However, I thought I'd try the 1080p files to improve the quality but when PowerDirector plays them, both in preview and in the timeline, the audio comes out as a hissing sound.
I can preview these files directly from the folder on the Chromebook and on the camcorder so there's no issue with the files. It would appear to be an unsupported codec causing this in PowerDirector but I'm not sure how to remedy this.
Is there any solution or will I have to switch to editing on desktop?
