Let me know any questions you have about the MARS 400S and i'll do my best to answer them :) Hope you enjoy the video

[@younken24films]

Have been wondering about these units. Love it! Thank you! BTW, as far as wired HDMI long runs, I tested a 35 foot cable and it worked fine. Then I installed it through a ceiling. It was working both directions for a short time but now it only sends the picture and has lost the ability to receive control from the ATEM Mini Pro. Have you any thoughts on that?

[@dansettle4931]

What is the approximate difference in latency between the 3 modes (balanced, speed, image)?

[@EasyyokeFilms]

@@younken24films Buy a Fibre optics HDMI cable. Works well even at 300ft and it sends all the information to ATEM with the ability to receive control from the ATEM to the camera and guess what it is quite cheap. 4K Fiber Optic HDMI Cable 200 Feet, HDMI 2.0 18Gbps, Supports 4K 60hz(4 4 4, Dolby Vision, HDR10, E-ARC, HDCP2.2) 1440p 144hz, One-Way Work www.amazon.com/dp/B07PYQNSR6/ref=cm_sw_r_wa_apa_i_Ad.dFb374R7TK And yes, it has been tested. Even at 300ft, the camera control works perfectly fine

[@JulioZavala83]

Hi can you still control the bmp4k with atem switcher? With this wireless system?

[@milagrostephen4549]

Can i use this for live streaming in the church? like my dslr, Mars 400s and a VIDEO MIXER

[@shawndonnelly862]

I purchased two sets of these a few weeks ago for a outdoor graduation that we streamed live. They worked flawlessly. The distance to one of the transmitters was about 200 feet and the other about 100 feet. I also used wireless mics (PicoGear) to the most distant transmitter (mounted on a C100ii) and it was also connected to a iPad Pro in another location inside a building. There were no problems. They were connected to my ATEM mini pro then out to KZbin. Other than a bandwidth issue that was caused by the audience which forced me to drop 720p, the 400s units were amazing. The Mars 400s units and the ATEM mini pro have made my amateur steaming experience so much nicer!

[@stevef]

Great review. Thank you Tom Cooper for your question. I have a BM URSA Mini SDI and moving away from Tricaster (it is old) to getting the ATEM. This is awesome for being a mobile unit and not worrying about cables or unknown setups. I know you can use the BM converter box which is much cheaper. Also, thanks for running through all the various use cases. This helps justify the price when it comes to be needed.

[@kerrykikker]

Top class review, Alex. You answered all my questions on this interesting piece of kit. I'm off to buy the Hollyland 400S (maybe 2 sets) for my streaming sports operations, on your very comprehensive & straight talking recommendation. Looking forward to your next 'clever piece of kit' review.

[@AlexPettitt]

Thanks Bob! Really glad to hear this! Let me know how you get on with your units when they arrive....I'm always interesting in hearing how people are using them :) Cheers

[@bluemonster7754]

Great video sir! I have two Mars 300 Pro Enhanced transmitters and I haven't had any interference issues between them. However, it is susceptible to RF interference. I recently livestreamed one my indoor electric karting league endurance races and ran the transmitters through my Atem Mini Pro and there were plenty of times when the go karts came racing by that the signal would jam or blackout momentarily then reconnect the signal. Understanding that the intended purpose for this device is for monitoring only, I saw some slight latency with audio, but was negligible from my perspective. Additionally, I want to thank you for your video on using macros to increase the size of the PIP windows. That was a huge win as I could stream the live results of the go kart race while switching between the two wireless cameras I had around the track.

[@ProCopyAustralia1]

Thanks for answering my questions Alex. Great tech review of these units

[@cesarhilario09]

amaizing thank you for the info. I want to transmit live events. Actually already do but I find this more reliable. I will most likely get a set to try them out.

[@HarrisonKarlWatson]

Really good review Alex. Nailed every factor. thanks

[@MDARLtd]

Thanks. That's a really useful explanation. I'm looking for a simple solution for an audience view roving camera, this bit of kit could get perfect.

[@I_am_Divine]

Great review. Do they take multiple cameras or you need multiple units for that.

[@bloemkoolproductions2515]

thanks for the video, just ordered a set !!

[@hishamzireeni8932]

that's a great video and test Alex. it is a good idea to use it for wireless video feed into ATEM Mini, but it will be costly and expensive, though very convenient to have. I hope Hollyland gives some good discounts!

[@zhangakairo2468]

Hi Hisham, This is Akairo from Hollyland. I want to know how you want to use this product. You can contact me by email. My Email : [e-mail]

[@yohannsphotographyvideogra9542]

Great review can we do a whole session about Holland 300 pro extended and how to connect with the stream bridge by black magic in a live production in remote hall

[@glencharleslopez311]

I got my hands on a unit briefly. I plugged both HDMI and SDI connections to my ATEM Television Studio HD and the SDI connection seemed to have less latency than the HDMI. If you have time, maybe you can test it out? By the way, thanks for this video!

