Not all Videos Work w/ iTunes/iPhone/iPod Touch

[Mr530]

I have been converting .avi Music Videos to h.264 for my ipod touch, however, it seems like half the time itunes won't accept the video?

Is there some type of specific muxing? My only guess is that the original video of the ones that didn't work were DIVX.

Any specifics that I should make sure I have checked or unchecked?

Make sure you use AviSource instead of DirecShowSource

For some reason Itunes will not accept 2 out of 3 of the videos I encoded from x264s. Anyone have any suggestions. I encode all of my videos the same way. except the aspect ratio which is usually <= 480x320

ok i figured out the problem its because itunes does not accept 23.976 only 25 and the 29.??? ones. I encoded them to be 25 fps and they work. Only problem now is that they're out of sync, does anyone know how to get the video and audio synced? Thx

Make sure you use AviSource instead of DirecShowSource

Curious. Why do you say that? Something to do with fps?

[Atak_Snajpera]

If you convert avis using DirectShowSource you can get strange results. Audio out off sync ,encoded movie not playable on device (PSP) and so on...

[Mr530]

how do you disable directshow?

[Adub]

a.) you can't
b.) why would you?

If you don't want to use directshow, don't use directshow. Just use vfw.


If you are referring to Atak's post, then use
AviSource("clip") instead of DirectshowSource("clip").

Wait a second, I don't remember you saying you were using Avisynth.

What program are you using to convert your videos?

[Mr530]

I am using MEGUI.

I manually typed in AVISOURCE and I got roughly 1.5 fps which is unacceptable.

This item was accepted into itunes, but not my iPod.

what do you mean by vfw?

I had some of my MeGUI encoded videos being rejected on iTunes as well.

If you try to open the encoded video on QuickTime, do you get "Error -2202: a bad public atom was found in the movie"?

I've found that forcing the framerate fixes the problem.

Here are examples of AVISynth scripts I use for 23.976fps videos:

To encode video:

OpenDMLSource("video.avi",audio=false,pixel_type="YV12")
AssumeFPS(24000,1001)
LanczosResize(320,192)


To encode audio:

OpenDMLSource("video.avi",audio=true,pixel_type="YV12")
AssumeFPS(24000,1001)
KillVideo()

There has to be a better wy, I get like 5 fps this method (encoding) and i still can't figure out how to encode the audio. The main reason i want to use megui is that its semi-easy, many options, and its a lot faster than videora
