How to Caption Your Slack Video Meeting Recordings in 4 Steps

If you use Slack a lot for work, you may be going into video meetings frequently with your team on the platform. These may contain vital information that you need to relay to your team members. One way to keep your team posted is to send a captioned video recording of the meeting – but how exactly do you make Slack video meeting captions? Here are 4 simple steps.

1. Record the video meeting

Currently, Slack lacks a built-in recording feature for its video meetings, but there are two workarounds you can choose from:

Third-party recording tool

There are a few free desktop recording programs available such as:

  • Free Cam
  • OBS Studio
  • Bandicam (10 minutes only for the free version)

Keep in mind that most programs record your entire desktop, so they will also capture any actions you make (such as switching between programs). This can be inconvenient if you want the entire recording to focus only on the meeting itself.

Video call platform integration

Slack has several integrations with third-party video calling programs, including:

  • Skype
  • Google Meet
  • Zoom

These apps often have a built-in meeting recording feature, making them an excellent alternative if you want to record your meetings.

2. Transcribe the recording

Transcribing your video makes it easier to add your captions later, as you only have to copy and paste each line of text at the correct times.

Here is a simple process of how to transcribe your video recording:

  1. Open the word processor of your choice
  2. Open the video file with your preferred media player
  3. Place the two programs beside each other. Use app split-screen functionality so you can quickly switch between the two when needed (e.g. rewinding the clip).
  4. Play the recording and type down each line of dialogue. Indicate who says each utterance (and at what time in the video, for best effect)
  5. Replay the entire recording and correct any mistakes that you made in transcription.

Making video transcriptions is tedious and time-consuming. Consider using machine transcriptions so you can focus on other tasks.

3. Caption the video

After making the transcript of the recording, you will now edit the recording to include your transcription. This step mainly involves using a third-party video-editing program.

This is how you caption the video:

  1. Open the video editing software of your choice.
  2. Import the video file.
  3. Add your transcription line-by-line using the text tool. This is easier if you added timestamps while recording.
  4. Match each line to the proper times.

If you’ll share the captioned video to teammates in your organization, it’s best to make sure that the captioning is easily readable. This increases the accessibility and reusability of your recording for other purposes in the other feature.

Try these out to make your captions readable for any audience:

  • Adding a basic text outline 
  • Keeping the captions less than 6-7 words per line
  • Using a font size that is big enough and proportional to the video

4. Finalize and polish

It’s important to look over your work before rendering the final video to make sure that you covered all the bases. Consider the following when finalizing your video:

  • Did you place the captions at the right times?
  • Is the font size sufficient? Do I need to make certain fonts bigger/smaller?
  • Are the captions readable throughout the entire recording?
  • Did you crop the video just enough to focus only on the meeting?

Rendering settings are also vital, as these play an important role in the readability of your captions. For best effect, keep the same resolution as the original video to maintain video quality and make the font as sharp as possible.

Once you’re done rendering the video, share it with your team by uploading it on the cloud and sending them the link.

Captioning video meeting recordings can be counterproductive if it takes a lot of time away from your main tasks. Use an AI transcription service to caption your videos while you focus on your more important work.
