No, encoding and recording functions are not available while decoding HB.

16.Under what circumstances will color bars be encoded?‌
However, when the encoding mode is set to HX, color bars will be encoded if the SDI input signal is suddenly lost. If no input signal is connected when encoding is started, color bars will not be encoded.

General

1.What the operation result is when Dyna Hub and the touchscreen are used simultaneously?‌
The final result will be based on whichever command Vela received last—there is no priority between the two control methods. The outcome reflects the most recent operation instruction received by Vela.

2.Will switching the decode (or encode) source cause the encode (or decode) output to freeze?‌
Yes—encoding and decoding share the same resource channel. Switching video sources triggers a reallocation of system resources, which temporarily pauses ongoing encode or decode tasks. The tasks will automatically resume after a brief moment; just allow a short waiting period for normal operation to continue.

3.If Vela is simultaneously encoding and decoding, and recording is enabled, which video stream—encoded or decoded—is saved?‌
The recording function only captures and saves the currently encoded video stream.

4.When Vela is simultaneously encoding and decoding, which video and audio—encoded or decoded—is shown on the HDMI output?‌
Both Vela’s screen and HDMI output display the decoded video. If decoding is disabled, they default to showing the encoded video.
The HDMI output priority order is: Media playback > Decode > Encode.

5.Can I remove the SSD immediately after recording ends?‌
No. After recording stops, you must wait for approximately 2 minutes before removing the SSD. Do not unplug it immediately, and avoid attempting to play back the recorded file during this time, as doing so may corrupt the video file.

6.The desktop may become extremely sluggish or even freeze when the C1 SSD enclosure is connected?‌
The C1 SSD enclosure requires external power. If your desktop already has USB devices connected—such as a flash drive, keyboard, or mouse—do not plug the C1 drive into USB ports on the same side of the computer.
For example: if your keyboard and mouse are plugged into the front USB ports, connect the C1 SSD enclosure to the rear USB ports instead.

7.How can I check the recording status?‌
During recording, a timer will appear on Vela’s small screen, counting the elapsed time. You can also view the timer remotely via Dyna Hub.

8.What video formats can Vela create?‌
Vela supports the following video file formats: MOV, TS, and MP4. There is no maximum file size limit—the recording length is only constrained by the available storage capacity of the SSD.

9.Can Vela play back a video and output it via SDI?‌
No. Vela’s SDI OUT is a loop-through output—it can only pass through the video signal received from SDI IN. Video playback from Vela can be output via HDMI or the optical module interface.

10.What should I do if Vela’s small screen shows no image?‌
(1) Connect the source directly to a monitor to confirm it is outputting a valid video signal.
(2) Check the source resolution: Vela currently only supports input resolutions below 4K60. If an unsupported resolution (as listed in the user manual) is used, the screen may display black or blue. Please switch the source to a supported resolution.
(3) Try other supported resolutions: If there’s still no image after changing the resolution, test additional resolutions known to be supported by Vela.
(4) Review decode settings: If the decode is enabled, it will not show the encoded (input) video on the small screen. Disable decode display if you expect to see the live input.
(5) Check HDMI and NDI outputs: If both HDMI and NDI outputs show normal video, but the small screen remains blank, the issue is likely with the TFT screen itself. Try restarting the device.
(6) Restart or restore factory settings: Reboot Vela, or perform a factory reset if necessary.
(7) Contact support: If none of the above steps resolve the issue, please contact your dealer or the manufacturer for firmware updates or repair service.

11.Why can’t Vela playback the recorded video file?‌
(1)Check the file format: Vela simultaneously creates a TS backup file when recording an MP4/MOV file (playable). The TS file cannot be played directly on Vela—please use the MP4 or MOV version for playback.
(2)File corruption: If the device lost power suddenly or froze during recording, the video file may be corrupted. Corrupted files cannot be played back on Vela.
(3)Wait before removing storage: Always wait at least 2 minutes after recording stops before removing the SSD.

12.If audio is input via the 3.5mm audio jack, will it also be output through HDMI?‌
Yes—Vela supports embedding audio from the 3.5mm audio input into the HDMI output. This embedded audio can also be transmitted via NDI or the optical module. When using this feature, please ensure that the audio volume is enabled and properly adjusted in the Vela UI.

Stream

1.Does Vela support streaming to multiple live platforms simultaneously?‌
No, Vela only supports streaming to a single destination at a time.

2.How do I install the NDI plugin for OBS?‌
(1)Make sure NDI Tools is installed on your computer. Download it from: https://ndi.video/tools/
(2)Download and install OBS from its official site: https://obsproject.com/download
(3)Download the OBS NDI plugin.
Get it from: https://github.com/DistroAV/DistroAV/releases/tag/6.1.1
(4)Choose the latest version: On the release page, scroll down to the "Assets" section and download the .exe installer file.
(5)Launch the downloaded .exe file and install it to your OBS installation directory.
(6)After installation, open OBS Studio—you’ll now be able to use NDI sources and outputs via the NDI plugin.

