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 99 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: one recording of up to 45 minutes
How to Generate a Video Description
- Upload or paste a link: Drop an MP4, WebM, MOV, AVI, MKV, WMV, and FLV 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.

- vs Descript: Descript’s free plan gives you 60 minutes a month; ScreenApp’s free plan is one recording of up to 45 minutes with no monthly cap on top of that.
- vs ChatGPT: ChatGPT does not take a video file the way ScreenApp does. You have to transcribe the video elsewhere first and paste the text in, and OpenAI’s own help centre notes that an uploaded video may not analyze the entire video or accurately interpret its audio. ScreenApp transcribes the video and writes the draft in one step.
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.
FAQ
What is a video description generator?
It is a tool that transcribes a video and turns the transcript into a draft description with timestamps, ready to edit and post to YouTube, TikTok, or Instagram.
How does it work?
ScreenApp transcribes the audio, AI reads video frames, not just the audio, and finds the chapter breaks. From that it drafts a description you can edit before publishing.
Can I use this for free?
Yes. The free plan includes one recording of up to 45 minutes, with the transcript and AI chat on that recording. Paid plans start at $19 a month billed annually.
Does it generate timestamps automatically?
Yes, chapters with timestamps. Check them against the video before you publish, since accuracy depends on how clearly people are speaking.
What video formats are supported?
Upload MP4, WebM, MOV, AVI, MKV, WMV, and FLV files up to 2 GB. You can also 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, or upload a transcript file if you already have one.
How accurate is the transcript?
Accuracy depends on the audio: a clear voice track transcribes well, and background noise or overlapping speakers will leave gaps. See how we measure accuracy for the method and the current numbers.
Can I make descriptions for different platforms from one upload?
Yes. Pick YouTube, TikTok, Instagram, or a general format and ScreenApp adjusts the length of the draft to fit. You can generate more than one from the same upload.
How many languages does it support?
Transcription covers 99 languages, so you can generate a description in a different language from the one spoken in the video.
Is my video data secure?
Videos are encrypted in transit, encrypted at rest with AES-256, and not used to train AI models. ScreenApp’s controls are published on its trust center, which lists SOC 2 Type 2.
How is this different from ChatGPT?
ChatGPT cannot take a video file directly the way ScreenApp does: you would need to transcribe it elsewhere and paste the text in, and OpenAI’s own help centre says an uploaded video may not analyze the entire video or accurately interpret its audio. ScreenApp transcribes the video and drafts the description in one step.
