A GUI-EDITOR for editing videos Supports local video files and YouTube URLs with smart segment-aware downloading. clipping videos into segment ussing timestamps from a CSV file.

Features

Core Clipping

• Timestamp-based clipping — reads data/time.csv and splits video into segments at original resolution (no cropping or scaling)
• Batch processing — queue multiple videos and process them all at once
• Queue management — add, list, remove, and clear videos from the processing queue

YouTube Support

• YouTube Direct — paste a YouTube URL, pick a format, and download only the segments you need

• Comments extraction — download video comments (with optional max count)
• Comment count — get total comment count for a video
• Duplicate detection — tracks previously extracted videos in output/extracted.txt

Audio & Vocals

• Vocals-only video — mux isolated vocals back into the video as a separate output
• Silence remover — remove silent regions from audio files with configurable thresholds

Captioning

• Audio captioner — transcribe speech with Whisper, translate to any language, and render captions on video
• Multiple Whisper models — tiny, base, small, medium, large
• Google Translate integration — auto-translate transcribed text to target language

Setup

Prerequisites

Creating timestamps

Create data/time.csv with one timestamp pair per line:

02:20 – 02:34
06:51 – 07:46
08:34 – 08:46

Format: MM:SS - MM:SS or HH:MM:SS - HH:MM:SS. Line numbers, en-dashes (–), em-dashes (—), and hyphens (-) are all supported as separators.

YouTube Direct workflow

1. Select [8] YouTube Direct
2. Paste the YouTube URL
3. View available formats with size estimates (full video vs clips only)
4. Pick a format ID or press Enter for best quality
5. Segments are downloaded and clipped to output/

Playlist Download workflow

1. Select [13] Playlist Download
2. Paste the YouTube playlist URL
3. Select a download folder via the folder picker
4. View available resolutions with total/average size estimates
5. Pick a resolution (required, no auto-select)
6. Videos download sequentially with live progress

Custom Playlist Download

1. Paste the YouTube playlist URL
2. Enter a starting episode number (e.g., 1812)
3. The script extracts episode numbers from video titles and filters from that episode onward
4. If title matching fails, you can paste the exact video link instead — it finds the position and downloads from there
5. Select folder and resolution, then download

Vocal Separation

When processing videos (options 5, 6, or 8), you'll be asked if you want to separate vocals. If enabled:

• Each clip gets vocals isolated via demucs-onnx

Notes

• Output clips are saved at original resolution with no quality loss
• YouTube segment downloading uses ffmpeg sub-processes for fast extraction
• The tool caches downloaded YouTube source files in output/_temp/ to avoid re-downloading
• Whisper model files are downloaded on first use and cached locally
