Converting MP4 video for the PSP (h264/AVC) on Linux
After my earlier post about converting video for the PSP proved to be pretty popular, I decided to do a new, easier, better and improved guide. Well, here it is, as promised. It took me a while because I had a lot of other things on my head the last few months. Well, better late then never, so they say. This time we're going to do MPEG-4 AVC (aka H.264) instead of plain old MPEG-4 ASP I used in the last post. A lot of things have happened since I wrote that other guide more than a year ago. First of all, I've learned a lot more about the PSP's compression techniques, mostly thanks to Robert Swain's great blog. Secondly, newer firmwares released by Sony have loosened up the restrictions for Video on the PSP. So first I'll show you a updated list of the restrictions for video on the PSP in AVC (AFAIK):

Well done! This works perfectly.
Thank you for taking the time to go through all of this for those of us too lazy to do it ourselves. You saved my arse tonight. :)
You're welcome. ;-)
I use Kubuntu 7.10 and this works perfectly. It's really made my day.
I followed these instructions. Then I copied the file to MP_ROOT/100MNV01. I renamed the file M4V23456.MP4. It shows up under video, but says unsupported. I started with an xvid/mp3/avi file. What am I doing wrong? Thanks.
You should just copy it to the VIDEO folder in the root of your memory stick. No need to rename it to M4V?????.MP4, that was only necessary with older firmwares.
this is fantastic, i was about to abandon linux after a couple of years for the lack of a psp click and go solution...
now somebody needs to port itunes and i can forget about win forever...
thank you !
Port iTunes? Did you have a look at what Rhythmbox has to offer? And then there's also Songbird, Banshee...
This is without a doubt, the best psp video conversion walkthrough like....evers. I tried it and got perfect files everytime. Thanks so much!
I can never get videos to convert for PSP on Linux. I followed this guide, and avidemux would just crash. When I simply use the PSP preset without all of your extra settings, it makes a video which I can play on my computer, but shows up as "Unsupported data" on my PSP. What could I be missing?
What Linux distro and version of Avidemux are you using?
Dude... very nice! Thank you.
I'm using the OS X port of Avidemux, interface doesn't look as flashy as ubuntu but from my small tests so far the output looks great, seems fast and is exactly what I was looking for.. was earlier trying a program called handbrake but couldn't get it to output for PSP at 720x480... it also uses ffmpeg... do you happen to know what the command line trick is for 720x480? I can get 480x272 no problems, is it something to do with the baseline option? i've tried level=13 (1.3) and level=21 (2.1) also tampered with 30 (3.0), no joy so far.
Am thinking about converting my fave movies to 720x480 so i can use them on psp and ps3... however I guess you lose the anamorphic squeeze as the PSP won't unsqueeze that at 720x480 or?
Just answered my own question there and sorted out handbrake! :) Thanks again..
for 720 x 480 it has to be AVC h264 Baseline level 3 or higher, but 3.0 does the trick. (ie. in handbrake "level=30" in the bottom of the advanced tab.)
See here for why http://en.wikipedia.org/wiki/H.264#Levels
Anyway, I still think Avidemux did a neater job somehow and faster... so will continue using both.
Indeed, for 720x480 you need to use level 3.0 (which afaik is the maximum level the PSP can handle).
Anyway, it's always best to stick to 3.0, because I think it allows for some extra compression tweaks in the codec to further reduce the filesize/increase quality.
Great guide! 1,000,000 thanks!
A side note: It seems that avidemux (my version at least) defaults to the .avi file extension. PSP appears to barf with this extension, telling you it's corrupted data. All you have to do to fix this is rename the file extension to a .mp4. (This took me 2 hours to figure out!)
Thanks so much for this. Works like a charm, and now my daughter has a full Memory Stick of Dora the Explorer for tomorrow's flight.
You're the Light in the dark night :)
Thanks a lot!!!
You're welcome... ;-)
there is no mention or apparent ability to boost the audio...is the typical audio file already proving to be satisfactory in most instances (where so many other apps are not) ??
Hey, nice guide!
It helped my convert two movies that I really wanted to watch on the go :D
The problem is, the audio starts to trail off in each movie, and I looked around the web, and I still can't find the solution to my problem D:
Can you help me?
Congratulations on your guide. Very very helpfull..
I just bought a TV-OUT cable for my psp slim, and i was searching everywhere for some way to convert movies to watch on tv with good resolution...
But i dont know if this can de done faster... it tooks me like 7-8 hours to encode one movie in 720x480 resolution...
The original was an avi file of 700MB with 6xx X 3xx resolution..
What i have to do to make the conversion faster? I got an asus f9s, with core 2 duo 2.0 (T7300), 4gb ram, and geforce 8400M G
"there is no mention or apparent ability to boost the audio...is the typical audio file already proving to be satisfactory in most instances (where so many other apps are not) ??"
