Full Resolution Video on the PSP

January 4, 2008

If you have a PSP with firmware 3.30 or later you can now (much more easily) play full screen h.264 video.

Prior to firmware 3.30 adding video to a PSP was a bit hit and miss.

Full Resolution Video on the PSP

When I first got a PSP I was very disappointed with the quality of the video I encoded for it using either EyeTV or Toast, more so when I compared it to the demo video I had on the demo UMD disk which came with it.

It wasn’t for some time that I didn’t realise that the PSP did not support full resolution video from a Memory Stick.

You also had to convert the video to a specific MP4 format and importantly change the name to something unfamiliar like M4V01011 and then find the obscure \MP_ROOT\100MNV01\ folder. You were restricted to a 368 x 208 resolution. If you wanted a thumbnail you had to create a jpg file and then rename it as .thm all quite complicated though there were quite a few tools that allowed you to do this quickly and easily (I used Toast quite a bit). One problem was working out what video files  were what (easy on the PSP, more complex on a computer).

With the release of firmware 3.30 this changed.

Encoding full resolution h.264 video for the PSP is now possible, this means that you can use the full 480 x 272 resolution and the excellent quality and compression of h.264.

However when I started to encode video for a PSP with firmware 3.30 I did initially have a few problems.

I tried to encode some full resolution video using VisualHub and the in-built settings and then some settings from a forum. However in both instances the video would not play on the PSP.

I initially thought it was maybe because at the time I was using the trial version of VisualHub (which has a two minute limit). However using the default low res settings it encoded and played fine.

I even formatted the Memory Stick wondering if that would solve it, it didn’t.

So I encoded the video in the original pre 3.30 firmware specificiations. As I copied over the video to the \MP_ROOT\100MNV01\ folder when I noticed a Video folder in the root of the Memory Stick.

So I copied the full resolution video over to this video folder, and guess what, yes full resolution h.264 video on my PSP.

Really impressed with the quality.

Really impressed with VisualHub.

So if you have firmware 3.30 or later ensure that you use the PSP to format the memory stick and then you will have a video folder into which you can copy the video files without having to worry about any naming conventions and be able to have full resolution high quality video.


Video on the VLE

August 22, 2007

I have over the years looked at how we can store and use digital video to support and enhance learning. Generally small video clips seem to work better online (just look at the success of YouTube) rather than whole programmes.

Though having said that I am currently enjoying the BBC Archive trial and the BBC iPlayer beta and on both of those I am watching full length programmes. However I am watching it for entertainment rather than educational – raises another question, is there a such a stark difference between entertainment and learning these days?

We are storing video clips we use on the VLE (we use Moodle) using the Flash Video format. Though some staff are using YouTube or TeacherTube.

Our Flash video generally streams “okay” both inside and outside the college.

I have found that using Quicktime H.264 encoded files results in a similar file size, but much better quality. This was particularly evident with the Italian Language programme I used as my example, where the audio was out of sync with the video when using Flash video which would have proved difficult for language students to follow the foreign language.

However it does require that the client have Quicktime installed and though this is a free download for users outside the college, the Quicktime player we have installed on college machines is not capable of playing H.264 content.

The main advantage of encoding H.264 was the time it took to encode the files. Though quality and final file size were also advantageous.

To encode a 15 minute MPEG2 Freeview recording took around 15 minutes on my iMac.

To encode the same 15 minute MPEG2 recording as a FLV file took about five to six hours… and then I needed to create a Flash object which contained the FLV video file.

We now have a 15 minute limit on files just because anything longer will take too long to download. For those video recordings/files we put them on DVD and allow the students to view them via a DVD player.

Longer term for larger videos we are aiming to have a media/video server, but this will be mainly aimed at streaming internally.
