Oops, interesting is the right word alright, I got it wrong. I divided 1Meg (1,000,000) by (13*2), when it should have been by approx (13000*2). So it is actually only 38 clip's thumbanils that could be transfered per 1meg of data transfer. I'll try and be a bit more accurate as I make my next estimate :-) If we assume that we are editing a 30 minute show, with 1 clip every second (an purposefully overestimate), we will hav 30*60 = 1800 clips, which adds up to approximately 45 meg of thumbnails. I still think that we can get away with using either files or pipes - it will be rare that so many thumbnails will need to be generated, and it is not possible for them to all need to be generated simultaneously - they wouldn't fit on the screen :-) Cheers, Jason -- Jason Wood Homepage : www.uchian.pwp.blueyonder.co.uk
