720x480. Downrezzing is always much better than uprezzing. Now if 80% is HDV and 20 % SD, you may get away with uprezzing the SD footage, but only if you deliver on BR. If your delivery is on DVD, make everything SD.
What cameras did you use that deliver 32 bit depth (standard 24 bit plus alpha)?
Thank you Harm for your input. One of the cam is a Sony Handycam DCR SR60. The other one is a Canon HG10 (not sure of the model).
I will deliver on DVD. Downresizing from 1440x1080 to 720x480 is not the same ratio. How do I get it to convert OK?
Should I convert ot QuickTime or AVI? Is there a format more efficient to do multicam editing?
Oops! I meant .M2TS for the AVCHD file format...
I found elsewhere that .AVI would work better. I did it and it worked well. I converted my M2TS file to AVI 720x480, NTSC DV Widescreen. And I used my MPEG original footage as is.
I tested the multicam function and exported the multicam sequence to AVI widescreen without any problem.
Thanks for your help.
