Now is the time when you need to choose the quality of the video and audio.If you don’t know what to do here, something quick and easy is to just use CRF, which means you let the codec decide on the bitrates itself.
If you don’t know how many cores your CPU has just Google your CPU and you should be able to find the specs somewhere, or 4 should be fine anyway.
Important note #3: If you have a video card, you can improve quality by adding “GPU=true” to the script.
High framerate (HFR at 48fps) was used in The Hobbit and will be used in upcoming films like the Avatar sequels, so why not watch all your movies at higher framerates?
A lot of people don’t realize this, but 99% of TVs made before this feature was introduced are actually capable of displaying 50FPS and 60FPS, and of course most LCD monitors display 60FPS as well.
The files needed for this step are found in this zip folder (~3MB). It is an early version of Avi Synth 2.6 that is more stable and faster for multithreading than 2.5 releases.
