- Install Python 3.9 or higher
- (ONLY to download videos, if only MP3 is wanted skip this) Install the ffmpeg tool for your platform
- Install requirements:
python -m pip install -r requirements.txt
- Copy the scripts to the folder you want to download files to
Will request the video URL. You can use the URL in the browser input field, or any or the ones provided by YT like when pressing YT, or when right clicking on the video and using one of the "Copy URL" options.
It will also ask if you want only the audio, in which case only an mp3 will be provided, at the highest available bit rate.
The video stream of highest resolution will be downloaded. Sometimes that video is not in progressive video format and the resulting MP4 will not contain an audio stream. In that case the script will also download the audio in an MP3, resulting in two files being downloaded, one with the video and one with the audio. Then the script will try to run the merge.ps1 Microsoft Powershell script to merge both into a single video file that will have the _mix suffix.
If the video description in YT contains lines that conform to the following format, they will be takes as the video index. Other lines that do not have this format are ignored, so thre can be anything written before, after or in between the index lines:
<start> - <end> - <title>
For example:
1:00 - 1:30 - Billie Jean - Michael Jackson
Start and end must be time expressed in HH:MM:SS.000 format, the hours and miliseconds being optional. In the example above, the time period expressed is that between one minute and one minute and thirty seconds. The time format is quite permissive and will understand 1:30 as minute 1 and 30 seconds, and also 1:3:1 as hour one, minute three and one second.
An aditional file containing the information of the first three fields in CSV format will be produced. Notice that each line can contain other elements after the third one using the - as delimiter. Those extra columns will be ignored.If the video's description does not follow the format, the chapter information can be also created manually in a CSV format with a header line start,end,song with any text editor, and naming it with the same base name of the MP4 file and .csvextension will be directly used by the split_video.ps1 script as explained in the next chapter.
The output will include the description of the file as found in YT, and progress indication of each download and of the video-audio merging process if required.

This may take some time. Do not interrupt the process...

To merge video and audio run the merge.ps1 script from a Windows PowerShell command line witht the -file parameter indicating the .mp4 file name. This only needs to be done for non-progressive videos, if the yt.py script produced separate .mp4 and .mp3 files it will try to run this script automatically; so you won't usually need to run this script manually.
./merge.ps1 -file yt-video-test.mp4
The script will produce a new file with the _mix suffix in the name (f.e. yt-video-test_mix.mp4)
This is a PowerShell script that has to be run from a Windows PowerShell command line. It will take a MP4 file and CSV file by the same base name, and split the video in separate files, one for each chapter declared in the CSV file. Each file will be named by the value of the third field, replacing spaces by dashes. In the example used in a previous chapter, an MP4 file named Billie_Jean.mp4 would be produced, discarding all the other footage of the video except that between 1:00 and 1:30 time.
You can provide a file with the _mix suffix if that is what the yt.py script produced as result of merging video and audio, and it will use the CSV of the file without the _mix as produced by the yt.py script.
./split_video.ps1 -file jam-oviedo-20-31-7-2024-javi-queen_mix.mp4
