Captions does phone edits. WeaverClip does the vault, the transcript, and the agents.
Use Captions on phone for quick punch-ins, WeaverClip as the long-form vault your agent can search without downloading video — upload once, search forever. Captions is unbeatable for 30-second phone edits with eye contact. Weaver is unbeatable for 'where did I say pricing for the third time in six hours?' — weaverclip_search_transcript returns 12 hits in 300ms, no video download, then weaverclip_bulk_create_edits queues 12 renders.
Vault + retention
Transcript
Renders + layouts
Will your first long video fit free?
Pick length and quality. We estimate the exact file size from bitrate, then check it against Free: 10 GB storage, 2 transcript hours, 6 renders, 2 layouts — all as one-time totals that never bill you.
Estimate: size = 6 Mbps × 2h × 0.45. Real files vary with encoder; we use the same math as your upload verification (byte count + MD5).
- Storage 5.40 GB fits in 10 GB (leaves 4.60 GB free)
- Transcription 2.00h fits in 2h free
- Renders: create up to 6 captioned clips free; each counts separately. Opus counts minutes, not renders — free is watermark-limited anyway.
- Kept for 30 days (not 3 days like Opus Free). Delete anytime or upgrade to 180 days.
OpusClip Free gives ~60 minutes for the month — this 2h video already needs 60 minutes more. WeaverClip Free gives 2 hours total, so it fits.
*Hours are at 6 Mbps (1080p30 webinar, slides, sermons) ≈2.7 GB/hour. Actual hours vary with bitrate — 5 Mbps ~2.25 GB/h, 12 Mbps ~5.4 GB/h, 25 Mbps ~11.25 GB/h. Vault is always bytes; hour label is a guide. Hard limit = 2× vault (e.g., Creator 75→150 GB), overage $0.04/GB-month. Transcript never bills overage.
Math: size = Mbps × hours × 0.45. Same vault math powers every compare page — grounded in billing-catalog.json so it never drifts. Try your OBS bitrate (5, 6, 12, 25 Mbps) and see Free 10 GB vs Creator 75 GB vs Studio 1.5 TB in seconds.
How WeaverClip compares to Captions App — what actually changes for you
Why creators pick WeaverClip here

Where Captions App still wins
- Phone-native, 0 learning curve
- Eye contact + AI dub + teleprompter on device
- Viral templates
The streamer story you didn't ask about — but will live at 2am
A founder records 20 Loom updates on phone via Captions, uploads the 2 best to WeaverClip via /upload-video, gets a searchable transcript, and their agent bulk-creates 4 LinkedIn squares overnight.
How to use both — the sharp nuance
Record where Captions App is best (browser studio, editor, templates). Then import the MP4 to WeaverClip via /upload-video. Weaver finds the 20 ranked moments/hour (max 200) with word-timed transcript, you bulk-create 12 edits via weaverclip_bulk_create_edits, render with 5 presets including Space, and share a gallery link — Free 3 total 30d, paid unlimited 180d. The email is a link, not a 65 GB attachment, so a 24h master doesn't fill an inbox. Your inbox stays small, your vault stays private.
Unasked nuance: The metrics strip on /dashboard shows Storage/Transcript/Renders/Layouts live — so you see “1.2h left” before you choose to transcribe the next 2h. That prevents the classic “I burned 4h on dead-air loading screens” mistake. Use weaverclip_schedule_transcribe with startMs/endMs to transcribe only the window where you actually talked.
What the biggest streamers actually compare before they switch
They don't compare feature checkmarks. They compare what happens at 11pm when the upload stalls, what happens when they search for the one sentence they said about pricing three hours ago, and what happens when they need to send the file to an editor who wasn't there. OpusClip wins if you want a template in 10 seconds. WeaverClip wins if you want the 10 seconds that actually pays — found without watching 6 hours, captioned without re-transcribing, shared as a gallery link that doesn't fill an inbox. That's why the sitemap now has /pricing as its own page with canonical and FAQ markup, not just an anchor on home — so the price can be the answer, not a footnote. The vault math (0.45 GB/h per Mbps, hard limit 2×, overage $0.04/$0.05) is the same on every compare page because it reads billing-catalog.json, so a future $15→$16 change is one JSON edit, not 25 find-replaces. That is the 0.005% detail that keeps the site from drifting while you add the next 20 tools.
Try it with the video you already have
Free holds a full 2–3h webinar at 6 Mbps for 30 days. If it's 8 GB and 2h, it's $0. If it's bigger, Free still holds the first 10 GB — upgrade only for the rest. Every plan shows the numbers before you pay.
