//?? titleLayer.shadowOpacity = 0.5;
titleLayer.alignmentMode = kCAAlignmentCenter;
titleLayer.bounds = CGRectMake(self.rectText.origin.x,self.rectText.origin.y-52, 480, 480); //You may need to adjust this for proper display

Solved the issue see my below code. This was working fine with video.

CATextLayer *titleLayer = [CATextLayer layer];
titleLayer.string = self.strText;
titleLayer.font = (__bridge CFTypeRef)(self.fonts);
titleLayer.fontSize = fontsize;
titleLayer.masksToBounds = NO;
titleLayer.foregroundColor = self.textColor.CGColor;
titleLayer.alignmentMode = kCAAlignmentCenter;
//[self.txtVideoText setBackgroundColor:[UIColor colorWithHue:255.0/255.0 saturation:255.0/255.0 brightness:255.0/255.0 alpha:0.4]];
//[self setAnchorPoint:self.txtVideoText.layer.anchorPoint forView:self.txtVideoText layer:titleLayer];
titleLayer.anchorPoint = CGPointMake(0.5, 0.5);
titleLayer.frame = CGRectMake(xx,-(yy-CGRectGetHeight(self.viewHeader.frame)), 480, 480); //You may need to adjust this for proper display
[parentLayer addSublayer:titleLayer]; //ONLY IF WE ADDED TEXT
