Most people thought the special effects in Transformers were pretty dang awesome. For the most part they were. However, there are a few shots that really stand out as not being up to scratch with the rest of the film. The main culprit (the one I'm gonna focus on) is the discrepancies seen when they swap over from physical model stand in to CGI robot. Let's start with Bumblebee: We've all seen the huge lifelike model they built of him. It looks a bit like plastic and it's squeaky clean. Unfortunately it contrasts greatly with the ULTRA REAL battle damaged CGI robot version. If you've got the film handy fast forward to the 1 hour 30 minutes mark and rewatch the "capture of bumblebee" scene. You'll see them swap back and forth between the model and the CGI. Observe... CGI: He's dirty, grimy, very reflective and very clearly metallic in parts. Looks pretty good eh? In motion he's moving around a lot too. Model: What is this? He's clean... dead still... not as detailed... pretty obviously the model stand in. The problem is that they kept cutting back and forth between CGI BB (who moves around a lot) and model BB (who is dead still) in this scene. For some reason it really bugs me and is pretty unconvincing. If they had edited it a bit better and started with CGI and then ended up with just using the model (he is in the process of being frozen, so it makes sense that he'll eventually be still) it may have been somewhat better. If you're excited there's some parts in Secter 7 HQ where this happens again but I didn't really feel like capping them. Next up, Frenzy! This is from the Airforce one scene, about 30 minutes into the movie. This is even worse than Bumblebee. Here's puppet Frenzy: It's only a few shots and could have easily been done in CGI. Instead we get this horrible puppet Fenzy that moves completely different to his CGI counterpart. A huge mistake is to cut straight from a shot of full bodied puppet Frenzy to a shot of the CGI Frenzy walking and dancing about: And a few moments after that we're treated to a facial close up: Looks a lot better than the puppet eh? So, uh, did this piss anyone else off?
