Add Automatic Subtitles to Your Videos
Generate Subtitles From Speech
Flixier recognizes the speech in your video or audio and turns it into timed subtitles. Once they appear on the timeline, play the back recording to check the text against what each person says.
Correct Text and Timing
Use Flixier’s online subtitle editor to fix names, technical terms, or other transcription mistakes. You can also change when each subtitle appears and how long it remains on screen.
Customize Your Subtitles
Choose a subtitle preset or adjust the font, size, color, background, and position yourself. Preview the video as you work to make sure the captions remain easy to read without covering important details.
Translate Your Captions
Translate your subtitles to another language using the subtitles you generated. Review the translated text, make any necessary corrections, and download the new subtitle file or add it to your video.

Why Use Flixier to Generate Subtitles
Edit the Video and Captions Together
Cut unwanted sections, add images, music, or motion graphics, and update the subtitles in the same project. When you remove part of the recording, you can also adjust the surrounding captions before exporting.
Generate Subtitles From Any Video or Audio
Create subtitles from common video and audio formats, including MP4, MOV, AVI, MKV, WebM, MP3, WAV, and AAC. Flixier turns the spoken audio into timed text that you can review and correct alongside the original recording.
Save Subtitles in Different Formats
Add subtitles to your video or download them separately as SRT, VTT, TXT, STL, or SUB files, so you have access to all the most popular formats for YouTube, socials, or personal projects.
Keep Your Subtitle Style Consistent
Customize the font, colors, size, and overall look of your subtitles, then save the style to your Brand Kit. Apply it to future videos without recreating the same design each time.

What is an AI subtitle generator?
An AI subtitle generator recognizes the speech in a video or audio recording and turns it into timed text. Flixier places the generated subtitles on your timeline, where you can correct the wording, change their timing, customize their appearance, and include them in the finished video.
How do I generate subtitles automatically?
Import your video or audio into Flixier and add it to the timeline. Right-click the clip, select Generate Subtitle, and choose the language spoken in the recording. Once the subtitles are ready, play the project to check the text and timing before exporting.
Can I edit AI-generated subtitles?
Yes, you can correct words, rewrite individual lines, and adjust when each subtitle appears or disappears. Flixier also lets you change the font, size, color, background, and position, so the captions match the video and remain readable.
Can I translate the subtitles after generating them?
Sure, after generating and reviewing the original subtitles, you can translate them into another language inside Flixier. Check the translated text for names, specialist terms, or phrases that may need correcting, then export the translated video or download the subtitle track.
Is Flixier’s AI subtitle generator free?
Flixier’s Free plan currently includes up to five minutes of AI-generated subtitles. You can use those minutes to test subtitle generation, correct the resulting text, customize its appearance, and export a short, captioned video before deciding whether to upgrade.
