Follow What size of vid can I upload? April 05, 2018 19:46 ManyVids MV Stars General Questions Any vid above 1 minute 30 seconds can be uploaded. The maximum file size for a vid is 5GB. Comments hotlynn March 23, 2018 23:20 I am trying to figure out why it has to be in mp4 video version now. That makes all videos only 5 minutes long. Please tell me what and how to do it to make it loner like I use to do wmv for a 15 minute long video.
