Hey,
Well, flicker is a question which comes to light at least a couple of times per year for me.
I've been thinking about fixing it (once for all) this spring, but the lack of time made me... go back to FCP7 and use its super basic default deflicker - especially for that and no other action - on this project as a midtime export. Very slow of course but efficient on this project at the end of the day.
However, taking the file back to it just for deflicking is out of question now...
So far, I'm therefore testing solutions.
There's indeed the default studio TimeLapse Deflicker I didn't try yet (is it a classic deflicker btw ?); I have a "flicker remove" as a Sapphire ofx, a couple of tricks by tools not really made specifically for that "but it works", and the well known flicker free from digital anarchy that I'm not owning anymore...
Thanks to Peter and Bruce to add their suggestion here, I'll add it on the list.
So guys, if you happen to find a solution that (1) is preferably free*, (2) works in any situation, (3) is focused on flicker and easy to use and (4) is efficient each time : feel free to post here, I'll do the same
*TL d. is in the studio version (well ok) but not Flicker free or saphirre f. removeBecause as Marc wrote, the fact that the tool is not specifically made for that can make it tricky, whereas a real deflicker won't be bothered by motion for example.
