Converting video for the sakugabooru

Using Avidemux to create MP4s.

1. Drag file of choice to avidemux, let it load.
2. Use the slider to get the start of the cut you want and press the A button, use B to mark the end. Left and right arrows should allow you to frame step.
3. Go to Audio > Select Track and uncheck the audio streams.
4.1 Go to Video -> Filters -> Transform -> swsResize
4.2 Enter height of 480 (make sure to select the right Aspect Ratio)* and press ok and close.
5. In the left side of the main screen, select video output to Mpeg4 AVC (x264) and set output to mp4 Muxer
6. Finally go to File -> Save as to export your desired clip.


If you want to convert to webm, I use a firefox plugin called firefogg.
What I tend to do is in avidemux I leave out the filter resize and resize it when I create the webm.

Using firefogg:

1. Click on "Make Web Video" in one of the Firefox menus, usually under Tools.
2. Select the MP4 you just created.
3. Select Advanced Options
4. Here uncheck Audio, set height to 480 and quality to either 7 or 8. You don't really need to set anything else.
Sometimes 7 can look a bit low quality so use 8. Just depends. Use 8 to be on the safe side. 6 and below nets in really low quality stuff and 9 and 10 result in some bloated filesizes.
5. Press Encode and you are done.

* Regarding aspect ratios. General things to note:
If the video looks SQUARE then it is likely 4:3
If it looks like RECTANGLE or WIDESCREEN then it is likely 16:9 (Though some movies tend to use different aspect ratios so be wary)
When converting from a DVD source your video may end up slightly squished, this is to do with how the video is stored (google anamorphic video) in cases like this you'll have to hard encode your resolutions.
