I have been using handbrake to convert my DVDs. I have noticed that on some there is a 1 to 2 sec loud static noise at the beginning. What could be causing this noise? It only happens on maybe every 3rd file. Not that big of deal, just curious. Thanks

How are you ripping these DVD's to the HD, what setting in HB are you using. Do the files play fine from your HD prior to running through HB.

Are you hearing the loud static when playing the HB file on your computer or when played through the ATV

The files are on a EHD in .iso format. I am converting the .iso to mp4 through HB using the Apple TV settings. Yes, the files play fine prior to converting.

The loud static happens through iTunes and ATV 2G
 
what are you using for speakers?

DTS will sound like static if you don't have a decoder. It's possible that the appleTV is fading the sound in for the first couple seconds, which will distort the signal enough to not be able to be decoded. once it reaches full volume, the decoder recognizes the signal and kicks in.

purely a guess though, and not even sure the appletv will handle DTS.

your answered after i started writing, so maybe that's not the problem if it happens in iTunes also.

the speakers: just the iMac speakers when watching in iTunes and the TV speakers when watching on ATV

DTS: interesting. I will have to look at the files this evening. Like I stated it is just for a few seconds. the sound sounds great after that...not really an issue for me but if i can correct going forward that would be great...
 
I get the exact thing that you describe in the OP. Well, except it's not seconds, usually only millisecond static sounds. I've also tried on my phone and ipod, it's the file itself that's the issue, not the ATV.

I rip from DVDs, and use the Apple Universal setting, nothing extra special. All I have to do is just re-rip it and the second time is usually fine. I can't think of a time where a DVD did it twice+ in a row.

Also, I usually just play the first few seconds of the video via VLC player just to doublecheck before adding to my iTunes library :)
 
I can jump in here and say I am experiencing the same noise at the start of Handbrake'd movies with my TV 2. I use HB 0.9.4 64bit and the AppleTV profile.
 
I was getting this same issue with some movies while using a customized version of the :apple:TV setting. I've since switched to using the High Profile setting and have not had the issue since.
