VideoProc Converter AI is a powerful tool for managing video subtitles across various formats. It lets you add, remove, and customize subtitles while maintaining video quality, and download subtitle files from numerous websites. While users occasionally encounter issues with these features, most problems have straightforward solutions. In this article, we will guide you through common subtitle-related issues and their fixes, and also answer the frequently asked question: Does VideoProc Converter AI support batch adding subtitles.

Part 1. Understand Subtitles

Before jumping into solutions, it's important to grasp the basics of subtitles:

External Subtitles

External subtitles are separate files (e.g., SRT, ASS) that are loaded alongside the video during playback. The media player detects and syncs them with the video, allowing viewers to watch content with subtitles. These subtitles can be easily replaced, edited, or removed.

Hardcoded Subtitles

Hardcoded subtitles are permanently embedded into the video as part of the image. They cannot be removed, edited, or extracted because they are no longer text-based. These subtitles are visible during playback but cannot be altered.

Softcoded Subtitles

Softcoded subtitles, also known as internal or embedded subtitles, are included in the video file but remain separate from the video and audio tracks. Often found in MKV files, they can be turned on or off, extracted, edited, or removed with the right tools, offering flexibility but requiring more complex management.

Part 2. Identify the Subtitles Type in Your Video

You can use MediaInfo (https://mediaarea.net/en/MediaInfo) to identify subtitle types:

• 1. Download, install, and open MediaInfo. Load your video file.
• 2. Go to the Text section and check the Format column to check the subtitle format:
• • Text/SSA/ASS: External subtitles.
• • DVD/Blu-ray subtitles: Typically hardcoded.
• • SubRip/UTF-8: Soft subtitles embedded within the video file.

Part 3. Solutions to Common Subtitle Issues

Missing Subtitles During Video Conversion

This section addresses issues where subtitles are lost or encounter problems during video conversion.

Problem 1. Missing Subtitles

Problem description: "One thing though and I am not sure if VideoProc can do this but I am looking to convert H265 to H264 without losing the embedded subtitles, obviously an SRT file would still work. At this point the video and audio converts fine but all of the embedded subtitles disappear. Any thoughts?"

Cause 1: Disabled Subtitle Track

VideoProc Converter AI disables subtitle tracks by default.

Solution: Before starting the conversion, make sure to select the subtitle tracks you need. Here's how:

• 1. Navigate to the video's information bar.
• 2. Click the subtitles drop-down menu.
• 3. Choose the desired subtitle track.

Problem 2. No Separate Subtitle Track After Conversion

Problem description: You've selected subtitles before converting your video, but the output doesn't have a separate, selectable subtitle track.

Cause: You chose to hardcode the subtitles into the video. Hardcoded subtitles are embedded directly into the video and won't appear as a separate subtitle track.

Solution: When you play the video, the subtitles are visible, but you can't edit or extract them because they're part of the video image. If you want to have separate control over the subtitle track - to enable or disable subtitles during playback, or to edit them - you need to choose softcoded subtitles instead of hardcoded ones. How to select softcoded subtitles:

• 1. Go to subtitle settings in the video information bar.
• 2. Click on the H symbol next to the subtitle track to switch it to S, which stands for softcoded subtitles.

Problems When Adding Subtitles

This section helps resolve issues when adding subtitles to your videos using VideoProc Converter AI, such as import failures and subtitles being out of sync with the video.

Problem 1. Subtitle File Fails to Load

Cause: Incompatible subtitle format or encoding. VideoProc Converter AI supports SRT/ASS/SSA/SUB subtitles encoded in UTF-8.

Solution: Ensure your subtitle file has an extension of .srt, .ssa, .ass, or .sub. If the error still exists, verify and convert encoding to UTF-8:

• 1. Open the subtitle file in NotePad++.
• 2. Go to the top menu bar and select Encoding. Confirm if it's with UTF-8.
• 3. If not, choose Convert to UTF-8 and save the outcome.

Problem 2. Subtitles Out of Sync with Video

Cause: Problems within the subtitle file itself.

Solution: Double-check your subtitle file for errors. You may need to find a different or corrected subtitle file from your source.

Problem 3. Subtitle Search Fails

Cause: Incorrect search terms.

Solution: Use the precise title or file name of the video when searching for subtitles. For example, when looking for subtitles for "Dune: Part Two", enter exactly that. Do not use variations like "Dune: PartTwo"

Problem 4. Restricted Subtitle Access

Problem description: You're required a premium subscription to access the subtitles.

Cause: This is a limitation of the website, not VideoProc Converter AI.

Solution: You may need to consider a different subtitle source, or subscribe to the website's premium service to access the full subtitles.

Problems When Removing Subtitles

This section addresses issues related to removing subtitles using VideoProc Converter AI.

Problem. Failed to Eliminate Subtitles

Problem description: "I am trying to use VidoeProc ro delete embedded Subtitles. I can see them in the text section when using MediaInfo. However, I don'tly seem able to eliminate them from the MP4 so they will certainly show on my friend's TV which has no control over subtitles."

Cause 1: You've selected the subtitle track.

Solution: Before starting the conversion, ensure that Disable Subtitles is selected.

Cause 2: The subtitles are hardcoded (burned into the original video). Hardcoded subtitles are part of the video image and cannot be removed.

Solution: In this case, you will need to find a different video source without hardcoded subtitles.

Problems When Extracting Subtitles

This section covers problems related to extracting subtitles from videos.

Problem. Fail to Extract Subtitles

Problem description: "It extracted NOTHING for subtitles in an mp4 video! Hit run and it did nothing! Absolutely nothing! Nada! I was able to use a player to extract as sup but this app did NOTHING!"

Cause: The subtitles in the source video are hardcoded. As part of the video image, they cannot be extracted.

Solution: In this case, you need to switch to a video with softcoded subtitles, which are separate from the video stream and can be edited or extracted.

Subtitle Problems in Downloaded Videos

This section addresses issues where subtitle tracks are not found in downloaded videos.

Problem. No Subtitle Tracks Are Found

Problem Description: "when i download the video with a subtitle, the subtitle file are not downloaded."

Cause 1: CC subtitles (auto-generated).

Websites like YouTube and Vimeo provide automatically generated CC (closed captions) subtitles that cannot be downloaded.

Solution: Unfortunately, there's usually no solution to download these subtitles as they are real-time generated by the video platform.

Cause 2: The issue with the source video.

If the original video has subtitle tracks, but they are not downloaded, it might be an issue with the video itself or the specific video source.

Solution: Try downloading the video from another source or check if the video has embedded subtitle tracks. You can also try other videos from the same link or source.

Cause 3: It's hardcoded subtitles.

Some videos have hardcoded subtitles (embedded as images in the video).

Solution: Hardcoded subtitles are part of the video itself. These will display when playing the video but won't show as a separate subtitle track and cannot be edited.

Part 4. FAQ on Subtitle Bulk Management

Question Description: "I have a full folder of videos. Do I have to manually select each audio & subtitle option for each video i intend to convert."

Answear: When managing subtitle files for multiple videos, VideoProc Converter AI requires you to select the desired subtitle tracks for each video individually. This manual selection process ensures accuracy, especially when your videos have varying numbers of subtitle tracks.

While manual selection is necessary, the overall process is straightforward and efficient, as you can import multiple videos in bulk, select the desired subtitle tracks for each video, and then export them all together.
