What steps will reproduce the problem?
1. a file avi or mov
2. use this preset I made -s 480x320 -vcodec libx264 -b 260k -acodec libfaac 
-ac 1 -ar 16000 -r 25 -ab 32000 -aspect 3:2

3. convert 
What is the expected output? What do you see instead?
I expect to get an mp4 of lower size for mobile use but when I read the final 
movie info the kb are not 260kb+32 for audio but 720 or a bit lesser.

What version of the product are you using? On what operating system?
I run the version 1.3 on XP pro SP3

I don't understand where is the problem. I tried to add 200 in the video bit 
rate window option but nothing
thank you for helping me 
.

Please provide any additional information below.

Sorry for not responding for so long.

I think you might want to add a -maxrate 292kb to your preset. I am not sure, 
but I think you try to push the limits a bit. You might need to reduce your 
output size.

Please let us know if this helps.

Did you add all the parameters via the GUI or did you add it as extra commands 
in the command line options afterwards?

Can you cut and paste the script output into this issue?

I made a new attempt with an mp4 file bigger in size and dimensions to be 
converted with my preset added of -maxrate 292Kb but date speed rate it's 
higher.
I add screen shot and script issue

Well, there were issues with the conversion:

[libx264 @ 0x19697e0]Error: 2pass curve failed to converge
[libx264 @ 0x19697e0]target: 280.00 kbit/s, expected: 393.64 kbit/s, avg QP: 31.
0000
[libx264 @ 0x19697e0]try increasing target bitrate or increasing qp_max (current
ly 31)

I would try to follow the advise of ffmpeg and increase the target to at least 
393.64 kbits/s or increase qp_max...

Thank you. I'm using FormatFactory with video bit rate ranging from 230 to 
384KB/s and it works correctly. So I gave winff up I have no much time to make 
several tests.
Thank you for the helping.

As the OP didn't want to test, I set this bug to Invalid, as I think it is not 
a problem of winff, but too large demands for ffmpeg.
