Hm, using Dosbox 0.73 which I downloaded from dosbox.com some time ago, I've recorded a bit of the Xwing Collector's CD for a friend - the results can be seen here
.
http://www.youtube.com/watch?v=bU2v1CFOn3M

And I have question about the best way to get general MIDI music into dosbox recordings, using free tools. Here's how I made the youtube video linked above.

1. CTRL-ALT-F5 in-game to start Dosbox .AVI capture, for game footage and digital sound effects.

2. CTRL-F8 in-game to capture raw MIDI commands.

After recording the segment -

3. open captured .AVI in VirtualDub - save video clip's audio track as a .WAV

4. open captured MIDI commands in Winamp with output plugin enabled, thus recording MIDI playback into a .WAV

5. open both .WAV's in Audacity and combine and save them into a single .WAV

6. open the original .AVI in VirtualDub and select the new combined .WAV as the audio file.

7. save the final .AVI

_____________________________________________________________

Ok so its convoluted and also the new compressed .AVI that VirtualDub produces looks significantly worse than Dosbox's .AVI and is more than 4-times as big! This is using the Cinepak Radius compression codex in V-Dub.

So..

Am I making things too hard on myself as far as getting general MIDI soundtracks into Dosbox recordings?

The video looks a bit "smudgy" but that could be the recompression. I didn't do any recording myself yet, so I'm wondering: how do you sync the MIDI track with the digital sounds one? You could use a better soundfont for the MIDI track, the recorded music sounds a bit tinny (; .

Also: you're using a mouse for playing aren't you? I have to get back to TIE Fighter soon, stopped playing for some reason (I'm afraid it was the "impossible mission syndrome"). Those two games are just amazing.

A mouse? Never. I'm using a CH Fighterstick USB ...

The pilot proving ground requires quick tiny movements, so I'm kind of flicking the stick to line up targets, so it does look a bit mouse-like. You'd see it was a stick if I made a long continuous turn.

Anyway, the MIDI track isn't perfectly synced with the digital track, since I started recording MIDI commands a moment after firing up the video and sound-effect recording. As a result, I had to snip a bit out of the MIDI's .WAV once i had it in audacity, so that the two tracks matched up better - and they're still not perfect...but I don't think it's noticeable.

And yeah, Winamp seems to be using a different sound-font then the one that's set in my windows control panel...I guess it has an internal one...did you hear how it slipped a grand piano into the audio track at the beginning there?

I didn't feel like messing around with it too much, but will adjust in the future...

I'm workiing through the Tie-Fighter Collector's CD as well. Brilliant, better than I remember it. Just took on 3 escort shuttles in a tie fighter in Tour 1 mission 1 -

gotta remember not to try that again...

You don't need to recompress the video when adding the audio. In Virtualdub just select Direct Stream Copy from the Video menu.

I'll try that, the first time I saved the new .AVI that's what I believe I did, and the resulting video was over 4gb in size, which was startling considering the Dosbox original was 40mb....

didn't look like it upped the resolution or anything...

You most likely saved it WITH processing but without compression, the stream copy
should directly copy whatever codec/compression was used before for that stream,
so not changing the file size (minus effects from the audio processing).
