Bug Report Small bug with "Encode in Full Range"

[DiabloRX2000]

Not a major bug, but while making a test capture with OBS 0.64b, I noticed that the option "Encode in Full Range" under Advanced tab has its effect inverted. When the check box is marked, OBS is actually using TV color range instead, and when the check box is unmarked, then the program is using PC color range.

Check the picture below which contains a test pattern from an article about Nvidia cards.

Looks like your renderer doesn't support it. Why are you using full range?

As you can see in the second image, OBS did the capture in full range, but when the box was unmarked. That's the point of this bug report.

Have you tried this with x264? same results? also with out your custom options? just want to find out if this is just a quicksync thing or everything. it sounds like its a quicksync thing since most of us run without the full range option to stream to twitch, which cant use full range currently.

I think you're confused about what full range is. It's not the same as dynamic range.

Normally, luma is expressed digitally in the range 16-235, where 16 means black and 235 means white. Values outside of that range are clamped. With full range, luma has the range 0-255, where 0 is black and 255 is white, and a flag is set in the bitstream to indicate this.

Most players ignore that flag, resulting in crushed blacks and whites. Which is fine, because no one uses full range. Limited range is enough for most content.

Yes, I have tried this with x264 and the results are the same.
