Screen recorder

Hi guys as u all knows well that I would love to share my chess knowledge with our group but i have one problem .II have no paid screen recorder.My current recorder allows me to post the video of maximum time  of 15 mins and sometimes Its so tough for me to complete a single game in 15 mins because analysis and rules and knowledge is so high in all games.I analise the game with myself and with my master and then i post them so Screen recorder become a big problem for me.

Can anyone help me 

I need full version of free recorder which allows me to post my own video sometimes nd screen shairing

I tried camstudio but it says I have to buy microphones for speaking.Maybe I have one in my real home but i do not think that it will work .I hope it will but anyways if here in our group anyone knows the free and full version of any software then help me.

this is the current recorder which I use

the paid version of this software costs about 15 usd .Right now I have nothing because in last 2 month  I spent all my money on my own chess lessons.

.

I hope anyone will find a good and free screen recorder for me which did not ask for any microphones or give me unlimited access of posting videos

Unfortunately, I am technically less knowledgeable than You in this matter. Maybe, You could divide these videos in 15 minutes parts. People who want to watch them and learn from them, hopefully, will not be disturbed by this.

but the prob is sometimes i cant post videos well .sometimes i have to speak very fast to cover the whole game.

So thatss why see my latest video  which i posted on my forum .I spoke so fast from the beginning

i hope u will like it too

Maybe, for the moment just post games with diagrams and elaborated analysis. In some cases, these are more helpful since people can follow them more easily.

but u know if we want to know strategy then u have to see the games from the beginning

Well: Fischer--Spassky part one, Fischer--Spassky part two etc. If You put this in the title, people will know in what order to watch the videos. I saw others do this.

oh tx for the suggestion

Ifi will win next month then i will afford to buy the recorder which i am using now

it only costs me about 29 usd for 3 yrs nd i m fine with that nd its so cool offer too 

but before it i hve ot win money for myself

but u know i love to complete one game in one video 

but if i speak enough then i only make a vidoe of 25 min or 30min not more than this 

so i think i wil have to buy it 

Most people would recommend OBS if you are asking about a free screen recorder. It supports Windows, Mac, and Linux, and have a waide range of options. But it maybe take you some time to figure out how it works at first. I myself use Joyoshare Screen Recorder cause it's more easy-to-use. Most importantly, I can capture videos with no time limit and no watermark.
