We developed a special quick start function for QooCam 3 Ultra, offering two startup modes: quick start and slow start. Slow start takes about 20 seconds, while quick start only takes 1 second.
QooCam 3 Ultra achieves this through a two-stage power-off mechanism. In the first stage, the camera shuts down all other components but retains DRAM, allowing for quick startup. If the camera is off for more than 8 hours or the battery is replaced, the DRAM is cleared, entering the second stage power-off. In this case, restarting QooCam 3 Ultra requires a slow start, but subsequent starts can use quick start.

Due to the optical characteristics of panoramic cameras, stitching issues may occur when shooting underwater without a case. Therefore, we do not recommend underwater shooting without a case. The camera's waterproof design is meant to withstand impacts from surfing and waves, equivalent to the pressure at a depth of approximately 10 meters.

QooCam 3 Ultra supports IP68 dustproof and waterproof rating.

There is a built-in fan, and by navigating to Camera Settings - Fan, you can choose from the following three modes:

Silent Recording: The fan is completely turned off during recording, ensuring no fan noise. Once the recording stops, it reverts to "Cooling Priority."
Silent Priority: During recording, the fan operates at a lower speed when the temperature rises, producing minimal noise. After recording stops, it reverts to "Cooling Priority."
Cooling Priority: In all situations, cooling efficiency is prioritized, with the fan running at a higher speed, resulting in louder noise.

1. Check Your Computer Configuration Against QooCam Studio User Manual Recommendations Please ensure that your computer's configuration meets the recommended specifications as outlined in the QooCam Studio Tutorial

2. Make sure your graphics card driver is updated to the latest version. You can update your NVIDIA graphics card driver at the following address: NVIDIA Driver Downloads

3. For NVIDIA graphics card encoding and decoding capabilities, visit: NVIDIA Video Encode and Decode GPU Support Matrix

Detailed Explanation of Encoding and Decoding Capability Inquiry:

（1）In the QooCam Studio export, when the resolution is greater than 4K, the format needs to be selected "MP4(H265)" to support GPU acceleration.

（2）When the encoding capability of the graphics card is "YES", select this format in QooCam Studio to export the GPU acceleration.

For example: If your computer's GPU is a GeForce GTX 980 Ti, check the encoding capability of this graphics card.

The enclosed sections correspond to the following meanings for QooCam Studio: 

When exporting with H264 encoding format, when exporting with H265 encoding format (resolution ≤ 4K), when exporting with H265 encoding format (resolution ≥ 4K), and when exporting with HEVC encoding format (color depth 10bit, QooCam 3 Ultra and QooCam 8K can capture 10bit video), GPU acceleration is supported.

In this case, if the export resolution exceeds 4K, GPU acceleration cannot be used.

Support common Bluetooth remote controls on the market.

We have optimized QooCam Studio to support stitching with lens protectors. The lens protector is made of PMMA acrylic, a material with very high light transmittance, so the impact on the image is minimal.

Yes.

Yes.

Standard 1/4 inch thread.

The QooCam 3 Ultra supports the direct use of commonly available external microphones. Once an external microphone is connected, the QooCam 3 Ultra will automatically default to using the audio input from that microphone. 

The supported microphone types are as follows:

Bluetooth microphones, such as DJI mic 2;
USB microphones, such as the Rode Wireless Go series.

Final Cut Pro supports editing and exporting HLG videos, so you can confidently use Final Cut Pro for HDR video editing. It is important to use an HDR monitor to ensure proper color grading. You may need to pay attention to color space settings during editing to avoid using incorrect color space settings that could result in abnormal colors in the final output.

The 8K 360° VR HDR videos captured by QooCam 3 Ultra can be perfectly displayed on Apple Vision Pro. You can install the Kandao XR app on your Apple Vision Pro and transfer the HDR videos from QooCam 3 Ultra to Apple Vision Pro. Then you can watch the immersive HDR videos in the local video section of Kandao XR.

Yes, it is supported. Please stitch and process the footage from the QooCam 3 Ultra using QooCam Studio or the QooCam App and export it in a format required by Pico. Place the stitched materials on Pico for use.

This tutorial is using DaVinci Resolve. 

1. In 「Project Settings」, set the 「Color Management」 to 「DaVinci YRGB」, the 「Timeline Color Space」 to 「Rec.2100 HLG」, and the 「Output Color Space」 to 「Same as Timeline」.

2. The process typically requires about 4 nodes.

Node 1:
Adjust the brightness, using tools like「HDR – Color Wheels」. The reason that brightness adjustment is done in the first node is because different camera log gamma curves have different exposure biases, and after applying the LUT, the contrast usually changes significantly, making brightness adjustment fairly hard in later stage.

The standard HLG gamma of the 「QooCam 3 Ultra」 makes the brightness adjustment in Node 1 very precise.

Node 2:

Use the 「Color Space Transform」 effect from the 「Effects Library」 to convert HLG Rec.2100 to the target log space. In the example shown, it’s converting to 「Sony S-Log3 S-Gamut3」. 

For 「Tone Mapping Method」, I personally prefer 「Saturation Mapping」. 

Be sure to turn off both 「Apply Forward OOTF」 and 「Apply Inverse OOTF」.

Node 3:

Apply the LUT. Here, I’m using the official 「Sony LUT」 for converting S-Log3 to personalized color.

Node 4:

This step is to export a LUT that works for both HDR and SDR in QooCam Studio. The HDR to SDR conversion in Studio is from 「Rec.2100 HLG」 to 「Rec.709 Gamma 2.2」. 

Use the 「Color Space Transform」 effect from the 「Effects Library」 and set the 「Input Color Space」 to 「Rec.709」, 「Input Gamma」 to 「Gamma 2.2」, 「Output Color Space」 to 「Rec.2100」, and 「Output Gamma」 to 「Rec.2100 HLG」. 

For 「Tone Mapping Method」, I prefer 「Saturation Mapping」. 

Again, ensure that 「Apply Forward OOTF」 and 「Apply Inverse OOTF」 are both turned off.

For the final step, export the LUT (65-point Cube) and import it into 「QooCam Studio」. This LUT will correctly apply the desired color style in QooCam Studio, whether exporting in HDR or SDR.

Similarly, if your final output in DaVinci is an SDR video, set the 「Color Science」 in 「Project Settings」 to 「DaVinci YRGB」, the 「Timeline Color Space」 to 「Rec.709 (Scene)」, and the 「Output Color Space」 to 「Same as Timeline」, then remove Node 4.

Optical Flow Stitching: Suitable for static scenes; produces a more natural-looking image.

Dynamic Stitching: Best for moving shots; helps reduce distortion and compression in mid-to-near stitch areas.

Close-up Optimization: Ideal for tight spaces or when objects are close to the camera (e.g., inside a car); improves detail rendering in the foreground.
