I realize you rushed to get this out and thanks for doing that. I realized I could buy 2 of the River 2 for the price of 1 APC 1500VA 900W UPS (with a paltry 11 minute run time). I paid $323 this time last year for a APC BR1500M2!! So even if it's smaller less output, what's not to like! And I dare say, I only really need them to be UPS's so they're not likely to ever really see a full discharge cycle. Maybe 10 minutes before our house generator comes on. Thanks Doug! 👍
When you unplugged the Delta 2 at 8:39 ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Vhimfk4-fgM.html did your fly pack fully reboot? It seems it did not stay up like it did in the other examples.As others have pointed out I could put a UPS past the ecoflow to have the fail over and then the long running time of the eco flow.
In this case, it did. I rushed through setting it up to get this video out quickly and I think I didn't have something setup right on the Ecoflow. Every time I've done it in testing it hasn't caused the reboot.
Love the EcoFlow. I have the River 2 and use it for Live Streaming outside events. When you connect with the Solar Panel for your EcoFlow, you have all the power you need.
Does your Xantrex inverter and battery work better or about the same as one of these EcoFlow or Anker units? Can you run your truck off just the Xantrex inverter and battery? How long would it last? I'm looking into a small production truck with 4 cameras, switcher, audio board, monitors and V-Mix replay and wonder about running all this off the Xantrex & battery power or an EcoFlow for an entire Football Game or Baseball game. Do you think this would work? Love your videos and information. Thanks.
The three 12V 75Ah AGM batteries I have in the trailer will run it (just the electronics) for about 90-100 minutes (without the solar panels making any contribution). That setup cost about $1300. The same run time in an EcoFlow, depending on what sales are going on, would be over $1500, likely well over. And I'd still have to figure out a solution to power all of the 12 Volt devices. (All of the lighting, SDI/HDMI converters, quite a few of the computers and monitors run natively on 12V). That system doesn't power the air conditioner, though... which is needed to keep the equipment (and crew) from misbehaving. After the AGM batteries wear out I'll be replacing them with LFP, which will give me more capacity at a lighter weight. But so far the existing batteries are still going strong. I would have liked to have gone with LFP out of the gate, but when I built the trailer the cost difference was about 5:1. Getting a battery setup that can go for the 5+ hours needed to run a sporting event will get costly pretty quickly. A generator is likely a much more feasible solution.
Thanks. To be honest, Blackmagic devices are not specially power efficient. For instance, the URSA broadcast camera eats battery very fast. Again, you get what you pay for.
The Delta Pro Ultra could power your trailer. Your trailer with a cellular or satellite up-link can do remote production any where with no location/facility infrastructure required. No negotiating for an AC outlet or internet connection. BTW 1800 watts at 120 volts is 15 amps.
Not for very long. Not only do I have to run the electronics (at about 1800 Watts), I also have to run the air conditioner (also about 1800 Watts) to offset the heat created by the electronics and people inside, not to mention the sun. So the base 6 kWh Pro Ulta wouldn't even last two hours. Yeah, you could add additional batteries, but it gets to the point where you'd need a second trailer just to haul the batteries. And then you've spent a fortune, have a ton of extra weight, and still have a fixed capacity. Once the batteries are depleted you've got no recourse to create power after that. I've got a portable 10,000 Watt generator on the way. 10 gallons of fuel will run all day and then some. And if I run low, a trip to the nearest gas station takes care of it pretty easily. As ugly as it can be to have to run off of gasoline (or Diesel), batteries don't have anywhere near the same energy density yet.
Great tips on the EcoFlow! I bought into the EGO Power+ system three years ago, and it's served me well through several extended power outages, as well as running camera and lighting gear in the field. The 2000W base unit weighs about 30 lbs and isn't that portable, but it can use up to four hot-swappable EGO 56v batteries in any combination of 5Ah, 7.5Ah, or 10Ah capacities. With battery swapping, you can run it uninterrupted as long as you need. It's not cheap, but there's a 400W portable one-battery inverter that's about $150. What I don't like about the 2000W base inverter is how long it takes to recharge a set of batteries. That forced me to buy additional fast chargers for $100 each. They also make an unfoldable 10K-lumens 4-panel LED area light that can be hung or tripod-mounted. It has no remote control or CRI rating, but it's a diffuse daylight, very flexible and sturdy.
Hey Dan, I always appreciate your videos. How would you recommend getting into the production truck world without working in Sports trucks? For instance do you ever hire freelancers? I work in the live event side of things and would love to transition into something else
I (and most production companies) hire contractors all the time. If you want to get into that world, your best bet is to find a company that does what you want to do and work for them until you have the experience, gear, and contacts to find work to get out on your own. It can be a tough transition, as you don't want to burn any bridges by stealing customers away from anyone.
