Megui x264 question

[king22491]

hi

im new to the concept of x264 encoding so i was wondering if i could get some help. I see in the input screen of Megui you have to browse for an avisynth script. i was wondering if you have to write the script or there is key to generate the script?? pls forgive me if this is a newby question.
thanks in advance

Grab a more recent build. You can then drag any supported file type onto the input screen and have the correct window appear.

[king22491]

so in simple terms you saying that files around the input scrn can be dragged in and the avisynth script should be loaded??

[Richard Berg]

I mean what I said. If you have a recent build, you can drag video files onto the input tab. If MeGUI supports the file, it will open the correct window for you.

If you want to access the AVS editor directly, it's on the Tools menu. There are many other AVS editors available as well, or you can use Notepad.

it didnt work. i tried drag a vob file into in then a d2v file and it wond input ??

You might be using the x264 MeGUI variant. If you aren't experienced with avisynth you really must get the full MeGUI.

I have a little question about MeGUI too - if option bitrate variance is % variation of initial bitrate, why the default value is 4%??? Say if bitrate is 1000kbit - for complex scenes give only 1040kbit and for low motion scenes is 960kbit??? In other codecs this option may be ~50-80%!!! Or in VBR mode this value not used?

Sorry for crappy english :(

@AlexB17: This might help:

Example: you want to encode a movie in 700 MB.

2pass: will get exactly 700 MB, and maximize quality.

1pass ABR, ratetol=inf: will get somewhere between, say, 600 and 800 MB. Whatever filesize it happens to produce, the quality will be almost as good as a 2pass encode of that same size.

1pass ABR, ratetol=1 (or the like): will get very close to 700 MB (e.g. 699-701), but will have lower quality than either of the above.source: http://forum.doom9.org/showpost.php?p=704099&postcount=23

...ratetol is not in any particular units. I tried to make it that a given value of ratetol produced the same %error in filesize independent of movie length, but of course longer movies will tend to average out closer to the target even without enforcing anything.

In practice (see some examples), it looks like ratetol=1 is about +/- .5% bitrate, so ratetol=2 would be about +/- 1%. (This does not, however, scale to very large values of ratetol: it converges asymptotically to some maximum variance depending on the content and other settings. ...source: http://forum.doom9.org/showpost.php?p=705225&postcount=25

Thank you!

ive been using doom9's MEgui x264. would you recommend i use just MEgui. Is there a quality difference between the two programs
thanks in advance :thanks:

[Doom9]

Is there a quality difference between the two programsIt's matter of what you perceive as quality. Visual quality, no. However, user quality, definitely yes, because the full gui has a lot more functionality, like audio encoding, muxing the end result, a one click mode, automatic interlacing detection, and a long list of additional features.

i just saw the poll

why do more people choose to use MEgui x264??

[king22491]

man this is driving me mad :angry: i have to input a avs file. I am asking how to create this avs file??

[berrinam]

Read Richard Berg's post again. It's very simple:

Get a new build of MeGUI FULL version.
Take your input file and drag it onto the main screen of MeGUI. The correct window for handling this file, whatever it is, will come up and you just set it up as well as you can. The options are well labelled, so read carefully, and you should be able to work it out.

[king22491]

it didnt work. i tried drag a vob file into in then a d2v file and it wont input ??

i did exactly what he said ,berrinam and it didnt work.

[The Link]

i did exactly what he said ,berrinam and it didnt work.
Did you set the paths for the needed external programs (dgindex etc.) in the settings (Tools--> Settings)?

[bugmenotwillyou]

I believe he is talking about the version available at sourceforge.net (http://sourceforge.net/project/showfiles.php?group_id=156112) (0.2.3.2024, Jan-14-2006). I just downloaded it and was able to do a drag-and-drop onto the input tab, which promptly generated the AVS file.

[king22491]

thanks "the link and bugmenotwillyou" it was a mixture of both of the problems you stated.
thanks heaps for your help
:thanks: :D

why do more people choose to use MEgui x264??Probably because it comes bundled with both b0bors and Sharktooth's x264 builds, whereas you have to download MeGUI on your own.
