Avatour 360° Video File Size Calculator

This article gives advice and helps to decide on settings for recorded 360° video and the related file sizes.

How 360° video file size actually works
📐Resolution sets the potential
Resolution determines how many pixels exist in each frame — for example, 4K is 3840 × 1920 pixels. More pixels means sharper detail, especially when viewers zoom in on a specific area.
🎞Frame rate multiplies it
Frame rate is how many of those full-resolution images are captured every second. 30fps means 30 complete frames per second. Higher frame rates produce smoother motion but proportionally more data.
🗜Compression makes it manageable
Raw 4K video at 30fps would require over 5,000 Mbps — completely impractical. Codecs like H.264 and H.265 compress video by storing only what changed between frames, reducing this by 99% or more.
🎚Bitrate caps the quality
Bitrate is how much compressed data you allow per second. The encoder fits the best possible quality within that budget. Too low a bitrate for a given resolution produces blocky artefacts and loss of detail.
🚶Movement is the biggest variable
When the camera moves, almost every pixel changes between frames — compression becomes far less effective and file size grows significantly. A static camera compresses very efficiently because most of the scene stays identical frame to frame.
💡Avatour best practice
Put the camera down whenever you are not actively walking. Move slowly and deliberately between positions. This is the single most effective thing you can do to keep file sizes small and upload times short.

Resolution Quick Capture now offers 4K or 6K (5680 × 2440).

4K — frame rate and bitrate are yours to adjust using the sliders below.
6K — records at a fixed preset, either 30fps or 10fps. Both use CBR 30 Mbps — frame rate and bitrate aren't adjustable for 6K.
Use 6K at 30fps for sharper walkthroughs, or 10fps only for scenes where extra stillframe detail matters more than smooth motion.
?
Frame rate (fps) How many still images are captured per second. Higher frame rates look smoother when the camera or viewer moves, but increase file size proportionally.

Quick Capture allows 15–30 fps at 4K. The default of 30fps gives the smoothest result. 15fps roughly halves the file size but motion looks less fluid.
Use 30fps for walkthroughs with movement. Drop to 15–20fps for mostly static scenes where file size matters more than smoothness.
30 fps

Target bitrate Bitrate is the amount of data recorded per second. Higher bitrate means better image quality and larger files. This is the key lever in Quick Capture at 4K.

40 Mbps — maximum quality, ceiling for archival-grade recordings.
20 Mbps — high quality, a solid everyday default.
10–15 Mbps — good quality, significantly smaller files.
5 Mbps — minimum; noticeably lower quality, smallest files.
If you're uploading on a slow connection and need a quick turnaround, drop to 10 Mbps. For archival-quality recordings, use up to 40 Mbps.
20 Mbps

Recording duration Duration directly drives file size — longer recordings create proportionally larger files.

A failed upload midway means restarting from scratch. Long recordings also become harder to navigate during review.

PanoX V2 battery: approximately 90 minutes per charge.
Split long site visits into 20–40 min segments. Easier to name, upload, and review — and within one battery charge.
?
Storage capacity The PanoX V2 records to a microSD card (up to 1TB). Always use a microSD — the 6GB internal storage is for temporary use only.

The calculator shows how many recordings at your current settings will fit on the card.
The Avatour kit ships with a 64GB SanDisk Extreme PRO. At Quick Capture defaults (4K / 20 Mbps / 30fps) this holds around 6 hours of footage. Upgrade to 256GB+ for frequent use.

Best practices for Avatour recording
Use Quick Capture as your default
Quick Capture integrates recording directly with Avatour upload. It's the simplest and fastest path from recording to a shared asset.
Keep recordings under 40 minutes
Shorter files are easier to label, share, and review. They also reduce the risk of losing work to a failed upload. Aim for 20–40 min per recording.
Plan around battery life
The PanoX V2 battery lasts ~90 minutes per charge. Carry a power bank for longer site visits and always start with a full charge.
Drop bitrate to speed up upload
If you're uploading on a slow connection, reducing from 20 to 10 Mbps roughly halves the file size with only a minor quality difference.
Try 6K in Quick Capture for extra detail
Quick Capture now offers a 6K preset alongside 4K — no separate stitch step required. Choose 30fps for walkthroughs or 10fps when stillframe detail matters more than motion.
Use native app for the highest resolution
When maximum detail matters — reading equipment labels, serial numbers, gauges — switch to the native camera app and record at 5.7K, 6K, or 8K. You'll need to stitch before uploading.
Upload on a reliable connection
Use office or site Wi-Fi rather than mobile data. A dropped upload must restart from scratch. Check your upload speed before transferring large files.
