AVS Video ReMaker does what it’s supposed to, letting you cut & join video files without re-encoding. 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. adding fades, and gave just one choice for the format, LPCM, which is basically .wav. Like similar apps it splits video files at keyframes to allow it to copy the video content without re-encoding. Keyframes are full frames that contain a complete image, while those frames in between only store the data that’s changed. Splitting video between keyframes, or altering the video, 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. At lower resolution [frame sizes] &/or lower quality, re-encoding means noticeable quality loss, while at larger frame sizes, e.g. 1080p, (re) encoding can require a considerable amount of time, especially using lower powered CPUs. AVS Video ReMaker does offer Intel Quick sync & Nvidia CUDA GPU assist.
Installing AVS Video ReMaker means installing 3 Microsoft C/C++ runtime packages, with quite a few associated registry entries, several setup files stored in ProgramData & Windows\ Installer folders, and several mfc140.dll etc. files added to Windows\ System32. Just short of 100 mostly ActiveX files are added to the Common Files folder and mean quite a few added registry entries as well. If you open the included Help file it instructs you to either use the online help, or download and install the full help file, which include help on all of the developer's apps – not just Video ReMaker.
