VALIDATOR-8 (Video Resolution Error)
Video width is 720, video height is 576 and pixel aspect ratio is 1:1
The dimensions and/or pixel aspect ratio of the A/V MUX asset do not meet our technical requirements.
Review the height, width, and pixel aspect ratio. A re-encode will most likely be required. If the file is a ProRes file then you can attempt to adjust the pixel aspect ratio (pasp) within JES Extensifier and reupload.
