【讓電影鏡頭自動對焦——dji transmission】13499元！大疆發布dji transmission無線圖傳接收器標準套裝

OK,hold up,stop what you're doing DJI just released a new stand-alone transmitter and receiver for you to have a wireless connection OK,that doesn't sound very interesting until I tell you that if you use this in conjunction with some of the other products I have available you can actually get a lens like this,the Tokina Vista Prime,and you can give it autofocus We'll get there Now,right out of the box,you're gonna get the usual suspects You're gonna get the stand-alone transmitter,you're gonna get the stand-alone receiver,the cables that you're gonna need for it and you're also gonna get an SDI cable that's going to come in this package Also,you're gonna get things like your batteries and the charger and all that other fun stuff Now,these two are actually a little bit smaller than the Teradek system but they are bigger than other wireless monitors that I've used before However,the build quality on these are great because they feel really sturdy,they're built to last and you also have a bunch of different options for battery and you're also going to have the reinforced connection by having four antennas on each one Now,this guy and other DJI products are pretty easy to set up So make sure you do update the firmware and all your DJI products in order for you to use all the functionality that we're going to talk about in this video Now,the DJI stand-alone transmission combo has one of the longest ranges that I've ever seen and it's written down to actually have a 6 kilometer distance between the transmitter and the receiver Now,DJI also reports a really low latency which is only going to be about 7 milliseconds Now,it's not necessarily a Teradek system but Teradek systems cost you the same price as,I don't know,a human life So,you're going to be able to pull focus on this guy or if you want to use it as a client monitor,you can still do that as well and it's not a gigantic latency between the action and what you're seeing Now,speaking of actually showing this to clients or showing other people that are going to be on set whether the control function or the broadcast function you're actually going to be able to connect the transmission system from DJI to an unlimited amount of receivers in broadcast mode Now,being able to hook up to an unlimited amount of receivers is actually going to be a really handy tool especially when you don't want people to breathe over your shoulder and you don't want to find out what they had for breakfast you can set one of these up to each screen that you're going to have on set whether you have 2,3 or 67 of them and you can make sure that you have enough space for you to get the shot that you need without somebody kind of hovering over your shoulder which actually is kind of annoying because the pandemic's over but I still want you to keep 6 feet away from me Now,one thing that I do like about DJI is that a lot of their components and a lot of their accessories are all compatible with each other and using the transmitter and the receiver on this as well you can actually use a couple of different things in order for you to give your cinema camera autofocus no matter what lens you're going to be using Now,follow me here Now,the first thing you're going to need to do is you're going to need to have the LiDAR system already a follow focus motor and you're going to need the new LiDAR hub that you can get with this setup On top of that,if you're somebody that does have the high and bright monitor from the original transmission system you could use the accessories like the handles on the Ronin 4D or you could actually pick up the standalone focus motor in order for you to control the focus that's going to be used through the LiDAR system Now,you're probably already going to have your transmitter set up on your camera either using HDMI or SDI and connected to a receiver But when you are using one of the DJI monitors you can do this without needing a receiver at all which means that you actually are going to have a free receiver in order for you to connect this to a client monitor while somebody else pulls focus for you Now,when you are using the high and bright monitor which I'm going to use with the Ronin 4D handles you can go into your menu settings and you can calibrate the lens sort of like how you would if you were using the DJI RS3 That means that you are able to use a LiDAR system with the autofocus without you having to buy a gimbal in exchange Once you've calibrated your lens and you've set a profile for it you are going to get a picture in picture with a little autofocusing square that you're going to see on the DJI LiDAR system Now,I'm still testing out the Red Komodo X and I want to put it through some of the real-life situations that I find with different client shoots So,of course,we're shooting at a gym I was doing just enough to get by I was working on a job They paid me just enough to keep me from quitting And I worked just hard enough to keep from getting fired How many know people like that? Blink your eyes and you'll understand what I'm talking about I was parked I knew I could do more But when my mama died She took something out of me That's why they say that life is like a noodle You have to peel it And sometimes you cry Life's going to happen to you when you have a dream So,I decided to take everything and put it through its paces in a real-life shoot situation And actually everything performed just fine Now,I will admit that we did get a little bit catfished in terms of our location And it was much smaller than what I expected it to be Now,the reason why I bring that up is because the range test on here was a little bit hard to do Now,I'm somebody that lives in a gigantic city with a lot of cars and power lines and things like that So,it is really easy to get a lot of obstruction when getting a straight line of sight test in order to find out how far that 6 kilometer is in terms of the transmitter versus the receiver But I was only able to get about a quarter mile away from my