“Extra” half lines at top and bottom are completely normal and expected in NTSC; I didn’t think PAL was any different in that regard. Knowing BBC is sticky on the details, I can imagine one getting in trouble for _not_ having them.

That’s the way I see it.
Which again isn’t meant to dis the Io HD. Just a nudge for me that editing on a laptop still hss disadvantages – speaking as someone who edits on a laptop. If you do need to edit ProRes level on a laptop, then Io HD will allow you to do things you otherwise couddn’t.

> and it’s the only solution on the planet that compresses to pro res on board. Since it does this heavy lifting you should have more RT playback of unrendered material because your CPU is NOT doing this decompression to monitor with…
Which gets back at my original question. So from this I assume that FCP is able to mix and modify ProRes media _without_ decompressing them first – is that really possible?
Otherwise the scenario at the top of this page would take place, with the CPU not only decompressing for the effects etc. but doing the extra task of recompressing for the trip to Io HD.
Hope I’m not beating a dead mosquito here, it’s just hard to imagine that ProRes wouldn’t go through this extra compression on output.

That wasn’t entirely correct – there is another solution but I don’t know what it is. Search here or especially in Apple forums on “10.3.9” and “4.5” – there’s a specific tweak outlined. Good luck.

> If you want to archive online, use a codec that’s not tied to any one platform, like animation, targa, photo JPEG, Sheer, image sequences, etc.
I’m interested in this too… for the closes to true archival file storage I can get to (Don’t worry, we’re archiving on tape as well).
My question: which of these formats reliably hangs onto audio tracks, sync, and especially timecode, and is also expected to be generally and easily readable in 10-20 years?
-
If I remember right FCP 4.5 isn’t compatible with OS 10.3.9. You need to downgrade the OS or upgrade FCP. Lots of info on this in the Apple forums.

No, Luke, that’s great. It was just that the specs don’t actually say those formats are available via analog connections. That’s great, thanks!

> I forgot to add the the ProRes codec is in hardware of the IoHD and takes the processing load off of your computer.
But not with RT playback (altered or composited media) if my assumptions are right (see first post). It would require an additional processing step in the computer – recompression to send to the Io HD – compared to a PCI card.
I’m really not trying to put down the Io HD in any way,. Just trying to understand it better.
Thanks for the other details, Jeremy!

Thanks. I guess the answer is that the Io HD is only an advantage for laptops. And I may need that. Just trying to understand if there was some other advantage I wasn’t seeing.

I’m thinking my question wasn’t very well worded. I’m also thinking I’m missing something big here.
Aside from the ability to use with a laptop, what’s the advantage to a ProRes compression pushed through a FW800 pipe, compared to a direct card output of an uncompressed signal?
