1. What is Spatial Video and why is it such a storage hog?
Ever since Apple launched the Vision Pro, iPhone 15 Pro, and iPhone 16 series, "Spatial Video" has become the hottest topic in the tech world. Unlike the standard 2D videos we're used to, Spatial Video uses both the main and ultra-wide cameras on your phone simultaneously to capture depth data between objects. When you watch it back on a VR headset, the people and scenery pop out right in front of you in 3D—it's incredibly nostalgic!
However, the price for such realistic 3D effects is that the file sizes are massive storage hogs. According to official specs, shooting Spatial Video at 1080p 30fps eats up about 130MB for just 1 minute of footage. If you're traveling and shoot 10 minutes a day, that's nearly 9GB in a week! With the industry pushing towards 4K and higher frame rates for Spatial Video, future file sizes will absolutely skyrocket. When you want to back up these precious 3D memories to iCloud or Google Drive, or send them to family and friends, a weak home broadband connection will leave you waiting forever. That's when many people finally realize that a smooth internet experience isn't just about download speeds—upload speed is the real MVP here!
- Massive depth data: Besides the left and right images, it has to store 3D coordinates, doubling the file size.
- High-resolution demands: To avoid pixelation inside a VR headset, the video bitrate is usually set very high.
- Cloud sync pressure: Auto-uploading to iCloud right after shooting demands extreme upload stability from your network.
2. Uploading Spatial Video: Why is upload speed the key?
When signing up for home broadband, many Hong Kong consumers only look at whether the plan is "1000M" or "2500M", often ignoring that this number usually just refers to the download speed. Our daily habits like watching Netflix, scrolling through IG, or gaming rely heavily on downloading. But when you need to back up tens of gigabytes of Spatial Video from your phone to the cloud, or post it on YouTube to share with friends, that action is called uploading.
Broadband in the Hong Kong market mainly falls into two categories: symmetrical and asymmetrical. Standard Fiber-to-the-Home (FTTH) plans from providers like HKT or HKBN are usually symmetrical, meaning 1000M download comes with 1000M upload—this is the perfect setup for handling Spatial Video. However, many people have recently switched to 5G home broadband for convenience. While downloads can hit 300M or even 500M, the inherent physical limits of mobile networks usually cap upload speeds at around 30M to 50M. If you're using a 30M upload speed to push a 10GB Spatial Video, you could easily be waiting over half an hour! And if the connection drops halfway, you have to start all over again—a total waste of time and effort.
⚠️ Note: If you notice your iPhone can't finish backing up videos even when plugged in every night, there's a high chance your broadband upload speed has hit a bottleneck, or you've been throttled by your ISP's FUP (Fair Usage Policy)!
3. Broadband upload speed showdown: Is yours fast enough?
To give you a clearer picture, we've compared several common home broadband plans in Hong Kong. Let's say you need to upload a 10GB Spatial Video file (roughly an hour of 1080p Spatial Video, or just over ten minutes of a future high-res version). How long will you have to wait with different upload speeds? Check out the table below to see for yourself:
| Broadband Type | Theoretical Upload Speed | Est. Time to Upload 10GB | Target User |
|---|---|---|---|
| 5G Home Broadband (SmarTone/CMHK, etc.) | ~50 Mbps | ~27 mins | Light users, village houses without fiber |
| 1000M Fiber-to-the-Home | 1000 Mbps | ~1.5 mins | Average households, regular video shooters |
| 2500M (2.5G) Fiber | 2500 Mbps | ~35 secs | Tech enthusiasts, frequent Spatial Video shooters |
| 10G Fiber Broadband | 10000 Mbps | ~9 secs | Pro production houses, YouTubers, extreme power users |
As you can see from the table above, traditional 1000M fiber broadband is more than enough for most users, knocking out a 10GB upload in under a minute and a half. It's a highly practical and cost-effective choice (monthly fees usually hover around $98 to $138). But if you're a hardcore Apple fan shooting loads of Spatial Videos daily, or if you have multiple devices backing up simultaneously at home, upgrading to 2500M fiber will absolutely smooth out your experience. You won't have to worry about hogging the bandwidth and causing your family's games to lag!
4. Pro tips: How to fix network bottlenecks at home or the office?
Some of you might ask: "I've already signed up for 1000M or even 2500M fiber, so why is my iPhone still uploading Spatial Video so slowly?" It's time for a network health check! The speed of the broadband entering your home is just the first hurdle. The Wi-Fi signal beamed from your router to your phone is where bottlenecks are most likely to happen. To fully unleash your broadband's upload potential, follow these steps to optimize your network:
- Leverage Wi-Fi 6E or Wi-Fi 7: The iPhone 15 Pro supports Wi-Fi 6E, and the iPhone 16 series already supports the latest Wi-Fi 7. If your router is still rocking Wi-Fi 5 (802.11ac) from a few years ago, your upload speeds will max out at 400-500 Mbps. Upgrading to a new router that supports the 6GHz band can help you dodge interference from neighbors, sending your upload speeds through the roof.
- Check your LAN cable specs: The LAN cable connecting your modem to your router is crucial. If it's an older CAT5e cable, it'll only handle up to 1000M. To truly tap into the power of 2500M broadband, you must swap it out for a CAT6 or higher ethernet cable.
- Placement and Mesh Wi-Fi: If you're trying to auto-backup videos in your bedroom but the router is in the living room behind two structural walls, signal degradation will tank your upload speeds. This is when you should consider installing a Mesh Wi-Fi system to blanket your entire home in high-speed internet.
💡 Pro Tip: If you have massive Spatial Video files that you urgently need to transfer to your computer for editing, the most stable method is always using a USB 3 (10Gbps) Type-C cable to transfer them directly to your Mac. You can then upload them from your computer via a LAN cable—this is the ultimate zero-latency hack!
5. Summary: A broadband upgrade is essential for seamless Spatial Video sharing
Technology is advancing at lightning speed, and Spatial Video brings us an unprecedented, immersive way to experience our memories. Just imagine putting on a headset a decade from now and watching 3D footage of your kids growing up or your pet running towards you—that kind of emotion is absolutely priceless. But to properly store and share these precious, massive files, a home broadband network with robust upload speeds is an indispensable piece of infrastructure.
If you find your current broadband plan is starting to struggle, with constant backup failures or uploads that put you to sleep, now is the perfect time to review your contract. Whether you're upgrading to 1000M fiber or going all out with 2500M or even 10G, major Hong Kong ISPs are currently offering plenty of highly cost-effective options. Fix that network bottleneck, and you'll never have to hold back on shooting Spatial Videos again. Go ahead and capture every 3D moment of your life to the fullest!
