PSP video encoding thread

[martTM]

Do any of you have a real world example of battery life?

Specifically, when playing back a movie off a memory stick, how does the battery hold up? Can you get through 2 movies or just one?

I watched the version of Hero I created with wonderboy's help the other day while on a long train journey - fully charged PSP at the start, which only went down to 74% after the movie finished an hour and fifty minutes later. Guess it's the same as music; because it's only reading off the card rather than having to spin a disc and power a laser, the battery doesn't suffer.

wonderboy, I need a suggestion from you though - I've got another fairly action-heavy movie called Casshern boiled down in the same way I did Hero (subtitles and all), but the final MP4 file is 537Mb... too big for my 512Mb card. I used the 2-pass method you put up many pages back when running through 3GP - 368x208/29.97fps/400kbps Stereo/128kbps - but do you have any suggestions of a different setting I should use to try and condense the original AVI file any further?

(Note: I strongly urge any fans of Asian movies to go to www.casshern.com and check out the trailer for this movie... it's like live-action anime and it's astoundingly gorgeous. )

Well, it seems I can encode small trailers and music videos fine using the 2 pass ini files of yours and dazza but when I put in a movie file say around 700MB, it comes with a error 128 at the end of the encoding and I don't end up with a mpg4 file at the end.

Any ideas wonderboy?

Anyone?

[zenza]

I am using this ini for my movies and although the video qaulity is excellent, full length movie comes in at about 640MB.

Is there anything I can do with the audio quality to get the file size down to fit on a 512Mb card?

The only thing I can suggest from experience is reduce the kbps - 768 is quite high. There's an ini. log back on page 26 or so that's got 2-pass AND a lower bitrate... got a 4.6GB movie of mine down to 400Mb, so that might help.

I can't see an ini log on page 26?

[martTM]

I did say 26 'or so'... it's actually on page 30. Not exactly far enough out for you not to find it...

Does anyone here use iPSP? I get an error at the end of the encoding, it creates a fuly working .3gp file but I get a "Quicktime Erro -37" in OS X.

Any clues?

[wonderboy]

Hi guys. Sorry i've been missing a bit. Anyway see if i can help...

zenza, as martTM said, i wouldn't use -b 768 it's about 250kbs/sec to
high. It's 1-pass, plus it's using -qmin 1. which is gonna result in the
output mp4, trying to match the input to closely. If you want to get any
video's down to a respectable size. You'll have to use 2-pass. With either
a set bit-rate, on the second pass. Or a min_max bit-rate to get the right
size (ie : -b ??? -maxrate ??? -minrate ???)...

One other, small thing people miss out on, is the sound. If you have a
really cool film, 2-ch at 64 is fine, but if the sound isn't that important.
Or having to 2 seperate channels of sound isn't gonna make much
difference. Or your only going to watch something, then maybe delete.
Use 1 channel 64 or 2 channel 32. Coming in at 950kbs/1mb a minute for minute. That 57mbs to 60 a hour. So, you'd save 30mbs an hour, if space
is tight, everything helps...

Also, i never had a 128 error, zenza, but if it's happening after the encode.
Did you check that when you copy and paste the info, into transcoding.ini.
That the lines aren't messed up. Check them, without word wrap on in
notepad...?

[wonderboy]

Hey dazzla. Sounds like the comformatity info, isn't being added or not
at all. So, when you open it in Quicktime you get an error. In windows,
not sure about the mac. You also, sometimes get the little + with the
drop down menu. If only either audio or video conforms. If neither
conform, then just an error....

I've been getting a lot of non-conformatity errors. Must have hand-made
loads of mp4 files. Testing what the PSP will play or not. It doesn't seem
to like b-frames. Yesterday i even tried mpeg4 AVC, just get incomatible
data...

Hi Guys,
We've been hard at work on PSP Video 9, a new freeware PSP video encoder/management application. We have come quite far in development and we are finally ready for a beta release. You can see screenshots and download it from our website:

http://www.pspvideo9.com

We'd love to hear what you think.
Feel free to leave any comments, questions or concerns about it in our forums or in this post.

[MonkeyWrench]

Weird, I came across your app on PSP Wiki and was going to post about it here

I will be checking it out later.

Anyway, for those that like to be old school a new version of 3GP has been released:

Thanks pspVideo9
one thing though. How differcult would it be to include a timeline? So you can control what thumbnail you generate for your movie clip.

[zenza]

Anyone used the new pspvideo9 encoder?

How does it compare to 3GP?

[AhMen]

I used psp9 and while i havent used 3gp or any other before i found it GREAT great video great. Keep up the good work

[plaver]

Does anyone have a grib sheet on how to use PSPVideo9, because I am finding the setup etc a little confusing,

I put in all the settings and file info in set-up area and when I then go to the convert tab the old setting are still there and I can't change them or am doing something wrong as usual.
