@psp360

Yeh, I'm waiting for responce from 2 people more and then I'll post the way I do it (be it the "wrong" or the "right" way) =)

A got problems getting correct aspect ratio when converting widescreen videos (608 x 256, for example). I choose to convert to 480x272 and get vertically stretched image. What am I doing wrong?
P.S. I'm using latest Videora relase but the same happens with PMP Simple.

Problem is the source you used 608x256 is 2.375:1 which is not the same as 480x272 (1.765:1) - so instead of encoding them into 480x272 you sould try 480x202 w/ top & bottom black bars - or 480x200 w/o top/bottom blk bars.

k0nan · Post by **k0nan** » Thu Jan 26, 2006 7:21 am

Fxp - 272>256, so you're streching the vertical by not keeping the aspect ratio intact. 608x256 should be rescaled to 480x200 to keep the proper AR, you can then zoom later on in playback to your preference using malloc's mod. Try PSPMPverter .9.1, it has a great AR calculator.

jo2k - he wouldn't want 480x202 because 202 isn't divisible by 8.

Search for the OSD/SUB fonts in an alternative di- rectory (default for normal fonts: ~/.mplayer/font/ font.desc, default for FreeType fonts: ~/.mplayer/ subfont.ttf).
NOTE: With FreeType, this option determines the path to the text font file. With fontconfig, this option determines the fontconfig font name.
EXAMPLE:
-font ~/.mplayer/arial-14/font.desc

woolf - matrix quality was sweet. The LCD "ghosting" is a pain I know - although compared to AVC at 368x208 or 400x176 zoomed I aint complaining!!!

I have been trying various filters on some test scenes of my own, I would be interetsed to hear what filters you have been using. For information I have been experimenting with LimitedSharpen and XSharpen both with Udot.

Some interesting results even with bitrates down to 800kb via xvid (always 2 pass).

Cheers

Ok here goes, my matrix playback test results.

1 Gig Fast SanDisk
----------------------
If played from start to finish with no searching, no audio skipping apart from a tiny bit near the end.

If I then search back and forward, parts that didnt audio skip before now do so.

2 Gig Slow Sony Stick
--------------------------
Same as above but audio skip was just a miniscule bit more.

Tried on original 1.01 version of PMP Mod.

It seem the source code could be a good place to try and improve things here aswell as encode settings.

I would love to try your settings on my own problem source material. Please share dear chap.

What's the meaning of harddup?And how can i put subs using mencoder?

harddup
Only useful with MEncoder. If harddup is used when encoding, it will force duplicate frames to be en- coded in the output. This uses slightly more space, but is necessary for output to MPEG files or if you plan to demux and remux the video stream af- ter encoding. Should be placed at or near the end of the filter chain unless you have a good reason to do otherwise.

Ok thanx and as for including subtitles,how can it be done using mencoder?

Code: Select all

	-sub <subtitlefile1,subtitlefile2,...>
	Use/display these subtitle files. Only one file can be displayed at the same time.

That should be enough... as said, I tried with 2-3 encodings with subs, all worked fine... I haven't invistigated more into that area... Try to look here for all available filters for the subtitles

As I do my encodings only with mencoder, I'm limited to mencoder xvid video filters. They can be found here : http://www.mplayerhq.hu/DOCS/man/en/mpl ... ER%20ONLY) (under xvidenc (-xvidencopts)). Some of the filters I've used are : vhq, chroma_opt, quant_type, qpel, unsharp etc =)

@wooolF:
Regarding your matrix encodes, I did a quick test with profiling enabled on the video output and found that with your videos (I tested the 768 and 1200kbit versions) the CPU stalls are much higher than with any other video. This alone isnt enough information, but it's a start of what to look for when optimizing. Have to look more specific at different functions to find where these stalls occur (most probably deep inside the libavcodec, so this will be ugly to find and optimize :().

Hi all - Still testing - but I've given up on Xvid for the time being.

Switching to avisynth scripts with Divx 6 codec.

My current script test is as follows for anyone who's using Nic's_DVD2AVI mod.

---------------

LoadPlugin("C:\Program Files\DVD2AVI_NIC\System\DGDecode.DLL")
MPEG2Source("E:\test.d2v").Crop(4,16,712,548)
Lanczos4Resize(480, 272)
Sharpen(1.0)

---------------

I seem to be getting some decent encodes with Lanczos4 - much sharper filter for Divx + adding max sharpening.

Will try and upload a 768 and 1200 of Blade Trinity trailer vob sometime this morning.

Keep up the good work everyone.

Oh yes, frameserving via Avisyth is super solid! I encourage all to try and learn to use avisynth.... its really simple (esp for programmers who are comfortable with writing scripts).

