hairy_hen said:I'm not sure, when altering the speed for PAL playback, if it's better to do it analogue-style and let the pitch shift upwards, or keep it the same. Probably depends a lot on the quality of what you use to change the speed. Maybe someone more knowledgeable could chime in about that, along with what the best conversion tool to use would be.
A simple "speed-up" (which is basically resampling) is safer.
The more complex pitch-correction algorithms can lead to digital "stepping" artefacts. Someone once suggested Serato Pitch 'n Time was capable of achieving "transparent" results for pitch correction - though it's not much use to the casual user who doesn't have Protools.
