JPEG to master HD
Just wondering. Given that HD uncompressed really takes up disk space, and needs that much bandwidth. How much worse does Photo-JPEG or the new Motion-JPEG really turn out for HD mastering?
I’m wondering using these for long-form mastering so I can use systems with ‘lesser’ hard drives rather than tax the RAID systems.FCP Editor, Mumbai, India.

Hi Neil,
On the Mac platform, PhotoJPEG capture uses a lot less disk space than DVCPRO HD but it’s quality is set to 25% so you mind find it a little soft. DVCPRO HD will give give you better results than PhotoJPEG on the Mac. The PhotoJPEG codec is full resolution (1920 x 1080) whereas DVCPRO HD is only 1440 x 1080 for PAL countries. DeckLink scales DVCPRO HD for output at 1920 x 1080
On Windows, Motion JPEG is an excellent codec if you have to work in a compressed format. It is full resolution 1920 x 1080.
Given you are on the Mac platform, I would recommend you experiment with both PhotoJPEG and DVCPRO HD but I think you’ll prefer DVCPRO HD.

Hi Luke – What are the dangers, if any, in changing the P-JPG capture quality from 25% to 50% or 75%. Obviously there’s a filesize hit. I can’t test this for myself as I don’t have a HD card yet, but have been wondering about using P-JPG for online.
Thanks in advance.
