so, i got some old tapes stacked up in the closet with VHS, Hi8 and Video 8 footage. i want to put them on my imac using a A/D converter. (imac i7 quad) ive seen many of them by blackmagic, grassvalley/canopus, elgato and roxio. my budget is around 200. anyone got tips on what to buy/why? and what to look out for? i know alot about digital video. but my knowledge on analog video is minimal. what is the benefit on spending more money on these? the knowledge they give on the website is really minimal. i will be processing the footage in prores 422 on final cut studio. please help me make my decision thanks!
