Here are my current OBS settings. I have a 5090.

Recording Format: .mkv

Video Encoder: NVIDA NVENC AV1 {AV1 is new but way better than H.264)

Audio Encoder: FFmpeg AAC

Rate Control: CQP

Constant QP: 14 (14 = reference/archival quality, 15 = visually lossless for 99.9% of people)

Keyframe: 0

Preset: P7 Slowest (Best Quality)

Tuning: High Quality

Multipass Mode: Two Passes (Quarter Resolution)

Profile: Main (High: lags footage badly but the quality is outstanding)

Look-ahead: checked

Adaptive Quantization: checked

B-Frames: 2

B-Frame as reference: Disabled (Testing: Middle b-frame only)

Split Encode: Auto (Testing: Two-way split)

Advanced Setting:

P010 (10-bit, 4:2:0) - Enables 10-bit HDR pipeline.

Color Space: Rec. 2100 (PQ) - PQ transfer curve for YouTube HDR (preferred over HLG).

Color Range: Full (Matches HDR full dynamic range (common for recording)

SDR Peak Nits: 300 fine, Grok suggests 203 - Tonemaps for SDR viewers.

HDR Peak Nits: 1000

All my videos are still coming up without HDR when I upload to Youtube. I've waited longer than a week for each one but still no HDR.

How do I record in HDR format for Youtube?
 
Split encoding? If you're not encoding 8k 60fps or 4k 120fps, disable it.

Profile should be Main10. HDR is 10-bit....

Try again or better yet post a log.
