Kaltura - Performance and Accuracy
Evaluating Kaltura’s Audio Tools
Evaluating the performance and accuracy of Kaltura’s audio tools, particularly those driven by AI, involves examining several key aspects:
Audio Capture and Recording
Kaltura Capture, a tool within the Kaltura suite, is capable of recording system audio, which is a significant feature for capturing presentations or videos playing on the user’s computer. However, this functionality is limited to Windows PCs, as MacOS does not allow the capture of system audio.
Multi-Audio Tracks
For live streaming and multi-language support, Kaltura Live allows the use of multiple audio tracks. This feature requires specific configurations, including separate RTMP feeds for each audio track and a compatible encoder. While this feature is useful for events requiring multiple languages, it has limitations such as not working with seamless fail-over and issues with downloading recordings that include multiple audio tracks.
Audio Quality and Settings
Kaltura recommends specific video and audio settings to ensure optimal quality. For audio, AAC and MP3 compression are recommended, with stereo or mono channels and a sample size of 44.1 kHz or lower. These settings help in achieving normalized sound levels and avoiding issues like peaks or low sound.
Limitations and Areas for Improvement
System Audio Capture on MacOS
Kaltura Capture does not support capturing system audio on MacOS, which can be a significant limitation for users relying on this feature.
Interactive Features
Kaltura Capture does not duplicate interactive features like buttons or sliders in Flash-based animations, which might be a drawback for users needing to record interactive content.
Recording Failures
There are instances where Kaltura Capture recordings may fail to upload due to internet interruptions, memory issues, or encoding errors. Users need to follow specific strategies to resolve these issues.
Multi-Audio Track Limitations
Downloading recordings with multiple audio tracks results in only the first audio track being included, which is a known limitation.
Engagement and User Experience
Kaltura’s tools are praised for their engagement capabilities, particularly in webinars and events. The platform has seen high engagement rates, with features like chat, polls, and click-through options enhancing user interaction. However, the technical limitations mentioned above could impact the overall user experience, especially if users encounter frequent recording failures or issues with audio capture.
Conclusion
In summary, while Kaltura’s audio tools offer several advanced features, such as multi-audio track support and high-quality recording capabilities, there are specific limitations and areas for improvement. Ensuring compatibility across different operating systems and addressing the known issues with recording and uploading would enhance the overall performance and accuracy of Kaltura’s audio tools.
