can i show subtitles over video at the same time ?

Upload a tarball with debugging information

1. Run the command that produces the out-of-sync subtitle output, but with the additional --make-test-case flag, i.e.: subsync ref.mkv -i in.srt -o failed.srt --make-test-case
2. This results in a file of the form ref.mkv.$timestamp.tar.gz or similar.
3. Please upload this file using the "attach files" button at the bottom of the text prompt.

That's all! Thank you for contributing a test case; this helps me to continue improving the sync and to add additional integration tests once improvements have been made.

i know after this proceess subtitles show slightly show earlier than video. but in some movies like having language which i know needs sync subs to video exact same time. so what i want is to make subs sync to video with exact same time. is that possible ?? thanks in advance.
