TikTok Shop accepts one product video per listing. Its Product Listing Policy caps that video at 5MB, while its Product Media Center page states 10MB and adds that the file must be MP4, shorter than 60 seconds, with an aspect ratio between 9:16 and 16:9. Both pages are TikTok’s own. Build to 5MB and you satisfy either. That cap, not the 60 seconds, decides how long your video can be.
Sellers meet this the hard way. They export a 60 second clip, watch the upload fail, drag the quality slider down until it passes, and ship a video that looks like a 2013 upload sitting next to nine sharp product photos.
There is a second constraint that matters more, and it is a content one. TikTok’s own guidance tells sellers not to build a product video out of still images. This guide covers both halves: the file specs with the arithmetic that follows from them, and what TikTok says the video should actually contain.
Key Takeaways
Two published caps, 5MB and 10MB. TikTok’s Product Listing Policy states sellers may upload up to 1 video per listing which must not exceed 5MB (seller-us.tiktok.com, accessed August 2026). Its Product Media Center page states a maximum size of 10MB (seller-us.tiktok.com, accessed August 2026). Build to 5MB. It is the stricter of the two and it satisfies both pages. This is the same pattern as TikTok’s pixel floor, which is published as both 600 x 600 and 800 x 800. One video per listing, MP4 only. Shorter than 60 seconds, aspect ratio between 9:16 and 16:9 (seller-us.tiktok.com, accessed August 2026). 5MB over 60 seconds is about 0.67 Mbps. That is unwatchable at vertical resolution, which is why long listing videos look broken. Six to ten seconds is the working range. At 8 seconds you get roughly 5 Mbps, which holds up at 1080 x 1920. TikTok tells you not to make a slideshow. Its guidance says do not use still, looping, or scrolling images through the entire video without featuring your face and the physical product (seller-us.tiktok.com, accessed August 2026). AI-generated voices are named in the LIVE rules. TikTok says not to use non-real-time verbal interaction such as AI-generated voices, audio recordings, or radio during LIVE (seller-us.tiktok.com, accessed August 2026).
What are the TikTok Shop product video requirements?
One video per listing, MP4 format only, shorter than 60 seconds, aspect ratio between 9:16 and 16:9, and a file size cap that depends on which TikTok page you read.
The Product Listing Policy, which is the policy document, says the video must not exceed 5MB. The Product Media Center help page, which is the upload tool documentation, says maximum 10MB. Both are current TikTok seller pages.
| Spec | Product Listing Policy | Product Media Center | Build to |
|---|---|---|---|
| Videos per listing | 1 | 1 | 1 |
| File size | Must not exceed 5MB | Maximum 10MB | 5MB |
| Format | Not stated | MP4 only | MP4 |
| Duration | Not stated | Shorter than 60 seconds | Under 60 seconds |
| Aspect ratio | Not stated | 9:16 to 16:9 | 9:16 |
This is not an unusual situation on TikTok Shop. The same policy publishes a 600 x 600 pixel floor for images while TikTok’s UK best-practice page publishes 800 x 800 for the same field. The rule that keeps you out of trouble is the same in both cases: build to whichever value is harder to hit.
The image half of the listing runs on its own spec set, covered in TikTok Shop product images and the square listing versus tall feed problem.
The file cap decides your video length
This is the part no spec sheet spells out, and it is pure arithmetic.
5MB is about 40 megabits. Divide by duration and you get the maximum average bitrate the file can carry:
| Duration | Max average bitrate at 5MB | What that looks like at 1080 x 1920 |
|---|---|---|
| 60 seconds | About 0.67 Mbps | Unusable. Blocking, smearing, banded gradients |
| 30 seconds | About 1.3 Mbps | Visibly degraded on any movement |
| 15 seconds | About 2.7 Mbps | Acceptable only for a static, slow shot |
| 10 seconds | About 4 Mbps | Workable on a simple product against a plain ground |
| 8 seconds | About 5 Mbps | Holds up, including moderate motion |
| 6 seconds | About 6.7 Mbps | Comfortable headroom for detail and texture |
Subtract roughly 128 kbps from each figure if the clip carries audio.
The conclusion is a production decision, not a technical one: build a 6 to 10 second product video, not a 60 second one. You give up nothing real. The listing video sits on a product card where a shopper is deciding whether to keep scrolling, and a tight loop of the product doing its one interesting thing beats a minute of b-roll compressed into mush.
The long version belongs somewhere else. Feed posts and paid ads run on different specs entirely, and how to create TikTok video ads with AI covers the ad build, including the dimensions and the AI disclosure toggle.
Getting a clean file under the cap
Work backwards from 5MB rather than exporting and hoping.
- Pick the duration first. Six to ten seconds. This single decision makes everything else possible.
- Keep 1080 x 1920. Do not drop to 720 to save file size. Shorten the clip instead. Resolution loss shows on a product; two fewer seconds does not.
- Set a target bitrate, not a quality slider. For 8 seconds, target 4.5 Mbps video and 96 kbps audio. That lands near 4.6MB with margin under the cap.
- Cut the fades. Fades are gradient frames, and gradients are expensive to encode. A one second fade at each end of an eight second clip spends a quarter of your file on frames nobody watches.
- Use a plain ground. Busy backgrounds and heavy grain eat bitrate. This is the rare case where the cheaper-looking set is also the technically correct one.
- Check the file, then check the frame. Under 5MB but the product edges shimmer? Cut two seconds and re-export. Do not lower the resolution.
Step 3 is where most sellers go wrong, because quality sliders are relative and file caps are absolute. Targeting a bitrate makes the output size predictable before you render.
