Ich glaube das ist die Lösung...
"I found my notes! These encoding settings should work fine for 68k Macs on System 7-8:
Media space, system requirements and encode settings:
1) Settings: Cinepak, 15 fps, 320 x 240 68k-based Quicktime video @ about 2175 kbps
2) System: LC/Quadra, 68040/68LC040 chipset would be needed
3) Media space example: 400 mb 320 x 240 Cinepak video equals a little under 25 minutes
Encoding for 68k Cinepak video:
1) Enable legacy codecs in QuickTime Pro
2) On Leopard you go to the Advance tab in QT's prefs pane
3) On SL install QT7 player & use terminal command: qtdefaults write LegacyCodecsEnabled yes
4) Open your video files in QT7 player and export them with the proper legacy settings
Cinepak video results:
1) 15 fps loses frame content and 24 fps pushes 68k Macs to their limits
2) 24fps, 320x240, 1800kbps Cinepak settings may offer the best 68k video encodes
3) YMMV - under Basilisk II emulation, I successfully tested a Cinepak sample using QT player
Sample tested: I found a Cinepak .mov video of Apple's '1984' ad here:

Since my Mac Mini and my older Macs are not in use, I watched the sample video above using my chromebook's 68k emulator and doubled the video's size on QuickTime. It was like watching old SD videos on Youtube on a low-end tablet or smartphone; just smooth enough for young kids to watch. Hard drive space is the biggest constraint, although I believe Orb removable drives might be compatible with real 68k Macs. Emulation will work best I think due to the processing power and space of our current systems.
Here's a Quadra 700 playing a full-screen Cinepak video
A friend at VideoHelp.com encoded a 15 fps video using VirtulDub. It played back fairly well on my emulator. He did ask if these videos could be tried on some real 68k Macs, but mine are all dead, even my PPC Macs are down.
Here's the link to those Cinepak encodes if anyone wants to try them out to see how they run on your Macs:

Here's a link to the screenshot of me playing back the video on my chromebook using Basilisk II:
