questions on video compression
on Nov 7, 2011 at 12:40:28 am

Hello all,

Can someone help clarify the difference between a couple of compression settings in FCP's "Quick Time conversion.” What are the differences between "None" and "Uncompressed 10bit?" Other than the size what else?

What happens when I use the "Self-contained" setting? Does this basically use the compressor setting on the timeline? So if I am editing footage from a Sony EX1 camera which is XDcam EX compression, the self-contained setting if left alone will be this?

Thanks for the info

Jess

[Jesse Austin] "What are the differences between "None" and "Uncompressed 10bit?" Other than the size what else?"

None is a dead codec that no one uses anymore, because it is (was) the most inefficient codec ever. Uncompressed 10-bit is essentially the highest quality uncompressed codec on your system, but not used my most, because it to is not terribly efficient, creating big files that need fast RAIDs for playback with dropped frames.

[Jesse Austin] "What happens when I use the "Self-contained" setting?"

You essentially got it right... A self contained QT at current settings without checking the recompress all frames checkbox, makes an identical copy of your timeline, without even losing a generation. Use it to create master QT files for the best archiving and use it as to create web video and DVDS through Compressor.

Thanks David for getting back to me. So using the NONE and 10bit settings are not used that much anymore, I did not know that. I have always had good results from both, but they do as you said create big files.

Thanks again,

Jess

This is exactly why ProRes was developed.

Just to add to the (wise) advices of Mr Weiss, NONE is RAW 8bRGB.
If you ever would need an 8b/RGB codec Animation is much better option.: Also 8bRGB Looseless but makes the files 6 folds smaller than NONE.
