Low quality without rendering text

Post by rickemail »

Hello, I noticed that bludisc uses a different font system than some bluray projects, the font file is saved in the "AUXDATA" folder

Below I will leave an image showing the difference in quality between: Not rendering text to image, and Rendering text to image.

In powerdvd the difference between them is quite big, rendering the text to image the quality is much higher.

The problem is that I cannot render the text to an image because I use the command in the project:
manager.getChapterTimeByNumber
If the text is rendered it does not modify the text for the corresponding chapter.

And I also use the command:
manager.time2str(manager.getMediaTime
In the time menu, some commercial blurays use the font file in .bin format, the text characters are rendered directly in the png like the attached image.

Kaleidoscope also works with font files in .bin and png

Would it be possible to improve this issue in the bds in the future? Because as I said before, I can't render the texts in an image, otherwise the commands won't work.

I made a video of the movie Stargate showing the quality of the time text running on PowerDVD, it's beautiful and without aliasing.
I saw that you update the program almost every week, I asked this question just indicating an improvement for the tool, thank you

Hello,
at the moment I don't see any way to change this. Maybe later.

What you see in Kaleidoscope is using pre-rendered fonts.

On the last screen there are 2 different fonts. If this was the same font - look for another font. Some fonts have problems with using them directly on the player. Without render to image means that the player renders it.
Best regards,
Alexey Kolesnikov

Thanks for the answer, if you can put the font rendered in png it will be perfect, I noticed that this problem is related to the version of PowerDVD, versions below 23 use directx9, version 23 uses directx11, I don't know if this It implies the way the player renders the text but it's the only change I noticed.
