encode review : 10h43 for 93 sec clip on old vista

[smartel]

i used XMedia Recode with this script :

LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\mt_masktools-25.dll")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\RemoveGrainSSE2.dll")
LoadPlugin("C:\Users\...\...\VIDEO\MeGUI_2507_x86\ tools\dgindex\DGDecode.dll")
DGDecode_mpeg2source("C:\Users\...\...\...\29\Symp horien ByeBye 2014_31_12_2014.d2v", info=3)
LoadPlugin("C:\Users\...\Desktop\VIDEO\MeGUI_2507_ x86\tools\avisynth_plugin\ColorMatrix.dll")
ColorMatrix(hints=true, threads=0)
Import("C:\Program Files\AviSynth 2.5\plugins\srestore.avs")
QTGMC()
Srestore(frate=29.97)
crop(100, 62, -100, -58)

result on YT http://youtu.be/HIZefGO0PKE

What took so long ? and what could be better ?

my vista was really busy so ... may be infected or loaded

pentium dual 1.8Ghz X2

Suggestions:

1) test the Avisynth script in AVSmeter

2) open the Task manager (ctrl + shift + esc) and see which processes might be interfering with Xmedia Recode

[jman98]

The fact that you are running Vista is not very useful for us to know. Knowing what your CPU is would be useful. I don't use QTGMC but I can tell you that it takes a lot of CPU resources to use it and for sure it's why your encodes are so slow. If you even have a CPU that supports multi-threading, you need to use a special version of QTGMC that supports multi-threading. That would speed up your encodes, but they may still take hours because QTGMC is always slow.

[jagabo]

Try QTGMC(preset="fast"). Use Task Manager to see what process is hogging up CPU time.

<edit>

Downloaded your MPG file. The script you used was inappropriate. The clip is straight 3:2 pulldown (no need for QTGMC -- unless you want it's other filtering) and had no field blending (no need for SRestore). Use this instead:

DGDecode_mpeg2source("Symphorien ByeBye 2014_31_12_2014.d2v", info=3)
TFM()
TDecimate()
crop(100, 62, -100, -58)

That took my computer (Intel 2500K) about 15 seconds to encode with x264 at the medium preset (which appears to be what you used). Your original script took about 8 minutes and resulted in jerky video (though the jerks are hard to see since there's not a lot of motion).

You should also correct for the aspect ratio or encode with SAR flags.

[smartel]

i always use task manager , everytime i boot up

well when i downloaded QTGMC i'm pretty shure i installed avisynth MT version with the instruction
but when done it didn't seam to show up , the 2 versions can co-exist ?

i could have save some time cropping before sRestore , i suppose

i really like the results that QTGMC and Srestore can do together

and i had Opencl (not OpenGl) error this week (and still have) , after installing and uninstalling some soft

that why i used XMediaR-portable 'cause it didn't complain ,

[jagabo]

Be careful cropping interlaced video. You need to crop vertically by mod4 to keep the chroma from blurring.

[smartel]

my source is from my tv card (ati 650)

does that mean that all my TV capture are straight 3:2 pulldown ??

or it may depend on the material that is aired , how can i tell ?

[smartel]

i won't crop interlaces clips i would deinterlace first

[jagabo]

my source is from my tv card (ati 650)

does that mean that all my TV capture are straight 3:2 pulldown ??

A large portion of it will be. Most movies and TV shows. Live sports will be pure interlaced.

or it may depend on the material that is aired , how can i tell ?

Apply a bob() filter (or QTGMC() or Yadif(mode=1) or SeparateFields()). If you see a pattern of two repeated frames and three repeated frames you have film with 3:2 pulldown. If every frame is unique you have interlaced video.

[jagabo]

If you're using a multithreaded build of AviSynth you need to use SetMtMode() to optimize for speed.

SetMtMode(mode=5, threads=4) # threads = try 1x to 2x the number of cores your CPU has
Mpeg2Source()
SetMtMode(mode=2)
OtherFilters()

Sometimes you need to add Distributor() at the end.

[newpball]

It would help if you could tell:

- What CPU is in the computer
- How much memory is installed
- A screenshot of the task manager (in administrator mode) while encoding.

You wrote: "pentium dual 1.8Ghz X2" , don't know what that means but if that translates into "duo core 2 1.8Ghz" then your computer is 8-9x slower than present day computers.

[jagabo]

On my computer this script:

SetMtMode(5,6) 
Mpeg2Source("D:\Downloads\Symphorien ByeBye 2014_31_12_2014.d2v", Info=3) 
SetMtMode(2)
QTGMC()
Srestore(frate=29.97)
crop(100, 62, -100, -58)

Took about 150 seconds to encode. This script:

SetMtMode(5,6) 
Mpeg2Source("D:\Downloads\Symphorien ByeBye 2014_31_12_2014.d2v", Info=3) 
SetMtMode(2)
crop(100, 60, -100, -60)
QTGMC()
Srestore(frate=29.97)

Took about 100 seconds. So cropping before QTGMC() and SRestore() is faster but you're more limited with the crop.

And this script:

SetMtMode(5,6) 
Mpeg2Source("D:\Downloads\Symphorien ByeBye 2014_31_12_2014.d2v", Info=3) 
SetMtMode(2)
crop(100, 60, -100, -60)
TFM()
TDecimate()
Deen()

Took about 14 seconds and had an image quality close to the QTGMC script. And of course didn't have the duplicate frames. I think it's a little over filtered and would tone Deen() down a bit.

What took so long ?

Basically your computer is too slow, your CPU benchmarks as 7-8-x as slow as present day computers.

That's why it took so long.

8 times longer than my computer's 2.5 minutes would be 20 minutes. Not 10 hours.

[smartel]

i used 2 scripts one feeding the other maybe that didn't help

Well CPU power is obviously not the only factor.

- Modern CPUs are better suited for video processing, your Pentium may lack some instructions.
- You are using an IDE interface.
- Also having less than 500 Mb left may trigger the OS to start paging some memory.
- Also it seems your OS drive and work drive are the same.

[jagabo]

- Also having less than 500 Mb left may trigger the OS to start paging some memory.

Of the things you listed that's about the only thing that could account for the 30x discrepancy. Try using SetMemoryMax(200) or so.

Hi,
It seems that the problems of hard drive (overheating, driver, aging elements). Ancient machine.
What will this test? > x264 HD Benchmark

[jagabo]

It seems that the problems of hard drive (overheating, driver, aging elements).

Not likely. The source is only 50 MB and the output file only 11 MB. His computer would take a month to boot if the hard drive was that slow.

[jagabo]

Another data point: An Athlon X2 255 (not too different from the OP's CPU) ran the original script in about 12 minutes with singled threaded AviSynth 2.6.

[smartel]

all my other encodes are going fine , i was thinking it was with the script

i tried x264 HD Benchmark but was really too slow
8 passes to do and after 30 minutes a was still at the 2nd pass
