How to Add Subtitles to Downloaded Videos: A Comprehensive Guide
Adding subtitles to downloaded videos can significantly enhance your viewing experience. Whether you’re watching foreign films, have difficulty hearing, or simply prefer reading along, subtitles can make a world of difference. This comprehensive guide will walk you through various methods for adding subtitles to your downloaded videos, ensuring you never miss a word.
## Why Add Subtitles?
Before we dive into the ‘how,’ let’s briefly cover the ‘why.’ Subtitles offer numerous benefits:
* **Accessibility:** They make videos accessible to individuals who are deaf or hard of hearing.
* **Language Learning:** Subtitles can be a valuable tool for language learners, helping them improve their comprehension and vocabulary.
* **Clarity:** Sometimes, dialogue can be difficult to understand due to background noise, accents, or poor audio quality. Subtitles provide clarity and ensure you don’t miss crucial information.
* **Foreign Films & TV Shows:** Subtitles are essential for understanding content in languages you don’t speak.
* **Improved Focus:** Some people find that reading subtitles helps them stay more engaged and focused on the video content.
## Understanding Subtitle Formats
Before you start adding subtitles, it’s essential to understand the different subtitle file formats. The most common formats include:
* **SRT (SubRip Subtitle):** This is the most widely used and simplest format. SRT files are plain text files that contain the subtitle text along with the start and end times for each line.
* **ASS/SSA (Advanced SubStation Alpha/SubStation Alpha):** These formats are more advanced than SRT and allow for greater customization of subtitle appearance, including fonts, colors, and positioning.
* **SUB (MicroDVD Subtitle):** This format is less common than SRT but still used in some cases. SUB files typically contain timing information and subtitle text.
* **VTT (WebVTT):** A text format for displaying timed text tracks (such as subtitles or captions) using the Timed Text Markup Language (TTML). It’s designed for use with HTML5 video.
Knowing the format of your subtitle file is important because some video players and software may only support certain formats.
## Methods for Adding Subtitles to Downloaded Videos
There are several methods for adding subtitles to your downloaded videos, each with its own advantages and disadvantages. We’ll cover the most popular and effective techniques.
### 1. Using VLC Media Player
VLC Media Player is a free, open-source media player that supports a wide range of video and audio formats. It also has built-in subtitle support, making it a convenient option for adding subtitles to your videos.
**Steps:**
1. **Download and Install VLC Media Player:** If you don’t already have it, download VLC Media Player from the official website ([https://www.videolan.org/vlc/](https://www.videolan.org/vlc/)) and install it on your computer.
2. **Open the Video in VLC:** Launch VLC Media Player and open the video file you want to add subtitles to. You can do this by dragging and dropping the video file into the VLC window or by going to `Media > Open File` and selecting the video file.
3. **Add the Subtitle File:**
* **Method 1: Drag and Drop:** The easiest way is to simply drag and drop the subtitle file (e.g., `.srt`, `.ass`) into the VLC window while the video is playing. VLC should automatically recognize the subtitle file and display the subtitles.
* **Method 2: Using the Menu:** Alternatively, you can add the subtitle file through the menu. Go to `Subtitle > Add Subtitle File…` and select the subtitle file from your computer.
4. **Adjust Subtitle Settings (Optional):** VLC allows you to customize the appearance and timing of the subtitles. To access these settings, go to `Tools > Preferences`. In the Preferences window, click on `Subtitle / OSD`.
* **Subtitle Track:** Select the correct subtitle track if you have multiple subtitle files.
* **Subtitle Encoding:** Choose the correct encoding for the subtitle file. If you’re seeing strange characters, try changing the encoding to `UTF-8` or `Windows-1252`.
* **Font:** Change the font, size, and color of the subtitles.
* **Outline effect:** Add outline to the letters to make them stand out more.
* **Position:** Adjust the vertical position of the subtitles on the screen.
* **Subtitle Effect:** You can select a specific effect for your subtitles such as border size or shadow.