Well in most cases the videos volume should be high enough. If it isn't then you should just check out the audio filters in Avidemux, you can increase the gain there.
"The problem is, the audio starts to trail off in each movie, and I looked around the web, and I still can't find the solution to my problem D:"
This could be a frame rate issue, check if the output frame rate is the same as the source movie. Also converting from certain codecs will give you trouble at times. (wmv is notorious for this) Sometimes the sync is of from the start and you can fix it by setting the time shift in the audio filters.
"But i dont know if this can de done faster... it tooks me like 7-8 hours to encode one movie in 720x480 resolution..."
Well there's very little you can do about that I'm afraid. Converting a movie to h264/AVC at the highest quality at that resolution just takes a lot of time. (On my Pentium 4 I need to let Avidemux work the whole night for a 480x272 movie.)
If speed is really important to you, you could just reduce some quality settings so it encodes faster. (Experiment with the options in the Motion & Misc and Partitions & Frames tabs. Try reducing Partition decision and Motion Estimation Method.) But then obviously you'll lose video quality.
The only solution to encode faster without giving up on video quality or bitrate is to buy a better CPU (or two). ;-)
about the speed... and if i just want to rum exactly the same avi in the psp?
i mean... a mp4 with same resolution and audio im mp3, like the original... can this be done? will it be faster?
can psp play the original avi without converting it? =P
That would work only if the video codec is plain mp4... (So if it's DivX or XviD it won't work.)
Either way you'd have to convert the audio to AAC. You can try following this tutorial, but before saving just setting the Video Codec to "Copy". Though there is very little chance it will play on the PSP.
Another option is converting the video to MP4 ASP. (It's the other option from the Auto Wizard.) In that case you don't have to bother about the advances encoding preferences, they should be okay by default.
Your video will look a lot uglier though (or be a lot bigger, depending on the bitrate)...
The cool thing about h264/AVC is that, at the maximum settings, you can cram a whole movie into a 400MB file without losing a lot of quality.
First off I thought the guide was very informative and helpful. Although for me it didn't make it the whole way.
I had first been tinkering around in Avidemux on windows vista by myself. But, not being all that informed about all aspects of video I did fall short. First when I was trying to convert videos avidemux would crash when trying PSP h264.
With your guide the video would atleast successfully convert the file. And here is where the problem lies. Like a poster above I got "unsopprted data". I had as well renamed my file m4vXXXXX.mp4. Then I read your note about not having to rename files in that manner anymore, so I named it back. My PSP 3000 has firmware 4.20, and when the file wasn't named m4v*.mp4 then the file wouldn't show up at all when going into the vide section.
I am using Vista, not linux.
Avidemux version 2.4.4
and firmware 4.20 on my PSP.
I would be very grateful to any insight or better yet a solution to my problem.
What folder on your PSP are you placing the video in? You should place it in a folder called VIDEO on the root of your PSP, _not_ in the MP_ROOT folder. (That's only for firmwares older than 2.80.)
Is the folder I place the videos in.
Like you said, creating a video folder in the root and placing it there under any name worked perfectly.
Thank you very much. :)
Hi, it's me again, the guy who asked if the conversion could be faster... Just to you add to your tutorial, 640x480 is also a supported resolution =). i tested it! cya, and thanks!
Avidemux 2.5.0 is released!
Some standard settings are changed for the PSP (two pass, uneven multi, average bitrate: 1000)
*pushed my chair away from desk.Stand applauding*
Anyone can get it to work. You gave explanation on how to get it to work AND look good AND to customize. Well Done.....!
Thank you so much for this excellent and detailed tutorial. It's exactly what I've looking for.

"configure the encoder for super-mega-uber-optimized encoding". You must be joking! You didn't even enabled 8x8 DCT Transform or Mixed References !!!
That's because the PSP doesn't support 8x8 DCT Transform or Mixed References. (Or at least didn't at the time of writing this guide.)
Video produced using AviDemux v2.5.2's PSP auto config does not work (on the PSP). Turning off 8x8 transform and changing max ref from 3 to 2 gets it working. Was able to work this out thanks to your excellent post. Thank you.
When using Avidemux 2.5.3 you need to install the following patch
That will provide the correct profile with all the fixes mentioned above + more.
Thanks a lot for posting this guide. It worked well for me. I'm using Ubuntu 10.04, Avidemux 2.5.2 and PSP 3000. Right now I'm converting a whole movie plus subtitles. Thanks a lot again dude! :)
Sorry, but this specs are awfully wrong. you can go all the way up to 16 b-frames, 3 reframes (which makes A LOT of difference!) and use more different resolutions than named (368x272 for example).
I know it because I've coded a bunch of movies for PSP and did a research before. doom9 helps a lot.
