Do you know when captions were first added to videos?
Around five decades back - to help hard of hearing and deaf viewers.
Fast forward to today, captioning has evolved significantly with advancing technology. From making its place on television to becoming a vital accessibility component on streaming services, captioning technology has applications in many sectors.
Besides, captions help a viewer better define words, comprehend and retain information, identify emotions, and draw conclusions from videos. At present, adding captions has become a necessity with guidelines like the Americans with Disabilities Act (ADA) and Web Content Accessibility Guidelines (WCAG).
However, a 2020 report says that 98.1% of home pages have at least a single WCAG 2.0 failure. It's essential to address these concerns to ensure all viewers, including hard of hearing and deaf people can access all web content.
Closed captioning services can help here by generating accurate captions for your videos. These tools are affordable, particularly for educational institutions, content creators, and small businesses.
To help you add captions to your videos, we've curated a list of the best closed captioning apps. But before that, let's understand some vital aspects of these tools.
Key Factors to Consider in Closed Captioning Apps
With plenty of closed captioning solutions available, choosing one can be confusing. Let’s simplify that for you.
Accuracy
Accuracy (in percentage) refers to how correct or exact a caption is to the spoken content. To achieve full accuracy, captions that a captioning application generates must exactly match the speaker’s words and be in sync with the video.
However, achieving 100% accuracy is highly challenging due to errors like context, language, human errors, etc. So, look for a caption generator that offers the maximum accuracy possible to achieve the best results.
Ease of Use
A closed captioning application must not give you a hard time with its functions or interface. Choose a tool that comes with a user-friendly interface that you can learn, adapt, and use easily.
Pricing
Most providers offer their captions on a per-minute basis, while others have monthly pricing. So, individuals and organizations must consider their budget and captioning needs in a month and choose a solution accordingly.
For example, if you are a beginner, look for free or basic plans with limited features. But for mass video production, look for enterprise plans.
Integration
Good caption services integrate with plenty of tools to make life easier for video creators, saving time and avoiding frequent tab switches.
Customization
The captioning tool you choose must allow you to customize captions and file-tune the content to match your content style.
File Format Support
Check how many file formats the tool supports. If it supports the ones you regularly use for importing and exporting, it should be fine.
Turnaround Time
The duration a tool takes to generate the caption for a video is turnaround time. It mainly depends on video length and is indicated in minutes or hours. Look for tools that offer faster turnaround time.
