I made a mt 2.5.8 avisynth.dll and mt.dll

[Jeremy Duncan]

Arshad07,

I tried a few encodes. First I demuxed the audio from video using tsmuxer. I only used the video in the encoding. I had to switch where the filters went. After I used tsmuxer I used dgsplit to rip 100MB and used the extension on the tsmuxed video file on the dgsplit file.
Loadplugins
setmtmode(5)
DirectShowSource
MT("
LimitedSharpenFaster
",2)
spline64resize # this wasn't using mt and it worked fine
Setmtmode(2)
mvtools code

I could see the part of the video I cliped using dgsplit was not entirely in the encoded version. i was missing around 30 seconds of the minute I prepared for encoding tests. I could not get the whole 60 seconds regardless of how i tried various scripts.
I don't encode blu ray but I think maybe directshowsource can't handle the .mpv I was using with it.
So what I'm saying is you may encode and eith er see a ugly picture because the filters were not stacked right, or you may not see the whole movie only half of it.

mdegrain is in mvtools2, mvdegrain is in mvtools.

@Jeremy Duncan

Whats better in your opinion, MT or SETMODE?

Hi,

You can get infos at the source:

Whether MT or SetMTMode is better depends greatly on what the script is trying to do. Try using one, then the other, and finally use what works best. SetMTMode is probably safer, but a little slower in some cases. Like BigDid said, read the info and experiment.

I beg to differ. With it's increased threading stability, you can run v2 faster than you can v1 when using functions such as SetMTMode.

Hi Merlin,

http://forum.doom9.org/showthread.ph...53#post1286353
I did not had the opportunity to thank you for mirroring the MT 2.58 files, also to Jeremy for starting the thread and to SET for his alternate dll

It seems more and more people are using the MT 2.58 without always reading the doc first

@BigDid
You are more than welcome! Mirroring the files is the least I could do.

Is there any way to increase the speed of this script, cos its not using my cores that much; only like 40% [ with XviD ]

Increase the number of threads. I mean, change the '4' in the end of the script to something like 6 or 8. Here, with my dual-core CPU, '3' is the magic number.

Problem with a bigger number of threads than cores is when a scene gets more demanding 2 cores won't be able to process 3 threads and it will start slowing down and loosing frames.
You should find a demanding moving scene when testing CPU usage.
After a lot of testing best is SetMTMode(2).
Then focus on setting up the actual filters parameters.

[Arshad07]

Anyone could check the sample, the video is messed up using SetMtMode and MT

What would be a syntax example for an MT script using lsfmod?

Something like this would work?

SetMTmode(2,2)
directshowsource("file.avi")
lsfmod(smode=5)

Directshowsource(avi)
LimitedSharpenFaster(strength=50)

Of course, lsf requires removegrain

Why LimitedSharpenFaster instead of lsfmod?

I am a beginner in this sharpening matters, so I would like to try different ways and learning about them.

Hmmm... Weird, because here the problem with 2 threads using a dual-core CPU is that AviSynth (with a MVTools script) can't load the CPU entirely (i.e.: not 100%), slowing down videos with large resolution. With 3 threads I can get a full load and better performance. Maybe we need another opinion here, ahn?

Hi,

3 threads for
- the setmtmode() like (1,3)
- for the xvid encoder
- for boths?

I have 2 cores also, use defaut (0) or 2 cores and I am willing to try

You can use LSFmod in the same way. LSFmod is a little newer in comparison to LimitedSharpenFaster. It has a couple of bug fixes, and more features. Just replace the LimitedSharpenFaster line with your own LSFmod line and you should be fine.

I mean 'setMTMode'. I don't know anything about the Xvid encoder, hehehe.

If I'm using only the following in a script, do I get any benefit out of using any sort of multithreading in Avisynth itself? How would I do it? Since DGMPGDecNV runs on the GPU, I assume that it can't be multithreaded using MT or SetMTMode (unless anyone knows to the contrary). Suggestions? Thanks!
