I noticed a strange issue when exporting my videos with subtitles recently, and I can't seem to find anyone else with this issue. I hope it is an easy fix.
I add translated subtitles to my videos for YouTube, and they are burned into the video. When I export the video, there is a slight saturation change to the colors when the subtitles appear on the screen. It then goes back when the subtitles are gone. With a video full of subtitles, what you see is a sort of "flickering," that is so subtle, I just noticed it now after uploading a few videos to YouTube.

The actual rendered file is the same. I tried to change my NVIDIA GPU color settings, but the same issue occurs when I rendered the video again.
Anyone have an idea what might cause this? Cheers!

if you are exporting to H.264, try switching the Encoding Settings - Performance
in Export Settings - Video
or try exporting to something other than H.264 like QuickTime GoPro Cineform YUV 10 bits,
then create an H.264 out of that export.
Looks like a Graphics Driver update issue related only to H.264 encoders
Wow! I will try it now. Let's see what happens. Thanks.
Switching to "software encoding" worked like a charm. Howevever, I got a nice GPU to render fast. Any chance that a driver update will fix this issue? I just noticed an NVIDIA driver update is availible now.
Anyway, I will toy around with it. However, you helped me find exactly what was wrong very quickly. Thank you so much for sharing your expertise. Cheers!
Try your GPU rendering again, only this time make sure that Sequence>Sequence Settings> Composite in linear color is unchecked.
Alright. I will try that next. Thank you!
I tried exporting to Cineform and that issue does not happen. It only occurs with H.264 on hardware encoding
