MeGUI development

[Sharktooth]

not yet and btw it's auto 3 pass that's b0rked even without turbo.

I see. Any idea what is causing the flaw?

[charleski]

I can take a look into automated 3-pass, though I only use 2-pass and after searching the forum I see that no-one's specified exactly what problem they're having. It seems to be a flaw in the command-line generation, though.

[Chainmax]

Sharktooth made a post somewhere explaining the problem. I used to use 2-pass as well, but seeing how fast first pass is a lot faster than a regular pass and doesn't result in a noticeable quality drop, it's like getting 2.9-pass quality at 2.1-pass encoding time, so to speak. That's why I switched to that mode.

[charleski]

Yeah, the commandline shown in the interface isn't right when in 3-pass mode, but I generated some jobs and looked at the XML - it seems fine to me, so the actual commandlines passed to x264 appear correct.

Vaguely related: Fast first pass doesn't seem to disable some of the newer options. (I have no idea which could be appropriately disabled.) A recent encode with b-rdo, trellis, adaptive quant, and b-adaptive, seemed to have almost exactly the same framerate (from a pre-filtered lossless video) between passes.

It might be worth going back now that so many new options are available and testing again for minimum lossage.

[charleski]

That's interesting. can you recreate the job that caused this behaviour and post the XML? (If you close MeGUI before executing the jobs they'll be saved in the jobs folder)
Certainly I've always found 1st-pass turbo to run about 4 times faster than the 2nd pass.

[foxyshadis]

I keep all old jobs around (no particular reason) so I just pulled the xml. The settings all show up there, but that depends on if b-rdo is even activated for subme 1 and whether trillis is activating.

[Sharktooth]

for what concerns turbo mode the (in theory) b-rdo can be "disabled" as well as mixed-refs (not sure about trellis).

I'm still struggling to get MeGUI compiled for .NET 1.1. Could you take a look at this environment Sharktooth and see what I'm doing wrong?
Here are the environment variables in the command shell I use to compile:

Or just post the environment variables you use so i can compare them.
Thanks.

Any chance that the Avisynth creator to support more than just DGIndex files? My reasoning is I have some DV-avi files I would like to encode using MeGUI and sometimes I have a rather large batch of them and it is very tedious having to create an avs by typing. Even if we could get a generic "Direct Show Source" template would save me a great deal of time. Would this be difficult to implement Doom9?

[charleski]

Yeah, I was thinking of adding in more functionality for the avs creator along with a couple of other enhancements I've written. Give me a couple of days.

[Kostarum Rex Persia]

Question for MeGUI developers: is it possible(in next builds) to introduce AVI and MPEG2 input in MeGUI? (curently,only AVS input)
I don't have knowledge,nor time to learn Avisynth scripting,so I be very delighted if you,guys,make MeGUI more friendship for use.

[charleski]

Well the best way to do that is to modify the avs creator as acidsex described so that it can accept avis and modify the DGindexer so that it will accept mpeg2s. It would be a mistake to remove avisynth from the input stream.

[Kostarum Rex Persia]

Great,but when I may expect new revision of MeGUI with MPEG2 and AVI input.Until new year,or perhaps sooner?

[Sirber]

Invest the asking time to some coding Shouldn't be hard adding that to MeGUI...

[Kostarum Rex Persia]

Ok,but from where to start.Can you advice me,Sirber.

[Sirber]

1) http://msdn.microsoft.com/vstudio/express/visualcsharp/
2) http://www.rarlab.com/rar/wrar351.exe
3) http://forum.doom9.org/MeGUI-src.0.2.3.1b.rar
3) Extract the sources
4) Open the sources with C#
5) Find the input manager class and add your stuff
6) Post your modifications

[charleski]

I'm writing the code right now actually , but I have a few other bits i want to add as well, so give it a day or two.

[edit] BTW, I'm blind, MeGUI can already import MPeg2 files in the d2v creator and automatically pass them to the avisynth module.
