I'd like to know how you overcome errors like 'moov atom not found', which I find very often in my process; I'm doing a similar job, but I'm using node.js in my case

That sounds like something specific to node. Not terribly familiar, unfortunately.

Unrelated question but have you found transcoding video to be especially slow with Node on Lambda? Harold mentioned a 10 minute video taking 105 seconds. I have a 30 second video that's taking over a minute to transcode. On my local system it takes seconds...

If you're doing it using ffmpeg, it should be about the same across any runtime.

Are you accounting for the time to download, etc? Also, it will always run faster on a local machine with real resources behind it, and the videos I'm transcoding are going to be relatively low-motion by nature.
