YouTube Transcription

Paste a YouTube URL and Speakly downloads the audio and transcribes it.

How to use

1. Click YouTube in the left sidebar — it is its own item, below Transcribe Media, not part of it
2. Click New Transcription to open Transcribe YouTube Video
3. Paste the link in the field ("Paste YouTube URL here...")
4. Set Video Language to the language spoken in the video
5. Click Transcribe Video

Limits

• Videos up to 2 hours; longer ones fail with Video is too long (… min). Maximum duration is 120 minutes for transcription.
• Over 8 minutes the audio is split into 9-minute chunks and merged back into one transcript — the dialog says "Supports videos up to 2 hours. Long videos are automatically split into chunks."
• Chunked videos keep their timestamps: each chunk's segments are shifted onto the full timeline and the ten seconds of overlap are trimmed, so a two-hour video has real times all the way through

Progress while it runs

The dialog names the stage it is in and, once transcription starts, draws a real bar with a percentage: Downloading audio..., then Converting format..., then Transcribing (may take a while for long videos)....

• Preparing the audio… — a second line under the stage, while the audio is read and, for a video long enough to be split, re-encoded into parts. On a two-hour video that happens before any words appear.
• Part x of y — shown while each part is transcribed, with the percentage climbing next to the stage.
• Complete! — the parts have been merged into the final transcript.

With the Local Model (On-Device) engine the percentage also moves inside each part, because the local engine reports its own decoding progress. Cloud engines answer a part in a single request and cannot report anything in between, so there the bar advances part by part.

The result

• The video title and duration in the dialog header, plus the word count
• The transcript as timestamped lines, grouped so a line ends where the sentence ends
• AI actions: Flashcards, FAQ, Ask, Translate
• Copy All copies the whole transcript; Close dismisses the dialog

Timestamps and the player

The video is embedded above the transcript, and every timestamp is a button — its tooltip is "Jump to this moment" — that moves the player to that second and plays from there. The player appears on the transcript view only; it is hidden on Flashcards, FAQ, Ask and Translate, where it would keep playing behind the text.

• Lines are grouped at sentence ends instead of one line per engine segment. Speech without punctuation still breaks: a group is cut after 320 characters or 30 seconds.
• A group keeps the start of its first segment, so a click lands where the sentence begins.
• If the embedded player is not yet answering, the click reloads the embed at that second instead — slower, but it always lands.
