The popular open-source VLC video player was demonstrated on the floor of CES 2025 with automatic AI subtitling and translation, generated locally and offline in real time. Parent organization VideoLAN shared a video on Tuesday in which president Jean-Baptiste Kempf shows off the new feature, which uses open-source AI models to generate subtitles for videos in several languages.

It's already available for anyone to use. https://github.com/openai/whisper

They're using OpenAI's Whisper model for this: https://code.videolan.org/videolan/vlc/-/merge_requests/5155

Note that openai's original whisper models are pretty slow; in my experience the distil-whisper project (via a tool like whisperx) is more than 10x faster.

Has there been any estimated minimal system requirements for this yet, since it runs locally?

[–] WalnutLum@lemmy.ml 11 points 2 days ago* (last edited 2 days ago) (1 children)

It's actually using whisper.cpp

From the README:

Memory usage Model Disk Mem tiny 75 MiB ~273 MB base 142 MiB ~388 MB small 466 MiB ~852 MB medium 1.5 GiB ~2.1 GB large 2.9 GiB ~3.9 GiB

Those are the model sizes

Oh wow those pretty tiny memory requirements for a decent modern system! That's actually very impressive! :D

Many people can probably even run this on older media servers or even just a plain NAS! That's awesome! :D
