I hope I'm getting your intention right here. I had to do this a while back
for some PAL files. Split the fields, scale, pad, then interlace.

Is a pillar-box recommended when transcoding to HD? I thought they were
generally discouraged or am I mistaken?
Hi All,
I was hoping for some advice regarding the best way to sequence video
filters when transcoding SD video to HD, de-interlacing, scaling, padding
(pillar-box), etc. I know the order of filters is critical, but I haven't
been able to determine if one way of doing this is better than another.

Thank you.
I'm trying to convert an mp3 file to ogg file to send through to a WhatApp
contact through their API. The Whatsapp API only accepts " audio ogg-file in
opus codec". I convert it using

That’s good, but in that spirit, you should look up what top-posting is and
avoid doing it in this mailing list.

I need to convert with the following settings:
Bitrate of 19.1kbps
1 channel
Sample rate of 16.0khz
How would that look in:
ffmpeg -i audio.mp3 -c:a libopus newfilename.ogg
Is the Writing library " Lavf58.28.102" the same as "WhatsApp"?

Good catch, it probably tried to write a file named “c:a” and asked for an
explicit format

Seems fine to me, you might want to add some encoding options and obviously
wrap it in a shell exec function or backticks(?) to do it in PHP. Sorry I’m not
up to speed on PHP, but that notwithstanding you didn’t even mention which
