Is the AVE really fixed in 12.7.1 HD?

[Ginger]

I know how awful video handling has been in PT HD 11.

Just taking an unscientific poll as to whether or not there is truly improvement in 12.7.1? I've been using 11HD but in a music pre-production environment so I haven't had to deal with much video in 11. The lousy handling is what kept me at PT 10 for so long despite not having much needed tools like offline bounce.

I'm finally making the move but I need to know if it's really working now. I have NO time for hiccups because of the video implementation.

I know the codecs are key to having a smoothly operating system and there's no problem there. I will definitely get DNxHD or ProRes files. I just want to know is it really working now? Was it worth upgrading? 10HD has been solid for me. 11HD has not.
