How Much 4K Video Can You Really Fit on a 64GB Drive
RedTiger Dashcam Information
If you've ever used a dash camera like the RedTiger F7NP to record 4K video, you might be surprised how quickly your storage disappears. One minute you're capturing beautiful footage of the open road - the next, you're out of space. So how much 4K video can you actually store on a 64GB memory card? Let's do the math.
The 4K File Size Breakdown
Each 5-minute 4K video clip recorded by the RedTiger F7NP is approximately 934.7 MB. This is fairly typical for compressed 4K video at a good bit rate. With that baseline, we can estimate how much you can store.
The Numbers Behind the Storage
Most memory cards labeled "64GB" actually provide about 64,000 MB of usable storage, since manufacturers calculate 1GB as 1,000MB (not the binary 1,024MB).
So the number of full 5-minute videos you can store is:
64,000 MB ÷ 934.7 MB = ~68.45
You can store 68 complete files. Anything beyond that won’t fit.
That's 340 Minutes of 4K Footage
Each clip is 5 minutes long, so:
68 clips × 5 minutes = 340 minutes
Converting that to hours:
340 minutes ÷ 60 = 5.67 hours
You’ll get approximately 5 hours and 40 minutes of continuous 4K recording on a single 64GB card.
What Could Affect That Number?
- System files and indexing structures on the card
- Minor fluctuations in compression ratios
- Other media files stored alongside your videos
In real-world use, expect a bit less - closer to 5.5 hours depending on your exact configuration and usage.
Final Thoughts
If you're heading out for a long drive and want to capture the whole experience with your RedTiger F7NP, having multiple memory cards on hand is a smart move. A 64GB card will cover around 5.5 hours, but if you're recording non-stop, that time goes by fast.
Know your limits - and plan ahead for uninterrupted recording.
