Subtitle Background missing from some letters

[jaydeep.vayeda]

Description of problem or question: I am facing an issue where color of background is missing from a select letters. Kindly refer to below link to download the image of issue where letter "t" is missing black background. For other videos the problem persists only with 3 letters in lower case i.e. "t", "i" & "f". I am using .mp4 video and .ssa subtitle files which I converted from .srt file. I am not able to figure out why is this problem persisting. I did a batch processing of 167 files by uploading them in queue and mapping a subtitle file with respective video. I have this issue in 20 odd file only. Rest are fine. I need help to understand why is this happening and how to fix this.

The Calibri font that the SSA file requested mapped to Calibri-Bold on your system. Does the SSA file specify a background color around the characters? Usually a transparent background would be used.

Hello Woodstock,

So kind of you for prompt reply. I hope you are safe.

While converting .srt to .ssa I selected substation alpha and selected the option of opaque background. So yes SSA file does specify a background and while defining the settings I can see the black background in the preview.

Warm Regards,
Jaydeep
