# Step 4 - Creatives (New)
## This page allows you to review creative specifications, upload and manage creatives in your line items.
### What is Step 4 - Creatives?
Step 4 is where you add the creatives of your Line Item and decide on which screens they play. From this step, you can:
- **Check the specs** expected by the screens of your targeting and deals
- **Upload creatives** from your computer, your campaign library, a VAST Tag or a DCO package
- **Manage your creatives**: activate, pause, rename, download or delete them
- **Assign your creatives** automatically by resolution, or by city, region, country, media owner or screen, one by one or in bulk with an Excel file
**⚠️ Important: Save your changes**
Changes in Step 4 are **not saved automatically**. After adding or assigning creatives, click **Save** on your Line Item. Otherwise, your changes will be lost.
### How to use it?
Open your Line Item and go to **Step 4 - Creatives**. Then:
1. **Check the creative specifications** to see what your screens expect.
2. **Upload your creatives.** They are automatically optimized and assigned to the screens that fit their format.
3. **Manage your creatives**: pause, rename, download or delete them.
4. **Check your coverage** and add creatives for the specs not covered yet.
5. **Choose where each creative plays** (optional): by resolution, or by city, region, country, media owner or screen
6. **Save your Line Item.**

### 1. Check the creative specifications
Start here. Click **View specs** to see what the screens of your Line Item accept, so you can prepare creatives that match. Specs are based on your targeting (Step 2) and the deals selected in Step 3.
| Column | What it tells you |
| --- | --- |
| Ratio / Resolution | The dimension your creative must have |
| File type | Accepted formats (image, video, VAST Tag, HTML…) |
| Duration | Min and max length for videos |
| Frame rate / Max size | Technical limits of the screens |
| Forecasted imp. | Estimated impressions on these screens, based on your deals |
| Screens | Number of screens with this spec |
- **Combine forecasted impressions with the number of screens** to choose the most relevant formats for your campaign. The list is sorted by forecasted impressions: start with the top rows.
- **Each row is a distinct spec.** Two rows can share the same resolution but differ in duration or file size: they usually come from different deals or publishers. To maximize your reach, **cover as many rows as possible**.
- Use the search bar to find a resolution or format quickly.
- Click **Export CSV** to share the specs with your agency or creative team.
- If you change your targeting or your deals, check the specs again.
Forecasted impressions are indicators of how many formats the SSPs require. Displayce cannot guarantee 100% of this reach: factors such as SSP data accuracy or screen availability can affect real-time bidding results.
### 2. Upload your creatives
**When your Line Item has no creative yet, Step 4 shows an upload area with 4 options:**
- **Browse files**: pick files from your computer, or drag and drop them into the area.
- **Select from library**: reuse creatives already uploaded on other Line Items of the same campaign. Search by name, tick one or several, then click **Add**. Creatives already in your Line Item are not listed.
- **VAST Tag**: paste the tag URL, check the preview, then confirm. This option is only available if your Line Item uses Ströer and/or SSP1 deals.
- **DCO package**: pick the resolution. Only the resolutions of your targeted screens are listed.
**After the upload, the platform automatically:**
1. **Optimizes** your files to meet the screens' requirements (frame rate, file size, resolution, duration). This can create one or more adapted copies of your creative, called **variants**. VAST Tags and DCO packages are not optimized.
2. **Assigns** each creative to every targeted screen that accepts its resolution.
**⚠️ Don't forget to save.** Click **Save** on your Line Item once your creatives are added.
### 3. Manage your creatives
**Once you've added a creative, a table lists all your creatives. At the top:**
- 2 gauges show your **estimated screen and impression coverage**. They update as soon as you add, remove or pause a creative.
- **View specs (X/Y covered)** tells you how many screen requirements your creatives cover.
- **Add creatives** lets you add more.
- **Assign by** shows how creatives are assigned to screens (*Resolution* by default).
| Column | What it tells you |
| --- | --- |
| Active | Turn the creative on or off |
| Preview | Click to see it bigger |
| File name | Name of your creative |
| Covers | How many screen requirements it covers. **Red means it fits no screen** |
| Forecast imp. / Screens | Its expected share of impressions and screens |
| … | Rename, see specifications, download or delete  |
- **Pausing** a creative stops its diffusion: Displayce's real-time bidder no longer uses it for media buying. A paused creative is greyed out and no longer counts in the gauges.
- Click the **Covers** badge of a creative to see which specs it matches.
Creatives in *Planned*, *Running*, *Blocked* or *Finished* Line Items cannot be deleted. A creative you've just added can still be deleted until you save the Line Item.
