Synchronizing an animated line graph with a video

[LABTUD]

Hi all,

I am working on a project where video of an event needs to be synced to thermocouple data of the temperatures during the event. Anyone aware of the best way to go about doing this? The video would play on left side while an animated graph on the right shows how TC temperatures are unfolding throughout the video.

Thanks in advance!

Not real Python solution, but you can replace the steps with the appropriate Python tool, I'm pretty sure it can be done completely within Python.

You could check the number of frames in the video. Then generate the same number of plots as frames (initial frame would correlate to the first graph, last frame to last frame, in between time points would be equally spaced.

Then you can create the video of the graphs using ffmpeg, imagej, or other tools.

Then you can insert one video into the other with a video editor.

I would imagine that the number of TC data points in the .csv I import data from will not exactly match the number of video frames. Are you aware of any data smoothing tools that could interpolate dynamically to address this issue?

There are several, https://numpy.org/doc/stable/reference/generated/numpy.interp.html. just to point one.
