    I have footage shot at 15 fps and 8 fps. Do we have a simple tool that would speed up time by just playing the frames 30 or even higher in a second without mangling (blur, blend) the frames at all?
    I have tried Twixtor, but I am not sure if it leaves the frames untouched and its rendering time is HUUUGE!

    Time remap will speed up your footage easily and precisely without attempting to create new frames which is what Twixtor does.

    Your inquiry implies you are misunderstanding several of the basics of time compression. Try telling us what you’re trying to achieve and why you shot whatever it was you shot at those frame weird rates. And how did you shoot at those rates? What camera shoots at 8 fps? What shutter speeds?

    This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

    there are a couple of ways you could do this, but which way would be the best depends on exactly what you are looking to do.

    if you wanted the speed to change during the play back, like speed up, or slow down, then time remapping would be the best way to go.

    if all you wanted to do was speed up the 15fps (or 8fps) footage to 30fps, then you could use the interpret footage settings (select footage in project window, then choose file>interpret footage>main) and set the frame rate to 30fps (or whatever you want). now when you take in into a comp it will play back at the frame rate you set ae to interpret the footage at.

    if you wanted a little flexibilty, so it was easier adjust the speed, you could just bring the footage into a comp (say a 30fps comp), then choose layer>time>time stretch… enter the percent to speed (or slow) the footage up by.. so if you wanted to go from 15fps to 30fps, enter 200%.

    note that you can enter an equation for more difficult speed increases, so for 8fps to 30fps, you could enter 100*8/30 to have ae calculate the speed increase.
