I have 4k footage all shot the same frame rate from a Sony AX53 and everything has been fine except now every time I attempt to stabilize the footage using the standard Vegas Stabilize fx the software crashes.
I have tried turning off GPU rendering but still the same behavior.
Does the upgraded stabilize work better in Vegas Pro?
I ran into the same problem with some 4k clips from my Panasonic FZ300, stabilizing with Vegas stabilizer in VegasPro 14. I had this problem also already in VegasPro 13 with the use of the Mercalli 2 plugin and also with the Vegas stabilizer. I don't have the problem with VegasPro 14 when I use the Mercalli 4 plugin. Since the Vegas stabilizer is based on Mercalli 2, I think that this is a bug in Mercalli 2. The strange thing is that not all 4k clips lead to a crash.
A workaround I found: (Batch) render those 4k clips, which causes crashes, with this XAVC rendertemplate.
and use those rendered files for stabilizing, they don't cause the crash.
