AVS Video ReMaker does offer Intel Quick sync & Nvidia CUDA GPU assist. 1080p, (re) encoding can require a considerable amount of time, especially using lower powered CPUs. At lower resolution &/or lower quality, re-encoding means noticeable quality loss, while at larger frame sizes, e.g. by adding transitions, means at the least those frames must be encoded, though just encoding those frames rather than the complete video can be iffy. Splitting video between keyframes, or altering the video, e.g. Keyframes are full frames that contain a complete image, while those frames in between only store the data that’s changed.

Like similar apps it splits video files at keyframes to allow it to copy the video content without re-encoding. adding fades, and gave just one choice for the format, LPCM, which is basically. It worked fine with 1080 p H.264 Blu-ray video in a quick test, but it’s maybe a bit weak when it comes to audio, which didn’t show up on a separate audio track for editing, e.g. AVS Video ReMaker does what it’s supposed to, letting you cut & join video files without re-encoding.
