X-form and pitch shifting
 
I've used, and been disappointed by iZotope, when doing PAL to NTSC deliverables.

Since "X-Form is based on the iZotope Radius time-stretching and pitch-shifting algorithms", is there any diference in performance?

Have you tried Time Factory?

i've just finished a feature set of deliverables and found Elastique Pitch by zplane to be outstanding. X-form use to be my go to but maybe not now. Time shift or X-form on monophonic usually works for Dialogue. Always pitch the stems.

I have wondered as well what alternatives besides the x-form are. Have spend a lot of time pitch shifting clip by clip and track by track. Sometimes pitching by stems doesn't work well and artefacts are audible. Besides, x-form isn't great in terms of workflow efficiency. There is a place for the improvement.

I'm looking into Time Factory and X-Form for a client who has historical preference. I've not used either, though heard universally good things about Time Factory.
Just wondering if X-Form is even worth looking at if it uses iZotope algorithms.

Zplane is new to me. Is it capable of fps changes on stems without introducing artifacts? (This is the problem I've had with iZotope. Subtle, but audible watery-birds on dialog.)

+1 for Timefactory.
Great results with the minimum fuss.
I do my stems standalone on a laptop and get on with other stuff on my main rig.
You can demo it.

I use both X-from and Serato. X-from is much slower but sounds better.
Serato is very fast but also sounds good.

What are you using X-Form for?

Don't use a Time/Pitch plugin for FPS changes. Rather, use SRC, it is more accurate and sounds better.
