Capture Preferences Question

Opticus wrote on 6/3/2010, 2:04 PM
I'm using the HDV capture utility that comes with Vegas to capture HDV. If I click on "Preferences" these adjustments are available:

Maximum RAM Buffer Size (1-to-100%, default is 25%)

MPEG Video Quality (0-to-31, default is 20)

My system captures fine with the default settings, but would I get better video quality by maxing these settings? Will changing these adjustments affect the image quality of my final rendered video (to Blu-Ray disk)?

I can't find any documentation for these adjustments.

Thank you!
Cal

I'm not sure how a quality setting could apply to HDV but it could be for SDI. When you capture SDI you have to encode it. It's a stream.

Not very well labeled, is it?

hi rob,

you capture sdi through the hdv capture app? does that mean you have access to batch capture via tc?

I do not do so personally, no. I had hoped to get access a few months ago to a system with a Xena card to try it out but that didn't pan out. It was being installed on a PPro system and (as is often the case) it didn't work right. So we bailed out of that upgrade.

For some reason we're going to take another dip in that well in a month and I may yet get a chance to try it if my boss is willing to let me put Vegas onto one of the new PPro stations.

If it's a general question then, yes, you use the internal capture app in conjunction with a Xena/Kona or Decklink card. It appears that the capture app will let you import and export log files so you could do batch captures from a log taken at location (or where-ever).


Currently I do batch capture via TC from DV tapes by using Veggie toolkit to import our log files. I have to use my own DSR11 deck because the house DV deck is SDI only. DV just happens to be the format that we've been shooting for the last 10 years for a client who just needs web delivery. For other doc work we've been shooting DVCPro HD (tape).

Honestly, at work I have no need for SDI, but I still hope to test Vegas with it someday soon. I'd like to be able to raise my hand and say I know it works.
