Can't Run SpeedEdit sound problem

[lvsoule]

Hi I got SpeedEdit downloaded and installed.
However when I try to open it up it says:
SpeedEdit can not run using DirectSound emulation. Please verifty that hardware sound acceleration is enabled. I've doubled check and the sound acceleration is enabled, yet it still won't open.

I'm using the onboard sound system on the motherboard. It is a Supermicro. Then I put in a couple different sound cards just to see if that would do anything and it didn't.

So just for fun- I switched out the video card just in case that would make a difference, but no change.

any suggestions
thanks

Maybe you have hardware sound acceleration dialed down in the directx control panel? Use the dxdiag tool to find out.

Hi I'm not sure exactly what you had me go into but I went into sound 2 section and set it to full acceleration & it worked!

thanks

I got the SE working on my computer. However mp4 playback has no audio. I was also hopeing that it would edit .wmv. It's easy to convert wmv's to mp4 though. I used Sorenson Squeeze to convert all my videos to mp4 and maybe it is not a valid encoder for SE???

The MP4 isssue is due to an audio codec that that requires...

[lvsoule]

so does that mean that SpeedEdit requires a codec. Or is it the codec that Sorenson uses? Is there a way to download the codec to make it work?

thanks

Don't know.

MP4 video files are usually AAC audio compression.

There is a disabled preference for DirectShow AAC and AC3 audio support.

This is disabled because many downloadable AC3 and AAC codecs are unable to seek properly and will cause lockups, high CPU usage or even crashes.

If you want to try a codec, find one on the web, install it, then open SE and enable this preference.

If you experience problems, make certain that you uninstall the codec, then try to find another one. (Sorry, I don't have suggestions off the top of my head) If you don't uninstall the known buggy ones, Windows may still try to use them.

At worst, you can disable the preference and SpeedEDIT will safely ignore them as it does now.

I figured out how to get the audio to work in SpeedEdit when working with mp4's(i-Pod compatible). The mp4 embedded audio never did work, but I took and converted the original mp4 file to mp3 inside of Sorenson Squeeze at 160Kbps(I could not get this to work in i-Tunes). Then I took and imported the newly converted mp3 file and placed it under the mp4 video on the SpeedEdit timeline and it worked. Note: make sure in the prefences that under the windows tab/preferences/editing/SpeedEdit offsets - that it is set to no offset on audio & on video. Then the audio will sync up well with the video & you can edit from there. This will be very handy for what I do - Hopefully someone finds this useful.

Good tip.

If you would like to keep your in/out offset preference most of the time, you can also select the video clip and press G to clear the in and out points. Then they should line up correctly.
