You're submitting input field with another names, you input names should be match.

Try this code.

public function tambah_aksi()
{
    $data = [
    'ket'       => $this->input->post('keterangan'),
    'tgl'       => $this->input->post('tanggal_rekam'),
    'video'     => $this->input->post('bukti'),
    ];

    $this->m_uploadv->input_data($data, 'tb_uploadv');
    redirect('uploadv/index');
}
