Why Use Captions for Instagram Posts?

The captions you use can make or break your social media success. An example of a caption that may result in you asking who unfollowed you again on Instagram is a one-liner quote irrelevant to your posted media. That does not elicit the interaction you need to go viral on the platform. So, what makes an Instagram photo or video caption good?

A good photo or video caption is written like an essay but on a smaller scale. It should have an introduction or catchy statement, body text, and a closing statement. The said parts of your text should only be two to three sentences at most to ensure you don’t lose your followers’ attention. The body should contain important information if you are promoting a product or a destination. Meanwhile, your closing statement or conclusion should include a call to action or even a question asking for opinions or suggestions. That will make it clear that you are communicating with your followers and encouraging audience engagement.

Additionally, do not forget to incorporate hashtags after your message. Hashtags are great in-app tools to help Instagram catalog your post and find the right audience for it.

Have you noticed that Instagram has gone beyond being a photo-sharing app? In the latest version of the platform, you can upload mini vlogs through IGTV and Instagram Stories. As an influencer, having more means to convey your message to your followers is important. That is why subtitles for video content are as helpful as photo captions. Subtitles are like captions but the words generated are exactly the words you are saying on the video. Adding subtitles seem to be less complicated than making captions, but it can be easier — thanks to tools dedicated to making those.

Kapwing is among the top platforms that can auto-generate closed-caption subtitles for your Instagram Stories or IGTV posts. It lets you instantly get your finished output straight from your Android or iOS devices. Simply upload your videos and the online application will automatically yield some captions for you. You may then make some alterations if the auto-generated caption is misspelled or wrong. Also, you are allowed to adjust the font style, size, and color to customize the appearance of the text on the video.

Since 2019, watermarks have already been removed on the outputs of users utilizing the free version of the tool. That is great. But if you want to expand your online video-editing workspace, you can go for Kapwing’s pro version.

Clips is a pre-installed video editor on Apple devices. It is probably one of the easiest apps to use if you want to auto-generate a caption for your Instagram videos.

Next, select the callout icon to open your captions menu. Set how the captions should appear on the screen before tapping the display. Lastly, long press on the red button to record the video the captions should be placed on.

Note that the caption tool in Clips can only be used when recording a live track. That means the tool is inaccessible on pre-recorded videos, so make sure to use the app when you want captions on videos you are just about to make.

Threads is another decent and effective Instagram caption generator to use when you want to add captions or subtitles for your Instagram Stories and IGTV posts. In a way, it is similar to Clips. However, the Threads app allows you to generate captions for pre-recorded videos in your camera roll. On top of that, you can also change any word that may come out incorrectly as a result of the auto-generated text. That is a huge plus considering you do not want your caption and video to be out of sync.

A bonus feature users might enjoy when using Threads is the video and message chat with other Instagram users regardless if they are on Threads or not.
