Your FFmpeg version is much too old. You should update it.

You should always show the command line and the console output when

Hi,

The bitrate is already below 5Mb/s, look at the end of the console output:
bitrate=3772.4kbits/s

Aspect ratio, width and height are also the same:
Input: 1920x1080 with 90° rotation in metadata
Output: 1080x1920

It seems I don't understand what you want to do.

I don't think that the input video contains black spaces. The input 
video is 1920x1080 and it has "rotate=90" set in the metadata. That's 
why FFmpeg rotates the video and the output is 1080x1920 and there are 
no black spaces in the output.
If you don't like this output, what do you want instead? Do you want to 
cut off the top and botton part? Then you must use the crop filter.

Actual Input what i am using

It seems the input is 1920x1080 but the output is 1080x1920. I don't yet 
understand why.

Does the original video look ok if you play it in VLC or FFplay?
Does it work if you add -vf scale=1920:1080 ?

Thanks, Micheal

Here is the command, I am using to reduce the bitrate.

ffmpeg -y -i original.MOV -b:v 4.5M -map_metadata 0:s:0 -c:v libx264
-preset superfast -tune film -ac 2 -c:a aac -maxrate 4M -bufsize 3M -strict
-2 -vf scale=iw:ih -f mp4 output1.mp4


Please show also the complete console output.
I think -vf scale=iw:ih can be omitted. It's useless because it means 
"leave the width and height as it is".

Re: [FFmpeg-user] Regarding video compression

Thanks, Archana.

I am having a doubt. I want to remove the black area of the video as I
mentioned above-left side and right side black area. Does FFMPEG have any
command for that?