However, using DGDecode for DVD encoding is a bit painful for beginners as the DGDecode does not fix the aspect ratio (the video is stretched slightly vertically) of its d2v output.

Does any DGDecode expert out there who knows how to detect the correct aspect ratio? As a workaround, i use the now defunct FlaskMpeg to detect the aspect ratio, and then i resize the video to the correct aspect ratio in the avisynth script.

Man, Read the Thread name (it's PMP MOD 1.0x here !)
No, RV9/10 aren't supported.
Actually, jonny preconize XVID/DIVX only.

using Gordian Knot detect the correct aspect ratio

avisynth script like this

DirectShowSource("your-clip.avi", audio=false)
Lanczos4Resize(480,208)
AddBorders(0,32,0,32)

Seems you've tested my XViD encodings, I gave up with XViD for now and using DiVX (see my signature for DiVX encodings).

xxxstarmanxxx · Post by **xxxstarmanxxx** » Thu Jan 26, 2006 8:04 pm

Hi all.

Please test this XVID file if you have time.

If feedback is what I think it will be - I'll post a guide.

File encoded with an avs script with crop/resize and 1 filter - 2 pass - Total encode time 9 mins.

Blade Trinity XVID 2000kbs PURE encode. (averages 1921kbs)

File plays fine - NO -audio/video issues - And I think its far better than my DivX 2000 encode.

http://download.filefront.com/4669217;1 ... fcd266f720

I think this is my best encode to date and is 1 mb smaller than my Divx encode - but has much more detail!

I know I said I had given up on Xvid - But I couldn't resist the challenge! - Glad I persisted!!!!

I'll spend a day or two trying to get this trailer down to around 20mb without any noticable loss - but for now - this is my benchmark encode.

All the best

J.

Hello mate.

I'm doing these tests on a sandisk gaming yellow 1gb at the mo.

Latest version of Malloc's mod in line with pmp mod 1.01 and the 1.02 muxer.

All going sweet - just got to do some adaptive tests to reduce filesize and see if the player can handle it.

All the best

by the way, what's the source? DVD? HDTV?

xxxstarmanxxx · Post by **xxxstarmanxxx** » Thu Jan 26, 2006 9:45 pm

LOL! hehe

Source is VOB

I dont know why I miss a line in posts - I do it on every board I'm a member of.

I think its because I'm not the best reader in the world - LOL!

The most important thing about this encode is Lanczos4Resize - It's a fantastic filter for VOB and HDTV.

All the best

wooolF · Post by **wooolF** » Thu Jan 26, 2006 10:01 pm

@xxxstarmanxxx
Lanczos4Resize is better then Lanczos (which mencoder uses) because of it's anti-aliasing... Too bad mencoder doesn't support that video filter :/

OK...Presently have a SanDisk 1GB with PMPmod v1.01

@wooolF your Matrix_R.divx.take16.pmp file run VERY VERY well, no audio issues and the vid quaily was super sweet. I must add that i could tell the difference in sharpness compared to if it had been encoded using xvid, but that is a mute issue as this video really worked well overall compared to the many issue audio issues we are facing with xvid.

I definitely want to get your guide on this encode. Great work!

@Eingang with both your files...7.pmp and 11.pmp I got and error:
"pmp_lib_open: can't read audio header" can you please give some help on this?

@xxxstarmanxxx Also excellent work! There is really no comparing ...xvid really makes the movies look alot better...that extra OUMPH does the world of difference. audio and video ran very good on my card did not have the ghost effect that was apperent in wooolF's vid but that was removed once you upped the brightness.

Gentlemen, I applaud all your hard work and welcome all info/guides so that I can then make a better informed decision on which method works best for me.

Well, your link only gives me a "File Transfer: Unavailable". However, I only use XVid myself, as it provides better quality than DivX and I'd like to get it work smoothly with PMPMOD :)

wooolF · Post by **wooolF** » Fri Jan 27, 2006 3:27 am

@xxxstarmanxxx
Watched your video... No rant, but it's WAY too sharp. It's just overdone with sharpness IMHO. It's like the movie consist of million of sandcorns... You overdone the sharpness imho =) And it's "edgy", which means that edges of the main objects on the screen aren't clear, but blurred. And the well known audio stuttering problem is there (at the end when Blade sais "I was born that day" and when that main vampire dodges the bullet). Average, disappointing quality for +1900kbps XViD...

@Raphael
Yeh, seems it got blocked on YouSendIt. I will reupload to another place tomorrow (not currently at home). And you should really lok intoDiVX (I know, I hate it myself, but that's the only option for now if u want a good looking video @ PSP with no audio stuttering problems IMHO).
