Pixelation at start of video

[vtwin500]

If I use my NVIDIA GPU to encode, the start of the video is pixelated at the bottom portion of the scene for a few seconds. Why would this happen? Using Handbrake with GPU does not do this.

I uploaded my files to the FTP server.

Also, how can I know if the encode is using the GPU or CPU by looking at the log files? What specifically do I look for?

This topic explains how to check if hardware encoding is being used:

GPU/Hardware Encoding/Acceleration FAQs

This topic is a compilation of the FAQs related to GPU and Hardware encoding 1. What platforms and devices are supported for GPU encoding MCEBuddy supports Intel (QuickSync), NVidia (NVENC/CUDA) and AMD (VCN/VCE/AMF) which are used for decoding and encoding H.264, H.265/HEVC and AV1. See FAQ 2 for driver requirements To use Intel QuickSync H.264 hardware encoders, Intel Sandy Bridge (1st Generation Core) or newer chipsets H.265 hardware encoders, Intel Broadwell (4th Generation Core) …

Thanks for uploading the files. I checked your cut MCE GPU.mp4 video file and I don’t see any pixilation. Playing back using VLC 64bit on Windows 10 and it’s clear. I think it’s an issue with your playback codecs. Attaching the screenshot, left is what I’m seeing, right is what you’ve reported:

Hmmm. I also am on Win10 x64 using VLC. Only GPU-encoded via MCE does this.

Thanks for the info.
