After you have inputted the title using all the tips above, flow is also an important aspect to consider. You will have to listen to the dialogue so as to type the corresponding text in each segment of the video. This is done rather simply. All you have to do is drag and drop the subtitle (title) to the frame that starts the dialogue you are working on. Next, you trim this title to come into incongruity with the end of the dialogue.
If the sound isn’t dialogue but is somehow meaningful to the video, you can put it in brackets within the subtitle.
In order to start your next clip, all you have to do is copy and paste your current subtitle to the new clip to start. This would help you retain the text style and save you the stress of having to start editing every time you begin a new clip.
Moving on, to prevent subtitles from staying on top of each other, you will see a play head. Move the play head to the part in the timeline where the title doesn’t exist.
After you have typed in all the subtitles and edited the fonts, style, and everything aligns with what you propose your subtitle to be, you can now share the file you have made. You can decide to send it as a file or send it into the iMovie theatre, Facebook, Vimeo, iTunes, or YouTube. There is a small share icon at the top right corner of the app. Click on it, then share the file.
The good thing is iMovie does not need or require any special setting for you to be able to export your videos with the open subtitles you have set since as a matter of fact, they are titles rendered onto the video.
Note, however, for the best experience, export at the best resolution, quality, and compression.
After you export the file, open it. Now, you would be able to see all your captions during playbacks.
