You have to force an aspect ratio to get the output you want, use the

Hello,
I'd like to overlay the audio waveform coming from an axis camera's stream.
I've started to read the documentation, but It's quiet complex. For testing
I use that bunny stream.
So far I managed to pad a bottom:
#!/bin/bash
stream="rtsp://184.72.239.149/vod/

-minrate 100 -maxrate 150 -bufsize 200 -preset fast -profile:v main

agree, Michael. The documentation[1] does not mention which output

Just pick a bigger width for the scale and pad filter, and then add
crop as the last filter, cropping to the final resolution. Add crop
with another comma to the filter chain as you did with scale and pad.
Also, have a look at the filter documentation:
only 2.35:1 is visible.
Have a look at the documentation for the "pad" filter.
The following example might work, but I haven't tested it:
ffmpeg -i input.mp4 -vf pad=x=-1:y=-1:aspect=2.35 output.mp4

ions are W x H.
I assume your watermark is correctly sized and smaller than W/10 x H/10.
If not, add a scale filter before the pad in the command below.
Command would be
ffmpeg -i video.mp4 -loop 1 -i image -filter_complex
"[1]pad=W/10:H/10:(ow-iw)/2:(oh-ih)/2:color=black@0,tile=10x
;F:\scaler
Since you're scaling proportionally ("-1:1080"), you need to pad out the
frame to FHD.
ffmpeg -i in -vf "crop=720:576:0:32,setfield=tff,yadif=1:0:0,
scale=-1:1080,pad=1920:1080:(ow-iw)/2:(oh-ih)/2,

Pad the vide

scale and pad the video to create a letter box formatted output.

mmand resulted in the video being cropped to a square

then you could pad the video before applying the rotate filter, and crop
it after the rotate filter:

rted in between.
It is correct:
https://ffmpeg.org/ffmpeg-filters.html#Filtergraph-syntax-1
If an output pad is not labelled, it is linked by default to the
first unlabelled input pad of the next filter in the filterchain.
