Timed meta data/MP4/ID3 lost after encoding

[my]

Sir ,

We are the leading streaming company in india currently we want use your ffmpeg tool to convert videos from single bit to multibit

While doing that we are facing some issues which i have described below.

We are using metadatainjection module provided by wowza to inject metadata(timed event/ID3/ text event) in live stream .While doing live streaming we record that same video.

When we open recorded video in Hex editor we see that meta data.
which we injected , I am attaching the media file and hex editor screenshot with this.

Open the mp4 file attached in hexedior and search for word slide
you will find it

Now if try to convert this mp4 video to lower bitrate it removes all the metadata injected during event.

Is there any way by which we can convert this video to lower bit rate without loosing this meta data ?
