time stamp

Not sure if this is what you want, but here's one way to display your times and temps, though a bit complicated to explain. There may be other more simple ways to do this, but I'll just show you what occurred to me.

First, make an individual slide of each temperature, like this:

Place them in the time line at 1 second duration each.

Then make a timer video clip. To do that go to your iPhone and go to Clock/Stopwatch. Start the screen recording feature and then start the stopwatch. Let run for 11 seconds and then stop the recording. You will then have a screen recording video of the timer running in your iPhone Photos app. Use AirDrop to transfer it to your Mac. You will need to crop it to display just the timer, like this:

You can do the above crop in iMovie by cropping it in the media browser rather than the timeline.

Then overlay with Picture in Picture the timer onto your temperature clips.

Now when you play the timeline each temperature will flash on the screen in succession as the timer runs above it.

You'll need to experiment a little, but basically you need to turn your vertical time/temp chart into a horizontal chart. You can include in your iMovie project a still shot of your time/temp chart to give the viewer an overview.

Here's a good online iMovie tutorial help menu that will explain how to do a crop in the media browser and how to use Picture in Picture to over lay a clip into another.

I'm not sure that I am visualizing correctly what you are trying to do. Can you post a screen shot of your txt/excel file to show what it displays? Is it an animated file where time and temp are actively changing? What end effect to you want?

I have never worked with a txt/excel file before. That format is not listed as an iMovie supported format.

If you can take a screen shot of it then the screen shot would be a supported .png file. Or make a screen recording of it to create a supported .mov file (Command-Shift-5, and chose record from the control box that appears on the bottom of the screen). Then with either of those methods you could import the resulting file into iMovie and overlay it with the Picture in Picture feature.
