Subtitles can boost viewer engagement and watch time, helping you stand out among content creators, marketers, vloggers, and other video professionals. Besides improving comprehension, they attract viewers who prefer watching videos without sound or must mute them at work or in public spaces. Subtitles also make your videos accessible, enabling the DHOH (Deaf and Hard of Hearing) community to enjoy them.
Filmora can help you add subtitles to your iPhone videos within seconds. It’s the best video editing software with audio and image editing features available on iOS, Android, Windows, and macOS. Download Filmora for iOS and follow the guide below as we show you how to add subtitles to a video on an iPhone for free.

A Step-by-Step Guide to Adding Subtitles to Videos on iPhone Devices
Filmora Mobile has a free version with limited functionalities like its desktop counterpart. AI features require AI credits either way, but you get 100 during a trial (you must create an account). Therefore, you can add subtitles and try other AI tools without paying.
Here’s how to add subtitles to a video on an iPhone using Filmora’s AI Captions feature:
Step 1: Launch the app and tap AI Captions.
Step 2: Choose a video and tap Import.
Step 3: Specify the video’s language and tap Add Captions. You can also choose another language under Bilingual Captions (we’ll show how to do that while editing) and customize the AI Packaging (AI Highlight, AI Emoji, AI Camera, and Smart Sticker). Additionally, you can enable Speaker Detection (if your video has more than one speaker).
Step 4: Choose a template for dynamic captions or tap None (the first option) for regular subtitles. Then, hit Export or Project Edit.
Step 5: Resize and reposition the text in the Player panel and tap AI Edit.
Step 6: Flip the switches to turn the AI features on or off. For instance, you can turn off AI Emoji and enable the AI Camera (if you haven’t already) to track the speaker’s frame or adjust the frame zoom according to their emotions.
Step 7: Go to Batch Edit to fine-tune the captions.
Step 8: Edit the text (if necessary) and merge or split the captions.
Step 9: Go to Highlight options.
Step 10: Edit highlight words, including their color, font, and size. You can also enrich them with sound effects and change active words by tapping them.
Step 11: Select Bilingual Captions to add subtitles in another language.
Step 12: Choose a language, tick the Apply to All Captions checkbox, and tap Translate.
Step 13: The subtitle alignment may not match your captions, so select the subtitle track and tap Style.
Step 14: Go to Align and adjust the subtitles according to your dynamic captions. For instance, set the Line Break to a Single Word and the Line number to one.
That’s how you add subtitles to videos on iPhone devices using Filmora’s AI Captions. You can transcribe and translate videos within seconds. If you wonder how to put subtitles in videos on Android with Filmora, you’ll be happy to know the process is identical.
Filmora’s Android and iOS apps are twins, so download Filmora for Android and follow this guide’s steps to add subtitles to videos. Then, proceed to the section below to fine-tune your subtitles because Filmora offers many more customizations.
Use Filmora’s Text Editing Features to Edit the Text Further
Filmora offers many features for editing text. You’ve seen some while changing the subtitle alignment in the example above. Let’s delve deeper into them to perfect your captions.
Here’s how to change the text template, style, font, art, emojis, and animation on Filmora Mobile:
Step 1: Select your subtitles on the timeline and tap Template, Style, Emoji, Animation, Font, or Art. The toolbar at the bottom has dedicated buttons for each. However, it doesn’t matter which you choose first because they all open in the same section. Let’s start with the Template option.
Step 2: Browse templates for dynamic captions and pick your favorite. Tap any to preview it; the original won’t change until you hit the Checkmark.
Step 3: Go to Style and change the text color, size, case, opacity, border, background, shadow, alignment, and position. You can apply the modifications to all captions by ticking the checkbox.
Step 4: Go to Font and browse hundreds of options. Choose an eye-catching yet legible one.
Step 5: Go to Art and pick a design ideal for your video’s vibe. You’ll find unique text art bound to engage your viewers.
Step 6: Go to Emoji and customize their timing and position (unless you turned them off).
Step 7: Go to Animation and change the Transition Target. However, you won’t see a difference with a single-word alignment. Here’s an example of a multi-word alignment on two lines: tap Line or Word to make the text appear line by line or word by word (respectively) or enable the Page option to display both lines instantly.
Step 8: Scroll down to the Active Word Target, Color, and Background to spice things up further.
Step 9: Tap Export to save your video after perfecting your subtitles and experimenting with other features.
Step 10: Choose the resolution and frame rate and hit Export.
