(help request) Video rendering incorrectly, preview window looks fine

Alexander-Schmidtka wrote on 9/23/2020, 9:19 AM

My preview window looks fine in vegas both during editing and rendering but the final video file has weird artifacts occurring, almost looks like compression. It occurs at about the 0:06-0:08 mark.

I'm using Magix AVC/MP4 on the Internet UHD 2160p 59.94fps (NVIDIA NVENC) template.

Try rendering without using NVENC. Do a CPU only render and see if there is a difference.

@Alexander-Schmidtka

Did you a default render with that template or customized?
If I render 4K to that template on my laptop from signature I get a bigger file with higher bitrate.
Which is your Nvidia GPU and which exact driverversion is installed for that GPU?

Rendering with the same template but without Nvidia NVENC resulted in the issue not occurring, going to try updating drivers on the card and see if it persists (it probably will since im usually on top of those updates)
