    Hi,
    I'm trying to create a track etc, for FocalLength.
    Via: op->FindTrack, InsertTrack, etc.
    But How do I find the (descID) needed.
    Could it be something like descID = DescID(DescLevel(ID_CAMERA_ZOOM,0,0) ?
    Thanks.

    Usually, you can use the description resource (like Ocamera.res) to get at the description ID definitions. You might also want to set the CAMERA_APERTURE along with this.

    In this case, the second DescLevel() exists because I use a generic track/sequence/key creation function. Like this track code section, where id = CAMERA_FOCUS and sid = 0:

      
         // Find Object Track by id/sid  
         if (!(track = obj->FindTrack(DescID(DescLevel(id), DescLevel(sid, DTYPE_REAL, 0)))))  
         {  
              if (!(track = AllocValueTrack(obj, DescID(DescLevel(id), DescLevel(sid, DTYPE_REAL, 0))))) return ErrorException::Throw(GeLoadString(ERROR_MEMORY_TEXT), "CreateKeys.track");  
              obj->InsertTrackLast(track);  
              doc->AddUndo(UNDO_NEW, track);  
         }

    Wauw, thanks Robert, its working allright.
    I'm recording position and rotation tracks with a similar generic function.
    Strange thing is: replay position tracks seems a heavy load.
    Deleting the recorded position tracks (HPB) on the fly, immediatly causes a jump up in framespeed. (no matter display quality).
    As said I use the same function for recording tracks
