Can 2short.ai take an MP4 file I recorded myself?

Its homepage describes pasting a YouTube link, with Google Drive and public URL imports on Lite and above. It does not mention uploading a file from your computer, so check inside the app. OpusClip and KeyMo both accept uploaded files.

Is 2short.ai really free compared with OpusClip's free plan?

2short.ai's Starter plan is free with 30 minutes of AI video analysis a month, though a banner on the same page says 15. OpusClip's free plan gives 60 credits a month, adds a watermark, and clips can no longer be exported after 3 days.

Which costs less per month, 2short.ai or OpusClip?

2short.ai Lite is $9.90 and OpusClip Starter is $15. The allowances are measured differently, 5 hours of analysis against 150 credits at 1 credit per source minute, so confirm how your own videos will be counted.

Why does 2short.ai say it only works on videos with captions?

Its FAQ says the tool can only process videos that have captions, and that YouTube auto-generates captions for most videos. A video with no captions available may be rejected, so test one before relying on it.

Do the clips from OpusClip or 2short.ai carry a watermark?

OpusClip's free plan and trial exports include its watermark, and Starter and Pro list watermark removal. 2short.ai's features section says exports have no watermarks but does not say which plans that covers.

Which of these handles a 90-minute interview best?

OpusClip and KeyMo both take it as an upload. It would use 90 OpusClip credits or 90 KeyMo minutes. 2short.ai does not publish a length limit or mention file uploads, so check in the app first.

Comparison

Opus Clip vs 2short AI: what each one accepts and what it costs

By the KeyMo team · Updated October 11, 2026

The main difference between Opus Clip and 2short AI is how you get a video in. 2short.ai's homepage describes pasting a YouTube link, with Google Drive and public URL imports from its $9.90 Lite plan. OpusClip also accepts local files of up to 10 hours. KeyMo takes MP4 and MOV uploads of 5 minutes to 3 hours from $12 a month, with no watermark.

Opus Clip vs 2short AI at a glance

Both tools turn a long video into short vertical clips, so the useful questions are practical ones. What can you feed in, what does the free plan really give you, and what happens to the file you export? The table below answers those from each vendor's own pages, with KeyMo added as a third column. Prices are in US dollars and were read on 2026-10-11, so check the vendor before you pay.

Checked 2026-10-11 against each vendor's own pages. Units differ: 2short.ai counts hours of analysis, OpusClip counts credits (1 per source minute), KeyMo counts source minutes.

Input options decide this comparison

2short.ai's homepage describes one way in: paste a YouTube video link into the app. The Lite plan and above add imports from Google Drive and public URLs. We found no mention of uploading a file from your computer on the pages we could read, and the app itself sits behind a login, so confirm that inside the account if local files matter to you.

There is a second condition. The 2short.ai FAQ says it can only process videos that have captions, and notes that YouTube generates captions for most videos. A raw MP4 straight off a recorder has no captions, so a link to it would have to point at somewhere those captions already exist. The privacy policy also describes generating shorts from public YouTube video links.

OpusClip is the most flexible of the three on intake. The free plan imports from YouTube and from local files. Starter adds Google Drive, Vimeo, Zoom, Rumble and StreamYard; Pro adds Twitch, Facebook, LinkedIn, X, Dropbox, Loom, Riverside and more. Links must be public or unlisted. One catch from its help centre: local uploads with non-integer frame rates are not supported, and the suggested workaround is to put the file on YouTube first.

KeyMo takes a YouTube link on paid plans or an uploaded MP4 or MOV, from 5 minutes up to 3 hours and 10 GB. The link import only fetches up to 1080p, and you confirm you own the video or have permission to use it. Those are the two ways in.

Worked example: a 90-minute interview saved as an MP4

Say you recorded a 90-minute interview and have it on your laptop as an MP4. What happens in each tool? This is arithmetic from the published rules, not a timed test.

Tool	Can the file go in?	What it uses up
2short.ai	The homepage describes YouTube links, plus Drive and public URLs on Lite. Local upload is not mentioned.	The free plan gives 30 minutes of analysis a month. The page does not say how analysis is counted. If it follows video length, a 90-minute video does not fit, and Lite's 5 hours would cover three such videos.
OpusClip	Yes, as a local upload (10 GB limit on Free and Starter, 30 GB on Pro per the pricing table).	1 credit per source minute, so 90 credits. Free has 60, so it cannot take the whole video. Starter's 150 covers one and leaves 60. Pro's 300 covers three.
KeyMo	Yes, as an MP4 upload, if the file is under 10 GB. At 90 minutes that is an average of about 15 Mbps or less.	90 of the 300 minutes on Starter, so three such videos a month. Pro's 900 covers ten.

The practical read: with only the file, 2short.ai means an extra step before you start, while OpusClip and KeyMo take it directly. If the interview is already a public YouTube video with captions, 2short.ai's path is just as short.

Clip rules and what you get back

OpusClip's default clip length is Auto, up to 3 minutes, and its Copilot setting lets you pick a length and a stretch of the video to clip. It gives each clip a virality score from 0 to 99, shown to Pro and Starter users only. Its help centre lists 23 to 32 clips as the range for a 30 to 60 minute video, so expect a long list to sort through.

2short.ai lists centre-stage face tracking, one-click animated subtitles, brand presets for logos and overlays, and advanced editing and cropping when automatic tracking misses. Its homepage does not say how many clips come back from a video or how long they are, so we leave those out.

KeyMo returns up to 15 clips per video in 9:16, each with a score out of 10 and a one-line reason. Only clips scoring 7 or higher are kept, which means a weak episode returns fewer clips instead of padded ones. Clip length choices are Auto (15 to 90 seconds), Short, Medium or Long. You can then open a clip and ask the chat editor for changes.

Where each one is stronger

2short.ai: a free plan, the lowest paid starting price at $9.90, and a features section that promises exports with no watermarks (it does not say for which plans). Lite costs $9.90 for 5 hours of analysis, against $12 for KeyMo Starter's 300 source minutes, though the two units may not be counted the same way.
2short.ai weak spots: the site is a single page with no terms, help centre or refund page we could find, the free-plan figure appears twice with different numbers, and the privacy policy we read is dated February 2023 and mentions GPT-3.
OpusClip: the widest list of import sources, a 10-hour input limit, scheduling to social accounts, team seats on Pro, limited API access on Pro, and 9:16, 1:1 and 16:9 outputs on Pro. It also has a real free plan, though with a watermark and a 3-day export window.
OpusClip weak spots: credits and minutes are used interchangeably across its own pages, the clean export needs a paid plan, and its Starter plan costs more than KeyMo Starter for half the processing allowance (150 credits against 300 minutes).
KeyMo: flat minutes, no watermark on any plan, 9:16 output at 1080x1920 only, and fewer but scored clips. It has no free plan, only two ways to add a video, and no output other than 9:16.

Which one should you pick?

Your video is a file on disk and you want to start now: OpusClip or KeyMo.
Your video is already public on YouTube with captions and you want to spend as little as possible: 2short.ai, starting on its free plan.
You want many candidate clips, a scheduler, many link sources or team seats: OpusClip Pro.
You want a short list of clips, each with a score and a reason, vertical only, with a clean export from the first paid month: KeyMo. See KeyMo pricing for the plans.
You only want to test the output quality: use the free plan of 2short.ai or OpusClip, and remember that OpusClip's free exports carry a watermark.
