Have been happily editing my ProRes project with MSP15. then came a sweet offer to upgrade to MSP17. no mention in the promo that it can't handle ProRes files. i also checked a trial of the bait-n-switch fraud of MSP18 (which i don't want), and it does handle the ProRes files. Numerous mentions in the community about this msp17 problem so Magix knows, but support plays dumb and refuses to give me a refund! pretty sleazy.
i even suggested that they keep my money, but give me an older version of Vegas (17 or 18) and keep a client who would most probably upgrade to a newer Vegas. nope, "policy" bs. use Handbrake they say to change ProRes files into something MSP17 can use. more bs.
trying MSP17 cost me a week as edit file couldn't be opened back in MSP15, had to rebuild the edit with backups. Magix sure trying hard to lose clients, both with the bait-n-switch software and deceptively removing capability and calling MSP17 an "upgrade".
though i'd prefer to stay in the Vegas ecosystem, right now i'm having to hand off work to my assistant. his Premiere is of course handling the files perfectly....
