Random frame glitches on exports, no matter what setting I use it seems...
Hi guys, lately I have been shooting video on my Canon 6D. I have imported it into FCP7, matched the video settings to the sequence, edited without problems but then when I export, it seems no matter what format I export in, I get these broken lines on random frames (I call them glitches). It just feels as if the video is always broken.
The glitches appear on the same frames each time I play the same file back but if I re-export the file, they might appear in a different place.
Sometimes videos I export play fine but rarely.
When I transfer the files to other machines, I still get the same glitches.
My editing machine (mac pro) is getting fairly old now (about 6/7 years) and I've had some services lately due to a couple of other issues but it's working fine in all other areas, so I'm wondering what this problem might be caused by?
Any advice is much appreciated, see the image attached for an example of the glitch. Thanks.
