I’d have to go with David on the latitude. It’s the total key to it. With film, you actually get a better look than video with LESS lighting. If you think of it in f-stops, shooting video is like shooting slide film. NO LATITUDE. You have to be within about a half stop or else you’re going to be clamping or expaning a signal in post, and that means less detail of course.
But with film, you can expose for someone’s face and have a bright sky behind them, and a shadowy corner nearby. Detail will be available in the shadows, and detail will be available in the sky. Whereas on video the sky will be overexposed and have no detail, and the shadows will be too dark with no details. So video requires more lighting. Every thing has to be within an fstop or so of each other. Meaning that everything needs light thrown at it. But then you end up with a very flat, unorganic image.
Maybe someone knows how HD compares to film in terms of latitude. Is it still limited? And if not, why don’t they make some SD CCD chips with the same tech?

August 23, 2005 at 3:42 am in reply to: “preparing video for display” very long render time!I have no idea why it’s so long. Usually this is a 5-15 second annoyance when it starts happening. But the one sure fire cure is to quit moving things around. That is, always do an insert edit or a ripple edit or a ripple delete edit. For example, if you need to move a large chunk of timeline down to make space, don’t highlight all the clips and move them, insert a slug. It will be instantaneous. And when you’re done and you need to move the chunk back to close the remaining gap, mark and in and out and press shift+delete (ripple delete).
So anytime you can avoid picking up someting and moving it, that’s your best bet. You might even be better off cutting and pasting instead of moving with the mouse. If you have to rearrange things, you can do a cut and paste insert.

Are you field rendering in the right order?

Media 100 was simply the video editor for After Effects users. 🙂

August 22, 2005 at 9:41 pm in reply to: DV cam to Final Cut to After Effects workflow questionsCapture the file with final cut. You don’t have to export anything. Simply go to the capture scratch folder (where FCP saved the file obviously) and drag that file into the AE project window. I wouldn’t be messing with DV streams.
If it’s better for organizational purposes to export a portion of the clip from Final Cut, then just export Quicktime movie. It’ll be a reference movie referencing the original media, OR you can check the box that says make self contained and it’ll simply be a copy of the clip you captured, or a copy of the portion you chose to export. Either way make sure your settings are “current settings.”
DV is not an optimal medium for green screen btw, because so much of the compression is in the color info, not the luma info. If you’re planning on doing a lot of this all the time, you’d be better off investing in an uncompressed solution and shooting on something other than DV. Like Digibeta or Betacam.

August 22, 2005 at 1:56 pm in reply to: How do I get “duplicate frame warning bars” (tried the obvious)I run this feature at ALL times. I’m currently on a project and will have up to 10 sequences open, each 5-10 minutes long, sometimes more. There is no difference in performance if I have one open or 10 open, dupe detection on or off. So use your own judgement. I’m only running a G4. Dupe detection does not look for dupes in other seqeunces, but all sequences may be looking at once (which does seem silly programming wise, there’s no reason for a background window to be searching for dupes when it hasn’t changed). So just know that turning on anything in your sequence might slow it down. But I’ve never seen any slowdow with dupe frames. Now if you turn on show waveforms, that’s a different story. I don’t ever turn on waveforms.

I’d set up your editors permissions so that users aren’t a system administrator and can’t update the OS and software. Or install downloaded software either.

August 22, 2005 at 4:37 am in reply to: How do I get “duplicate frame warning bars” (tried the obvious)I think you might be confusing user prefs with sequence settings. If you turn it on in user prefs it’s going to be on for all new sequences. But if you already have a sequence, you’ll need to turn it on in sequence settings or that little spot you found.

And overlays too of course. But I hope this lengthly discussion isn’t just because someone had overlays turned on!
