MPEG Videos Created + Subtitles!

It's been a while since I've made an entry here but work continues! Andy's been hard at work on the score to FvTWM. I've heard a couple of demos of cues so far and I'm told it will sound even better once it's given the full orchestral treatment through East West.

In the meantime, I've made the DVD-ready MPEG 2 video files for the three versions of the movie: a 2D version, 23.976 frames per second, progressive 480p 16x9; an anaglyph 3-D version, 23.976 fps, progressive 480p 16x9; and a field sequential 3-D version, 29.97 fps, interlaced 480i 16x9. I haven't been able to test the field sequential version yet but the other two are working quite well.

Recently a new 3-D DVD hit the market, a remake called Night of the Living Dead 3D. The 3-D effects are better than some videos I've seen, but the producers solution to ghosting images (where you see double images even with the glasses on) is to keep the depth in the frame pretty shallow. Frankenstein vs the Wolfman sometimes uses "super-depth" in it's images so I had to work to find another solution.

I've outlined this process in a prior blog entry but I use the Night of the Living Dead 3D disc as an example: in each sequence of that movie, when you close your blue eye and look through the red lens, everything appears extremely dark. My solution was to boost the gamma of the red eye view so that the picture through the red lens appears as bright as that seen through the blue eye. This has served to lessen the effect of ghosting and produce a more satisfying anaglyphic 3-D experience.

I'm happy to report that the MPEG compression's color matrix did not have an adverse affect on how the red and blue colors are reproduced (unlike the YouTube video compression - which I believe is Shockwave Flash.)

Also, I've been working on subtitling the movie, using Adobe Encore. It's a pretty nice setup, allowing you to type your subtitles directly onto the monitor window. These subtitles will only be available on the 2D version of the movie (they ruin the 3-D effect on the 3-D versions) and can be chosen by selecting the subtitle track once the movie has started.
