whats the technical video explanation for this EVP on youtube?

[coolhotfun]

hey ya guys.. said i wouldnt be back.. but wondering about your technical expertice in the video field.. heh.. ok so few days ago noticed on reddit in the videos section it said.. possessed youtube video. I'm there.. yeah right. So i click it and its this french video filming help guy just talking and at 55 sec the video freezes and the youtube timer stops but audio keeps playing. It was this totally loud and garbled, what seemed like an EVP. Electronic voice phenomena. Wasnt no continuation of who was talking in french before cause you can hear some words in english. Maybe its from another video. But yeah apparently this eHow france didnt even know it was at the end of their video cause its just been sitting there since 09 till somebody noticed it lately. And its getting a lot of plays over at reddit, but nobody gets into detail about whats going on technically.

Check it out here:

"6. Choisir ses valeurs de cadre"
http://www.youtube.com/watch?v=fPZmqMRF0iQ

so whats the technical explanation for whats going on with the video and why it stops but audio keeps playing. I never seen that on any clips. I think on some viewing devices it'll stop at the 55sec instead of continuing till the 1:20.. so if you cant view it, i think there's some links on the youtube page to where you can view it all recorded. So whats going on with it, video expert guys? heh..

I could give you the likely answer, but I remember your conduct and attitude on the previous thread.

You owe this entire forum a sincere apology.

The probable answer is exceptionally simple.

[coolhotfun]

yeah.. i talked about that at the start of the first post. I was just sour about not being able to pull it off for broadcast quality. Abandoned that idea. There shouldnt be any reason to lose my cool like that again. Very frustrating those broadcast specs and mov files with those containers on windows. So there ya go.. sorry about all that. heh..

back to the topic.. well found out if you use a youtube downloader site, and save the low quality flv you get the whole thing if you play it back. Can't seem to extract the full audio though. If i go to convert it with virtualdub direct stream both audio and video to avi, it stops at the 0:55. If i play the flv it'll behave like it does on youtube where the timer stops at 0:55 but the audio keeps going. At least its a way to get it offline.. if you try and save the high quality 720mp4 it'll just stop at 55 in playback.

Tried opening the flv in winamp and thought i could use the nullsoft disk writer to export a wav as it plays but thats only for wav or mp3.. not flv.. so it'll just play and cant export wav. Any ideas how to extract this audio?

[later edit] ok thought of using that crappy vlc orange pile-on player so re-downloaded it and ran it. Was able to use the convert feature and export the full wav.

can download that here

full audio from fPZmqMRF0iQ 44khz 16bit stereo.wav

ok.. so now you guys can tell me whats going on there.

[Nelson37]

Not as extensive as your attitude warrants, but, ...eh.

I didn't really bother to check the clip as it is almost certainly a corrupted file, a complete accident rather than an attempt to achieve any particular effect. The audio being longer than the video is something that is not at all unusual but usually the result of some screw-up that some players consider out-of-spec and won't handle and some will.

Corrupted audio can sound all kinds of strange. Nothing amazing or even very interesting about this.

[coolhotfun]

ok, where are other instances on youtube with similar results then?

[Cornucopia]

There you go again, questioning valid advice. Look, he could probably find some examples, but he doesn't need to back up what he said to prove it to you. In fact, I would guess that even if he gave examples, you would try to find a way to discount them.
You should just accept it. It is the most likely scenario, and one that both follows from a scientific analysis of how a corrupted file might be received, and from fairly common occurrences that I have witnessed.

Do you have a question that is NOT couched in confrontational tones?

[Nelson37]

I do not know as I am not interested in spending any time and effort finding such crap. It's amusement for children and not much more.

[jagabo]

It's obviously the work of a demon. Everyone who has watched that video is now possessed. Just like in the movie Ringu. You've been warned.

[coolhotfun]

not gonna get into arguements with people want to try and start something. Sticking to the topic. Here for expert video advice.

so you're saying that it becomes corrupted because the audio is longer. I tried a test file.. screenshot video recorded the screen and it was 15 sec long. Then took a 20 sec audio clip. In virtualdub did direct stream copy for the video and in audio had it use the 20 sec file. Uploaded that to youtube and it just stops playing at 15 sec. Doesn't have the timer freeze while the audio continues playing. So whats going on with that original evp file? Its obviously not because audio is longer. What would cause the timer to freeze and continue playing the audio. How can you recreate whats going on?

If you guys need some sort of site to download youtube videos you can try something like savetube.com

Try downloading that original evp file and if you have any video inspecting program, checkout if you can view anything of video after 0:55 sec until 1:20 that it was. Is there any sort of forensic video editing software that can try and view anything from corrupted video files? They got stuff that can get deleted files from hard drives. You guys are video experts so maybe somebody can inspect that original file. Is it that stuff after 0:55 gets corrupted?

Also found another example on the net of a youtube video where the timer stops but the audio continues. This one is just normal audio and doesnt have any evp's.

Not sure about underlying cause for audio distortions, but you can get the clip to freeze and audio to play longer on YT. It's dependent on the muxer used . For example this was xvid/mp3/avi muxed by ffmpeg. Vdub's avi muxer won't allow you to do that

Nobody said that.

