1) Final Cut Pro and Quicktime Pro will not let you create a video at that frame-rate. Your only chance is to use After Effects – and that may not even work.
2) You need something like this: https://toolfarm.stores.yahoo.net/cineformneohdv.html
3) 1440×1080 is the native resolution for HDV video.

For digibeta to HD you don’t need anything more than the K3.
For BetaSP to HD, it may be worth getting a Teranex Mini for the extra features like noise reduction and better deinterlacing.

[Lauren McGuiness] “I am running a DVI cable (with gender bender) about 100ft to the monitor (Mac 30″) but I am getting no signal at all (totally black screen).”
As everyone said, 100ft. is way too long for DVI/HDMI without any booster. Different video cards will vary on the signal strength. That’s why your old one worked but this didn’t.
I always suggest people try out the $25 HDMI repeater found at monoprice.com – I’m able to run 70ft with it. But… you are using a 30″ so that’s no good. You need dual-link DVI. HDMI adapters won’t work. Yeah, check the Gefen stuff.

It’s a very difficult and annoying thing to do right. I use After Effects because it will tell you how many pixels per second it is scrolling. You gotta do the math and calculate it so that never lands in between any video lines. So for 720×480 NTSC, the titles need to scroll at 240 lines per second, 120, 60, etc. I’m not sure how you would deal with 24p footage. My brain isn’t working well enough right now to figure it out.

Yeah, except Betamax :).
Funny, I thought by the time the format war ended, both would be totally obsolete:

[Jerry Hofmann] “ProRes can’t be monitored externally directly”
That’s not a very accurate characterization. Video codecs can never be “monitored directly” without first being decoded to uncompressed video.
The only reason you would ever see a ProRes video playback option is if you are sending the compressed stream over firewire to an external decoder, like the AJA IOHD – in which case the IO is converting it to uncompressed video. But it does not monitor ProRes directly, as you put it.
Sorry for the snobby technical correction. But I can imagine numerous people mis-interpreting what you said as some sort of deficiency with the MXO and/or ProRes in general – which is not the case.

I don’t think even an 8-core Mac could handle a 14-angle XDCamHD multiclip.
As for recompressing with MM, it should work. Not sure where your errors are coming from. Try outputting a different codec just to troubleshoot. If it works, then there is an issue with the JPEG. If it doesn’t work, then it’s your sequence that is the problem.

There is a device available that will convert LTC into RS-232 timecode. Sorry, but I forget what it’s called or who makes it. It’s been mentioned here on a Cow a few times.

Shoot at a 23.98 framerate. The resolution you choose to go with is trivial compared to the importance of framerate.
If you have a Panasonic camera that only does 720, that’s fine. Many of those cameras only have 800-line CCDs anyways, so shooting in 1080 gives no significant benefit. Again, just shoot in the same framerate. Don’t worry so much about resolution.

Yes, that is well beyond the amount of performance required for ProRes. You can easily edit one stream of Uncompressed HD on that array. Just make sure the block size is 128k for best performance with video.
750GB drives by themselves are almost twice as fast as smaller drives. So your array is probably 200MB/s or faster.
