Understanding Portuguese MXF files
Portuguese has two major standards: Brazilian Portuguese and European Portuguese, which differ noticeably in pronunciation, rhythm, and some vocabulary. African varieties spoken in Angola, Mozambique, and other Lusophone countries generally follow the European standard, while Brazil itself has distinct regional accents such as Carioca, Paulista, and Northeastern speech.

Frequently asked questions
How to improve the accuracy of your Portuguese transcripts?
Start by improving the quality of the Portuguese MXF 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 Portuguese MXF file that I upload?
Yes, please do not over-compress or over-filter the audio track of your Portuguese MXF file. By uploading a high quality version of your audio, we can give you the best level of accuracy.
Aside from MXF, do you support other types of audio/video files?
Yes, we do! You can convert the following file types in Portuguese with Sonix:
Why won't my MXF file play in a regular media player?
MXF is a professional container, and consumer media players often lack the codecs it wraps, such as XDCAM or AVC-Intra. VLC or a professional editing application like Premiere Pro or Avid Media Composer can usually open it.
Do I need to convert MXF to MP4 before transcribing?
Usually not. You can upload the MXF file directly for transcription; conversion to MP4 is only needed if a downstream tool in your workflow does not support the MXF container.
Does Sonix support both Brazilian and European Portuguese?
Yes. You can upload audio or video in either variety, transcribe it, edit the transcript in your browser, and export it in a range of formats.
Can Sonix transcribe Portuguese audio with accented characters?
Yes. Portuguese transcripts include the language's diacritics, such as ã, õ, and ç, and they carry through to exported files.
Can I translate a Portuguese transcript into English?
Yes. After transcribing your Portuguese audio, you can translate the transcript into English or other supported languages and export the result.
Trusted by professionals worldwide
Was using another software before, but their prices went up. Your prices are better and the transcription seems more accurate. I also like that you automatically take out all of the filler words - um, you know, etc.
The interface and editor experience were great. I also like the way you handle speaker identification and naming. Pretty slick. Nice timestamp frequency / formatting too.
