PSP encodes using x264 and Megui; psp crashes dell, settings, programs, exactly

andy

A week ago i got a new pc from dell and in that time i havent dont any encodes, so i thought il get it set up today and start doing some conversions, i always start by using a short 7 sec avi clip to make sure that it works. But every encode i have done has crashed the psp with black screen or it says cannot play back file,
i am using exactly the same settings i used on my old pc, and all the same builds of the programs.

The mp4 video comes out fine i can play it back on pc, i then encode the sound in Besweet low complex. high quality at CBR 64kbps, src 48000.
I then mux using YAMB, and run it through atomchanger, get MAQxxxxx.mp4 and copy it to ANV folder on psp

Im using the pd psp profile from sharktooth

Heres the command line from me gui:

C:\Program Files\x264\x264.exe --pass 2 --bitrate 312 --stats quot;.statsquot; --bframes 1 --b-rdo --weightb --subme 6 --trellis 1 --analyse p8x8,b8x8,i4x4,p4x4 --direct auto --progress --no-psnr --output quot;C:\Documents and Settings\Khusru Miah\My Documents\PSP Folder\Scripts\a.mp4quot; quot;C:\Documents and Settings\Khusru Miah\My Documents\PSP Folder\Scripts\a.avsquot;

I cant work out what the problem is, thanks in advance for anyhelp

anyone?

HINT: The title should be PSP encodes using a NEW PC; psp crashes...

Well, it is kinda strange... Are you SURE the programs didn't change? Maybe you installed a newer version? Do you convert fps? If so, do you use nicefps?

the videos i have been testing on i havnt added any changes in frame rate because they are allready 23.976 fps.

heres my script:

AviSource(quot;C:\Documents and Settings\Khusru Miah\My Documents\PSP Folder\test.aviquot;,true)
Tweak(sat=1.2, bright=5)
Lanczos4Resize(368,208)
Sharpen(0.3)

finally got some working encodes. i ended up using a bat file posted by Gimpi, thanks mate.

The encodes work now, but i just had a couple of questions for 2 pass conversions

Heres the bat file:

start /belownormal /b /w x264.exe --progress --bitrate 312 --ref 2 --mixed-refs --bframes 2 --subme 7 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --no-psnr --output video.264 a.avs
start /belownormal /b /w MP4Box.exe -fps 23.98 -add video.264 sound.mp4
start /belownormal /b /w ATOMChanger.exe sound.mp4 MAQ10001.MP4 AtomAVC.ini

To do 2 pass encodes i tried adding this:
....x264.exe --progress --pass 2 --bitrate 312 etc

But it does not convert, do i have to add something else to this for two pass encodes?

my encodes are going at about 11 to 12 fps, is there anything i can do to speed things up?

get a faster computer

also, you could find you have seeking issues with those bframes and ref frames.

my p4 3.2 gives me around 23fps for second/third pass, this is my quot;slowquot; megui profile.

C:\Program Files\x264\x264.exe --pass 3 --bitrate 250 --stats quot;2pass.logquot; --level 1.3 --bframes 1 --b-rdo --bime --weightb --subme 6 --trellis 1 --analyse p8x8,b8x8,i4x4,p4x4 --me umh --progress --no-psnr --output quot;quot; quot;quot;

also, i had a problem (and someone else did as well) where using 2 threads would cause the video to crash the PSP even though it played just fine on the PC! if you wanted to rule it out, go to tools-settings in megui and untick  quot;automatically set number of threadsquot; then make sure only one thread is selected...

probably not the cause, but its something to rule out

You need to run the first pass with quot;--pass 1quot; so that x264 generates the stats file for the second pass.

My computer is quite recent from dell, and my old computer use to do encodes way faster and its like 4 years old, specs from new computer:

Encodes with x264 or some other codec? Comparing apples and oranges won't take you anywhere.

you should be glad you get those frame rates, on other settings you could go as low as 1fps

also, make sure you have the latest version from

take out all the stuff from the avs you dont need as this also slows things down

sorry mate i dont think iv been clear in what iv said,  on my old computer i did several x264 encodes using me gui, and got loads of good quality videos for my psp, encode times use to be a lot faster, but on this new computer which is a lot higher specd than my old one x264 encodes seem to be a lot slower.  

@ deets,  thanks for the help you gave before when i first got started off with this x264,  unfortunaly since i got this new computer i havent been able to get a playable video from me gui, iv had to use the bat file to get working videos. i will chec k to see if i have the latest x264

Then you (or MeGUI) just used lighter encoding settings previously. You'll gain speed (probably about 100%) by not using --b-rdo, --trellis 2. --mixed-refs and by using --subme 6 instead of --subme 7. The quality will be a bit lower, but you might not even notice the difference.

thanx mate i will test it without those

if your having the psp crash the video using megui please just try changing the settings to one thread and untick quot;automatically set number of threadsquot; in tools-settings.

i had this weird bug and one other user had the same. there is no reason why it should crash using sharktooths psp profile, or my profile.

try my profiles and see what speeds you get, slow gives me around 22fps per non turbo pass

i just checked me gui, and i have 1 thread already selected, and there is no check box next to it, i can only go up and down 9adding or taking away threads)?
one question though, im not too sure what the difference between ref. frames and b frames are.?
the only reason i changed to 1 ref and 1 b frame is because i had the seek/ jump to problem, i just wanted to know what they are?

im just trying to get the 2 pass encode run though the .bat file,  the first pass runs fine but the second doesnt start.

can sumone check my bat and tell me what i am missing please, thanks
:

start /belownormal /b /w x264.exe --progress --pass 1 --bitrate 312 --ref 1 --mixed-refs --bframes 1 --subme 6 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --direct auto --no-psnr --output stats.stats prog.avs

start /belownormal /b /w x264.exe --progress --pass 2 --bitrate 312 --stats quot;stats.statsquot; --ref 1 --mixed-refs --bframes 1 --subme 6 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --direct auto --no-psnr --output video.264 prog.avs

Try adding 2gt;amp;1 gt;pass2.txt to the end of the command line. That'll write its output to a file, so you can see the error message.

nm, I just noticed your apparent confusion about stats files. For the first pass, use --output nul, and for the second, keep prog.avs instead of stats.stats. (x264 generates a stats file name by itself if you don't feed it one.) And are you sure you want to go to raw video, instead of mp4 or mkv?

You are handling the stats file incorrectly. This should work better:

Code:
start /belownormal /b /w x264.exe --progress --pass 1 --bitrate 312 --ref 1 --mixed-refs --bframes 1 --subme 6 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --direct auto --no-psnr --stats stats.log --output video.264 prog.avs

start /belownormal /b /w x264.exe --progress --pass 2 --bitrate 312 --ref 1 --mixed-refs --bframes 1 --subme 6 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --direct auto --no-psnr --stats stats.log --output video.264 prog.avs
--stats is optional, and if it's not specified, x264_2pass.log will be used as a file name.

Better still for 1st pass (quot;turboquot;):

start /belownormal /b /w x264.exe --progress --pass 1 --bitrate 312 --ref 1 --mixed-refs --bframes 1 --subme 6 --weightb --analyse none --direct auto --no-psnr --output nul prog.avs

Also why are you using trellis 2 in second pass, but only --me dia? That's a bizarre prioritization. Try --me umh for nicely improved quality.