5. **Adjust Subtitle Delay (If Necessary):** If the subtitles are not synchronized with the audio, you can adjust the subtitle delay. Use the `H` and `G` keys to adjust subtitle delay on the fly (or access the option in `Tools > Track Synchronization > Subtitle track synchronization`). Pressing `H` will delay the subtitles, while pressing `G` will make them appear earlier. You can also adjust the delay in milliseconds in the `Track Synchronization` tab within the `Tools` menu.
6. **Enjoy Your Video with Subtitles:** Once you’ve added the subtitles and adjusted the settings to your liking, you can enjoy your video with subtitles.
**Pros:**
* Free and open-source.
* Supports a wide range of video and subtitle formats.
* Easy to use.
* Offers customization options for subtitle appearance and timing.
**Cons:**
* Subtitles are only displayed while playing the video in VLC. The changes are not permanent.
* Requires manual adjustment of subtitle delay in some cases.
### 2. Hardcoding Subtitles (Permanent Subtitles)
Hardcoding subtitles, also known as burning in or embedding subtitles, permanently adds the subtitles to the video file. This means that the subtitles will always be displayed, regardless of the media player you use.
**Warning:** This process modifies the video file itself, potentially reducing the video quality and requires a re-encoding of the whole video which can be time consuming. It is highly suggested that you create a backup copy of your video file before proceeding.
**Tools Required:**
* **HandBrake:** A free and open-source video transcoder ([https://handbrake.fr/](https://handbrake.fr/)).
**Steps:**
1. **Download and Install HandBrake:** Download HandBrake from the official website and install it on your computer.
2. **Open the Video in HandBrake:** Launch HandBrake and open the video file you want to add subtitles to. You can do this by clicking on `Open Source` and selecting the video file.
3. **Select the Subtitle Track:**
* Go to the `Subtitles` tab in HandBrake.
* Click on the `Track` dropdown menu and select `Add External SRT…` (or the appropriate option for your subtitle file format).
* Select the subtitle file from your computer.
* Make sure the `Burned In` checkbox is selected. This tells HandBrake to hardcode the subtitles into the video.
4. **Configure Output Settings:**
* In the `Summary` tab, choose your desired output format (e.g., MP4, MKV).
* In the `Video` tab, adjust the video settings as needed. You can choose the video codec, frame rate, and bitrate. Keep in mind that changing these settings can affect the video quality and file size. If quality is your biggest concern, set the ‘Quality’ setting to ‘Same as source’ in the video tab. This will keep the original quality to as high of a degree as possible.
* It is highly recommended to select ‘Constant Quality’ and setting the RF (Rate Factor) to around 18-22 to prevent massive file size increase and maintain good quality.
* **Important:** Be mindful of the resolution and encoding format. Ensure that you’re not upscaling to avoid unnecessary increases in file size with minimal quality improvement. Also, avoid using older or less efficient codecs unless there’s a specific compatibility requirement.
5. **Start Encoding:** Click on the `Start Encode` button to begin the encoding process. HandBrake will convert the video and hardcode the subtitles into the output file. The encoding time will depend on the size of the video and the processing power of your computer.
6. **Verify the Output:** Once the encoding is complete, open the output file in a media player to verify that the subtitles are displayed correctly.
**Pros:**
* Subtitles are permanently embedded in the video file.
* Subtitles will be displayed on any media player that supports the video format.
**Cons:**
* This process modifies the video file itself and requires a re-encoding of the whole video, potentially reducing the video quality.
* Subtitles cannot be turned off or customized once they are hardcoded.
* The encoding process can be time-consuming.
### 3. Muxing Subtitles (Soft Subtitles)
Muxing subtitles, also known as softsubbing, adds the subtitle file as a separate track within the video file container (e.g., MKV). This allows you to enable or disable the subtitles as needed, similar to how you would select a different audio track. Unlike hardcoding, muxing doesn’t alter the video stream; it only modifies the container.
**Tools Required:**
* **MKVToolNix:** A set of tools for creating, altering, and inspecting MKV files ([https://mkvtoolnix.download/](https://mkvtoolnix.download/)).
**Steps:**
1. **Download and Install MKVToolNix:** Download MKVToolNix from the official website and install it on your computer.
2. **Open MKVToolNix GUI:** Launch the MKVToolNix GUI (mkvmerge GUI).
