Select the right title first
The main-movie suggestion is a starting point. Change the title when it does not match the recording you need; both Free and Pro allow this.
Listen before converting
Review the sound selection beneath the preview. A language label may be incomplete, so listen to a representative passage rather than relying on the label alone.
Check the subtitle result
Choose a subtitle track if the title exposes one. Text already burned into the original picture cannot be switched off. Test the saved file in your intended player; picture cropping may require burning the selected subtitles into the picture.
