Data Compression Techniques
Data Compression Techniques
Hello, I understand this might seem like a software problem, but I’m not convinced. I’m encountering an error while trying to record 4K at 60p. My goal is to capture the maximum resolution and quality possible. I’m curious about the cause of this issue—whether it’s related to the CPU, GPU, memory, or something else. In the recording settings: Format is MKV, Encoder is Nvidia NVENC, HEVC, with CQP and CQ Level set to 16. The preset is P7, which is the slowest but offers the best quality. Here’s what I see: MultiPass Mode uses two passes at full resolution. Software is OBS, the motherboard is MSI Pro b760-p with WiFi, DDR4 CPU, Intel Core I5-13400F, memory includes Vcolor 8x2 and 16GB, plus a Skywalker plus RGB with DDR-3600 SLVR. Storage is a 1TB A2000 NVMe SSD, and the GPU is Palit Vgcard RTX 3060 with 12GB DDR5. The case is Xigmatek Phantom, cooling system includes a Cooler Air Killer, and the power supply is a 650W Montech PSU. Thank you for your time.
Starting with a nice PC, it's mainly designed for gaming. The GPU and CPU won't handle multiple tasks well at once. A 64-core Threadripper and a 4090 might change things, but the 3060 with 12GB struggles with 4K games at max and can't do much else. If you need to record uncompressed, consider upgrading first. Most people won't notice the difference between uncompressed and slightly compressed 4K, thanks to other compression methods. If you plan to upload online, that's likely the case.
Did you eliminate the recognized Intel 13th gen problems? Check the most recent BIOS for your motherboard and see if it resolves the issue. Turn off overclocking as well to evaluate further.
I understand, but my setup is different—I'm using a PS5 and not the same PC.
Have you considered adjusting the capture options? They look overly broad for 4k resolution.
You're operating in CQP mode, which acts like a fixed quality setting. Imagine it as the JPEG quality percentage—0 means no loss, similar to PNG, while 100% is completely lossless. Around 50% corresponds to a 1% JPEG quality drop. The video codec examines each frame, determines what can be discarded, and begins reducing quality while calculating the appropriate quantizer level. Once it hits your chosen level (16 in this case), it stops further quality loss and proceeds to the next frame. In this setting, the preset doesn<|pad|>, not quality value, but indicates how much resources and calculation effort should be applied to reach that level using reduced storage. A higher preset can lead to smaller file sizes for the same quality, potentially saving up to 10 GB for a one-hour 4K video encoded at CQP 16, though visually it may appear identical to a preset of 16 and p4.
