https://youtu.be/jXR1rYeOPFw Way to kill half a hour. I tried extremely downgraded virtual machine, using only qemu's TCG and not full-speed virtualization. As you can see, even at those speeds as long as file remained in ramdisk it was possible to get some slideshow out of real world clips from my old Nokia or one I downloaded from Internet waaay back. https://disk.yandex.ru/d/7Y1MPn9TTPzFiA 1.6 gb iso image I also booted it on my current machine, and even single-threaded h264 decoding in old Cinelerra-CV was able to keep up with 1600x900 60 fps screen recording from my laptop :) I manually updated kernel due to all those recent vulnerabilities found in it, and decided to entertain myself offline a bit while I was loading my machine to see if new kernel was good enough. Inside old ISO kernel 2.6.37, compiled with KVM but without some isa network card drivers, so it worked in qemu with e1000 default network card, but not in PCem with ISA based ne2k. 86Box should have PCI variant of it. I think older, quicktime-for-linux-based Cinelerra really mostly was geared towards uncompressed video - it plays so much nicer if you can waste 25 mb/s per 640x480 clip in otherwise very restricted environment :) Feel free to skip this email, it just me fooling around with toys
