Thank you so much for letting me know about this! I did change some of the code to make sure clips only play when they are in view but this might inadvertently created some side effects. Will look into this ASAP.
EDIT:
I also implemented a check on data type to prevent unsupported files in your selected folder from being selected for the grid. These unsupported files resulted in gray boxes, but I'm afraid I might now actually be excluding some formats that should be supported with this check.
Supported file formats should be:
- webm
- avi
- m4v
- mov
- mp4
- mpg
- mpeg
- wmv
- png
- jpg
- jpeg
Do you happen to notice if the files that start playing but then get grayed out are a format that is not part of this list?