transmitter when I stopped the receiver in my car and I started to drive off Now,you are going to have two modes on the transmitter and the receiver You're going to have a control mode and you're going to have a broadcast mode Now,the broadcast mode that we talked about before is going to give you more things to connect to However,you are going to have a reduced range So,you're not going to be able to get as far in broadcast mode However,when you're using control mode you actually might have less items to hook up to However,you're going to get a stronger and a longer connection However,for me,a quarter of a mile or 370 meters which is really close to a quarter of a mile is more than enough distance And I'm not that far away from my camera mostly because it's expensive Now,in terms of the LiDAR focus using this entire system it actually worked pretty decently which is kind of scary I was able to actually use the LiDAR auto focus for some shots But I also want to use a manual focus to see the latency between the transmitter and the receiver that's already built in the high and bright monitor And I wasn't pulling focus I had my buddy Isaac doing it and he did just fine because a lot of the shots there were completely sharp Now,in order to get this entire system there are a couple of different moving parts But there is one thing that I want to point out especially when you're setting up the focus motor Now,what you might want to pick up is going to be one of these guys Now,this is a 15mm rod to a 12mm rod adapter Now,what you're going to do for this guy is because the focus motor from DJI has a 12mm rod input it doesn't really fit in the standard 15 which I found out the hard way when I was trying to set this guy up But once I got this set up I was able to put it in my 15mm rod clamp that's going to be on my cage And I can connect it just fine by just using this end and it goes into the focus motor Something that you might want to keep in mind and something that you might want to know Now,I did mention we did use the LiDAR system when we were using it on the Tokina Vista Primes Now,again,this actually worked pretty decently as far as using an autofocus system on a gigantic cinema lens However,something I might recommend for you is that you might want to use smaller lenses Oftentimes,when you have big lenses the big focus rings need a lot of force to actually end up turning the ring And when you're using a little tiny focus motor like this guy Albeit it works You might not have as much luck when you're using bigger lenses that might have more stiffer focus rings So,if you are going to use a LiDAR system you might want to opt for some smaller cinema lenses like the Diesel-to-Vespa Primes or whatever have you Now,it's time for the fun part and we're going to talk about pricing because these aren't cheap but they are really highly functional Now,if you want to pick up the stand-alone receiver you're going to be looking at about $1699 Now,you might want to pick up the stand-alone receiver because you might already have the transmitter-receiver combo where you actually got the monitor instead of another stand-alone receiver unit So,you might actually be able to not only connect to an external monitor but you could also use your high and bright monitor to use things like the LiDAR function that's going to come a little bit later Now,if you do want to get the handles in order to use a LiDAR those are going to be a separate thing And as well as you want to make sure that you have the LiDAR range finder the focus motor and all the other necessary accessories in order to get the LiDAR to work But there is one thing that's actually the cheapest in this video and it's going to be the LiDAR hub This is only going to be about $90 and you're going to need to connect everything into this hub in order for you to use LiDAR without using a gimbal On top of that if you don't want any of the stuff at all and just want a transmitter and receiver you could pick up the standard combo for $24.99 Now,you might be wondering $24.99 might be a little bit much in order to get a transmitter and a receiver And for some of you guys who are looking to save a dollar then this might not be the video for you Now,where the positioning is for this system is going to be more on the higher-end budgets and more professional type of shoots Now,there are going to be cheaper receivers and transmitter setups that are going to be available But what you might run into is going to be a weakened strength of connection You might run into some range issues And you're not going to be able to hook up to a LiDAR system and get all that functionality if you want to expand and move through this ecosystem Now,if I'm going to make a wild guess in terms of what DJI is setting the system up for is I think they're actually competing with some of the more professional wireless systems particularly Teradek And when you compare the price between all the accessories that you're going to need to get to get the LiDAR functionality the transmitter,receiver and all that other stuff You're still spending less money than if you had bought a Teradek in the first place Which means that not only you're going to get a more than decent system in order to get wireless transmitting for polling focus or for client work You can also give the Tokina Vista prime autofocus Which is still something that is weird when I say it out loud But it works That being said I hope you guys enjoy the video or at the very least you learn something Now,wireless transmitter systems they're not the sexiest thing in the world in terms of camera gear However,they're incredibly useful on more professional sets And especially when you have something like a focus puller or clients that you don't want over your shoulder It actually comes in handy That being said I did leave a video somewhere on the screen over there And a special shout out to DJI for actually sending me this system So I could show you guys how you can give any cinema lens autofocus I'll see you in the next one I'm going to stop talking Peace
