I sure wish the creator had put all the level vids together before releasing it.
I got it from the Speed Demos Archive here:

Main game list, in case your interested in checking others out, some of these videos have people making/taking INSANE shortcuts through some of your fav classic games that will make your jaw drop:

File directory:

There are 40 files for the levels with 9 per each of 4 episodes, plus 4 levels which have 2 exits, and thus, 2 videos each.

They are all 320x200 res at 30fps
with Xvid mp4 for video
and mp3 22khz stereo for audio

I used VirtualDub with direct audio and video stream copy, which produced a video that was flawless except for a little over a second of audio lag by the end.

The difficulty here is the near maddening task of trying to sync to video by eye because the events all of the SFX correspond to are all of us such damn low frame rates (4 for each I believe, that is: each action (traveling/attacking) has 4 frames in each of the 8 basic dirrections, same for player weapons). A problem which could be conquered on it's own, but this video is a speed run where everything is usually TOTAL chaos (tough to pick anything out), along with the fact that DooM's audio engine has an iron clad limit of only being able to play 8 or 16 sounds at once means more than half of the graphical action is silent in the wild and crazy later levels, ESPECIALLY in Ultra Violence skill level, and it becomes an excersize in futility trying to match it up manually.

I just know that there has to be a very simple way to get the compiled video to sync the audio throughout as well as it is in each individual video.

ALSO: I wish to put a single Image (for 1 second) in front of each episode and each level to just state which they are like "Knee-Deep In the Dead" or "e1m1" (but not level NAMES, those are on the scoreboard after each level) and then one final image for lets say 3 seconds with the total time.

Here is a screenshot to bring back memories:


-Laters, and thanks for your time!

p.s. I believe the audio engine may not even be update in the new enhance engine ports of DooM (also able to run Hexen, Heretic, etc) because as I recall id software licensed the audio portion of the game and never got, and eventually wasn't able to procure the rights to. and so it's source was not released along with the graphics engine.
