Beta Sp to DV
on May 8, 2007 at 6:57:15 pm

I am attempting to archive and clone a large amount of Beta Sp tapes to the digital world.
(Approx 140 tapes)

Other than Digibeta, what would a good cost effective format be.

Obviously, the less compression the better. would DV cam be preferred over dvcpro 50?
I also need to keep the original timecode from the master.

Is there another format I am missing?

thanks

Depends on what you'll be wanting to use the footage for. Personally I'd capture them to a high quality but efficient codec, usually one that will come with your capture card and leave them in just a digital form on some quality external drives.

No more tape, totally non-linear access, playout to whatever format you need...

DVCPro-50 is much better than DV (CAM or otherwise). It's twice the data-rate. Photo J-PEG at 75% is pretty good too. We do some projects that originated on Beta in the DVCPro50 codec and it looks great.

DVCPro50 uses a colour subsampling of 4:2:2, same as PhotoJPEG at 75%. PhotoJPEG at above 75% is 4:4:4, so much better.

But 4:4:4 color sampling translates into huge file size, and it won't be any better
quality when you start with Beta-SP, which isn't 4:4:4. As an analog format it translates
roughly into 3:1:1. Putting it into a 4:4:4 color space doesn't do anything for the quality.

1 30 minute betaSp digitized dvcpro50 equals ? gigs..

DVCPro50 is 50Mbits/second.

Be careful not to confuse bits and bytes (8 bits to each byte)
