Improve Quality of Downloaded FLV files..

[Deter]

Hi,

Just wondering if u can fix up or improve the quality of flv files downloaded from the internet. Found some really cool and rare videos however the picture quality is very blocky. The sound is also not the best.

These are rare videos that u really can't get or find anywhere.

There was some script i used(1-2 years ago) for improving low quality flv files, but ill have to find it (not in mine PC right now).
I used it for some blocky videos with fast moving objects.. i houp ill find the script for you.

Hi again, i have found the script, its from december 2008, so... i guess i have good memory
Its for interlaced flv video converted to avi(using virtualdub).. so if you have progresive one you should change some setings.

loadplugin("c:\x\dgdecode.dll")
loadplugin("c:\x\mvtools.dll")
loadplugin("c:\x\ttempsmooth.dll")
loadplugin("c:\x\nnedi.dll")

#load A&V
v=avisource("get_video.avi")
a=wavsource("get video.wav")
audiodub(v,a)

#correct video to true fps
assumefps(30,true)
resampleaudio(48000).getchannel(1,1)

#deblock/dering
s=DeBlock(quant=35).Blindpp(cpu2="ooooxx")

# very strong temporal denoising (stabilisation)
bv2 = s.MVAnalyse(isb = true, truemotion=true, delta = 2, idx = 10, blksize=16)
bv1 = s.MVAnalyse(isb = true, truemotion=true, delta = 1, idx = 10, blksize=16)
fv1 = s.MVAnalyse(isb = false, truemotion=true, delta = 1, idx = 10, blksize=16)
fv2 = s.MVAnalyse(isb = false, truemotion=true, delta = 2, idx = 10, blksize=16)
fc2 = s.MVFlow(fv2, idx=10, thSCD1=500)
fc1 = s.MVFlow(fv1, idx=10, thSCD1=500)
bc1 = s.MVFlow(bv1, idx=10, thSCD1=500)
bc2 = s.MVFlow(bv2, idx=10, thSCD1=500)
interleave(fc2, fc1, s, bc1, bc2) 
ttempsmooth(maxr=2, lthresh=40, cthresh=50)
selectevery(5,2)

#decimate out duped frames
selectevery(6,1,2,3,4,5)

#upscale to double size 
source=nnedi(dh=true,field=0).turnleft().nnedi(dh=true,field=0).turnright().sharpen(0.5)

#interpolate to 50fps for fluent motion
backward_vec = source.MVAnalyse(isb = true, truemotion=true, pel=2, idx=1,blksize=8)
forward_vec = source.MVAnalyse(isb = false, truemotion=true, pel=2, idx=1,blksize=8)
cropped = source.crop(4,4,-4,-4) # by half of block size 8
backward_vec2 = cropped.MVAnalyse(isb = true, truemotion=true, pel=2, idx=2,blksize=8)
forward_vec2 = cropped.MVAnalyse(isb = false, truemotion=true, pel=2, idx=2,blksize=8)
source.MVFlowFps2(backward_vec,forward_vec,backward_vec2,forward_vec2,num=50,idx=1,idx2=2) 
bicubicresize(720,576) #resize to PAL
converttoyuy2()
assumebff() #for PAL-DV
separatefields().selectevery(4,0,3).weave() #reinterlace

I hope it will do what you want.

How do you use this data? What will it do?

Since I started this post, came up with this crazy theory.....It has kind of worked....It is 2 crazy to write

It will make youre low quality FLV in to high quality HD blu-ray.

I'm joking ok?
So, you open this script vith Avsp, put the correct path to youre plugins, video and sound.. do little tweaking/changing to the script according to youre video source, and encode it.
This is an old script, so maybe some changes are needed for the updated plugins.
I'm going to sleep now, i cant explain or help you more right now.
