Concatenate videos

We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos.

The /video/concat Robot concatenates several videos together.

What can I do with this?

Our /video/concat Robot can be used in combination with other Robots, to create powerful workflows unique to your use case. For inspiration, here are example scenarios, with explanations and code for all platforms, that you can also try live on our website:

Transloadit allows you to concatenate multiple videos together. This is useful when you want to add...
Let's say you want (your users) to insert video advertisements into existing videos at specific times....

This Robot supports parameters such as preset, ffmpeg, ffmpeg_stack to influence its behavior. Read all about the technical details in its docs.

Transloadit is a SaaS with a subscription model.

We offer a discount of 75%, effectively counting only every fourth byte of videos that you concatenate with /video/concat. Assuming an average input video of 80MB and an output of 48.0MB, here's what it would approximately cost to concatenate videos per Plan:

Plan Price Costs per file within your Plan Overage Fee
Sandbox (2GB) Free $0.0
to concatenate 21 videos
Startup (10GB) $49/month $0.459
to concatenate the first 106 videos
Small Business (30GB) $99/month $0.309
to concatenate the first 320 videos
Medium Business (150GB) $249/month $0.156
to concatenate the first 1600 videos
Enterprise 📞 - N/A

Just like with your mobile plan, pricing goes down when you commit to larger monthly volumes. When you reach your plan's limit, we'll continue to service you, but remind you to upgrade to more cost-efficient plans. This is unless you explicitly set budgets. You can change plans at any time. More info and available plans on our Pricing page.
