Is it possible to do progressive duration change? 1

Hi, I want to perform a gradual rate change to a clip I am editing. I thought that there might be some kind of key frame facility available in premiere that would enable a gradual rate change across a specific clip, however there appears to be only the option of changing the speed/duration for the entire clip.

Is there any way to do a gradual rate change other than chopping the clip up and altering the rate for each segment?

Hope someone can help!

Cheers!
 
Time remapping (which is what you want) first was added to Premiere with CS3. If you have only an earlier version you are out of luck and reduced to chopping as you suggest.

Pre-Pro Premiere's could take a plug-in from Panopticum Tools that gave time remapping, but I don't know of such a facility for Pre-CS3 PPro.

After Effects, of course, has always had time remapping.
 
Ok, i guess i'm out of luck then! but thats good to know for future. looks like i'm going to have to do the cropping for now. Concerned that the transitions will be too noticeable, but it's the best i can do for now! thanks for your help.
 
Put each chop in a superimposition channel, with a couple frames of progresive transparency on the top channel.

That might help ease your transitions.

But really -- if I understand how time remapping works, there really isn't a transition to avoid -- you just cut and as long as you don't make a jump-cut (which you won't), then it ought to look fine.

Just keep all your frames in order and don't LOSE any of them. 8)

I'm now using a trial version of premiere cs3, but am having trouble getting the time mapping function to work. On the effects panel the toggle effects button for the time remapping is shaded out so that i am unable to use the key frame function. I swear it was accessable when i first tried it, now it is constantly unavailable. Am i doing something wrong?

Also when i did get it to work earlier it did not change the linked audio, but instead unlinked the two leaving the audio channel unchanged. Again is there something amiss here?!
 
Ok nice one, will check it out. Unfortunate that it doesnt also apply to the audio channel simultaneously. Cheers!
 
If you want to remap the time on your audio, then you're razoring it on the timeline, or using something like Goldwave to do the shifting you want.

Be careful with your crossfading so that there is no obvious volume shift. If you can keep your crossfades smooth, then no one will know the difference.

A "trick" is to not worry about doing a big complicated multi-channel crossfade. Figure two shifts, and bring in some sort of "slowing down" sound effect, some sort of whooshing sound. Then, you only really need to do two changes, and people will take the whoosing sound as your latter audio, diminished.

You can only slow audio down so much before it's all just rumbly growly crap anyway. No need to knock yourself out if at this slow of a speed, your dialogue is indistinguishable from Eric Cartman screaming in German.
