1. Swapping to disk would kill the performance to an unnacceptable level.

2. I'm assuming video editing software works on a raw format in memory with access to individual frames? Just like Photoshop would need access to individual pixels from an importend JPEG, the actual canvas uses a lot more memory than the compressed input format.

That's correct, access to each pixel of each video frame is needed. Each video frame must be inflated from its codec compression.
