What I can say is that, when encoding to aac and packing audio&video into an mp4 container, the delay needs to be adjusted for audio and video to stay sync. (aka. Encoder-Priming)
Read https://www.iis.fraunhofer.de/content/da...AES116.pdf for details on why.
Hybrid does this, by adjusting the adjusting the stream delay fields inside the mp4 container during muxing.
Alternative to that you either need to cut or pad the audio (or video) to get back to the initial delay.
Hybrid offers a method using ffmpeg (Config->Input->Decoding->Fix {positive|negative} delays through ffmpeg).
Some muxers even do this automatically and some encoders automatically adjust for this delay and pad or cut the audio directly. For qaac and mp4box some adjustment (audio, video, delay) is necessary to keep the audio/video as sync as it was.
Since I'm not clear on whether you:
a. have a clip that is sync and turns async when processed by Hybrid
and/or
b. you just want the delay field to i.e. say 0
Since you seem to ignore half of the stuff I write and do not care to describe what the issue really is for you, I stop looking into this.
