  • recreate every second frame using Twixtor

    Hi,

    There’s a trick for improving compressed video (DV,HDV, DVCPRO etc.) to get a better key using Motion Estimation (there’s even a product from The Foundry).

    My question is.
    I want to keep the speed at 100%, but recreate every second frame using Twixtor, based on the previous & next frame.

    How can I set it up ?

    Thanks
    Eran

    You mean, like stretching it then shrinking it,
    all in one pass?
    Or, prep/precompose a sequence that contains
    half as many frames (i.e. throwing out every other frame)
    then use that (i.e. half the fps of the original) to
    create a new sequence that contains twice as
    many frames (i.e. same fps as the original)?

    Just curious though:
    how would throwing out every other frame
    improve compressed video?
    Having said that, I do this kind of thing
    for cartoon restorations (from film) but
    not for live footage. So I’m just curious…

    Shin,

    I can’t really tell you why it’s working, but I saw a demonstration of it with good results.

    Thanks for tip. Quite basic when you think of it 🙂
