  • 23.976 NTSC to 720p 23.976 Seq Conforming Issues

    Posted by Jason Gillet on April 11, 2009 at 1:09 pm

    Good Morning,

    I’ve been working on this for about 2 hours already and I thought I had it resloved but I want to make sure I’m doing this right.

    I am conforming a piece in Adrenaline v2.8 that was cut in 23.976 NTSC now it’s being conformed in 720p 23.976. I went through Avid’s help menu found that to do this I had to dupe the sequence then decompose in SD project. Export an ALE of the master clips then conform them in new HD project. Once I’m finished I’m supposed to relink the new media to the originally decomposed Sequence.

    Correct???

    So here’s the big issue. When I do a relink I get this lovely Error: Assertion failed: mob == oldMob File: coreswame compmanMobMan. c, Line: 644
    then it gives me
    An ACCESS_VOLATION exception occurred. For more information see the error log: and location of log file
    it does this twice wile reading the log info then crashes the AVID with this
    Exception: Structured Exception,Exception Code:0xc0000005, ExeptionString: ACCESS_VIOLATION ,FaultAddress: 0x25d50f8, MiniDumpFileName :and name of file.

    It’s early and Saturday and I have today and tomorrow to get this working ANY clue what to do????

    Thanks,

    Jason Gillet

    Jason,

    The normal conform route is to use the modify command to change the sequence to 720P. Then in a 720P project, decompose and capture the new decomposed clips. I don’t understand why you are going to an ALE? Or do you want all the footage in HD to continue cutting?

    Why? Because I actually decided to read the help menu. That’s exactly what they tell you to do. I am going to give the Seq format a try.

    Hi Terence,

    I just went back into the original SD project changed the format then Deecomped the footage in the the HD project. When I go to try and conform I get the 720p/23.976 project format error. I’m going to try the ALE again to see if it works this time. Any other suggestions?

    Now I see the problem, I have never actually done a 720P 23.98 sequence as I have a rule that “friends don’t let friends edit 720P in Avid.” This is from the conform guide and may God have mercy on your soul! 🙁

    Converting a 23.976p NTSC Sequence to 720p/23.976

    Because the source edit rates are different for these formats, you cannot simply change the
    project and sequence format.

    The following sequence is based on source material shot or transferred to 720p/23.976 and edited offline in a 23.976p NTSC project.

    To convert a 23.976p NTSC sequence to 720p/23.976:

    1. In the 23.976p NTSC project, duplicate the final sequence and move it to a new bin.
    2. Decompose the sequence.
    3. Select the master clips and export them as a shot log file.
    4. Create a 720p/23.976p HD project.
    5. Import the shot log file into a bin.
    6. Batch capture the clips.
    7. Open the SD bin containing the duplicated sequence.
    8. Relink the SD sequence to the new HD clips.
    See “Relinking Clips to a New Project Format” in the Help.

    How horrible would it be to get this into a 1080p 23.976 project. Terrance you would love this one. It’s got P2/Red/Varicam/ P2 and Red transferred to tape. I’m not sure what else to do. I can’t get this @*^& to work.

    What are you’re thoughts and what do you think would happen if I try and convert this thing to 1080p and load that way? Will just reformatting the sequence work? What about loading the tape. I guess I’d have to rest the HD-1200A to 1080p 23.976 but will this save may ass in this case? Oh except for the 3 day’s of Metafuse rendering my client has already done. Oh and by the way I’m stepping into this I didn’t suggest ever cutting in 720p. They just kinda went and did it based on recommendations from post facilities.

    Thanks 🙁

    1080 is simple. There you just modify the sequence and decompose and capture. Use the upconvert in the deck to convert to 1080. Life is simple.

    The only catch, is any of the footage still file based? That would be resized on ingest, not Avid’s strong point. I would resize the footage in After Effects, Sorenson or Compressor and convert to DNxHD at the same time so at least the import would be fast.

    Thanks,

    I’m about to get this stuff working in 1080p. One other question the deck which is the 1200A doesn’t convert to 1080p. Will there be a pulldown issue introduced by going 1080i from the HD 1200A (it won’t do 1080p out) to 1080p into Avid.

    And yes there is some file based stuff such as the original P2 material some of which was never dubbed to tape.

    Dud, this is getting more screwed by the minute. Isn’t HD fun?

    You can’t remove pulldown in HD on Avid like you can in SD. Do you have access to a converter, like a mini Terranex or an AJA FS1?

    Anyway I can give you a call? Contact me off list at jason@gilletproductions. PS. Alan M. says your the only one that could probably help me and you don’t like 720p I guess he was right 🙂

  • The 1200A will play out 720p/24 as 1080p/24 just fine, provided you have 24 frame trilevel sync available (it must be fed from an external generator) and set the menus to select 24 as the base frame rate (I’m going on memory here, but I think it’s setting #20, but check the manual to make sure).
