I don't understand why this is so difficult. I have tried a version from 2012 and I just got the current Windows 64 bit version.
I want to fade my video clip out at 5 seconds and fade back in at 10 seconds. So I go to filters > fade out > s, 5 > press ok > fade in > s, 10 > press ok. Nothing changes in the video or the preview window, even with "Played filtered" checked. What am I doing wrong? I tried all different times, seconds, milliseconds, you name it, doesn't work period.
In programs like Sony Vegas or Windows Movie Maker it's just a simple drag of the mouse on the video clip.
Should work, check made steps and demo video:

I followed your directions and I was ABOUT to say it doesn't work, but I figured it out.
The problem is the way fade in/out filter is worded. I don't know if it's different on the Linux or Mac versions, but on Windows it goes like this.
Left to right
&Start time (ms:) 0 h: 0 m: 0 s, 0
& End time (ms:) 0 h: 0 m: 0 s, 0
So I was putting in "s", 5, thinking that it was 5 seconds, but it must be 5 milliseconds or maybe it's 5 hours, who knows? I tried the ms column before, but you can only put 2 digits. 50 milliseconds is not 5 seconds.
Basically what I wanted to do here is join similar clips and have a fade in/out so they would transition smoothly. So I appended 4 clips and then set the fade in/out filter and saved the file. It did work, but it's not perfect. The transition to the next clip sort of has a hiccup. Doing a cross fade in Sony Vegas is definitely an easier method, for both the audio and video. Perhaps the Avidemux team could think of adding a way to cross fade clips?
Anyway I appreciate your help. I suppose the fade in/out filter is better suited for a full video or one clip, not clips appended together.
avidemux is not a full-fledged video editor :
QuoteAvidemux is a simple tool for simple video processing tasks. The keyword here is simple: it does not offer tools like a timeline, multitrack editing, you cannot freely move or splice audio and video clips from various sources. However, Avidemux allows you to do elementary things in a very straightforward way.

Perhaps you get a better result just using Filter
-
Black replace a section by black
between the appended clips.
