Hi Paul,
Yes, the file does first hit your server. However, .mp4
files aren’t ones that WPEngine forbids, at least to the best of my knowledge. SyncS3 itself doesn’t care what file type you upload. Those considerations are handled at the server and/or Gravity Forms and WordPress levels. That said, MP4 files are definitely supported by WordPress.
Do you have any kind of security plugin that might restrict file uploads? If not, add the following line of code to your wp-config.php
file, and try again:
define( 'ALLOW_UNFILTERED_UPLOADS', true );
