user10755: I filmed a short interview with 2 cameras. one shots in 25 fps and the other in 30 fps. When I open the sequence in Premiere I have to choose one frame rate and then one of the clips is out of sync.
I use the sound only from one camera and have problems with the sync. 
How can I fix this?
Thanks
Jonathan

user3908: The surest way to make this work is to convert one set of material so the two have matching frame rates. No frame rate conversion is perfect, but moving from 25 to 30 is more likely to look better because no frames need to be dropped. Instead you'll get interpolated or repeated frames. Be sure that your "30 fps" is really 30.00 and not 29.97 before you start. Premiere should tell you, but you can also use MediaInfo or other standalone tool
If Premiere can do rate conversion use it; otherwise try ffmpeg or similar.

user1950: Premiere should be able to deal with source material that has different frame rates in the same sequence.
In your project window, right click the footage and choose Modify>Interpret Footage.  
 
In the dialogue that appears you should be able to specify a frame rate for the material. If this is set correctly Premiere will interpolate the footage to match the frame rate of any sequence it is cut into, without slowing it down or speeding it up, so theoretically the sound should stay in sync. In the best of all possible worlds, that is.
