converting files made by older iMovie version

I've been trying for some time to offload several tapes which were made by an old Digital-8 camera I have onto a Mac. In the past, I've tried this with a G5, but the FireWire adapters (the camera uses the original cable) made the process unstable and unreliable. I have recently found and resurrected an old blue/white G3, 233mHz, and with iMovie 1.01 installed successfully imported one segment to attempt editing and placement on a DVD on a 2014 iMac running 11.5 and iMovie 13. When transferred (thumb drive), the raw imported files show up as "Unix Executable files" and are not importable into iMovie 13. When I made a movie on the G3 out of the individual clips in that segment and exported it as a MOV file, they show up the same way. My thought is that I'm going to have to find an older Mac running a version of OS X in the OS9-OSX overlap period and convert them to the version of iMovie on that machine, then try importing them into 13. Is that feasible, or is there another, better way? There are some videos on there that are very important to us in a nostalgic way.

Hi rehjaeger,


Thanks for contacting Apple Support Communities!


We understand how important it is that you can access the movies you had saved on your previous Mac.


Check out this resource which covers how you can convert your older iMovie files: About incompatible media in iMovie for macOS - Apple Support

"Convert incompatible media not contained in an iMovie library

To convert an incompatible media file, open it with QuickTime Player (version 10.0 and later) in macOS Mojave or earlier, then save a copy with a new name. This method isn't supported in macOS Catalina.

You can also use Compressor to transcode one or more media files into a format such as H.264, HEVC, or Apple ProRes. These formats will be supported in versions of macOS after macOS Mojave. H.264 and HEVC preserve image quality with the smallest file size. ProRes preserves the best image quality and provides better performance when editing in iMovie, but creates much larger files that use more storage space than H.264 and HEVC files use."


We hope this helps you.


Cheers!
