Best AI video object
replacement tools in 2026
Five tools that replace an object in a video, side by side: what each one does, what it costs to start and what you get free. Facts are sourced from each vendor's own page, with the date we read it.
For sellers and editors swapping objects in video
Your first 4-second swap is covered by your free credits. Then credit packs from $1.99.
What to compare before you pick one
The same four questions apply to every tool on this page.
What you give it
Some tools take a text description, some also take a photo of the replacement. A photo pins down the shape and colour of the new object.
How long a clip it handles
Limits differ: Luma Modify Video takes up to 10 seconds per upload, Vidio.ai lists a file size cap instead. Check the clip you actually have.
Subscription or per edit
Runway, Luma, Pika and Vidio.ai sell monthly plans. Inflyu sells credit packs you pay for per edit, with a monthly plan as an option.
What the free tier covers
Several tools keep object replacement behind a paid plan. Read the free-tier column before you upload anything.
How object swap works in Inflyu
Three steps, and you see the price before you spend a credit.
Upload your clip
Add a video you have the rights to. Pick the length you want edited: 4, 6, 8 or 15 seconds, or a whole clip up to 30 seconds.
Say what to replace
Name the object and describe its replacement, or add a photo of it. A photo is optional for an object swap.
Check the price, then run
On a clip of 4 seconds or more the edit runs shot by shot. The editor shows the credits before you run it, and a failed run is refunded.
Side by side
We make Inflyu, so it is first and marked. Every other fact comes from the vendor's own page, linked in the cell and dated 9 Oct 2026. Prices change, so confirm on the vendor page before you pay.

What an Inflyu swap costs, by clip length
Object swaps are priced per shot and length; the figure is the lowest, for one shot. Dollar amounts use the Power pack rate, the cheapest per credit. The editor shows the exact credits before you run.

Questions
What is an AI video object replacement tool?+
It swaps one thing in a video for another, for example a mug for a bottle, and keeps the rest of the clip as it was. You mark or name the object, then give a text description or a photo of the replacement.
Which tool is best for replacing an object in a video?+
It depends on what you have. Runway Aleph and Luma Modify Video sit inside larger video suites. Pika and Vidio.ai are lower-priced monthly options. Inflyu charges per edit and shows the price first. We make Inflyu, so check the linked vendor pages for the others.
How much does it cost to replace an object in a video with Inflyu?+
A shot-by-shot object swap starts at 12 credits for 4s, 17 credits for 6s, 22 credits for 8s, 40 credits for 15s. Clips with more shots cost more, and the editor shows the exact credits before you run. At the Power pack rate that is about $1.11 for the shortest clip.
Can I try Inflyu object swap for free?+
A new account gets 20 free credits once, no card required, and a free account can make one free video of up to 6s. Verify your email to see the price and run an edit. Free output carries a small Inflyu mark, and any credit pack removes it on new outputs.

No. Credit packs are one-time purchases that start at $1.99, and pack credits never expire. If you would rather refill each month, monthly plans exist too, and unused monthly credits do not roll over.
How current are the competitor prices on this page?+
Each competitor fact links to the vendor page it came from and shows the date it was read, most recently 9 Oct 2026. Plans and credits change often, so confirm on the vendor page before you pay. If a fact could not be confirmed on a vendor page, it is left out.
What does Inflyu not do well?+
Small print, fine logos and very detailed objects may not come out exactly, so check the result before you post. Use only clips you have the rights to.
