new file?So there must be some quality loss comparabel to original clips?But if i have cineform intermediate already in my timeline and want to export cineform avi is it stays the same as my intermediate clips on timeline?As source format and destination format a the same?

Question is not clear to me.

You can export to any format Premiere supports.

trying to clarify this thing.If i render from native hdv clips new mpg or m2t file,then adobe recompress new file.(because of gop structure)So my output file isn't identical to the source clips.But if i use cineform codec,cineform avi's already in timeline,and my output too cineform avi - a they identical - source and destination file?i mean there is no recompression of the frames?

I will let David answer the question officially, but I think you are asking if the Cineform AVI acts like the DV AVI, that is, what you have on the timeline doesn't get recompressed when exported? Cineform AVI exports to Cineform AVI as is without changes?

You are correct that mpeg files have to have the GOPs reordered, and Cineform does not.

That just that what i mean Steven.

Effective they are the same, but we don't to a digital copy, although we do in Vegas. However, the CineForm codec is designed for multigeneration, you can do 20+ generation of CineForm and still have less loss than a single generation of rendering MPEG back to MPEG.

That's what I figured but wasn't 100% positive.

I can tell you that I experimented with DV when I first started to prove to myself that I could do it lossless. I did the same thing with Cineform when I moved to HDV, and after about 10 or so exports of the same material, importing and exporting and importing and exporting..... I gave up because I could not see the difference.
