We never run into this issue in our narrative work because realistically a LONG take is maybe 5 minutes. I hear my audio guy talk about it however.

That's a fatuous argument. It depends on the amount of time remapping and the level of MP3 compression. For example, it's not difficult to apply too much time stretch/compression resulting in completely unrecognisable audio.

Unless something dramatic has changed with time compression/expansion software in the few days since I used it last, I really don't need to try it. I've been using time compression/expansion software by Serato, WaveMechanics, Melodyne, Waves and DigiDesign for over a dozen years, you think I'll "be impressed" by trying it again?

That's a coincidence, in the UK we not so lovingly call filmmakers who don't care that their sound is distorted or out of sync "Wankers" (a colloquialism for masturbater), small world!!

I'm not saying that drift problems are incurable. Using time compression/expansion software, along with other editing tools and methods, this problem can be solved but it's usually tricky, time consuming and doesn't give particularly accurate results. It's certainly a potentially serious problem to consider if the OP is thinking of hacking his/her DSLR to provide more than 12mins continuous recording time.

After 5 mins you are certainly getting drift but it's probably too small an amount to be noticeable. I can understand why your audio guy talks about it though. It might make an interesting test, if you've got nothing better to do one day: Leave the camera recording for 12 mins and use a clapper board every 10 secs or so, then import the video (and sound) into your NLE and see how much drift you're getting. At least you'll know if the drift is noticeable within the 12min limit and if so, at what point it becomes noticeable.

He hits it because he records live music venue stuff as well. The feed from the board will invariably drift from the camera and also drift from the room mics if they are running to different recorders.

As someone else has mentioned, the 12min limit is more of a tax issue than anything else, though the newer DSLRs are coming out with 29.59 minute limits.

If you are not shooting events such as a concert or play then there is really no reason to be going to the 12min limit.

The only way around the limit that I have had work for me is to have more than one camera and stagger the start of the recording. During events that also works best since you dont want to always have the same angle and you would be cutting to different cameras anyways.
