| − | == Intro ==
| + | |
| − | '''SVP 3.1''' and later is based on SVPflow Avisynth plugins.
| + | |
| − | Additionally, Vapoursynth plugins was developed for the multi-OS '''SVP 4'''.
| + | |
| − | | + | |
| − | Motion vectors search plugin (svpflow1) is a deeply refactored and modified version of '''MVTools2''' Avisynth plugin and we're grateful to all of MVTools authors: '''Manao, Fizick, Tsp, TSchniede and SEt''' for developing such a great library.
| + | |
| − | | + | |
| − | '''SVP wouldn't be ever possible without it'''.
| + | |
| − | | + | |
| − | We're also providing [[Plugins: MVTools2|modified MVTools 2.5.11]] with GPU-accelerated '''MSmoothFps''' function.

| − | ==== SVSuper(source, params_string) ====
| + | |
| − | Get source clip and prepare special "super" clip with multilevel (hierarchical scaled) frames data. The super clip is used by both '''SVAnalyse''' and '''SVSmoothFps''' functions. For storing and transferring its parameters we use audio properties of super clip (specifically, num_audio_samples) as a trick. So, audio is killed in super clip.

| − | * 1 - sharp picture without any blending, moves pixels by motion vectors from next frame to current. Requires only backward motion vectors ("analyse.vectors: 2") so it's the fastest possible method.
| + | |
| − | * 2 - like 1st but moves pixels from the nearest (in terms of time) frame so it uses both backward and forward vectors. Recommended for 2D animations.
| + | |
| − | * 11 - time weighted blend of forward and backward partial motion compensations.
| + | |
| − | * 13 - same as 11th but with dynamic median added. Produces minimum artifacts but with noticeable halos around moving objects.
| + | |
| − | * 21 - 11th plus additional cover/uncover masking to minimize halos and improve frame edges.
| + | |
| − | * 23 - 21th plus extra vectors from adjacent frames for further decreasing of halos, can be less smooth than 21th.
