MainConcept: Failed to import a frame!

Hi,

I'm having what seems to be a very unique situation: Google found only three results and those were all for the GH1... so here goes...

I've put around 120 hours on my HMC150 and every now and again the MainConcept transcoder will croak on a clip. I think it's happened a total of 15-20 times or so. It will interrupt the transcode mid-clip with this error:

Failed to import a frame!
Make sure the source media has not been removed

It's sort of a pain because on any given project this will happen a good handful of times (I've gotten two in the last four card dumps). When it happens I say ok, then 'select clips' so it doesn't attempt to retranscode that clip, and start it again. Sometimes it's happened twice per dump.

I can manually transcode the problem clip with the Adobe Media Encoder, it's just a lot slower. I seriously doubt it has to do with the source media being removed, as it will continually fail on the same clip, plus this happened when the source footage was on an internal hard drive.

Any thoughts? Might I have a defective camera?

I've had the same problem. Your solutions match mine (select clips and Adobe Media Encoder). I haven't found what the cause could be yet, but I wondered if it was something to do with the SD cards used, or their speed class. I have all class 4 cards and use 32 GB cards most of the time. So far it hasn't happened on the class 6 card I have that Panasonic sent free with the purchase of the camera (16 GB). My cards are all Kingston cards.

I'll let you know if I figure anything else out, but also will watch this thread hoping someone else has an idea.
 
That's a good point, jpottenger I forgot to mention that.

I have 3x 16GB Patriot cards and one 16GB Transcend. I don't remember which clips came from which cards.

Here is a screenshot of the error:

I got the same error. I have a class 6 memory card, so I don't think its that.
If you go to the "HELP" a pdf will pop up w/ the types of recording setting the software can transcode. Going to try that next.
 
Run it through the AVCHD repair tool by Panasonic. I had several cards that have had a hard time with the MainConcept transcoder and they wrk most of the time when I've put them through the repair tool.
 
Good idea, but no go:

Gotta love the crazy English translation. In my interpretation that says "Sorry, but no errors found"
