any good encoders for the PSP to make MP4 files ?
 

Okay i dint know quite where to put this enquiry so apologies in advance for being in the wrong section.

Iv just bought a PSP with a 2gb card and been trying to get movies on there. DVDs to PSP Mp4 format

So far iv been using PSP video express and ImToo PSP. The quality in not fantastic, both converters only do constant bitrate (IM too has a 2 pass feature that when selected errors & fails the conversion which makes it pointless).

for a 2 hour film you need bitrate of between 502 to 768 kbps, the out put file is then between 500 to 640 mb. And even at that birate the quality on fast seens is pixely and nothing compared to original UMDs.

Here are my questions

1. Does anyone know of any good encoders for the PSP to make MP4 files ( the offcial sony one is supposed to be crap)

2. Are KDVD or KVCD paramaters possible on PSP for good quality video and to save file space?

3. Any information or any links for sites that help you do good quality video conversion? ( iv tried a few but these have been all basic sites with just basic conversion, output files are questionable)

4. Does anyone have any idea what converters is used for UMd movies?

I just want to say thank u in advance for anyone that helps me out, this site has always been my video conversion resource and bible

Hi khusru,
I never tested it to encode for PSP, but you could give MeGUI a try. It can use x264 or mencoder to encode the mp4 stream, and supports profiles. I read it can encode very well for PSP (I think it even has a profile designed for it).
If you test it, tell us how it was.

thank u so much, i will definatly give it a go and get back to you, the encoders that i tried that are specifically designed for psp tend to give results that are not up to high quality unless you turn the bitrate to max and get an enormous file size.

but i will get back to u on how it went

Yep. Try MeGUI, as it already has a preset (PD-PSP) for PSP machines.
Does PSP allow MPEG-1 :?:
If it does, then you also know what you can try ;)

im not sure if it allows mpeg 1, as far as im aware its only mp4, i will try it though. I know that with some software hackson the machine it can play avi files as they are with no need for re encoding,

okay im trying out Me Gui, it takes avisynth scripts. Iv never done a script for PSP encoding so i used one of the avi conversion ( with changes) scripts but i keep getting incorrect destination frame size error when i open it up.

Heres the script
:
AviSource("D:\Mpegs\psp\test.avi",false)
BlindPP(cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
GripCrop(320,240, overscan=1, source_anamorphic=false)
GripSize(resizer="LanczosResize")
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
GripBorders()


Is this script alright for PSP video conversion from avi file,

how can i sort the error problem, iv tried changing the 368*208, 400*192, im using these frame sizes as these are the ones given with the psp video programs


Thanks guys

Forget GripFit :!:
Use manual resize.

Edit: Maybe we can convince Incredible to add 320X240 in PARanoia :idea: :cool:

-kwag

sorry kwag i have never done a manual resize, how do i go about doing this?

I meant using BicubicResize and Addborders in your script.
Look at PARanoia or FitCD, and look how it generates it.

-kwag

this is going to be a first for me as i have never used bicubicresize and add borders, is there a section on the site that explains this at all,

p.s thats the first time iv heard of paranoia, had a brief look at it, is it a program that creates avisynth scripts via a gui interface? or have i got the wrong end of the stick
thanks again

http://www.avisynth.org/Resize There's a PARanoia section in the forum here. It does generate .avs, and the resizing can be BiCubic, Bilinear, etc.

-kwag

Thanks kwag, read into the resize stuff. tried out fit cd
basically i loaded up my avi file into it, changed the out put setting to 360*208, and then i copied and pasted the avisynth section into my script like so:

AviSource("D:\Mpegs\psp\test.avi",false)
BlindPP(cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
BicubicResize(464,272,0,0.6,10,0,636,272)
AddBorders(8,152,8,152)
#Trim(0,187921).FadeOut(150)
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)

The script loads up now, Does this look alright? Is there anything i need to take out or put in for good quality psp conversions? i want to keep 16:9 aspect

Get rid of overscan, because you're not using a picture tube :!:
So recalculate your resize again without overscan blocks.

-kwag

okay mate, found this other psp program, with a psp script using lacsoz resize, keeps the aspect 16:9

this also works:

AviSource("D:\Mpegs\psp\test.avi",false)
BlindPP(cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max =3,variance=0.1,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
LanczosResize(368,208)
Undot()
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
assumefps(29.00)

im going to use the above script as when playing back there are no borders just the 16:9 video played at the right size. Iv downloaded MeGui, u guys mentioned a psp profile (PD-PSP) on it which i can not find. is it just the mp4 setting and i change the put put details, bitrates etc? or is there an individual profile for psp, how do i access this?


edit:
just found the profiles pack which includes pp psp, thanks again for all your help, going to use megui, with mencoder and above script, will let u guys know how the tests went next weekend

khusru,
I advise you to also try x264 encoder.
I think it supports further parameters and tweaking than mencoder.

i cant for the life of me get megui working properly.
first i downloaded me gui and all the necessary additional apps to get it working correctly ( mencoder, x264, mp4 box) 1 pass i got mp4 file with no sound, 2 passes ( and all variations) some time i got mp4 file that was 0 kb, other times i got .stats file, other times after the first pass it will stop with a warning ( the memory cannot be read etc ).


then i tried just x264 full package on its own, with the two pass method i get either a 0kb mp4 file or a stats file, please help this program has been doing my head in for the last two days.

is there a page that runs u through the set up of this app

mistake

on automated two pass using me gui x264 encoder i get an mp4 video file thats about 700kb ( seems correct as its a test clip) but its just a black screen

Did you try at doom9 forum, where you downloaded the application from?.

You also didn't get audio working, isn't it?. Are you encoding he-aac with Nero?. Do you have Nero files to encode with?.

The 700 kb file, how long is it?. What are you using to play it?. Can you play other x264 files properly? (sagitaire posted a sample somewhere at KVCD.net).

Can you post the command megui is generating for your .avs file?.

Silly question... does your .avs file play well in mediaplayer?.

I guess he has audio. Sometimes when the video codec only is missing, the player opens and ply the audio, letting the video black.

Kushru, you need the last ffdshow release. check that.

You're right, Phil, maybe video is there but he's nor playing it.
That's why I asked if he could play sagittaire x264 test file, to see if right codecs are installed.
If not, it will also be of help to take a look at the command megui is generating.
