The original WMV-3 file (and the extracted and converted to MPEG-4 portion of it) had a playback frame rate of 29.97 fps, and each 4th frame was duplicated. These duplicated frames were removed using HandBrake 0.9.4, resulting in an H.264 video file at 23.98 fps. That file was then converted to Theora format using ffmpeg2theora 0.27. But this relates only to the first version of this file. The latest version was converted via the following commands:
- mencoder -nosound -msglevel mencoder=1 -ss 0:27:42.9 -endpos 0:03:29.4 -vf pullup,softskip -ofps 24000/1001 -ovc raw VJSC_1425B.wmv -o VJSC_1425B-q1.wmv
- ffmpeg2theora VJSC_1425B-q1.wmv
- rm -f VJSC_1425B-q1.wmv
Comparing some known event times with their appearance in this film, it turned out that it was shot with a frame rate of about 35 fps, not the playback rate of 23.98 fps. So it must be taken into account that its playback is about 1.46 times slower than real time.

This version is inverse-telecined directly from the original file, thus reducing the conversion steps from 3 to 2. Conversion commands: mencoder -nosound -msglevel mencoder=1 -ss 0:27:42.9 - | ||
