Problem playing Elgato encoded video

Can anyone help me work out why I can't play some video I have encoded myself ?

A couple of years ago I converted my favourite DVD collections to DIVX, and they play fine on my Mac, however having converted them to H.324 format to play on my Apple TV I have had good and bad results.

Many films play fine on the Apple TV, however some do not play at all, and my Apple TV seems to crash (I get an Apple Logo in the middle of my TV screen and then after a 10 second pause get the menu.)

Anyone come across this issue ? Are my video files incompatible ?

I used the standard profile in Elgato to produce the .mp4 video files, most work but 50% do not.

Any insights welcome ...

iMac 24" Intel + 7300 graphics, MacBook 13", Airport Extreme, Airport Express, Mac OS X (10.4.8)

Using the standard "Apple TV" profile in Elgato H.264 produces files with an .mp4 extension.

I have experimented with the Advanced settings in Elgato and have remedied the problem, though I did exactly what you're not supposed to do when troubleshooting and changed half a dozen things at once 😉

Rather than use "Automatic" settings, I set:
Aspect Ration=Wide.
Overscan=On
Framerate=25
AAC Audio=48Khz
Datarate=96kbps

Not sure which setting fixed it, but the movies play OK, and the quality is very good considering the videos have been encoded from DVD to DIVX to AppleTV.

Elgato have a users forum which is slated to go live today.

I should have read your post a little closer, although it doesn't say it should have been clear to me you were using the turbo stick and it's software and not the eyetv software which does export .m4v's when the export to tv is used.

One thing I note is that your datarate is 96 kbps, I assume this is your audio datarate and not your video datarate.

🙂 Yes, indeed, my math is the first thing to go after 3 glasses of wine, closely followed by my ability to speak.

I meant to say that the majority of my encodes with Elgato have been flawless in that they play on the Apple TV with the standard encoding settings.

I have just recoded a batch of 100 DIVX files to AppleTV format, and the first 50 worked fine, and the last 50 would not play.

I recoded the last 50, and strangely 25 of these play fine, and the last 25 don't. I'm going to have another go at tweaking the settings tonight - I found that 96kbps for audio cuts down the files somewhat and still retains fairly good audio, otherwise my .mp4 files come out at double the size of the original DIVX - a fair trade off.

I used the "Movie Inspector" feature in QuickTime to see if there were any fundamental differences between the files that played and those that would not and could not spot anything different in the stats. being shown for the two sets of files.


If all else fails, I can always go back to my original DVD's and rip them again, however was hoping not to need to expend several hours on this task (may as well just watch them on the DVD player instead.)
