A few video production notes

Here's some notes on making a custom thumbnail for videos.

To extract a single image:

ffmpeg -ss 01:42 -i foamy-cf.mov -vframes 1 foamy-cf-tmp.png

-ss timecode

-i input

-vframes 1   # single frame

Using ImageMagick:

convert -font Helvetica-Bold -pointsize 200 -fill white 

    -draw 'text 50,800 "First Line"'

    -draw 'text 50,1000 "Second Line"' foamy-cf-tmp.png foamy-cf-thumb.png

-font, -pointsize, -fill  specify appearance

-draw 'text x,y "foo"' draws text "foo" at position x,y
