I have Adobe Elements 18 and a Canon G9X Mark II. I am able to download pictures to Elements, but every time I try to download a movie, I get the error "Elements Organizer cannot obtain files from this device." I have no problem downloading movies to the Mac when I use Photos. The Canon camera movie specs are:
Premiere Elements can certainly work with MP4s. And the Video Importer can download files from a camcorder attached via USB. Though this isn't a traditional camcorder. It's a still camera that shoots video, and that could mean there are some variables. It's possible, for instance, that your video is using a variable frame rate compression. So we may have to dissect the video to find out what it's complete specs are.
What operating system are you using, by the way?
What happens if you use your operating system to manually copy the video from your camera to your computer and then use Add Media to bring the video into a Premiere Elements project?
I am using Mac OS High Sierra. I was able to download the movie with Image Capture. Once I downloaded the movies to the desktop, I was able to import through the Elements program. Do you know why the downloader didn’t work? I was able to import movies with different HD files size options and it still worked with Image Capture.
Do you know when the update that will allow the iPhone HEIC format to be displayed will be released?
