Apart the obvious things (better source media and player, better cables etc.) I’d like to explore some different approaches:
average/median multiple capture (using the same media/player)
I tried several times, and it works really well – it delete noise and dropouts NOT present in the media/player
average/median multiple capture (using different media/player)
usually it delete noise and dropouts ALSO if present in the media/player
it improves the quality of tape based media – like VHS or Video8
hardware Comb Filter
it improves the quality of composite based media – like VHS or Laserdisc
it deletes completely any dot crawl in theory – never found the working way in real life, though… anyone who is aware of how to make it work, please post the info here, thanks!
found here – it seems it works well (apart the change in color)… further investigations and tests are needed!
