Question / Help Occasional keyframe/compression artifacts while streaming

[dadangg]

Occasionally while streaming to Twitch through Restream.io, the video would have "light shows" which I'm assuming are the keyframes getting dropped. What settings can I change to fix this?

Example:
https://clips.twitch.tv/ViscousSuperMarjoramDatSheffy (has light shows)
https://clips.twitch.tv/ConsiderateSpicyWombatAMPEnergy (every other time it's clean like so)

I have the following output and video settings:
Encoder: NVENC (new)
Rate Control: CBR
Bitrate: 6000 Kbps
Keyframe Interval: 0 (same thing happens with 2)
Preset: Quality
Profile: High
Look-ahead: unchecked
Psycho Visual Tuning: checked
Max B-frames: 2
Base Res: 1920x1080
Output Res: 1920x1080
Downscale Filter: Lanczos 36 samples
FPS: 60

My pc specs:
Ryzen 5 1600
GTX 1070
16GB 3200MHz

Your log is unreadable due to whatever broken page you have in your browser source spamming websocket connections.

I cut out the bits I believe are irrelevant since it was approaching 24 hours of streaming. The websocket connections are from race overlays.
Here's the cut down log: https://pastebin.com/5iLWSXqM

Try streaming with RTMP instead of FTL, I believe that's causing the issue.

Thank you, I'll try that out when I get the chance and report back.
