PSP owners, which settings do you use for different kinds of content?

[Chainmax]

I'll be receiving a PSP within he next two weeks and was wondering how do you encode different contents (live action, animated, 4:3, 16:9, low motion, high motion) for your PSP, i.e: what resolution, what bitrate, which x264 options, etc.

Check out this thread (http://forum.doom9.org/showthread.php?t=127611)

MPEG-4 AVC might not have been the first place to ask :)

[Atak_Snajpera]

If you want very high quality for 480x272 use CQ at 24 (~768 kbps)
but if you want to save space on memory stick with at least good quality I suggest 2-pass at 384 kbps for movies and 256 for anime.

[Chainmax]

I see thanks :). Would 384x288 video encoded with CQ24 play back smoothly?


[edit]Also, I normally process audio and video separately. Having an x264 MP4 and an MP3/AAC soundtrack, can I simply use YAMB and mux those into a single MP4 or do I need a special muxer?

[Sagekilla]

No, you don't need any "special muxer," YAMB should work quite fine. I used YAMB to mux some videos for my PS3 and PSP and it worked well.

[Atak_Snajpera]

I see thanks . Would 384x288 video encoded with CQ24 play back smoothly?

PSP is able to play even 720x480. So I see no problem with lower resolution.

[Chainmax]

Sagekilla: that's good to know, thanks :).

Atak_Snajpera: isn't 720x480 only for ASP encodes?

[Atak_Snajpera]

PSP is very powerfull. It can decode 720x480 AVC @ 4mbps without any problems :)

[Wishbringer]

I use 720x480 at crf 18 and it plays smooth. Ok, it's quality overkill for PSP, but so i can use same files for PS3 too.

[Chainmax]

On second thought, that doesn't make much sense: if the PSP can decode 480p AVC @ 4Mbps using MeGUI's PSP profile, why couldn't it handle 272p AVC using the AE-Maxquality profile?

[Dark Shikari]

On second thought, that doesn't make much sense: if the PSP can decode 480p AVC @ 4Mbps using MeGUI's PSP profile, why couldn't it handle 272p AVC using the AE-Maxquality profile?Perhaps it can't handle High Profile?

[Atak_Snajpera]

Exactly! PSP supports only main profile!

[Lancerevo]

I use Xvid4PSP to encode the videos to .pmp 480x272 2pass 64kbps AAC with a 100MB filesize limit for my animes. Other smaller vids I'll just round them up to the nearest number.

[Atak_Snajpera]

To play .pmp files you need custom firmware. I doubt that Chainmax has anybody with pandora battery (flashed battery) .

[Chainmax]

Too bad it only supports Main Profile. At least higher bitrates can be used to overcome that :).

By the way, Atak_Snajpera, the PSP I bought is used and has the 1.5 firmware on it, so updating to latest CFW shouldn't need the Pandora trick. As for .pmp files, who asked about that and waht are they?

[Atak_Snajpera]

Too bad it only supports Main Profile.
PSP LCD has terrible latency (ugly ghosting effect) and Believe me Main Profile is enough :) High Profile = 8x8iDCT and that's it.

[Chainmax]

I encoded four small videos: three at 384x288 and one at 480x272. On firmware 3.40 OE (going to update to latest M33 one soon) only the 480x272 one plays, and mute at that. What could be causing this?

As for .pmp files, who asked about that and waht are they?PMP is an alternative container for PSP that can contain ASP and AVC video. I recommend PMPlayer Advance for playing. But MP4 can have higher quality right now. PMP has some features like bookmarks.

[rootkit]

I have a script that encodes for teh PSP: http://teknoraver.campuslife.it/software/mp4tools/

here is a sample: http://teknoraver.campuslife.it/software/mp4tools/psp.mp4

You have to use latest firmware tought

[Ranguvar]

My typical 2-pass VBR encode:

--pass 1 --stats .stats --bitrate 768 --sar 353:375 -A all --aud --level 3.0 --ref 2 --mixed-refs --bframes 3 --direct auto --analyse none --me dia --subme 1 --threads 1

--pass 2 --stats .stats --bitrate 768 --sar 353:375 -A all --aud --level 3.0 --ref 2 --mixed-refs --bframes 3 --direct auto --analyse all --subme 6 --me umh --b-rdo --bime --weightb --trellis 1 --threads 1

[Chainmax]

rootkit: I usually filter my sources and like to specify the parameters to be used during encoding, but thanks for the links anyway :).

Ranguvar: I chose 384x288 because it's the MOD16 4:3 resolution with the closest height to 272. Do you know where can I find a list of supported resolutions so I don't run into this issue for other ARs (2.35:1, 1.85:1, etc)? Also, the audio on the 480x272 clip (the one that played but without sound) was standard youtube-type fair, 64Kbps mono @44.1Khz, is that not supported either?

[Chainmax]

Atak_Snajpera, Ranguvar: can either of you please answer the questions in my previous post?

[Atak_Snajpera]

As long as you don't exceed 480 vertical lines and 272 horizontal lines everything is ok. I just made few encodes 480x204 , 360x272 , 360x270 and all work.

Only stereo is supported by PSP

[Chainmax]

You mean not exceeding 480 horizontal and 272 vertical, right? If so, then how were you and Wishbringer able to test 720x480 videos? Besides, when I asked about 384x288 you said there shouldn't be any problems :confused:.


I'll try upsampling the audio to stereo, see how does the 480x272 video play and report back.

If resolution =<480x272 you can use any resolution(480x204 , 360x272...) . Above that only 720x480 is supported. 640x480 , 512x384 ,400x300 and so on don't work. Sorry about 384x288 :) I made mistake...

[Mtz]

As of firmware update version 3.30, H.264/MPEG-4 AVC Main Profile video files of the following sizes can be played: 720×480, 352×480, and 480×272.

I'm wondering why is 352x480 and not 480x352?

I doesn't matter because both resolution are useless.

352x480 is an NTSC SVCD/DVD resolution, it's obviously anamorphic. It's so stretched out that it looks like VHS, really. (Which is why it exists, to cheaply hold lousy low-detail VHS transfers.)

[Chainmax]

Are available resolutions only dictated by firmware or could a third party player bypass that?

[Chainmax]

I also forgot to ask: other than MP3, can audio in a clip be AC3, Ogg or AAC (HE/LC/SBR)?

[Atak_Snajpera]

Only AAC-LC is supported.

[quake74]

I have two files encoded using avidemux (if that makes a difference) but one plays on my psp and the other one does not http://rapidshare.com/files/73311883/psp.zip.html Can you tell me why? Did I miss anything stupid?

Edit: Crap, sorry about that. One has 2 audio channels (and it works) the other 6 (and it doesn't work). Nothing to see here, proceed to your normal activities...

I recently muxed a mono AAC file to a video and the sound played back fine.

[Atak_Snajpera]

With old firmware only stereo was supported.