What TikTok says the video should contain
The specs are the easy half. The content guidance is where AI-generated video gets sellers into trouble, and TikTok is unusually direct.
Its guidance on high-quality videos and LIVEs states three things that bear on this. Content should be dynamic, intriguing and appealing. Sellers should show their face, because that personal touch helps create a stronger connection with viewers. And sellers should not use still, looping, or scrolling images through the entire video without featuring their face and the physical product.
Read that last one twice. The default move when you have nine product photos and need a video is to pan across them with music over the top. TikTok names that exact pattern and tells you not to do it.
The LIVE rules go further: no stills, slideshows or scrolling images covering more than 50% of the screen, and no non-real-time verbal interaction such as AI-generated voices, audio recordings or radio. Those are written for LIVE sessions rather than listing videos, and they are worth knowing anyway because they tell you where the platform’s judgment sits.
So where does AI fit
Narrowly, and honestly. The objection sellers raise about AI content on TikTok is that it looks fake. On this platform that is not a matter of taste. It is a stated preference from the surface you are selling on.
The split that survives contact with the policy:
- Use AI for the product half. Clean packshots, alternate angles, styled scenes, and the motion shot that shows the product turning, opening or pouring. It starts from your real product photograph, so what is on screen is genuinely your product.
- Use yourself for the human half. Your hands, your face, your voice, unboxing it or wearing it. TikTok asks for this explicitly and no generated substitute reads better on a product card.
- Never build the whole video from stills. That is the specific pattern the guidance names.
This is a narrower use of AI than most tool marketing implies. Generating a shot of your product rotating on a seamless ground is production work. Generating a person who does not exist to hold a product they never held is where a seller ends up arguing with a policy team.
The same line runs through what makes UGC video quality hold up, and turning a product photo into a video ad covers the image-to-video step and the disclosure rules that come with it.
Building the clip from a photo you already have
Most TikTok Shop sellers have product photos and no video. Image to video is the shortest path, and it keeps the product accurate because the first frame is your own photograph.
A working sequence:
- Start from the best packshot you own. Sharp, well lit, product filling the frame.
- Generate one short motion clip from it. A slow rotation, a lid lifting, fabric moving. One action, not three.
- Hold it to 6 to 10 seconds. The file cap decides this, as above.
- Add one beat of real handling if you can. Even two seconds of your own hands changes how the clip reads.
- Export vertical at 1080 x 1920 and check the file size before upload.
DesignerBox runs this from the Video Studio, and the TikTok video generator is the free way to test whether the motion holds on your specific product before committing to a plan. For cutting and captioning, the video ad composer handles assembly.
Model choice matters more than it looks, because holding a product’s shape through a movement is the hard part. Seedance 2.0 is worth trying first on short product clips, and if you are weighing it against Kling, the side-by-side covers where each one holds up.
What video costs
Video is the most expensive operation in DesignerBox by a wide margin. Images are 5 credits each. Video is priced per second of output and the rate varies by model, so a short clip from a fast model and a short clip from a premium model are not close in cost.
Two things follow for a TikTok Shop seller. The 6 to 10 second discipline the file cap forces on you is also the cheapest way to work, which is a rare alignment of platform limit and budget. And you should check the per-second rate on the model page before queueing a catalogue, because the gap between models is the difference between covering every SKU and covering a handful.
Current rates sit on the individual model pages, and the 2026 AI creative cost benchmark puts per-asset figures against the alternatives. AI video needs Premium or higher, so it is not available on Basic or Pro. What DesignerBox does for TikTok Shop sellers covers the listing workflow rather than the plan.
Running video across a whole catalogue rather than one listing is a different budget question, and the economics of AI video at volume works through it.
FAQ
What are the TikTok Shop product video requirements?
One video per listing, MP4 only, shorter than 60 seconds, aspect ratio between 9:16 and 16:9. On file size TikTok publishes two figures: its Product Listing Policy says the video must not exceed 5MB, and its Product Media Center page says maximum 10MB. Build to 5MB and both are satisfied.
Is the TikTok Shop video limit 5MB or 10MB?
Both numbers appear on TikTok’s own seller pages. The Product Listing Policy, which is the policy document, states 5MB. The Product Media Center help page states 10MB. Treat 5MB as the working cap, because a file that clears the stricter page clears both.
Why does my TikTok Shop video keep failing to upload?
Almost always the file size. A 60 second clip at usable quality is several times the cap. Cut the duration to 6 to 10 seconds rather than lowering the resolution, and set an explicit target bitrate rather than using a quality slider.
How long should a TikTok Shop product video be?
Six to ten seconds. At the 5MB cap, a 60 second video can only carry about 0.67 Mbps, which is unusable at vertical resolution. A short clip at full quality beats a long one that had to be crushed to fit.
Can I use AI-generated video on TikTok Shop?
Yes, with a caveat that comes from TikTok itself. Its quality guidance says not to use still, looping or scrolling images through the entire video without featuring your face and the physical product, and it recommends showing your face. Generating product motion from your own product photo is fine. Building the whole video out of generated stills is the pattern the guidance names.
Does TikTok allow AI voiceovers?
TikTok names AI-generated voices in its LIVE rules, saying not to use non-real-time verbal interaction such as AI-generated voices, audio recordings or radio. That is written for LIVE sessions. Check the current policy before applying it to a listing video, because the two surfaces are documented separately.
What aspect ratio is best for a TikTok Shop product video?
9:16. The accepted range runs from 9:16 to 16:9, but the product card and the feed are both vertical surfaces, so a vertical clip uses the full space while a horizontal one is letterboxed into a strip.
