Does anything else other than .mov work? (like WMV?) If so, I would try running the clip through QT Pro after the conversion, and try changing the apeture to clean apeture in movie properties > presentation (This is a long shot).

OK, so if you aren’t interested in accelerated render and export, a suite of real time filters (like Chroma Key and advanced primary & secondary color correction), a broadcast qualityframe-based compressed codec (I-frame MPEG2) with adjustable compression and alpha channel support, MULTI stream native HDV playback and HDV capture window support, you could go for the DeckLink. Otherwise, I’d take a closer look at Axio.
Note however that ATI graphics cards are preferred to Nvidia for use with Axio.

Typically you would use the 1080i (1920×1080)preset for editing progressive footage, since typically it is shot in progressive to impart a “film look” to the footage, and this look is maintained when edited in an interlaced project. Really the only reason to work in a progressive project would be for layback to film, or certain instances involving graphics manipulation. Generally, all distribution, broadcast, DVD, etc. is 1080i (interlaced).
The 1440 x 1080 presets I think are primarily for editing and outputting native HDV.
I’m not sure why Matrox hasn’t included a 1080 30P preset, although it would be a rare circumstance where this would be necessary.
I believe Axio should be able to play back multiple streams of native XDCAM EX (with the appropriate workstation and disk array) on a 1080i (1920×1080) timeline without rendering, whether it was shot 1080i or P; 29.97 fps or 23.98 fps. (I’m not positive, because I don’t have an EX1)

I guess my point is that this should have been a free “point” upgrade. I think there is about as much here as in the PPro 4.1 upgrade (which was free). There is no comparison to the number of features added in the CS3 to CS4 upgrade. Everyone is waiting for the 64-bit “Snow Leopard” release. That would certainly qualify as a full upgrade, but now that looks even further out in the future (another two years maybe). I bet we see 64-bit CS5 on the Mac before 64-bit FCS4.
Apple can make enough money from its user base to afford to put more money into development, but they choose not to. It reminds me of Avid ten years ago, who decided they owned the market, and could get away force feeding users with overpriced software and hardware. It almost put them out of business. Of course Apple won’t go out of business (as long as the iPhone stays hot – maybe a few more years), but they won’t sell the pro apps (which would undoubtably accelerate development), as long as they can get away with charging $300. for what amounts to a point upgrade.

Thanks, Vince,
It turned out to be a corrupted Quicktime DNxHD clip. The wierd thing is that the clip worked for a while, then decided to go south. Other QT clips with the same codec continue to work fine.
Yeah, before I discovered the clip was the problem, I did a complete clean install of the C: drive. Took me four hours. Doh. System’s neat as a pin now, though.

Are you closing the sequences you don’t have an immediate need for? Open sequences are a memory hog, and will slow down load times.

Alex,
Not much time today, but I’m noticing some wierdness when importing clips with transitions (dissolves, dip to black) screwing up the in points on clips copied and pasted into AE. I seem to heve better luck with cuts staying in sync. The timing seems to be within a second or so, so maybe AE has a hard time calculating ins and outs on transition-connected clips?
I’ll check things out more completely later when I have a bit more time.
-
Alex,
So you are saying that the clips that import into AE are offset from the Premiere originals, i.e. different clip in and out points? Does it take the beginning of the clip as the in, or is it random? Is it way off, or is it close?
Are you importing a Premiere project into AE, using Dynamic Link, or copying and pasting between apps?
I don’t think I am having that issue, but let me check it out in the AM. System is currently tied up with an export.
-
Alex,
I’d say either capture your HDV as I-frame MPEG, or convert and replace in Premiere before pasting into AE.
I think AE CS4 is a bit better at handling HDV than CS3, but it still is going to do a better job with frame-based media.
Now that Matrox has come out with their 4.1 beta drivers, which support accelerated export through AME, there is less reason to stick with CS3. I’m liking the added stability and speed of CS4 with 64-bit Vista.
