Added frames in CS6

When I import a 25FPS avi into CS, then the timeline stays at 30fps. CS seems to add frames to create 30fps. When I finally produce the new video at 25fps, the added frames are still there.

Am I mistaken that it seems that CS converts the 25fps to 30fps and then converts the (internal) 30fps to 25fps?

It seems so to me. This is a real problem. The added frames are there in the produced output video, this means that some of the original frames have gone out the window somehow.

Sorry for the late reply. I did some checking in CS6, and I can confirm that your results are correct.

The timeline runs at 30fps. All edits are at 30fps. All sources are up-sampled to 30fps before the edits are applied. When you produce, you choose a desired production frame rate, and the timeline is down-sampled to your production frame rate.

The problem seems to be that the upsampling and downsampling do not add/remove the same frames. You're the first one to notice this. I will open a bug so that we can address this in a future release.

You can prevent the upsampling by using source videos at 30fps. You can prevent the downsampling by producing at 30fps.
