Help! Clip got corrupted
Have just come back from a shoot and transferred footage across. All fine and worked perfectly on XDCAM Transfer apart from 1 clip. I am getting ‘Failed to Import Movie from file ….’ The clip is greyed out without a thumbnail. It plays fine on the camera and imports fine into Clip browser, but I can’t seem to copy the clip again with new in and out points set.
This was the one clip that I showed straight back to the client on location (as it was the best take). Could that have anything to do with it? Have tried Update media but no change. Running out of ideas, apart from just playing in via SDI.
Thanks for any advice,
Martin.

This happened to me and Sony said to make a copy via SDI or any way you can to another source. It won’t import via Transfer now. After you have it saved somewhere, see if that card will record again over that same area (note the timecode of the corrupt clip) and then you’ll know if it’s a corrupt area on the card. It had nothing to do with playback in my case. It was a corrupt card. I’m still trying to get Sony to replace it… a year later. Good luck.

If it plays back in the camera, then just capture it as it plays back.

Yes, I guesss I was lucky that the clip played back in the camera – I have played out via SDI and got it. However this is only the 2nd job with the EX3 having only just bought it, so am a little nervous now.
Thanks for advice.

We have shot maybe 80-100 hrs on two EX3s and have not had that error…yet.
I have had XDCAM Transfer gray out a clip one minute just to have it pop up
after restarting the application. -
I’ve been shooting with EX cameras for over a year and only had this happen ONCE to one clip. I had more problems with tape cameras in the last 25 years of work—tapeless is a dream come true. You can trust it. But back it up to two hard drives, always, so you can sleep at night. One word…DROBO.

Mr. Clifton is right in that a lot more can go wrong with video tape than with solid state recording. I’ve never had a corrupt clip or been unable to transfer a clip from any of my Sony SxS Pro cards. To be fair, I’ll hazard a guess that some of you have recorded more clips than I have but still………
I also think it’s important to reformat the cards on a regular basis to keep the possibility of directory errors to a minimum. I don’t mean reformat every time but perhaps every 4th or 5th time you empty the cards do a reformat instead of simply deleting clips.
And here’s another thought for everyone’s consideration:
Not too long ago my wife took a still camera refresher course at a local college. Her instructor cautioned everyone against the practice of deleting an unwanted picture from the memory card, saying that he’s seen ghosting of the previous image underneath the new image when the camera takes another shot and it ends up in the same spot as the deleted one. He said to leave the unwanted image as is and reformat the entire card after the images have been transferred to computer. I hadn’t heard of this before and now I’m wondering if the same rules should apply to video as well.

Thanks for your thoughts – it is comforting to think that this was (hopefully!) quite a rare occurance.
I am of the reformatting rather than deletion school. Still early days on the Ex3 for me, but it makes sense to wipe the card clean each time as I have seen on stills cameras that bits of data can be strewn around a card eventually causing access errors.
I’ve been pretty lucky on the tape front over the past 12 years in business, so it all feels a bit lairy at the moment, and the experience the other day was a setback …… anyway, am encouraged by the experiences shared here.
Thanks,

Hi, Martin
I’m new to this forum, but have been following other forums for the EX and your thread caught my eye so I had to join up.
I had this exact same thing happen, but not with a SxS card. I was using a MxR Express Card adapter with a Transcend 16GB class 6 SDHC card. I have 6 of these cards, 2 SxS 16GB and 2 SxS 8GB. I have never had a problem with any of my other cards, either SDHC or SxS. I posted on another forum about this, but no one there had experienced it. Fortunately for me, my take wasn’t a critical one so I didn’t bother to try the SDI out option. My clip would also play back in the camera, and actually downloaded to the drive via Clip Browser, but would not transfer with File Transfer. I got that same error message and grayed out clip. Have you noticed if that clip plays in Clip Browser?
I did try to copy the clip back to another SxS card which failed. Now I wonder if I have a problem with that one card. (no big deal, they only cost $30) I have also heard that the best way to erase the cards is not to format it every time (but there are those who still swear by this) but to use the ‘all clips delete’ function in the camera’s menu. This is what I have always done, and with the exception of that one clip have never had a problem. -
[Derek Reich] “My clip would also play back in the camera, and actually downloaded to the drive via Clip Browser, but would not transfer with File Transfer.”
If the clips plays back in camera and ClipBrowser but XDCAM Transfer can’t rewrap it, it may just be bad metadata (obviously the clip itself is OK since it plays).
I’d suggest removing the MP4 and using the Import function in ClipBrowser. It’ll create a new BPAV folder for it. You can also try importing that orphaned MP4 into XDCAM Transfer by itself. Key is separating it from it’s current BPAV which might have bad metadata.
ClipBrowser 2.5 and XDCAM Transfer 2.9 handle orphaned MP4 well.

Hi, Craig-
Thanks for the suggestion. Since it wasn’t a ‘keeper’ clip, I didn’t really lose any sleep over it. I did follow a suggestion to copy the clip from one slot on the camera to another card, which created a new BPAV folder. However when I tried that, the same result happened. The clip played in the camera and in Clip Browser (w/CRC enabled by the way) but was not recognized by File Transfer. I wasn’t really interested in saving the clip so much as finding a solution should it happen again.
