25 fps progressive. Is there a way to have more smooth video?

[marcorocchini]

Hi ****,

with the gopro camera I have shoot a little attached video that seems a little jerky because of the 25 fps progressive.

I wonder: is there a way, in avisynth (or other programs) to have a more smooth video?

thanks

Motion interpolation techniques can work well with video that doesn't have complex or too fast motion.

You'll need mv_tools2 to use that function. It generates noticeable artifacts with your video though.

my target, for the moment, is a SD monitor standard interlaced

I try to understand if exist a particular avisynth script that can reduce the jerking in image, possibly without artifacts or minimum artifacts

576i25 TFF:

import("C:\Program Files (x86)\AviSynth 2.5\plugins\DoubleFPS2.avs") 

ffVideoSource("gopro.mp4") 
BilinearResize(720,576)
DoubleFPS2()
AssumeTFF().SeparateFields().SelectEvery(4,0,3).Weave()

There WILL be artifacts.

You can try adding motion blur with QTGMC to create 25 fps video that flickers a little less.

ffVideoSource("gopro.mp4") 
BilinearResize(720,576)
QTGMC( Preset="Fast", InputType=1, ShutterBlur=1, ShutterAngleSrc=30, ShutterAngleOut=360)

If you didn't mind the speed-up, you could:

AssumeFPS(pal_double)
