FixFPS

Latest revision as of 02:23, 21 April 2020

[edit] Description

Fix the frames to a more consistent pattern with the help of Matroska Version 2 Timecodes. Mostly useful for fixing weird framerate from using a third party program to capture (ex. .kkapture with Mupen). Generally used with the plugin ExactDedup. It should be noted that FixFPS would try it's best not to lose any frames from the source. It does this by pushing frames to the next available spot, if possible, but it can cause side effects.

[edit] Requirements

• [x86] - AviSynth+ | AviSynth 2.6
• [x64] - AviSynth+
• Supported color formats: RGB24, RGB32, Y8, YV12, YV16, YV24

[edit] Syntax and Parameters

FixFPS (clip c, string "times", int "frames", int "div", int "mul")

clip   =

The clip to use as the source.

string  times = "times.txt"

The path to Matroska timecodes (v2).

int  frames = 30000

The output frame count.

int  div = 2

The divider of the original frame rate to align to.

int  mul = 1

The multiplier of the frame rate after the divide.

[edit] Examples

Let's say you capture Super Mario 64 with .kkapture and Mupen. You know the gameplay of Super Mario 64 is 30 FPS, but the intro Nintendo logo is 60 FPS. Normally the capture from .kkapture is 120 FPS. So the divider is 120 / 30 = 4 (to align to 30 FPS) and multiplier is 60 / 30 = 2 to output to 60 FPS. Here is a possible script:

LoadPlugin("ExactDedup.dll")
LoadPlugin("FixFPS.dll")
AVISource("Mario64.avi")
trim(0, 5999) # You might want to align to the divider, so in this case a multiple of 4
ExactDedup(firstpass=false, dupinfo="Mario64 dups.txt")
FixFPS(times="Mario64 times.txt", frames=1500, dic=4, mul=2)

                                  likely to get jerky movement when the multiplier 
                                  is greater than 1
