Can you repeat the problem? If so, what are the steps?
I’ve been editing videos and adding subtitles for days. But suddenly, the new subtitle tracks don’t show up at all. I’ve tried erasing them and starting all over again, adding the filter first, then, adding the filter from the subtitle menu. The thing is, I already have subtitle tracks on the same video and those are perfectly fine. This started when i closed the proyect I was subtitling, opened a second proyect to export it, and then opened the proyect I was first subtitling to keep working on it while the second proyect was exporting.

I waited until the second proyect was done exporting, closed the program, and opened it again. But everytime I add a new subtitle track and filter, it doesn’t show up on the preview.

FYI, I’ve already subtitled two other videos of 15 to 20 min length with no issues.

Subtitles do not show on the preview player unless you add a filter to the output to show them.

From the subtitles menu, choose “Burn in subtitles on output”
