1.What’s the main functionalities of Vela?

Vela is a multi-functional device that supports 12G-SDI bidirectional encoding, decoding, recording, and live streaming‌. It is compatible with various streaming protocols including RTMP, RTSP, SRT, and NDI‌, and supports local SSD recording‌.

2.What resolutions and formats does Vela support?‌

Vela supports HD (720p, 1080p) and UHD (4K) video formats. The encoding types include FULL NDI, NDI|HX2, NDI|HX3, H.264, and H.265. It records in H.264 and H.265 and supports playback of H.264/H.265-encoded MP4 and MOV files.

3.How to Perform a Firmware Upgrade?

There are two methods to upgrade the firmware: ‌Dyna Hub Software‌ and ‌API‌.

Using Dyna Hub:‌ Select the target device, load the firmware file, and the device will automatically restart after the upgrade is complete.

4.What is the Result When Dyna Hub and Touchscreen Are Used Simultaneously?

When both ‌Dyna Hub‌ and the ‌touchscreen‌ are used for control, the system follows the ‌last received command‌ (no priority is assigned to either method).

‌

5.Why does Vela show a red network connection indicator after joining a LAN?

‌If the LAN is connected to the internet,‌the red indicator will turn green once Vela is assigned an IP address. This process may take a few moments.

‌If the LAN is not connected to the internet,‌ the indicator will remain red until Vela obtains an IP address (instead of displaying a MAC address), indicating successful device connection.

6.Does switching between encoding/decoding signal resources cause the output display to freeze?

This occurs because both encoding and decoding share the same resource channel. Video source switching triggers resource reallocation, pausing active encoding/decoding tasks. The system resumes automatically after a brief delay.

7.When Vela performs simultaneous encoding and decoding, if recording is enabled, has the recorded video been saved in its encoded or decoded state?

The recording function only saves the video stream that is currently being encoded.

8.If Vela is performing simultaneous encoding and decoding, is the HDMI output displaying encoded or decoded video/audio?‌‌
The HDMI display priority follows this order:‌Media playback‌ >‌Decoding>‌‌Encoding‌, if no decoding is active, the HDMI output will default to ‌encoded‌ video.

9.Does the TFT screen display appearslightly stretched?

The TFT screen has a resolution of 960×412. When displaying 16:9 content, black bars will appear on both sides due to the aspect ratio mismatch. To compensate, the on-screen image is slightly stretched, which is normal behavior. For the correct display, refer to the HDMI output.

10.Does Vela support simultaneous streaming to multiple live platforms?‌
Currently, Vela only supports ‌single-stream output‌ (one live stream at a time).

11.Can Vela connect to a USB drive for reading/writing?‌‌
No, Vela's USB ports are exclusively designed for connecting USB cameras. The only supported storage device is an SSD (Solid State Drive).

12.Can the hard drive be removed immediately after recording ends?‌‌
No, please wait a few minutesafter recording completes before removing the hard drive. Do not play back the recorded video during this time, as doing so may corrupt the video files.

13.When connecting the C1 hard drive to a desktop computer, the system may become sluggishor freeze.‌
The C1 hard drive requires sufficient power. If the desktop is already connected to USB devices (e.g., mouse, keyboard), avoid plugging the C1 drive into the ‌same USB port group‌ (e.g., use rear ports for the C1 drive if peripherals are connected to front ports).‌‌
