Chinese video and subtitle filename checker

A free Chinese-language helper for comparing video and subtitle filenames before asking for playback support. Enter a video filename and a subtitle filename to compare their basenames and extensions. The page includes a filename checklist and a support-record template. It works on typed filenames only: it does not upload files, read file contents, repair subtitles, or prove player compatibility. Use the result to prepare a clearer support question, then test your actual files in your player. Created and maintained by the Yuanqiao resource-notes project with AI assistance.
