# .webm tutorial

## Step 1: video capture
Something akin to FRAPS.
Shadowplay is probably the best option since it captures the last 5 minutes of gameplay.
Whatever you use, just remember where it saves the files to.

## Step 2: importing it
Don't do online converters, you're a big boy, you should learn to do it yourself.
Download Webm for Lazys: https://github.com/argorar/WebMConverter
When you open it you should be seeing this: https://i.imgur.com/rzeLLsV.png
Import your file from step one into the "Input file" field, and change the output if it isn't to your liking.

## Step 3: editing
### First:
Cutting the video file down to the part you want to use (this doesn't change the source file, only specifies which part is going to be converted into the .webm).
This is done by using the "Trim" option under the "Processing" tab.
Just move it until you get to the start point of what you want to convert, click "Set Start", and then move to the end part of what you want to convert and click the "Set End".
You should see a duration, in my experience, try to keep it at around 20 seconds, 30 at the max. If you want to go longer, you'll probably have to reduce your resolution, which is the next step.
### Second:
You'll want to reduce the resolution, probably no matter what. 4chan does not support 2560x1440p .webms.
This is done by using the "Resize" option under "Processing".
Remember, the higher the resolution, the higher the bitrate is needed to make it look good, so if you're making a 20+ second .webm, 1080p is going to look terrible, so putting it at 1280x720p should be your default.

## Step 4: encoding
This will designate and decide the quality of the .webm.

There are two modes, constant and variable, you'll want to use constant so you can specify a max file size, which it will then use to give the .webm as much bitrate as possible while still keeping it within the limit.
Remember to have "Enable high quality mode" enabled.
/vg/ has a max file size of 4 MB, so unless you're really concerned about other people's data usage, there's no reason to not just always put 4 MB.
Do be aware that it doesn't always conform to file size limit perfectly, and can run over it by enough that 4chan wont accept it, if this happens try using 3.9 as the size limit instead.
/vg/ doesn't support audio, so be sure to have that disabled or you wont be able to upload it.

## Step 5: convert
Click "Convert".
Depending on the size, and your computer, this might take a minut or two.
When it's done converting, congratulations, you now have your own bona fide .webm.

As for the "Advanced" tab, there's no reason to interact with it unless you're trying to squeeze out as much as possible.
The only thing you want to chech under it is that "VP9/Opus" is checked as it is both supported by 4chan and should result in better looking .webms.
