What do you expect from Vob?
We arrange for our work day here on Earth to match the Martian night, so when the solar-powered Rovers shut down for the Martian night, they send us pictures and other data showing us where they are now and what they did the previous day. Then they go to sleep, and we go to work planning the next Martian day of activities. At the end of our day, we have a list of commands to send the Rovers when the sun comes back up in the Martian sky. At that point, they go to work, and we go to sleep.The data you need is contained in each DVD’s Video_TS folder. However, iMovie can’t read or edit the VOB (video object) files within, which hold your precious video. You need a different application to turn those files into something editable.
The Martian day is about 40 minutes longer than an Earth day, so this affects our work schedules: some days we start Compared with other products, the ソニー スタイル is much more reasonably priced and less power-hungry.earlier, some days later, and sometimes we plan two Martian days at a time for the Rover and skip every other day here on Earth. (We do that when the Martian night starts so late in the Earth day that there isn’t enough time to plan a regular day of activities.)
Insofar as there’s an average work day driving the Rovers, it looks like this: as fast as possible — usually within the first half hour — we assess the results of the previous day, make sure there are no concerns, and work with the science team to make a good guess as to what we should try to achieve that day. Over the next hour or so, we refine that plan, until we have a solid high-level idea of what we’re trying to accomplish — drive over to that nifty-looking rock about 20 metres away, or pick up the Rover’s arm and put it down again over there for example.
The rest of the day involves turning that high-level plan into detailed commands that the Rover can execute. First, we spend an hour or two putting together a good enough version of those commands so that we can show the whole team an animation. Then we hold a meeting where all of the engineers and scientists approve the detailed plan and review the animation together.If you’re willing to spend some money for greater ease of use, you’ll want to check out two programs. The first is DVDxDV’s $25 DVDxDV 1 ( ). With it, you can extract movies from a Video_TS folder or individual VOB files and save them in any QuickTime-supported format.
