Keyframe conundrum

gjesion wrote on 2/26/2009, 8:12 AM
I've been a user since version 5 and I have yet to figure this out. I have 2 separate clips on the time line. I wish to keyframe some pan/crop movements on the first clip. I open pan/crop click on the 'Sync Cursor' button and the keyframes are created where expected. On the second clip I wish to change the pan/crop without creating keyframes. (E.g. setting the framing on an element that may not be in frame at the start of the clip.) I click on the 'Sync Cursor' button to disable it and I still get keyframes! I close pan/crop - open it again, checking that the 'Sync Cursor' button is not enabled and still get keyframes! Anyone else seen this behavior? Is there a sure fire way to enable-disable 'Sync Cursor' and have the disable take effect immediately? This issue only comes up once in a while, but is a real pain when it does.

As a workaround I let it create a keyframe and move it back to the start of the clip, but would prefer not to have to resort to this.

Jerry

P.S. I used pan/crop as an example, but this issue exists for any keyframable effect.

Jerry, I think all 'Sync Cursor' does is synchronize the timeline cursor and the P/C cusor. Disabling the Sync Cursor does not (AFAIK) disable the creation of keyframes.

If I am understanding correctly what you are trying to do, try this. When you want to put a P/C keyframe at the beginning of an event, with focus on the P/C window press the home key. That will put you at the beginning of the event (or timeline if you are using the track P/C).

Jerry,
I just did a test. I disabled the sync cursor and exited Vegas. I re-ran Vegas and now when I make a move in P/C I do not get a keyframe at the current position in the clip. I guess what I am really after is to apply the keyframe to the whole clip when I have the P/C window anywhere on the clip.

It's a bug.
If you enable or disable Sync to Cursor it does not take effect until you close and reopen the dialogue box. Pretty simple workaround once you know what's happening, very frustfarting when you don't.

Bob,
Even that doesn't work for me. I even opened P/C on another clip and it still was creating keyframes when I made P/C changes with the sync cursor not selected.

You can get into that state. If you have already added a keyframe to a P/C it's always stuck. You cannot clear keyframes by changing state and it's VERY easy to get a extra keyframe at frame 1.

Try this test.
New project. Drop gen media onto a track. Open PC on event, do NOT do anything in PC dialogue apart from change state of PC, close PC dialogue. Open PC dialogue, it should now behave as you've told it to.

EDIT: Important to note that the change of state for the dialogue is global, it affects ALL PC dialogues.

EDIT2: One other thing to keep in mind is disabling sync to cursor does not stop you from writing keyframes. If you move the PC T/L cursor anywhere other than frame 0 and change PC it will write a keyframe regardless. What disabling sync does is to disconnet the PC cursor from the main T/L cursor, that's all it does.

Ah! The light goes on! I can get the result that I want by disabling cursor sync (making sure that it "takes"), put the timeline cursor to the section of the clip that I want to frame, make sure the cursor in the P/C dialog is at the start of the clip, and watch the preview window to make any P/C (or other fx) changes. Excellent! Thanks for the help Bob.
