well, my first thought was "yeah sure", but sadly no just take a realtime stream the frame times will be off a little from your ntp/atomic clock, and for cheap vhs cameras/ players they will be off by alot, your player must adjust the refresh times of the monitor/tv to these timestamps otherwise it will look less then perfect
this is just a matter of syncing to the refresh as the definition of time units, rather than using a pc's rtc or other source. it's a separate issue imo. if you mean that measured physical units would be used in the file captured from interlaced source, imo this is a very bad idea. rather the timebase should be 1001/30000 (or 1/25) with exactly 1 unit increments per frame, and the audio should be sampled to match the video clock. i expect the audio and video clocks already match for digital devices (dv cams, hardware mpeg encoders, ..) anyway this all separate from nut, and applies to any container. rich
