Well, let's look at the goofs in this one:
A very few scientists, most notably Alan Feduccia, think that dinos and birds are cousins, both having evolved from thecodonts. But because of the evidence, most scientists don't agree with him.
As one expects, this guy retreats into his religious beliefs, claiming that his new doctrine of YE is the Christian view. It's actually a new invention, from the Seventh-Day Adventists, in the early 1900s.
He expresses surprise that one might think reptiles might be warm-blooded. In fact, we see that the theropods were feathered, especially the small ones. Insulation only makes sense for warm-blooded creatures. They have Haversian canals, which indicates a very active, warm-blooded lifestyle. It's difficult to see how a cold-blooded animal could manage a running, predatory lifestyle such as that of velociraptors.
And of course, he's got it completely wrong about lungs:
Bird-like respiratory systems in dinosaurs -- A recent analysis showing the presence of a very bird-like pulmonary, or lung, system in predatory dinosaurs provides more evidence of an evolutionary link between dinosaurs and birds. First proposed in the late 19th century, theories about the animals' relatedness enjoyed brief support but soon fell out of favor. Evidence gathered over the past 30 years has breathed new life into the hypothesis. O'Connor and Claessens (2005) make clear the unique pulmonary system of birds, which has fixed lungs and air sacs that penetrate the skeleton, has an older history than previously realized. It also dispels the theory that predatory dinosaurs had lungs similar to living reptiles, like crocodiles.
The avian pulmonary system uses "flow-through ventilation," relying on a set of nine flexible air sacs that act like bellows to move air through the almost completely rigid lungs. Air sacs do not take part in the actual oxygen exchange, but do greatly enhance its efficiency and allow for the high metabolic rates found in birds. This system also keeps the volume of air in the lung nearly constant. O'Connor says the presence of an extensive pulmonary air sac system with flow-through ventilation of the lung suggests this group of dinosaurs could have maintained a stable and high metabolism, putting them much closer to a warm-blooded existence. "More and more characteristics that once defined birds--feathers, for example--are now known to have been present in dinosaurs, so, many avian features may really be dinosaurian," said O'Connor. A portion of the air sac actually integrates with the skeleton, forming air pockets in otherwise dense bone. The exact function of this skeletal modification is not completely understood, but one explanation theorizes the skeletal air pockets evolved to lighten the bone structure, allowing dinosaurs to walk upright and birds to fly.

fingers in embryology not clear as he claims.
And he's got it very wrong about feathers and scales. In fact, one can change scutes (scales found on dinosaurs, crocodiles, and birds) into feathers.
From an Old Earth Creationist website:
Scutes are the thick scales on the top of a bird's foot. Smaller scales on the back of the foot are called scutellae, and scales on the bottom of the digits are called reticulae. Analysis of these shows that scutes, scuttelae, claw sheathes, beak sheathes, and scales around the eye are of the same chemical composition as feathers, and are controlled by the same genes!4
So, scale to feathers is very much possible, from a genetic standpoint! We may never know the final answer on this, but it is clear that from a genetic standpoint, scales to feathers is very possible.

Requirement for BMP signaling in interdigital apoptosis and scale formation.

Abstract
Interdigital cell death leads to regression of soft tissue between embryonic digits in many vertebrates. Although the signals that regulate interdigital apoptosis are not known, BMPs--signaling molecules of the transforming growth factor-beta superfamily--are expressed interdigitally. A dominant negative type I BMP receptor (dnBMPR-IB) was used here to block BMP signaling. Expression of dnBMPR in chicken embryonic hind limbs greatly reduced interdigital apoptosis and resulted in webbed feet. In addition, scales were transformed into feathers. The similarity of the webbing to webbed duck feet led to studies that indicate that BMPs are not expressed in the duck interdigit. These results indicate BMP signaling actively mediates cell death in the embryonic limb.

Not knowing what one's self is talking about can be a big problem.
