BobbinThe short version
- Under 25 MB: attach it to an email.
- Up to 1 GB: drop it into Slack.
- Anything larger, or for many viewers: upload to Google Drive, OneDrive or Dropbox and share the link, or upload to YouTube as Unlisted.

How big is a screen recording?
It depends on what's on screen more than on length. A mostly static recording (slides, a document, a code editor) was about 4 MB per minute in our test with Bobbin at 1080p. Full-screen video, scrolling and animations produce much larger files. So a 5-minute walkthrough is often small enough for email, and a 30-minute lecture usually isn't.
Keep recordings smaller
- Record a window or tab instead of a large or multi-monitor screen.
- Stick to 1080p at 30fps unless you need more. Higher resolutions and 60fps make bigger files.
- Avoid playing video in the background of a screen recording.
- Split long topics into several shorter recordings.
Share via Google Drive (works for any size)
- Download the recording from your recorder (in Bobbin, from the Library).
- Upload it to Google Drive.
- Right-click → Share. Add people, or set General access to "Anyone with the link" if that's appropriate.
- Copy the link and send it. Drive lets viewers play the video in the browser once it has processed.
The same works with OneDrive and Dropbox. For public or very long videos, YouTube's Unlisted setting gives you a link that doesn't appear in search.
Why Bobbin saves a file instead of a link
Bobbin never uploads your recordings and has no account or servers for video. You decide where the file goes and who sees it. The trade-off is that you share it yourself; if you need instant links with comments and analytics, a hosted tool like Loom fits better. See Loom alternative for that comparison.
