Source Code

Gettr Transcribe + Summarize (MLX Whisper)

Quick start

# 1. Parse the slug from the URL (just read it — no script needed)
#    https://gettr.com/post/p1abc2def  → slug = p1abc2def
#    https://gettr.com/streaming/p3xyz → slug = p3xyz

# 2. Get the video URL
#    For /post/ URLs: use the extraction script
python3 scripts/extract_gettr_og_video.py "<GETTR_POST_URL>"

#    For /streaming/ URLs: use browser automation directly (extraction script is unreliable)
#    See Step 1 below for browser automation instructions

# 3. Run download + transcription pipeline
bash scripts/run_pipeline.sh "<VIDEO_URL>" "<SLUG>"

To explicitly set the transcription language (recommended for non-English content):

bash scripts/run_pipeline.sh --language zh "<VIDEO_URL>" "<SLUG>"

Common language codes: zh (Chinese), en (English), ja (Japanese), ko (Korean), es (Spanish), fr (French), de (German), ru (Russian).

This outputs:

./out/gettr-transcribe-summarize/<slug>/audio.wav
./out/gettr-transcribe-summarize/<slug>/audio.vtt

Then proceed to Step 3 (Summarize) to generate the final deliverable.

Workflow (GETTR URL → transcript → summary)

Inputs to confirm

Ask for:

GETTR post URL
Output format: bullets only or bullets + timestamped outline
Summary size: short, medium (default), or detailed
Language (optional): if the video is non-English and auto-detection fails, ask for the language code (e.g., zh for Chinese)

Notes:

This skill does not handle authentication-gated GETTR posts.
This skill does not translate; outputs stay in the video's original language.
If transcription quality is poor or mixed with English, re-run with explicit --language flag.

Prereqs (local)

mlx_whisper installed and on PATH
ffmpeg installed (recommended: brew install ffmpeg)

Step 0 — Parse the slug and pick an output directory

Parse the slug directly from the GETTR URL — just read the last path segment, no script needed:

https://gettr.com/post/p1abc2def → slug = p1abc2def
https://gettr.com/streaming/p3xyz789 → slug = p3xyz789

Output directory: ./out/gettr-transcribe-summarize/<slug>/

Directory structure:

./out/gettr-transcribe-summarize/<slug>/audio.wav
./out/gettr-transcribe-summarize/<slug>/audio.vtt
./out/gettr-transcribe-summarize/<slug>/summary.md

Step 1 — Get the video URL

The approach depends on the URL type:

For `/post/` URLs — Use the extraction script

Run the extraction script to get the video URL from the post HTML:

python3 scripts/extract_gettr_og_video.py "<GETTR_POST_URL>"

This prints the best candidate video URL (often an HLS .m3u8) to stdout.

If extraction fails, ask the user to provide the .m3u8/MP4 URL directly (common if the post is private/gated or the HTML is dynamic).

For `/streaming/` URLs — Use browser automation directly

Do not use the extraction script for streaming URLs. The og:video URL from static HTML extraction is unreliable for streaming content — it either fails outright or the download stalls and fails near the end.

Instead, use browser automation to get a fresh, dynamically-signed URL:

Open the GETTR streaming URL and wait for the page to fully load (JavaScript must execute)

Extract the og:video meta tag content from the rendered DOM:

document.querySelector('meta[property="og:video"]').getAttribute('content')

Use that fresh URL for the pipeline in Step 2

If browser automation is not available or fails, see references/troubleshooting.md for how to guide the user to manually extract the fresh URL from their browser.

Step 2 — Run the pipeline (download + transcribe)

Feed the extracted video URL and slug into the pipeline:

bash scripts/run_pipeline.sh "<VIDEO_URL>" "<SLUG>"

To explicitly set the language (recommended when auto-detection fails):

bash scripts/run_pipeline.sh --language zh "<VIDEO_URL>" "<SLUG>"

The pipeline does two things:

Downloads audio as 16kHz mono WAV via ffmpeg
Transcribes with MLX Whisper, outputting VTT with timestamps

If the pipeline fails with HTTP 412 (stale signed URL)

This error occurs with /streaming/ URLs when the signed URL has expired. If browser automation returned a stale URL, retry by re-running browser automation to get a fresh URL, then retry the pipeline.

If browser automation is not available or fails, see references/troubleshooting.md for how to guide the user to manually extract the fresh URL from their browser.

Notes:

By default, language is auto-detected. For non-English content where detection fails, use --language.
If too slow or memory-heavy, try smaller models: mlx-community/whisper-medium or mlx-community/whisper-small.
If quality is poor, try the full model: mlx-community/whisper-large-v3 (slower but more accurate).
If --word-timestamps causes issues, the pipeline retries automatically without it.

Step 3 — Summarize

Write the final deliverable to ./out/gettr-transcribe-summarize/<slug>/summary.md.

Pick a summary size (user-selectable):

Short: 5–8 bullets; (if outline) 4–6 sections
Medium (default): 8–20 bullets; (if outline) 6–15 sections
Detailed: 20–40 bullets; (if outline) 15–30 sections

Include:

Bullets (per size above)
Optional timestamped outline (per size above)

Timestamped outline format (default heading style):

[00:00 - 02:15] Section heading
- 1–3 sub-bullets

When building the outline from VTT cues:

Group adjacent cues into coherent sections.
Use the start time of the first cue and end time of the last cue in the section.

Bundled scripts

scripts/run_pipeline.sh: download + transcription pipeline (takes a video URL and slug)
scripts/extract_gettr_og_video.py: fetch GETTR HTML and extract the og:video URL (with retry/backoff)
scripts/download_audio.sh: download/extract audio from HLS or MP4 URL to 16kHz mono WAV

Error handling

Non-video posts: The extraction script detects image/text posts and provides a helpful error message.
Network errors: Automatic retry with exponential backoff (up to 3 attempts).
No audio track: The download script validates output and reports if the source has no audio.
HTTP 412 errors: Occurs with /streaming/ URLs when the signed URL has expired. Re-run browser automation to get a fresh URL (see Step 1); if that fails, see references/troubleshooting.md.

Troubleshooting
