You could export directly to FLV with Perian (https://perian.org/#download). It will integrate FLV and many other omitted formats to your Quicktime. In FCP, under Export using Quicktime Conversion, you’ll have the choice to export to FLV.

SSD’s as system drives are not a bad idea at all. The Windows-gamer-son-in-law scores a point there. The WGSIL does lose that point he just scored by forgetting eSATA and suggesting FW800 though.
SSD’s do have speed issues if you’re constantly writing to and clearing the same blocks, which is why they’re a bad idea as media drives, but as system drives they rock. Especially if the boss is footing the bill. It’ll get even better once Apple are bothered to implement TRIM support so their OS actually works as it should with their hardware (/rant). Even when an SSD gets to the block-rewrite cycle and slows down, it’s still faster than a platter drive.
System drive speed is not something that makes you go “Wow!” with a new computer, but it’s never lost. If the computer is ordered and everything, I’d just smile and roll with it. Anything else would be like waking up to find a Porsche GT3 in your driveway and wondering where your Hyundai went.

Your hard drive is not fast enough. You don’t give details on the video you’re trying to edit, but I can hardly think of an HD codec that would work for editing off your 5400rpm system drive.

Thanks for filling my gaps, Mark.
Wait… that didn’t come out right…

I’ll jump into the debate with three words: Audio Ease Speakerphone.
If, during a mix, you want a sound to come out of any kind of speaker, in any kind of room with any kind of background ambiance, this should be the first stop, IMO. You can construct your own chain in a few minutes and the variations are endless. You can even virtually rotate your mics. And the booth stays clean.
This is probably overkill for the OP (500$), but one of the best investments an audio post mixer can make.

Hi Shaun,
Welcome to the fun fun world of pro audio interfacing! You need to do a Dolby-E layback to get your 5.1 to HDCam. That will encode your 5.1 as 2 channels. Those two channels can not be listened to directly, as they now transport data, not sound. You need a Dolby-E decoder to get your full sound back. The normal procedure (with the place I send stuff to at least) is to lay back the Dolby-E to channels 3 and 4, with your stereo mix on channels 1 and 2.
If you’re a student, Dolby-E may be out of your reach, as many pro post houses don’t even have it. Another solution would be to lay down your Lt/Rt mix on two tracks of the HDCam. The Lt/Rt can be converted back to LCRS (not 5.1) by a ProLogic audio decoder. If you go down this road, still include a true stereo mix (Lo/Ro) on the other two tracks of the HDCam. I hate going the Lt/Rt road because the decoded signal is so flat and narrow compared to the full Dolby Digital. The best solution would be to lay back to HDCam-SR, if at all possible.
If you’re now interested in the necessary tools, https://www.neyrinck.com is a good place to start. I personally do both Dolby-E and Lt/Rt with a combination of Neyrinck, Waves 360 bundle and a hardware Dolby DMU.

Do you have Perian installed on your system? If so, FLV should be an export option in QT. I don’t know how reliable it is but it could be worth a look. ffMPEGx also does FLV.

Hi David,
Bit depth has nothing to do with sync. Sample rate does, though. Your two sources were maybe recorded at different SR, probably 44.1k and 48k, and imported into the same session without SR conversion? That’s a classic mistake everyone has done at least once. The solution would be ensuring your two sound files are of the same sample rate and convert whichever one doesn’t match your editing project.
If things are “completely out of sync”, it’s probably SRs, but recording sync audio to mp3 is a no-no, especially if the recorder does real-time mp3 conversion. The conversion process can affect sync, but the effect is pretty minimal. This is probably not your problem.
In most serious audio work, 32-bit audio is frowned on (except if you’re a Cakewalk user). 32 is a bigger number than 24 or 16, but that doesn’t make it better. I won’t go into full-integer vs floating-point calculations, but 24-bit/48kHz is the standard most sound-for-picture is recorded to and edited at. Recording directly to your editing format will bypass conversions that can introduce artifacts and smudge sync. These last two points are probably not the source of your drifting, but things to look out for in the future.

The version of the QT application you open shouldn’t have any influence on the QT ressources FCP relies on. Do not delete QTX itself, of course, that would create a mayhem. Just open QT7 instead.

QT7 should be in your Applications/Utilities folder. You just have to “pro it” with your license code. And put it in your dock. And trash any shortcut to QuickTime X (which sounds way cooler than “10”).
