How can I create a slideshow ad in Ads Manager?
Creating a slideshow ad for Facebook and Instagram from multiple images or a video by using ad creation is easy.
- First, choose your objective. Slideshow is available for all objectives except Product catalog sales and Post engagement.To run your slideshow ad on Instagram too, choose Traffic, Conversions, App installs or Video views.
- Add your targeting, budget and scheduling information. Click Continue.
- In the Format section, click Slideshow.
- Click the Create Slideshow button below.
- In the popup, upload 3–10 images or a video asset to transform into a slideshow.
- Set an Image Duration for your ad of up to 50 seconds.
- Set the Transition to Fade, if you choose.
- Click Music at the top to upload music for a slideshow (supported formats: WAV, MP3, M4A, FLAC and OGG). You must have all legal rights necessary to use the song. Usually this means you licensed the song for use with your slideshow, or own the rights to it. If you only bought or downloaded a song or album, that generally means you can't use it in a slideshow. Learn more about copyright here. If you don't have an audio track, there is a range of music to choose from in the Slideshow tool.
- Click
on each of your photos if you'd like to add text. An Edit Photo popup will appear where you can enter a caption, choosing the font, size and positioning. Click Save. 
- Click Create Slideshow to build your video. Your slideshow will be ready to review in less than 2 minutes.
- Choose the thumbnail for your slideshow ad. This is the image you choose to show before the video starts and when it is finished. This has a big impact on how people respond to your ad.
- You can choose to add Video Captions; a good option for people watching with sound off.
- Choose the Page you'll be promoting.
- Finally, enter the text and links you want to show in the ad and any call to action buttons that may be available.
- Use high-quality images and avoid grainy images.
- Use images that are all the same dimensions, ideally 1280 x 720 pixels or an image ratio of 16:9, 1:1 or 2:3. If you use images of different sizes, your slideshow will be cropped to be square.
- For video uploads, choose .MOV or .MP4 file types.
