PMP Mod v2.02 & PMP Mod AVC v1.02

[604000]

Hi guys, i've been doing tests ripping LOST from the original .vob into an average output bitrate of 700 kbps. I used Gordian Knot and the file works fine with PMP Mod, the only problem is that in some scenes the reds and other dark colors seem to be blurred. I'm sorry, i don't know how to explain it (my english isn't great). I thought it could be the resize filter, so i tried bilinear and lanzcos, but the problem is always the same. In the low motion scenes it works perfectly, but when the camera is moved faster then this king of "ghosts" appear again.

Tomorrow i will try the sharpen filter, but i just want to know your opinion.

Thanks!

Can someone please post the overall "best" encoding settings so far? By "best", I mean something that looks nice, but doesn't take too long (something around 2 passes, perhaps), and can be used to fit 2 hours of footage on a 1GB stick.

Thanks.

[Alcahest]

Is there any plans to support framerate 29.970?
For now, all my tries have given watchable video but skipping sound.
See you!

I've updated my findings on PMP format encodings and compability with PSP.

Here's samples:
IslandFever3.DivX.q3.pmp
IslandFever3.DivX.q2.pmp
IslandFever3.DivX.q4.pmp
IslandFever3.DivX.vbr1300.2pass.pmp
IslandFever3.DivX.vbr1000.2pass.pmp
IslandFever3.DivX.vbr1500.2pass.pmp

Source: HDTV
Resolution: 480x272
The rest can be "read" from the name of the file.

After my *personal* opinion, I would recommend using CQ3 or (even better) using at least 1200kbps VBR 2 pass (preferably +1300).
There are *really* many reasons why I chosen lavc over any other codec and why I've chosen the settings I've used (even their order).

I'll post my settings tomorrow. Off to bed now... Until now, feel free to comment on these encodings ;)

Hi wooolf - Welcome back.

I'd like to see some results with your settings preferably at 25fps and using a decent trailer that tests the codec.

File sizes are great in your encodes.........until you realise the source doesn't actually test any bitrate barriers. There is so much slow panning and half speed film in the original source - its difficult not to get small files or hold on to detail.

You might want to highlight the content also - although soft - I'd guess there are loads of young ones reading this thread now PMP mod has done the rounds at most of the PSP sites. LOL

=========================

@RATiX

Virtualdub - 2pass 3ivx encoding gives realtime or faster encoding on most modern PC's. For 2hrs on a 1gb stick - this will easily cut it in less than 4hrs with very good results.

All the best

1) Thank you =)
2) The last ones I've posted are encoded @ 25fps (source was over 50fps).
3) Thanks. Also for comparing to "fast scenes" read my previous posts, I've posted lots of DiVX encodings of Matrix 2 scenes #15 and #20.

The latest encodings of IslandFever3 were made just to show that blurred/softened videos does look as good (IMHO) as videos with fast movements (as in Matrix 2).

Also as said, I'll post my settings today when I'll get home, then you can try (if you are interested) "my way", =)

@ wooolF

Your quality is really good. I'll try your method when you'd post it. Only one question, the encoding method is the same for these samples of Island Fever than in the Matrix scenes? I thought that with XviD the quality was better, but I’m thinking on trying with DivX instead of XviD.

I've testing Xvid multipass @ 750 Kbps. A file of 40 minutes is about 240 mb and the quality isn't as good as I thought. I hope that the blurred movements in the fast scenes would disappear with the rip I’m working on.

=)

[604000]

@ xxxstarmanxxx

Only one question -- maybe so obvius for you. Using your method, is possible to configure the avs script to process two .vob toghether or is it better to process them separately and then merge them?

The samples you posted a few days ago are great too and and with the amount of fast scenes you posted it's perfect.

Thank you :)
Depends on which Matrix scenes you're referring to. I've posted the "orgasm cake" scene and scene #15. One of my latest previous posts had a DiVX encoding of scene 15 (look back 2-5 pages). The XViD encoding of same scene is not acceptable because of audio stuttering problems. Qualitywise I got DiVX encodings nearly as good as XViD. Gotta find the "Golden middle" you know between quality and all the problems we're having.

As for xxxstarmanxxx's latest encodings... I'm not happy about 3ivx (or whatever it was called), the other encodings were *way* too sharp. Also dark scenes had lots of blocking which is not acceptable for me either. basically, I'll use some more space but I want best possible qiality that I can get without all those problems as audio stuttering, ghosting etc.

I'm afraid you'll just have to live with the ghosting. The PSP screen has a terrible refresh rate and nothing can be done about that. You can also see it in games, although it's not as easily spotted.

[wooolF]

pspdev can post porn????????m does it .................

It was just for educational purposes to show the quality... Also it's as "soft" as it can get and only 1 min. I doubt anyone will be jacking off to that clip...

