17. Machine design¶
This week we continued the machine building group work that started in the week 15. Our target was to automate our machine.
“VitaFab is an automated vitamin drink dispenser/maker. Every time you put a cup with water inside and press the button - it will make you a vitamin drink.”
The assignment required for “approximately 1 minute video to show your machine”.
First all of the material filmed during progress was gathered into overall viewing.
The video was edited in Sony Vegas 11 Academic.
In time line the video can be cut,paste,split speedup or otherwise manipulated. The usable parts are then put in a line to make the video.
Rest of the material is dragged onto the time line and text effects were added to explain the video.
The selected music was Music by No Copyright Music- Happy and Joyful Children 2:10. The duration was too long for our video and was edited to shorter version to fit the video length.
The final video looks messy in the timeline.
The video was first rendered out as a RAW format and then compressed using FFmpeg using the recommended settings from the academy site.
Code for the FFmpeg:
ffmpeg -i Master_piece_of_all_time.MP4 -vcodec libx264 -crf 25 -preset medium -vf scale=-1:1080 -acodec libmp3lame -q:a 4 -ar 48000 -ac 2 VitaFabPremium.mp4
This gives as the final video.
The music was selected because of two reasons:
- It has a happy feeling into it and the music fit the video.
