From local performances to bigger contests like EuroCosplay, many cosplay performances require you to prerecord your music and dialogue.

Usually it is part of the rules for participation. What is the reason for this requirement? Surely a 'live' dialogue would make the act seem more convincing - rather than cosplayers having to lip sync.

I understand mic's aren't great if you have giant lobster claws or something - but microphones can come pretty small now and could fit in a helmet. Even still, why restrict all cosplayers?

Why does this rule exist?

    The costume can be heavy, moving around in it while talking might result in unclear voice due to heavy breathing. Another reason might be to prevent nervousness. Not all people can speaking in public like nothing. Commented Jun 14, 2016 at 4:43
  • Yeah but it shouldn't be forced because of nervousness. Instead, nervous people should have the choice to have prerecorded audio. Im not convinced that's the reason.

  • If the contest is in a big hall like what i've seen in Supernova Photos it might be so that way the participants don't have to scream out for everyone to hear them

    I think it would allow them to keep schedules better because they'll know exactly how long each act will be.

    It might be enforced so that everyone has the same rules applied. Otherwise, those with great public speaking skill would have the advantage over those without. Commented Jun 14, 2016 at 4:57

It seems that it is a primarily time-management strategy. From the Oyahocon Cosplay Competition rules (bold text mine):

The music and/or prerecorded dialogue must be ready to go as soon as it is put the CD player (this means the participant must edit the music and/or prerecorded dialogue before the convention and put it on a CD). Audio file must be exactly three (3) minutes or less. There are NO exceptions to the rule. If the audio file is longer than three (3) minutes, it will be stopped when time is reached (even if it cuts the performance). Please have files recorded exactly as you wish them to be played.

From Anime Midwest competition rules:

The pre-recorded music/dialogue submitted to the Masquerade staff must be 2 minutes and 30 seconds or less. There will be no exceptions to the "2 Minute" rule, unless you request permission prior to the convention. Any entry over the 2:30 mark will be stopped at that point.

From Anime-Expo Performance competition rules:

Adhere to the 2 minute time limit. MC and video introductions will not count towards the performance time. Audio: Any sound necessary to express your performance (i.e. music, pre-recorded dialogue, sound effects). Must be comparable to a PG rating– no profanity or offensive language. Bleeps or other forms of censoring are acceptable. Should not exceed 2 minutes. Must be MP3 format. Must have minimum 192 bitrate. Try to avoid audio quality defects (audible distortion, overdriven levels, low sample-rate/bitrate).
