Frequently asked questions
How to improve the accuracy of your Chinese (Cantonese) transcripts?
Start by improving the quality of the Chinese (Cantonese) M4V file that you upload to Sonix. Please use high quality recording equipment, recording in a quiet environment, and ensure that your speakers are speaking clearly to ensure that your transcript is as accurate as possible.
Any advice for the Chinese (Cantonese) M4V file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Chinese (Cantonese) M4V file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from M4V, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Chinese (Cantonese) with Sonix:
Why won't my M4V file play on my computer?
Movies and TV shows purchased or rented from the iTunes Store often carry FairPlay DRM, which restricts playback to authorized Apple apps and devices. DRM-free M4V files play in most modern media players, including VLC.
Can I just rename an M4V file to MP4?
Often yes, because both extensions use the same MPEG-4 container, so renaming a DRM-free file usually works. Playback can still fail if the file uses AC-3 audio and the target player does not support that codec.
Can Sonix transcribe Cantonese audio and video?
Yes. Upload your file, select Cantonese as the language, and Sonix generates a transcript you can edit in the browser and export to formats like Word, text, and subtitle files.
Does Sonix treat Cantonese and Mandarin as different languages?
Yes, they are separate language selections. Spoken Cantonese and Mandarin are not mutually intelligible, so choose Cantonese for Cantonese-language recordings.
Can I create Cantonese subtitles from my transcript?
Yes. After transcribing and editing, you can export subtitle formats such as SRT and VTT for use in video players and editing software.
