Frequently asked questions

What file formats are needed for audio and video localization?

We accept audio files in the following formats: mp3, wav, aif. For video localization, we accept avi, mov, mp4, wmv, and flv files. Please also specify any audio and/or video codecs specific to your files.

If on-screen text within the video needs to be localized, then you must provide the Adobe Premiere Pro, Adobe After Effects, or similar project file used to create the original video. Please also send details of the fonts used for the on-screen text and any trademarks or symbols.

If you’re unsure which file formats to use, our engineers will work with you to determine which formats will be most efficient for your project.

What’s the difference between subtitles and closed captions?

Subtitling refers to the original script of the video being transcribed, integrated into the video, and displayed at the bottom of the screen. Whether they’re source subtitles or translated subtitles, they are time-coded so each subtitle matches the speaker. Subtitles are embedded into the video so the user cannot turn them off.

Closed captioning means the text is hidden until selected (this applies to both source and translated material). This is the same as subtitling but sometimes includes descriptions of non-speech elements such as music and sounds. The user has the option to turn captions on and off.

What’s the difference between dubbing, lip-synching, and UN-style voiceover?

Dubbing is when an actor's voice in the target language replaces the original. Lip movements don’t match, but the voiceover is time-coded so the speaker starts and finishes at the same time as the original. This is the most widely used option.

Lip-synching is similar to dubbing, but the voiceover is synchronized to the original speaker’s mouth movements. This is a detailed and time-consuming process, and is a more costly option.

UN-style voiceover is when the original audio is turned down and replaced with the target language voiceover at a higher volume. The original speaker can still be heard and it’s obvious that the voiceover is an interpretation of what’s being said. This is commonly used for interviews.

How much does audio and video translation cost?

Our audio and video translation services are priced based on standard per-minute rates for each required service including transcription, translation, voiceover recording, subtitling, and on-screen text localization. Contact us for a free quote.