**Optimized creatives and Detailed view**
When the platform optimizes a creative, it creates adapted copies called **variants**. By default, the table groups the original and its variants on a single row:
- The name shows without a file extension, because the row can hold several files.
- Actions (pause, delete, rename) apply to the whole group.
- *1 out of 2* in the Active column means only some files of the group are active.
To see each file separately, turn on **Detailed view**. Each file then gets its own row, with its full name (extension included), resolution, duration, frame rate, weight, the optimizations applied and the publishers.
### 4. Check your coverage
Once your creatives are uploaded, open **View specs (X/Y covered)** again and click **Not covered**.
You get the list of specs no creative matches yet: **these screens won't show your creatives.** Upload a creative in each missing format to cover them.
- Start with the specs at the top: they carry the most impressions.
- Click **Export CSV** to send the missing specs to your creative team.
- The **Coverage** column shows how many creatives cover each spec. Hover to see their names.
### 5. Choose where each creative plays
In **Assign by**, choose the assignment type that best suits your campaign:
- **Resolution** (default): each creative goes to every screen that can play it. You don't need to do anything.
- **City**: to show a specific ad in a particular city.
- **Region**: to show a specific ad in a particular region of a country (e.g. Flemish Region in Belgium).
- **Country**: for multi-country Line Items where different ads are needed.
- **Media owner**: to show a specific ad on a given media owner's screens.
You can use only **one** assignment type at a time on a Line Item.
⚠️ **In City, Region, Country, Media owner or Screen mode, no creative is assigned by default.** You have to assign each creative yourself. As long as a creative isn't assigned, it doesn't deliver.
1. In **Assign by**, choose **City**, **Region**, **Country**, **Media owner or Screen**.
2. Confirm in the window that opens. Switching mode removes all current assignments.
3. On each creative, click the red badge (e.g. **City required**).
4. A side panel opens with your targeted cities. Tick the ones you want, then apply.
5. Click **Save** on your Line Item.
In the side panel:
- Only the cities where the creative can play are listed.
- For each city, you see the share of impressions your creative can actually get. For example, if most screens in Bordeaux are landscape and your creative is portrait, it will only cover a small part of Bordeaux.
To go back to automatic assignment, choose **Resolution** in **Assign by**, then click **Save**.
#### Assign in bulk with an Excel file
Useful when your Line Item targets many cities, regions, countries or media owners. In City, Region, Country, Media owner or Screen mode, click **Bulk assign** at the top of the table.
1. **Download the template.** It already lists all your targeted cities. Next to each city, write the file name of the creative to use. To use several creatives in the same city, copy the city row.
2. **Upload your file.** Already have one ready? Click **I already have a XLSX** to skip step 1.
3. **Review and apply.** Valid and invalid rows are listed. Click **Apply \[N\] assignments** to apply the valid ones.
4. Click **Save** on your Line Item.
- Invalid rows are skipped. Fix your file and upload it again, or finish manually in the side panel.
- A new import replaces all your previous assignments. Your file must include every assignment you want to keep.
- The file check doesn't look at formats. If you pair a city with a creative its screens can't play, the row shows as valid but nothing is assigned there. Check **View specs** before filling in the file.
- Avoid creative names made only of numbers (e.g. *280 420*): Excel may change them and return *File not found*.
| Error message | What to do |
| --- | --- |
| Could not import creative | The file format is not supported or the file is too heavy. Check **View specs** |
| Need creative | Add a creative file name in the row |
| File not found | Check the name: it must exactly match a creative of the Line Item |
| Not in targeting | This city is not in your targeting. Remove the row |

### FAQ
**My creatives or assignments disappeared after I left the page.**
→ Your Line Item wasn't saved. Click **Save** after any change in Step 4.
**My creative shows "0 specs" in red. Why?**
→ None of your targeted screens accepts its format. Open **View specs** to see the expected formats.
**I switched to City and my forecast dropped to 0%. Is that normal?**
→ Yes — in City, Region, Country, Media owner or Screen mode, no creative is assigned by default. Assign each creative from its red badge or with **Bulk assign**, then save.
**Why don't I reach 100% of the forecasted impressions?**
→ Forecasts are estimates. SSP data accuracy, screen availability and real-time bidding can all affect actual delivery.
**I can't find the Bulk assign button.**
→ You're in Resolution mode. Switch **Assign by** to City, Region, Country, Media owner or Screen.
**Can I reuse a creative from another campaign?**
→ No — the library only shows creatives from the same campaign.
**Can I assign creatives by point of interest?**
→ No — this assignment type is not available at the moment.
