  • Flow transition has stopped working?

    Posted by Rikki Blow on August 15, 2019 at 2:38 pm

    FCPX 10.4.5
    OSX 10.13.6
    MacBook Pro Late 2016 TouchBar i7 15″ with Radeon Pro 460

    I’ve noticed my Flow transitions have been a bit jerky recently, and on a current interview edit, I’ve now realised that I can no longer select ‘optical flow’ video quality on flow transitions – I’m sure I used to be able to do this, but now the tick is on ‘Normal’ and all three options are greyed out.

    Any thoughts?

    Hi Rikki:
    “Flow” is a transition…you don’t add “Optical Flow” processing to transitions. That’s why it’s grayed out.

    Am I just having a senior moment?

    I’ve been editing with FCPX since it came out, and I am certain the video quality options have always been there for flow transitions, and I would sometimes select frame blending or choose optical flow depending on which looked best.

    Even if I’ve somehow misremembered this (and I use FCPX nearly every day so seems unlikely), I’m sure that something has definitely changed recently, because transtions that looked OK on a rendered film, are now looking clunkier on a second version.

    Something about flow has stopped functioning, and I’m desperate to find a fix because what used to work brilliantly in interviews is now looking clunky and amateur.

    Hey Rikki,

    The Flow transition doesn’t have any visual / quality options, just the audio curves.

    I’ve noticed, at least when I’ve used it, that I need to park the playhead over the Flow transition until it’s done analyzing (indicated by a little note in the the lower left corner of the viewer and the progress indicator at upper left). When I fail to do so, those transitions are indeed poor.

    Try deleting one of your Flow instances, re-apply a new one, and park the playhead there for a few seconds.
