How to power the receiver and the transmitter with power bank? How much power does it need? How long do they last? Which external battery do they require and support? Can I use the Panasonic x2 battery maybe with an adapter from Sony battery? Thank you
5V/2A. It is not recommended to use a power bank because the current decreases as the voltage drops after using the power bank. We only recommend NPF batteries for use. You can use V/G mount batteries and then convert D-Tap to DC for power supply. This way, the usage time will be extended.
Hello, perhaps you could help me with a problem. The transmitter always times to the "NO VIDEO". The HDMI connection of the camera is OK and sends the signal. The HDMI cable has been replaced and still no signal is emitted from the transmitter. What else could I do?
Hi guys! I 'm a wildlife videographer, and wonder if it's possible to start/stop video recording on remote, using your transmitter? It'd also be great to control the camera settings remotely, but most important is just to start/stop recording. Does it work this way? Thx!
Hi there, most power banks cannot stabilize the output power when the battery is low, so it is not recommended to use power banks for power supply in professional scenarios
I have 3 of these and they work really nicely! One thing I haven't tried but want to ask about, the SDI loop out on the Tx unit, will that only output from the SDI in, or can it also be used to output the HDMI in signal? Would really appreciate if anyone has tried this.
I believe it’s passthrough HDMI In to SDI Out, very handy to go through the transmitter and Out via SDI to an external monitor on your camera, less latency! 🔥 tho to be confirmed!
Hi when I try to pair it the reciever is saying starting but it doesn't show the pairing option in the screen but the transmitter works fine pls guide on how to fix this
what's the difference between the 2 types antennas that are supplied with the kit? and what would be the best config to mount the receiver. does it matter if u hang the receiver upside down?
Triumph Antenna(2.5dBi) Cylindrical Antenna(2dBi) Mushroom Antenna(5dBi) Lollipop Antenna(2.5 dBi) Soft Antenna(4 dBi Antenna) Those antennas have different gains and different transmission directions. It's worth noting that the mushroom is an omnidirectional circularly-polarized antenna. It fits the application scenarios where there is a noticeable difference in height between the transmitter and receiver. For the 2nd question, it actually depends on what antennas you use. It matters if you use triumph, mushroom, capsule, and lollipop antennas, while it doesn't matter when using soft and cylindrical antennas as long as the RX is set high enough.

@@hollylandtech Do you understand what I mean? I said set up for focus puller and director's monitor wirelessly at the same time like your promo video, not "focus the puller and director"
when will there be a software update for it to make 1080i 59.94? I bought 6 devices and I can't use it that only makes 1080i 60 and the previous model I have makes 1080i 59.94. this device for being superior should make 59.94

@@hollylandtechso the receivers have to be 2m meters away from each other? I use two sets for sports. One set works great but the second set will flicker black screen intermittent. Both receivers are about two feet from each other by my Atem switcher
@@SCRCast Yes that is definitely what i am asking. Its like we can not use the same video capture card model as the computer will read it as one capture card. Is it the same with Cosmo C1?
@@SCRCast It looks more like a black screen caused by interference. Does the screen display the Hollyland logo and prompt for linking? You can try scanning and switching to a frequency channel with less interference. The frequency channel between two sets of devices should be set at least 2 channels apart In addition, the antenna should be installed vertically, with the RX at least 1.7 meters above the ground and ensure that there are no obstacles between each set of RX and TX
I own the device, but there is a noticable lag between the video and the audio. The video comes first and the audio follows is with a delay which is weird. Normally audio travels faster.
Hello! Thank you for your feedback and we are so sorry for your unpleasant experience. We noticed there are some compatibility problems between COSMO C1 and Sony FX3 at present that will led to this situation, our product development department has received the feedback and trying the best to fix it.

Hello friend! Yes, you can, please check out our local dealer PixelPitch's website in India: pixelpitch.in/product/hollyland-cosmo-c1-sdi-hdmi-wireless-video-transmission-system/ Hope it can help with your purchase.Cheers!

hi Cosmo doesn't support that function
Thx for the answer! @@hollylandtech
Hello! Can you tell me what power bank can I use for cosmo c1?
Hi there, most power banks cannot stabilize the output power when the battery is low, so it is not recommended to use power banks for power supply in professional scenarios
can the receiver be connected simultaneously to two outputs - one using usb-c to computer and other using hdmi to tv/project?
Awesome!
Thank u for your support!

Have you tried running the 3 or 2 Cosmo C1 at the same time while live streaming? Just wondering if it works on 2 set.
Can this be use with handle Ecamm Live?
what video bitrate does cosmo c1 transmit?
Are u reading from the company webpage?
On the usbc connecting to laptop for Zoom.. Can you control which group is on the audio feed or is it both??
Can I use two receiver from one transmitter?
Yes
Hey! Are you able to connect multiple receivers to 1 transmitter?
Hi when I try to pair it the reciever is saying starting but it doesn't show the pairing option in the screen but the transmitter works fine pls guide on how to fix this
I cant seem to use UVC on a macbook with google meet? : Edit, fixed - had to set the camera to 720p :)
Seems like a great product! Does the use of UVC demand a specific kind or quality of USB-C to C cable for stability?
Hello， you can use the standard USB-C to C cable for stability.
hi, why doesn't this model make 1080i 59.94 and the competition equipment does?

hollyland second antenna not coming on the display. how do i fix this 400s model
Will the cosmo transmit audio from the camera as well?
sure😃
Hi I’d like to know how to set up for both focus puller and director monitor just like your promo video, it seem like all using wireless receivers
Hi there. The Cosmo C1 can only transmit video signals, and cannot focus the puller and director.

Hey! Do the Cosmos C1s connect to the Hollyland app? I'd love to use these with my 12.9" iPad Pro.
Hi, the Cosmo C1 can not connect Hollyland APP. But Mars 400s pro can do it.
@@hollylandtech Awesome! Thanks for replying!
Can we use 2 sets of Cosmo C1 at the same time while doing Live streaming?
sure, but it is necessary to confirm that the two set are more than 2m apart
@@hollylandtech Thanks. So 2 Cosmo C1 on 2 cameras set 2m apart.

Hello, I notice a very noticeable delay in the feed. Any suggestions on how this can be fixed?
How much was the delay in your case? While the system can reach as low as 40ms, in some cases it does get a bigger lag.
I own the device, but there is a noticable lag between the video and the audio. The video comes first and the audio follows is with a delay which is weird. Normally audio travels faster.
What's your setup?
How many c1 can I run in the same location?
I spent AU$1500 on this but it won’t work properly with my Sony FX3.
Only transmits interlaced!!!
