Best capture setting for HDCAM
Hi,
I’m new to HD and was asked to digitize a couple of short films mastered onto HDCAM. I was wondering what are the best capture settings for the Highest resolution possible? Would uncompressed 10-bit pal be suitable for the task?
I’ll be capturing through a BlackMagic Multibridge Extreme from a Sony JH3 Deck.
I know the multibridge is capable of Dual-HD SDI but have no idea whether this improves picture quality, speed or is at all necessary in this instance? also which would be better; 10 or 8 bit?
Any help would be greatly appreciated,
Much Thanks, Matt

The correct answer all depends on your hard drive sub-system. You will not be able to capture 8 or 10-bit uncompressd without dropping frames unless you are running a rather “beefy” raid. If not, then you would want to consider capturing to a compressed format such as DVCProHD or ProRes.

If you have a high speed hard drive array capable of at least 250MB/s sustained speed, you can capture to 10bit Uncompressed High Definition. Better to be over 300MB/s to ensure you don’t drop frames.
The speed of your array is going to determine what you can do.

What’s the best method of finding out your disk speed,
we’re currently working on a Fibre Optic SCSI Raid unit with 1TB, would this be quick enough?
Many Thanks, Matt

is it a SCSI raid or a Fibre Raid?

Run the Disk Speed Utility from BM, it is usually installed on your computer along with the BM drivers.

Thanks for the reply’s, they really helped.
Checked my disk speed and it’s slighty over 260mb/s so probably end up using prores422.
Aside from the best capture, what’s the benefit in using dual-hdSDI from the decklink?
