Crashing After Subtitle Recognition: Common Causes

Crashing after the subtitle recognition process completes can usually be attributed to a few key issues:

1. Insufficient VRAM (Video RAM). If you're using a large language model (LLM) from the "large" series, try switching to a smaller model, such as "small" or "medium."

2. Still Crashing with Small Models? Check if your video file is very large (e.g., hundreds of MB or even several GB). In this case, you should use an even smaller model and change the recognition mode to "pre-segmentation" or "equal segmentation."

Also, modify the beam_size and best_of settings in Menu - Tools - Options, changing them from 5 to 1.

3. Missing cuDNN Installation. If you're using "faster" mode, installing only CUDA is not sufficient. You also need to install cuDNN and cuBLAS. Otherwise, the application may crash or report an error such as "cublasxxx.dll missing".

Download the appropriate files below, and copy the DLL files within to C:/Windows/System32 or the application's root directory (where the .exe file is located).

Open a command prompt in any folder by typing cmd in the address bar. Then, type the command nvcc -V to check your current CUDA version.
