Whisper (OpenAI) - Automatic English Subtitles for Any Film in Any Language - An Intro & Guide to Subtitling JAV

[SamKook]

Seems odd to me that you have 2 different python folder involved(if you use a virtual environment, the system python won't see installed modules on it for example and vice-versa), but I don't know how his installation works at all so that might be normal.

It's probably me screwing up the installation, lol. I'm really trying to understand Python and the virtual environments like venv and pyenv, but I'm just not great at this stuff.

Edit: I'm up and running!

Oops, I mixed up the threads. Ijust posted this in the other thread:

Just a quick update, I just did a guide for using WhisperJAV:

WhisperJAV User Guide


The guide so far includes Windows, Mac, and Linux usage. It doesn't include the colab and kaggle releases. Those notebooks are basically implement the ensemble mode. The difference is that in Kaggle each pass is run in parallel on their dedicated GPU. In colab the two pass runs are orchestrated sequentially.

EDIT: I fixed it: For Mac users using Brew, you might need to run:
brew install portaudio
pip install pyaudio

Thanks. I added them to the install script and to the docs.
Again, I don't have a Mac to test, so just let me know if anything pops up.

I ran in "Balanced" mode, and it worked beautifully (if slowly, since it was CPU only-about 2 hours for a 2 hour video) The quality of translation is just really, really good-thank you for your hard work!

I'm now trying "Transformers" mode, which supports Metal, as I would like to give you some benchmarks between a MacMini M1 (Geekbench Metal 32K) and a MBP M1Pro (Geekbench Metal 68k)...it initially tried to just translate without Transcribing, but I think setting both the initial Transcription tab and Ensemble tab to Transformers mode has fixed it-running tests on both machines.

Thanks that would be helpful.
Meanwhile, give a try to ensemble mode 2-pass. You will like the results

I'll be sure to give them all a workout!

I'm seeing this error in the logs (on both Macs), but it still seems to run-is it not that important?

/Users/Toast/venvs/whisperjav/lib/python3.12/site-packages/requests/__init__.py:113: RequestsDependencyWarning: urllib3 (2.6.3) or chardet (7.0.1)/charset_normalizer (3.4.4) doesn't match a supported version!

Yes, that is a harmless dependency version warning

Sorry for all the Mac questions!
I am trying the Metal-enabled Transformers mode:

Device set to use cpu

Based on MacOS Activity Monitor, Transformers mode is using only CPU, no GPU cycles.
I have used your new guide to check, and my machine is seen as MPS, arm64, and I updated PyTorch to confirm they were default and not CUDA.
is there anything else I can do to force HuggingFace Transformers mode to use MPS?

Edit: I do not believe the CPU mode worked; the .SRT file was 0 bytes:

Whisper did not predict an ending timestamp, which can happen if audio is cut off in the middle of a word. Also make sure WhisperTimeStampLogitsProcessor was used during generation.
2026-03-06 14:22:21 - whisperjav - WARNING - Translation mode was requested but output appears to be in Japanese (14437/17022 chars are Japanese). This may indicate HuggingFace translation is not working as expected.
