Lotus window presentation¶

Lotus window video¶

※ The windows in the video open and close at quadruple speed. x4

ffmpeg¶

I used an app called ffmpeg to compress the video size. You can easily change the video size and extension by simply entering a command from the terminal.

$ ffmpeg -i lotus_window.mp4 -vcodec libx264 -b:v 750k -vf scale=-2:1080 -acodec mp2 -b:a 256k -ar 48000 -ac 2 presentation.mp4

But the problem is… There is no sound!

I got some advice from the instructor. (Less than) What about -acodec mp2 -> -acodec aac? (Use aac instead of mp2 for voice codec)

$ ffmpeg -i lotus_window.mp4 -vcodec libx264 -b:v 750k -vf scale=-2:1080 -acodec aac -b:a 256k -ar 48000 -ac 2 presentation.mp4

This time it’s perfect.