3.How do I stream to Wowza?‌
(1)Open the Wowza Streaming Engine Manager and click "Add New".
(2)Select "Quick Live Stream".
(3)Choose RTMP as the protocol and set the resolution to 1080p.
(4)On the next screen, note the Stream URL (Server URL) and Stream Name provided by Wowza.
(5)In Dyna Hub or on Vela’s touchscreen interface, enter the streaming destination in the format:<Stream URL>/<Stream Name>
(6)Start the stream—once connected, you’ll see a successful live feed in Wowza.

4.How do I stream to Huya (Tiger) Live?‌
(1)Open the Huya Live client, go to "Third-Party Streaming" (or "Custom RTMP").
(2)Retrieve the streaming URL (server address) and stream key (live code) provided by Huya.
(3)In Dyna Hub or on Vela’s touchscreen interface, enter the destination in the format:
<Streaming URL>/<Stream Key>
(4)Start the stream—once connected, your broadcast will go live on Huya.

5.How do I enable the internal streaming server and get the stream address?‌
Switch to Stream Mode via the UI.
Go to the Main Menu and tap Stream Settings.
Select Inner Stream for either RTMP or RTSP.
Configure the encoding parameters.
Toggle the slider to ON and click “Apply” to start streaming.
The system will automatically generate and display the stream address.

6.Why does Vela keep freezing during decoding?‌
When using the Decode (Dec) function, you must select the appropriate decoding mode—HX or HB—in the decode menu to match the format of the incoming NDI stream. If the wrong mode is selected (or none is selected), Vela may fail to decode properly and appear stuck or frozen. Ensure the decode mode matches the source’s NDI encoding type.

Network

1.Why does the network connection indicator on Vela remain red after connecting to a local network?‌
If the local network is connected to the internet: Please be patient—once Vela successfully obtains an IP address via DHCP, the indicator will turn green.
If the local network has no internet access, the indicator will stay red. Wait until the displayed address changes from a MAC address to a valid IP address—that indicates Vela has successfully joined the local network.

2.Does a red network status on Vela mean the network connection is disconnected?‌
No. The red/green indicator on Vela reflects internet connectivity, not local network connectivity:
Green: Vela can successfully reach the internet.
Red: Vela cannot access the internet—but it may still be properly connected to the local network.
In other words, a red status does not mean the device is disconnected from the local network; it only indicates that internet access is unavailable.

3.Can't access the Dyna Hub backend after restoring Vela to factory settings?‌
This issue occurs because the factory reset reverts Vela to an older firmware version that may be incompatible with the current Dyna Hub. We are actively working on a fix.
Temporary workaround:
Add a router into the environment and enable Vela’s DHCP. This will allow Vela to obtain a valid IP address and restore communication with Dyna Hub.
Once accessible, please update Vela to the latest firmware via Dyna Hub.

13.If my computer is connected to two separate LANs via two Ethernet ports, can Dyna Hub discover devices on both networks?

No. In this scenario, Dyna Hub can only detect devices on one of the LANs. However, if your computer is connected to one LAN via Ethernet and simultaneously connected to another network via Wi-Fi, Dyna Hub will be able to discover devices on both networks.

Quick Start

1.How do I use the Merge and Split functions in Dyna View’s custom layout?

To Merge:
Enter the custom layout interface.
Click and hold the left mouse button to select the grid cells you want to merge.
Click "Merge" to combine them into a single area.
To Split:
After merging, if you’re not satisfied with the layout, you can click "Split."
Note: Splitting does not undo only one specific merged area—it restores all previously merged grids back to their original individual cells.

2.Why isn’t the resolution of the NDI signal in Dyna View at its original quality?

To reduce bandwidth usage, NDI signals are automatically displayed at a lower resolution by default.
To restore the original resolution, you can either:
Click "High-Bandwidth Decode" in the top-right corner, or
Double-click the preview window to enlarge it for full-resolution monitoring.

3.What’s the difference between batch recording and individual recording in Dyna View?

Batch Recording (via the button on the right):
When clicked, it simultaneously records all currently active video windows into a single combined file.
Individual Recording:
Records only one selected video stream and saves it as a separate file in the current directory.

4.What network streaming protocols can Dyna View decode?

Dyna View supports decoding the following protocols:
NDI, RTMP, RTSP, SRT, UDP, HLS, FLV, and TS.

5.What cameras does Dyna View support?

Dyna View supports any camera that your computer can recognize, including:
USB cameras
HDMI cameras (require a capture card to connect to the computer)
SDI cameras (require a capture card or video switcher to connect to the computer)
NDI cameras

6.What’s the difference between global volume control and individual video volume control in Dyna View?

Global Volume:
If the global volume is muted or turned off, no audio will be output from any window. You must enable the global volume to hear sound from any source.
Individual Video Volume:
This setting only affects the audio of the specific window it’s applied to and does not impact the audio of other windows.

7.What is the purpose of High-Bandwidth Decoding in Dyna View?

When decoding an NDI stream, if the video is displayed in a small preview window, Dyna View defaults to decoding a lower-resolution proxy stream to save bandwidth and system resources.
Enabling High-Bandwidth Decoding allows Dyna View to fully decode the original high-resolution NDI stream (e.g., 2K or 4K), delivering the best possible image quality.

