Hi there,
As the resolution (W) is in odd, that is why you are getting this error.
Please make a back up of this project (save the same project with different name on another location) and then click on modify > rescale projcet and change the resolution to 1100 * 752 or 1102 *752
then publish the .mp4 and check 'force republish all slides'
Please try that and reply.
Thanks.
