For systems with NVIDIA GPUs, the NVENC (video encoder) and NVDEC (video decoder) hardware can be used to handle high-resolution 4K streams with minimal CPU usage.
While primarily a player, VLC includes a "Convert / Save" feature that is useful for quick, simple transcoding tasks directly from its menu. 2. Hardware Acceleration (Speeding it Up) Linux Transcoding Software
If you have an Intel CPU with integrated graphics, you can use QSV to transcode videos much faster than the CPU alone. On Ubuntu, you can install the intel-gpu-tools to monitor this performance. For systems with NVIDIA GPUs, the NVENC (video
A popular open-source transcoder with a graphical interface. It is excellent for beginners who want to use presets (like "Fast 1080p") to convert MKV or MP4 files without learning complex commands. Hardware Acceleration (Speeding it Up) If you have
AMD GPUs use the Advanced Media Framework for hardware-accelerated encoding. 3.
