I'm using a JVC (I think it's HM700 something). I know device manager won't import it. Is there any other way to import the footage and have it stitched together (other than just copying it over).
Is this the camcorder? http://pro.jvc.com/prof/attributes/features.jsp?model_id=MDL101851
We may have to experiment with the files in order to know how to do with it, but when I searched previous topic, maybe this old topic can help: https://www.vegascreativesoftware.info/us/forum/jvc-gy-hm700--74005/
I once helped someone with JVC YUV 422 here: https://www.vegascreativesoftware.info/us/forum/jvc-yuv-4222-wird-nicht-angezeigt--104133/#ca643388
To manually stitch the files: does the traditional command line able to work? I will use other reference on how to merge splitted AVCHD format: https://photography.tutsplus.com/tutorials/3-free-ways-to-join-spanned-avchd-video-files-into-continuous-clips-on-windows--cms-25830
In CMD type "copy /b 00001.mts+00002.mts K:\Merged.mts" replacing the 00000.mts and 00001.mts with the names of your actual files.
Hope helps,

This format is basically Sony XDCAM-EX. I would look into using FFMPEG to re-wrap the files to an .MXF format. Then Vegas will see it as XDCAM. FFMPEG will also concatenate the multiple files too. If you want to upload a short like 3 second clip of the media, I will help with the command line.
If you have FFMPEG loaded on your machine, you can try FFPLAY <mediafilename> and see if it plays it back. If it does, you can convert/re-encode the footage to whatever codec you want in batch. Including converting to Prores if you are one of those people.
