- Complete redesign of configuration file format. The configuration file is now much more flexible and easy to look at.
- Various modifications done to the rest of the program to adapt to the changes made in the configuration file. This eliminated some problems existed in the previous version.
- Added progress bar according to @ArmandBernard 's suggestion.
- Cache folders are now created under `'{}\\video2x'.format(tempfile.gettempdir())` by default, and the default key for cache folder location in configuration file has been changed to `video2x_cache_folder`. This makes it easier to manage cache folders.
- Cache folders are now more likely to be deleted successfully even if the program crashes. This is made possible with more try-catch blocks.
- Updated FFMPEG stream migration grammar according to @cr08 's suggestions. All streams (including attachment streams) will now be copied over to the new video.
Video2X is an automation software based on waifu2x image enlarging engine. It extracts frames from a video, enlarge it by a number of times without losing any details or quality, keeping lines smooth and edges sharp.

If you can't find a video clip to begin with, or if you want to see a before-after comparison, we have prepared some sample clips for you. The quick start guide down below will also be based on the name of the sample clips.

If you're unfamiliar of directories in command lines, then here's a short section that might help you to get started.
For example, if you downloaded the sample input video to `C:\Users\[YourUsername]\Downloads`, then the full path of your input video will be `C:\Users\[YourUsername]\Downloads\sample_input.mp4`, vice versa. The output path is also relative. If you want to export the output video to the current directory, just specify the output video name such as `output.mp4`. However, if you want to put the output video in a different directory, you should use relative or absolute path, such as `C:\Users\[YourUsername]\Desktop\output.mp4`.
If you're tired typing everything in, you can also drag the video file directly into the command line window, and Windows will fill in the full path of the video for you.
Enlarge the video by 2 times using OpenCL. Note that `waifu2x-converter-cpp` doesn't support width and height. You'll also have to explicitly specify that the driver to be used is `waifu2x_converter`.
Corresponding sample configuration is shown below. Note that the `waifu2x_path` is different from the configuration for `waifu2x-caffe`. Instead of the binary path, folder containing extracted `waifu2x-converter-cpp.exe` should be specified.
Enlarge the video to 1920x1080 using the CPU. You may also use the `-r/--ratio` option. This is potentially much slower than using a GPU. The configuration file for this method is similar to the previous methods.
Video2X converts the configuration file keys and values directly into options or arguments. For example, in the following sample config, `--scale_width 1920` will be passed to waifu2x.
```json
"waifu2x_caffe": {
...
"scale_width": null,
...
}
```
- Keys having a value of `null` (or `false`, not recommended as it can mean different things in the future) means to ignore this key, thus ignoring both the key and the value.
- Keys having a value of `true` means that this is an option. Only the key will be passed to waifu2x, not the value (e.g. `--quiet`).