3. **Add the Video and Subtitle Files:**
* Drag and drop the video file and the subtitle file into the `Input files` section of the MKVToolNix GUI.
* Alternatively, you can click on the `add input files` button and select the video and subtitle files from your computer.
4. **Configure Track Settings:**
* In the `Tracks, chapters and tags` section, you’ll see the video track and the subtitle track.
* Select the subtitle track and configure its settings:
* **Track name:** Give the subtitle track a descriptive name (e.g., “English Subtitles”).
* **Language:** Set the language of the subtitles.
* **Default track flag:** You can set the subtitle track as the default track, so it will be enabled by default when the video is played.
* **Forced display flag:** Use this option if the subtitles only contain translated parts of the video and are only supposed to be displayed when the original language is not understandable (e.g. the alien speaks an alien language that needs to be translated).
5. **Specify Output File:**
* In the `Output filename` section, specify the name and location of the output MKV file.
6. **Start Muxing:** Click on the `Start muxing` button to begin the muxing process. MKVToolNix will add the subtitle file to the video file container.
7. **Verify the Output:** Once the muxing is complete, open the output MKV file in a media player that supports MKV files and soft subtitles (e.g., VLC Media Player, MPC-HC). You should be able to enable or disable the subtitles as needed.
**Pros:**
* Does not alter the video stream, preserving the original video quality.
* Subtitles can be enabled or disabled as needed.
* The muxing process is relatively fast.
**Cons:**
* Only works with video containers that support multiple tracks (e.g., MKV).
* Requires a media player that supports soft subtitles.
### 4. Online Subtitle Editors
Several online subtitle editors allow you to create, edit, and synchronize subtitles directly in your web browser. These tools can be useful if you need to correct errors in existing subtitle files or create subtitles from scratch.
**Popular Online Subtitle Editors:**
* **Subtitle Edit Online:** A web-based version of the popular Subtitle Edit software ([https://www.nikse.dk/SubtitleEdit/Online](https://www.nikse.dk/SubtitleEdit/Online)).
* **VEED.IO Subtitle Editor:** VEED.IO offers a user-friendly online subtitle editor with features like automatic transcription and translation ([https://www.veed.io/tools/subtitle-editor](https://www.veed.io/tools/subtitle-editor)).

**Tips for Finding the Right Subtitle File:**
* **Match the Release:** Make sure the subtitle file is specifically designed for the version of the video you have. Different releases may have slightly different timings, which can cause synchronization issues.
* **Check the Frame Rate:** The frame rate of the subtitle file should match the frame rate of the video. Common frame rates include 23.976 fps, 24 fps, 25 fps, 29.97 fps, and 30 fps.
* **Read User Reviews:** Check the user reviews or ratings of the subtitle file to get an idea of its quality and accuracy.
## Troubleshooting Subtitle Issues
Even with the best methods, you may encounter issues with subtitles. Here are some common problems and how to fix them:
* **Subtitles Not Showing:**
* Make sure the subtitle file is in the same folder as the video file and has the same name (except for the extension).
* Verify that your media player supports the subtitle format.
* Check that subtitles are enabled in your media player settings.
* **Subtitles Out of Sync:**
* Adjust the subtitle delay in your media player settings (as described earlier for VLC Media Player).
* Use an online subtitle editor to manually adjust the timing of the subtitles.
* Search for a different subtitle file that is specifically designed for your video release.
* **Strange Characters in Subtitles:**
* Change the subtitle encoding in your media player settings (as described earlier for VLC Media Player). Common encodings include UTF-8, Windows-1252, and ISO-8859-1.
* **Subtitles Too Small or Too Large:**
* Adjust the font size in your media player settings.
* Use an online subtitle editor to change the font size in the subtitle file.
* **Subtitles Overlapping:**
* This can happen in .ASS or .SSA files when styling is not correctly set. Edit the file in a text editor, if you are familiar with the format or try to find another version of the file.
* **Subtitles cover the entire screen:**
* This is also common in .ASS or .SSA files. Look for lines like `{\an8}` which force the text position. Remove these or adjust the numbers to correct it.
