I would like to add a notification to a video at some particular time period that "Mistake Lorem in this".
Does OSX have any default video tool (simple) to add any type of text (subtitle ok too) to the video?

iMovie may work for you.
Import your Movie and then.
1, Select the Titles in the Content library to pick Title theme
2, Drag the Subtitle Theme down to the movie strip.
3, Adjust the Subtitle time line to where you want it and duration.
4, Write you text in the text field.
5, Set your text style.
Another one that isn't built into OSX but Subler is an excellent, small, and free program for adding .srt files to existing video (in multiple codecs).
It isn't built-in to OS X, but perhaps this $9 tool might be what you're looking for.
Just looking for subtitles? Then look no further than Aegisub
If you need something free, built-in to OS X (and you have programing chops), perhaps OS X's Core Video and Automator are worth a look too.
Or can you be more specific?
If your video is in mp4 format, you can embed SRT subtitles to video using Subler. It's a free software.
If your video is not in mp4 format, you should go to Subtitle Writer on Mac App Store. It's an paid app for $4.99.
Both Subler and Subtitle Writer are making subtitle track in video so that Quicktime Player X or iOS devices can show them as Closed Caption.
If you just want to make few comments on video, you can make it in iMovie.
