Capturing model scenes.

Postby weaver » Tue Dec 25, 2018 12:43 pm

Recently I produced several model videos. ( part of them are on YouTube). The model railroaders were very happy with the results but few people from the YT viewers complained about the relatively high speed of the trains.
I do not know, how do you see it?
Here are just few explanations what may be the problem. ( many scenes in the recent film were slowed down electronically to get better results. ).
Here is my opinion:
1. The cameras on model layouts capture usually the bigger areas ie on the monitors we see bigger part of the "miniature world" as we would see in the real world. Most of those layouts are just few square meters big, ie from the single position it easy to see the whole miniature world. The cameras should reduce this view to size we would see it in the reak world.This cheats our sense for the size and for the distances.
2. The longitudial scale in model railroads is almost never correct, while the model trains are downscaled by certain factor (1:160, 1:120, 1:87 etc) the distances are far away from this reduction. ( in Europe the shortest station is about 800 m long what in 1:100 scale would be about 8 m). In the reality even on big modular layouts the yards are almost never longer than 2-3 m. This means the model train even on correct speed will pass the yard in 1/4-1/3rd of the real model time!
3. Most of the small models are running anyway faster than the scale would require and they do not have the weight to compensate the jerky motion. On top of that if you try to run your trains really on scale speed the visitors will be extremely unhappy - we tried this on one big modular layout the trains were running on their calculated speed, almost every visitor complained why are they running so slow. :-)
4. This speed is very critical in low speed range, when the train starts to move. Most model trains starts to work smoothly above the calculated 3 km/h (2 MPH). This is too much watched over a camera. The train jumps from stop immediately to relatively high speed a smooth start is almost impossible.
5. The electrical pick-up of the model trains is far away from perfection ie. In lower speed we often get choppy movement, what is even worse on video. In the reality very often I did not realized the motion problems, on the video I had lot of work to compensate or mask this choppy motion. Especially when the trains left the yard over many switches. Almost on every switch the locomotives were hesitating, stopping or jumping what is not very ideal on video.
6. On model videos we try to place the cameras as close as possible to the trains, to get the illusion of the real world and to show the miniature details. If you stay along the line that close to the train as on the model videos, the real trains will pass by also very fast even at lower speeds. Ie our sense is quite relative.
7. What I am missing in VS is the variable slow motion, ie with some ( preferable external cintrol device) i can adjust the play back speed down to stop ( like a brake in the car or locomotive). In sport studios they have a slow motion control panel with a lever to modify continously the play back speed.
What do you think?
