Runway Aleph Alternative: Edit Your Own Video (2026)

Runway's Aleph 2.0 is a video model that edits footage you already have. You describe a change, such as a new outfit, a different background or another product, and it renders the clip again with that change. It launched on May 21, 2026, inside Runway's Edit Studio. If you're looking for a Runway Aleph alternative, the right one depends on why: a clip longer than 30 seconds, a free first try, your phone, or the sound. This guide covers what Aleph 2.0 does well, the limits Runway publishes, the other tools that edit your own clip, and what our own tests with Riffkit's Swap mode kept and lost. Facts about other tools come from their own pages, as of November 2, 2026.

What Aleph 2.0 does well

It edits real footage, across shots. Runway's product page says Aleph 2.0 works on video you've filmed, not just AI-generated clips, and its launch post says it applies your edit across the relevant shots of a clip with cuts. The help center lists what it's built for: wardrobe, background swaps, relighting, weather, product and object swaps, character replacement, restyling and VFX. A Runway article from October 12, 2026 adds new camera angles.

You see the change before the video renders. In Edit Studio you pick a keyframe from your clip and edit it as a still first, with an image model (Nano Banana Pro at 20 credits an image, GPT Image 2 at 5, Gen-4 Image at 8). Aleph 2.0 then carries that edit through the video. You can add one reference image to steer a character, product or style, and when you edit only part of the clip, you pay only for that part.

It reaches past the web app. Aleph 2.0 is also in the Runway MCP (since July 14, 2026), Runway's Adobe plugins (September 8) and Runway's API as aleph2.

The limits Runway publishes

Runway's Edit Studio help article sets the rules for your clip:

• Length: longer than 2 seconds and shorter than 30. Longer videos are trimmed automatically.
• Cuts: up to 10. A video with 11 or more returns an error.
• Quality: 480p to 1080p (720p or 1080p recommended), 24 to 30 fps, conventional aspect ratios.
• Plans: Aleph 2.0 is on Runway's paid plans. The Free plan comes with 125 one-time credits and a limited set of models, and the help center says credit purchases aren't available on Free.
• Phone: Edit Studio is one of Runway's Apps, and the help center says Apps are currently unavailable in the iOS app but can be opened in a mobile browser. Runway also lists Aleph 2.0 in Runway Agent, which is in its iOS app; its pages don't say whether Aleph edits run there.
• Sound: Runway's pages don't say whether the standard MP4 keeps your clip's audio. Its ProRes export (Max, Enterprise and legacy Unlimited plans) comes with uncompressed PCM audio, but only for edits of the full clip, at 5 extra credits a second; an edit of part of a clip always comes back as an MP4.

Cost. Aleph 2.0 bills 28 credits a second, with a 56-credit minimum. Runway's Standard plan is $15 a month, or $12 a month billed yearly, with 625 credits a month; its pricing page counts that as 53 five-second Aleph 2.0 videos a year. Pro ($35, or $28 yearly) comes with 2,250 credits and Max ($95, or $76 yearly) with 9,500.

Other tools that edit your own clip

Sound is where they differ most. Luma says Modify Video keeps your original audio. Kling's 3.0 Omni guide marks native audio as not supported yet when a video is the input, and its 4.0 guide doesn't say whether a video's original audio is kept, though one of its example prompts asks to keep it. Riffkit's Swap keeps the source's sound wherever no voice changes.

Plans differ too. Kling's blog says its 3.0 models open to Pro, Premier and Ultra members, and Luma's pricing page starts with a paid plan, Plus at $30 a month. Riffkit can be tried free (details below).

PixVerse and Pika also edit uploaded clips, but we couldn't confirm their current limits on their own pages, so they're left out of the table. For the character-swap side of this (Genjutsu, Magic Hour, Scenario), see our Higgsfield Genjutsu alternative guide.

Riffkit Swap: the same kind of edit, up to 45 seconds

Swap is the Riffkit mode for changing what's in a video you already have. You write what to change and Swap renders the clip again: the shots, cuts, camera moves, timing and framing follow the source, and so does the sound wherever no voice changes. With no character picked, the person in the clip stays.

