什么平台就是抖音，用OBS录屏生成的.MP4文件,文件名就是开始录制的时间，一样想生成个时间字幕

gyc0123 commented 2 weeks ago

抖音没字幕功能吧，要是视频语音转文字或者srt，可以用科大讯飞的ai

Douyin doesn’t have a subtitle function. If you want to convert video speech to text or SRT, you can use iFlytek’s AI

How about letting chatgpt write one, read the time from the file name, and then add one line of time subtitles every minute. Adjust the datetime library string to convert the time, and then loop the output time in srt format. Here is chatgpt's answer:

To add time subtitles to your videos, you can do it using some automated scripts or tools. The exact steps depend on your operating system and the tools you use. The following is a rough process using ffmpeg and Python scripts to generate time subtitles. ffmpeg is a powerful video processing tool that can be used to add subtitles and perform other video editing operations.

1. Install necessary tools

First, make sure you have the following tools installed:

ffmpeg: used for video processing.
Python: used to write scripts that generate subtitles.

You can install them with the following command:

Install ffmpeg (if not already installed):
- Windows: Download link
- macOS: brew install ffmpeg
- Linux: sudo apt install ffmpeg (or use another package management tool)
Install Python (if not installed): Download and install from Python official website.

2. Python script to generate subtitle files

Next, we can write a Python script that will read the timestamp of the video file and generate a subtitle file in .srt format. Insert a subtitle every minute, showing the current time of the video.

Sample Python script:

import os
import datetime

# Enter the video file path
video_filename = "your_video_file.mp4"

# Get the duration of the video
import subprocess

def get_video_duration(filename):
    result = subprocess.run(
        ['ffmpeg', '-i', filename, '-v', 'quiet', '-print_format', 'json', '-show_format'],
        stdout=subprocess.PIPE,
        stderr=subprocess.PIPE
    )
    output = result.stderr.decode()
    duration_str = [line for line in output.splitlines() if "duration" in line][0]
    duration_seconds = float(duration_str.split('=')[1])
    return duration_seconds

# Generate subtitle file
def create_subtitles(video_filename):
    duration = get_video_duration(video_filename)
    subtitle_filename = video_filename.rsplit('.', 1)[0] + '.srt'

    with open(subtitle_filename, 'w') as f:
        subtitle_index = 1
        current_time = 0
        while current_time < duration:
            start_time = str(datetime.timedelta(seconds=current_time))
            end_time = str(datetime.timedelta(seconds=current_time + 60))
            # Format to srt time format (hh:mm:ss,SSS --> hh:mm:ss,SSS)
            start_time = start_time[:-3].replace('.', ',') # Delete. and format
            end_time = end_time[:-3].replace('.', ',')

            # Time subtitle content
            subtitle_text = start_time
            f.write(f"{subtitle_index}\n")
            f.write(f"{start_time} --> {end_time}\n")
            f.write(f"{subtitle_text}\n\n")

            subtitle_index += 1
            current_time += 60

    print(f"Subtitle file has been generated: {subtitle_filename}")

create_subtitles(video_filename)

3. Add subtitles to video

After generating subtitle files, the next step is to add these subtitle files to the video. Subtitles can be embedded into videos using the ffmpeg command.

Use `ffmpeg` to add subtitles:

ffmpeg -i input_video.mp4 -i subtitles.srt -c:v copy -c:a copy -c:s mov_text output_video.mp4

input_video.mp4 is the original video file.
subtitles.srt is the subtitle file you generated.
output_video.mp4 is a new video file that outputs subtitles.

4. Automated operations

If you have multiple files to process, you can modify the script to loop through all .mp4 files in a directory and process them in batches:

import glob

def process_videos_in_directory(directory):
    video_files = glob.glob(os.path.join(directory, "*.mp4"))
    for video_filename in video_files:
        create_subtitles(video_filename)
        print(f"Processed: {video_filename}")

#Set the directory where the video file is located
video_directory = "path/to/your/videos"
process_videos_in_directory(video_directory)

In this way, the script will automatically process all .mp4 files in the specified directory, generate and add time subtitles.

Summary

Extract video duration via ffmpeg.
Use a Python script to generate subtitle files, generating one time subtitle every minute.
Use ffmpeg to embed subtitles into videos.

In this way, you can add time subtitles to videos in batches. If you have other specific needs or want to optimize the script further, feel free to let me know!

config/config.ini里面有个生成时间字幕文件 = 否 把否改成是

这个机器人好尴尬啊，我说错了都删不掉

There is a Generate time subtitle file = No in config/config.ini Change no to yes

是的，这个项目有这个生成字幕功能。所以我想借鉴这个功能，使用到类似的 2024-11-12 23-39-45.mp4 文件上。用obs录制出来的MP4文件，文件名是开始时间，读取视频时长，生成一样时间长度的时间字幕文件。微信截图_20241113194331

Yes, this project has this subtitle generation function. So I want to borrow this feature and use it on a similar 2024-11-12 23-39-45.mp4 file. For MP4 files recorded with obs, the file name is the start time. Read the video duration and generate a time subtitle file of the same length. WeChat screenshot_20241113194331

这是那段代码，while循环输出一行字幕sleep 1秒，你也可以for循环秒数 main.py

def generate_subtitles(record_name: str, ass_filename: str, sub_format: str = 'srt') -> None:
    index_time = 0
    today = datetime.datetime.now()
    re_datatime = today.strftime('%Y-%m-%d %H:%M:%S')

    def transform_int_to_time(seconds: int) -> str:
        m, s = divmod(seconds, 60)
        h, m = divmod(m, 60)
        return f"{h:02d}:{m:02d}:{s:02d}"

    while True:
        index_time += 1
        txt = str(index_time) + "\n" + transform_int_to_time(index_time) + ',000 --> ' + transform_int_to_time(
            index_time + 1) + ',000' + "\n" + str(re_datatime) + "\n\n"

        with open(f"{ass_filename}.{sub_format.lower()}", 'a', encoding=text_encoding) as f:
            f.write(txt)

        if record_name not in recording:
            return
        time.sleep(1)
        today = datetime.datetime.now()
        re_datatime = today.strftime('%Y-%m-%d %H:%M:%S')

This is the code. The while loop outputs a line of subtitles and sleeps for 1 second. You can also use the for loop to count the seconds. main.py
def generate_subtitles(record_name: str, ass_filename: str, sub_format: str = 'srt') -> None:
index_time = 0
today = datetime.datetime.now()
re_datatime = today.strftime('%Y-%m-%d %H:%M:%S')

def transform_int_to_time(seconds: int) -> str:
    m, s = divmod(seconds, 60)
    h, m = divmod(m, 60)
    return f"{h:02d}:{m:02d}:{s:02d}"

while True:
    index_time += 1
    txt = str(index_time) + "\n" + transform_int_to_time(index_time) + ',000 --> ' + transform_int_to_time(
        index_time + 1) + ',000' + "\n" + str(re_datatime) + "\n\n"

    with open(f"{ass_filename}.{sub_format.lower()}", 'a', encoding=text_encoding) as f:
        f.write(txt)

    if record_name not in recording:
        return
    time.sleep(1)
    today = datetime.datetime.now()
    re_datatime = today.strftime('%Y-%m-%d %H:%M:%S')
