VoiceThread commenting is quite flexible and robust, so you won’t often encounter limitations on each comment. There are some limits, however, and it’s a good idea to be aware of them. Note that there is no limit to the number of comments you can record, so if you really do have a lot to say, you can record multiple comments on a single slide.
- Text – No limit.
- Audio – 60 minutes per comment.
- Video – 60 minutes per comment.
