Recording Straight to Hard Drive Workflow
I want to use the IO to capture SDI from a studio camera straight to hard drive. Does anyone have a good workflow for working with footage that has been captured directly to hard drive?
I posed this question on the FCP forum and received the suggestion to break the footage into subclips, then use Media Manager to create a new project with with only the footage required by the subclips. This acheives one of my goals in not having to have the entire shoot on my array. However I don’t see this method allowing a project to be rebuilt and “recaptured” as you would with a tape captured work flow.
Any ideas plug-ins etc. would be appreciated.

You can’t “redigitize” because you are lacking two things. The first, tape, and the second timecode. In my opinion you have three options. #1, run tape in the camera or dockable vtr. 2# capture to the io, edit down to what you need, dump that edit to tape, and redigitize from the edited tape. #3 invest in cheap ata hard drives and a FW to ata bridge, Record to the io (fast raid) and then move the files to a back up cheap ata.
I have captured some green screen footage directly from a sdi out (avoiding the dvcam tape compression) to the io, but I was not able to get timecode to move along with the sdi stream. I ended up transcoding the green screen to photo-jpeg at 100% for the backup, and burned that to 4 or 5 DVD-r discs. Pjpeg at 100% can be 4:4:4 8bit and run at 720×486 at about 2.7MB/s. I have key’d from it before and it is a good backup format.
Hope that helps,

Thanks Adam, it does help. It helps to know that it’s not just something I didn’t figure out. Unfortuneatly it’s not the answer I was hoping for. It does seem like this method of capturing better source would be of interest to a number of people and that FCP should have a deck emulation mode for capturing from hard drive.

you might want to have a look at picture ready (if you need to access whilst recording) or virtual vtr (if you just want to record stuff in) from http://www.gallery.co.uk. They are tools to record files on the Mac.
I’ve only tested vvtr – and then with a decklink and not with an IO – but they may be what you are looking for.
I would say your workflow would be… put the VVTR into record – it will record TC into the QT movie (or should anyway). I’m not sure if you can enter a tape number into VVTR, but you can import the clips into FCP and modify them there – the TC (presumably TOD) should be good as it should be embedded in the QT.
As long as you have video tape back ups that correspond to those timecodes (i.e. stop and start your clips when you stop and start your tape recordings) then you should be able to reconform if necessary.
I do this on the Avid regularly – not that the avid is 100% frame accurate when reconforming anyway.

Presumably, if you can get access to the video signal and the time code that is running somewhere in the studio of the RS-422, you can log in FCP (through the io) and capture later with the tape that is running in the studio. Would that fit your workflow? Not exactly direct to disk, but then all you have to do is feed tapes and capture the logged clips which requires minimal effort.
What kind of studio camera are you trying to capture from, and where does the SDI signal run to/from currently? I need help visualizing your setup. What resolution are you, or do you want to, capture to?
