X Post / Twitter Video Transcription

Video is everywhere on X now — product launches, founder threads, breaking-news clips, and long-form uploads from Premium accounts. But X gives you no exportable transcript and only patchy auto-captions, so all that spoken content is locked inside the video. You can't search it, quote it accurately, caption it properly, or turn it into anything else.

Castmagic fixes that. Paste the URL of any public X post that contains a video and we pull the audio and return a full, timestamped transcript in minutes. From there our AI turns the clip into ready-to-post captions, a recap thread, a blog write-up, pull-quotes, and short social clips — so a single X video becomes a week of content.

Why transcribe a video from X

X has become a serious video platform — Premium accounts can upload long videos, and some of the most valuable commentary, demos, and interviews now live as native X posts rather than on YouTube. The problem is that X treats video as disposable: no transcript, no dependable captions, no easy way to get the words out of the clip.

Whether you're a creator who wants to reuse your own videos, a marketer quoting a founder's post, a journalist citing a clip, or a researcher who needs the exact wording, the first thing you need is an accurate transcript. Castmagic turns an X post link into one in minutes.

What Castmagic produces from an X video

Every X video you process returns: a full transcript with timestamps, ready-to-use captions (SRT or plain text) for re-uploading the clip with subtitles, a recap thread drafted from the transcript, a pull-quote sheet, a blog-post or newsletter draft, and short clip suggestions for the strongest moments.

Captions matter most here — the majority of X video is watched on mute, so subtitles directly drive watch-time and reach. Castmagic gives you accurate, properly-timed captions instead of X's hit-or-miss auto-captions.

X posts vs. Spaces vs. just downloading

This tool is for the video attached to an X post. If you want to transcribe a live audio conversation, use our Twitter Spaces transcription tool, which is built for X Spaces recordings. If you only want to save the video file without a transcript, our Twitter / X video downloader does exactly that. Pick the tool that matches what you are starting from.

Which X links work

Castmagic works with any public X or Twitter post that contains a video — single videos, videos inside threads, and long-form Premium uploads. Posts from protected (private) accounts, deleted posts, and posts without any video can't be transcribed, since there's no public audio to pull.
