Doing a video capture is not a dump. That's the point. A dump of analog data should be representative of the original analog medium, which in this case is an electrical video signal. A Rec. 601 translation is not a dump of the data. It is a conversion to a modern format, and it is not reversible. Rec. 601 filters and samples the signal, which is exactly what we will have to do, but it also demodulates the signal and applies a comb filter, which, primarily for flexibility, is something we should do digitally with shaders.
It's similar to why I don't consider samples to be adequate in place of discrete audio. We need to get as 'close to the source' as practical. Sampling the video signal is certainly practical (admittedly expensive, though only one person needs to do it). If the direct laser thing turns out to be practical (and reliable) we should do that instead.
