Incorrect or damaged video files need special handling.
Hello everyone. Here’s the link to the video: https://photos.app.goo.gl/4VCzoAWPawE1my5g8. My friend is experiencing an unusual issue, and I’ll walk through what happened step by step.
1. We both are deeply involved in the video and photo world—we shoot, capture, and edit regularly.
2. Both own Sony A6300 and A6600 cameras with basic specs (4K at 30fps, 8-bit, H.264, up to 100Mbps).
3. I suggested my friend upgrade to the Sony FX30 (4K at 60fps, 10-bit, 4:2:2, supports H.265, up to 600Mbps) plus a Lexar SD 256GB V90.
4. About three months ago, I set up a stationary computer for him (R 7 7700, Gigabyte B650 Eagle, 64GB DDR5, 1TB SSD + 1TB HDD). I installed Windows 10, but he later switched to Windows 11.
5. Around two months ago, during filming, the footage showed visual issues in the new computer. Initially, I suspected the FX30 or the SD card was faulty. He kept shooting with different settings and didn’t notice until recently.
6. On January 30th, a friend showed me some clips saved on one of the Lexar M620 SSDs. He tried color grading and everything worked fine.
7. Yesterday (January 31st), he began serious video editing and noticed the same problem again on the same material—no errors before. I considered it possibly related to the SSD or software, but then looked at older files from September 2024 stored on a Seagate 4TB HDD. The same pixelated blocks appeared.
8. Now I believe the issue isn’t with the camera or storage devices themselves, but possibly with the operating system or malware. Apologies for any confusion in my English. If you need more details, just let me know.
Due to these concerns, I question whether the PC might be unstable. For instance, if RAM is unreliable, errors could appear unpredictably during data loading. I’d perform a complete RAM test, such as MemTest86. Could you tell me the precise amount of RAM installed and its current speed?
Your device supports 2x G.Skill F5-5600J3036D32G. The XMP profile is configured at 5600 MHz.
I confirmed it isn't really old. My earlier notes about the RAM were just to verify if that was the issue. If it's about stability or maybe faulty, we should run some CPU tests to see if the problem clears up. Since you mentioned the issue changes so much, I don't think storage is the main concern, though it's still worth checking as a secondary step.
Yesterday at 7 h, the memotest86 test results indicate everything is fine with the RAM, no errors detected. The second screen showed 12 different memory test types and all passed without issues. Conclusion so far: the RAM modules aren’t the issue. Next steps: perform storage tests for HDD and SSD, and check the CPU—updates will follow! My IT knowledge is solid, especially regarding hardware. I remember in the days of DDR3, RAM chips were made for either Intel or AMD processors. Now I see that DDR5 offers similar capabilities, which aligns with what memotest86 mentioned under "Intl" for RAM types. This seems unrelated to the problem, though someone might have a different version.
This provides some assurance the RAM isn’t clearly defective. Still, there’s a chance the memory controller could be inconsistent. I’ve seen memtest pass but Prime95 failed quickly, so I know execution matters. Consider running Prime95 for about ten minutes—its large FFT sizes create a different pattern that might challenge the controller more than other tests. For execution-specific checks, a brief FFT test is better since it works in cache and doesn’t heavily load memory. With AMD CPUs, Prime95 behaves differently from Intel, so I’m not recommending it for CPU stress. This exercise mainly targets the memory controller. One note: the screenshot shows 4800MT/s while the modules claim 5600. Early DDR5 kits were promoted to Intel, but AMD hasn’t joined recently. It’s possible the difference is just packaging. For DDR3 or earlier, there used to be side-by-side module support, so some units were labeled for only one profile.
Apologies for the delay, have a nice week. Regarding XMP, it wasn't enabled by default. I believed "DDR5 auto boost" activated it, but now I realize it doesn't—this was my first time using a DDR5 system. I plan to update after testing with Prime95. A quick question: does your friend use the MPC player with all codecs (H.264, H.265, etc.)? Could that be the cause? Thanks for your help!
Consider another participant if issues arise. VLC is widely used and can handle most tasks. Are their positions aligned?
