Hi
Yet another levels question.
I've got video from the GH5, and have used the built in test chart to get a couple of videos, both 8 bit 4K. One chart at 0-255 range and another at 16-235 range.
I was expecting on the time line that the full range video in the preview would look good level rise, and that the 16-235 video would be washed out a little as the preview/timeline is 0-255.
However what I found is both charts are exactly the same in Vegas, and looking at the scopes they are, with 0 and 255 being the top and tail for both.
When I've checked the MOV files with MediaInfo, the full range sample shows Color range as Full, and the 16-235 level sample as color range limited.
I'm thinking then that Vegas is decoding these files and taking the levels into account, and is applying a studio to computer level conversion on the limited range file, is this correct? This is my first time using MOV files and I didn't think Vegas was this clever.
Regards
Phil
