I would like to post my screen capture video on YouTube. After viewing the uploaded video it is too blurry to make out any detail. I made the option to watch in 1080 but it still did not help. Should I record in a smaller format to match what YouTube is compressing my video to??

I am using a large screen for the capture but can use a laptop if neccessary. Please advise me on the correct settings to publish screen capture to YouTube with a clear playback.
thanks
