Hollyland Mars 300 Pro for Livestreaming

[@SFbayArea94121]

Man you’ve taught me so much in this whole drone videography thing. Just wanted to say a huge thanks that there’s people like you out there. You haven’t posted in a while so I hope things are going well. But again a huge thanks. Your shots are incredible and have been an inspiration to me for sure but I wouldn’t doubt many people like me. I know a decent bit about camera 📸 photography but you helped me learn a great deal about drone photography with your videos

[@dariyal]

This is great… I would love to see a video tutorial on how to actually set up and film a live-streaming event with this

[@tangibleplanetvisualmedia1138]

Man so glad I found this. I wanted this see this exact test of mixing this with a wired source. Really happy this should work together since there doesn't seem to be any kind of HDMI delay box

[@TheVictoriousKicks]

What’s the piece you had attached to the gimbal where you put the transmitter

[@AdamTroup]

Incredibly helpful, the latency audio sync issues when mixing with wired cameras are what I was interested in and putting the audio between both sources to balance it was what I immediately thought of - and then you did it! Great minds ;) Super helpful video!

[@mondotv4216]

Explain it to me? The ATEM mini pro only has one audio delay and then only for the direct input. Assuming you’re using wireless mics through either a camera or directly into the ATEM, the wireless video is always going to be out of sync and 4 frames is significant. You can see in the example clip it looks off. That kind if compromise means nothing is in sync.

[@JaredSpink]

@@mondotv4216 I was wondering the same.

[@OvertakingLane]

Thanks for the review, I am looking at these to use for a budget multi wireless cameras into the atem mini for car racing. Look forward to seeing some more reviews on live streaming

[@districtposhanchd3545]

Hi thanks, can you please guide if this device work with capture card to provide live view in my laptop??

[@coachcarl535]

My concern would be live streaming sports, CAM1-wired main camera. CAM2 -wireless, connected to a switcher like Rgblink & broadcasting through a mixer. Would there be latency on the wireless CAM2 focusing on the goalie as an example.

[@joseflores6207]

What camera should I use for this transmitter? I have a small live streaming channel? And I just bought the yolo box pro, and this transmitter? But no camera yet and I need it soon!!?? Thanks

[@itapmedia]

Great review…buying it asap

[@MikeOstrovljanovic]

Hi thanks for this video. just one question. do you use it a wireless connected cam with wired cams on ATEM? if yes how you sync the wireless one with the wired ones specifically if you get the sound from external mixer! like it is often with church related productions.

[@BlueMantleFilms]

I do talk about that specifically in the video. Guessing you didn’t watch the whole thing?

[@BlueMantleFilms]

In short, yes I do combine wireless and wired sources, and I add an audio delay that splits the difference between the two sources and they end up close to in sync with the audio and with each other (not perfect, but close).

[@jeanettewilkinson8076]

What gimbal are you using?

[@stegokitty]

A fabulous, thoughtful review.

[@superiorstreaming7350]

Can you tell me what all the tools in the app actually do. They don't seem to make any changes to the output image and there doesn't seem to be any way to change the image like histogram and vectorscope. Sharpness changes on the monitor but doesn't make it to the hdmi output.

[@stewdun2426]

Great vid, very informative and professionaly executed.

[@BlueMantleFilms]

Thanks! I'm hoping to continue making review videos. Certainly I still want to make the drone and travel films, and those are the ones that I really enjoy making, but it's nice to mix things up occasionally with a different type of video.

[@Chrisreedbeats]

YES! This was the video I needed! THANK YOU. Question: When would someone consider upgrading from this to the much more expensive $650 updated version of this device?

[@frankvalen2147]

Can I plug the transmitter and receiver directly to the socket for power instead of using battery.

[@NoelDelPilar]

Great video, thank you so much! I order the Hollyland Mars 300 Pro Enhanced and waitign for the second kit. One question, how do you livestrean a weddng that includes ceremony and then later the reception? Do you need to do two different schedule events in KZbin?

[@linvol20]

Hi, what would you recomened as a higher quality monitor transmitter/receiver? Thank you.

[@GlassfilmWeddings]

how to you delay the audio by frames?

