Unofficial VirtualDub Support Forums > VirtualDub Filters and Filter Development > Easy To Use Fade In/out Filter

Posted by: dgdg Oct 25 2008, 03:49 PM

I'm looking for an EASY way to perform automatic fade in and fade out for video AND audio at the beginning and at the end of the video file (or selection) while converting MPG to AVI/DivX.

My idea is to load the filter in VirtualDup, specify the fade in/out time (e.g. 3 seconds) and start the conversion. Please no frame counting or external tools.

Is there any VirtualDup filter available, that can be used like this?

First , please stop call it VirtualDup.
Second, google is your friend.
Third, try this: http://home.earthlink.net/~tacosalad/video/fadefx.htm

Ps: I actually believe that u are making a better job with brightness|contrast filter and than edit his opacity in the Curve Editor.
Your choice.

Sorry for "VirtualDup". ;-)

I tried FadeFx. But it needs frame calculation and does not fade audio.

How can I fade in/out audio ?

These forums seem inactive, I am starting with VirtualDub, so I can't answer to your question.

There is no filter for fading audio at the moment (I requested that a few times) demux audio, do the fading with another software (audacity) and remux.

P.S.: fading video is simple by using the filter called "fill" and switch to blend-mode. The resr is done by using the curve-editor.

I know u already said no external programs and I am sure u already found another way, but here goes anyway: try avisynth and his http://avisynth.org/mediawiki/Fade.
U can use http://avisynth.org/qwerpoi/ for making the script and than just open the script in virtualdub.

But You can not render only the fade-parts, You have to re-encode the whole movie instead of just use the smart-rendering function.

Thanks for your suggestions! Unfortunatly there seems to be no easy way, expecially because of the missing fading audio filter.

So I still have to use Pinnacle Studio for this job (DivX conversion with fading), which is a very easy to use program but also very unstable.

For video files without fading I will of cause use VirtualDub.

One year has passed and I want to push this thread, because I still have no solution for my problem.

I'm still looking far a fade in/out filter that fades video AND audio in one pass together with rendering a video with VirtualDub.

I's very annoying that I still have to render most of my videos with Pinnacle Studio, where this fade in/out ist a standard function.

dgdg, the problem you have here is that it's *too easy* and *too common* to demux the audio file to .wav, then do the fades in something like audacity (already said.) Then, once the video is encoded, re-mux the faded in/out audio back to the video. This is how it's done. I doubt any plugin developer will *ever* create a plugin to fade in 'both' the video -and- audio. Why? Learn to do things as everyone else already is, audio is done separate and with tools that provide possibilities far beyond what a plugin for vdub ever could, it's how it's done.

Open your video file in vdub, set your audio to full processing and compression to 'PCM." Goto File... 'Save wav'... create the .wav file. Import the .wav file into audacity and fade in/out. While you're there, why not normalize the .wav and remove some noise too

Once you have your video done, re-mux the audio file to the video file, or, supply the audacity faded file for the audio source while you re-encode the video to .avi.

Take a leap, you'll do fine

Can I add my support for dgdg's request. I have been after a similar filter for vDub for years.

JBBR - I'm sorry but "too easy" to denux the audio, are you kidding! On a typical edit I need to top and tail the file plus remove 3 commercial segments, I can't imagine the complexity of doing this seperately on the video and audio streams versus managing both simultaneously in the curve editor.
