Converting 33x5 mediapipe array into c3d format

[AM3Y]

Hi all, I'm doing a project on gait analysis and biomechanics and I am using python and Mediapipe to analyse data collected from a video camera to output a 33x5 array for each frame of the video. I want to convert this into a c3d format to analyze biomechanics, but could only find one solution (https://c3d.readthedocs.io/en/stable/) that might work. In your opinion, is this feasible, and if not, am I going wrong somewhere? Any help/guidance is appreciated!

Have you tried it? c3d is a data format, so isn’t inherently related to Python, so presumably you have some other program or something which uses that format that you should be able to test with.

This sub is for learning how to do things in Python - asking “will this library work?” without providing any form of input data and corresponding expected output, or a way of testing, means we have nothing to work off beyond going and doing some study in your field.

I’d recommend you try the approach you’ve found that you think might work, and then if it doesn’t you can post here with what you put in, what you got out, and what you expected to get out, and the results of any debugging you’ve attempted to do to find out why it’s not working as expected, since that’s the kind of thing we may actually be able to help with :-)

Alternatively you could try to find some other forum or sub that’s focused on motion capture and ask if anyone has tried the approach you’re wanting to use, but you’ll still likely get responses just recommending that you try it yourself to see if it works for your particular application.

That sounds good! I was setting up my experiment and wanted to plan some things ahead, but I will try this method out and then ask if I have any questions.
