alxltz: There are some pre-rendered cutscenes in BloodRayne 2 which were originally letterboxed (with black bars on the top and bottom) for intended 4:3 displays which in Terminal Cut now scale to fill a widescreen 16:9 display without the need for the bars. Note that not all BR2 cutscenes were originally letterboxed, though; this was only the case for certain pre-rendered scenes (I won't say which ones to avoid spoilers).

BloodRayne 2: Terminal Cut also has a menu option (accessed from main menu via Options > Display) to choose between viewing cutscenes in their original aspect ratio (this is the default) or in a 'widescreen' presentation that will punch in on the image to fill a 16:9 display for all pre-rendered cutscenes (whether or not they were letterboxed in the original PC version). This 'widescreen' cuts off parts of the image for those cutscenes that were not originally letterboxed, but is there as an option for people who prefer their 16:9 screen to be full on as many cutscenes as possible.

alxltz: For BR1, the pre-rendered FMVs are presented at their original aspect ratio, though again black bars are cropped out of the ones that were originally letterboxed.

Terminal Reality investigated the possibility of moving the HUD elements further to the edges of the screen to better suit widescreen view in BR1, but they said that due to the way UI was coded in the original game it had a high likelihood of causing unintended bugs in the UI. For this reason they felt leaving the HUD elements where they are would maintain the original experience and avoid bugs they expected could occur.
