No MPEG-4 support on new iPod Touch?
I've had a 1st Gen 32GB iPod Touch for a year or so, which I primarily use as a video player; all my video I convert to MPEG 4 format, which worked very well.
I've just bought the new 64GB 3rd Gen iPod Touch, loaded some of my video onto it, and discovered that when it plays, all I get is a solid green background. A little experimentation shows that if I recode the video to use the "H.264" codec rather than MPEG4 it plays fine. Has Apple actually documented the fact that MPEG4 is no longer supported on the new devices? It's a bit of a nuisance! |

I did check and listed amongst the various supported video codecs on the Apple Tech Specs for the new Touch is:

Second, until we know if this is a hardware issue or a function of the new OS (3.1.1), I am now officially hesitant about updating the software. Can anyone who has updated to 3.1.1 on a Touch verify if this is an issue on older iTouch hardware? I setup my video conversions some time ago, and I don't even remember what specs I am using. I'll have to go back and look. The Bandit |

Thanks for that. There's obviously SOMETHING about my video that the new Touch doesn't like, in that case. The same file plays fine on my original Touch (with v3.0 firmware), fine on my iPod "classic", but doesn't work on the new Touch (audio is fine, video is just solid green).
Perhaps it's just the particular settings I used when encoding it. As I say, if I recode it for H.264, everything's fine. Unfortunately that's a slow process! |

I think this happened to me before, a video that had been fine suddenly became all green. I deleted it from iTunes and imported it again, and it worked. I guess the file had become corrupted somehow.

GntlmnBndt - I have an iPod Touch V2 which I recently updated to 3.1.1 and I can still
play videos in MPEG-4 format which I downloaded from The Internet Archive with no problem. |

Unfortunately it's all my videos, not just one, so it's definitely some incompatibility between whatever video settings I used, and the new Touch.

It does seem a bit strange, maybe the new one is a bit pickier on what kinds of mpeg4s it plays.
I had a quick look at http://discussions.apple.com/categor...categoryID=221 and I couldn't see any references to the problem you are having so it might be an obscure bug. Have you tried using different bitrates/framerates and resolutions. It might be less tolerant. |

As I say, if I recode my videos for the H.264 codec rather than MPEG4, it works, so I do have a solution. It's just annoying that I have to do this for hundreds of hours of video!

Sorry, but you do realise that h.264 IS mpeg4 right?
http://en.wikipedia.org/wiki/MPEG-4#MPEG-4_parts (look at part 10) http://en.wikipedia.org/wiki/H.264 Further more, could you post some (or parts) of video's that do and do not work? I have an iPhone 3G, and a friend of mine has a 32gig touch, sure we could test a bit for you. |

A lot of people try to bring over .avi (which is usually xvid or divx ) which is not supported by iTunes, even if it has an .MP4 extension. If you're videos are sourced from the sharing sites they're most likely to be <720x pixels wide, Xvid with either MP3 or AC3 audio and the .avi extension. These will never work with an itouch without re-encoding. You can find out exactly what kind of file you have by running it through the excellent Mediainfo, which can be downloaded from Videohelp.com http://www.videohelp.com/tools/MediaInfo Run one of your troublesome files through that and we'll soon get to the bottom of the problem |

Thanks, when I get home from work this afternoon I'll do that for one which works, and one which doesn't, so that we can see what the difference is.
No videos from file sharing sites; they're all converted from DVD (bought bought ones and recorded from TV), converted using a program called "Aimersoft DVD to iPod Converter". |

I use Handbrake http://handbrake.fr/downloads.php, a free, open source DVD/File to MP4 creator. It does an excellent job, and has the best pre-set templates for iPods and other devices that I've seen. I rip my DVD's with DVDFab HD Decrypter (free version) http://www.dvdfab.com/free.htm |

Here's what iTunes has to say about a file that doesn't play on the 3G Touch, and one that does. Both files play perfectly in iTunes, and the one that doesn't work on the new Touch works perfectly well on the old one, and on the iPod Classic.
Does this throw any light on the matter? |
