How to Add Subtitles to YouTube Videos

To add subtitles to a YouTube video, use YouTube Studio for a video that is already uploaded, or add captions to your local video before uploading it. ClipsPal helps with the local-file route: review the transcript, style subtitles, then export captions in the video or as an SRT file.

Add subtitles before or after uploading?

Choose the route based on where your video is now. If it is already on YouTube, manage its caption track in YouTube Studio. If you have the video file on your Mac and want text permanently visible in the picture, prepare and review the captions before uploading.

The formats work differently. Burned-in subtitles are part of the video image and stay visible wherever the video plays. An SRT file holds timed caption text separately; YouTube can use it to create a caption track. You can also add captions in Studio by typing them, syncing a transcript, or uploading a timed file, as described in YouTube's caption guide.

ClipsPal is a Mac video editor for the local-file workflow. It does not import a YouTube URL, edit a published upload, or upload or publish a video for you. For another way to prepare a YouTube video locally, see the YouTube clip maker.

Add subtitles to a local video before upload

In ClipsPal, import the video file from your computer and transcribe it. Choose Sentence or Word by word subtitle grouping, then read the transcript against the recording. Correct names, missed words, and punctuation before styling the subtitle track.

Export the version you need:

• Export a video with burned-in captions when the subtitles should always appear in the picture.
• Export an SRT when you want a separate timed caption file to upload as a YouTube track.

Watch the complete exported video before uploading. Check that each subtitle matches the speech and stays on screen long enough to read. ClipsPal supports subtitles in its editing workflow; see the ClipsPal guide for the current workflow.

Transcription creates a starting point, not a finished caption track. Review it carefully, especially names, specialized terms, and speech that overlaps. Fixing the text before export is easier than finding mistakes after the video is live.

Add captions to a video in YouTube Studio

For an uploaded video, sign in to YouTube Studio and open Subtitles from the left menu. Select the video, choose Add language, and select the language for the captions. Under Subtitles, choose Add and select the caption workflow.

To use an SRT, choose Upload file, select With timing, then upload the file and save. YouTube's guide also describes typing captions and entering a transcript for automatic syncing. Captions can be added during upload as well.

To change a caption track later, open the video under Subtitles, choose Edit for its language, and adjust the text or timestamps. Select Publish when the edits are ready. YouTube explains the caption editing steps.

Check subtitles before publishing

Play the full video with captions on, and check:

• Names: People, places, and product names are spelled correctly.
• Punctuation: Sentences read naturally and distinguish separate thoughts.
• Overlapping speech: Each speaker's words remain understandable when people talk at once.
• Timing: Captions appear with the speech and do not flash too quickly or linger after it ends.
• Mobile readability: Text is large enough to read and does not cover faces or important details on a small screen.

If you exported an SRT, check the track in YouTube Studio after uploading it. If captions are burned into the video, review them in the exported file because they are part of the picture rather than a separate YouTube track.