[@NosratATarighi]

You are the best. Thanks!

[@alvinburrell]

One power adapter makes sense - whats the point of a transmitter that is tethered to the mains. I'm using the older 300 model, works great.

[@AlleghanyJournal]

Great review!

[@Kapstadtarniii]

Thanks for the review. Have you gotten your hands on the 400S Pro yet?

[@yymediaprod]

Great tutorial, I've brought this device but for some reason I can't pair them. Is there a solution or a method to pair it? Everything else works fine.

[@Daashia]

Thank you , really appreciate your videos. how long do these batteries last?

[@richardlouis-pierre8607]

This was a great vid. Can you go out from the ATEM mini pro USBC webcam output into the Hollyland Mars 400S?

[@ArtTistic]

Hello Alex! Love the channel, great content and great production value. Can you tell me if the Atem Mini Pro ISO recording from the Hollyland receiver is clean enough for a finished edit? Thanks for your insight!

[@adamcripps1]

Hi Alex Great review - thanks. Would be interested to know the actual range that can be achieved before the image breaks up. Also you mentioned that you can improve the latency through changing the settings - how much does it improve by?

[@KevinFedde]

Great video! I'm still kind of concerned about audio latency in the ATEM Mini Pro when compared with the wireless HDMI. I have found that I need about 5 frames of audio latency to match the HDMI latency coming from my Panasonic cameras (GH5/GH5s/G9) so if this has more overall latency when compared to audio that might hit the 8-frame limit on the ATEM. Any way you could check that?

[@EasyyokeFilms]

Just buy an audio delay unit. Beringher Shark FBQ100 on amazon. It is $100 and gives you the opportunity to delay for as many frames as you like

[@kduane1]

If you could send wireless audio to the camera...wouldn't that nullify any latency issues, although if you are switching you might notice the signal "catch-up?"

[@RuneHagestrand]

Thanks for a great review. Would your recommend the Mars400S system for a 3 cam live concert streaming to an outdoor P6 Led screen? Or do I have to go for the more expensive Cosmo 600 system? I am pretty new at this and would connect all 3 cameras to the Blackmagic Atem Mini Pro Iso. Since I will also have to buy 3 new cameras, which ones will you recommend in the mid price range? Best regards, Rune H. from Norway.

[@Wizardvz]

Great review on the Mars 400S. I have a question about distance, it always talks about being in line of site, but how about when you can't or don't want to use it that way. Do you think it will work when the Tx and the Rx are a floor apart? Roughly the Rx will be 1 floor below the Tx about 75ft actual distance and the Rx is below where the ceiling is covered with the old stamped metal sheeting that was popular about 75 years ago?? Any help here would be great. Keep up the great work. Thanks.

[@BMSwebbTV]

Hi Alex. Great test as usual of the wireless hdmi transmitter and receiver. I Will bring back to the issues regarding grafics. I am using the mini Pro for live streaming. And i need a better solution for insert messaurses in the program. Ex. Names and text and animations. Ex. trailers. I saw jour demo of singular sw But it is too expensiv. Can we use Adobe after effekt as an alternativ. How can we transfer the output animation to mini Pro? Best regards Thomas.

[@sonydj23]

Hi Garret great video! Thank you so much. Quick question, are you able stream with a Panasonic Camera directly to the transmitter as well as iPhones wirelessly back to the receiver connected to the ATEM mini pro and be able to function as two cameras when you switch cameras on the ATEM? And function that same way through OBS As well? If that makes sense...

[@francofilms5909]

Hi man... nice review.... Im wondering if.... the holllyland 400s could be attached at the atem mini pro for streaming

[@EagleVisionTV]

Very good reviews.. I've been looking at this for a long time but I can worried about the latency as I record music and deley can become obvious would you still recommend it? How long does the battery last?

[@NotAnotherRentalCo]

Thanks Alex! I have a Teradek 500 XT and that doesn't seem to work with the Atem Mini Pro ISO -- any ideas why!?

[@bens1058]

I'd be curious to hear an answer to this! The teradeck ace should near 0 latency, right? But as a work around I'd try an HDMI splitter with EDID override or emulation. I have one of those splitting my PC monitor and feeding the duplicate output to the Atem Mini working great.

[@lyhormom2547]

Can the device set up on multiple cameras? I'm setting up a small show and is looking for wireless solution monitoring....

[@eaglevisionpro_07]

When you channel scan, does the Transmitter have to be on??

[@MemphisGhostHunters]

What about multiple cameras?

