The Lanczos method isn't worth it. You're trying to shrink images to 720p and then compress, which usually reduces quality significantly compared to the benefits of choosing Lanczos over Bicubic. It's more efficient to opt for a less demanding resizing technique so the encoder can handle frames better and maintain higher quality.
Choose Bicubic instead. Only Bilinear resizing makes sense if you're reducing 1920x1080 to 960x540—then the process becomes very simple, discarding every other pixel. Resizing algorithms become noticeable when dealing with fractional values like 1.5 for 1080p to 720p.
Pick a profile; if none is selected, it might default to the baseline, limiting encoder performance at 720p. Main profile is usually sufficient for 720p and won’t offer major gains if you go high, though it uses more CPU. For streaming at 1080p with enough bandwidth, higher settings could be justified.
You might also adjust settings in the custom text field to fine-tune between presets—like adding --rc-lookahead 15 with the --faster preset to improve performance.
Be sure you're capturing in NV12 Full Color Range and using 709 color space to avoid extra conversions, which can tax the CPU.
Also, verify your upload speed: you mentioned 14 Mbps, but are you experiencing any issues?
It seems everything is working well with minimal issues, just reducing the bitrate if needed. For tuning, I'll try bicubic. Regarding the monitor output for 240Hz, you can choose RGB, I444, i420, or NV12—what's best for you?
