I am sure I haven’t been the only one to experience this, however - it’s pretty confusing.
I got approved to become an author - which means I sent links to Videohive to review my portfolio. My first attempt at uploading files to sell, I used 5 of the SAME clips that got me approved and they were all hard rejected.
I offered all clips in ProRes codec, and they’re all 4k resolution. I am not sure why the same clips were good enough to select me to become an author but not actually sell them lol.
