Do you use Cinelerra ? Can you confirm it with screenshots?

<p>There are sentences:
For analog video or MPEG (including DVD) output, the maximum range for R,G,B is [16, 235] (8-bit).
For YUV, the maximum range for intensity (Y) is [16, 235] (8-bit).</p>

<p>Is this saying correct ? I'm thinking that the <strong><em>first</em></strong> sentence contains an error. MPEG has YCbCr encoding ..
What do you think about it ?</p>

MPEG - the maximum range for R,G,B?

Yes, MPEG-2 video is stored as YCbCr, but video editing programs (like [Cinelerra](http://cinelerra.org/docs/split_manual_en/cinelerra_cv_manual_en_14.html#SEC218)) convert the samples to RGB for processing during editing. That range is 16-235.

To get a YUV output in the 16-235 range, the input RGB is also limited.
