Use full video resolution on 5th generation iPods iPod
With iTunes 7, Apple updated the iPod firmware to 1.2 for 5th generation iPods. Besides being able to use the games, the integrated Broadcom chipset for video is silently upgraded. The chipset always allowed resolutions up to 640x480 (H.264 and others), but Apple restricted that in the first versions. Now the power is fully usable (it's needed for Apple's new "near DVD-quality" movies from the Music Store.)

If you use the iPod as a playback VCR for your TV, you should re-encode all the movies you might have. Using QuickTime Player Pro 7.1.3, movies are exported for iPod now with H.264 in 640x480. The quality is stunning if you watch it full-size out of iTunes or on your TV (iPod connected with AV-cable). Other software soon might use the new features as well (iSquint, Podner, etc.).

Use full video resolution on 5th generation iPods
Authored by: chrisjniles on Sep 19, '06 12:48:51PM

I have a question about the increased resolution. If my memory serves, it was possible to play videos at any resolution that added up to 230400 (multiples of 480*480) pixels. Is this still possible with the new video codec for the 5 gen iPod?

I guess what I'm asking is if you can encode video at a different resolution as long as it adds up to 640*480 (307200) pixels. I think this would be great for playing wide aspect ratio videos (16*9 videos vs. 4*3 videos) on your higher definition TV, as you could have more horizontal pixels than 640.

It might not be much of a difference, but I was just curious.

Not trying to be a troll or anything (i know this is a little off topic), but "stunning"? In my mind the 1080i trailers from apple.com/trailers are stunning! Normal DVD is average, the apple videos are barely 'acceptable'.

Give me 1080i no DRM H.264 videos for $19.99, 720p for $12.99, DVD for $9.99 and smaller for no more than $4.99.

Now THAT would sell.

ok i think your crazy.

just think about that for a minute, it takes me almost equally as long to download a trailer at 1080i as it does to download a movie from itunes. the sheer bandwidth needed by apple to support 1080i MOVIES would be phenominal and it would still take forever on an average connection speed

Oh, yeah, well...I have FIOS =) 15Mbit/2Mbit

The 1080 trailers tend to be about 8000kbit or half my connection so I can watch them in real time. I wish apple would optimize quicktimes downloading engine, since I can barely watch in realtime while its downloading (cpu's get maxxed) but once its done downloading it only takes up like 60-70% iirc. I usually use 720p just cause my computer isn't fast enough.

I was mostly just complaining that 640x480 is hardly 'stunning' even DVD's area little disappointing compared to HD these days.

VisualHub 1.1.3 does 640x480 H.264
Authored by: TylerL on Sep 19, '06 03:37:34PM
VisualHub was updated today to convert 640x480 H.264 for the 5G iPods.
Choose your own image size, bitrate, etc. Even two-pass encoding.

iSquint support coming later. I need to dive back into the code and update a bunch of stuff there first...

Thanks for the info! Oh, thought I should mention that the Apple Trailers are in 1080p, not 1080i. Stupid little correction...

Am converting my pre-converted files (512x400 MPEG4) all over again since my converter (PQ DVD to iPod Video Suite) released its support for 640x480 H.264. Looks better than the 512x400 in my HDTV.

1080i vs 480p (what they have now) would not be that hard. It's that little i that makes all the difference. Since 1080i is interlaced we're able to throw out 1/2 of the data while encoding which means from a bitrate standpoint it would be closer to 540p, just a wee bit more than what they use for 480p. If Apple went with 720p or 1080p then yeah, we would have an issue... But since 1080i is on the low end of the HD spectrum (higher number doth not higher quality it make) it should be fairly easy for Apple to introduce.

Since I'm an HD purist, I would like to se interlaced content die. Since most users screens are progressive anyhow (LCD, DLP, Plasma) it seems silly to keep interlacing the content. I would love to see 1080p videos online, but it's a difficult balance.

Just my $0.02.
