Strange problem with Canon GL-1
As the subject states, I have a Canon GL-1 [Insert ‘dang, time to upgrade’ comments here]. I have developed an unusual problem, which I believe is related to the heads/tape. I am not switching tapestock (I use TDK 60 min miniDV tapes). I place a tape in the deck, and load it up like normal. But when I review the footage, 3 things occur:
1) there is a black, sometimes with green band running vertically on the left edge of each frame. It takes up less than an eighth of the frame. It often has macroblocks of these colors that extend into the image a small amount as well. As the footage is played back in the camcorder, the band and blocks do move around some, but in a random pattern, occasionally pixellating the entire frame.
2) I cannot dump the footage onto the computer. No NLE I use (Vegas 8 Pro, Premiere Pro CS3) can capture anything at all. No running capture timecode, nothing.
3)No sound is captured on the tape (that I can find). None on playback inside the camcorder, and I can’t dump the footage to find audio on the computer.
Cleaning tapes do nothing, and I took it to the local high-end A/V repair shop (a very reputable company), and they found nothing wrong at all. The only thing that can occasionally fix it is if I review the tape, see bad footage, eject the tape, put it back in, record a few seconds of footage, and review it again. Repeating this cycle seems to sometimes fix the problem, but lately, it’s been almost every tape I use. Luckily a Firestore in syncro-slave mode saved my backside yesterday on a shoot. I have a Photoshopped example frame of what’s happening, so I can email it to you if you like.
Ideas?
