i don't know if i commented. This is good idea. you don't need on-off button if this zoom is used at camera-level since you could get the interlacing mode from asset. And i don't think this should be used on the projector side, since there you could use deinterlacing first anyway. Though mathematically the solution isn't perfect... Acutally it is ok only if you have intralced input, noninterlaced output. If you have interlaced input, interlaced output, and do zoom inbetween, than to make it accurate you should actually use two different y tables depending on the odd/even status of the destination line - therefore actually rendering separate ... but we can forget that for now. :) bey andraz _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
