Most modern media players (like VLC or MX Player) allow you to toggle between the original language (e.g., English) and a dubbed version (e.g., Hindi, Spanish, or French) instantly.

Encoders use codecs like HEVC (x265) . This format is much more efficient than the older x264, allowing for 720p or even 1080p resolution at a fraction of the file size.
