Okies, here's a stumper for DSE (It has ME stumped!)

[quade 4]

According to http://en.wikipedia.org/wiki/HDV HDV is 1440x1080 MPEG-2 (The pixel aspect ratio is 1.33 so it displays correctly on 16:9 monitors.)

Taking it into a Mac via FCP for green screen (Keylight actually) compositing in AE.

I take that into FCP with NO conversion and when I look at the property window it says; 1888x1062

No. I'm NOT using the Apple Intermediate Codec yet. I'm looking at the DV25 file in the Capture Scratch created by doing a capture from a Sony HVR-M25U directly into FCP.

Can you explain what's going on here?

Even if the property window in Quicktime was trying to account for a regular 16:9 aspect ratio, it ought to say 1920x1080, but instead it's giving me a totally wierd number. Yes, this is consistant from file to file.

I simply can not correlate this and it just makes no sense.

You lost me at 16:9.

Nice find, but nowhere in the document does it even mention the HDV spec. In fact, the article was written 12/14/99, well before the HDV spec existed.

by your numbers, somewhere you're shifting non-square to square pixels back to nonsquare. Either it's a codec issue, or project setting.
I'm at Adobe training; I'll present this to the AE team tomorrow and see if Bob has any idear of specifics.
The spec is indeed 1440x1080, and AE and FCP will both work with non-square pixels. Are you exporting using Compressor at some point?
Also, how are you getting a DV 25 file? Are you using DV25 offline and then onlining to HDV?
After all is said and done, you also would probably love the CineForm tools, now *finally* available for Apple.
I'll see what i can find. This is not one I know the answer to immediately, I don't edit native HDV in FCP; I use the AIC or Sheer.

Obviously, we don't. Study hard, go to school, win a few awards along the way; you too can look like an idiot. It just takes a little practice.

Nope. It's exactly as I had said. Importing directly from the HDV deck into FCP. No codec change. Nothing. Straight FireWire in.

HDV is "functionally" the same data rate of 25 Mbps via FireWire. Although it's encoded -quite- differently via Mpeg-2.

Again, I'm JUST using FCP to ingest the data from the HDV deck. The intent is to then take the captures into AE (which I can successfully do) but the numbers aren't "perfect" and it bugs me.

Ah ha!

Check out this gem I just got directed to on creative cow. Took the better part of the day, but somebody had the answer!

Glad you found it. I'm still using QT 6.5.2. I installed 7 and found several incompatibilities, so dropped it. I was unaware of the Conform setting, so glad to now know about it.
Good find!
