I just hate it how the same video file looks so different on TV and on a computer screen. After lots of trial and error, I was able to get with Vegas a picture that looks good on my TV (playing h.264 via the Sony PS3), even if it looks weird on the PC screen. Vegas already has a “Computer RGB to Studio RGB” template under its “Color Corrector” plugin, but this was not enough to make my footage look good on our Sharp rear projection CRT TV.
So, you bring up the “Color Corrector” plugin, and you change the following:
Saturation: 1200 to 1250 depending on the scene.
Basically, you just need to f*ck up the RGB histogram by narrowing it down, and making it look completely unnatural and warm on the PC screen in order to look normal on (my) TV. Your mileage may vary, so you will have to do your own tests.
