+## Configuration
+
+All Settings have reasonable defaults, so users do not need to do any configuration before using the program.
+
+Here is an explanation of some of the more important settings.
+
+### General
+
+* Maximum Video Size: Frames are exported at this resolution if the video is larger. Lower resolutions speed up interpolation a lot.
+
+### Interpolation
+
+* Copy Audio: Audio will be saved to a separate file when extracting the frames and will afterwards be merged into the output.
+  * Not guaranteed to work with all audio codecs. Supported are: M4A/AAC, Vorbis, Opus, MP2, PCM/Raw.
+* Remove Duplicate Frames: This is meant for 2D animation. Removing duplicates makes a smooth interpolation possible.
+  * You can disable this completely if you only use content without duplicates (e.g. camera footage, CG renders).
+* Animation Loop: This will make looped animations interpolate to a perfect loop by copying the first frame to the end of the frames.
+* Don't Interpolate Scene Changes: This avoids interpolating scene changes (cuts) as this would produce weird a morphing effect.
+* Save Output Frames As JPEG: Save interpolated frames as JPEG before encoding. Not recommended unless you have little disk space.
+
+### AI Specific Settings
+
+* RIFE - Use Fast Parallel Mode - Speeds up RIFE interpolation a lot if you have lots of VRAM. Not recommended with <8GB GPUs.
+* GPU IDs: `0` is the default for setups with one dedicated GPU. Four dedicated GPUs would mean `0,1,2,3` for example.
+* NCNN Processing Threads: Increasing this number to 2, 3 or 4 can improve GPU utilization, but also slow things down.
+
+### Video Export
+
+* Encoding Options: Set options for video/GIF encoding. Refer to the **FFmpeg** and Gifski documentations.
+* Minimum Video Length: Make sure the output is as long as this value by looping it.
+* Maximum Output Frame Rate: Limit frame rate, for example, if you want a 60 FPS output from a 24 FPS video.
+
+### Debugging / Experimental
+
+* Show Hidden CMD Windows: This will show the windows for AI processes. Can be useful for debugging.
+* FFprobe: Count Frames Manually: This uses a slower way of getting the input video's total frame count, but works reliably.
