VideoScript is a collection of video processes including video Upscale and video frame Interpolation, it uses Python to generate FFmpeg, Real-ESRGAN and IFRNet command line script and performes serial processing on scanned mp4/mkv videos.

VideoScriptWebUI is a local web user interface developed with Dash, it has the goal of enhancing user experience.

⚠ Currently only compatible with Windows users who have Nvidia cards.

Simplest. Python, Tools are already setup.
Advantage : Beginner-friendly

1. Download and extract the Embedded release

• Run the RUN.bat to launch WebUI

Need to install Python dependencies, add tools to PATH manually.
Advantage : Freedom

1. Download and extract the SelfSetup release

2. Download and install Python 3.10 if you dont have.

3. Install dependencies

   pip install -r requirements.txt

4. Add tools to PATH

   Below tools are included in self setup release :

   FFmpeg full build for hardware acceleration.

   Real-ESRGAN-ncnn-vulkan for video upscaling.

   Ifrnet-ncnn-vulkan for video frame interpolation.

   Important

   Make sure to add

   • <pathTo>\ffmpeg-full_build\bin
   • <pathTo>\Real-ESRGAN
   • <pathTo>\Ifrnet

   in the environment variable PATH

• VideoScript.py

  Run the script on where videos are located and follow the command line indication

• VideoScriptWebUI.py

  Run the script, a web page should be opened automatically, select a process, select a path where videos are located, SCAN then RUN. The processed videos are under a folder of selected path example ./upscaled.

• optimize

  Reduce the video biteRate in order to gain storage space.
  The processed videos will have a bitRate = width * height * quality, which quality=3 is generally the lowest value before appearance of artifacts (bad images, blurry...). In other words, humain wont notice the visual difference between video of quality 3 and 6.

• resize

  Reduce the video width and height.

• upscale

  Recover old video from 360p to 4K, enhance video quality.
  Begin with a transformation of video to image frames, then upscale each frames, finally reassemble to video.
  It has the ability to start from last upscal progress if the "_upscaled_frame" wasn't deleted.

• interpolate

  Increase video frame rate (FPS), smooth video motions.
  Begin with a transformation of video to image frames, then interpolate between frames, finally reassemble to video.

• merge

  Merge all video, including each of its audio and subtitle by option, into mkv. Then use media player as PotPlayer to switch between video/audio/subtitle.
