From SDA Knowledge Base
After you've successfully recorded your speedrun, you're not quite done. You're going to need to do a bit of processing on your recordings to get a video that you can submit to SDA. There are two ways to get this done.
Anri-chan is an incredible tool made by some of the fine folks at SDA that makes video processing easy.
What Anri-chan will do for you
- Prepare sample and test capture to help identify any recording capture issues
- Process raw recording files from a variety of screen recording programs and capture devices into a format acceptable for an SDA submission
- Process multiple raw recording files into a single submittable video file
- Extract recordings from a DVD player for processing
- Correct some video alignment and bobbing issues
- Add audio commentary tracks to a fully processed video
What Anri-chan won't do for you
Yua is a user friendly tool that is currently in active development. In time it will replace Anri-chan. For additional details, go here.
If you encode a run by yourself then you will be writing your own scripts using AviSynth. AviSynth scripting is an advanced topic. All beginners are recommended to use Anri-chan instead.
