    Exception: Failed to setup a sample provider

    Hello,

     

    I am at my wits end trying to finish a show and the clock is ticking.

    We are just starting a annual series I do and as I have been going through teh first episode I noticed AVid started to get very sluggish. Suddenly it got to the point where Media Composer would just hang and I would have to force quit.

    I though the problem was from using some 4K DNxHR footage and flexing it down to 1080. I prerendered those as 1080 DNxHD files and replaced the footage. Everything seemed good and then it started to get sluggish again.

    It got to the point that if I had all 3 layers of video (Layer 1 - Main content/Layer 2 - Watermark/ Layer 3 fonts or graphics) MC would hang. I read about using the PL key so I mapped that to my keyboard and it worked great! Or so I thought. That let me get to the end of my editing but now as I try ot export the show I get this error

     

    Exception: Failed to setup a sample provider!

     

    I have no clue where to go now but I need to get there quick! Any help is much appreciated.

     

    Cheers,

    John Barata

    I havent seen that error before.   what kind of a graphics card do you have?  

    Usually sluggish behavior occurs when their is either a timeout happening or the activity on the Mac is being tested.  Is the application manager open?  If so, close it.  Also can you pen the activity montior and provide any insight into what if anythg is hogging the system?

    Also, it is possible that the media is on a device that is not fast enough to support it.  Many usb2 card readers (for p2 cards, or for dslr cards) are not tested for throughput, so that could be a cause. To resolve this Copy the structure of the card  to a folder on an internal hard drive, then AMA link to it again.   Does that chang the behavior?

    Corrupt media. Corrupt  media can also cause this behavior.  Try to AMA linking to different media of the same format, and see if the issue is limited to just one Card (corrupt or damaged card), or just one shooting day (bad camera firmware). 

    Also see if you can eliminate the error with only 2 layers...  report back

    Re: Exception: Failed to setup a sample provider

    Thnkas Marianna,

     

    I found the culprit and it was a watermark that I was using in my show. A simple .png overlay. Once I deleted that everything was better. Or so I thought!! I just openned up another project which I had finished a few weeks ago but teh client asked for some extra exports and I can't open any of the timeline because i keep getting teh same error. All my media has been copied over to my Lacie 8big 24TB raid.I just did a speed test and I'm getting write speeds of high 700's and read speed just under 1000 MB/s so I don't think that would be the issue.

     

    I'm going to try to quit the application manager and see if that helps. The corrupt media made sense in the last video but it would be odd to have that again in this project.

     

    Any other insight?

    I just looked at the activity monitor and MC is of course at the top and then AvidOpFrameGeneratorApp is next and quicktimeOpServer is not responding. Not sure if any of this means anything

    Re: Exception: Failed to setup a sample provider

    Yep that was the one. I started rendering off sections of the time line until the error returned and then would shrink the area and try rendering again until I was able to pin point a corrupted file I had. When it started to happen again a little later I disconnected all drives from computer except my raid. (I had a few projects on teh go and had 4 SUB drives hooked up at the time) Once I disconected them everything seemed to be OK again and it's been working fine since

    Are these files linked or Avid media?

    Re: Exception: Failed to setup a sample provider

    I get this error message transcoding Canon 5D mk iii footage to DNxHR LB.

    Funny thing is, it transcoded two clips well, all other 300 clips will give me that error.
