Troubleshooting: App Crashes After Subtitle Recognition

Here are some common reasons why your application might crash after subtitle recognition is complete:

1. Insufficient VRAM (Video RAM). If you're using a large model from the large series, try using a smaller model like small or medium.

2. Still Crashing with Small Models? Check the video size. Large videos (hundreds of MBs or even GBs) require smaller models and a different recognition mode like "Pre-segmentation" or "Even Segmentation".

Also, adjust beam_size and best_of in Menu-Tools-Options from 5 to 1.

3. Missing cuDNN Installation. Using "faster" mode requires cuDNN and cuBLAS, in addition to CUDA. Simply installing CUDA is not enough. Without these, the application may crash or report "cublasxxx.dll missing."

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

To check your CUDA version, type cmd in the address bar of any folder to open a command prompt, and then enter the command nvcc -V.