1. Add the clip. Upload a file of up to 100 MB and 45 seconds, paste a link to your own TikTok post or pick a template. A longer or bigger file is turned down, not cut, so trim it first.
2. Write the change in "What to change". When it differs from shot to shot, name each shot. To show it with a photo (an outfit, your pet, your car), add the photo on the References page and pick it under "Reference images".
3. Pick an engine. Free accounts can Swap on Seedance 2.0 Fast or Seedance 2.0 at 480p; a plan adds 720p and 1080p, Seedance 2.5 and MiniMax H3.
4. Check the price and submit. The form shows the billed seconds and the credit total before you tap Riff it →.

On a phone. Riffkit runs in Safari on an iPhone, with nothing to install: tap Upload or paste a link, pick the clip from Photos and keep the page open until the upload finishes. iPhone video at 4K and 60 fps fills 100 MB in about 15 seconds, so trim it or record at 1080p and 30 fps, where 45 seconds fits. On Android there's a Riffkit app on Google Play. In Claude or ChatGPT with the Riffkit connector, ask the assistant for an upload link; making videos in ChatGPT and Claude has the setup.

Voices depend on the engine. On Seedance 2.0 and 2.0 Fast, the original voice stays. On Seedance 2.5 and MiniMax H3, a person you replace gets a new voice for their lines on camera, unless you write "keep the original audio".

What our tests kept, and what drifted

We have run Swap on six kinds of change, all on clips we made with AI (the pet and car photos too), and written each one up shot by shot against the original. The cuts held in every test: where we timed them (the cat, car, background and hair tests and the first day-to-night run), they landed within one frame of the original's, and where we compared the sound sample by sample, it was the original's.

The pattern: in the five tests on shorter clips (three or four shots or scenes), the change reached every one in three, and the other two each missed one shot. On the 12-shot clip it reached half the shots at best. Every source was a clip we made with AI, standing in for yours (the hair and background tests share one); we haven't published a test on real phone footage yet, or on a clip near the 45-second cap. So check every shot before you post. If your clip has up to 10 cuts and every shot needs the same change, Runway says that is what Aleph 2.0 is built for: it carries one edit across the shots.

Aleph 2.0 or Riffkit Swap at a glance

Which should you pick?

• Your clip has up to 10 cuts and one change must land in each: Aleph 2.0, which Runway says carries one edit across the shots (we haven't tested it).
• Your clip runs 30 to 45 seconds: Riffkit Swap takes it as one job and, on a plan, returns it at full length. Our published tests used clips of 13 seconds or less, so check every shot of a longer one.
• You want to try before you pay: Riffkit, on the free 480p engines (a clip under 8 seconds comes back whole; a longer one, as its first section).
• You need your original audio, stated in writing: Luma's Modify Video says it keeps it, for up to 20 seconds; Swap keeps the source's sound wherever no voice changes.
• You want many reference images: Higgsfield Genjutsu takes up to 30.
• You're on your phone: Riffkit in Safari or the Android app, or Runway's Edit Studio in a mobile browser.

What it costs, and how to start free

Swap bills per second of finished video, at its own rates:

Runway credits and Riffkit credits are different units, so the per-second numbers don't compare directly. Each render bills whole seconds, rounded up, with a 4-second minimum, and failed renders aren't charged. Plans start at $15 a month for 3,000 credits, or $12 a month billed yearly.

New accounts start with free credits, no card needed, and can Swap on Seedance 2.0 Fast 480p or Seedance 2.0 480p. A clip under 8 seconds comes back whole; a longer one usually comes back as its first section, and a plan renders the rest from the same script. Until the account pays, its videos carry a small Riffkit watermark, and any plan removes it from every video, earlier ones included.

Use footage you own

Swap keeps everything you don't change, so start from a clip you made or have the rights to. Keeping another creator's person, voice or music doesn't make their video yours to post. When a video on someone else's account is the one that worked, Riffkit's Adapt mode keeps its beats and makes new footage with your own story.

Try it on your own clip

Open Swap, add a clip of up to 45 seconds and write one change in "What to change". The price shows before you submit, and a free account can try it at 480p with no card.
