For animation, use PhotoJPEG100% or perhaps, given that it’s destined for video PhotoJPEG75%.

24p = 23.98fps progressive video
30p = 29.97fps progressive video
60p = 59.94fps progressive video
60i = 29.97fps interlaced video (or 59.95 fields per second interlaced video)
film = 24fps or 24.00fps to make it clear what you’re saying, when talking also about 23.98fps.I just wish they’d have fixed NTSC back to 30fps rather than 29.97fps with the advent of HD. It would have made archive programs run a little fast, giving you an extra second of adverts too!!

Record time varies depending upon 720p or 1080p and frame rate, and size of card. The camera package ships with 2 * 8GB Cards. See the P2 forum here at the cow for more info.
There are options in the field such as direct to hard disc recording, or dumping to your laptop or a hard drive as you shoot a card.
No, the camera is not for everyone – many people are perfectly happy with HDV, but others are not, and like the frame rate flexibility of the HVX200 and the no tape of P2.
HD XDCAM sounds interesting, but it’s still MPEG2.

[doka15] “So, shooting with these cameras with the intension of transfering to film stock you are still shooting at 23.98? Correct?”
Yes. They shoot at 23.98fps.[doka15] “So during Transfer to film is the Video footage sped up to 24fps from 23.98fps? or is it left at 23.98 and transfered to film that way? “
Yes, it’s sped up from 23.98fps to 24.00fps. The audio is similarly sped up slightly.
They transfer frame for frame, and the audio gets slightly sped up. The reverse is done for transferring film to video.

Drop frame is timecode – it does not refer to frame rate, which for NTSC video is always 29.97fps or 23.98fps. Film is 24.00fps.
You’d not want to shoot 24.00 even if it were available because you’d not be able to display it on your monitor properly.

4:2:2 is compression of sorts (chroma sampling), but that’s not the compression that was being asked about, I think. As for using DVCproHD instead of Uncompressed 8bit – the difference is significant. That said, DVCproHD is worth editing native if you’ve shot that way, but I fear it’s rather too compressed to convert another compressed format to for editing online. Murch was using DVCproHD as an offline codec though, surely?

DVCproHD is 6.7:1 compressed, whereas DV is 5:1 compressed, and HDV about 25:1 or thereabouts ish.
So yes, DVVCproHD is quite highly compressed, but it’s easy to edit compression, and doesn’t take the same generation hit editing native as HDV does.
I find it hard to see compression artifacts in camera footage from the Varicam, say, but if you apply effects, you can start to see the compression artifacts from the original footage, under certain circumstances. But, you’d get similar issues with HDCAM also.
So no, it’s not perfect, but it’s better than HDV.
Let’s hope the HVX200 is a great little camera!

You’ve got to monitor DV properly, back through the deck or camera to see what it’s really like. FCP and mac monitors work in a different colour space etc., so what FCP does is just show you an approximation.

In Film Effects, you get some nice curves too, but they’re limited to nice looking curves only – you can’t bend them to make a real mess like you can in Photoshop. Similarly there are curve options in the levels plugins in Set 1, and they work similarly, but give RGB or Y’CbCr options.

When, say, the DVX10 shoots 24p, the CCD and DSP etc. are all running at 24 frames per second, exactly the same as film – the motion is the same. 3:2 pulldown gets added, just as it would in a telecine, and recorded to tape.
So no, the camera is not still shooting at 60i or 30p. That’s what Sony does and that’s why CF24 on the FX1 or Z1 looks so bad.
