This was a tool used personally by me and some TOs when Slippi just came out, it was a quick and dirty prototype to get quick highlights. Nowadays, project clippi is the most comprehensive and complete tool for this, so check them out: https://github.com/vinceau/project-clippi

Uses slp-parser-js [https://github.com/project-slippi/slp-parser-js] to generate JSONs needed to feed replay combo data to Dolphin

Install node – https://nodejs.org/en/download/

• Download or clone this repo

• Command line: run "npm install" on the directory

• Then, create a subfolder called "files" and place inside all the .slp files you want to work with.

• Once you have done all that, command line run node app.js on the directory to execute the script, wait for it to finish and it will output a comboData.json file in a auto-generated generatedJSONs folder.

Note: It is configured to only get combos that inflict +60%, end the stock, and is not a wobble

For the following, you need to have the Slippi Dolphin for replays, this typically comes together with the Slippi Desktop App: https://slippi.gg/

• Go to the dolphin-slippi directory used for replays, typically at C:\Users[User]\AppData\Roaming\Slippi Desktop App\dolphin

• [Optional] configure the Graphic settings/Gecko codes in this Dolphin instance to what you prefer. Personally i turn Game Music OFF since it doesn't go well with the nature of this recording effort.

• Copy the generated comboData.json from generatedJSONs folder to this directory

• Then, command line run:

• Dolphin.exe -i comboData.json -e "[full path to melee Vanilla ISO]"

A dolphin screen should open, and after a little bit the gameplay sections described in comboData.json should start playing one after another. When it goes through all combos, it defaults to the "waiting for game..." screen.

While it's playing in Dolphin, you can capture the footage with OBS or any other recording tool.

After playing and recording, you might notice there's a lot of black screen time in between replays, and it's all in the recording, of course it's a pain to edit this out manually if there's a lot of footage.

One kind soul on the Project Slippi Discord provided a Python script to go through the video file and automatically remove those pesky black screens:

Requirements

Install Python 3.x: https://www.python.org/

ffmpeg for Windows: https://ffmpeg.zeranoe.com/builds/

blackFrameRemover.py: https://gist.github.com/Chaparro/7f8b0b9bfaf38dae469e635f51a69a9e (I've modified this to use mp4 source)

Get this script to where your video files are, edit the input and output names to your liking, then run Python blackFrameRemover and wait for it to process the entire video.

Any other edit you want is on you, get comboing!

Ignore Wobbling

Added a validation that looks for 8 or more grab pummels, these combos will be ignored.

Toggle between combo highlights and conversion highlights

Running node app.js -c will get data from the conversion objects instead of combo objects, Slippi's conversions are more lenient than slippi's combos and thus can be used to create highlights when there aren't many true combos in the replay files.

Parameter configuration

You can configure some parameters, in this case, you can configure the following:

• shouldKill = true / false;
• wobblingBanned = true / false;
• comboPercentaje = 60 / any number;
