1.Trial commences when charge sheet is submitted.In charge sheet the police discloses each and every piece of evidence which it collected in support of the case of the prosecution.
2.Now In your case the police certainly did not seize the video footage and if that is so it did not have any reflection the charge sheet.
3.in that event during recording of your evidence or other witnesses the video footage cannot be produced atall.
4.You will have to rely on ocular evidence of the complainant and witnesses if any.
I regret there is no other way out.
