If the app crashes after subtitle recognition is complete, it is generally due to the following reasons

1. Insufficient video memory (VRAM). You may have used a large model from the "large" series. Please use a smaller model, such as "small" or "medium".

2. If the app still crashes after switching to a smaller model, please check if the video file is very large (e.g., several hundred MB or even over 1 GB). In this case, you need to use an even smaller model and change the recognition mode to "Pre-split" or "Equal Split".

Additionally, you need to modify the beam_size and best_of settings in the menu: Tools -> Options. Change their values from 5 to 1.

3. cuDNN is not installed. For "faster" mode, installing only CUDA is insufficient. You also need to install cuDNN and cuBLAS separately. Otherwise, the app may crash or report an error like "cublasxxx.dll is missing".

Download the appropriate file from the links below, then copy the DLL files inside to either the C:/Windows/System32 directory or the software's root directory (where the .exe file is located).

Open a Command Prompt window (type cmd in any folder's address bar) and enter the command nvcc -V to check your current CUDA version.
