Subtites - Font size

[vids20]

Hello I am trying to play a .MP4 file on my Android Phone and using an application called "QQPlayer"
The fonts of the video are hard coded.

The fonts size of the subtitiles are too small and as it is hardcoded it is not recognized by the application as a Subtitle file and unable to increase the size from its setting.

Can anyone help me ,any way of increasing the font size???

Nope. You can't increase the size of hardcoded subtitles. Other than zoom the entire video.

Only way is to get text subs (e.g. SRT, ASS) and use them as well.
Of course, the original subs will still be there in the background.
