Form flickers when changing image on 1 tick delay

I'm trying to create a title screen for a C# Game i'm making. I created a video to use as the background for the title screen, and extracted the frames to JPEG files. Using this:

    int frame = 1;
    private void timer1_Tick(object sender, EventArgs e)
    {
            if (frame == 901) { frame = 1; }
            this.BackgroundImage = Image.FromFile("src\\titlescreen\\0 (" + frame + ").jpg");
            frame++;
    }

The form flickers when changing the image. The timer is on a 1 tick delay.

Is there any way to stop this?

Additional info: The form is maximised.

Thanks in advance,
