Import exported guides

Help

Hi, how to import guided exported as FFMPEG chapters to different project?
Or chapters extracted from MKV file?

I’d like to start rendering but need import chapters (to render splitted files), I exported from different project before
so I solved problem:
use
ffmpeg -i input.mp4 -f ffmetadata chapters.txt

then I made this script:

import re, json

def FFMETADATA_chapters_to_KDENLIVE_guides(file, offset=0, TIMEBASE=1000000000, FPS=25):
    # open file
    with open(file, 'r', encoding='utf-8') as f:
        txt = f.read().split('[CHAPTER]')[1:]  # Split based on '[CHAPTER]' and ignore the first part

    new_chaps = []
    for chap in txt:
        # Extract start time and title
        s = re.search(r'START=(\d+)', chap)
        t = re.search(r'title=(.*?)$', chap, re.MULTILINE)
        if s and t:
            comment = t.group(1)
            pos = int(s.group(1))
           
            # Convert start time to frames and apply offset
            frames = int(pos / TIMEBASE * FPS) + offset
            new_chaps.append({"comment": comment, "pos": frames, "type": 2})

    # Write the new chapters to a JSON file
    with open(file.rsplit('.', 1)[0]+'.json', 'w', encoding='utf-8') as out:
        json.dump(new_chaps, out, indent=4, ensure_ascii=False)

#------------USE SCRIPT HERE-------------------
FFMETADATA_chapters_to_KDENLIVE_guides('chapters.txt', offset=0, FPS=25)

adjust FPS etc. and edit project file in any notepad then paste generated guides in correct place.

I think this video contains what you’re looking for, I have used a method to import guides.
Please watch the full video. There are two file types of guides that can be exported into, that is json or csv file. (I used csv file format).
