It’s probably to late but for the record and for other facing the same saituation
you can try to:
ºCreate a new project with the right framrate.
ºIn the avid projects folder, copy the bins containing
the wrong framerate sequences to the new project.
–>avid should ask if you want it to make new sequences with the right framrate. say yes.
verify if no black frame appeared, maybe recreate precomputes. tchek it out.
good luck!
