Help me with GZDoom mod Intro!

Almost worked, but it's a little little faster than the sound, it's delayed by a second.

This is weird.

Anyhow, you can try playing with "setpts=1.0*PTS", just changing the 1.0 to 0.9 or whatever, should slow it down. (can't actually remember if it was the opposite, sorry).

Here you go: intro.pk3 (a zip file)

I used the following commands with ffmpeg to convert the video:

ffmpeg -i input.mp4 -c:v libvpx -b:v 1M -an output.ivf
ffmpeg -i input.mp4 -vn -c:a libvorbis output.ogg

The sound needs to be provided by a secondary file with the same name. So if you have intro.ivf, the audio for it must be in audio.ogg.

umm.. A single search (ffmpeg cli arguments) got this as the top result:

https://www.ffmpeg.org/ffmpeg.html

6.3 is what you want...

Yes i DID IT, BUT THE SOUND is misplaced, it's in the wrong spot, it's cut or idk what. I can send the file if you want. Can't even desribe it properly, maybe the intro speed is somehow slower.

First, you should just check if the video and the audio length coincide, if not you have to adjust one of the 2, or, if during the video conversion something went "wrong" (video is sped up or something else), you should make another conversion.

The video is longer than the extracted sound. I tried to convert it many times, the thing that showed in the console I noticed was the video speed changing in some places, how can I make ffmpeg not do this?

I used another command to get the intro that I got from here and slightly adjusted (I still barely know what I'm doing, so I bet there are better ways to do that)

ffmpeg -i YourFullFilePathHere\VideName.mp4 -s 960x540 -crf 12 -b:v 50M -minrate 25M -maxrate 50M -bufsize 35M -r 30 -filter:v "setpts=1.0*PTS" -preset slow VideName.ivf

You can specify the video quality you prefer, also I would not recommend to go for an aspect ratio bigger than 960x540, or you'll  get quite big files that would make your wad massive for just an intro.

Thanks, but I still don't know how to use ffmpeg

 

I made a new intro, everything works but the sound is misplaced, what's going on?

What? I don't understand what you are trying to say

The IVF video will have no sound by default. You need to extract the sound into a separate file with the same name, except for the extension. So, if you have intro.ivf, you need to put intro.ogg in the same folder of your WAD.

For some reason, GZDoom cannot make use of the audio data from an IVF file -- I believe this is because animations and audio rendering are different subsystems, and the audio subsystem doesn't know how to play the audio track from video files.

Anyways that means that you need to provide the audio as a separate file. Look at what @Worst did:

That's basically what you need to do as well.

Or you can take a look at this thread:

Hopefully it'll be more clear. I can't explain it in simpler terms.

hey i know im late to this but i cannot figure out ffmpeg. my .bat file is ffmpeg -i C:\Users\thegr\Desktop\ffmpeg-n6.0-32-gd4a7a6e7fa-win64-lgpl-6.0\bin/intro.mp4" -s 250x200 -crf 12 -b:v 50M -minrate 25M -maxrate 50M -bufsize 35M -r 60 -filter:v "setpts=0.5*PTS" -preset slow intro.ivf however it does not appear to work for me so if anyone can help out i'd appreciate it 

(for context not working means when i use the bat it does nothing)

Well, assuming that you are running your batch file from windows, then for starters you could try adding pause to your batch file after the line with the ffmpeg command. That way you can see if there is an error message before the console window closes. Like so:

ffmpeg -i C:\Users\thegr\Desktop\ffmpeg-n6.0-32-gd4a7a6e7fa-win64-lgpl-6.0\bin/intro.mp4" -s 250x200 -crf 12 -b:v 50M -minrate 25M -maxrate 50M -bufsize 35M -r 60 -filter:v "setpts=0.5*PTS" -preset slow intro.ivf
pause
