hi,

motion search precision in tmpgenc; is there any noticable difference setting from high quality to very high quality when encoding

my other question is; i have a 28" 100hz widescreen tv and would to fill the screen with my kvcds and not have the black borders, is this possible?

A) Difference will be much more time you need, but IMHO no visible diff.

B) You can by doing a PAN-Scan on your encodes or a proportional Zoom afterwards using your TV set. First method you shouldn't do cuase you'll kill movie informations at the sides AND you'll need much more bitrate to encode with, and in case of KVCD where we need as less bitrate as its possible, you'll end up with a worse quality result.
So use your Zoom function of the TVset IF avaiable.

Uops ... how do they appear on your 16:9 Set? Still little black bars on top and bottom in case of an encoded 2.35:1 Movie?
Or did you just forgot that 16:9 mode-Zoom in case of 4:3 sources... everything is possible

A) Motion Search Precision set to "Very High Quality" will actually produce a clip that is larger encoded as "High Quality". And as incredible said: No visible differences.
In fact you should go with Motion Estimate Search, since it produces the less artifacts from all these plus it's VERY fast.

For MA script only. For statics ones, I'm sorry but there is nothing else but High quality.

hey guys

thanks to all who answered my first question

incredible, yes when playing widescreen dvds 2.35:1 i still get those black top and bottom borders but they are not as big as when i produce a kvcd at say a 544x576 res if i could produce the kvcd to a 2.35:1 ratio i would be very happy.

any help mate?

cheers.

I you do so the TV set will distort the aspect ratio as it can handle only two format ! 4:3 and 16:9 (ie 1.77)

Even when you play a DVD that is 2.35, the standalone feed the TV set with a black bordered 16:9 image.

Could you please explain what are "MA scripts" and "statics"? I guess there's a lot I don't know.

MA = Motion adaptive
This means that a script contains routines/filters which do act individual based on what happens in the frames.
In Case of the KVCD MA script there is a command included

Ydifferencetonext()

And here's the MA part of Kwags optimal Script:
Code:
ScriptClip(" nf = YDifferenceToNext()" +chr(13)+ "unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ).TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1)* ")
So the luma will be compared from the actual frame to the next ( YDifferenceToNext() )and this gives a value (nf).
This value will be used mathematical to individual set continously the applied filters (unfilter for blurring and TempSoften for cleaning) in the script on each frame.

And "static" means you "just" use a script where every filter does use the exact same values on every frame.

What difference would the script make to the Motion Search? I have a script for DVD->DVD where a Motion Adaptive Unfilter Blur kicks in at very high action scenes. But there are static filters before that. Would that be considered an MA script?

Also I thought that Motion Estimate Search produces less artifacts in STILL scenes (DCT blocks on flat surfaces). In still scenes there won't be a big difference between MA scripts or static ones no?

Why do the strange artefacts found with 'High' appeared only when we switched to MA scripts ? I do not have the answer as it is in the internal code of tmpgenc.
But remember, months ago the optimal setting was "High" and by experience I can say that Motion Estimate is not good with the script I use.

I guess so.

You right. But I find problems are in motion scenes
