A: To preserve scientific accuracy. An MP4 compresses pixels and loses precision. A JDR file retains millimeter-accurate jaw position data to 0.01mm. The manufacturer assumes you will view it only within their ecosystem. Conclusion: The Real Workflow To summarize: You cannot
If you are looking to simply play a video file, check the file extension again. Did you mean M4V (iTunes video) or 3GPP (mobile video)? If your file ends in .jdr , it is almost certainly a medical jaw tracking file, not a video.
Inside the software, open the .jdr file. You will likely see a 3D model of a jaw moving, or a graph plotting muscle activity versus jaw position. Adjust the view to "Slow Motion" or "Full Screen."
OBS will save an .mp4 file to your Videos folder. Use a free tool like LosslessCut or the built-in Windows Photos editor to trim the beginning and end.
