Hi Guys
This is my first time about-to-deal with a replication house. Any thoughts on my 'workflow' below would be really appreciated to produce SD DVDs.
I would like to create the best possible DDP image file possible, for the replication house.
1. Is it an .img file I should be outputting from DVDSP to give to the replication house on a pen drive?
The video contains lots of fast moving, fast edited sports sequences. The original format is Canon XHA1 HDV 1080i PAL (recorded at 50i to play at standard PAL 25fps on VCRs).
The HDV was captured into FCP as standard ProRes422 and edited and rendered entirely in standard ProRes422 and output from FCP as a standard ProRes 422 1920 x 1080 QT File.
Using BitrateCalc I entered 46:33 into Video Length, and selected Type: DVD
2. For DVD I selected 1 x 4.37 DVD5 (am not sure of the capacity of the DVD discs the replication house will be using but 4.37 is pretty common isn't it?
3. Should I maybe ask the replication house what capacity DVD discs they intend to use, and then return to BitrateCalc with my findings?
4. Anyway, with 4.37 DVD5 selected the results are:
Calculated bitrate: 9576 kbit/s
Authoring overhead (2%): 90 MBx
Estimated audio size: 77 MBs
Estimated vide size: 4399 MBs
Estimated size on disc: 4566 M
How might I interpret these figures?
5. Should I also maybe choose a GOP structure setting (Open/Closed, IBBP, IP, IBP, GOP Size)?
As regards a Bitrate Viewer I plan to use this free one (for Mac):
MacDVDBitrateParanoia - Video software and downloads - VideoHelp.com (http://www.videohelp.com/tools/MacDVDBitrateParanoia)
Again, any thoughts whatsoever would be really appreciated.
Warm regards
Peter
