I have a straight forward, but important question:
Let's say my camcorder outputs to mpg 2 at 8mb bitrate.
I capture the footage, add transitions and tweak colors
and then render right back to mpg 2 with the same bit rate.
Have I lost any quality?
Thank you for your answers.

Yes. You would have to encode at a higher bitrate to have close to the same quality. Most all codecs are lossy and the quality deteriorates when re-encoding. Some codecs are lossless, like HuffyUV or Lagarith. But the files are huge.
But try a short encode with representative clip from your video. Use the same bitrate and judge for yourself. The quality loss may not be that noticeable.
And welcome to our forums.
Excellent response redwudz
My add is if this MPeg2 video is 8 bit standard def, then the recode loss may be worth it if the levels were way off. Save the original file for future technology.
But the policy wonks are going to bang me over the head anyway.
So like RedBudz said, make a copy and try to judge for yourself.
Oops, I guess "RedBudz" was a freudian slip. I meant RedWudz,sorry.
Thank you for your responses!
You know, the thing is, the color editing you did could have caused a loss in quality too. Are you an expert colorist? Hahaha, no doubt you're broken all the rules there too.
So if you do a no-no, but nobody notices, did it really happen? Or was that your "intent"? Nobody knows.
