Tyler restoring corrupted 4K snowboarding footage after cold-weather GoPro failure

I'm Tyler Blackwood, a snowboarder and content creator based in Canada. I'd spent months preparing for the Whistler Blackcomb Open, the biggest event of the year, and my shot at a major sponsorship hinged on one perfect run. I wore my GoPro Hero 12 Black on my chest and had a DJI Mavic 3 Pro tracking me overhead. When I landed the double cork 1260, I knew it was clean—it was the best jump of my life. But back at base camp, neither file would play properly. The GoPro footage froze every few seconds, glitched with green artifacts, and the audio was out of sync. The drone feed wouldn't open at all. My heart dropped, I realized these were the only recordings. Every second mattered. I quickly ran both files through Wondershare Repairit, and within minutes, the main 4K clip was restored in full quality, frame-perfect and smooth.

Video File Damage Situation

Challenge

It was -20°C at Whistler Blackcomb that morning, and halfway through my final descent, my GoPro Hero 12 Black suddenly powered off with no warning or no error message. Later, I learned the extreme cold had drained the battery mid-recording, corrupting the 3.7GB MP4 file stored on the SD card. Meanwhile, the drone operator lost control during my jump and crashed into a tree, damaging the microSD containing the 5.1K 30fps overhead angle. Back at the lodge, I tried opening both files on my MacBook Pro using QuickTime and Premiere Pro, but received “Invalid format” and “File is damaged” errors. The GoPro clip stuttered violently, with green screen glitches and audio lagging by over a second.

Solution

I discovered Repairit after searching “GoPro 4K file repair after cold crash” on Google. Within minutes, I downloaded the app and imported both corrupted files. Repairit recognized the H.265-encoded MP4s immediately and offered Quick Repair first. After a brief scan, it prompted me to try Advanced Repair for better results, especially since the drone footage was completely unplayable. I followed the guided steps, selected a healthy sample video from last week's training session, and let the software work. The preview loaded smoothly with no glitches. I could see every rotation of my jump even in slow motion. The repaired file maintained its original 3840×2160 resolution, 60fps frame rate, and electronic image stabilization metadata. Most importantly, the audio was perfectly synced. Knowing I had a backup angle from the drone gave me confidence, and Repairit recovered that too, 4.2GB of pristine 5.1K footage now usable for editing.
