[PYTHON] Import serial number videos together with Aviutl

Introduction

The purpose of this article is to automatically import the videos with serial numbers created as a result of jampcutting the videos using the article (https://qiita.com/merarli/items/1b7819adbae7fad3c9b4) into Aviutl. I will. __ Therefore, it is assumed that the following videos with serial numbers exist.

Motivation for creation

I succeeded in automatically jump-cutting with the great leader __ (https://qiita.com/merarli/items/1b7819adbae7fad3c9b4/)__, but the next thing I'm waiting for is Aviutl. It was to drag to the extended timeline of. I automated jump cuts to make money by posting videos with great effort, but this is meaningless ... Well, what should I do! !! I created it with the motive of.

result

I will put the code created earlier.

How to use

Set the path where the video is placed in the variable (m_path). After that, if you run it with a command prompt or anaconda, an edit data file (make_exo.exo) for aviutl will be created directly under m_path. If you drag make_exo.exo to the extended timeline of aviutl, the serial numbered videos will be loaded into the timeline.

exo file description

The explanation of the sample data exo file is described below. Since it is a serial number, create a program that outputs information according to the rules of this file. I can't confirm each parameter because I basically just read it from the exo file.

This code explanation

I may write it at a later date. It is output to a text file in the order of the basic exo file.

Finally

This program was created by an amateur of the program just to make it easier. Therefore, I think that there are many cases where the way to write a program is not reached. In that case, I would appreciate it if you could let me know in the comments. Have a good video posting life! !!
