The Teleprompter for Video app gives you the option to automatically add subtitles to your videos after recording. This post shows you how to add subtitles as well as some tips to ensure they are perfectly aligned to your speech.
First, you must record your video.
After recording, you will be taken to the preview screen where you can choose to Save, Share or Edit your video.
Tap the Add Subtitles button and you will be presented with some options to set the appearance of the subtitles. You can choose:
As you change these options, you will immediately see the subtitles previewed on the screen.
When you are happy with them, tap Done to return to the Save/Share screen.
If you Save/Share the video after adding subtitles then the video will take a little time to process while it is burning the subtitles into the video. Please do not close down the app while this is processing.
An .srt file is a file which contains text and timing information about subtitles. It is a standard format which can be imported into most video platforms such as YouTube, Facebook, Vimeo, LinkedIn. When you import subtitles using these platforms, the subtitles are displayed on top of your video, depending on the preferences of the user.
If you are unsure whether you want the subtitles or not, the best option is to Save the video without subtitles and export the subtitles as an .srt file. This then gives you the flexibility to add the subtitles later, and change them if needed.
If you have added subtitles to your video but wish to remove them, you can do so by tapping the Remove button at the bottom of the Add Subtitles page.
Tips for perfect subtitle timing
1. Use the guide
The timing of the subtitles is based on when the script scrolls near the camera. Therefore, to ensure your captions are well-timed to your voice, always try to read the script when it is in the guide area next to the camera lens (in the middle of the screen when recording landscape, or at the top of the screen when recording portrait).
To turn on the guide, go to the Settings menu (in the app) > Text area settings > GUIDE
2. Split your script into short sentences
Make sure to arrange your text into sentences. The app splits your script into sentences and then sets the timings based on when the sentence scrolls through the guide area. Try to avoid long sentences which the app has to split into multiple subtitles.
3. Allow countdowns to finish
If you use countdowns to pre-roll the script or end the recording, allow them to finish. The subtitles take this into account when calculating the timings so if you stop a countdown early this will impact your subtitle timings.
4. Use a mid-sized font
Using a mid-sized font eg. 30pt will help to ensure you can easily read the words whilst keeping them in the black area.
5. Add line breaks for pauses
Using line breaks can be a good way to pause between sentences.
Practice and have fun.
You may not get a perfect result the first time but after a few tries, you will be pleased with how much time this feature can save you.
