How to Add Subtitles to Your Videos (Free Guide)

Adding subtitles used to mean either paying a captioning service or spending hours manually syncing text to timecodes. Neither option was great. Today, AI can generate accurate subtitle files in minutes — and the whole process from upload to finished SRT file takes less time than it used to take just to find a captioning vendor.

Here's a practical guide to getting subtitles onto your videos, from generating the file to importing it into your editor or platform.

Why Subtitles Are Worth the Effort

Before the how-to, it's worth being clear on why subtitles matter — because the reasons go beyond just accessibility.

Accessibility. Deaf and hard-of-hearing viewers can't access your content without captions. This is the most important reason, and in many contexts it's a legal requirement.

Sound-off viewing. Feeds on Facebook, Instagram, LinkedIn, and TikTok often start videos muted, and plenty of people watch on a train or in an office with the sound off. Captions let them follow along instead of scrolling past.

Reuse. The same transcript that produces your subtitle file gives you text for a description, a blog post, or show notes.

Step 1: Generate Subtitles with PodText

The fastest way to get a subtitle file is to use PodText's video-to-text tool. Upload an MP4, MOV, or WebM file (up to 500 MB and 6 hours) or paste a direct link to a video file, and PodText transcribes the audio into timestamped passages you can export as subtitles.

Here's the process:

1. Go to PodText and upload your video or paste a direct media link.
2. Leave language detection on, or pick the language yourself if the video mixes languages.
3. Wait for processing; a progress view shows where the job is.
4. Review the transcript, especially proper nouns and brand names. Click a passage to hear the original. PodText doesn't edit text in the app, so correct anything in the exported SRT or VTT file before you import it into your video editor.
5. Export as SRT or VTT depending on where you're using the file.

For a video already on YouTube with captions, YouTube to text imports those captions instead.

SRT is the most widely supported format. VTT is the format HTML5 video players read natively, and some tools accept only VTT. When in doubt, export both. SRT vs VTT covers the differences.

Step 2: Import into Your Video Editor

Once you have the SRT or VTT file, importing it into your editor is straightforward.

Adobe Premiere Pro

Import the SRT file and add it to your sequence, and Premiere creates a captions track in the timeline. You can then style the captions in the captions panel: adjust font, size, position, and color to match your brand. For social media exports, consider burning the captions into the video (open captions) rather than keeping them as a separate track.

Final Cut Pro

In Final Cut Pro, choose File → Import → Captions and select your SRT file. Final Cut imports SRT, iTT, and CEA-608 (.scc) caption files, but not VTT, so use the SRT export here (Apple Support). Use the Inspector to adjust styling.

DaVinci Resolve

Choose File → Import → Subtitle, select your SRT file, then drag it from the Media Pool onto the timeline. Resolve has solid caption styling options in the Inspector. For YouTube exports, keep captions as a separate track so viewers can toggle them on and off.

Step 3: Upload to Platforms

Most major platforms let you upload subtitle files directly, which is better than burning them in — it gives viewers the option to turn captions on or off.

YouTube

In YouTube Studio, open your video, go to Subtitles, and click Add. Choose Upload file and select your SRT or VTT file; YouTube accepts both, along with several other formats (YouTube Help). Review the captions in the editor before publishing. A file you've reviewed is usually cleaner than an unreviewed auto-generated track.

Vimeo

Open the video's settings, find the subtitles and captions section, upload your file, and set the language. Vimeo accepts WebVTT, SRT, and a few other formats, and recommends WebVTT (Vimeo Help). You can add tracks in several languages.

Facebook

Facebook takes SRT files, and the file name must include the language and country code, such as my_video.en_US.srt, or the upload is rejected (Facebook Help).

Tips for Social Media Videos

Social media is where subtitles have the biggest impact, but the approach is a bit different.

Burn them in. For Instagram Reels, TikTok, and Facebook, burn the captions directly into the video rather than uploading a separate file. This ensures they display correctly across all devices and apps, and they'll show up even when the video is shared or embedded elsewhere.

Keep them short. Social captions work best with 1–2 lines of text at a time. If your SRT file has long lines, edit them down before burning in.

Style matters. Bold, high-contrast text with a subtle background or outline reads well on mobile. Avoid thin fonts or low-contrast color combinations.

Position carefully. Keep captions in the lower third but above any platform UI elements (like TikTok's caption area or Instagram's username overlay).

Getting subtitles right pays off every time you publish. Start with PodText's video transcription tool to generate your first subtitle file; your first 60 minutes are free.
