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.

@@mondotv4216 I was wondering the same.

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.

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. :-)

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.

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

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.

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.

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

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

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).

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.

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

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 KZfaq or Facebook (or other platforms).

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

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?

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?

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.

@@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.

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.

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.

@@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?

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.

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.

@@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

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