the video installations I made in 2006-2008 did the following on a single Mac Quad G5 (later MacPro)
- Display live feed from 1080i camera
- record live cam to disk at full frame rate
- put live feed into 300 frame buffer and scrub through it at various rates
- play up to 4 1080i clips off of two hard drives.
This was all done with plenty of CPU in reserve. The codec was AppleIntemediate which is simply Photo-JPEG with specific CPU optimizations.
You can see one of these in the lobby of OneArts Plaza in Dallas, Qualcomm HQ in San Diego and several private collections.

When talking about video codecs, I think/thought there is actually no difference, that is, motion-jpeg would be just a name for "photo-jpeg

they still have three different FOURCCs :
"jpeg" for Photo-JPEG "mjpa" for Motion-JPEG-A "mjpb" for Motion-JPEG-B
but different lists of FOURCCs list them differently... it seems that
there
are dozens of other variants of those, specific to various companies. I
only
tried using the three above, IIRC.