[604000]

@TestType

Thanks for your answer. I was thinking about that but when I saw the Matrix trailer and other videos with much more motion I thought that it was a problem with the encoding I made. The video looks perfect in my computer, but then with the psp it's not as good in some scenes. I think that LOST hasn't as fast scenes as other trailers I have seen here. Maybe the background is too much detailed and for that reason the screen doesn't show it properly. However, I'll try with diferent settings.
----

I've been trying the 3vid codec too, but the file that generates is not posible to open, even from windows. Furthermore, I didn't found the way to restrict the fps on the result file. Now I'm at work, maybe later I'd continue trying.

And about the sample of Island Fever, I've been watching this again and I think that the image doesn't load as fine as with other videos, even trying with the smallest file. Well, I'm not an expert, this is only my opinion.

I'll try to post some samples and maybe a guide with Gordian Knot for beginners like me. =)

Doesn't load as fine? What do you mean? Could you try to express it in another way? I'm not right sure what you mean :)

@604000

Yeah, fast action would usually trigger it but I sometimes see it even in somewhat slow paced scenes. There are probably various factors that can bring it out, certain color combinations for example.

But I did a few checks with my Spider-Man 2 UMD and it's not nearly as bad as even many high quality pmp videos I've seen. Even Eingang's 11 pass high bitrate Riddick clip has visible ghosting (when you see the black priest walking in town).

So maybe there is a little more to this than simply blaming it on the screens refresh rate, although it certainly is the reason you see this annoying effect.

Ghosting (daub/grease) is caused by the reaction times of the display. It has nothing to do with bitrate or video quality. It affects dark parts in bright places. UMD Videos are very bright or there is some other picture adjustment (gamma/contrast/balance etc.). I set all videos to 4x luminance with pmpmod and ghosting disappears nearly completely.

[604000]

wooolf, I was trying to say that the Island Fever sample doesn't play as smooth as other trailers with much more motion. I downloaded the VBR.1000 two pass file. The quality of the image is really great and it looks pretty good in almost all the sample, but I think that there are a few scenes played in low motion camera that could be softer --I'm not talking about the quality of the image, I'm referring to the fps in this slowly parts. Do you understand what I mean? I have files @750 and I don't have this problem.

Maybe that's caused by the VBR or because the original file has the same effect and it's not an encoding problem --sometimes this low motion scenes aren't as smooth as the rest-- but that's not normal if the original file is a .vob.

I'm only interested on bitrates between 700-900. In my opinion higher bitrates aren't useful for longer files unless you have a 2gb memmory stick. The best results I had until now have been with GK and Xvid. I will try adding the sharpen filter in the avisynth script but with a value lower than 1. I think that with a lower value xxxstarmanxxx's samples wouldn't look too sharp as you said. For that reason I told you that I think that there's something wrong with scenes, I use lower bitrates and it shouldn't happen in files with higher quality like yours.

I hope you understand me better this time. ;)

Eingang, I will try changing the luminance and the contrast of the original. Thanks!

[wooolF]

@604000
It's because it was encoded from HDTV... The result you have described happends to me only when I work with HDTV material and I guess my box just can't handle it (even after it's a 3.5ghz P4). Matrix scenes (which had much more action and come from my retail DVDs) always been smooth.

Why process 2 vob files ????

Why domt you just rip your source as 1 complete vob file???

I would/could only do this if I wasn't using an NTFS - Who doesn't use NFTS???

Are there still windows me/98se out there????

Rip your vobs as 1 - No problems
=====================

@all

Dont jump on wooolF's back about the recent encodes - I was just pointing out that there are younger audiences here - and maybe a note about the content might help. - His work is very valid here........

@TestType

Totally true statement - test your encodes first in windows before you mux and you will see the TRUE quality you have achieved.

=====================

quote......Maybe that's caused by the VBR or because the original file has the same effect and it's not an encoding problem --sometimes this low motion scenes aren't as smooth as the rest-- but that's not normal if the original file is a .vob.

HDTV encoding takes far more cpu power than you think - I wouldn't work with such encodes outside of dual core CPU's - as it normally results in bottlenecking of the video bitrate which causes stuttering in the panning of scenes..........no matter what settings you use. Thats why you see inconsitant quality is HDTV encodes on lower power machines.

I have an Athlon 64 3200 - And would't try HDTV @ most bitrates -

All the best

Current encoding setting available via codec as follows under PMP Mod:

DivX:

Insane quality: yes

Quater pixel : no

GMC: no

Noise reduction: any

Psycho Enhancements: any

Quant: h.263 or h263 optimized.

=====================

XviD

Adaptive Quant: no

Quarter Pixel: no

VHQ: any

Chroma Motion: yes

Turbo Mode: yes

===========

3ivx

All these setting assume a bitrate equivalent or less than 20000kbs in any mode are are playable by PMP Mod - regardless of bitrate condition or filter selection (internal - RGB or external YUV colour space).

May the tests begin.................

