CS3 interprets my HDV pixels diferently..
Hi,
I’ve just got CS3 up and running on my intel mac.
I’ve opened up a AE7 project using stills and HDV footage and woah…all my HDV footage has gone back to a 4:3 aspect ratio.
I realise this has to do with PAR, but why is AE CS3 interpreting my footage differently?
e.g. in AE7 the project window tells me my HDV footage is 1920×1080
opening the same project in CS3 it tells me it’s 1440×1080.
Because my comps use still images with square PAR as well as HDV it’s a little distressing as my alignments are all skewiff.
Thanks for any help.Bruce

HDV 1080 *is* 1440×1080 with a PAR of 1.33.
It’s final aspect is equivalent to 1920×1080, but it’s not really 1920×1080.
AE is doing the right thing. You only need to turn on the PAR correction preview button in Comp panel.
There’s no problem in bringing a 1920×1080 still image with square pixels into an HDV comp. AE will do the right thing automatically.Adolfo Rozenfeld

Thanks.
Yes, I understand what you are saying.
The problem is that AE CS3 is interpreting the HDV footage differently from how AE7 does.
(So if CS3 is doing the right thing, then AE 7 was possibly doing the wrong thing?)Basically, in AE7 when I drag a 1.33PAR HDV clip into a PAR 1.33 comp, the clip is the correct 16:9 AR.
Then, pening the same project in CS3 I find the HDV clip has changed to a 3:4 AR although it still has a PAR of 1.33, as does the comp.
I have to change the PAR of the comp to square pixels for it to look 16:9.
But this in turn pushes all my jpgs out to the edges and destroys my design. in some comps I’ve used only Jpgs. These are fine.As I mentioned, the project window in AE7 says the HDV footage is 1920×1080 (1.33). But in CS3 the identical project says it’s 1440×1080 (1.33). there in lies the problem.

AE7 was “wrong” and AE CS3 is “right”.
However, if being right means breaking your AE7 project, then it’s wrong again 🙂
It’s worth noting that even though HDV is HDV (duh), there are different ways to “wrap it” and thus it could provide wrong interpretation details.The question is: are you using the final, release version or the public preview?

I’m using the paid for, out of the box version.
It just means I need to finish this other project in AE7 so not the end of the world I guess.
Thanks. -

I remember another user had a similar problem in the very last days of the Public Preview stage (when CS3 8.00 was already done). So, the issue will be investigated and hopefully there will be a fix if needed.Adolfo Rozenfeld

Finally! Adobe fixed the HDV interpretation bug in AE 7!
After Effects CS3 correctly interprets HDV footage as 1440×1080 (1.33) which means scaling and other operations doesn’t introduce unnecessary and unwanted artifacts. If you’ve been used to 1920×1080 HDV in AE 7, you’ll need to unlearn the wrong way of doing things.
