Sound is recorded in a separate file in a separate folder on the card, called “audio”. Real-time sound is captured. If you play back the clip at a different timebase (i.e., a slow-mo clip) then the audio is ignored. However, that audio is still available on the card and you can bring it in and manipulate it however you want to.

[Mark Shepherd] “if I could “print to tape” from a NLE system (FCP) in the DVCPRO HD format back to the P2 card in the Panasonic HVX200″
I am 90% certain that that can be done. Not 100% sure, but 90%…

[Scott Pictures] “What about archiving. I was thinking if I used the 4GB P2 card I could burn the contents to a data DVD in case of hard drive failure, ect.
A DVD makes a very cheap archive for a 4gb card, and preserves all the metadata.
[Scott Pictures] I can’t afford the $21,000 Deck otherwise I would just archive the P2 card to tape.”
You wouldn’t want to do that anyway. The $21,000 deck is probably the worst way to archive. You don’t want to go archiving to video tape… if you want to archive to tape, instead archive to DATA tape. It’s far less expensive, way faster, and signficantly better.If you archive to video tape, you lose all the metadata, and you turn all your individual video files on disk back into clips on tape, which would then need to be re-digitized. Forget that, instead use a DLT or SAIT or LTO data tape drive. It’ll archive all the metadata and keep the clip-based nature of the project, so no redigitizing necessary! Quantum has a new MXF-aware drive that knows all about MXF file wrappers, can output the files at 3x real time (288 megabits per second), and can restore individual files or even individual clips within files (i.e., you have a minute-long clip, but only want the middle 10 seconds? It can go out and find those 10 seconds, unwrap the stored MXF, extract the 10 seconds, and re-wrap it in an MXF file for direct import into your NLE.) The Quantum drive isn’t cheap, it’s $10,000, but it’s still less than half the cost of the videotape deck, three times faster, and the per-gig cost is much less too: $100 for 300gb, vs. $100 for about 90gb with videotape.
Data tape is the way to go, if you want tape. Blu-ray burners will be on the market soon, for around $1000 you should be able to back up 50gb of data on a dual-layer disc sometime around March or April, right? Don’t remember exactly…

[toke lahti] “If panny wouldn’t lowered the price there would have been cf-p2-adaptors on sale very soon and then panny wouldn’t have sold very many p2 cards.”
I’d buy one of those. I don’t think Panasonic intends to sell very many P2 cards anyway — two or three per camera, max. It’s not a disposable media, so you don’t need a lot.

[Paul Shard] “I wondered since it is “bus-powered” via the firewire connection would that mean the HVX200 would be powering it and basically acting as a computer to control the download? If so that sounds like a VERY COOL camera!”
The HVX doesn’t supply any bus power, so you’d have to supply power some other way. However, the rest of what you say is true — the HVX does act as a computer to control the download, it can format a drive and write a card’s contents to the drive and also verify the card’s contents to make sure that they were accurately copied to the drive.

[Brian Cutts] “I’m not sure that you can mix the formats on a P2 card”
I’ll guarantee you it works. I’ve shot a clip in every format the camera shoots, on the same card, just to try it out. Everything from 1080/60i down to DV 24p, and everything inbetween.

[NICK B] “Yes but you still need to be able to edit in DVCPRO 100HD first.”
Yeah, but that’s not hard. I’ve seen it done on a two-year-old Mac Powerbook G4 1.33ghz, off the internal laptop drive.—————–

[toke lahti] “So, in p2 mode tape drive doesn’t exist, but in tape mode p2 do exist?
Can you transfer material from tape to p2 when in tape mode?”No, it’s one or the other. You can’t transfer from tape to P2.

Well, simply put, the HVX does almost everything the Z1 does, and lots and lots of things that the Z1 doesn’t. The HVX produces sharper footage in 1080/60i, with better sensitivity and way more latitude. Its footage looks substantially better than the Z1’s.
Unique selling points for the Z1: it’s switchable 50i & 60i, and it records on tape, and can get an hour of HDV-caliber footage on a $5 tape.
Unique selling points for the HVX: it’s got a better focus assist, a true manual zoom, a less-cluttered LCD and viewfinder, it uses real DVCPRO-HD recording, it has four channels of uncompressed audio, frame-discrete compression, it can record true progressive scan in 1080/24p and 1080/30p, it also supports true progressive scan in 720/60p and about a dozen variable framerates in 720p, it also has near-DigiBeta-caliber recording in the excellent DVCPRO50 mode, and its focus assist system is way better than the Sony’s and can be used while recording (which the Sony cannot do).
They’re not in the same class, other than at price. HDV is not DVCPRO-HD, and never will be. It’s quite amazing for what it is, but it just isn’t as good as DVCPRO-HD (and don’t just take my word for it, take Canon’s): Canon makes the HDV XLH1, but when it came time to shoot expensive footage to demo their own camera, did they record it on their own HDV format? No, they sure didn’t. They instead went out and rented (or bought) a $30,000 DVCPRO-HD deck, and piped out the HD-SDI signal to that deck! Yes, you heard that right — Canon wouldn’t even use their own HDV format, they instead used Panasonic’s DVCPRO-HD format, and paid extra to do that. The exact same format, the exact same codec that the HVX records natively. And at DV Expo, Canon dubbed their HDV footage over to DVCPRO-HD and used that to play back the footage in their booth. They didn’t show any footage from HDV at all, they showed it all from DVCPRO-HD. So, what does that tell you?

[Ron Shook] “I ask if it is possible while shooting PVCProHD and/or DVCPro50 to record to miniDV tape a downconverted DV25 backup?”
Not possible. There’s a physical switch that reboots the camera into either tape mode, or P2 mode. When in P2 mode, the tape drive doesn’t even appear to exist to the camera. You can’t even eject the tape when in P2 mode! So no, no simultaneous recording possible.
