    I just discovered I cannot copy simultaneously multiple keyframes but one at a time.

    Explain. Copying from where to where?

    From a position in time to another one. It works only key by key, but not when you select multiple keys.

    I've had the same issue with Premiere. There might be a way to 'join' them together or group them.

    How are you selecting the keys? I have had no problems as long as I drag-select the keys, ctrl-c and then ctrl-v at the new location or on a new layer. Of course it will plant the furthest left key at the time-pointer location, and it will add whatever the key function or effect is to the layer (if it's not there already). Of course it also has to be a valid effect for whatever layer as well, otherwise it can't paste. I have tried in both CS4 and CS5 versions. Not had an issue. (at least in AE, I don't use PP that much.)

    @dapoopta: Never had such an issue with Premiere. Could you give us more details? I will try and reproduce it.

    @vadervideo: It is about copying keyframes from multiple layers. It is my fault I have not been more clear from the begining.
    For example: you have seven layers and you want to copy and paste all the position keyframes(for all seven layers) from T1 and paste them to T2. You can do it only one layer at a time. You could only vertically drag and select them but copy&paste does not work. It is a hard job, mostly when working with hundreds of layers.

    Weird. I just did some experiments and it works for me (CS4) just as described by vadervideo above. (Drag selecting the keyframes.) What version are you running? Maybe it doesn't work in versions below CS4, but I seem to remember it working correctly in CS3. I tried copying from and to precomps and video layers and it worked perfectly either way. You just control click the layers you want and paste whatever is on your clipboard.

    You can always try to copy the entire effect and paste it to the layers you want that effect on. If the effect is meant to be identical for every keyframe, it works just fine that way too.

    Yes, I understand now - you can only copy keys from one track or layer. You can then paste to several layers at one time by selecting the layers and pasting. But copying from multiple layers and then pasting to multiple layers I don't think will work. I would approach the project differently at that point and replicate the comp and then bring the comps into a new comp type of thing. Make sense?

    Yes, replicating the comp is a good way but sometimes you need a different approach.

    I figured out a way to do exactly what you want to do. I stumbled on it today as I wanted to see if anything could be done - and yes, it can be done the way you need.

    If you want to replicate key frames to multiple layers for any effect and do it in groups, you must do this first:

    Make sure the receiving layers (where you will paste) has all the effects ready on the list. Hence, copy the effects portion of the layer(s) first and paste those first. Don't worry about key frames at this point - the effect list must be there first.

    Now you can select a stack of keyframes from a stack of layers, and paste them into another stack of layers. Make sure your time pointer is at the correct frame (starting frame you want) before pasting into the new layers. This only works provided all the effects are available on each layer. Hence, if one layer is missing a receiving effect keyframe paste, the whole thing will fail. Hope that helps.
