Lambda transcode-video function will not create folders as described in the book.

[dolabriform]

In order for an output folder to be created in the transcode bucket, the folder needs to be prepended to the output path for each of the versions:

Outputs: [
{
Key: outputKey + "/" + outputKey + '-1080p' + '.mp4',
PresetId: '1351620000001-000001' //Generic 1080p
},
{
Key: outputKey + "/" + outputKey + '-720p' + '.mp4',
PresetId: '1351620000001-000010' //Generic 720p
},
{
Key: outputKey + "/" + outputKey + '-web-720p' + '.mp4',
PresetId: '1351620000001-100070' //Web Friendly 720p
}
]};
