Glitches of color in rendered video? (VEGAS PRO 14)

Hello everyone

I've been working on a short film on VEGAS PRO 14 for about a year now and it has been very hard work indeed. Now, it's nearly done and I've finally rendered a rough cut to view on my pc and other devices. However, there has been a problem. I'm seeing glitches of color - purple, green, blue at the bottom of my rendered rough cut. The film was shot in 1080p 24fps and I rendered it with the output format of SONY AVC/MVC 1920X1080 - 30p (*) which I also put into 24fps. Here are some examples of what I'm seeing: https://imgur.com/a/kv8HdkY (purple and green at bottom), https://imgur.com/a/QrdNVVH (purple at bottom). Would any of you kind people happen to know a solution to this problem?

Cheers

Nothing obvious from the details you provided, but check out the FAQ regarding info needed for troubleshooting.

In the meanwhile, what fx did you use; particularly for color grading?

Damn. I'll have to try rendering with different settings then.

Nothing really. I try to keep it natural and control the light in-camera. For a few shots, I mess with the contrast on Vegas but I don't use any fx programs or whatnot. Does it look decent? Might need to do it for certain stuff though, do you recommend any?

Nikon D3300. Not a great camera, but it does the job.

Try MainConcept AVC instead of Sony AVC and see if that makes a difference, or get adventurous and render it externally. Details in this post: https://www.vegascreativesoftware.info/us/forum/faq-how-can-i-improve-the-quality-of-my-avc-h-264-renders--104642/

Alternatively try turning off GPU acceleration of video processing in your Video Preferences, if it is on.

Also, give this a read so you know that the levels you are seeing in Vegas are approximately what (most) viewers will see when they watch your film: https://www.vegascreativesoftware.info/us/forum/faq-why-does-my-video-have-more-contrast-than-the-vegas-preview--104567/
