As you can see on this link:

/video-upload/

after click submit button, wp says me e-mail is invalid but I enter valid e-mail.

Array ( [email_valid] => Email has no valid value )

related code:

  if(is_email($email)) {
            $error['email_valid'] = "Email has no valid value";
        }

full code:

<?php
/* Template Name: Video Upload */

get_header();

    global $wpdb;

    if ($_POST) {

        $username = $wpdb->escape($_POST['txtUsername']);
        $email = $wpdb->escape($_POST['txtEmail']);
        $password = $wpdb->escape($_POST['txtPassword']);
        $ConfPassword = $wpdb->escape($_POST['txtConfirmPassword']);

        $error = array();
        if (strpos($username, ' ')!==FALSE) {
            $error['username_space'] = "Username has Space";
        }
        if(empty($username)) {
            $error['username_empty'] = "Needed Username must";
        }
        if(username_exists($username)) {
            $error['username_exists'] = "Username already exists";
        }
        if(is_email($email)) {
            $error['email_valid'] = "Email has no valid value";
        }
        if(email_exists($email)) {

        }
        if (strcmp($password, $ConfPassword) !==0) {
            $error['password'] = "Password didn't match";
        }
        if (count($error) == 0) {
            wp_create_user($username,$password,$email);
            echo "User created successfully";
            exit();
        }
        else print_r($error);
    }

I was just missing the "not" operator (!) in my conditional (if(is_email($email))), which in turn resulted in valid email addresses being treated as invalid. So I added the ! and that solved the problem:

// code before; incorrect - missing the !
if(is_email($email)) {
    $error['email_valid'] = "Email has no valid value";
}

// code after; working as expected after I added the !
if(! is_email($email)) { // if email is invalid, add the error message
    $error['email_valid'] = "Email has no valid value";
}
