Is there a good MP4 to WebM converter for MacOS like MasterOfWebM

ffmpeg

>>57416378
I need something with an easy to use and simple GUI
ffmpeg looks like hacker stuff

>>57416324
That's a big pizza.

>>57416416
Feel free to grab a bite buddy.

>>57416416
for you

>>57416397
"ffmpeg -i input.mp4 output.webm" is really hard

>>57416477
But I need it without audio and at a 3MB filesize limit and this looks confusing

>>57416506
>without audio
-an

>>57416324
Holy shit...

>>57416844
what's the problem my good man

>>57416324
That had to go in the bed of a pickup truck

>>57416506
>3MB filesize limit
your bitrate is 3000 kB / 55 seconds, then 3000/55=54kB/s

-b:v 54k

>>57416324
Found your mammas size-type of pizza, oh wait...

>>57416477
enjoy your 60 qmax on 100kbs bitrate

>>57416506
if you want to get the exact size

First, determine the correct bitrate in kbps, theoretically it should be

(1024*1024)*3*8/t

but ffmpeg tends to over shoot, so in my experience

(1012*1024)*3*8/t

works better.

Then just two pass it

 ffmpeg -i input.mp4 -an (no audio) -vcodec libvpx (vp8 instead of vp9) -pass 1 -b:v [bitrate we determined earlier] -y a.webm && ffmpeg -i input.mp4 -an (no audio) -vcodec libvpx (vp8 instead of vp9) -pass 2 -b:v [bitrate we determined earlier] -y a.webm

THAT PIZZA

>>57416923
ffmpeg works in KiBs (1024)

>>57416324
That's clearly four square pizzas

>>57416949
that is an interesting piece of information

what do the numbers in

(1024*1024)*3*8/t

refer to though?

Settle down, you butthurt dumb boys. Also, I'm an intelligent beautiful woman.

>>57416997
Oh, my bad

1024 bytes * 1024 bytes (megabyte) * 3 (3 MB) * 8 (we need bits, not bytes)

>-i
input

>-b:v
bitrate:video
b:a would be audio bitrate

>vcodec
video codec
can also be written as -c:v
-c:a/-acodec would be audio codec

>pass 1/2
2 pass encoding, analyzes the ile beforehand to improve efficiency and be able to predict file size.

>-y
assume yes (overwrite file)

For lbigger files I would also add

>-cpu-used 0
encode slowly and efficiently, goes from 0 to 5

>-quality good
better quality, options are realtime/good/best.
Best is an overkill, never worth it

>-threads 4
multithreading


if you'd want to take a segment from a file

>-ss
starting position
can be written as minutes:seconds
is you put it before -i it would seek way faster but would be slightly less accurate

>-t
how long should it be

>>57417219
Thanks.
But doesn't (1012*1024)*3*8/t (I assume t is the length in seconds?) give you a ridiculous bitrate?
Or maybe I'm missing something

>>57417330
the bitrate is in bits per second

We heard you and your mother were coming to visit.

>>57416324
What do those white things do all over the pizza?

>>57419853
they keep the ceiling of the box from touching the pizza

>>57416324
Going to be hard to do. WebmConverter is one of the most based programs to come out in years. It is a definitive example of simplicity while meeting the demands of the user.
