PAL Speedup is a horrible horrible thing, that is not sufficiently addressed in the Internet video community. In a nutshell, PAL Speedup is when a movie file plays slightly too fast, so it is shorter than it is supposed to be, and all the actor voices are slightly higher pitch than they should be. To some, it is not noticeable, while to others it is maddening. It is such a slight difference that it is right on the edge of human perception. Yet, if you notice it, then you don't like it.PAL Speedup is a nasty side effect from the process of converting film into home video for European audiences. It results in distorted video. It is a widespread problem that is not sufficiently addressed in the Internet video community.

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. == Stop Spreading PAL Garbage! == When you come across a film or video that suffers from the PAL 4% Speedup, you should take all efforts to flag it as "bad" and delete and destroy all copies possible. The archiving of our video art and culture should not be distorted in time and pitch due to the ignorance of video pirates and uneducated encoders. * Know what PAL Speedup is* Know how to detect PAL Speedup* Take action to prevent and destroy distorted PAL Speedup media Video encoded in any format, with any degree of high definition is no good when suffering from PAL Speedup. == Discussion of reversing PAL speedup == {{:Discussion of reversing PAL speedup}}
