It looks like you’re having trouble getting MCEBuddy to extract VobSub subtitles from your MKV file and convert them to an SRT format, even with the OCR add-on installed. The log shows that MKVExtract is able to create an IDX file, but then MCEBuddy reports a FileNotFoundException for a .tmp file and ends up deleting an “empty subtitle file.”
VobSub subtitles are image-based, so OCR is indeed necessary to convert them into text-based SRT files. The FileNotFoundException and the “Empty Subtitle file” message suggest that either the OCR process isn’t successfully creating the temporary file or there’s an issue with MCEBuddy reading or processing it.
Let’s try to troubleshoot this.
First, could you confirm a few things:
OCR Add-on Installation: You mentioned you installed the OCR add-on. Can you confirm which OCR add-on you installed (e.g., specific version or where you downloaded it from)? Sometimes there can be different versions or configurations.
MCEBuddy Version: What version of MCEBuddy are you currently using? This information is usually at the top of your conversion log.
Subtitle Track Selection: In your MCEBuddy conversion task, under the “Subtitles” tab, have you selected “Extract Closed Captions/Subtitles”? And also, under “Subtitle Language (OCR),” is the correct language (e.g., English) selected for OCR processing?
In the meantime, let’s look for similar issues or solutions on the forum. I’ll search for “VobSub” and “OCR” to see if other users have encountered this.
Hi Joe,
It looks like you’re encountering a common issue when trying to extract VobSub (DVD) subtitles as SRT files with MCEBuddy. The log indicates that MCEBuddy is detecting the VobSub track and attempting to create an index file, but then it’s failing to find a temporary file, leading to an “Empty Subtitle file” warning and deletion. This suggests an issue with the OCR (Optical Character Recognition) process that’s needed to convert VobSub images into readable text for SRT.
Since you’ve already installed the OCR add-on, let’s explore a few possibilities:
OCR Engine Issues: Sometimes, the OCR engine might struggle with the specific font or quality of the VobSub images.
Permissions: Ensure MCEBuddy has full read/write permissions to the C:\\Program Files\\MCEBuddy2x\\working0\\ directory.
Temporary File Deletion: It’s possible an antivirus or other system process is prematurely deleting the temporary file that MCEBuddy creates during the OCR process.
Corrupt VobSub Track: While less common, a corrupt VobSub track in the MKV could cause issues during extraction and OCR.
To help diagnose this further, could you try the following:
Try another MKV file with VobSub subtitles (if you have one): This would help determine if the issue is specific to your “Twilight” file or a more general problem with VobSub OCR.
Manually extract the VobSub track: You can use a tool like MKVExtractGUI (a graphical interface for MKVToolNix) to manually extract the VobSub track from your MKV file as an .idx and .sub pair. Then, you can try using a standalone OCR tool (like SubRip) to convert those into an SRT to see if the VobSub data itself is parsable. This would help isolate if the problem is with MCEBuddy’s internal OCR process or the subtitle data itself.
Check MCEBuddy’s OCR settings: Double-check your MCEBuddy settings related to subtitles and OCR. Make sure OCR is explicitly enabled for VobSub tracks if there’s a specific option for it.
