Sorry, I meant Dave and John.

Eric and John,
Thanks again for all your valuable information.
The JVC HM GY100u shoots at a higher bitrate compared to HDV. I believe it’s 35 mbps (XDCAM-Ex in MP4 envelope) which, based on your information, should allow for less “blockiness or blurrines” when transcoding in MPEG2. (I am not using a tripod and I am panning accross a field, albeit slowly, quite often). Again, for Bluray production, I should probably keep the 30p or 60i shooting mode rather than 24p and maybe boost the variable bitrate during rendering and DVDA authoring to match the camera (i.e. up to 35?)

Thank you all. I will have a plenty of opportunities to practice with the 24p setting. I have now rendered a couple of projects shot at 30p to the Bluray template in vegas (1920/1080 60i) and it looks good. The resulting file size is just tiny compared to the uncompressed .avi I tried before ~ 6 GB for 30 min vs. 600 GB). Surprised this much compression doesn’t seem to reduce the quality at least to my naked eye. The Bluray template has 25 bps average bitrate as default. I am curious – does one theoretically gain anything in quality by customizing it to a higher bitrate?

Thanks again

Thank you. I tried it and it looks really nice. Do you think, since my camcorder gives me the option to shoot in 24p, that I should try it and keep the whole workflow in progressive? Will it make any difference in the quality on the BD?
