Making webm files
Yesterday I posted a stupidly large gif of some pumpkins flashing different colours. Then a couple of minutes later after suffering through the upload I replaced it with a teeny webm.
ffmpeg
now has excellent webm support, for me it will happily pick it up with
automatic detection. To make videos like the one above I use
ffmpeg
and let it
choose its own options. I drop the audio from the video to give it a nicer gif
like effect, I think from today I will tell browsers to autoplay the video
snippets so they look like awesome gifs.
I do something like this:
$ ffmpeg -i VID_20161030_112003.mp4 -ss 00:00:02.0 -an coffee.webm
-
-i
is the input video -
-ss
tellsffmpeg
to start the encoding at this time stamp- we could pass -t to tell ffmpeg to extract a t length section of the video
-
-an
tells us to the use no audio -
coffee.webm
is the output video and format,ffmpeg
will do the right thing here
