I have 1920x1080 video filmed with the 5D Mark IV at 59.94 and Vegas 16 (latest update) has such a hard time playing those clips on the timeline and brings my project to a crawl. It can barely play the 59.94 clips on draft-auto.
I'm wondering if this is a known issue or bug or if there is a work-around? Vegas 14 can deal with the exact same footage flawlessly at best-full.