To keep the benefits of a UPS, I would suggest getting one that is big enough to lasts at least a minute. Then have that plug into the EcoFlow. The smaller UPS will last me minutes but will take 1ms to switch power sources. The EcoFlow will last hours but will take 30ms to switch. If you go [ mains -> ecoflow -> UPS -> flypack ] you can get the benefit of 1ms switching and hours of battery. Crucial in my usage, where my DIT cart has drives plugged in that I don't want to risk 30ms of power outage that might disconnect during a 30ms switch. Bonus if your UPS has a sine wave corrector.
I haven't tried it myself, but I've heard from a number of viewers who have indicated that Speedify doesn't work very well for streaming video. The consensus seems to be that the variable latency across connections is a problem.
She came and worked a job with DJP over the weekend. She was as happy and fun as I've ever seen her! Her work situation has changed a little and there's a good possibility she might start editing videos for the channel again. Whether she appears on camera here again is uncertain, as she does live kind of far away, but who knows...
Hey Doug! Hope you’re able to see this comment. I have a hyper deck studio 12g and I was wondering what codec do you recommend for recording. Im going to use them for 30 minute videos and edit on Final Cut Pro. I mainly want high quality video and audio
Great video. At Uni a few years back learning about this sort of stuff, they talked about "balanced audio" but I never understood what it actually meant. When you explained what the pins in an XLR cable do, it made sense immediately. I don't know about other people but I'm a nerd who sometimes needs to have a full understanding of all the physics and signal processing before I can comprehend what a device is doing, so this was super helpful and I'm looking forward to the next part of the series! Something I would love to learn is how analog audio becomes digital, as in how does it translate to ones and zeroes and does that have something to do with what a bit rate/sample rate is? I assume its the size of the pieces the analog signal gets chopped into which is then converted to a number, but I'd love to know how that happens and what devices mostly use analog vs digital audio.
I will definitely be covering analog vs digital. I want to make sure that I cover the basic concepts of audio first before I get into that. Sort of a layer on top of the other ground work I'm laying here.
Very informative for someone who is entering into AV world and this really visualizes how audio/videos comes together with mixer… this makes so much sense…
It seems that your example was over LAN and not over the internet as Resilio Sync seems to perform similar to Tailscale + NFS + rsync or Tailscale + Syncthing. It is actually slower than using Tailscale + NFS + FreeFileSync.
A lot of factors go into what kind of performance you'll get. But that doesn't matter so much, as I'll get to in a moment. While a portion of the demo I did was over the LAN, going over the Internet doesn't necessarily mean it's going to be that much slower. I've had quite a few times where files will sync over the public Internet at the full 110+ MB/sec available with my Internet connection. It, of course, depends on the available bandwidth between endpoints with every solution out there. Resilio will establish a direct connection whenever it possibly can (basically assuming the ISP and router will permit it), and when it is able, it will go at full wire speed -- literally as fast as is possible. Both solutions are efficient at identifying changed portions of files and only synchronizing what is different. There isn't really a huge advantage of one over the other there. The biggest difference between them is the complexity at setting them up and getting them going. It's hard to justify asking someone who isn't technology-focused to setup something like Tailscale and rsync or FreeFileSync. But asking someone to install and get Resilio Sync up and going isn't really much of a challenge, as it is just a single application and you can literally share just a single URL. They can click the URL you share, and that will install the software and walk them through getting that shared folder up and going. To ask someone who isn't really technology savvy to install a VPN, then install rsync or FreeFileSync is usually asking too much. I would never ask my clients to do something like that, which is the problem that this video is focused on helping my viewers to solve.
Hello Doug from Greece! I have an atem constellation 2me hd switcher. I stream with my Magewell Ultra Stream SDI encoder. I have a problem, and I hope you to help me figure it out when I stream stereo sources. When stereo sound passing through the camera (sdi cable) everything is fine. When stereo sound passing through TRS analog audio jacks sound seems to have phasing effect. Music sounds weird and in microphones canceling everything. Do you had ever in the past same problem? From the headphones I hear everything perfect, and the recording as well. Only in livestream I have problem. I checked in RU-vid platform not other platform. Because you starting a series of video dealing with audio if you thing is something that is related to, please mention if to a future video. Dimitris A fun of you. PS Hope it makes sense my problem to you, because I don't know English very well. But I understand you very well in your videos.
