Hey Zelig

Thanks for that. Probably a dumb question but the way I am saving and then importing it (your settings) doesn't seem to work. Errors when I try and import. Could you maybe explain how to do that? I also tried petes by manually going through and setting things and that does a nice job. Thank you.

I don't know how you import that XML user preset I posted previously - I have now deleted it to save further confusion.

To get my settings, just follow these steps:-

1. Open HandBrake.

2. Select SOURCE Video_TS folder

3. Select iPhone & iPod Touch preset from the Presets on the right.

4. TICK "Keep Aspect Ratio"

5. Change Width to 640 (Handbrake should then change Height to 368 or 352 depending on source - assuming source is 1.78 Aspect Ratio)

6. Click Start


Let me know how it goes.

You can also reduce the Constant Quality setting if you want to reduce the file size...... my eyes can't discern any difference in quality on the N900 screen.

You would have replace the user-preset.xml on the client machine with yours.

Or, they need to copy/paste your xml set into their user-preset.xml into the right place.

Not the easiest way to share a preset.

Indeed - hence why I deleted it.

As the steps above show, it really is just a minor variation on the iPhone/iPod preset.

Easiest way to make the preset is start with iPhone preset, make the changes, then save it as a new preset.

Jaffa, why are you so defensive? By 'your' page and 'mine' I;m merely using shorthand for 'the page you created and maintain' etc. I feel no sense of ownership over it! If you don't like it, by all mean delete it. I made it because I thought it would be useful. If it's not, remove it. But in a week or two you will have people in here again needing a basic walk-through, who don't care to know about codecs and settings. They just want to put their dvds on their n900.

To the people saying the .plist imports don't work - can you please check? Cos I used both of them and they worked fine for me. But, I was using the 'high quality' one on a relatively modern DVD and got a file out that was 'widescreen'. I only used the other one on old-fashioned 'square TV' programmes, (and got square output) so if they don't work in widescreen I wouldn't know. I did notice the instruction not to use anamorphic, and that the presets did - but it worked for me.

If someone would like to improve on the presets, by all means do. I think two qualities is probably valuable though - a basic and a seriously HQ.

If you don't think that a second page is the answer, incorporate a basic guide into the more complex information. Personally, I think a 'dummies' guide is more useful without all the extra information. It's less confusing.

I said there's no "your" page or "my" page for two reasons:
  1. It's a community-owned wiki, so no-one really owns any of the content once it's uploaded.
  2. I didn't write the earlier Video encoding page :-)

But in a week or two you will have people in here again needing a basic walk-through, who don't care to know about codecs and settings. They just want to put their dvds on their n900.
I agree! I want the codecs & settings stuff to be buried - I want the stuff to be easy to use. That's why I was suggesting merging all these "easy to use" guides! I hate remembering esoteric command lines, complex options and running around with resolution/bitrate settings in my head. That's why I wrote tablet-encode, which was the first preset-based media transcoder targetting Maemo, and the first encoder anywhere (AFAICT) which had Maemo device presets.

If you don't think that a second page is the answer, incorporate a basic guide into the more complex information. Personally, I think a 'dummies' guide is more useful without all the extra information. It's less confusing.
Again, I agree entirely. And all the complex information can now be summarised as a simple table of device, maximum audio bitrate, maximum video bitrate, maximum bitrate and maximum framerate. Anyone who wants to re-engineer their own encoding solution can look at the Handbrake presets, tablet-encode's presets etc.

Do you (or anyone) know what the maximum video bitrate is for the N900 ?

I will - am actually using your settings right now to check! For reference, I am getting ~ 800MB for most, but sometimes crazy things are happening and e.g., Akira comes out as 1.7GB.

When I put in 640 (the DVD storage width), it drops the height to 272. To stop the Media Player having to rescale, I was leaving it at 720 in width; this was because I had so much trouble initially with slow H264 playback my primary concern was getting smooth playback, regardless of filesize.

Part of what I was doing was having MP4s that would play also in my PS3 so I didn't have to keep two parallel encodes.


NB: I don't tick Web Optimized because I am only using the internal memory of the N900,
I couldn't get the MP4s to playback at all unless it was ticked.

My own experience says that 800x480, 2000kbps video and 192kbps audio are sensible maximums. They aren't the absolute maximum, but you can't reliably push past on all types of video.

Well.. for what it's worth..

It's IMHO that there should be 2 wiki's. The most basic simple guide like what kathy put together. This should have basic setup instructions for a couple different software for the different OS's (linux, mac, windows) and downloadable importable presets for all that software.

NO codec information, NO bitrates, NO container information.

"Install XYZ, Load this, Hit Rip, Profit."

Then another page more like the Video_Guide we have that lists out the different pages of different software, the different settings, different bitrates.. yadda yadda etc.. for more advanced tuning for those that want to do that.

I do not see any way to merge these two into one wiki document and not scare off the video encoding n00bies out there.

Just MHO.
