Burning subtitle with custom font and style

[feureau]

Hi,

I'm trying to burn subtitles with custom fonts and styles using NVEncC64, but I can't seem to get it to work correctly. I've gone through the documentation and existing issues but haven't found a solution. I’ve tried Burning embedded subtitles directly:

I used the --vpp-subburn option to directly burn the subtitles embedded in the input video file. However, I couldn't find a way to change the font, size, color, or style when using this method. Is there any way to customize subtitle styles when burning embedded subtitles?

whenever I run NVEncC64, it always defaults to using the following font:

fontselect: (Arial, 400, 0) -> ArialMT, 0, ArialMT

Is there any way to force NVEncC64 to use custom defined font, including font, size, color, position, and shadow?

Thanks in advance for your help!

As there is no overwrite option in --vpp-subburn option itself, I think the way for this is to edit ass file it self as below.

[V4+ Styles]
Format: Name, Fontname, Fontsize, PrimaryColour, SecondaryColour, OutlineColour, BackColour, Bold, Italic, Underline, StrikeOut, ScaleX, ScaleY, Spacing, Angle, BorderStyle, Outline, Shadow, Alignment, MarginL, MarginR, MarginV, Encoding
Style: Default,Consolas,14,&H00ffffff,&H0000ffff,&H00000000,&H80000000,0,0,0,0,100,90,2,0.00,1,2,3,2,20,20,8,128
Style: black01,Consolas,14,&H00000000,&H0000ffff,&H00ffffff,&H80ffffff,0,0,0,0,100,90,2,0.00,1,2,3,2,20,20,8,128

NVEncC log

fontselect: (Consolas, 400, 0) -> Consolas, 0, Consolas

In this case, font "Consolas" was used in --vpp-subburn.
