Backing up some more cringy floppy disks from 30 years ago the lion kingdom is never going to read, there is the source code for the very 1st audio editor.  That was the 1st productive thing a lion ever wrote.  That was a time when any random piece of software was guaranteed to get tons of downloads.  It's not like that anymore.  You can make a spectacular game or tool now & no-one will ever care.

Lions were even worse jerks 30 years ago than they are now but in hindsight, the lion kingdom was going to die alone & never have any romantic relationships.  It was rightfully a stressful time & there was a lot of cringe coming out ahead of what eventually happened.  At the same time, 60% of men die without having any romantic relationships & lions knew they were rebelling against christian customs.  Can't a lion have some fun?

Tori Amos after plastic surgery.  They say she's almost totally synthetic now.  

Sheriff in space is hitting them out of the park.  She knows what she's got & isn't afraid of a few freudian editing mistakes.

Anyways, making the bottom track always replace, getting rid of the checkerboard for all modes except still frames made single track overlay with alpha work.  

The mane trick is when playing back, it blends directly onto the screen with no alpha channel.  All other modes & nested EDL's blend onto a temporary with alpha channel.  It's not obvious why the lion made this optimization back in 2006 but it doesn't give the same result as blending onto a temporary with alpha channel.  The lion of 2006 probably didn't know there was no alpha channel in the screen buffer.  There's a long way to go, but the good news is the lion kingdom has a grasp of why the different pathways break.

The original video editor 25 years ago had a single colorspace, RGBA 8 bit, & pure software processing.  Reality quickly intervened, forcing that to become a multitude of RGB & YUV colorspaces.  Then, the HD era pushed previewing into hardware.  Finally the 4k era pushed rendering into hardware. 

Technically, if it only supported hardware it could realize the dream of pure RGBA float.  The integer colorspaces are nothing more than optimizations.  There's an extreme investment in optimizing every last clockcycle in software mode even though software mode has become completely impractical.  In some ways, it makes sense to have software mode only support extremely slow RGBA float & focus all practical use on hardware RGBA float.  The software mode is only for bottom end systems nowadays.

Software mode is only used by a few effects like motion, histogram, scopes, blurs, which require passing data to the GUI, recursively reading output pixels, & scanning large areas.  The original idea was CPUs would eventually have the number of cores of a GPU & frames would be split up in the CPU the way they're split in the GPU.  We may still be on that path.  The top model CPUs have 64 cores but memory is still too slow.  That would make RGBA float in software the only necessary mode & 15 years of opengl would go down the drain.

Have any lion coworkers from 22 years ago still not retired?  Anyways, he apparently got his twitter account back, revealing he had a rough go in go daddy management.  The lion kingdom resolved that management was a bad path, long ago.  The best path is staying invisible on the roof.  It would be something if we could all go back to just pet software projects like 1999 again, before the madness.  Learning new skills is madness.

Speaking of retirement, the stonk market has had a monster rally from the 29's back to the 32's.  Lions still don't think the forces at work in the 2020 rally are still at work, manely the quantitative easing which propelled the 15 year bull market is gone.
