We’re currently using non-resumable uploads which allows videos up to 1 GB and 20 minutes long (the most common videos).
This is the simplest implementation.
Resumable uploads on the other hand support videos up 10GB and 4 hours long.
This implementation is more challenging, but if a lot of people need this, we will get to work.
