Best software for subtitles

[augerpro]

So....is what I posted above something that customers would like to see improved, or no interest??

Hi augerpro:
If you want gain the more of quailty with the a profile. Just edit the perset of them:

*For the BD copy, please edit the belwo profiles:
X:\Program Files (x86)\DVDFab 8 Qt\BDMV\x264_dp_Standalone-Blu-ray.xml;x264_dp_Standalone-Blu-ray_Fast.xml.

*For the BD ripper(eg: bd_mkv.h264.audiocopy.xml):
Please find the string:
<perset enable="0" key="x264_ABR_Fast.preset" owner="" template=""/>

It is mean the profle bd_mkv.h264.audiocopy.xml uses the "x264_ABR_Fast.preset" .
If you want to improve the quality, just change the settins you want.

I make a better x264_ABR_Fast.prese which refer to your sshot.
Below are the changes:
<NbBframes>3</NbBframes>
<NbRefFrames>3</NbRefFrames>
<SubPelRefinement>7</SubPelRefinement>
<METype>2</METype>
<P8x8mv>true</P8x8mv>
<B8x8mv>true</B8x8mv>
<I4x4mv>true</I4x4mv>
<I8x8mv>true</I8x8mv>
<P4x4mv>true</P4x4mv>

Performane and quality are pry, you choose.

Thanks,
Poti

MUCH appreciated Potti!! I'll see how this looks this weekend. BTW what is a common program that can open and edit a .preset file?

[signals]

Notepad. They are just text files.

Just a quick look at the same screenshots above and I don't think I really see a difference. It should be at least equal to the other software, if not slightly better. I keep reading that x264 does support Quick Sync, does editing these presets really have any effect? I've only been using DVDFab utilizing QS, not software or gpu modes.

Should have typed "x264 does NOT support Quick Sync"

[augerpro]

So it appears that Quick Sync's presets are all hardcoded, changing this preset file does nothing when using Quick Sync. Here is response I got from Petter Larsson of Intel at their Media SDK forum (Media SDK being the layer that other softwares use to access QS):

"Media SDK exposes 7 levels to control encoding quality. Application that uses Media SDK to access the QuickSync encoder capabilities decides on what quality level to use and how to map it to a user option.

If you need to know this mapping I suggest you contact the individual application vendors. They may be able to share this information.

If you want to play around with the encoder quality levels exposed by Media SDK directly I suggest to take a look at the encoder sample that is part of the SDK package."

Arcsoft Media Converter and Mirillis give some varying access to the user via a single Quality setting, but since DVDFab does not, I'm assuming they simply selected one to use with no choice for the user (and it is not the best one). Would it be possible to add access to these 7 quality levels? Everyone I'm talking to on HTPC forums would probably only be interested in the highest level (still trying to find out exactly what the settings are in this level and how they compare to my settings in the software I compared with in this thread.)

[augerpro]

If DVDFab just wants to a great ripper (and it is) that is cool, then chuck the video converter functions. If you want to be a great video converter too, you're going to have to take topics like this seriously.