[@johnnythunder8382]

hello mr Undone. I don't know if you will ever see this message but i have a serious connection issue i am trying to peice together. I cannot afford a teradek so I am looking at the 300 mar or the 400 mars. if i get the 400 mars i can connect the ninja v to it and have sdi output from the reciever, but if i dont get the 400s and get the 300 i would get a blackmagic sdi converter and use that (3000) as the transmitter. what makes the most sense. the sdi Blackmagic Design HDMI to SDI 6G Mini Converter priced at $145 and the 300 pro$422. verses the $569 for the 400s

[@sportbootcamp5213]

Hi, What do you suggest to use as hardware and software configuration for a video review system in sports? We need at least 4 cameras placed in a different spots of a 400 m stadium and to record all of them at the same time. If there is a call from a referee we need to be able to go back with a footage up to the point requested and demonstrate what we have on different cameras for that particular moment.

[@sreynolds777]

Thank you for your great reviews and tutorials. Two questions. 1. What kind of distance can you get? 2. You mentioned loss of tally light. Since transmission is uni-directional, is there a loss of the Black Magic Mini Pro software camera control also? Thanks

[@HeribertoReynoso]

@Hollyland Oz how much more and which do that? I need me a system like that

[@TexasTint_Pro]

Question how does it work with GoPro? Let me know ASAP plz

[@outDood705]

hello, good job thank you. One question, I just bought the 400s and when i turn them on in the Receiver I get this message. SISTEM EXCEPTION ERROR CODE 2. and it has no signal, is there isomething else that I have to do to make them work> thank you very much in advance

[@AlexPettitt]

Can’t say I’ve ever heard or seen this error message before! I would try to get in contact with Hollyland but it does sound like you may have a dead unit :/

[@jkpinpdx]

My Canon 80D’s back screen blacks out when using my 400s units. Am I missing a step? Is there a setting I need to set on my camera to be able to see my back screen while using these? Please help! I love these, but I must be missing a step!🙏🏽

[@thomaspoelling2022]

Great video, Alex. Do you know if it is possible to hook up the HDMI output of the ATEM Mini into the Hollyland?

[@AlexPettitt]

Yes it is :) That will work fine :)

[@kolapoolakonu2269]

Hello Alex, Thank for the review of Hollyland Mars 300 Pro. I just bought 2 pairs of the enhanced and the output to my Atem Extreme video switcher shows green on one of the wireless trans/receiver. I was able to correct the video output my Sony camera to 1080i/480i and it fixed green screen issue on that camera, the other Sony camera (a different model) did not correct the issue after setting video out to 1080i/480i. can you or anyone assist with this please? thanks

[@edwardwhite4790]

I was able to build the ATEM 810 mobile case keloid who created the concept created. I have the Mobil case on a light stand. Do you know of A laptop tray which connect to a tripod. Or attach to a articulating arm

[@ruwan.sekerauk.5478]

Hi. Alex. it's okay without tally and I don't need camera audio also , but could you please let me know can I use that wireless audio link to communicate with the cameraman. One way is more than enough from switcher to camera operator. can you explain if you dont mind.

[@bournvilleman]

Hi Alex can you recommend a setup for wireless live situations where my camera the Blackmagic 4k can be free to move such as for weddings. I have a Blackmagic mini Pro and I have the Hollyland mars 400s., And wonder waht other equipment would be good to get. Thanks

[@AndrewLumsden]

Can the transmitter be battery powered & receiver through the mains adapter? Or indeed batteries at both Tx & Rx?

[@ShaneBauer7877]

I know this video is two months old but here's my question...wireless rig- if your camera its self has a hmdi and a sdi out can you hook up a monitor on the rig and a sdi to the 400 so the camera operator can view the feed from the camera as well as the feed can go wirelessly back to the Atem Mini Pro

[@calvinengel3830]

That should depend on the camera. If it's capable of sending a signal to both the SDI and HDMI simultaneously I don't see why it wouldn't work.

[@ShaneBauer7877]

@@calvinengel3830 thank you

[@luluvi3282]

Can we use this with webcam or multiple webcam for direct input in obs?

[@Joeysukhdeo]

So is it safe to say I can use only the TS unit and capture through wifi capable switchers?

Hi my name is Glenn I'm a producer. I would like to use 4 video transmission systems simultaneously for live performances with the Atem mini pro from blackmagic. Is it possible? if yes, will there be any interference? And what thirty year old video systems do you buy?

Do u actually use the equipment for anything or just KZbin review videos?

Yep use it all the time. Most recently I've been using these on set to send a feed from my ATEM Mini to a TV in another room, for clients to monitor the output. Works great!

[@Aaron_Smith_OM]

Hi there. How's it for focus pulling? Is the latency low enough that a focus puller can use it on set?

[@AlexPettitt]

Latency is only a few frames, so personally id say it shouldn’t effect a focus puller..but must admit I’ve never tried it myself :)

[@Aaron_Smith_OM]
