Can't see video while playing

Hello,

I have one problem. When I'm trying to play video with audio (separated) to see if fits, I can hear only audio and can't see video. Any idea how to make it right? It sometimes works okay and sometimes it goes this way which is driving me crazy because I can't do anything.

Than you for the answer and help.

What Step are you in when you're trying to play the audio? If you're in the Audio Step, and Clip Mode with the audio track selected then all you'll see in the preview window is a speaker. You need to be in Project mode(click on the word Project just above Clip). This way it will display the video while playing the audio track.

I'm in "project mode". It's just doesn't work. I'm not sure if it's some codec problem (but if it is...why it works sometimes and sometimes not?) or Ulead problem.

Ok then we're going to need more information in order to figure this out. The simple method is to Please read this post, and return with as much of the information as possible.

If it is a codec problem we need to know what codec is being used. Bear in mind that avi is not a codec, it's a carrier or container format that can hold a myriad of formats (codecs) such as DV, DivX, Xvid. MOV files are also containers, that can use a variety of codecs like MJPEG.

Okay. I'm gonna try my best.

I'm using ACE Mega Codec Pack (http://www.free-codecs.com/download/ace ... s_pack.htm)

My video which I want to edit is avi and using Xvid codec for video and mpeglayer3 codec for audio. File size is 198MB.

Version of Ulead VideoStudio is 11 Plus.

First Xvid is a highly compressed format. It is a distribution format, not meant to be edited, but distributed over the internet. Yes I know that VS and others say they are able to edit the format, and they are, but most of the time with a great deal of difficulty.

Now since you know that video is using Xvid, you should go to the Xvid site and download the Xvid codec from there. Why? Because you're problem most likely lies with your installing a Mega Codec Pack. These most often contain a hodge podge of codecs, many that conflict with each other, not to mention with codecs already installed on your system.

So first uninstall the mega-codec pack. Then download the Xvid codec from their site found here: http://www.xvid.org.

You may also want to convert the MP3 audio to WAV. VS seems to handle WAV files much better. MP3 is not a real audio file. MP3 is a video file, that has the video stripped away. So at times video editors, such as VS, fails when it is given an MP3 audio file, because it is searching for the video part of that file, which of course is not there.

Many of us use a free and powerful audio editor called Audactiy, to convert audio files. You can get it here: http://audacity.sourceforge.net/

Okay. So I uninstalled ACE Mega Codec Pack, installed Xvid codec, converted mp3 to wav but still no video preview.

Have you been able to see the video, and now can not? There is one other possibility that would prevent this.

Go to Preferences (File>Preferences), on the General tab look for Instant Playback target. It may be set to DV Camcorder or Dual Head Device. Set this for Preview Window.

It worked. It was set to Dual Head Device. Thank you so much for help. Really, thank you.
