Download of longer videos (49min) takes a lot of time to start

The video processed fine and is viewable in the built-in player, but when it was time to download it, it didn't work.

The snackbar appeared and that was it. Downloading smaller videos (1min) worked fine.
After trying to download this larger one, trying again to download the smaller one also failed.

Update: after about 2 minutes, Chrome started to download it (as it is a local file, it downloaded instantly).

As a user, I would just assume it failed. We should consider that as a critical bug.

Just tested and a 10 minutes video is taking 15 seconds to start downloading. 40 seconds for a 22min video.

From my tests, what is taking a lot of time is the process of zipping the files. It's strange, since this didn't use to take long on the old implementation, but the code does not seen to have changed significantly on this part.

Got the problem: in the old implementation we had the option to download only the video file separately, without zipping, and this was fast. When zipping, even in the old implementation, it was taking the same time.

PS: git is a magical tool.
