Deleting all keyframes

What is the best way to delete all keyframes of a stream? Calling KeyframeSuite3()->AEGP_DeleteKeyframe for every key works, but takes quite a bit of time. I was hoping to just virtually toggle the 'stopwatch' button, but I can't seem to find the API for that.

Any ideas?

var targetComp = app.project.activeItem; // Collect the active composition var selectedLayer = targetComp.selectedLayers; // Collect the selected layers var targetParam = selectedLayer[0].transform.position; // Identify the target parameter

// Delete Keyframes forward while (targetParam.numKeys != 0) { // While there are still Keyframes, continue looping targetParam.removeKey(1); // Delete the first Keyframe } // Delete Keyframes backward

for (i = targetParam.numKeys; i != 0; i--) { // Cycle through the Keyframes targetParam.removeKey(i); // Remove the current Keyframe }

I used this script from UserChangedParam and AE crashed. Anyone else having more luck? The script itself works well when run from ESTK.

That's my bad, the script I posted is for ESTK, and it's -slow-

One year later, the idea of doing the deletion backwards helped a lot over here. Thanks!

Hi Roy, Hi Shachar,

I finally got a way:

select the keys (I went the script way, much much easier!) and execute command 21 (delete).

for the record, here's my script (mask outline keys here):

string myScript = "myLayer = activeItem.selectedLayers[0]"; //I call the script on parameter change, so I'm sure the selected layer is mine, do differently if it's not the case!!

myScript.append("myMask = myLayer.Masks.property(");

myScript.append(numConvert(myMaskIndex)); // feed the script with my mask index. NumConvert() is just a way to turn a A_long to a string...

myScript.append(");if (myMask.numKeys){myMask.selected = true;app.executeCommand(21);}"); // check if my mask have keyframes, otherwise it will delete my mask!!

ERR(suites.UtilitySuite5()->AEGP_ExecuteScript( plugID, myScript.c_str(), FALSE, NULL, NULL)); // run the script

Pfffew!! Only 6 years to answer a so simple question for a so usefull function... Programming for AE is fun ;-)

Cheers,

François
