2010 MacBook Pro Processor

There's several versions from that year which specific chip and speed were you asking about ?

'Video editing' loads different parts of a MBP - the CPU, the GPU, graphics RAM, RAM and the hard drive itself - all of these have an impact on how fast you can work.

Which software are you using to video edit with, iMovie, Final Cut Pro or something else ?

What sort of source files are you loading and editing, AVCHD ?

As you can see asking a broad 1-10 question really can't be answered without a lot more specificity (and even then is going to be rather subjective).

I would give it a 9 or 10, but knowing more about the processor in your particular case would help. We need a better description of what is in your MBP, i.e., processor, RAM, video card. Most of the MBP machines will do an excellent job with video. Apple had used the latest processors in the 15" and 17" MBP machines.

The 2010 13" MacBook Pro has a Core 2 Duo CPU. That CPU was somewhat outdated even in 2010 when most manufacturers were using first gen "i" series processors (all new Macs have 2nd gen Sandy Bridge processors). From a processor standpoint, it's dual core with each core running a single thread. It should be tolerable with Final Cut Express... but depending on what you're doing with After Effects, it can be a fairly heavy load on the CPU. Bumping your system up to the maximum amount of RAM would probably help you somewhat.
