Question / Help Distorted frames in video

[Odjur]

Hey all, I typically record with the following settings:

• MOV container
• H.264 NVENC video encoder (lossless via qp=0 encoder setting)
• ALAC audio encoder
• 48 kHz stereo audio
• 1920x1080 resolution
• 60 FPS

I am using game capture to record video of Mirror's Edge gameplay. I was originally recording without Vsync but started using NVIDIA's Fast sync to make sure that tearing wasn't causing the issue. I have included a normal frame of gameplay followed by the frame in which the video is distorted. Any help in identifying what causes this would be fantastic. Please let me know if there is any more information you need me to provide, and thank you in advance.

Sorry, I just realized that the gameplay images were too large to attach so I uploaded to imgur instead:

Have you tried with x264 or non-lossless NVENC settings to rule out an encoder issue?

I haven't, but this issue also doesn't pop up all the time. There might be ~1 frame per minute, just as an example, of this distortion. I'm afraid of getting a false negative if I switch to other settings; I was hoping that this might be a known issue or something.

Anyways, I will try both of what you suggested later as well and get back.

So I tried removing qp=0 and instead just used a high bitrate, and this did not fix the issue. I did not try using x264 as I am pretty much stuck using my GPU due to its much better performance (GTX 1070 vs. i5-4670k).

I will probably try some x265 NVENC in the future, but I just wanted to get back to this post.

I have tried x264 but didn't get any result.
