There are several common reasons for crashing after subtitle recognition is complete:

1. Insufficient video memory (VRAM). If you are using a large model from the "large" series, please try using a smaller model, such as "small" or "medium."

2. If you are still experiencing crashes even with a smaller model, check if the video is very large (e.g., hundreds of MB or even GB). In this case, you need to use an even smaller model and change the recognition mode to "pre-segmentation" or "equal segmentation."

Additionally, you need to modify beam_size and best_of in Menu-Tools-Options, changing them from 5 to 1.

3. cudnn is not installed. Using "faster" mode requires installing cudnn and cublas in addition to cuda. Otherwise, it will crash or report "cublasxxx.dll does not exist."

Download the following files and copy the DLL files inside to the C:/Windows/System32 directory or the software's root directory (the directory where the exe file is located).

Open a black window by typing cmd in the address bar of any folder, and enter the command nvcc -V to view the current CUDA version.
