The thing to understand first#
Dynamic Media is on by default for catalog ads. Meta may already be showing videos on your
catalog ads today, whether or not you supplied any — because where a product has no video, Meta may
go and find one.
That's the real reason to do this, and it's covered in its own section below.
Before you start#
- A Meta channel with adaptive designs turned on and at least one
design group — see Set up design groups.
- A Studio template that renders video. Animated templates are built the same way static ones
are; see Animated product videos for the template side and
Video templates for what they can do.
- Every product still needs an image. Meta requires it — "Every product also needs an image,
even if you plan to use only product videos" — so video designs are added beside your image
designs, never instead of them.
Rendering video is the most credit-intensive thing on the platform, since every product needs a full
render. Start with a small product set while you're iterating. See
What uses my credits.
1. Add a video design to a group#
On the channel's Fields tab, open Adaptive designs.
Every group in the grid is two rows — its image designs, then its video designs — and the video row
stays collapsed to a single Add video link until the group has its first video design. Once it
opens, a video design is easy to pick out: its tile carries a play badge and its caption ends with
how long the video runs.
- On a group that already exists, click Add video on that group's row and pick a template
size. The video row opens as a row of cells, and from then on you add a video per shape by
clicking an empty cell in it — exactly as you do for images.
- When you add a new group, click the dashed Add a design group row beneath the grid — the
dialog switches to the add-group view. The form asks for an image template and an optional video
template. Filling both in creates one image design and one video design per template size, all in
the same group, so the new group arrives with its video row already open.
Image and video designs in a group are two facets of one creative concept, not two things to choose
between. You pin the group; Meta picks the medium.
Afterwards, any single video design can be pointed at a different video template on its own:
hover its cell and click the pencil. The picker offers only templates that can render video, in the
shape of the column you clicked, and the design keeps its name — see
Set up design groups.
2. Video needs no shape markers#
Your feed's default designs carry Meta's reserved shape markers — that's what lets Meta match one
to a surface with no pinning — and groups you add afterwards deliberately carry none. A video
design needs neither, which is correct rather than an omission: a video's shape is intrinsic to the
file. In Meta's words, "if a video matches the aspect ratio for the ad placement, that video is
returned."
The same goes for the Instagram, Stories and Reels marks on the default image designs:
Meta documents those for images and defines no video equivalent, so a video design's picker doesn't
offer them at all.
Meta doesn't say how it determines that match, so Renable doesn't either. What you can do about it is
straightforward: supply the ratios you care about — a video design per size your video template
carries — and let Meta match them.
What that means in practice is that a video's shape lives in the file, not in a marker Renable
writes. Renable still places each video design in the shape column its bound size resolves to — a
1080 × 1920 video design sits in the Story column exactly as a 1080 × 1920 image design does — so a
group's video coverage reads the same way its image coverage does, and its picker offers only sizes
of the column you clicked. What Renable does not do is tell Meta which shape a video is; Meta reads
that from the video itself.
3. Publish, and give Meta time to fetch#
Press Publish on the channel. Until Meta fetches the updated feed, the video designs aren't in
Meta's copy of your catalog. The Renable Options panel's freshness line tells you when Meta last
fetched.
One thing to expect and not worry about: the panel never warns that Meta is missing a video
design. Meta fetches catalog video lazily and may not fetch it until the product is in an active
campaign, so "not in the sample" and "not fetched yet" look identical from outside — and a warning
that fires on every healthy new video design is a warning people learn to ignore.
4. Pin an ad to the group#
Open the ad in Meta Ads Manager with the
Renable Options extension installed, find the group, and click
Use. The panel shows a group's image and video designs together, because they travel together.
Renable turns Dynamic Media on for the new version when it can pin the group's video by name.
That switch is what lets a catalog video serve at all, so pinning a video-carrying group without it
would suppress the very thing you pinned. For an image-only pin Renable does the opposite and turns
Dynamic Media off, so Meta shows exactly the design you chose.
