Why Your App Crashes After Subtitle Recognition Completes: Common Reasons

1. Insufficient GPU memory. If you're using large models from the "large" series, please switch to smaller models such as "small" or "medium".

2. If the app still crashes even after using a smaller model, check if the video file is very large (e.g., hundreds of MB or even over 1 GB). In such cases, you should use an even smaller model and change the recognition mode to "Pre-segmentation" or "Equal Segmentation".

Additionally, you'll need to modify the beam_size and best_of settings in Menu > Tools > Options from 5 to 1.

3. CuDNN is not installed. For "faster" mode, simply installing CUDA is not enough; you also need to install CuDNN and CuBLAS. Otherwise, the application may crash or report an error like "cublasxxx.dll not found".

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

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