What I know about blender's V.S.E. is that it can cache a certain amount of frames before dropping frames(Related). But, on my Ipod I have video editors like Imovie, and Cute Cut and there is never a delay with the videos, even with different FPS. (maybe because Cute Cut and Imovie have a MCFI?) So what method do they use, or does Blender just use an out-dated version of Caching? Also my Ipod has much smaller RAM so it wouldn't be able to Cache much. Then when I'm finally done making a video why do have to I render it? With other Video editors, like lightworks or Filmora or Imovie or CuteCut or WindowsMovie maker or pretty much everything else, I export it. So is Blender's VSE outdated- or the opposite, it's so good that normal pc's can't handle it? Which begs the question, why not have a dumbed down version for normal pcs?
Wow, ok that's a lot a questions, sorry, but to narrow it down to one(two) question(s):
How does Blenders VSE work, what makes it so slow?
