Good points Todd. I didn’t mean using the dual-slot feature itself was lame, I do think it’s a great thing to be included with the camera which has all sorts of utilities. What I do find frustrating is the idea that the camera is still so unreliable that it’s asking for trouble if you use it how it’s intended: recording to a CF card. And I agree the problem is probably mostly CF card related, but we do use reputable/expensive media and if more and more people are having this problem, its an issue for Canon too.
Going back to my post above, I was able to retransfer the original card using XF Utility and it worked, which suggests that something in the drag and drop transfer messed up (I was able to recreate the glitches in the transcoding process) which points to Mac OS or the XF codec itself. Regardless of the true problem, I know I’ll be taking a more realist approach and shooting dual-slot in the future as well as backing up using the XF utility. Not a heavy price to pay for outstanding footage, just annoying, and totally worth it in the end.

I’ve recently encountered the same (VERY frustrating and scary) problem. Reshoots are not an option for the project I’m working on.
My details: shooting long (8-20 min) takes with two C300s, 1080/30p, CP1 profile, very fast 90MB/sec CF cards. Upon footage review the next day, I found that many of the clips from a certain session and card are peppered with these hideous glitches. My general workflow up until now has been to drag/drop full card structures to external drive at end of day, use Prelude/AME to transcode to ProRes 29.97 overnight and have a nice set of .movs to review and log in the morning.
After I blew a gasket finding all these glitches, I was also dismayed to not find very much info on the problem. Creative Cow to the rescue! After reading thru a couple of threads (this problem is just now starting to be noticed and discussed it seems), I got a couple of tips. VERY fortunately, I still had the CF cards from the offending shoot and I used XF utility to back them up to my hard drive rather than just drag/drop. The glitches do not appear when previewing footage in XF Utility. Upon a Prelude/AME transcode, the glitches were gone! Whew!!!! This may not work for everyone, but I’d highly recommend using the ‘Backup’ feature in XF Utility
This is a terrible error and I hate having to use a certain software to have error-free footage, but hey, at least I got it error-free. I’ve heard from other users that we should always use dual-slot record when we can with the C300 and I think that’s BS. We didnt pay 14 Grand each to feel nervous shooting to a single card. I got really lucky this time around that I hadnt reformatted yet, I shudder to think about the footage losses many other users may be experiencing.

Yes! Just what I was looking for. Thanks Noah!

Hi everybody, thanks for the tips. To answer some of the inquiries and deepen the mystery, let me add:
– The lastclip.txt is present in both card structures.
– I’m unable to upload the CLIPS folder as my company would strongly prefer to not to have full or partial copies of unreleased footage floating around.
– I have looked at the ShotPut Pro logs and everything is a successful and accurate match/copy.– The BEST part: So I duplicated the cards via ShotPut, found those to have ‘splits’ in FCP L&T, then loaded the cards themselves in L&T and was able to successfully log the clips without any splitting. Then I posted on this board.
When I remounted the duplicated card structures a day later in FCP to recreate the problem, I discovered that the splits were gone and the clips were already labeled and marked as transcoded (full blue dot), even though I had done that with the actual P2 cards and not the duplicated files. So now the problem is not present anymore, it’s almost as if the program just needed to be ‘shown’ the right way with the actual card… sigh. -
Ok, I think I figured out a lot of the above ranting:
Instead of trying to venture off on my own, I wound up retrying the WMV “HDTV high quality” preset with very few modifications and it resulted in a clean export. I still haven’t found out what a 0 Keyframe Rate will do though…
Also, in theory, wouldn’t a 1 KeyFrame Rate result in a larger file than a 5 KFR?

I see, and what container do you recommend? .mov? .avi? .mp4?

Nice, I’ll give it a shot. Thank you!
