I have a feature film in Vegas 13 edited from a Prores original HD file. It is ProResHQ.mov 23.976 fps progressive, 1920x1080x32, ProRes Audio: 48,000 Hz, Stereo, AAC. It works normally in Sony Vegas 13 last build. i opened it in Vegas 14 and each shot from the feature length scan of a film negative has one or two extra frames added at the beginning of each cut - which were not there in Vegas 13. It completely screws up the cut and will go out of sync with the sound. Vegas 14 is not keeping in sync with the original cut. It is definitely introduced by Vegas 14 because I checked the original file in Sony Vegas 13 and it is normal with perfect cuts. So this is some glitch or bug due to VEgas 14 using a Prores file. I have no problem so far using XAVC files in 14 - only Prores. This is on a Win 7 64 bit Pro with 32 GB ram and Nvidia quadro 4000 graphics.
