    Consistency Check Failure

    I'm getting a Consistency Check Failure warning button on a fully editied and otherwise good working sequence - it is preventing me from exporting or mixing down - any ideas how to turn off the check? The footage otherwise looks fine and I can't see where the problem lies, or what to do - the problem wasn't there when I cut the stuff, only showing up now, and not always on rendered footge, so I can't blame that.... the footage is mixed EX cam 1080 p 25 and HDV 1080i all edited on a 1080p 25 timeline using DNXHD 120 MXF, standard raster.

     

    Everything looked fine until just now when getting ready to do a mixdown prior to exporting it final FX and DVD....

    Re: Consistency Check Failure

    if I advance out of the frame that hangs it up, yes. Otherwise, it hangs at a seemingly random frame... - when viewed on a frame by frame basis, I see no visual errors with the image

    Random frames of the very same clip? If so redigitize it.

    Re: Consistency Check Failure

    if you mean recapture, that is a problem - this was all on tapless media, and those media are since reused. If you mean rerender, I can do that...

    Re: Consistency Check Failure

    If You cannot reimport the original file try a videomixdown of the clip, and use that instead, but it may or may not work.

    Re: Consistency Check Failure

    I was experiencing the exact problem and found that a mixdown, consolidate or even a transcode would fix the problem. I wasn't comfortable deleting the original clips, so I didn't but... I DID find a way to locate the offending frame/s.

    When I was doing the mixdown/consolidate, I found that the mixdown or consolidate would hang up during the export process... I was unable identify the frame that was causing the issue, since it was playing within the time line itself. Long and short of it is, I found the problem using the failed mixdown. Just put it on the timeline on an added track, it pointed right too the problem, just like bread crums. Find it, kill it, redig if you have too, or cut it all together if you don't have the source.

    Re: Consistency Check Failure

    My good ness! This project wrapped so long ago i forgot about that problem. But no doubt it will surface in the future again, so thanks Kev! great idea, sensible way to attack the problem.

    Re: Consistency Check Failure

    i;m sorry if this sounds amateur but could you give me more detailed instructions on how to do this? when you say kill it do you literally mean remove that single frame from the timeline? i just don't get what the process is you outline here.

     

    thanks in advance.

    Re: Consistency Check Failure

    I am in the same boat as borys.t.


    I'm experiencing the same issue, but don't understand what the posters are recommending.


    Detailed steps would be very helpful. :-)

    borys.t:

    Since Kev signed up to post that answer and hasn't been back it's unlikely that he will elaborate.  I can only guess, but it suggests to me that he just removes that frame.  It would be better to recapture or re-import that entire clip and replace it if you can.

    An alternative technique that most people use to track these errors down is the "divide and conquer" approach.  Split your timeline in half, and find which half has the faulty media.  Split the faulty half in half again and repeat the process until you track down to the faulty clip.

    Obviously you can use the same technique inside that clip to find the individual bad frame(s), but it's usually simpler just to recapture.

    It should be obvious anyway, but before you do anything to your master sequence make sure you have a copy.

    Re: Consistency Check Failure

    Hi

    We have had this error many times.  There is quite a bit about it in the Media Composer Macintosh forum too.

    Over there (on the dark side - joking) they felt it was due to attached USB drives having some clips or renders on them.  One other poster also thought old unsupported versions of Avid FX plug ins were to blame.  Nothing conclusively resolved it for some of them and for us.  We still get it following all the advice in this forum and the Macintosh forum.  Got it last week on our latest project. 

    I confess we have both USB drives attached (although make sure they are NOT referenced in the Media Creation/render settings) and we have an old version of Avid FX (unsupported and I am hoping to upgrade production suite soon).  But we tried the project with the USB's detached and uninstalling old Avid FX (on same project it still re-occurred).

    Our error occurs on Canon 5D Mark ii files imported from AMA linked clips then consolidated to import the files as DNxHD codec.  It does not occur if we import the clips the old way with the import command and wait for them to import.  It occurs on dissolves and it is the same frame every time - deleting frames just moved the problem for us to the first frame after the cut - so we gave this up - also its not cool to remove frames in the middle of a dissolve - you get a different error - related to insufficient clip length for the dissolve, etc.  When we get the error, we exit MC 5.5 (yes it occurs on the later versions) - reboot the computer and then we can re-enter MC and send the clip to QT reference.  Another work around is to use export and render the clip in MC as an MP4 (takes ages) and then you can re-code the clip in Sorensen or whatever (you will lose some quality this way). 

    A couple of points -

    1. We mistakingly chose DNxHD 10 bit for the codec on the import - really, really worsened the problem.  But it still occurs with the (is it) 8 bit codec.

    2. If we remove the dissolves - no problem - clip sends to QT Ref perfectly.  That is the problem is in the rendered effect - not the source clip.  Although once it occurs in the clip on the timeline if we send that clip from the bin to the monitor it occurs playing the clip back in the monitor (ie: there is no render in the source clips its fresh from the bin) - not the time line.  Weird ?- we thought so.

    3. Re-importing, consolidating, transcoding, re-render in to out - none of these fixed it.

    4. We have (as mentioned) upgraded to 5.5 hoping it went away - we have also gone to Windows 7 Service Pack 1 - unsupported and let Windows Update the Nvidia Quadro Driver to the latest (unsupported version) - still have the problem.  BUT I will note our playback of AMA files is wonderful - best it's ever been - smooth and real time - render resolution set to low or yellow.

    5. This problem does not occur on MC 5.01 it was introduced I think from 5.03 on-wards.  If you roll your system back you may find the same thing.

    6. The problem is really, really bad if you mix clip resolutions on the time-line - ie: we used Canon 7D 60 fps 720p files on a time line with 5D 24fps 1080p files and the error occurred all over the place even where there were no dissolves.  That project became unmanageable.

    7. Finally we have an 'unsupported' system - ie: a DIY build following VideoGuys DIY 7 project - http://www.videoguys.com/Guide/C/DIY+Systems/Videoguys+DIY++Intel+Core+i7/0xe07f65920351fbf3ed8f9892355dfda0.aspx so there maybe issues with the main-board chip-set.  But others with this flavor workstation are not complaining so its maybe our old Avid FX (but we're not doing without it) or our RAM memory (which was not a matched 6 set but a 3 + 3), or something else we haven't stumbled on.

    PS:  Win 7 SP1 and the latest Nvidia Quadro driver (unsupported) really decreased FX render times by like 2/3s and the AMA playback is now wonderful.
