I know I'm a little late to this thread, but I recently got an Ojocam Pro (same as the Mini 0801). On the latest firmware 20140404, the camera produces .MOV files which end up fairly easy to join together if you have a recent Mac and an old, OLD version of Quicktime 7 Pro. To get it, basically you go and download Quicktime 7 Player from Apple's website and then buy the Pro version for $20 to activate the editing features.
Once in there, you can assemble multiple files together by opening them each up in separate windows, then use the "jump to end" button on the bottom of the screen to cut and paste each segment together. Make sure you actually "Select All" on each segment and use the "copy" and "paste" feature. Do not use Edit->Add to Movie; it will look like it plays back fine but the ability to export the movie without re-encoding will not be available to you.
Once your movie looks the way you want, Go to File->Export
Then choose "Movie to MP-4" then click the Options button on the right.
File Format: MP4
Video tab:
Video Format: Pass through
Leave the rest of the options alone, click the Save button on the previous page.
The key is the Video Format: Pass through - this will make sure that Quicktime does not attempt to re-encode your video. It will be very quick for it to produce the output video.
The final video will be a seamless continuous video in a single file. Took me an hour or two to figure out this combination, hopefully this works for someone!
I know the folks at Ojocam are working on a Mac version of their viewer, but I couldn't get the "merge" function to work. That will be the ideal solution, since it can then handle the GPS data too.