The confirmation tells you exactly what it set — worth reading rather than assuming, because the
direction follows what Renable was actually able to pin, not simply whether the group has video
designs in it.
After that, the panel changes what it says about Dynamic Media on this ad. On an image pin, Dynamic
Media being on is a warning — Meta may substitute something for your design. On a video-carrying
group pin it's the mechanism doing the work, so the panel notes that it's what lets the video show —
and warns you if it has been switched off, because then the video can never surface.
The videos Meta adds by itself#
This is the part most people don't know about.
Meta automatically adds product videos to catalogs, and the setting is on by default. Where a
product has no video, Meta may scan your public product pages, videos you've uploaded to Ads Manager,
Reels and videos on your Facebook Page or Instagram profile, other products in the same catalog, and
your other catalogs — and add what it finds. There's no approval step; auto-added videos appear
immediately.
Those are videos you didn't make, didn't brief, and don't control, running beside creative you did.
The fix is structural, and it's the point of this article. In Meta's own words: "If you add a
video to a product yourself, it takes priority over all automatically added videos, which makes them
disappear from the catalog." A video-carrying design group supplies your video for every product it
renders, which evicts the scraped ones per product. Your remaining exposure is only products your
feed gives no video to.
If you'd rather switch the behaviour off entirely, the setting lives in Meta's Commerce Manager under
the catalog's settings, as Automatic product video updates — turning it off removes auto-added
videos within about a day. You can also reject them, but rejection is per product and
all-or-nothing: you can't reject one of several auto-added videos on the same product, and
rejecting permanently stops auto-adds for that product. Meta moves Commerce Manager's settings from
time to time, so if you can't find the switch, Meta's own guide to
automatically added product videos has
the current location.
If your channel already sends a plain video column#
Some channels carry a plain product-video field from before adaptive designs. Renable leaves it
alone: the Adaptive designs dialog acknowledges it, it stays your ads' default video, and video
designs are added beside it. Nothing is converted, and nothing is removed.
What Meta's own limits are#
Two facts worth having, both from Meta's documentation, because both get misquoted:
- There is no length limit on a catalog video. The "keep it to 15–20 seconds" figure that
circulates is a vendor recommendation, not a Meta rule.
- Meta asks for at least 500 × 500 pixels, and caps a feed-supplied video file at 200 MB.
What we never promise#
Renable writes the video designs into your feed and writes the pin onto the ad's creative. Everything
after that is Meta's, and the copy in the product stays on the right side of that line:
- Meta decides when and where a video shows. Renable never claims a particular medium will run on
a particular surface, and never says what renders for a product that has no video — Meta doesn't
document it.
- Dynamic Media is a switch, not an outcome. Turning it on is what makes a catalog video able
to serve; it isn't a promise that one will.
- Adapt to placement governs image shape adaptation: it has to be switched on in the ad's
Advantage+ settings for Meta to match one of a group's image designs to the surface — in our
testing, with it off the ad showed one image design everywhere. A video's shape works the other way
round, from the file itself, so this setting isn't what steers video. Renable switches it on for an
ad you pin from the extension, and warns you when an ad has it explicitly turned off.
Turning it off#
Removing the videos one at a time is the way back: hover a cell in the group's video row,
click the pencil, and use Remove design at the bottom of the picker. That takes just that video
out of the feed on the next publish, leaving the group's image designs — and everything else —
untouched, so ads pinned to the group keep their images. Beyond that, delete the group to remove
the whole concept, or turn off adaptive designs to leave the feature entirely. In every case the
video designs are removed rather than converted, because there's no plain field for them to
become.
The confirmations differ in how much they tell you. Remove design names the one design it is
about to remove, and turning the feature off lists every video design it will remove, by name,
before anything happens. Deleting a group warns you that its designs leave the feed on the next
publish and that ads pinned to it fall back to your default designs — without naming them
individually, so read the group's row first if you want to know exactly what's going. See
Run different designs for different campaigns or seasons
for why deleting a group is usually the wrong move when un-pinning would do.
