Sony a7III XAVC S 4K 100M 4:2:2 10 bit

Hello,

I have some Sony's XAVC S and want to convert it to Apple Pro Res 422. Some files are in 23, 976 fps and some are in 60 fps. All the files are in 4K. Tried a couple of times to convert it in Media Enconder, but it crash every single time. Fisrt time working with this codec in 422 10 bit. I made a batch list and it crashed in the third clip. Then tried one clip per time and it also crash. Does anybody know why media enconder can't finish this job?

Thanks a lot
