  • Workflow and HD field order

    Posted by Michael Sacci on April 4, 2006 at 5:14 pm

    I’m editing my first HD project and wanted to double check my workflow with people that may have done this before. (I think this is what Walter B suggested)

    Footage shoot on HDCAM 1080i 29.97
    I have rented a Sony H-J3 to capture via Kona 3
    Because of the amount of footage (8 shows – 6 cameras – 60 minutes) and the desire to edit in HD I’m converting to DVCProHD 1080i

    Edit in FCP

    When done make a Self-contained Ref Movie DVCProHD codec and take that to a place that can print to DigiBeta deck. Right now the client wants the show delivered on DBeta for broadcast. NTSC

    Any RED flags?

    Now the one other question is my capture presets from AJA have the footage as Upper field first is that correct? What happens when I go to DBeta or DVD? (I’m testing to DVD now)

    This all looks good bujt you could actually bring the D-Beta deck in house and do all of your downconverted outputs to d-beta throught the K-3.

    What are your plans for color correction when going to SD?

    The HD and SD colorspace is different and you really should think about doing a HD to SD downconvert using media manager, then color correct the SD footage in the SD colorspace.

    You COULD do this.

    Media manage the final timeline to SD ten bit uncompressed and then do all of your color correction, etc, render that as a final output.

    Save your HD sequences for recapture at a later date if they ever want an HD master.

    David,

    Very good point and I have had that in the back of my mind. How will the downconvert with Media Manager compare with downconvert via the Kona card.

    Also the client is only paying for a general color correction and not a scene by scene, so we are just evening it out. My video shader in the truck was awesome so we are really close to begin with. I just need to make sure that there is not a issue with it not being broadcast safe. Plus I think we need to letterbox the video going to DBeta tape since it is for braodcast.

    I don’t have a DBeta record deck and sometimes it is cheaper to take a HD to a place that does and just have them lay it off.

    I’m not sure about others, but I’ve found some field jitter issues with HD converting to SD. I bring the finished HD reference (or full QT) movie into After Effects, interpret footage to upper field, then do a new SD comp and re-size it to fit. Then, I render it lower field. It seems to be a pretty good recipe for ensuring the field order is correct.

    Compressor will do a nice job of this too because it has the optical flow engine from Shake built into it. The best thing to do is test a few clip and come up with somethiing that works weel for your footage. You can also to your scale and Crop if you set up the right preset. Just test it.
