    Why? It's either going to work or it's not. We've bought plenty of them - DLT4000 (at least three), DLT7000, DLT8000 (2 of these), DLT80, LTO2, LTO4, LTO5, LTO6, LTO7. All used. All have made hundreds of tapes with no issues. All tapes verify correctly, and all of the tapes made work on client systems. These are robust machines, designed to run tens of thousands of tapes in their lifetimes. Most of the used ones were upgraded by IT departments when they moved to a newer format, so they've depreciated somewhat and they're just looking to recoup costs. Just look on ebay and you'll find them used and refurbished. You might need to buy an internal drive and a separate enclosure for it to get the best deal, but putting them together is as simple as installing a hard drive. Here are recent sales on ebay: https://www.ebay.com/sch/i.html?_nkw=lto5+external+drive&_sop=15&rt=nc&LH_Sold=1&LH_Complete=1

    You can't possibly rely on a video image as a reference for film exposure- you have no idea how much gain is being applied to the signal for a start. You must learn how to use a meter properly. A DSLR may help a bit, but again the way it responds to light isn't quite the same as film.

    Sometimes the green screen can not be placed at a distance that simulates the background plate. And in this case it's up to the artistry and skills of the VFX artist to create the best tracking of the background. I have an example of this at the 3 minute mark in the clip linked below. This shot was made in a studio set of a boardroom in an office tower. The city seen out the window is computer generated. Even though we used tracking marks on the green, it was probably not very helpful for the FX artist as the distance to the green does not match the distance to the city out the window. So this became a not easy and expensive DFX shot. The chroma key shot begins at 3:00.

    Impossible to say without knowing what kind of vfx elements you are going to add afterwards and the special paths the camera is moving and what kind of tracking software you use and how wide the shot is etc. It may vary from a single tracking marker to hundreds and the optimal marker shape can vary as well. Sometimes it may be even more practical to shoot a certain shot without the greenscreen with using normal background to get enough tracking data and then just roto the subject instead of keying. A basic distinction would be whether you will do 2d or 2.5d tracking or 3d matchmoving and whether you use point trackers or planar trackers or both and how many you need to see at minimum on each frame to be able to track reliably. Have you hired a vfx supervisor for the shoot, he/she can check the shots you want to do and tell how it's easiest to archive them? We can try to give some suggestions here as well if you tell all the necessary details about the scene and individual shots
