Supported formats
Check local video/audio inputs, SRT subtitle import and export options including SRT, VTT, TXT, LRC and CSV.
Broad media support with a clear container/codec caveat for unusual files.
Supported Formats
Voice2Sub is designed to open a broad range of common and many less common video or audio files directly in the desktop app. That includes real-world files from phones, cameras, screen recorders, editing apps, podcasts, lectures and voice recordings.
Download Voice2SubReview step
Use format support to open common media and SRT subtitle files, then review generated output before choosing the final export format.
Workflow
Check compatibility before format-heavy work such as MP4 to SRT, MP3 to transcript, VTT for web players or CSV review handoffs.
Start from MP4, MOV, MKV, AVI, WebM, MP3, WAV, M4A, FLAC or another supported video/audio file.
Voice2Sub recognizes speech and creates subtitle or transcript text you can review.
Export SRT, VTT, TXT, LRC or CSV based on where the result will be used.
Supported formats
Voice2Sub is designed for broad media support: common containers and many less common real-world video or audio files from creators, cameras, phones, screen recorders, podcasts, lectures and editing apps. If a familiar container uses an unusual codec, open it in Voice2Sub to confirm compatibility before a long workflow.
Import videos from phones, cameras, screen recorders, editing apps and archive folders.
Import recordings, podcasts, interviews, lectures, meetings and voice notes.
Export SRT, VTT/WebVTT, TXT, LRC or CSV for publishing, editing, transcripts and review.
File extensions are examples. Containers such as MP4, MOV or MKV can hold different codecs; unusual or proprietary codecs should be tested in the app before long processing jobs.
Export guide
Choose the output based on where the subtitles or transcript will be used after review.
Use SRT or VTT when you need a standard caption file for publishing workflows.
Use VTT/WebVTT when the destination is a web video player or HTML5 caption workflow.
Use SRT for broad compatibility or CSV when structured timestamp/text review is useful.
Use TXT when you need readable text for notes, search, documentation or handoff.
Use LRC when line-by-line timestamps are helpful for lyric-style or timestamped text workflows.
Container vs codec
MP4, MOV and MKV are containers. They can hold different audio/video codecs inside the same extension. Voice2Sub is built for broad real-world compatibility, but very unusual or proprietary codecs should be opened in the app first before a long processing job.
Input coverage
Check real source files from cameras, screen recorders, meeting tools, podcast workflows, lectures, interviews and editing software before committing to a long processing run.
Import and output coverage
The media picker accepts the listed video and audio extensions. The current subtitle editor imports SRT files, while generation outputs SRT, VTT, TXT, LRC and CSV. Each list serves a different stage of the workflow.
Conversion rule
For common video and audio files, start with the original media. Convert only when a file cannot be opened, uses an unsupported codec, or comes from an unusual tool that created a nonstandard stream.
AI Transcription
Voice2Sub also covers speech to text, audio to text, video transcription and Whisper AI transcription, so subtitle generation can stay connected to transcript and export needs.
Format examples
These examples match practical long-tail questions such as MP4 to SRT, MOV to captions, MP3 to transcript, WAV to text and VTT for web players.

Yes. MP4 is a common video container supported by Voice2Sub. Codec compatibility can still vary for unusual files, so test unfamiliar media before a long workflow.
It creates the source-language subtitle output and an additional English subtitle file. The English filename adds an `.en` marker before the selected format extension, for example `video.en.srt`.
Yes. Import an MP3 or WAV audio file, generate text with AI recognition, review the result and export SRT when timed subtitles are useful.
SRT is widely used for subtitle exchange and review. VTT, also called WebVTT, is common for web video captions and some publishing workflows.
A familiar extension can contain an uncommon codec. Open the file in Voice2Sub first to confirm compatibility before committing to a long processing job.
Usually no. Start with the original video or audio file when it is a common format. Convert only if the file cannot be opened or uses an unsupported codec.
Voice2Sub can generate subtitle and transcript files such as SRT, VTT, TXT, LRC and CSV. Availability can depend on the app build and workflow.
Download the desktop app, open video/audio from your computer, review the result, then export SRT, VTT, TXT, LRC or CSV.
