Yep, that's the setting I always have.

I think more information will be needed. What output format? What input footage format? Does it concern a specific clip or all project?

Sorry, I'm not sure what exact info needs to be given, so just ask and I'll tell you.
Both my output format and my input footage are MP4 format. And as far as I can tell it happens for all of the clips. Not a significant change in brightness but noticeable enough.

Befere I ask you about the render settings - please check if your preview screen has this setting off:

Options=>Preferences=>Preview device=>Adjust levels from studio RGB to computer RGB = OFF

Yes, that setting is unchecked.

Did you check the final video on a different computer? The issue may be settings of your graphic card.

The problem is that you cam program your graphic card driver in a different way on a drifferent program. For example it may override your video player settings and change its dynamic range from 16-235 (Studio RGB) to 0-255 (Computer RGB).

That's good to know. I think I'll do more research on that. Also it doesn't seem to make a difference what screen I watch it on...The trouble is I'm just not quite sure how to go about correcting my driver.

Well, the graphic card settings MAY be the issue, but not for sure.
My thesis is that the problem is caused by incorrectly set dynamic range (16-235<=>0-255) in your rendering software or in your video player.

In your rendering software the problem may be caused by:
- Computer RGB <=> Studio RGB settings (already checked),
- codec settings (not checked).

In your video player the problem may be caused by:
- internal video player settings (analyzed now),
- graphic card setting (analyzed now).

So, before we start digging in your graphic card settings, let's eliminate video player issue.
What video player do you use? Did you try to play the video on a different software?

I see. And just so there's no confusion, when I say I've tried Computer RGB to Studio RGB, I'm referring to the preset in Levels. My video player is VLC, and I suspected that might be an issue too so I tried it with the other video players on my computer and they look the same.

OK. So let's check graphic card settings. Unfortunately I will be able to guide you through NVidia's graphic card settings.

For NVidia:

Right click on Desktop=>NVIDIA control Panel=>Video=>Adjust video color settings=>How do you make color adjustments?=> With the video player settings = ON
This setting means that your video player will decide if the player video is displayed in Studio RGB (16-235) or Computer RGB (0-255).

You may also try selecting "With the NVIDIA setting" => Advanced => Dynamic range = Limited (16-235).
This setting will force all your video players to use Studio RGB (16-235) color range, which result in displaying more contrasty video.
If it won't help, return to previous settings.

Hmm, well actually I don't have NVidia...when I right-click on the desktop I get this option: AMD Vision Engine Control Center
And when I click it I don't see anything similar to what you describe.

Unfortunately I don't know AMD Radeon drivers.
However I've found a thread concerning dynamic range adjusting:
http://forums.amd.com/game/messageview.cfm?catid=449&threadid=163260

Or maybe our forum colleagues who own radeon cards will help you in adjusting.

Before applying any changes, it would be good to note down the initial values to avoid messing up your graphic card settings.

Hello!

I know this is years ago but I’m actually having this problem now. I tried applying the fx “Computer RGB to Studio RGB” but when I render it, it freezes at a certain percent, and the estimated time remaining ends whilst the percentage stays at 6%, so it doesn’t end. I tried everything, re-installed again and again, and still the same.

So basically, I have two problems:
(1) The brightness/contrast increases after rendering.
(2) When I use fx (even transitions), it freezes whilst rendering.

I hope you guys can help me. 🙏🏼 Thanks!

Vegas Pro does not encrease the brightness or contrast after rendering. Your player does this.

Hello,

Thanks for the response. However, I’m sure it is Vegas that changed it. I also tried to view it on my phone, and we post it on the social media account, and the brightness really increased.

We have a specific colour palette we use, and whenever I render it, it becomes brighter than the colour we use.
 

I really hope there’s a fix for this because my job really depends on this. Thank you!

We had this topic dozens of times since 20 years and the last one is from about two weeks ago. Except of WMV and XAVC-Long QHD output (which seems to be a bug) Vegas Pro definitely does not affect the video levels if no FX where used. But many or most players expand video levels either generally or due to some meta data. Also the computer's graphic device may be set to expand video levels. Vegas Pro doesn't.

Re-import your rendered video into Vegas Pro again and check via it's internal preview and via the waveform monitor and you will see.

Marco is 100% right about Vegas and levels.

Do try to get the Computer to Studio levels preset to work to give the players video range footage. If it's not rendering with that output Fx in place, disable the GPU preview when you go to render and then enable it again when you want to render. If that doesn't work, also change dynamic ram preview to 0MB from 200.

One important determinant of continued employment is you ability to understand the way your tools actually work and your willingness adapt. Use the tools in this link to prove that Marco is correct and go be a top performer.

Vegas Pro Levels, Last and Final # 1

PS

Don't expect a raise any time soon, though.

So I tried other video editing software and same thing happened, so I think it really is because of the graphic device as Mr. Marco said.

As for my employment, my boss is not actually strict but I really want to give my best when working. So thank you very much for all the replies and new information! I guess I need to upgrade anytime soon haha.

Stay safe everyone!

 

@Marco. @john_dennis
No one has yet grasped this as quickly as aceyabey.
When I think of the discussions a few weeks ago .......;-)))))))

Here is a traing project for you. It opens in Vegas Pro.
