Tape started but MRC1 didn't at DVinfo.net

Philip Howells · January 28th, 2010, 05:34 AM

My wife and I recently completed our first MRC1 wedding shoot - taking the opportunity to run tape in sync ie with the camlinks on (3 z1+MRC1s).

On reviewing the edit (Liquid 7.2) I discover that one interview, a single continuous shot of about 8 minutes), has failed to be transferred from the MRC1 card. The previous shot has and so has the following. All three were recorded in the same location with the same tripod mounted setup.

Liquid has logged the clip before 0082 and the one following 0083 thus omitting the "missing" clip completely.

Has anyone had such an occurrence? The clip is in the middle of the card/tape and since it was our first shoot with the MRC1s we were taking special care to make sure we followed procedure.

The only thing I can't check (since I have to install a new Firewire 800 card to run the reader) is to check the actual CF card but I wonder if anyone's ever had such a happening? My instinct is to assume operator error but I also like a quiet home life so I'm loath to point a finger in haste.

Philip, can you not replay the CF card from the MCR1 back with your Z1 viewfinder, to check and see whether it has actually been recorded or not?

If the clip is on the card, how did you select the clips for transfer, singularly (is that a word, I mean one at a time) or did you use select all. Could you have missed it. It seems weird that the clips on either side have loaded on to the computer and missed the one in the middle.

If the clip is on the card and it recorded properly...

Are you using the Sony utility to transfer to PC and then importing into Avid? That's the recommended way.

If the clip is not on the card, is it possible someone hit the CamLink button on the unit, and then hit it again? Seems unlikely. If there was a card failure you likely would have had a blinking red light, and it seems unlikely that it would fail and then heal for the following clip. But I suppose anything is possible.

To Peter and Adam, my apologies for not replying - I'm concluding an edit and haven't time to make the tests you suggest. As soon as I can I will. Many thanks for your suggestions and understanding.

It is possible that you shut down the camera while it was still buffering? That will do it.
