I am using APowerRec (free download). It appears to have a 3 minute time limit. Is that true? Thanks.
By purchasing the software to support the developer...
They say everywhere that Apowersoft Free Online Screen Recorder has no recording limitations, though.
And if there is, maybe it's possible to create several records and then stick them together.
Maybe you need to purchase the full version. I use Joyoshare Screen Recorder, it is free for 3 minutes. Then I buy the full version. It can record without timelimit. The quality is high.
