Unofficial VirtualDub Support Forums > Newbie Questions > Truemotion Plugin?

Posted by: Elaphe666 Dec 20 2013, 09:56 PM

Is there any plugin that adds intermediate frames in a 30 fps video to make it look like 60? I mean something like what some modern tvs do with the image (some call it truemotion) and that makes the movies look like a homemade video. If a TV is able to do this almost in real time, I suppose there must be a plugin to transform a video and have a sense of smoother motion. Thanx.

Why would anyone want to something so evil to a poor defenceless video ?
It's usually best to leave 'buggering up the video' to a separate device and leave the original alone so not everyone has to suffer through the effect

Seriously though, it's also called "Motion interpolation" and avisynth's probably the best bet for doing it
Can't recommend anything as it's not something I'd touch

+1

Smooth Video Project (SVP) comes with tools that just played meowmeow's 25 fps video as 60 = ( ^ _ ^ ) =

Feature to open avs script in VD yet still to fix (says YV12 not YV12 or something it don't likes)
Could be interesting to see what they exactly do with frames and which one is better.

I already have programs that simulate truemotion, such as Splash Pro or PotPlayer. However, I need to convert the original video files because I need to apply the home videocamera look. It's incredible VirtualDubMod lacks a plugin for this. Is that Avisynth another video editing program such as VirtualDubMod?

@Elaphe666

I would like to advise you to use VirtualDub 1.9.11.x (or later) and NOT VirtualDubMod that is already 'old' (end of 2007).
You can find it here: http://sourceforge.net/projects/virtualdub/files/virtualdub-win/
Installation goes by un-zipping the files to a folder like C:\Program files\VirtualDub (there is no setup or install).
Start the program via VirtualDub.exe (NOT Vdub.exe).

In VirtualDub you will find the "Interpolate" filter (via Video-menu > Filters... > Add), and this one should do what you are looking for.

At Frame rate target, select Scale frame rate by 2
At Interpolation mode, select Linear blending

This will create your intermediate frames and the motion will be 'smoother'.

Interpolate filter does a different thing
That one makes a blurred effect, by merging frames together like bad deinterlacing

Why incredible?
More like nobody actually wants to write one
People only write plugins for something they're interested in or want to do
tbh, I wouldn't waste 5 mins writing such a plugin

Avisynth is a script language for video that can load plugins and 'do things' to the video
You then can load/play the .avs script file like a video
There's quite a bit on google -> avisynth motion interpolation
Takes some setting up, but can be done

Thanks, now encoding "TruMotion" alikes in VD

The framedoubting err, framedoubling scripts from AviSynth site as examples:

'Fastest':

CODE

#loadplugin("c:\program files\avisynth 2.5\plugins\mvtools2.dll")
#To double fps with MFlowFps for fastest (almost) real-time playing:
AVISource("c:\test.avi") # or MPEG2Source, DirectShowSource, some previous filter, etc
# assume progressive PAL 25 fps or NTSC Film 23.976 source
super = MSuper(pel=1,hpad=0,vpad=0,chroma=false)
backward_vec = MAnalyse(super, blksize=32, isb = true, chroma=false, searchparam=1,search=0)
forward_vec = MAnalyse(super, blksize=32, isb = false, chroma=false, searchparam=1,search=0)
MFlowFps(super, backward_vec, forward_vec, num=2*FramerateNumerator(last), \
den=FramerateDenominator(last), mask=0)

Looks not much better than blurring frames. This I dropped quickly.

'Best' (for encoding):

CODE

#loadplugin("c:\program files\avisynth 2.5\plugins\mvtools2.dll")
#To double fps with MFlowFps for 'best' results (but slower processing):
AVISource("c:\test.avi") # or MPEG2Source, DirectShowSource, some previous filter, etc
# assume progressive PAL 25 fps or NTSC Film 23.976 source
super = MSuper(pel=2)
backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
# Use block overlap, halfpixel accuracy and Exhaustive search
forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
MFlowFps(super, backward_vec, forward_vec, num=2*FramerateNumerator(last), \
den=FramerateDenominator(last))

Lacks GPU support, multithreading, etc... Visible "wave" artifacts for some frames and probably there's more.

Is that MVTools 2?
There's also a supposedly better one at http://www.svp-team.com/wiki/Plugins:_MVTools2

Posted by: raffriff42 Dec 21 2013, 09:11 PM

Get MVtools2 per @dloneranger, and also get Interframe:
http://forum.doom9.org/showthread.php?t=160226

Calling is simple - here's an example:

CODE

AviSource("source.avi")
InterFrame(Preset="Medium", Tuning="Smooth", NewNum=60, NewDen=1)

Results are very good.

1.84% better (PSNR-256-Y-YUV) than avs example (using mvtools2 from SVP) in my test in 5160 frames.

Can't get interframe to use GPU with
InterFrame(Preset="Medium", Tuning="Smooth", NewNum=60, NewDen=1, cores=2, gpu=true)

SVP's best as it can play 1920x1080@60 in full screen realtime

(through ffdshow - any player automatically but VD)