I hope that helps

@ xxxstarmanxxx

You didn't understand me about the two .vob encoding. I wanted to know the way to set up the different .vob's of a film to be processed as one in the avisynth script --to have an output avi with all the film toghether. You put the location of your .vob like this "DirectShowSource("X:\myvob.vob")" and I was trying to encode all of them as one. But forget about it, I don't make my own scripts but then I saw that Virtualdubmod can open directly the .avs created with Gordian Knot. Then it was easier to add filters keeping the settings configured in GK. That's a good way for beginners like me. =)

About the computer, I didn't know that this effect was caused because the computer wasn't powerful enough. It's good to know it, I'll leave the office's Xeon working during the night, the difference betwen the Xeon and my home's computer is incredible.

PMP Mod v1.02

- A part of the color space conversion is done in parallel with audio decoding, speed increase around 2.5fps

malloc / Raphael version will probably follow shortly ( i hope :P )


yesterday i've got the datel hdd, i'm now working to align performance on differents memsticks/hdd


@all:
i ask everyone to use only movie trailers / perfectly legit content (no movie snips, adult content or similat stuffs).
this is to avoid any kind of problem and is a form of respect to me (and i think the other users).
you are all free to do what you want, until a mod jump on you.
i'm also free to no more follow this thread too, if this go on

If I understand you correctly - You have a number of vobfiles om your hard disc as follows:

VTS_01.vob 1024mb
VTS_02.vob 1024mb
VTS_03.vob blah mb

Which make the total film output of - say 1.52mins.

IF SO - You're ripping yor DVD's incorrectly - You should be ripping them as a single vob file in a ripper so you have the following:

VTS_01.vob 3.65gb - 1.52mins

Hope that helps

==========

Yay for jonny!

Agree with source encodes staying within 'legal' boundries - Lets keep the thread free from trouble.

If you have something to share that oversteps the mark or is a full encode (for testing purposes) - maybe try sending an instant message to parties concerned for the link.

Jonny - Where will you be If we need you????? - will there be a new thread thats DEV only - free of all our encoding spam?????

===============

Also heads UP! - A new version of pspmpverter!!!!!

@xxxstarmanxxx

Personally, after your recommendation and after doing a few comparisons of my own, I'm going to stick with 3ivX to encode from now on.

While Xvid appears to give better, sharper images when the picture is paused, it seems to show more ghosting than with 3ivX with moving images. This has become quite an issue for me as I was starting to feel like I was getting eye-strain while watching Xvid encodes.

It may be my imagination, but I think the reason for the difference in the amount of ghosting seems to be caused by the fact that Xvid seems to darken and more heavily compress dark areas of the picture - not good on the PSP screen. 3ivX seems to avoid this.

My only current problem is that I can rarely encode a file at more than 200k (as shown in the 3ivX settings - the final files have an avg. bitrate around 1400kbps) without getting audio stuttering.

[wooolF]

As promised...

My guide/tutorial for converting DVD (and other normal files) to PMP at best quality possible (works for me) avoiding the usual audio stuttering and ghosting problems. Basic usage, nearly "1 click mode", 1 application used that you will "work" with.

I Agree with you jonny, that use only movie trailers / perfectly legit content (no movie snips, adult content or similat stuffs).

[reveine]

Awesome!! Jonny! Cannot thank you enough for your hard work.

About the "speed increase around 2.5fps", does that mean we can now try encoding at 29.97fps?

[k0nan]

jonny
Great job on the update!! I've already noticed that PMPs that had audio stuttering with the previous versions now play stutter-free! Many thanks!!

wooolF
Great work on the guide! I'll have to look at it more in-depth tomorrow. I see you've chosen 1300 as your king, I thought after your Matrix2 scene16 encode that Q3 would be your pic, but I trust your experience. Do you force 480x272 as your output ratio regardless of your source ratio? If not, how do you go about calculating your output ratio? I use PSPMPVerter solely to calculate PMP aspect ratio b/c I haven't found a similar feature in Winmenc yet. (edit - nevermind, I see that you use AMV Resize)

btw the scene20 encode you made me now plays flawlessly on jonny's 1.02 update. :)

Hello mate - Your findings are spot on regarding the black level compression in dark scenes using XviD. I think this is why it normally comes out with the lowest file sizes in all of my tests - But like you - I cant live with the ghosting it introduces in its attempt to give very good detail.

What I have found with the 3ivx codec is it attempts to compress the whole scene to Above DivX quality and somewhere around XviD sharpness.

For me - that makes it my current codec of choice until we can introduce some of the enhancements in the XviD codec without any stuttering side affects.

As you can see - Jonny is working hard on optimizing - the player is getting more robust with every release - And I dont think it will be too long before we manage to get most of the quality/compression settings active using XviD.

Till then I'd stick with 3ivx.

All the best

jonny Hey many thanks and keep up the great work!

wooolF Thanks for your guide, will test ond give my feedback. Also, I for one missed you on the board...It got kinda boring when you where away.

miemt11 Thanks for all your hard work on this project man. I have found myself hooked on this board...checking almost every 1hr for news and stuff...definitely and addiction :) I hope all works out ok with your family stuff!

[miemt11]

Hmm, are the matrix 2 scene of orgsm that have sound problem. still available to download. I wan to test it on PMP 1.02(Jonny) or other people already tested, please post you comment
