Recording in camera vs. DAT
Hello Sound Gurus:
We're getting ready to shoot a little feature project on DV (XL2 - PAL) and though I am prone to renting a separate DAT rig and recording off-camera, I want to at least explore the virtues, or lack thereof, of recording it straight onto the tape in the camera. I am always open to being taught the best way. I bow before your expertise and shall retire to read your comments. Thanks David |

Just a couple of thoughts that occur to me, a point in favour of the DAT is the potential ability to record more than 2 tracks of high quality sounds. Most DV cameras can record 2 tracks of 16 bit sound or 4 tracks of lower quality 12 bit sound. Double system sound recording using a multi-track recorder can give you more than just 2 high quality tracks. Recording in camera forces you to mix multiple miked sets on the fly, but keeping the tracks separate in a DAT or a laptop with an audio interface lets you revisit your mix decisions during post. The separate recorder also would give you more options for wild sound. If you're recording a live performance you can keep the recorder rolling even if you have to stop tape in the camera so that you can capture the performance as a unit even though the video consists of multiple shots. The downside of double system is that establishing and maintaining synch is much more fiddly - you need to remember to slate all your shots and unless your camera is sending clock signals to the audio recorder you may need to adjust alignment in post over the course of long'ish scenes if the synch drifts. I'm sure some of the pro's here will have more ideas.

dats record stereo, just like dv cams. they record 16 bit 48khz pcm audio, just like dv cams. there are other vaiables that effect sound (mic preamps, etc,) relative to cameras, but cheap dats don't perform better than good dv cams. for multitrack you'd need something like the new edirol unit (i believe it's r4.) other multitrack field recorders are really expensive although some people use the desktop hard drive multitrack recorders designed for musicians.
i think the best move would be to send the mics to a good field mixer, like the sound devices mixpre, and then send the line level output from that to the line input on the xl2. (i recommend that mixer so often you'd think i'd get a comission.) it's just a really great mixer for the money, wonderful mic pres, better than those on the xl2. it would let someone monitor levels much better than using the camera, and adjust levels withou having to touch the camera.

I as under the impression that 4-track recording on a XL2 would be 12 bit, rather than the preferred 16 bit

Seems at that point then I'd be just as well off taking the whole thing off-camera and into a DAT then, other than having the other as a back-up of sorts and sync reference. Your thoughts, Steve?

If you're recording dialog with one mike, I can't think of a strong case for the DAT. Use a small portable stereo mixer, put the mike on BOTH channels, and record the mono signal 16 bit 48kHz on both ch1 and ch 2 in the XL2, setting one channel at regular level and the other down about -20dB (that way you're covered against unexpected extremely high levels that could distort). OTOH, if you're recording a musical performance where you want very high quality stereo recording or are planning to use multiple microphones for a live event and doing the mix in post, that's another matter and you might consider recording double system, though DAT is not the only choice or even the best choice. As someone else pointed out the other day, multitrack DAT's are expensive! Laptops with an audio interface and multitrack recording software are coming on strong these days, as are direct to hard drive and flashcard recorders. |

Good points. Maybe I should discuss the setup first instead of asknig you to fly blind.
Its going to be a multi-player piece and I will probably be goign wireless at times on at least two, may up to four people. Short of worrying about them stepping all over each other, then I guess the mixer could bring it all into the field mixer on two channels and we should be okay. Music? Not much. A few bar scenes, this is Thailand after all, and maybe even some sadarse Karaoke, but I would probably drop that in during post anyway, except for the inept singer part anf I would record that separate. that being bad might work to my advantage :-) Lot of outdoor stuff on this with traffic no doubt, but that's wht God invented a soudn booth and looping for anyway. |

Sure you're going to need to have multiple mikes? Why not a single mike on a boom and someone who knows what they're doing to point it from just out of frame? An awful lot of features have been and still will be done that way for the forseeable future, wireless whizbangs or no. <grin> |
