Try rendering to MainConcept AVC using the Internet HD 1080p template. Then view the output using the VLC media player. I’m getting the exact same colors as your example with this combination. If, however, I use the Windows Media Player with the exact same file, I get different colors. So the media play is most likely your problem.

Since Vegas Pro converted from DirectX to OFX plug-ins it changed the way you must enter colors. Colors are now specified as values between 0.0 and 1.0. Think of it as a percentage of 100%. To convert RGB colors simply make them a percentage by dividing by 256. So 198 / 256 = 0.77, and 44 / 256 = 0.17, and 22 / 256 = 0.09 so 192,44,22 becomes 0.77,0.17,0.09,1.0. The final 1.0 is the alpha channel.

July 14, 2013 at 10:05 pmHi John,
Thank you so much for checking this out and also the explanation of the percentage colors. Armed with that knowledge, I feel I am back in control! Yes, you confirm my gut feeling that the media player is to blame here. It’s a pity because it is likely to be the clients player too as VLC is a bit obscure for clients.
Will try your template suggestion. Thanks again
Best
Paul

March 11, 2015 at 4:57 amHey Laird, Thanks to your post i believe i have found the issues of getting footage too dark, saturated, contrasted after rendering mp4.
Im not sure if someone figured this out on here but After reading that you actually previewed your footage in the “Video preview on external monitor” by clicking the little blue monitor icon. But when i did that i found that i was still looking at the same exact preview as before (brighter). So i decided to look for some kind of preference and voila There it was.
by the way, It would be best if you had two monitors but works fine with just one screen.To avoid rendering and then later find out that the video rendered is actually darker then original edited you must right click the little blue monitor icon in the preview video tab and click on “Preview device preference” or just go to menu bar > Options > then Preference > then “Preview device tab”. There you will find under “display adapter” > “Adjust levels from studio to computer RGB”. That needs to be “CHECKED”. Once that is done, you can now see exactly what you are color correcting in preview but only in the extended monitor view.

June 8, 2015 at 8:30 amThank you for spelling it out in plain English…. I just figured it all out right before getting to your post at the bottom of the page. Same problem as the others… never knew I had to have external 2nd monitor and that it had to be in “full screen” mode in order to show the difference! UGH finally. Thanks cows!

Thanks so much for this! I never had a problem with HDV but after buying a new camera I could not render without the contrast increasing and the blacks becoming unnatural and loosing detail. Now it stays the same 🙂

November 28, 2018 at 7:18 pm[John Rofrano] “Our Samsung HDTV looks NOTHING like our Sony HDTV (not even close!). That’s the “state of the art” when it comes to TV. You’re not going to be able to fix that.
What you should do is buy a hardware calibrator like a Spyder4Elite and calibrate your monitors and show your client that it looks correct on your monitor. “
Ah ha! My original problem was that when I rendered a file it would increase the contrast and I would loose detail in the dark areas OR SO I THOUGHT. In Vegas 13 all would look fine in the preview window and the second preview monitor (both Dell U2414H) but once rendered and played in Windows 10 “Films & TV” or Quick Time Player, it would appear darker. I then applied the suggestion [Thomas Felton] “The best thing is to apply the Levels filter and select computer rgb to studio rgb” and I thought I had cracked it but then quickly realised I hadn’t.
When I took an original untouched file dragged out of the camera and the same file clean rendered in Vegas and played it on our calibrated 4K Samsung TV they looked just the same. The file rendered with the Levels filter now looked too bright.So the Red Herring for me was that when I played an untouched file (dragged and dropped straight out of the camera) in Windows 10 “Films & TV” or Quick Time Player, it would play PERFECT, exactly the same as it would in Vegas BUT, once I had rendered the file it would then look darker in those same players, leading me to think the problem was in the render.
I confirmed this wasn’t the case by bringing the rendered file onto the time line in Vegas next to the original and they played exactly the same in the preview monitor.
I now realise that if I want to check the final render I have to do it within Vegas (or on my calibrated TV) but not on the Windows players I have.
I can sleep now but I am left scratching my head as to why those players play the original file perfect????Vince

November 28, 2018 at 11:18 pmVince, the problem is your players and TVs are probably showing different levels. So you are not comparing Apples with Apples. In my experience most TVs show the limited or Studio RGB range but of course if you play around with Brightness, Contrast, Backlight etc the results will be different.
With your pc check your graphic properties. Is it set to show videos with Full or Limited (Studio) RGB range. Is it set to allow players to use their own settings or not (although I’ve found players can sometimes override this). Check whether your players give an option to set the full 0-255 or limited 16-235 range. Only when you have all your equipment showing the same range can you do a comparison.
