I wish I could say people will be supportive and all will be well. Sadly, my experience has been that the victim is most often receives far less support than the attacker.
People do this for several reasons. Those who have been sexually harrassed as well (maybe even by this person) may be upset because you didn't tolerate it and they did. This means that their choice wasn't the only one they could have taken and people tend to be upset when people don't make the same choice they do (Heck you should have seen the vitriol I got at one place for putting in my notice when they all hated the place too). When you go against their choices, people often feel as if you are judging them even when you are not. I think it is the betrayal of those who have also been harrassed that hurts the most because you would expect them to understand. But if they didn't take the same action, they often feel you betrayed them.
Others (especially managers of the opposite sex) will be upset with you because they are afraid you will do the same thing to them. They will feel they can't make a joke in your presence or that they can't be alone in a room with you even for things like performance appraisal where they should be alone with you. They don't know where you draw the line and thus they will always be afraid you will have them arrested as well. Yes, I know you probably wouldn't if they don't physically attack you (which is what I'm guessing happened since you say there is video eveidence). Sometimes people who are not harrassed have no idea how much hell you went through before you had to do something. They will think this is a one-time incident that came up out of the blue and that you might turn on them at any moment for something totally trivial.
There will be people who just absolutely can't believe that Joe would do that, so you must be in the wrong. He's a good family man with a wife and three kids. He couldn't possibly do what she said he did.
There may also be an element of "She thinks she's so perfect, I'll show her."
So be prepared to have to work twice as hard to get half the credit you used to get. Be prepared to be misjudged for every thing you say. Be prepared to have your most innocuous statements be misinterpreted and have people threaten (or actually) to turn you in for things at the drop of a hat. You may find moving on to another job is the best option. If you do decide to seek other employment, do not mention this issue when asked why you want to leave. Interviewers may very well interpet your explanation as "This person is a troublemaker. Do not hire."
You will need support to get through this. Try to get as much suport from people outside the workplace as you can.
I know how hard it is. I was attacked in the office in full view of 20 people. All of them told me they would lie on the stand if I had the guy arrested. My boss told me that I could forget about ever getting any promotions (I was very junior) and then they sent me on work-related, out-of-town trips with the guy. I didn't have him arrested and have regretted it many times since then.
You have more courage than I did. So I salute you. And I wish you well. And I hope your workplace reacts better than mine did and better than I have seen it react many times over the years to many people with similar problems. But be prepared for it to be very bad at work and then it is nice surprise if it is not. Stand tall, be proud of yourself and let the chips fall where they may. At least you can live with yourself.
You have a legal case pending, so it is best to deflect all comment with something along the lines of "I can't talk about the case."
And make sure you have legal counsel. It's not fair that the victim has to protect herself from retaliation, but it all too often is the case.
