Videos used to import ok (unless they were recorded without sound, who knows why those didn't import), but as of about 1 month ago none of my videos import, and I get this error, "The movie files contain no video frames."
Here is a link to 2 sample videos I recorded (4k and 1080p, each with different fps to see if that makes a difference for anyone testing this): https://drive.google.com/drive/folders/0By2jdagg930aVUVudHlBT0s5MEE?usp=sharing
Thank you for any insights!
