Software for Stitching Video clips from SD card

I want to use my V2 as a wildlife camera recording continuously to the SD card unconnected to WiFi. Seems to work OK but as we know the recording is in the form of 1 minute clips. I have tried MP4Joiner and it sort of works but I am not sure if it could turn clips into large (1 hour +) files. My ideal would be software to merge or concatenate the 1 minute clips into large files that could then be processed by something like DVR-Scan to break out clips that have motion in them. Also with MP4joiner the results have some odd artifacts like recursion (not sure that’s the correct term but it is like the clip backs up a couple frames and plays again.)

I think these little cameras would be great for this as they can capture a couple days (or more on lower resolution) powered by a big battery and are cheap enough to just switch out a new one while processing the video from the old one.

Has anybody done this in a way that is not a PITA and if so what softwares are you using to accomplish it.

Thanks

Cross platform VLC Media Player will play back the clips as one stream (but not join them). On Windows, Windows Media player can join them. On macOS, Quicktime Player can join them. People also report using ffmpeg, but that requires some technical knowledge and tinkering I believe.
