Turn a Video Into a Description
ScreenApp transcribes your video, finds the chapter breaks, and writes a description you can edit and post. Upload a file, paste a link, or bring a transcript you already have.
What you get:
- A transcript in 100+ languages
- chapters with timestamps
- A draft description for YouTube, TikTok, Instagram, or LinkedIn that you can edit before posting
- Export the transcript as PDF, DOCX, TXT, SRT and VTT
- Free plan: 2 transcriptions of recordings up to 45 minutes each
How to Generate a Video Description
- Upload or paste a link: Drop an MP4, M4V, MOV, AVI, WEBM, MKV, FLV, TS, MTS, M2TS, 3GP, 3GPP, 3G2, WMV, ASF, VOB, OGV, RM, RMVB, MPG, MPEG, M2V, F4V, MXF file into ScreenApp, or paste a link from YouTube, Vimeo, TikTok, Instagram, Facebook and most other public video links (Twitch, Loom, Dropbox, Google Drive, Pinterest, X, Threads, Douyin, Kuaishou, Bilibili) through a generic importer. You can also upload a transcript file if you have one.
- Pick a platform: Choose YouTube, TikTok, Instagram, or a general format so the draft is the right length for where you are posting it.
- Read and edit the draft: ScreenApp transcribes the video and writes a description with timestamps. Check it against what is actually said in the video, then copy it to your platform.
The description is only as good as the transcript underneath it. A clear voice track gives a clean transcript and an accurate description; heavy background noise or overlapping speakers will leave gaps. See how we measure accuracy.

Who Generates Video Descriptions With ScreenApp
YouTubers and video creators upload a video and get a transcript with timestamps to build a chapter list, instead of scrubbing back through the footage to note when each topic starts.
Social media managers turn the same upload into a shorter draft for TikTok or Instagram and a longer one for YouTube, so one recording covers several platforms.
Content marketers and agencies transcribe webinars and product demos and use the transcript to write descriptions and show notes for several videos without re-watching each one.
Educators and course creators get a timestamped transcript for each lesson, which doubles as a reference for students and a starting point for a video description on a course platform.
Podcasters upload a video episode and use the transcript and chapter markers to write the show notes and the YouTube description in the same pass.
