  1. =========================================
  2. ==How to make WebMs for 4chan : A guide== //for /ssbg/
  3. =========================================
  4.  
  5. There are several ways to turn a video file into a webm. Some choose to use Gyfcat, which is
  6. perfectly viable and an easy way to turn a video into a webm/gif. This guide will focus on using
  7. WebMBro/WebMConverter to make 4chan appropriate webms due to its versatility.
  8.  
  9. ==Things you will need:
  10. =========================================
  11. 1. video file you want to convert
  12. 2. WebmBro's WebMConverter (https://github.com/WebMBro/WebMConverter)
  13.  
  14. ===To make a WebM using WebMConverter:
  15. ================================================
  16. This is largely self-explanatory when you open the program, but I hope to give some useful
  17. tips for it things either don't work out or remain inefficient.
  18.  
  19. 1. Load your video by Browsing in the Input file.
  20. 2. Rename your output file to whatever you want.
  21. 3. Delete/keep a title if you want.
  22. 4. Change resolution:
  23.  
  24. -Standard phone recorded videos will have a huge resolution that makes it inefficient to
  25. view in passing on a thread on 4chan.
  26. -I've personally found resolutions between 450-600 to be ideal for thread viewing.
  27. -Remember to leave the other resolution parameter at '-1' to auto-scale the entire video
  28. -4chan will not allow webms with greater than 2048x2048 resolution.
  29.  
  30. 5. Set the time frame of the video that you want to convert into a webm.
  31.  
  32. -Remember that 4chan doesn't accept webms that are over 120 seconds/2minutes in length.
  33.  
  34. 6. Set size limit to 3 mb. (ignore if making a longer webm for a primer)
  35.  
  36. -Sometimes, when making a webm, the video will stop converting prematurely. This is because
  37. the webm had reached the size limit according to the specs you set it to convert it at. To
  38. overcome this, particularly for longer webms, changing the resolution might help, but the
  39. most important step is to change the bitrate.
  40. -I've found that trying to calculate the exact bitrate (size/time) to be an inefficient art
  41. since the program will attempt, but not guarantee, an approximate bitrate.
  42. -A good rule of thumb is to instead see what bitrate the program normally converts your
  43. requested file at, then lowering that value depending on how much time left you need to
  44. convert. Again, this is not an exact art, but using proportions can be helpful to maximize
  45. size and quality for a given amount of time.
  46.  
  47. 7. Don't enable audio.
  48. 8. Convert.
  49. 9. Enjoy your webm.
  50.  
  51. 9a. If you want to make more webms from the same video file, remember to CHANGE THE TITLE of your Output
  52. file, as the program will otherwise simply overwrite your old webm with your new clip.
