I just upgraded from the 2020 older version of Movie Studio to the 2023 version, but it cannot read MP4 files... any audio is stilted and the video is blank (screen black). The files can be loaded on the time line, but there is no video. JPG's and WMV files work as advertised. The MP4 codec reader should be included with the ultimate upgrade. I am using Windows 10 Pro, Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz 3.50 GHz, 8 gig RAM with 64 bit processor. Please advise.
My Ultimate Version 2023 will not read MP4 files...