Those are the exact symptoms of having an unbalanced, stereo audio source being plugged into a monaural balanced input. An incompatibility between balanced and unbalanced connections. As demonstrated in the video, the audio that the switcher "hears" on its input is the *difference* between the signal on tip and ring of the connected cable. If the connected source is stereo (rather than balanced), that device is putting the left audio channel on the tip and the right audio channel on the ring. So at the input, the switcher is getting the left channel where it's expecting the hot (+) side and right channel where it's expecting tthe cold (-) side of a balanced signal. Since the audio that the switcher hears is the difference between what is on the left vs right channel, you only hear sounds that are either in the left or right channel, but anything in both gets cancelled out and removed. That, and everything that does come through from the right channel has its phase inverted, creating a weird spacious, behind- or above-you rather than distinct in-front-of-you sound. The fix is to use the right cable. If you have a stereo unbalanced source that you want to connect to balanced audio inputs, you need a cable that splits the signal into two separate wires -- one for the left, and one for the right. So one end of the cable would have a TRS (or mini TRS) for stereo and the other end of the cable would have two TS connectors to split that into left and right. Something like this: amzn.to/45MSQ8M If you're already using an insert cable and still have the problem, that's a sign that the ground (sleeve) connection is broken and the cable needs to be repaired or replaced.
A shame that the video does not rank good. Seams RU-vid mimics the reality. I personally did Trainings on audio (specifically on XLR and its advantages) cause there were problems in using wrong adapters. Spend hours to make it vivid. Nobody listened „that boring lesson“ and it was like before. Adapters were build to adapt XLR to 3,5 and „left“ was recorded hot and „right“ was recorded cold 😂😂😂 sound quality in the school hall after cutting and no additional audio processing was amazingly bad. It was the time were we using macrosystems Casablanca 😎🤪 It’s so cool to watch the beauty of symmetrical signals live on your software. Can we get this peace of art?
Wondering if the Mac Studio prefers the DP alt mode HDMI cable to its HDMI port? I can get all my displays set up, then reboot, and some seemingly random display ends up with the primary display. It _seems_ to usually be the SIIG connection, which of course goes some place totally inconvenient.
Hi, Doug. Unfortunately not always a great video performs well. This is really educational even if people know some about sound. The software you created is really complete and seems very ready for the purpose. I run a school in Portugal where we teach video and sound, and would be very happy if you could let us use it. If not, thanks anyway.
Hey Dough, Love your video great details, and very informative as usual! Does the ASUS ProArt Display PA278CV 27" 16:9 Adaptive-Sync QHD IPS Monitor and the ASUS ProArt Display PA278CV 27" 16:9 Adaptive-Sync QHD IPS Monitor models have the same features as the 24” you mentioned? Just in a large size, and with one model with HDR?
Hey there, Quick question : I'm using an old Panasonic wj-mx12 for vjing. That convertor seems to not receive any signal from the device, nor sending it :( any idea why ? Thank you for your video
The WJ-MX12 is an analog, standard definition switcher. It takes (and creates) analog composite, standard definition video. SDI is a digital signal, and these days is nearly always high definition. The two signals are very different and are not compatible. If you are wanting to send the output of your switcher to an HDMI display, you can get a component to HDMI converter (like amzn.to/4cDJYo2) along with an RCA to BNC adapter/cable. If you have an HDMI source that you want to get into your switcher, an HDMI to composite converter (like amzn.to/3VXEPBX) will do that. But more than likely an HDMI source is going to be high definition, so you'll experience pretty significant loss of detail going through the conversion. And you might have to watch out for differences in frame rate. The WJ-MX12 is only going to be capable of either 25 or 30 frames per second (depending on what region it was made for).
@@djp_video Thank you for your answer ! I already have those little converters and wanted to upgrade to something better 😅I guess I'll send back the product and keep digging the topic. Best,
⚠ Extremely basic question alert!!⚠ Why, in simple terms, would I actually *need* one of these devices, rather than running a live stream via YT (or whatever) straight over my internet connection? A bit of context: I am a teacher running weekly classes over Zoom. A few students' internet connections are occasionally poor, such that they have to disconnect, and reconnect. Occasionally, they miss the session completely and catch up by watching a recording. Would one of these reduce these kinds of occurrences? Is this device not simply 'steadying' the connection from the streamer's end? Am I right in thinking it has no bearing at all on the audience end? In summary, how does the Web Presenter improve on a regular live stream over YT?
These are designed to get video from a video production system out to a streaming site. If you already have a solution for getting video to a site like RU-vid, you don't need it. This is for people who want to use a piece of hardware to stream instead of doing it through a piece of software running on a computer. It does not help with issues on the viewer's end.