[@jamesabke5851]

Great job. Thanks for your hard work...

[@djdavidbraz]

I thinking about getting this to live stream weddings for my clients…would this work well for this application in your opinion?

[@davo0593]

Hi. Amazing Video. Just a question. Where do you add that delay in audio to sync with video?

[@BlueMantleFilms]

I have a Zoom F6 audio recorder that I use to manage audio for my livestreams, so that's what I use. The ATEM Mini can do an 8-frame delay, so not *quite* enough for what I prefer (I do around 300ms/9 frames delay). 8 is pretty close, though, so if you're working with an ATEM it could work, depending on how particular you are about syncing. An 8-frame delay would get pretty close to the ideal delay.

[@reddanselmo8781]

Can adjust the audio delay from the mic input to match the video feed’s latency?

[@BlueMantleFilms]

With the ATEM Mini (which has up to 8 frames delay with the software control) it gets close. What's tricky is the HDMI on my cameras have about 5 frames of latency, so I've got to add that to the latency of the wireless system (around 4 frames) so ideally I'd do a 9-frame delay. For myself this isn't a problem because I have hardware that can do the delay, but if I were limited to using only the ATEM for the delay, the max delay at 8 frames would be *slightly* off.

[@ybgaming07]

Great review, I was plan to buy this for the multicam livestream with atem too and the price 300pro is better than 400s for new like me. Thanks sir

[@BrodiBarringer]

Any idea how to remove the grid?.. I can’t ..

[@michaelcanagasabey297]

Excellent review. I use Roland switcher with 4 hdmi input and how many Mars 300pro can I use in this system?

[@BlueMantleFilms]

I've used 2 simultaneously. The first time I did that I had the receivers too close together, and they were interfering with each other, but since then I've put the receivers farther apart (at least 3 feet) and it has worked. I also recently got the Mars 400S Pro, so I want to do a video about using all three together.

[@michaelcanagasabey297]

@@BlueMantleFilms Thank you for the information. Happy New Year to you and your loved ones.

[@akhilraithatha2951]

Hey thanks for the video, super useful. Do you know if you can use multiple sets at the same time? I.e. 2 transmitters with 2 receivers?

[@kingsleyanyanwu5915]

How do i set it up on my laptop 💻

[@vladislavrezanov5784]

Hi! Thank you for good review! Could you please answer if I could use that transmitter-receiver equipment for the following combination: 1. hdmi wired on-cam monitor for operator 2. wireless receiver on monitor (not tablet/smartphone, but real monitor) for focus-puller/director 3. tablet/smartphone for customer. Will this equipment give that option to work with all 3 at the same time?

[@SoloTraceur]

Yes, you can simultaneously connect two smart devices via wifi while the receiver is connected to a monitor

[@Yosuuu_]

I have a problem with latency for my streaming production, it wont synch to audio, i try to match from the mixer audio but never match... Any solution for this?

[@MKHL]

use a slate for a shot, it'll give you the exact offset timing and then you can replicate that throughout your production

[@robertbernal9818]

I'm having alot of issues with my pro 300 enhanced I'm like 10-15 feet from my truck that's were my transmitter Sits. but I'm getting lag and that choppy pixlation stuff. I'm fairly new to all this. I Live Stream Chasing Police Scanner Calls. so I'm all over town. so I can't always be right by my Truck. but I'm trying to update the firmware threw the Google play store. and it's not letting me so idk if that's the issue. that I need to update I'm nit sure any info is much appreciated

[@BlueMantleFilms]

I'll bet the truck itself is causing issues. I learned this the hard way: I was doing a mobile livestream, and had two receivers in the back of a van (with the back doors open), with two cameramen and their respective cameras/transmitters out on the route that was being walked. I couldn't get a clean signal from either camera regardless of how close they were, and I think it was because the signals were bouncing around inside the van. The next livestream I did, I mounted the receivers high on poles, and kept them farther apart from each other (6-ish feet) and it worked really well.

[@enidrajm]

How are you attaching the Mars 300 Pro to the monitor? I can't seem to find a double-sided NPF battery.

