Xmpeg vs Gknot

[Jas113]

hey! my question is why should i switch to Gknot when Xmpeg/FlaskMPEG does REALLY good quality rips. I ussually do 1 pass 1800 bitrate but i recently started using 2 pass. Does Gknow really give me a lot of advantage. My other question was what does PE enchancements and Bidirectional Encoding really do in Divx 5.02, Are thry worth using. Thanx :)

[Selur]

The possibility of a encoding queue and the endcredit handling migth be a good point to use Gknot,...

Hi there!

Jas113....the answer is easy! Try Gordian Knot and you'll realize the diferent. Gordian get the best quality rippins.

I did a lot of movies using a lot of rippers (and whe I say a lot...they are a lot) and actually I only use Gordian!

[theReal]

The resizing filters make the difference - XMPEG doesn't have as good resizing filters as avisynth (which Gknot uses).

Bidirectional is worth using, absolutely. The psychovisuals are very subtle and unless you want to make a lot of trial encodings on every movie, just leave them off.

[Jas113]

should i use certain filters or settings that i am not using because the image is a bit , well not as sharp as when i use xmpeg. Thanx

[Jas113]

and i just notices as iu was watchin the gordian knot rip that the IMAGE looks interlaced but Xmpeg said that it was progressive and the trailers were interlaced, when i did the xmpeg rip it didnt look interlaced, what should i do (there are 3 different ways to deinterlace in Gknot, which one can i use for everything (anime and live action))

[DJ Bobo]

There is no "one for everything"
Anime, if properly telecined, have to be IVTCed (= Inverse Telecine). Examples of non properly telecined Animes are Evangelion & Trigun. Don't even think about making a DivX rip of those, just do interlaced (X)SVCD out of them.
Other things (normal video) have to be deinterlaced normally.
Some Animes & most movies are already encoded in FILM mode, which don't need anything but checking "Forced Film" in DVD2AVI.

Read the guides and make a search about IVTC in the forum, these things were discussed long enough.

[Jas113]

i also relized that i dont resize much, i either leave it at 720x480 or i crop the bacl bars off so its something like 720x400. I always use a really high bitrate so it looks good (1800 ussually)

[DJ Bobo]

leaving the original resolution is also ALWAYS false if you're encoding to DivX, since for DivX you have to resize to the correct aspect ratio.
Here again read the guides for more information!

[Jas113]

what does force film do? and what should i use for deinterlacing? the area based filter for vdub?

[Jas113]

and after i IVTC anime ,do i need to deinterlace them

[Jas113]

Also, I set Xmpeg to 1:1 Divx Ratio, but i sometimes play them on my TV via tv out. Wouldnt that make it ok if i used something like 720x400 res?

[eXistenZ]

I use Xmpeg because:

1) it makes a really good and simple job

2) I encode *w/o* ripping 4 or 7 GB vobs on my HD
(I've only got a 20 GB on my notebook)

3) I don't care about resizing, because I make it done by the DivX codec, not by Xmpeg

4) the GKnot calculator is excellent, but I've written my own for use with XMpeg

5) I don't care about audio, because I use BeSweet for that and Nandub for muxing (dual-audio, of course ;-))

Issue 2) is by far the most important for me...

Bye, eXistenZ

[drizztcanrender]

what should i use for deinterlacing? the area based filter for vdub?
Well if you are going with the gknot method,you have a lot of other really good deinterlacing filters that work in the YUV color space and not in RGB like vdubs.That will save you a lot of time.Try using decomb,that's what i use and i think it's great.

2) 2) I encode *w/o* ripping 4 or 7 GB vobs on my HD
(I've only got a 20 GB on my notebook)

Well you should know that the open dvd function of these programs are probably killing your dvd device.You shouldn't use them really.Imagine your dvd working full for the whole ~8hours of the encode!!(sorry about the time but you said you have a notebook so i presumed it had to be a lot :))

Issue 2) is by far the most important for me...

It should

[mnd]

After some Knot attempts, I gave up it because it is too complicated and time consuming without noticeable better results for DVD conversion in my opinion.

Moreover with Knot I have some issues with audio and subtitle synchronization I don't have with Xmpeg 4.5.

I use always Divx 5.02 Pro 2 pass with GMC and Bidirectional encoding and use the Divx4 bit rate Calculator of Spark ( http://spark.hit.bg/divxcalc ) for Bit rate and resizing purpose with full satisfaction.

However Xmpeg has some bugs or issues which can daunt the newbies. For them
I have summarized my Xmpeg 4.5 experience in the topic "Tips and Tricks for Xmpeg 4.5" you may refer to this forum at http://forum.doom9.org/showthread.php?s=&threadid=30907

@Selur: I encode the end credits with the 1 pass quality based option and the main movie with 2 pass encoding, using Xmpeg and this job thing it has.
@theReal: Why the Xmpeg resizing filters aren’t good? I mean they deteriorate the quality or just the speed of the encoding?
By the way I do have problems with interlaced movies using Xmpeg. There is the option to use nandub and deinterlace filters after encoding the DivX, but I’m not satisfied with the idea. Is there anybody that actually encoded interlaced movies and deinterlaced them with xmpeg? If there is please help.

I have, unfortunately for you, no experience of deinterlacing because, up to now, all my DVD (Pal) are not interlaced and my TV captures in MPG2 are automatically deinterlaced by the soft of my ATI All-in-Wonder board and well processed by Xmpeg.

But for issues with Xmpeg you may look at the official Xmpeg forum at http://forum.mp3guest.com/. Perhaps one deinterlacing experienced user of Xmpeg may answer to you.

Regards

[yokotsoko]

I had no idea that there was a forum specially for xmpeg. That may prove very helpful. Thanks:)

[Koke]

Maybe its time for mention (while this "VS" stuff still goes on"
another great encoder, Vidomi.
I left GKnot (complicated) and Flask (buggy)
and now stick to Vidomi. It is great encoder.
It uses DivX5.xx perfectly. You do not have to set
bitrate at all. Just fill in output size.

What is your experience?

[yokotsoko]

I haven't even heard of vidomi. Maybe it's time to change Xmpeg but I really don't want to use Gknot.It would take ages to learn all its options. Are there any guides for vidomi and anyway does it support deinterlace? It seems that most the DVD's I come across are interlaced

[Koke]

Website is at:
www.vidomi.com (http://www.vidomi.com)
My guide (you can try others at Vidomi site too):
Koke`s Vidomi Guide (http://www.inet.hr/~dkokeza/xvid)

Its a simple guide for a simple proggy but you will be amazed
with results.

[yokotsoko]

I'll try it out.
Are there any other filters or programs worth downloading for vidomi or I only have to download the installer?

[Koke]

codecs:
XviD or DivX 5.02

ffdshow filter for playback (optional)

[yokotsoko]

vidomi is good, mkay?
It's a lot better than xmpeg. And it's very easy to use. I liked it. Just a question: when encoding with YV12 the scale filter type is greyed out. Is this a bug or something? In RGB mode it can be changed though.
Anyway thanks for the tip Koke. I'll be using vidomi from now on:cool:
P.S Well I have another question.
What is this threshold thing under hypercrop and under Blend in the Video options? What does it do and is it better to be a small number like 5 or a big one like 30?
And what exactly is Blend?
