よくある質問
What does Video Summarizer do?
You upload a short video and Gemini 2.5 analyzes both the audio track and the on-screen visuals to produce a concise summary of what happens and what's discussed.
What video formats and size can I upload?
Upload MP4, WebM, or MOV files up to 20 MB — roughly 5 to 10 minutes at typical bitrates. Larger or longer videos should be trimmed or compressed first.
Does it understand visuals, not just speech?
Yes. Unlike audio-only tools, it considers both the spoken content and the visual scene, so it can summarize demos or footage even when little is said.
How accurate is the summary?
It captures the main points and key visuals well. Fast-cut footage, dense detail, or poor audio can cause it to miss specifics, so check the source for anything critical.
Why is there a size and length limit?
The 20 MB cap keeps processing fast and reliable. For longer videos, compress the file or upload only the segment you need summarized.
Can I use the summary commercially?
Yes. The summary text is yours to use in notes, reports, or content. The free tier offers 5 uses per day with no signup; Pro is $19/month for more.
Is my uploaded video kept?
No. The clip is processed to generate the summary and then discarded — it isn't stored or used to train models.
