Understanding French MP4 files
French varies noticeably between Metropolitan (European) French, Canadian French (including Québécois, with distinct vowel sounds and vocabulary), and the many African varieties spoken in countries like Senegal, Ivory Coast, and the Democratic Republic of the Congo. Belgian and Swiss French are close to the Metropolitan standard but use different number words (septante, nonante), which matters when verifying figures in a transcript.

Frequently asked questions
How to improve the accuracy of your French transcripts?
Start by improving the quality of the French MP4 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 French MP4 file that I upload?
Yes, please do not over-compress or over-filter the audio track of your French MP4 file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MP4, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in French with Sonix:
Do I need to extract the audio from an MP4 before transcribing it?
No. Because MP4 is a container that holds both video and audio streams, the audio track can be read directly from the file, so you can upload the video as is.
Why does my MP4 file play video but no sound?
The file may contain a video stream with no audio track, or its audio may use a codec your player does not support. Checking the file's stream details in a tool like VLC or re-exporting it with an AAC audio track usually resolves the issue.
Can Sonix transcribe Canadian French?
Yes. Sonix transcribes French audio from Canada as well as Europe and Africa, and the in-browser editor lets you review and correct any regional vocabulary while listening to the synced audio.
Does French transcription handle accents from African countries?
Sonix accepts French recordings from any region, including Francophone Africa. Because the transcript is stitched to the audio, you can quickly verify passages with regional pronunciation or code-switching and fix them in the editor.
Can I export French subtitles from my transcript?
Yes. After transcribing a French audio or video file, you can export the transcript as SRT or VTT subtitle files, as a Word document, or in dozens of other formats.
