Thanks! That's what I'm getting from the setup.

Capture source video with VirtualDub, 480i FFV1 Lossless. Process in VirtualDub, Deinterlace with MSU Deinterlacer to 59.94p with H.265 Lossless, MOV container. Commercials are spliced and also upscaled to 4K in DaVinci Resolve, output H.265 MOV then uploaded to YouTube.

The upscale does nothing to improve quality (IMHO), it's merely done to avoid YouTube's horrifically brutal bitrates for SD content. Sometimes I use very mild noise reduction in the audio and/or video depending on the state of the tape.

Just to clarify I meant false claims by Retro RGB not
RayNotes.

... and what are the hardware parts of your workflow?

He does state his capture card, VCR, es15 in the thread I linked to.

JVC HR-S5902U or S5200U both S-VHS

Panasonic DMR-ES15 (for line "TBC")

RetroTINK 2X Pro passthrough for S-Video to HDMI

Magewell USB Gen2 for capture

... then VirtualDub and the rest mentioned above.
