I’ve got a multiple sets of videos I want to stitch together. Is this possible using you?
Hi Jack,
Yes. Stitching together a range of videos using the API is very easy to do. In the following example I’ll stitch together a range of videos. You can also use transitions between clips.

Stitching videos with unknown durations
Often you do not know the exact length of the video. For this you can use the Media Inspector API endpoint. This endpoint provides you with detailed metadata of your video. Just make sure to encode your the URL you’re looking to probe like this:
Original url
https://shotstack-assets.s3-ap-southeast-2.amazonaws.com/footage/table-mountain.mp4
Encoded url
https%3A%2F%2Fshotstack-assets.s3-ap-southeast-2.amazonaws.com%2Ffootage%2Ftable-mountain.mp4
curl -X GET https://api.shotstack.io/edit/{version}/probe/{video_url} \
-H 'Accept: application/json' \
-H 'x-api-key: API_KEY'

Stitching Videos Using Integromat or Zapier
You can also stitch together your videos using an automation platform like Zapier or Integromat. Here the duration of your videos is calculated for you. Easy.

I may be missing something, but I don’t see an option in Integromat for the “Stitch” Shotstack module. I see it says “(version 2)” on your screenshot, is this something that hasn’t come out yet? The only module options I have are Render, Watch, and Make an API Call. I’ve been struggling to figure out how to stitch videos together on Integromat for a while, and finally figured it out using an Array between Google Sheets and Shotstack. But that stitching module seems like a better way, except that I can’t find it. Am I missing something?
Yeah I shared that a bit too enthusiastically. The new Integromat modules are currently under review and should be publicly available soon.
You can get early access to these new modules using the following link: Developer Platform | Integromat
