I have had great success with content aware "healing tool in LR. One thing I have noticed you will not see the changes in LRT previews. You must export via LR to see changes.
On that note does anyone know how to forego previews and still the enable visual deflicker function. Just trying to save some time.

Maybe you don't have the latest Adobe Dng Converter installed then. Please upgrade. Then previews should look as in Lightroom.

Thanks for that, saved me a lot of time testing.

Im trying to transition away from Adobe and into Resolve but so far i haven't found anything remotely as good as AEs content aware tool sadly. Dead pixel/Object removal etc all seem to leave fairly obvious video artefacts.
