An old problem popped up in Vegas 20 that I think was solved in Vegas 19.
My Canon XF300 makes a series of 2Gigabyte MXF files during a long shoot. I place them all on the timeline butted up against each other. I render pretty exclusively with Vuokoder making MP4 files.
Occasionally (I know that is not scientific) at the point between two events, a couple of highly pixelated frames are generated FROM AN EVENT SEVERAL EVENTS PRIOR. For example, a pixelated fragment of the third event might appear between events 6 and 7.
In an old thread, someone speculated this might be some kind of a buffer overflow.
My old solution for this was to put one empty frame between frames 6 and 7 in the above example. That usually cured the problem. But then it went away, maybe in version 17 or 18.
Now, to get a project out the door, I use FFMPEG to concatenate the MXF files into a single file and load one very large file into Vegas 20.
Anyone else having the problem in Vegas 20?
