Usually for VHS you should use PAL: 704x288 or NTSC: 640x240. The key is to use half vertical size (VHS only have half of vertical anyway), that will save a lot of realtime process and will avoid all interlacing problems (no need to deinterlace later).
VHS horizontal resolution is 240 TVL, or about 320 lines across a scan line. The vertical resolution (number of scan lines) is the same as the respective analog TV standard (625 for PAL or 525 for NTSC; somewhat fewer scan lines are actually visible due to overscan and the VBI).
Przyjmuje się, że dla zachowania jakości obrazu nagranego na kasecie VHS, przy konwersji do formatu cyfrowego należy zastosować rozdzielczość poziomą równą przynajmniej 451 pikseli oraz rozdzielczość pionową wynoszącą 576 (dla PAL B/G lub PAL D/K) lub 480/486 (dla NTSC) pikseli.
- Video Resolution: NTSC: 720 x 480 at 30 fps , PAL: 720 x 756 at 25 fps. - Video Input: One (1) RCA Composite One (1) S-Video. - Audio Input: Left and Right RCA Regulatory.
If your VHS tapes were recorded in LP or SLP, you can probably bump down the horizontal resolution to 640 or even less and see acceptable results. Chroma subsampling is another thing to discuss, however NTSC color resolution is atrocious, so 4:2:0 will be more than adequate.
ntsc-rs is a free, open-source video effect, usable as a standalone application and as an OpenFX and After Effects / Premiere plugin, which accurately emulates analog TV and VHS artifacts. It is written in Rust, and is multithreaded and SIMD-accelerated.
