Submagic vs Opus Clip: two different jobs
People search for Submagic vs Opus Clip as if the tools were rivals. Read their own pages and they start from different places. OpusClip's help centre describes importing a long video and getting clips back. Submagic's pages lead with animated captions and text-based editing, and sell long-video clipping, which it calls Magic Clips, as an add-on.

Opus Clip or Submagic: a decision rule
- Your problem is "I have a 60-minute episode and no idea which 40 seconds to post": OpusClip, or KeyMo. Submagic's listed video limits stop at 30 minutes on Business.
- Your problem is "I already cut the clip and the captions look flat": Submagic. Its pages are built around caption templates, Brand Kit fonts and colours, and editing by transcript.
- You clip long videos and want captions in the same step: OpusClip or KeyMo, since both caption inside the clipper. Paying for both OpusClip Starter and Submagic Starter is $34 a month, against $12 for KeyMo Starter.
- You want captions on dozens of short videos a month and nothing else: compare Submagic's video counts, not minutes, because it meters by video.
Worked example: a weekly 45-minute episode
Four 45-minute episodes are 180 source minutes a month. Here is how each tool handles that.
| Tool | What the limits say | Monthly price |
|---|---|---|
| OpusClip | 180 credits at 1 per minute. Starter's 150 is short, so Pro with 300 credits | $29 monthly, or $14.50 a month billed yearly |
| Submagic | A 45-minute video is over the 30-minute Business cap, so the episode would have to be cut first | Not applicable as listed |
| KeyMo | 180 of the 300 minutes on Starter | $12 |
If you cut the clips yourself, the Submagic maths changes. Eight clips from each of the four episodes is 32 videos a month. Starter covers 15 videos, so you need Pro, which lists 40 videos: $39 monthly or $23 a month billed yearly. Every clip must also fit the plan's length cap, which is 5 minutes on Pro and easily holds a 90-second clip.
Where Submagic is stronger
- Caption focus. Its pages describe 35+ animation templates that highlight word by word, a custom words dictionary and Brand Kit fonts and colours.
- Editing by transcript: cutting words in the transcript cuts the video, with silence removal, auto zoom, B-roll and eye contact correction listed on its comparison table by plan.
- Higher ceiling on export: Business lists 4K at 60 fps.
- A public API with documented rate limits, and per-member pricing with Business offering unlimited users in its mobile comparison view.
- No watermark on any of its paid plans.
Where OpusClip is stronger
- Long inputs. Up to 10 hours, against Submagic's 2, 5 and 30 minutes.
- Clip finding is the core product, not an add-on, and its help centre gives clip-count guidance by video length.
- A free plan to test with, though clips are watermarked, cannot be edited and stop being exportable after 3 days.
- Many import sources, a social scheduler and team workspace on Pro.
