One thing I really stress when training video evidence Technicians & Analysts is to stay in your lane. Don't go beyond your training & experience levels on any topic/tool/etc., no matter who is asking you to.
A related one is that an expert's job at trial is to leverage their expertise to make sure the Trier of Fact has accurate evidence & information, not to be an advocate for one party or the other.
I've had several students over the years tell me that my passionate articulation of one or the other has saved their case or even their career. Two rather recently.
Honored & proud, of course, but I always like to point out to them that they are the ones that did all the hard work and stood their ground.
Keep being great & doing great things my friends! 😎
