i'm sorry,
"""i need help to fix 9 inch monitor, better than tablet for viewing and signal stability, on 2nd remote.""""
The tablet has very little to do with signal stability. Your use of the term "tablet" is so vague that I can only assume you're using a decent iPad. Even a relatively weak Air 1 will not bottleneck your video feed. Assuming you're using a tablet of reasonable power, signal instability is the fault of your signal strength vs. environment (microwaves) vs. your chosen channel. When your environment is loaded with microwave signal, "Auto" channel switching is your worst enemy. I did a video on "signal strength" here:
its not easy to use a tripod when filming outside.
If you hand the tripod and iPad to the DP, it's actually quite light and nimble when mobilizing to a different location (say 30 or 40 feet away). Generally speaking, while actively shooting, we don't move around much. My pilot might move around so that he can maintain LOS, but generally speaking, as camera op, I remain static as does the DP. YMMV.
If there's enough wind to blow over the tripod, there's too much wind to fly.
Regarding "foot, people," if you have a bunch of people running around after the director yells "action," then I don't know what to say. In American film production, all activity comes to a stand-still when the director yells 'action.' You must be shooting independent films.
i got 9 inch professional monitor, where brightness and signal is better.
I find that if reflection is a problem, you can take the iPad off the stand and the DP can stand in such a way as to keep the iPad in the shade. We try and stay in the shade anyway to avoid over-heating. I considered the Crystal Sky offerings, but they're too buggy. Too many complaints in this forum to trust that platform. When on set, my equipment must work perfectly. And it does 100% of the time.
i need to fix it with no tripods.
Copy that. I think you would find the $30 investment worth it just to have it on hand. The more comfortable you make your DP, the more points you will score with production. But I don't have to tell YOU that. That said, read above. Your reception issues are NOT due to your iPad. If you have an Android, then, yeah....that could be a problem. Get an Air Pro and you'll be good in that department.
i got it and have more more trouble when use it.
You mean you have an iPad stand and don't use it? Hmmmm.... We use it sometimes...not always. It just depends on the shot.
Let me know if the video I linked is germane to your problem and if it helps it.
