Gokaiger 5 March 20, 2011 Commentary by Sen-chan (Itou Yousuke)
So this is an interesting release for us. Ever since we found the footage for this, we've known that we wanted to do it. (I believe it's just from Itou Yousuke's ustream archive, so you might be able to downloads/stream the full thing still)
The thing is... there was a large technical hurdle. We knew we wanted to overlay Sen's video onto the actual episode itself, but we didn't know how. We thought we'd need some crazy video editing software or something. (Turns out it's actual a very simple filter in avisynth.)
The other problem we had is that we didn't know how long the commercial breaks were (they're not included in our raws). So I had to kind of guess on that based on Sen's comments. Not a bad job, eh? The actual sub is from the Blu-ray rip, but the 199 Heroes promo at the end is from the original release. You have no idea how convoluted my setup was at the end XD
Sorry for the sloppy composition for the first few clips. As you may have gathered, Sen-chan (Itou Yousuke) started his video feed nearly 40 minutes before the show started. So I wanted to sub some stuff, but cut out the hundreds of "Good morning!" "Here's the number of people watching the feed now!" filler that was the first 37 minutes.
Other random things to take into consideration was where to position's Sen's commentary lines during the actual show and where to put his video. Originally Sen's video covered up the bottom subtitles, but I was able to clip it so that it's visible now.
