Two WTC 7 collapse videos: Can both be real?

Consider the following two WTC 7 collapse videos

• Northwest alleged CBS video (MPG) on Jim Hoffman’s WTC 7 site, shot at street level northwest of WTC 7, obtained by Jim Hoffman from “plaguepuppy,” whoever that is. Another copy (WMV) and a slow-motion zoom version (WMV) on What Really Happened.
• Northeast privately-made video (WMV) on What Really Happened, shot from a window of a nearby building northeast of WTC 7.

To my admittedly untrained eye, these two videos look too different from each other for both of them to be genuine, unaltered recordings of the exact same event from different angles.

Why this is important: The northeast video, if genuine, substantially weakens the “symmetry of collapse” argument regarding WTC 7. Hence, if the genuineness of the northwest video can be established, and if the incompatibility I percieve turns out to be valid, we can thereby disprove an important piece of alleged evidence against the “symmetry of collapse” argument.
