hi, thanks for the reply - i have been looking at SDI cards and it seems like these are not cheap things! i thought there might be an easy solution for this but it seems not. I'm quite happy to forget about monitoring the 4 outputs during the composition of the piece and just focus on frame accurate synched playback of the final rendered files. i was looking at ivysync http://montevideo.dyne.org/wiki/IvySync which says it can sync upto 4 mpeg2 files out IvyTV <http://ivtv.sf.net> supported hardware decoders this might be a good solution - i also looked at videowhale which is intended for video walls but a hack could be done by rendering the four videos onto a 2x2 grid.... messy though. i think maybe ivysync maybe a good solution but if anyone can think of a better way i'm all ears :) many thanks rob c > (I have not tried it in a > while).
