Video mistiming in Captivate published file

I have trimmd an mp4 in Quicktime to cut the beginning of the video. Saved the file as an mp4 and inserted into Captivate as Slide video on the first slide. I have sorted the video timing so it is spread over 7 slides and when previewing as HTML it works fine. 

When I publish it the section I've trimmed in Quicktime is suddenly there at the beginning of the video while the audio for the video starts at the trimmed point as it should, meaning the video and audio is out of sync and the whole thing a complete mess!

Does anyone have any suggestions?

I have played the mp4 video in Quicktime and the piece I trimmed at the beginning is definitely not there so I don't understand how it can be reappearing?

I'm using Captivate 2019 on Mac OS 10.13.

Thanks!

Re-encode the video in Adobe Media Encoder.

 

It is not a good idea to put a video on the first slide, but will not expand on that.

That's great. It has worked thank goodness.

Didn't know about not putting video on the first slide. 

Thanks very much Lilybiri!

It is not documented anywhere, but something I learned since output needs to be HTML5: avoid a heavy first slide, just use a simple title slide, no audio, no video. Due to the much longer loading time, and the fact that video and audio is loaded On Enter for each slide. Same logic to leave a small gap for slide audio.
