Crop a video to fit a LinkedIn feed post
🤖/video/encode allows you to easily manipulate video files. In this demo, it resizes an uploaded video file, converting it to perfectly match the size needed for uploading to your LinkedIn feed and then applies a watermark.
In this demo we have manually set the converted dimension sizes, using the height and width
parameters paired with the fillcrop
resize strategy, however there are many other
parameters you can check out for 🤖/video/encode.
To add a watermark to your uploaded video, simply set the URL of your desired watermark with the
watermark_url parameter or you could also change your Assembly Instructions so that it
can take one of the uploaded files as the watermark</a
.
To fine-tune how your watermark will be displayed, you can use additional parameters such as
watermark_size and watermark_position.
To find the current dimensions of a LinkedIn feed video we used our own Peter Assentorp's excellent socialsizes.io. Make sure to check it out for other useful dimensions for your social media accounts!
Step 1:
Handle uploads
We can handle uploads of your users directly.Learn more
":original": {
"robot": "/upload/handle"
}This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically
Step 2:
Transcode, resize, or watermark videos
We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos.Learn more
"resized": {
"use": ":original",
"robot": "/video/encode",
"result": true,
"ffmpeg_stack": "v7",
"height": 1200,
"preset": "ipad-high",
"resize_strategy": "fillcrop",
"width": 1200
}This bot encodes, resizes, applies watermarks to videos and animated GIFs
Step 3:
Transcode, resize, or watermark videos
We offer a variety of video encoding features like optimizing for different devices, merging, injecting ads, changing audio tracks, or adding company logos.Learn more
"watermarked": {
"use": "resized",
"robot": "/video/encode",
"result": true,
"ffmpeg_stack": "v7",
"preset": "ipad-high",
"watermark_opacity": 0.7,
"watermark_position": "top-right",
"watermark_size": "25%",
"watermark_url": "https://demos.transloadit.com/inputs/transloadit-padded.png"
}This bot encodes, resizes, applies watermarks to videos and animated GIFs
Step 4:
Export files to Amazon S3
We export to the storage platform of your choice.Learn more
"exported": {
"use": [
"resized",
"watermarked",
":original"
],
"robot": "/s3/store",
"credentials": "demo_s3_credentials",
"url_prefix": "https://demos.transloadit.com/"
}This bot exports encoding results to Amazon S3

Loading Uppy demo…
This live demo is powered by 
Uppy, our open source file uploader that you can also use without Transloadit, and 
tus, our open protocol for resumable file uploads that is making uploading more reliable across the world.
Build this in your own language
<!-- This pulls Uppy from our CDN -->
<!-- For smaller self-hosted bundles, install Uppy and plugins manually: -->
<!-- npm i --save @uppy/core @uppy/dashboard @uppy/remote-sources @uppy/transloadit ... -->

So many ways to integrate
Transloadit is a service for companies with developers. And there are many ways developers can put Transloadit to good use inside your company to automate media processing.
Bulk imports
Add one of our import Robots to acquire and transcode massive media libraries.
Handling uploads
We are the experts at reliably handling uploads. We wrote the protocol for it.
Front-end integration
We integrate with web browsers via our next-gen file uploader Uppy and SDKs for Android and iOS.
Back-end integration
Send us batch jobs in any server language using one of our SDKs or directly interfacing with our REST API.
Pingbacks
Configure a notify_url to let your server receive transcoding results JSON in the transloadit POST field.
On-demand
Use our Smart CDN to adapt files on-demand and stream them directly to your users.
Video encoding
Document processing
