Questions and answers

Where does the second part start when I join CD1 and CD2?

At the length of the first video part. The tool suggests the end of the last line of the first file; for an exact result, type the length of the CD1 video.

Can I show two languages at once?

Yes, with our bilingual subtitles tool, which puts two languages in one subtitle file.

The two files have different formats. Is that a problem?

No. Each file is read in its own format and the result is saved in the format you choose.
