I'm currently waiting for my HPX and HVX Book to arrive, and I just picked up the 170 today. Fooled around with it a bit, loving it so far.
Few questions:

1) 720PN, is it pretty much the most standard to shoot in for 720 on this camera?

2) The manual says when I'm going 720PN and changing my framerate (I think other than 30 or 24) , that audio isn't recorded unless playback and recording are set to the same frame rate. Does this mean if I want to shoot a music video in 720PN I can't shoot it at 36 FPS and have audio? I will have to shoot in 720P to get audio? How easily do 720P and 720PN work in a timeline together?

What are some basic beginner tips to using this camera, good things to know? I'm comfortable with the DVX but skipped the HVX and this is pretty much new. I'm loving everything so far, but I could really use some tips and tricks, or things that maybe a new guy wouldn't catch right away in the wonderful world of P2 and HD.
 
Yes you are correct, you can't shoot 720 PN at an overcranked or undercranked speed (depending on what you're frame rate is) and get audio simultaneously. I would suggest capturing all your audio with a field recording device, and hire an audio mixer so that you can concentrate on your camera work.

However, this still won't fix the problem that the audio will play back at normal speed and the footage will be slow motion. Back in the day, audio was recorded onto tape, and playing it back slower was possible. But with digital, slow audio playback just sounds bad to me, but I've seen some people get it pretty close.

As far as tips and tricks go: get Barry's HVX/HPX book. I think there may be a DVD as well, and if so, it would be in your best interest to get one.

Hope this helps. Enjoy your new cam!

You can shot at 720/24p at 60 frames per second (no pN) and then slow the footage in post.

So I can shoot any frame rate in 720P and have audio? I would be shooting at 36 FPS with my music playing at 150% speed for the musician to sing to, then slowing it down together in post.
Will I have problems throwing 720P and 720PN together on the same timeline?
 
or, if you are shooting a music video, will you really need sound ?
You probably won't shoot the whole thing slow mo (will ya ?)
So, every time you start your music, sync it (at least approximatively) with a clap and mark it in your camera report.
Then on Final cut (or any other) re-sync it and lip sync it.
or at least that's what Ill doo next week for my shooting.


Otherwise, I still don't quite understand the Hi speed P (not PN) system ...
What would be great if anyone could give us his own way of doing that kind of thing ...

Having a stretched/distorted/unpleasant sound is not a problem for my music video as I will replace the whole sound track wit the album version.

The idea is to take your songs audio, then speed it up then export to a device that will playback. Then have your singer sing along to the faster song (at an equivalent higher frame rate, 150% or whatever of what it would normally be), then when you bring it onto your PC and play back at your normal project framerate, the audio will be fairly similiar to the songs normal playback speed but your singer is moving a bit slower and smoother. It just gives it a really nice look, but obviously its not used for the whole video. Also having audio working just makes it easier to line things up a bit then no audio at all.
 
Another question here.

So I open Final Cut Pro and it asked to setup my device. I specified it as DVCPRO HD, and my sequence and capture presets are both set to 720P.
Now I'm in my project, and I've captured both 720PN footage and 1080P footage into my project. The 1080P footage shows up with a frame size of 1280x1024. This is normal for the HPX170 because of how it creates the actual 1920x1080 frame, correct?

What problems will I get capturing 1080P footage with the 720p preset? Do you have to capture 1080p and 720p footage seperately?
Or does the capture preset not matter that much?

DVCPRO 1080 should be 1280x1080 with a 1.5 pixel aspect ratio.

Log and transfer should be entirely independent of your sequence settings.

But will I mess things up if I use a 720P capture preset, and also capture 1080? Or do I need to leave the Log and Transfer, then change my capture preset to 1080 (which setting? 1080i/60?), and then capture again?
