Hi i am using custom FFMPEG to change a video to a certain format.
in my commands i have used the video bitrate of 15Mbps but when i put the scale filter to 720x576, the video bitrate isn't going past 4Mbps after so many attempts on altering the commands.

Any ideas what the problem can be?
Thanks

This is an impossible question to ask without know your command line. But you will have to search the web for constant video bit rate. Just setting a bitrate usually means variable bit rate adapted to the compexity of you video.

This is the command I am using for my custom FFMPEG. I have set the video bitrate as 15Mbps, and video codec is mpeg2video on the video option.
When I run this command, the video bitrate is only 8Mbps now. The original video bitrate is 114Mbps.

Any idea what I can be doing wrong?

Well, maybe you can try this:

-pix_fmt yuv422p -r 25 -non_linear_quant 1 -flags +ildct+ilme -top 1 -dc 10 -intra_vlc 1 -qmax 2 -lmin "1*QP2LAMBDA" -s 720x576 -minrate 15M -bufsize 600000 -ar 48000 -ac 2
