Hello,
I have an advertiser that wants to run .mp4 video ads. The pre/post roll and overlay options are not really relevant since these are stand alone banners. I just want the banner to show up like any other .jpg or .gif banner and go to url https://x.blah when clicked. When I try to upload this .mp4 banner using the web or url options, I get an error ("The uploaded file does not have a valid extension. The file must be an image file (JPG, PNG, GIF, etc.).
Please make sure you selected a valid file.") And as noted, the inlay or overlay options aren't really relevant. (And also, the image shows up as broken when I tried to use these options.)
How can I use this .mp4 banner for their campaign?
