<big>* PAL video encoded frame rate 25fps from film or NTSC source* People sound a little bit "chipmunk" (high pitch) and the film plays faster than intended* Results from outdated source to digital processing and/or sloppy/ignorant job encoding</big>Exception: If a video is from original European production, such as a television program produced in the UK and is already PAL, the frame rate will be 25 fps source to 25 fps digital. In this event a digital video file of 25fps will not have any speedup, since the source was already 25 fps. When checking a video frame rate know that the mere fact it is 25 fps does not necessarily mean that it will be higher pitch and shorter duration. To verify PAL Speedup, you must know what the correct playtime is and compare that to the playtime of the file. Such exception cases represent the small minority of PAL video files you will encounter, most suffer from PAL speedup. == Discussion of reversing PAL speedup == {{:Discussion of reversing PAL speedup}}
