Hi @msjindal,

We have seen a few problems like this occur when the video is not reliably seekable. Try reencoding your video and let us know how that works.

Update: If reencoding doesn't work, and results in moov atom not found

As I was helping a user, we found that they had just copied the contents of a zipped file over without unzipping which resulted in first the KeyError, and then, when attempting to reencode, a moov atom not found error. After retrying but with unzipping first, we were able to get everything running smoothly.
