A problem I came across while burning a DVD

Hello everyone,

I came across a technical problem during work and I would be grateful to hear the solution from the experts, please.

I had a blu-ray DVD that I needed to add subtitles to (.srt), I used Handbrake on MAC and exported an m4v file with the subtitles and everything looked perfect, noting that I had soft subtitles because Handbrake wouldn't allow me to choose the hard option.

Moreover, I wanted to burn the film on DVD via Toast Titanium and the result was a perfect film but utterly tiny subtitles.

What was the problem here? Could someone assist me, please?

Thank you so much for your guidance and help in advance.

Have a nice day.


Best Regards,
Elias Abu Ata
