As to why such high bitrate at 13mb,the quality depend on the source video will be blocky bad quality @1920x1080 at lower bitrate below 13mb.

The only slightly to get better quality is not to use the GPU acceleration for lower bitrate only use your CPU.

Hi Francisco -

I'm not sure why the bitrate can't be customised lower than 13MBps for a 1920x1080 MPEG-4.

The only way to do it in PD is to modify the Profile.ini - here's how you can make an MPEG-4 profile with the bitrate you want (say 6000 kbps).

1. In the Produce module, select MPEG-4 Best Quality (1920x1080) & click the + button to make a custom profile
2. Set the bitrate at 13000kbps (which is the minimum allowed)
3. Give the profile a name if you like, or remember its label (I just called mine TONY 3)
4. Save your project & close PD (not completely necessary).

Now - go to C:\Users\user name\AppData\Roaming\CyberLink\PowerDirector\10.0 and locate "Profile.ini"

5. Open the .ini file in notepad
6. Locate the custom profile you just made (it'll be the last one)
7. Scan through the text to find "<Video BitRate>13000000<Min BitRate>6500000<Max BitRate>13500000<"
8. Change the numbers to 6000000
9. Save & close notepad

Now - open your project in PD & go to Produce > MPEG-4 & select your custom profile from the dropdown menu. Mine's named BEST 6MB so it's easy to find.

10. Name your video & hit Start.

The profile you just created will always be available to you in the Custom dropdown.
