This chapter explains how video rendering works and how to start creating CPVs.
What is CPV rendering
Rendering is the process of:
Creating video files from your selected Template Set
Uploading them automatically to the correct Meta catalog
Making them available for ad delivery
There is no manual export or upload required. Once you apply a Template Set, Creative Factory handles everything automatically.
How video creation works
With the transition to Creative Factory, the way CPV videos are created has been updated:
CPVs rendered BEFORE the migration to Creative Factory will automatically use by default Pre-Render option (see the details HERE)
CPVs created AFTER the migration to Creative Factory follow the new default rendering described below:
New video creation flow
Previously, videos needed to be rendered in advance before campaigns could fully deliver. In Creative Factory, videos are now created as campaigns begin delivering. This means campaigns can start immediately, while video creation happens in the background and expands over time based on delivery performance.
How it works
Rendering starts after you click Apply Changes, which activates video creation for the selected ads.
Meta decides which products receive videos from the connected catalog.
You don’t manually select products - video creation is fully automated.
Videos are created only when Meta requests them, not for the entire catalog at once.
Videos are typically available within 24 hours, with coverage expanding over time.
No manual exports or uploads are required, as Creative Factory handles the process automatically.
Benefits
✅ No daily rendering limits.
✅ No catalog size restrictions.
✅ No waiting for full segment rendering.
✅ Videos are created automatically when Meta requests them.
This allows you to scale CPVs across entire catalogs, multiple markets and multiple campaigns instanty.
Best for:
Full catalog promotion
Multi-market expansion
Ongoing performance campaigns
Fast launches without operational delays
How to create videos for a selected segment only (Segmented Creative)
By default, Meta selects products from your entire catalog for video creation. If you want to limit video rendering to a specific segment, you can enable Segmented Creative and choose a segment. The rest of your catalog will continue serving with images.
This allows you to align specific creative messaging with a selected product group
(e.g. New Arrivals segment paired with a custom “New Collection” video template).
Best for:
When you have a creative highlighting a specific product segment:
Product categories
Items on sale
Bestselling items
How It Works
Enable Segmented Creative
Select a product segment (e.g. New Arrivals)
❗️Note: Segmented Creative can only be enabled for new Template Sets. ❗️
From that moment:
Only products within the selected segment are eligible for video creation
Meta still decides which products inside the segment receive videos
The rest of the catalog continues serving with images
⚠️ Important: Segment is locked to the Template Set ⚠️
When you enable Segmented Creative and choose a segment, the selected segment becomes part of that Template Set.
This means:
If you reuse the same Template Set later, it will always render videos only for that segment
The segment cannot be edited or replaced
If you need to use a different segment, create a new Template Set.
Pre-Render option
With the transition to Creative Factory, the way CPV videos are created has been updated:
CPVs rendered BEFORE the migration to Creative Factory will automatically use by default Pre-Render option described below
CPVs created AFTER the migration to Creative Factory follow the new default rendering (see the details HERE)
When using Segmented Creative, Meta selects only products from within your chosen segment. In some cases, Meta may select only a small number of products from that segment.
If this happens, the system may offer you the option to create videos for all products in the segment. This option appears in the Videos Dashboard when low overlap between Meta’s selection and your segment is detected.
How this option works
Videos are created for all products in the selected segment.
Meta does not control selection.
Rendering happens gradually.
❗️Limit❗️
Maximum 500 videos per day across all catalogs.
Large segments may take multiple days.
Example: If your segment has 1,000 products, rendering will take approximately 2 days.
Used for:
Small specific segments of products or when Meta doesn’t promote the products yet
Small capsule collections
New Arrivals
Hidden gems and hero products
⚠️ When Pre-Render Is Used by Default ⚠️
If your templates contain dynamic data Pre-Render is selected by default and On-Demand rendering is not available.
This happens when your template contains dynamic fields such as:
Price
Frequently updated custom fields
Why?
Frequent data changes require videos to stay consistent with the latest values.
To prevent inconsistencies (for example outdated prices), the system creates videos for all products in the selected segment.
Be aware!
Frequent price updates can trigger repeated re-rendering.
Possible solutions:
Reduce frequency of price updates
Remove price from template if constant updating is unnecessary
Troubleshooting rendering issues
Some products don’t have videos
Possible reasons:
Meta hasn’t requested them yet
If you're using Segmented Creative, product not in selected segment
Rendering is still in progress
Segment overlap with Meta selection is low
✅ Solution:
Consider enabling Pre-Render if guaranteed coverage is required.
Rendering takes too long
Possible reasons:
Large segment with Pre-Render option enabled
Daily 500-video limit was reached
Frequent feed updates triggering re-renders
✅ Solution:
Reduce segment size
Prioritize high-impact products
Check dynamic fields in template
Videos don’t appear in ads
Check:
Was Apply Changes confirmed?
Is Dynamic Media enabled at ad level?
Has rendering finished?
Is the correct catalog selected?
Glossary
Template Set:
A group of up to three video templates (one per aspect ratio) that can be applied and reused across multiple ads.
Aspect Ratio:
The proportional relationship between a video’s width and height, such as 1:1 (square), 4:5 (vertical), or 9:16 (story format).
Segment:
A subset of products in your catalog, such as “New Arrivals” or “Top Sellers,”.
Segmented Creative:
An option that lets you apply video templates to specific product segments instead of the whole catalog.
Pre-Render:
A mode where videos are proactively rendered for all products in a segment, not just those selected by Meta. Subject to the 500 videos/day limit.
Dynamic Media:
A Meta Ads feature that automatically mixes images and videos for each product, optimizing creative delivery based on user behavior.
Catalog Product Videos (CPVs):
Short video creatives assigned to individual products in your Meta product catalog.
