Aimersoft enlarges video from 19mb to 101mb

[vmars316]

Hello & Thanks:
Changing the pitch of a (19mb) music video .mp4 :
Using AimersoftVideo, Audacity,
no matter how I do it (strip audio 1st, or strip video 1st)
once Aimersoft gets hold of the video, it enlarges video from 19mb to 101mb.

Is there a better way (more efficient way to do this) ?

Thanks..vm

Maybe fix your audio and then remux with MP4Box / YAMB?

I've never used Aimersoft, but it sounds like a configuration issue. Nothing should be altered by simply demuxing and remuxing, unless the app is configured to do so.
