Best File Formats for Archiving
Hi all,
I am working for a company that is looking for the “best” format in which to save and store its .mov files (final file size and image quality being the most important factors).
For the last year we have been using Apple Pro RES for HD and SD saves. But since Pro Res is a proprietary format I have been asked to look at other more universal “solutions”.
For the SD files I have been recommended DVCPRo50 (which apart for its field order seems OK to me).If you have any thoughts on what I should use for HD (or for SD) please let me know.
Thanks for your time and help,Nathan

Hi nathan,
PhotoJPEG at 75% is 422 and holds better than DVCPro50, while makes smaller files.

Hi Rafael,
Thanks for your quick response,
I don’t know the ¨Photo JPEG process at all so I have some (possibly) naive questions:Are you suggesting the offline rt photo jpeg in final cut? I have tested this and the quality is extremely poor, plus it seems there is a massive loss of resolution (from 720×576 to 320×240). Let me know if i am going wrong somewhere.
Any ides on what File format I should use for HD archiving?Thanks again

Hi Nathan,
Is basically the same codec; the RT is just a vaery-very-low data rate preset.
PhotoJPEG is an scalar codec, at 100% is virtually Uncompress.
PhotoJPEG is the codec used companies like Artbeats for the distribution of their top quality graphics.
Make a test at 75% , you will be amazed.
If you have to archive a lot of stuff in a regular base, you should look a hardware solution to encode high data-rate MPEG-2. I’m sooting MPEG-2 (normally at 100Mbps and the quality is a dream.
50Mbps is the working standard for BBC, Discovery, etc.

IMX30 maybe another codec to look at. It’s 422 but at DV bitrates.
