The judge does not have to dismiss a case just because one piece of evidence is favorable. Because I am sure that when your lawyer makes an argument to dismiss, the prosecutor makes an argument that the case should continue. That means the prosecutor believes he's still got enough evidence which, when it all comes out, will prove the case against you beyond a reasonable doubt.
So if the prosecutor believes he can get a conviction -- even if he ultimately turns out to be wrong -- he's entitled to try to go forward. And the judge is entitled to wait for all of the evidence to come out before him to make his decision on the case.
If you did not commit a crime, you don't have to take probation for a year, for 6 months or ever at all. Regardless of how hard the prosecutor and the judge are pressing to get you to take a deal, you are free to insist that the case go to trial and to confront all the witnesses against you and challenge the evidence. For whatever reason, the state believes they have a good case against you. So the nature of the system is to push to get you to admit your guilt. It's an adversarial system. As much as you and your lawyer believe this case should be thrown out, the prosecutor and the judge believe that you were properly charged.
You don't have to buckle to the pressure and take any deal at all. If you want your day in court to get this all before a jury and prove that you did nothing wrong, you'll get that opportunity.
I wish you luck with your case. If the video does indeed say it all, the verdict ought to be in your favor.
