XL2 24p Acquisition (timeline Audio Sync problem)
on Dec 8, 2005 at 2:16:08 am

Shooting on the Canon XL-2 24p mode 2:3:3:2 pull down.

Editing in PPro 1.5 Boxx workstation, dual Xeon Processors. Settings are the pull up for DV playback and 24fps. Under the new Panasonic Presets. Customizing the settings to Playback on a Blackmagic Decklink.

Have tried video for windows and DV Playback.

Everywhere these clips are viewed, the Audio is synced correctly. When viewing in the timeline of PPro, the audio is lagging tremendously. Almost as if, the audio is running at 30fps while video is running at 24fps.

Also, these clips are captured on tape roll and Firestore as well. with the settings on the Firestore at AVI type 2 (24p).

I haven't tried capturing the clips via tape yet. When viewing the avi clip via WMedia player, its fine.

I am assuming its a PPro issue!!

Thanks in advance.

Conclusion:

The issue that I have pin pointed after hours of Tech support from Adobe, Canon and Firestore is this:

There are two modes of 24p (3:2) and (2:3:3:2).

Canon shoots in both modes. Firestore writes an .avi file in only one mode (3:2) and PPro only has settings in one mode (2:3:3:2)

Thus, From Canon to Firestore to FCP works fine. Canon to Firestore to PPro will not work. You have to manually capture the 24p footage direct from Camera.

We looked thoroughly at the properties of both .avi files in one bin and the difference was that the file coming from tape was internally pulled down to a 29.97 rate for editing. The file directly from the firestore still had a frame rate of 23.98, making it unable to edit in a PPro software.

The work arounds were futal as well. Be it exports and re-imports or project settings being manipulate. Nothing in PPro allows you to edit a Firestore data file at 24p (3:2) mode. Firestore will not allow a (2:3:3:2) Mode to be written.

Conclusion for any one who cares is this; until PPro or Firestore get together to support one another's modes, there is no way to use DTE technology in PPro for 24p footage.