[@BlueMantleFilms]

The monitor is a Feelworld 5-inch monitor that has a mount that’s the same as an NPF battery, so the Mars 300 mounts onto the monitor as though the monitor itself is the battery. And then on the other side of the monitor there’s a spot for an NPF battery, so the battery that you put into that powers both the monitor and transmitter.

[@enidrajm]

@@BlueMantleFilms I see. It's a feature of that particular monitor. I appreciate your response. : ) And thanks for the inspiration for the combo handle-monitor mount. I'm considering it along a NATO approach.

[@enidrajm]

Oh, I'm also doing a livestream setup and the Hollyland is aaaawesome. I was using the Zhiyun system before and it is doesn't even compare to the video quality out of the Mars 300 Pro.

[@lingmesseroriginalchannel]

Hey there, so I'm curiosu have you been able to adjust the latency in the Atem software?

[@BlueMantleFilms]

Yep, up to an 8-frame delay. I've done that a couple of times, but usually I use an external audio recorder (Zoom F6) to do audio delay because I prefer about 300ms (9-frame) delay.

[@lingmesseroriginalchannel]

@@BlueMantleFilms thanks so much for the quick reply! I shall also run my audio through my cameras as well, have you tried doing that through the holly land as well?

[@jeffstevenson9406]

What is the HDMI quality when used to livestream? Lumix G7 outputs 4k HDMI at least at 100 Mbps bitrate and the Mars 400 Pro only does 12 Mbps. Here's my use case: - Livestreaming high school sports - Lumix G7 HDMI output either 1080p or 4k - Elgato Camlink 4k - OBS - Stream to KZbin at 13-20 Mbps I'm trying to get that sweet high-quality HDMI output all the way in to OBS

[@Moiostrovstudio]

thanks for a great test :)

[@fireislandmavic5939]

thank you for the review

[@BlueMantleFilms]

You're welcome! I know the product is a bit niche, but hopefully the video can help out those who are looking into wireless video devices. :-)

[@OruphotoChennai]

Does this output both SDI and HDMI at the same time?

[@BlueMantleFilms]

There are no SDI plugs on this one. The Mars 400s has SDI.

[@bennozwanenburg9318]

Hi, I own the 300 Pro but having problems with audio/video out of sync. Audio comes half a second later than video when you use the app on iPad/iPhone. Hollyland says I'm the only one with this problem and they can't reproduce it so they don't help me. Can you please check this out with your device and see if you're having the same problems? Thanks!

[@BlueMantleFilms]

I haven’t had sync issues on either of mine. Are you sending audio through the camera itself? Any other devices that the audio is going through?

[@bennozwanenburg9318]

When I play a sync test video from any source and whatch it by the app than audio is half a second too late. When I connect a monitor at the output of my 300 Pro then it’s perfect in sync. The problem is the app. Is it perfect in sync with your iPad/iPhone?

[@benaeventos1149]

Best review

[@journeyNature]

amazing helpful thanks❤️

[@Dracken09]

Could you talk about how you live stream with it though?

[@BlueMantleFilms]

If you mean as a livestreaming device itself, it’s not capable of doing that. My streaming device is an ATEM Mini Pro. So all of my video sources, wireless and wired, go into the ATEM, then I’m able to do live switching between the various angles, and use the built-in encoder to stream directly to KZbin or Facebook (or other platforms).

[@neoray10]

Which spiral micro hdmi cable was that ?

[@BlueMantleFilms]

It's the Atomos AtomFlex HDMI. It's definitely not the cheapest option for spiral cables (around $60), but it's rated to be able to send 4K at 60fps at 4:2:2 compression, so I can use it with my Atomos Ninja V to record with as little compression as possible. For livestreaming, which for my setup with the ATEM Mini Pro is limited to 1080p, this cable is overkill. Still, since I have it, I use it for my livestream setup also.

[@BlueMantleFilms]

Also, the one I have is not micro HDMI, it's standard (Type A) HDMI on both ends. But they do have Micro-HDMI and Mini-HDMI options.

[@neoray10]

@@BlueMantleFilms aah I see , yea that way it makes more sense. I am looking for a few adorable solutions on Ali express for that cable

[@neoray10]

@@BlueMantleFilms thank you , I wondered why is that cable that expensive but it makes sense for your use.
