How to Generate Filmora Subtitles Automatically

Filmora’s built-in subtitle tools are helpful. But if you’re working on longer videos, need subtitles in multiple languages, or want more editing power — they can quickly feel limited.

That’s where Checksub comes in.

Step 1: Generate Subtitles

Go to checksub.com and sign in (or create a free account).

Click “Upload Video” and choose the file you want to subtitle. Checksub supports all major formats, so there’s no need to convert anything before uploading.

Once uploaded, select the original language of the video. Want to translate subtitles into more languages? You can do that too — right from the dashboard.

After the upload, Checksub’s AI gets to work:

• It transcribes the audio with high accuracy
• Breaks down speech into subtitle-length lines
• Syncs each caption with the video timeline

This process takes just a few minutes, even for longer videos.

No manual typing. No complicated tools. It’s all done for you.

Step 2: Edit and Review Your Subtitles

Once your subtitles are generated, you can review and clean them up using Checksub’s intuitive editor.

You can:

• Fix any minor transcription errors
• Adjust timing for faster or slower speech
• Add speaker labels or sound cues
• Keep line lengths short and mobile-friendly

The live preview makes it easy to see exactly how each subtitle will appear during playback.

Step 3: Export Subtitles

When your subtitles are ready, click Export and choose .srt as your file format.

Checksub will generate a clean, well-timed .srt file that’s fully compatible with Filmora. Just make sure you save it with UTF-8 encoding (default in Checksub) to avoid formatting issues.
