A new video has been released by Omashay . Here is Goodnight, on which I did the slow-motion:

The video is based on a series of 70 sketches Tomasito’s made for a college project:
He wanted to explore the possibilities of reusing them for a music video. I had the perfect secret weapon for this kind of job: slowmoVideo , an open-source clone of Twixtor .
In fact I tried to use that software 14 months ago, but never went as far as producing something. First I realized I had no
nVidia GPU
cg1.4xlarge
) from Amazon’s cloud. It cost me $4.70 (without VAT) for 3 hours. But I failed to compiles slowmoVideo.
I forgot about it until recently, when I learned it no longer required a GPU to compute the optical flow. And last month I found a way to compile slowmoVideo on Ubuntu 12.10 .
Now it’s time to prepare my keyframes. I batch-resized all original drawings to 1080p with a white background. This was done in one command line thanks to
ImageMagick
$ convert -resize 1920x1080 -background white -gravity center -extent 1920x1080 ./keyframes/* pict%04d.png
Then I applied a paper texture to add some grain:
$ find ./ -iname "pict*.png" -exec composite -gravity center -compose Multiply ./paper-texture.png "{}" "{}"-texturized.png \;
The series of images were imported in slowmoVideo, and I created a 4 minutes linear ultra-slowmotion with the default parameters.
Finally, the raw rendering was assembled in Kdenlive with Goodnight’s audio track and title cards to produce the result that is now available on YouTube .
