I'm still on 10.11.6, I might need to update here soon, so I was wondering what the last OSX version that
works with FCP7?

hi Joe,

I'm pretty sure that High Sierra breaks FCP 7. Subsequent versions don't work with 32bit apps,which FCP7 is. (or so I've read)
so last one to work is OSX12 Sierra

but be aware that as move up from where you are now, more and more smaller things may stop working.

Yeah, I concur, El Capitan was the last for me using FCP 7. I keep it installed on the model 4,1 8-core tower
I've had for a decade, to handle old FCP client projects I don't want to transfer over to FCP 8.

FCP 8 (AKA Premiere Pro CC) works fine under High Sierra (10.13) but watch out, 32 bit Quicktime ends when you install Mojave! All 32 bit media will need to be transcoded to work in the 640bit world.

So my question is, what's the best batch processor to use?

Best, as always.

Joe Riggs:
Come OSX Mojave, the jig is up for FCP7. FCP7 worked increasingly poorly in the operating systems after Lion, and couldn't run at all in OSX High Sierra, but you had the option of making your computer dual bootable. That way FCP7 runs happily in an earlier operating system in a bootable volume of its own, and FCP7 in that volume and your newer software in your up-to-date bootable volume, can exchange files. I run FCP7 in Lion and Mountain Lion volumes, while jumping to a Sierra volume to run other software. Occasional reboots become a part of life.

Mojave breaks this happiness by practically demanding that it run in the APFS file system. The pre-High Sierra operating systems run in the HFS+ file system and can't write to APFS.

You might as well use two computers, for the old and the new, and pass data back and forth with an HFS+ formatted portable hard drive.

Loren, your report is baffling. "32-bit" and "64-bit" pertain to operating systems, and programs, not to media files. When you say "32 bit Quicktime", do you mean the old QuickTime (Pro) program 7.6.6 on which FCP7 leaned, or do you mean QuickTime media files, namely .mov files?

Now a .mov video file does specify a codec, and a codec requires a decoder to play the video, and that decoder is a program which can be 32-bit or 64-bit and may or may not be operational under one or another operating system. One can imagine codecs for which there are only decoders (and encoders) that Mojave can't handle, or that only Mojave can handle. I'd be shocked if any video .mov file in any common codec couldn't be used with Mojave. Yet you say old media files need to be transcoded for Mojave. "Transcoded" means transformed to a new codec, and for lossy codecs this would imply increased loss. Unacceptable!

Please clarify what exactly Mojave does to what. I am avoiding the post-Sierra operating systems because their requiring APFS disk format ruins what is to me the main advantage of Macs: its easy multibootability. Perhaps your alarm really revolves around the new file system.
