A good idea but why did you re-encode that low quality video? This "This is Not A Mommy Movie" source file has just A/V bitrate of 1199 kb/s and you did encode the TC video part with 8078 kb/s! So you know that it makes no sense right. The quality is not getting better and you just increase the file size unnecessarily. Your TC video has now a file size of 545 MB what is a way too much. Anyway, for all who are looking for the easiest way to get that TC video out is to just make a key frame cut only (~ every 2 seconds in this video) and the cut has a final size (no re-encoding just copy mode) of 76 MB only compared to your 545 MB cut. Just for people who are interested and for all who don't like to waste free space we don't have to give away.