8.What is the purpose of Dyna View’s screen extension feature?

It allows you to extend the Dyna View monitoring area across multiple displays connected to your computer. The number of supported extended screens depends on the total number of displays your computer has.

9.Does Dyna View support NDI output?

Yes. Dyna View can send out the currently decoded video feeds and window layout as an NDI stream.

10.What is the maximum resolution Dyna View can decode?

Dyna View supports a very wide range of resolutions. As long as your computer’s hardware is capable of decoding it, Dyna View can generally play it back.

11.What resolutions does Dyna View support?

Dyna View supports resolutions ranging from 144p up to 8K and beyond—as long as your computer is capable of decoding them.
Dyna View itself does not impose any resolution limits. The real bottlenecks are typically:
CPU decoding power
GPU hardware decoding capability
Video bitrate
Storage or network speed

12.Can Dyna View decode audio sources with 8 channels or more?

Yes. Dyna View supports decoding audio streams with 8 or more channels, and it also displays the current channel layout.

Quick Start

1.How do I disconnect a signal connection in Dyna Router after it’s been set up?

To remove an existing connection between an input (left side) and an output (right side):
Click the gear icon on the configured signal output.
In the settings panel that appears, uncheck the connected signal input to disconnect it.

2.In Dyna Router, after using the "Enable All Outputs" feature, the first two video channels started playing—but I don’t want the rest to play. How do I stop them?

You can right-click on the output channel to disable playback. Each right-click will stop playback for one subsequent video channel, starting from the next one in sequence. Repeat as needed to cancel playback for additional channels.

4.Does Dyna Router’s matrix functionality place high demands on computer performance?

No. Dyna Router simply renames and re-routes existing NDI streams within the network—it doesn’t perform any additional processing, transcoding, or decoding. Since it doesn't decode video itself, the decoding endpoints (e.g., viewers or receivers) handle all playback, and Dyna Router imposes virtually no load on your system.

5.If Dyna Router quits or the computer shuts down during operation, will it affect the currently working devices?

No, it won’t. Once NDI encoder and decoder devices have established a connection, they communicate directly with each other. Dyna Router’s role is only to facilitate the initial connection setup. After that, even if Dyna Router exits or the computer shuts down, the existing NDI streams will continue uninterrupted.

6.What is the underlying principle of the Dyna Router matrix?

Dyna Router is developed based on the Router tool from the official NDI Tools suite by NewTek. It leverages NDI’s native routing capabilities to manage and redirect NDI streams within a network.

7.What is the basic logic behind the Dyna Router matrix?

The Pro version of Dyna Router provides 64 output channels, while the Basic version offers 32 output channels. When you launch the software, it automatically creates that fixed number of output channels in your NDI environment—this number never changes, regardless of your settings.
Presets (or "scenarios") are simply a way to organize and categorize these existing 32 or 64 channels for easier management—they do not create additional channels or remove any.
For example, if Output Channel 1 appears in multiple presets, it’s still the same single channel—it just shows up in different categories (other than the default “All” view) for convenience. There is always only one instance of each output channel.

8.Do the Trial and Basic versions of Dyna Router also create 64 output channels?

No. Only the Pro version supports up to 64 output channels.
The Trial version creates 4 output channels by default.
The Basic version creates 32 output channels by default.
These output channels are automatically registered in your local network environment based on the version you're using. Only the Pro version enables the full 64-channel capacity.

8.Can I reduce the number of output channels in Dyna Router?

No. Dyna Router uses a fixed number of output channels based on your license version—this number cannot be reduced or customized.

9.What is the purpose of Dyna Router’s primary/backup (failover) playback feature, and how do I enable it?

The primary/backup playback feature ensures automatic failover between NDI sources. Here’s how it works:
In the settings, you can arrange multiple NDI sources in a specific order for an output channel.
The output will initially use the first NDI source in the list.
If that source becomes unavailable (e.g., disconnects), the output automatically switches to the second source, then the third, and so on—providing seamless redundancy.
To enable this feature, go to the designated setting location in the software (as shown in the interface).

10.What is the purpose of Dyna Router’s auto-rotation (carousel) playback feature, and how do I enable it?

The auto-rotation (carousel) playback feature allows you to automatically switch an output channel between predefined NDI sources at scheduled intervals. You can also set specific times to turn an output channel on or off.
This is useful for scenarios like digital signage, monitoring rotations, or automated demo loops.
To enable this feature, navigate to the designated settings location in the software (as indicated in the interface).

11.In Dyna Router, what happens when I open a saved preset if one of the original NDI sources is no longer available?

The output channels on the right side will remain unchanged, preserving their previous routing configuration. However, any missing NDI sources will not appear on the left input side, since they are no longer present in the network. The preset retains its structure, but unavailable inputs simply won’t be displayed or active.

12.What is the maximum number of input ports in Dyna Router?

There is no hard limit—Dyna Router will list all available NDI sources detected on your network in the left-side input panel. The number of inputs depends entirely on how many NDI streams are present in your environment.
