We’re hammering away at Mastering the Crucifix instructional to get it finished now that all the video has been shot! Please check out the test version and let us know what you think: Access “Mastering the Crucifix” demo here.

The main purpose of this test is to see if people like GIFs or MP4s better for the short looped techniques. Marshal used GIFs for 3-D Jiu-Jitsu, but we wanted to explore other options. Let us know what you think!

Below are the pros and cons of each format, but we want to get your opinions before deciding.

Looped GIF Images


  • Supported by practically every device/browser
  • Automatically loads, plays and loops
  • Multiple GIFs can run at once


  • Lower image quality, fewer colors
  • Fewer frames per second
  • Larger file size, demands more bandwidth (~2MB per GIF)
  • No playback controls

Looped MP4 Videos


  • Higher quality video (more colors and higher resolution)
  • Smoother playback, more FPS
  • Smaller file size (~600KB per MP4)
  • Video playback controls


  • Won’t autoplay if more than one video player is on the page
  • Requires user to click each video to play
  • Playing a new videos stops any other
  • More potential for device/browser incompatibility
