Need this cleaned up

I require video enhancement services for an upcoming legal case. A key piece of evidentiary video contains unclear images and significant background noise that must be improved to be clearly understood and presented in court. The selected freelancer will need to utilize their video editing expertise to enhance the quality of both the visual and audio components of the video file provided. This includes reducing background noise interference to more clearly isolate and amplify the conversational dialogue present. Captions of the transcribed speech between individuals will also need to be incorporated into the final edited video file. Watermarking with relevant identifying information like the associated case number and exhibit designation is necessary. The refined video file once completed will play a crucial role for the legal proceedings. Strong video editing and audio filtering skills are required to cleanly improve the content and transform an unfavorable raw video file into a clear presentation-ready exhibit. Attention to fine detail is important as the work produced will be carefully examined and evaluated in a court of law.
The sample provided is just some quick screen recording of the roughly 3 minute video. Original video size is about 23mb. I'll give more details upon samples.
