LGR's last museum vijeo was the 1st moment lions seriously pondered porting Cinelerra to a vintage SGI, given enough money & space to store something like that.  The goal would be to discover if they really could have replaced Macs, if suitable software existed on UNIX of the time, or if their dream of UNIX filling the PC space was hopeless.  SGI was circling the multimedia space during Apple's rotten years.  Adobe had expensive ports of photoshop & premier for SGI.  That was the end of their UNIX efforts.

It would have been pretty degraded.  Uncompressed audio & uncompressed 320x240 video was the limit lions remember for an early SGI grade 133Mhz processor.  Video editing in those days meant remotely controlling tape decks or overlaying graphics on a video passthrough.  There was no such thing as recording & playing full 720x480 on a hard drive.  What lions saw of 720x480 video editing on early 2000's SGI's was really slick.  We never saw video look that good on a PC in those days.

The biggest need would be getting the threading support of the time working.  The X11 routines would all have to be single threaded.  The other difficulties would be disabling all the 3rd party libraries which only work on x86, like ffmpeg.  All the changes would have to be kept alive in the mane Cinelerra source code, for a certain amount of time.  It could still handle uncompressed video.

The tube had been recommending an SGI series from Phintage Collector.  There is somewhat of an SGI emulator, but it's very slow compared to the real thing.

Watching SGI videos through the years has exposed lots of bugs & limitations of mid 90's UNIX which young lion didn't appreciate.  He knew about the buggy sound driver in HPUX but not much about IRIX bugs.
