With such improved bitrate, maybe it would now be worthy to support 640 width limited anamorphic encoding for the iPods.H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; H.264 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Baseline Profile up to Level 3.0 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats

Improved bitrate supported on new iPods
It seems Apple has improved the h.264 support on the new iPods:
I noticed that little-advertised upgrade. Hopefully there's a retroactive upgrade for old iPods. In any case, it should be a simple addition to Handbrake as the LC 3.0 was the original 320x240 spec for iPod video encoding. If this will do widescreen video at greater than 640 width, there will be no more reason to use MP4 on the iPod.

So, and sorry for being a neub, but what is the very best setting I can use now?
Can I select iPod Hi - Res and kick the bit rate up to 2,500? Or does this mean I can pick the Apple TV setting?
I'd love to have the best quality I can for the new iPods and the Apple TV's. I also have an iPhone, but I understand the iPhones have very limited video output, so that is less of a worry. (Unless I am wrong about this.)
Thanks so much in advance.

Initial indications are that [higher bitrates] may be possible, but with some pretty big caveats - simply encoding to 2500 without setting some other stuff correctly will result in a movie that skips and jumps a fair amount.

Btw, it appears that this improved bitrate works on the 5th Gen Video. I think iTunes 7.4 simply removed a software limitation of the bitrate. I used Handbrake to rip one chapter from Kill Bill Vol. 1 (ch 6), by using the Hi Rez iPod setting, and simply changing the bit rate for the video from 1500 to 2500. Verified the bitrate in iTunes, tried to sync with the 5th Gen ipod... all was fine. Plays fine too.

Yep, 5 G ipod will play 2500 kbps abr video in x264, I strongly recommend adding vbv buffering though to keep bitrate spikes down so you are less likely to lose frames during complex scenes.
I am using this advanced opt string for testing with good results:
Note: Once again, remember that x264 does not observe any vbv buffering in two pass mode, so the buffering will only work using single pass.

Code: Select all
keyint=300:keyint-min=30:bframes=0:cabac=0:ref=1:vbv-maxrate=2500:vbv-bufsize=2000:analyse=all:me=umh:subq=6:no-fast-pskip=1

Yes but... does it play with any finesse! Can you watch the thing ON the iPod screen or does it look like a bad animated .gif!pizzaspecial wrote:Yes i have tested those settings on an ipod classic and so far 3 dvds have worked perfectly
I actually select the high rez preset in handbrake up the kbps to 2500 and change the resolution to 720x400
Plays on an ipod classic perfectly
Transfered using itunes too
I have never had a problem with the small screen, but the mottled greenish faces, banded gradients etc. on some videos, especially sci-fi don't inspire me to buy another iPod that's no better.

I don't know if this info will be useful, but the apple store's page for their new video cables lists slightly different specs:
Note: Component video output to television is supported by iPod nano (third generation) and iPod classic at 480p or 576p resolution, and by iPod touch at 480i or 576i resolution.
http://store.apple.com/1-800-MY-APPLE/W ... =MB128LL/A
Maybe worth trying some different settings for the new ipods based on this?

The video quality on the iPod classic screen is very good so is the output to a 720p 42inch Plasmavoxsola wrote:Yes but... does it play with any finesse!

Hello,
Big news with the new iPhone and Handbrake... I was able to get high resolutions (full resolutions not 640 width) with very high bitrates way above 2.5 mbps to work with the iPhone.
Very amazing I must say... I was loading these up via iTunes.
I have tested small clips with Bitrates at 3.0, 4.0 and 5.0 mbps.
Looks like these iPods are the TRUE VIDEO ipods.
I will post if any problems happen... so far though all is working well..
REMEMBER these are small clips so test away I think you will be surpised by what you can put on these new iPods/iPhones.
ENJOY
