Part 2. How to Automatically Add Subtitles to Movies on Your Phone Using AI Caption
Now that you know all the cool features Filmora offers, let's dive into how to add subtitles to a downloaded movie on Android or iPhone. But before we get started, just a quick reminder: if you're downloading a movie to add subtitles, make sure you're not violating any copyright rules. It's always best to stick to legally downloaded content to avoid any trouble.
Now, let's jump into how you can easily add subtitles with Filmora to level up your movie-watching experience! As we mentioned earlier, the best way to do this is by using the Auto Caption tool. It automatically creates subtitles for you, making the whole process quick and effortless. Just follow this simple guide, and you'll be good to go!
Step 1. Open Filmora and access the AI Caption feature
First, download the Filmora Mobile app either on Google Play Store or Apple Store if you haven't already. Once it's installed, open the app and tap on the "AI Caption" option.

Alternatively, you can also access the AI Caption feature by clicking the three dots (...) button and selecting "AI Caption" in the next window that appears.

Step 2. Upload your movie
Next, find the movie you want to add subtitles to in your phone's library. Just select your clip, and then click "Import".

Step 3. Choose language and add captions
On the next screen, your video will play. Filmora's AI can detect the language automatically, but selecting the video’s language yourself improves accuracy. Then tap "Add Captions" to start subtitle creation.

Step 4. Choose subtitles style
When the AI finishes, choose a subtitle style from Filmora’s templates. Tap your favorite and preview it. If you want, click "Project Edit" to customize more, or tap "Export" to save immediately.

Step 5. Adjust subtitles position
Tapping "Project Edit" opens the main editor. You can drag subtitles anywhere, like the bottom of the screen, to avoid covering the video. For corrections or adjustments, use the "Batch Edit" option in the toolbar.

Step 6. Customize subtitles in batch edit
In batch edit, you can adjust subtitles freely. To combine two lines, tap "Merge above" or "Merge below." To split a long line, tap "Split." To delete a subtitle part, tap the trash can icon.

Step 7. Change subtitles style if necessary
Next, if you want to update the look of your subtitles, tap the "Style" option in the toolbar.

From there, you can change the font, size, and color, and even add some cool animations to your subtitles.

Step 8. Export your video
When you're done with all the edits, tap "Export" at the top right of the screen.

Then, choose your preferred resolution and frame rate, then tap "Export" again to save the video to your phone.

Part 3. How to Manually Add Subtitles to Movies on Your Phone
Now that you've learned how to automatically add subtitles to a movie permanently on Android and iPhone with Filmora's AI Caption tool, let's go over how to do it manually. As we mentioned before, Filmora also gives you the option to add subtitles yourself, and this can be super useful if you want more control over the timing, style, or content of your subtitles.
Here's a simple step-by-step guide to get started
Step 1. Open Filmora and start a new project
This time, once you open the Filmora mobile app on your phone, tap on "New Project" to get started with your editing.

Step 2. Select your video clips
Next, choose the movie you want to subtitle from your phone's library. Tap on "Video", select your clip, and then press "Import". Your video will be added to the editing timeline, ready for you to start making edits.

Step 3. Write subtitles manually
Once you're in the main editing screen, hit the "Text" option from the toolbar.

Then, select "Add" to start writing your subtitles.

Write the subtitles based on what you hear. Then, move the subtitles position to the bottom of the video so it doesn't block the movie.

Step 4. Edit subtitles
Next, you can customize the subtitles by changing the style, size, and font, and even adding some animations—just like you would in the batch edit window with the AI Caption tool. When you're happy with your changes, tap the checkmark button to save them.

Now that the subtitles are added to your video, you can adjust their timing using the trim feature shown in the picture below. You'll need to repeat this process to manually add each subtitle line. It might take a bit of time, but this way you can make sure everything is perfectly accurate!

After that, you can tap Export and save the video like before.
Bonus: Adding Subtitles on PC for Greater Flexibility
As you can see, adding subtitles to your movie on iPhone and Android is easy with the help of Filmora's powerful tools. However, if your movie is an hour or two long it can be tricky to edit that on a mobile phone. The small editing space and potential performance issues on your phone can make it tough to edit such big files. In this case, switching to a PC might be a better option.
Luckily, Filmora also has a desktop version that comes with advanced features like Speech-to-Text. Plus, the PC version is more powerful than the mobile app and offers even more editing tools.

Here's why Filmora for desktop is also worth trying out:
