The program that I will be using for this tutorial is Xmedia Recode, which is an easy to use and free recoder with a gui.
Download here: http://www.xmedia-recode.de/download.html
 
Once you have the program installed, click open file and choose the full video that you want to make a webm (we will cut it down later if you only want a few seconds of the video in the webm). Now you have a big set of tabs below the table that is showing the videos that you are going to recode. Under the format tab, which should be open by default, make the profile "HTML5", and then set the one directly below it to be "HTML5 [desired resolution here] (webm)". The resolution that I always choose is usually 640x360, because that's a nice small resolution so it's easy to keep under 3mb, but not so small that anything on it becomes hard to watch. Now, below the whole Output format part there is another part that says "Output stream type". Make that video only, as 4chan doesn't take audio webms.
 
Now to move to the fun stuff. Go to the video tab. Most of these you will want to keep to the defaults unless the video is longer than normal and is being a pain in the ass to get just under 3mb, such as if the video keeps popping out as 3.001mb, in which case you will likely just be changing the Bitrate and the Maximum Bitrate. The bitrate will be the target bitrate that your video will want to be at, and may go a bit higher or lower depending on what it is encoding. The Maximum bitrate will cap the bitrate to ensure it never goes over, with the possibility that some parts of high movement will lose a ton of quality. If you are going a full megabyte over the limit, head back to format and lower the resolution.
 
Now if your video is longer than you want the webm to be, you will want to head over to Filters/Preview. Here you can drag along the video and somewhat preview what it's going to look like after being recoded. If you know what you're doing and want to change some options on the left side, go ahead. Below the video there is a timeline that you can drag along, and then below that there are multiple other buttons. We will be focusing on the ones to the right of the timeline controllers. The brackets will let you tell the encoder where to start and finish encoding. The open bracket (the one that faces openly to the right) will set the start time, whereas the one directly to the right of that will set the closing time. The other brackets with arrows pointing into them will reset the start and finish times to be at the beginning and endings of the full video. Once you set the beginning and ending frames, you might want to consider rounding them to the nearest second by going to where it says Start Time and changing the variables in boxes and changing the last number to be 000. (Such as 2:40:232 becoming 2:40:000) This will help you avoid split second frames of an earlier camera cut.
 
Once you have that all done, simply head back to the top, click Add Job, and then click encode. By default the program will export the video to your user's video folder, you can change that by going to the bottom and changing the output settings.
