For editing Reels and Shorts, CapCut is the top all-around pick - its free tier exports clean 1080p video without watermarks, generates automated captions, and provides pre-built 9:16 vertical templates. If your weekly workflow involves chopping long-form recordings (podcasts, livestreams, webinars) into multiple short clips at once, OpusClip is the better choice because it automatically identifies the best highlights.

This guide is part of our tool recommendation series. We verified these details on October 8, 2026.

3 Best options: free, all-around winner, and advanced

Pricing reflects official tiers as of October 8, 2026. OpusClip also offers a Starter plan from $15 per month, while its free tier includes a watermark. We recommend Descript (from $24 per month) primarily for podcast workflows, where editing is handled directly through text transcripts.

Our clip selection test

Neither OpusClip nor CapCut offers a public API for raw testing, so we evaluated the underlying clipping logic directly: we passed a transcript of a 4-minute episode about cutting home electricity costs with timestamps into Gemini 3.8 Flash via API (we tested it in Polish). We tucked 3 strong hook-worthy moments - an always-on set-top box consuming roughly $30 a year, an electric kettle, and off-peak night rates - between small talk about weather and standard “subscribe” callouts. The model identified all three segments, kept each clip within the 20-45 second window (38, 38, and 25 seconds), and cut cleanly on sentence boundaries. Its only hallucination: the generated hook claimed “40% off laundry”, even though the 40 percent figure in the source audio referred to off-peak kilowatt-hour pricing. The API test cost $0.01 USD.

Our takeaway: AI excels at identifying key soundbites, but you must always review captions and hook headlines before publishing, as that is where numbers get garbled.

How to edit a short-form video in 4 steps

1. Record vertically, or set your canvas in CapCut to 9:16 (crop horizontal footage so the speaker stays centered).
2. Cut out the opening 2 seconds of silence or greetings - your short needs to jump straight into the hook.
3. Generate auto-captions, then review and correct proper nouns, technical terms, and numbers.
4. Pick background audio from the in-app library or directly inside the platform where you publish to avoid copyright mutes.

Frequently asked questions

Can you edit short videos for free without a watermark?

Yes. CapCut Free exports clean 1080p footage without a watermark as long as you do not apply premium templates, filters, or audio tracks flagged with a crown icon. See our full breakdown in CapCut without a watermark.

Does CapCut support auto-captions?

Yes, CapCut includes multi-language auto-transcription in its free tier with standard usage limits. You should still review proper nouns and numerical values manually.

Does OpusClip handle non-English languages well?

OpusClip relies on speech-to-text recognition to detect hooks and highlights. Its accuracy depends heavily on audio clarity and language support. Before upgrading to a paid tier, upload a sample recording to the free plan to inspect the caption accuracy and clip choices on your actual footage.
