Nest Video retrieved from Google Takeout does not have timestamp data

I have downloaded nest video via Google Takeout. The video does not seem to include timestamp information. I saw in other support groups that you need to activate subtitles in the media player but all the players I have tried, they ask to identify a subtitle file that does not seem to be provided/offered in the Google Takeout Download I received.

I think this is different than when you download a video clip in the Nest App. This is when you download all video information via Google Takeout

Any ideas? This is for an important legal issue and the timestamp information is critical.
