Vertical orientation (9:16 ratio)

Is it possible to create a vertical scribe (9:16 ratio) without post-production in a different program?


Thanks!

No. I think 16:9 is currently the only option.


If you rotate all of your elements 90 degrees in the same direction you can build your scribe on its side.

After that you can either use a video editor to rotate (re-encode) the finished video 90 in the opposite direction to create a vertical video.
OR

there are a few ways to edit the metadata in the MP4 code to rotate the video without re-encoding it.


An example quote from a related article on another website:

"True lossless rotation of MP4:

  • open mp4 with hex editor and search for vide to find the metadata of the video track
  • some rows above (for my files mostly 9, sometimes 12) you should see trak...\tkhd
  • in between there should be an @ sign (HEX 40)
  • in the two rows before it the rotation matrix is stored
  • no rotation:

    00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
    00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    40
    
  • 180°:

    FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
    FF FF 00 00 00 00 00 00 00 00 00 00 00 00 00 00
    40
    
  • 90° cw:

    00 00 00 00 00 01 00 00 00 00 00 00 FF FF 00 00 
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
    40 
    
  • 90° ccw:

    00 00 00 00 FF FF 00 00 00 00 00 00 00 01 00 00 
    00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 
    40
    

Alter the file as you need it, and it should be rotated in players that support the rotation flag (most current players do)."


A google search will allow you to find more specific instructions.
