# Video encoding, subtitles conversion, etc. tasks for "Time Bomb"

# TODO(jeff): Swap out use of ffmpeg in favor of x264 for encoding.
#
# mp4box -add previews/mpeg2/ch4_doggy-pounding.mp2 chapter4_doggy-pounding.mp4
# x264 -o ch3_tb.mp4 ch3_tb.mpeg2video
#

# TODO(jeff): Do video deinterlacing **first** so that we can then use it as
# the input media for further encoding tasks.
# TODO(jeff): Once the above task is completed, remove the deinterlacing flags
# from the web task.

# TODO(jeff): Implement makefile task for subtitles
