Activity Forums Audio iZotope RX5 in FCPX cuts off end of audio

    Sorry Robin,

    Not enough coffee and an aggressive spell checker here.

    You said, “Their support has proven to be by far the worst I have experienced in a very long while, especially for such a pricy product! Only half-a$$ed responses that were never actually useful and you got the impression they didn’t even bother to read what I wrote. Absolutely inexcusable. They will never see another penny from me. Which is unfortunate, since in principle the tools are great.”

    I thought this was referring to Apple and FCP.

    iZotope has a long and successful run in audio apps. I use them effectively in Pro Tools and have for maybe 10 years. I have FCP X, but have never used iZotope plugins.

    I googled FCP and iZotope and perhaps this will give you some help. It’s from the iZotope support site.

    [Ty Ford] “I thought this was referring to Apple and FCP.”

    Not entirely sure how it could have been in context, but… ok.

    [Ty Ford] “I use them effectively in Pro Tools”

    Also not sure if that’s supposed to be some sort of consolation, and if so, how? They’re mostly fine in Logic Pro as well. So… now what?

    Doesn’t get me even any closer to an actual solution either way, unfortunately.

    [Ty Ford] “I googled FCP and iZotope and perhaps this will give you some help.”

    Um… thanks?

    Believe it or not, but not only have I also googled my fingers bloody, but I’ve also (as I already stated in my initial post) had several utterly useless exchanges with iZotope’s support. And yeah, I actually know how to apply a filter in FCP. Not something I need to google nor turn to iZotope of all people to learn. Never mind that what they suggest on that page is painfully WRONG and DANGEROUS and will quickly and easily jeopardize one’s entire FCP project! So it’s actually quite fitting that they would post something like that. Only further showing they are clearly FAR outside of their lane on matters of FCP.

    Bottom line: they are selling up to TWELVE HUNDRED DOLLAR packages to FCP users that factually do not work as advertised (assuming you can even get them installed that is!) and for which they are clearly too ignorant or simply disinterested to GET working. Cuz hey, they already have my money, right? (and refuse to refund it!)

    This has been an issue for years not months or days, as you can easily see by the starting date of this thread! If only I had known of Accusonus before I was stupid enough to buy TWO updates from v5 on. ????????‍♂️

    They need to get their act together or just plain stop claiming that their filters work in FCP. Simple. But being told they work great anywhere else contributes nothing to an actual solution, sorry.

    There you go! Got that off your chest? Happy to be a platform for your displeasure.

    I’ve found that the old send and return audio files, while a total PITA, does work. Perhaps not with iZotope plugins. I haven’t tried it with iZotope and FCP X. Perhaps I will.

    Anything else then?

    I completely agree with Robin and couldn’t have put it better myself. I am having the exact same problem which proves the issue lies within the iZotope programming. An expensive piece of software such as RX7 should not be producing these problems and is not acceptable that they have left the issue to go on for this long. I hope the message gets through to them as the community should not be paying for products that do not deliver what they have promised.

    I have noticed this. If you go into the options of the RX you can turn off the latency buffer. BUT, your audio is now delayed and out of sync.

    It’s not even fixable with compound clips.

    I’m editing a short horror film and there are some very clipped screams and shouted dialogue from the boom mic. De-clip does a great job of restoring the audio. My preferred workaround is to locate in finder, control D to duplicate (for a safety backup) and do a destructive de-clip edit on the file. Jump back to the timeline and the distortion is gone with no latency issues. Just make a list of bad clips and do them in one go. The backups can be deleted once you’re happy.

    I’m using RX6.

    What would be nice is an FCPX ‘bounce audio’ function. Like Logic Pro x does.

    Alternatively you could export an XML file to Logic. then round trip it back once processed. I haven’t tried that yet.

    iZotope doesn’t “officially” support FCP and, years back when I contacted them they blamed this on FCP’s audio handling. RX is up to version 10 now and I don’t think this is or will change.

    Other options like Accusounus have come and gone. CrumplePop went from FXFactory distribution to BorisFX and looks like it’s more expensive than it used to be. It’s kind of sad to be boxed into such limited options.
