iPod my ipod plays video at 720x400

That's probably the reason but what I'm interested in is the settings you used. Did you encode with MPEG-4 or H.264? What bit rate? Do they look good?
I'm so jonesing for a new 5.5G iPod to replace my 3G - it's really starting to cough and splutter.

So you're using HandBrake? I've been trying to rip my Season 1 of Lost for the last year, and Season 2 for about a couple of weeks. But HandBrake doesn't allow them to be opended. It scans the titles and then nothing! What region is your drive? and what region are the Lost DVDs?

Well, I did not rip them at the miraculous settings the OP is suggesting (which I would love to try out, BTW
) but I did rip all of the first season of Lost and transferred it onto my iPod right last night.My drive is region 2 as are my Lost DVDs.
Handbreak scanned them and ripped them as usual.
The only problem I had was with the first disc where it ripped the two parts of the pilot twice, instead of ripping episode 3 and 4.
I am gonna try and re-rip the first disc when I am back from work.
All other discs worked flawlessly.
640x480 represents the max number of total pixels, as NicP pointed out. This is true for both MPEG-4 as well as Low-Complexity Baseline H.264. I routinely put videos at their native resolution on my 80GB iPod. I use Handbrake with the following settings:
- Framerate: Same as source
- Encoder: FFmpeg
- Quality: Average bitrate: 2200 kbps
- 2-pass encoding
- File format: MP4 file
- Codecs: MPEG-4 Video / AAC Audio
- Audio settings all at default
- Picture settings at native settings: 640 wide for "full frame" video, 720 wide for widescreen video, aspect ratio fixed. Choose "deinterlace" if preview screens show lots of horizontal lines.
Simple and effective with very good results. I wonder if H.264 will give me better results at 1500 kbps than I get using MPEG-4 at 2200 kbps?

Chundles, my 4G coughed and spluttered much, so I replaced it with an 80GB iPod. Very happy with the video output and overall capabilities. Would be nice if the screen were larger (even at the same pixel count), but oh well.

amin can I ask you how many MB/GB do those files end up being? I would love to rip at the settings you suggest but I am a little worried about how many files I could fit onto my 30GB iPod, considering I've got 15+GB of music and pix.
Thanks
You guys have it wrong. It's NOT just the amount of pixels that matter but the macroblocks.
MPEG-4 is limited to a maximum of 900 16x16 macroblocks. It works this way:
720x400 (which is 16:9): 720/16=45 x 400/16=25 45x25=1125. Also the pixel count is over 230400
So in short, Handbrake does not support Baseline Low-Complexity profile so you can't make a H.264 of that size to work on your iPod and the MPEG-4 file won't play on your iPod either as it exceeds both the pixel and macroblock count.
The new H.264 has a macroblock limit of 1200 so theoretically the iPod should play 720x400 H.264 files. I have yet to 100% confirm this.

I had to try it for myself. It does work indeed. So everything I said previously is not true anymore... Embarrasing really
So it definately seems the the new firmware upgraded all the formats as you said. I wonder what the current macroblock limit is...
UPDATE: From Apple's website: MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per sec., Simple Profile with AAC-LC audio up to 160 Kbps, 48 kHz, stereo audio in .m4v, .mp4, and .mov file formats
That means a total a maximum pixel count of 307200 but more importantly maximum macroblock count of 1200 (640/16x480/16).

Why not use the target size feature in Handbrake? It'll calculate the average bitrate needed to fit movie/video in the desired size.
MacinJosh said:
Won't work because as you said, Handbrake currently can't do Baseline LC. The only H.264 content you can get at the moment is either 640xwhatever from the iTunes Store or the older 320x240 stuff ripped in Handbrake. It's highly possible it will work but until Handbrake gets Baseline LC as an option nobody will be able to test.
from the developer forums at handbrake's site it looks like they are getting close, but there are still no public builds. the latest source will work supposedly if you download and build it yourself.
MacinJosh said:
Oh thanks, I didn't know handbreak had that feature.
I'm away from my Mac but I'll try this tonight.
Chundles said:
ffmpegx and VisualHub (I own both) do Baseline LC but neither produce a valid 720x400.
The weird thing here is that I was absolutely sure that I succesfully tested a 720x400 H.264 file on my iPod. I had exported a 720x400 resolution movie clip in QT to iPod and it had kept the resolution intact at said resolution.
Now, however, I can't succesfully replicate the test. QT automatically changes the resolution to 640x*. So it's either:
1: I was on drugs (not possible) or was experiencing temporary insanity during the testing.
2: Something has changed (updates, whatever) on my computer so I can't do it anymore.
That's why I'd like to know if anyone else here has done it.
Joshua.
So what would be maximum height available with 720 wide? 400?
And if someone successfully created a 720xWhatever movie that played on iPod, could you please share the specific software and settings you used? I've stopped ripping my DVD collection since the new bigger format appeared - I don't have any software that rips dvd to it.

yeah. the forums say the build is pretty unstable at this point but it does work. i posted it in the main encoding thread here. it appears the actual codec apple is using (the supposed Baseline LC) is actually the same as the normal Baseline. the only difference is apple seems to be doing what is in effect an internal watermark into its iPod converted files from Quicktime/iTunes. if these little bits of data are not present it will not transfer/play onto an iPod. what the latest builds do is it injects this bit of code into the handbrake outputted files.
so any H.264 file over 320x240 must have this data or it won't work.
