Yes, is it especially so if you have just performed a AE project saves?

If you separate your video footage to another hard disk, you will notice that that hard disk will be very busy.

I have tested in on Mac AE CS4 and it is exactly the same.

Thanks Dave,

The strange thing is that AE is responsive throughout the edit until we do a project Saves. After the project is saved, there are no disk activities until you click on the timeline. Once that happened, the data hard disks will go busy, and the mouse pointer will turn into a rotating disk. The only thing you can do from then on is to wait – a good 5 minutes if your project is huge.

I brought the project to a friend’s Mac (mine is PC)and the exact same thing happened! I think this is AE CS4 specific as one of the older project from AE CS3 did not exhibit the behaviour until bringing it into AE CS4.

September 8, 2009 at 9:33 am in reply to: Frame rate issue

We have similar issue:

Video was rendered using AE CS4 (v9.0.2) in QT (v7.6.2) at 23.976 fps.

When re-imported into AE, the footage was correctly interpreted as 23.976. However, when this clip was rendered out again (from 23.976 comp), the end result is such that there are 24 physical frames a second but many frames were skipped (by repetition). Therefore, you have a 23.976 fps video but with a motion effect of half that frame rate.

This can be solved by opening up the initially rendered file in QuickTime, and re-export using QuickTime. Only then if you re-import the footage into AE CS4 that the render will be correct.

You can continue working on square pixel aspect ratio in PS.

Do activate “Aspect Ratio Correction” button in AE comp window so you can see your graphics as intended on PAL TV. However, keep in mind what you will be seeing after the “correction” will not be pixel-to-pixel accurate.

Hi Eda,

I believe there is only one way to capture HDV (directly) right now, and that is using IEEE1394 (Firewire/iLINK).

SDI will only carry ITU601 (720 X 486) and HD-SDI at 1920 X 1080.

Note that you have stated yourself that the SDI is “down converted” and that is from 1920 X 1080 to 720 X 486.

And no, using the current and new HD J series with IEEE1394 wouldn’t do either. That model’s IEEE1394 only output DV and not HDV.
