Activity Forums Boris FX problem with bcc motion key

    There could be several reasons for this, such as:

    • mask not big enough to cover the moving object in every frame
    • replacement range not long enough / too long
    • feathering too big
    • luma comp set too low / too high

    I think your options are either:

    • adjust the aforementioned settings until you achieve the desired result

    or:

    • render the result that you have an re-run the motion key on the rendered result to eliminate the vertical image artifacts.

    I hope this helps.

    Peter.
