Haven't changed this yet... My thinking here was that if the video ID isn't already in the s3 bucket, then it needed to be added to the <code>formats_to_convert</code> dict that you use further down in <code>export.py</code>. I didn't know how to check that without referencing <code>converted_formats</code>. 

If the <code>missing_on_s3</code> flag was set along with the language channels flag, <code>converted formats</code> wouldn't be defined yet, so I defined it inside <code> if language_channels:</code> to be safe.
