Video but no Audio...

[ghostology]

Hi,

We are ready to buy this software and think it will help improve our show which is a Radio/Video stream. We were testing the ability to play pre-recorded clips and stream through Livestream.

We have a mixer plugged into the mini-mic jack on the laptop like we normally do, and are able to stream via VidBlaster just fine with both audio and video... however, when we transition to Player 1 to play a pre-recorded piece, the video makes it across but the audio does not.

Any idea why this happens? Is there something I need to do to fix this?

Thanks so much for your help, we were ready to buy it and use it tonight on our show but we will wait until we can figure out why this is not working properly with our system.

Thanks so much for all of your help.

The audio needs to be played through your audio mixer. Attach a cable between audio out on your soundcard and one of the inputs on your external mixer.

Hey Jakob,

Thanks for the response. Doesn't that defeat the purpose of playing any mp4s, movs, wmvs, or avis through the studio? Im not sure Id be able to launch audio from one computer into our mixer and have it sync up with the pre-recorded movie we would like to play during our show.

Any thoughts on getting both the video and audio to sync up?

Thanks so much for your help.

You can read about this in the FAQ. When you play a file in Vidblaster the video is sent to the program monitor, streamer and the recorder. The sound is just sent to the soundcard. You use an external mixer to mix the sound from the file with any microphones you use. This gives you good controll of the different sound levels. Sync should be no problem since the sound just goes out from VD, through the mixer and back into VB for recording and streaming.

Thanks Jakob... well try it. :)

We are testing vidblaster on a laptop computer using a usb TV Tuner card for video and audio input. Vidblaster only allows you to select the video on the card but does not allow you to select the card also for audio. We have to input the audio directly onto the pc via the mic input jack.

This works fine but It would be nice to be able to select the tuner as audio input instead.
The other issue we are experiencing is that when we play a video clip in lets say player 1 we dont get any audio output to the stream.

It would also be nice to select audio from speakers as a source for audio input. This way vidblaster would use any audio played via the pc speakers.

Is it possible to have this included a.s.a.p it would help us with a project next month. This is really urgent.

Scruffy,

Welcome to the VB forum.

As a general custom, if you ask a question on on section of the forum, you don't need to ask the same thing in another section. I promise we'll get you answer! Please see your post in the General Support section for a partial answer.

As a general note: Vidblaster is designed to use a separate, stand-along mixer for audio. Other uses of mic-in and/or the audio portion of capture cards might work, but typically are not supported.

guys this does not seem to make any sense to me. Why do I have to install a wmv or avi file on my laptop to play in VB but have to take audio from the laptop back to a mixer and then back into my laptop? A laptop only has one mic input and headphone input. If I am already using the mic input to bring in the audio from the mixer then how do I use this same input to bring in audio from player 1?

Would'nt it be easier to just have a feature for VB to select audio from speakers? Or allow selection of audio for each camera or player module to allow selection or audio from speakers, mic or external hardware/software?
I need to has this clarified please , must use VB soon.

It all comes down to your sound card, integrated or seperate card. Also the software that comes with the computer or card. With so many configurations it is difficult for a single program,to be able to be compatable
with so may setups. I have tried VB on i7, Quad core desktops, and a Dual Core laptop. Each time I used a mixer (Berhinger) and connected via the following: Mixer output to computer audio input, computer output to Mixer input. By looping the mixer all sound is controlled by the mixer. In any case it takes alot of "tweaking"
as does any video or audio attempting to broadcast via streaming.

Hi

I agree that sometimes it could be useful to be able to choose "speakers" in the audio module. That would mean the possibility to send the sound from the Vidblaster players, one or several skype callers and one microphone to vidblaster for streaming and recording.

One problem with this setup is that the mixer in Windows is not a great tool for live mixing. By routing the audio out to an external mixer Mike has given us a better tool to create a good sound for our shows.

An external mixer frees up the mouse and computer screen for controlling video and player starts only. The producer can control the audio with the other hand or let another person work the audio.

Most of us use more than one microphone and need a mixer for that anyway.

To answer your question about inputs:
If you send the sound from the Vidblaster players out to the mixer and add the sound from microphones in the mixer you just need one audio input from the mixer to get all the sound you need for streaming and recording.

I choose to discuss this here even if you have asked about this in another thread as well.

Is it possible to just connect audio out from the computer to audio in on the same computer. Line in needs to be turned down on the computers internal mixer but this would be the same as routing through a mixer using only one channel on the external mixer.

The sound levels would in most cases (depends on the audio board) be controlled by the "recording section" of the windows mixer I guess. This would mean some problems with controlling the sound levels (I don´t know i´f there is a way to listen to whats sent to audio out) but in a simple show it could be done.

I don´t think this should be part of the help-file but for experienced users who like to "hack it".
Anybody tried this?

Scruffy,

When I first discovered VB in early 2009 I struggled with the way VB handled audio. After many hours of testing different setups and trying to make VB work the way I thought it should work, I finally accepted the way VB was designed to handle audio: through a mixer.

Yes, it does mean that we users have to do things that don't appear to make sense (like run sound from the PC to the Mixer and then back to the PC to make Players work), but that's the way VB works.

We can accept it and learn how to use it, or... not. ;D

I think there is no real chance that Mike will revise how VB handles audio based on your (or my) suggestion. He's made it the way he intended for the strengths that Jakob has so well identified.

So... try a mixer. :D

Tom,

Don't take me wrong I have been using a mixer to run audio for my live broadcasting for years. I am familiar with using it. It just hit me when for the first time I had a file clip on a PC and to get the audio to stream I had to take audio from that clip and send it to the mixer to get it back to my stream.

[weconverse]

Well, for those rare occations (just want to play a video clip) I take an audio cable and connects one end to line out and the other one to mic/line in.

Also heard about "virtual cables" - and that they might mess up the Windows mixers/players, so I stay away from them.
