MVtools questions

[smartel]

Will MVtools work on my Athlon 1800+ (no sse2)
can't seam to find the requirements for this plugin

i just want to convert an handheld camera shot
from 30 to 60 fps to feed to deshaker (lots of panning and fast motion)
i don't want to just double up the frames , just interpolate the missing frame

lots of avisynth plugins require sse2
and i want to find a workaround

thanks for your time , have a great day

my source is in .asf format

[poisondeathray]

I don't think it's a requirement, just makes it process faster

what error message are you getting?

what camera shoots directly to .asf .wmv ??

[smartel]

it's not my camera but a friend's ; i think it's a cannon but i'm not really shure

what would be the ideal script for this task ?

i just wanted to know before doing anything

[poisondeathray]

What does mediainfo say about the source file? (view=>text) copy & paste the results back here

There is no "ideal" script , you tradeoff speed vs. analysis quality options. There are dozens of different variations on motion interpolation scripts

What is your end goal ? PC playback? or something like DVD ?

It matters, because 30.0 fps is different than 29.97 fps (30000/1001) , and some devices and standard hardware require the proper 30000/1001

Also you have mono audio, does that matter to you? You can make it "fake stereo" by copying the channel

Motion interpolation has a lot of side effects - objects morph and you get edge dragging. It can look very bizarre. Some types of content are interpolated better than others

[smartel]

lots of end goal , both dvd and web (facebook and youtube) but mostly a good mpeg2

will try to mix it later with another camera shot (another format)
i will keep the audio format to mono ,

but for now i'm just preparing the sources if i can put it this way ..

ideally i'll go from 30 (.asf) to 60fps (.avi) and end up with 29.97(mpeg2) at the end

i just basically want a lot smoother playback from deshaker (or another tool !)

I taught MVtools was used also for noise reduction ?
if it introduced artifacts well i'll pass ...

ok, but for DVD you need to make it compliant - frame size and fps need to be "fixed" at some point in your workflow, and the audio is not compliant either - you would need to fix sampling rate

60.0 fps isn't compliant, and 60 to 29.97 implies that you are making it 59.94i (interlaced ?) because 59.94p isn't complaint with DVD or youtube etc... Youtube will only accept upto 30.0p

MVtools is used in a lot of filters for different purposes

The motion interpolation will always introduce artifacts of some sort. You're generating "inbetween" frames. On some types of content, it's barely noticable, on others it's very horrible

You can try it out the documentation gives you a simple variation (just copy & paste it). And there are several variations on interpolation scripts you can try as well

[smartel]

i'm thinking that a better frame rate doubling would give me better and smoother results from deshaker

a good feed for deshaker = better file for my mpeg2 encoder

avisynth script to virtualdub (deshaker) =30 to 60 fps
and then 60fps file to maybe HC via another script (60 to 29.97 (30 fps drop frame))

that's why i'm posting in the newbe forums

the audio will be muxed at the end

[poisondeathray]

It might be better , it might be worse, or anything in between. It really depends on the type of content

Here is a simple script for 2x (so 60.0 FPS if your source was 30.0 FPS) , for video only using the older mvflowfps from mvtools 1.x

source=FFVideoSource("video.asf")

backward_vec = source.MVAnalyse(overlap=4, isb = true, pel=2, search=3, idx=1)
forward_vec = source.MVAnalyse(overlap=4, isb = false, pel=2, search=3, idx=1)
source.MVFlowFps(backward_vec, forward_vec, num=2*FramerateNumerator(source), \
den=FramerateDenominator(source), idx=1)

If you wanted to use mflowfps from mvtools 2.x

source=FFVideoSource("video.asf")

super = source.MSuper(pel=2)
backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
source.MFlowFps(super, backward_vec, blend=false, forward_vec, num=60, den=1)

The results will be similar in terms of artifacts

[smartel]

i'll try that latter on this evening

got to go to work !

and thank you for your input

[smartel]

frame accurate seeking is not possible with this file
used mvtools2

[poisondeathray]

if it was cut incorrectly , you can get that error with ffms2

try another source filter dss2 , it comes with haali media splitter package. Put avss.dll in plugins folder

DSS2("video.asf")

[smartel]

l'll try first to make it seekable with asftools if that does not work i'll try it

[smartel]

i did both asftools repair and the dss2 thing my file is now being analysed 20 hours for a 25 min clip ouch !

i did the script with MEgui it crashed while doing it but i managed to save the script anyway

[smartel]

i'm now encoding
the preview in virtualdub looks good (xvid bitrate = 5000)

i'm still at 60 fps , should i have done it at 29,97??

the result of this will be dvd .. framerate convertion will be the next step

gives me time to read a little ..
read about MotionProtectedFPS from masktool (SalFPS3!??)

am i dearching too far ?

i'm aiming for smootest play

script used :

LoadPlugin("C:\Documents and Settings\Steve\Bureau\MeGUI_1989_x86\tools\avisynt h_plugin\avss.dll")
LoadPlugin("C:\Documents and Settings\Steve\Bureau\MeGUI_1989_x86\tools\ffms\ff ms2.dll")
DSS2("C:\Documents and Settings\Steve\Bureau\FNM\Nouveau dossier\Nouveau dossier\FNM_Jam06.lch.adv.ASF").AssumeFPS(30.000)
source=DSS2("FNM_Jam06.lch.adv.ASF")
super = source.MSuper(pel=2)
backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
source.MFlowFps(super, backward_vec, blend=false, forward_vec, num=60, den=1)
ConvertToRGB

i did it with no audio ...maybe i should have done it so that video and audio match in virtualdub ...

[poisondeathray]

You might have problems with sync, because many .asf/wmv files are variable frame rate and variable sample rate.

You can try this instead

source=DirectShowSource("video.asf", fps=30, convertfps=true, audio=true)
super = source.MSuper(pel=2)
backward_vec = MAnalyse(super, overlap=4, isb = true, search=3)
forward_vec = MAnalyse(super, overlap=4, isb = false, search=3)
source.MFlowFps(super, backward_vec, blend=false, forward_vec, num=60, den=1)
ConvertToRGB

This will include the audio and (hopefully) be in sync

Keep it at 60fps until you've finished exporting from deshaker and vdub , then do the framerate conversion and re-interlacing, and resample the audio

[smartel]

another day (or 2) of encoding for me ... i need one more pc

and thx again for the input

[smartel]

doesn't MVtool have it's own stabilisation capability ?

deshaker's results are so so

Depan, DepanStabilize , and related wrapper functions like Stab are avisynth stabilization functions

Deshaker results can often be optimized if you use better settings

[smartel]

i got to turn off the zoom fonction .. i think
