VapourSynth script to automatically handle fields of an MPEG video file to return a Progressive CFR video stream.

"A video processing framework with simplicity in mind"—VapourSynth Project

To add more to that, it's a Script-based NLE (Non-linear editing system).

It's not GUI software rather a scripting framework for videos that uses the Python programming language.

VapourSynth Script files use the .vpy extension (revision on .py being the Python script extension).

For your typical YouTube video it's unconventional yes, but that isn't the goal of a project like this. A Script-based NLE is scripted to handle a specific use case, and be able to be utilised by other programs like GUI editors, video players, hardware players, and such.

You won't need you're YouTube video's edits to be reproducable automatically on other people's PC's, but an edit like filtering colors, stabilization algorithms, machine learning edits, deinterlacing, e.t.c would be. You can generally think of VapourSynth as a framework for plugin creation, though it's extremely versatile and portable and not locked to one program but can be used by any program (as long as it supports it).

This project (VSMPEG) is a great example of a use-case of VapourSynth as it deals with the shenanigans of MPEG video entirely automated (depending on the optional stuff you enable/want to do). This script isn't realtime right now, even on high-end hardware, however, if it becomes the case of the deinterlacing algorithms to shrink in processing time or hardware to improve, this script could be used in realtime as sort of an intermediate layer or plugin to automatically handle DVD playback automatically without any configuration by the user. That would be awesome.

vs-edit is essentially an IDE for VapourSynth Script files. It integrates convenient features like a full fledged previewing system, a Syntax-highlighter, auto-completion, benchmarking, and more.

This saves you ton's of headaches of using VapourSynth from the command line, especially the previewing system!

Note:

• I will presume you know what a terminal (or command prompt) is, and how to open one.
• When I state, "Run ..." that indicates to run a command in a terminal.
• Run python --version, if that doesn't return v3.x.x, then python is a Python v2 (deprecated) binary. Run python3 and if that works, then use that in-place of python in all following commands.

1. VapourSynth, seriously try and use the latest version for this one at all times.
2. vs-edit, What is it? Click here. Linux users: Find this in your distro's user-repo.
3. Python, it's needed for VapourSynth, read VapourSynth's installation guide for information on required versions.
4. MKVToolNix, ensure it's a recent version if not the latest.
5. dgmpgdec158.zip for DGIndex v1.5.8. Download and extract it to a folder named dgmpgdec158.
6. Linux ONLY: wine to be able to use DGIndex v1.5.8.

Important: Do not attempt to use an alternative MPEG indexer like D2VWitch or ffmpeg's indexer. They don't have nearly as much accuracy or efficiency as DGIndex as well as a few bugs I have noticed. DGIndex while old, is incredibly well made by Donald Graft and I want to thank him for his work on it.

1. Simply run python -m pip install --user /path/to/requirements.txt
2. However, please try and re-run the above command every now and then in case there's crucial updates to dependencies that have been made.

1. Run where vsrepo.py and copy the full path it gives you.
2. python <path/to/vsrepo.py> install havsfunc mvsfunc d2v ffms2 lsmas.

1. It needs havsfunc, mvsfunc, d2v_source, lsmas (L-SMASH-Works), and ffms2.
2. All are available on GitHub, you're on Linux you know the deal.
3. Go compile and install it, or use you're distro's AUR/User-Repository and hope it's on it.

1. Move the dgmpgdec158 folder (which should contain DGIndex.exe to C:/Program Files (x86)/dgmpgdec158 (or something similar, but I recommend in C:/Program Files (x86).
2. Add that location to the SYSTEM's PATH environment variable. (how to add to path environment variable)
3. Close all terminal's you opened and open a new one before continuing to refresh the environment variable.

1. Move the dgmpgdec158 folder somewhere, it's linux, so it's up to you. I place all my portable Windows applications in ~/winbin.
2. Add the location of dgmpgdec158 to system-wide PATH environment variable, it MUST be REAL system-wide and not your shell's environment!
   sudo nano /etc/profile.d/env.sh, e.g.: export PATH="$PATH:$HOME/winbin/dgmpgdec158" where ~/winbin/dgmpgdec158 is where DGIndex.exe resides.
3. You might need to logout and log back in, or worst case scenario reboot. If you want to be safe, reboot now.

1. Download the vsmpeg.vpy script file and store it somewhere nice, e.g. Documents/VapourSynth/vsmpeg.vpy.
2. Open vs-edit and drag & drop the vsmpeg.vpy file you downloaded into vs-edit.
3. Feel free to read the instructions near the top of the script and continue away :)
