I seem to be having problems importing MP4 footage from a GoPro Hero 9. Current example is 4k footage taken, MP4 footage. Vegas is not allowing me to drag into Project Media, but I can File-Open and select footage. This then opens and I can edit as normal. However, I cannot then save these project files. Error warning as follows:
An error occured while saving the project file Untitled.veg
An error occured writing the file. Make sure you have write access to the file/folder and that there is enough free space.
I don't get it. This is Vegas Pro 18, a video editing program and it will not allow user to drag in MP4 files?