The corruption isn't in the files you can download from Youtube. It was in the file that poster uploaded. That caused Youtube's conversions to screw up.

ahh.. see, thats what i'm talking about.. getting down to whats going on. So you were able to reproduce how the youtube timer stops and the audio continues.

now.. whats up with the garbled words then.. was that from the french guy talking? Any ideas on how audio can get garbled like that? Thanks for the straight dope about the matter instead of games.

[coolhotfun]

ok fired up a thread over at an audio expert forum.. see if they can explain whats going on with the audio here. And seeing if any of those guys can clean it up and remove the major distortion.. maybe can hear more.

There's still some video aspect to it though. Was in a paranormal forum and this one guy said:

"it has something to do with YouTube's audio sync issues, the degradation of audio and stretching from sync problems could easily distort the man's voice to sound like that. "

ok.. whaddya guys think about that? Any video aspect snafu that could cause this french guy talking to turn to that other than his camera melting or something. lol.. Have you ever heard anybody's normal file get garbled like that? I dont think what that guy's talking about would take this french guy talking and make it sound like that. If you'd try "sync problems" i dunno if it'd do that. Hows about you video experts try and test things out with video snafu tests and take that french guy talking and see if you can make it demonic.

[coolhotfun]

Tried that ffmpeg program but couldnt get it going cause it seems like its command line. Looked around for some other type of muxing program. Tried MKVtoolNix but it exports .mkv. ok so took the original "6. Choisir ses valeurs de cadre.mp4" 720p downloaded from youtube. Opened it in virtualdub with direct stream copy for video. Set the range to end at 55sec bit before where it craps out. Exported that as an avi with original direct stream audio. Opened the original mp4 in sound forge and just copied some of the french guy talking and pasted it at the end. Cropped that at 1:20 where the old one was supposed to stop. Saved that as mp3. If i try and merge those together, the 55sec video with 120 audio in virtualdub and upload it to youtube, it stops at 55.

Tried the mkvtoolnix.. used the 55sec video and had it use the 1:20 audio and export that as an mkv. If i upload that to youtube, it'll do where at 55 the video freezes and the timer freezes but the audio keeps playing. There's no distortion in the audio though its just him continuing to talk.

On another forum a guy said:

"The video was encoded in a way to trick youtube to think it's shorter than it actually is, so when the VIDEO part ended, the AUDIO kept encoding, and the trick is tricking Youtube into thinking it has ended. Youtube doesn't know this 100% but part of the system detected the end and tries to encode the leftover audio portion and ended up compressing them together, hence the 'demonic sound'."

Well.. shouldnt it have tried to compress them together and garbled up that audio? Well.. what is going on with that original file which would cause the audio to do that?

anyways.. here's that mkv, you can try uploading it to youtube and see that it keeps playing the audio after it stops.

6. Choisir ses valeurs de cadre - 55 sec of original video muxed to 120sec of original audio.mkv
http://www46.zippyshare.com/v/99498376/file.html

the zippyshare has a video player but i guess it cant handle mkv files so its a black screen.

ok.. so tried to recreate what that guy said would cause the artifacts if you try and squeeze that much audio into it, and didnt do as the original did. Any other ideas, guys?

[Cornucopia]

We have better things to do than do YOUR work trying to degrade audio+video.
Your original question has already been answered.

Scott

[Nelson37]

Not many people here will waste much time trying to screw up on purpose.

No one cares but you. By all means, if you wish to investigate this, have at it. If it keeps you busy and quiet, I for one am all for it.

Trying to re-create a random file corruption is a fool's errand. As demonstrated.

[coolhotfun]

I don't see any "experts" successfully able to recreate whats going on in the "paranormal" video. They did say it had to do with a shorter video and longer audio that would cause it to garble like that, but I recreated it and debunked your theory.

1 for me, 0 for you, and an assist to the muxing guy.

ok wizards.. get to work and figure this one out.. cause so far, y'alls ain't no experts.

[coolhotfun]

aaannddd.. this is what i think of that groucho pest.. nevermind the nelson muntz sidekick. fail.

[Nelson37]

And you have reverted to your true nature, as expected.

You want people to spend time trying to re-create a random event, or at least to simulate one. It's a pointless, stupid thing to do.

Bye-Bye.

[coolhotfun]

i noticed nobody's recreating it because they're unable to. Want to proove what you're saying, thats how you do it.. not things like "i'm too lazy" or "i don't feel like it". So you're not prooving what you're saying is true.

Let me get this straight. Here you are, demanding someone recreate a glitch-- a malfunction that results in a muxed media file containing a corrupted video stream, but an uncorrupted audio stream, so that a web player (setting its timecode to the interrupted video stream) will continue playing the audio after the the video stream and timecode cease. Do you expect anyone to be so stupid to purposely sabotage a data sector on storage medium in order to satisfy your whims? Who the hell are you that anyone should feel the need to prove something so asinine? You asked a question, people answered it, but you didn't believe them. That's fine. Who gives a sh!t what a petulant child like you believes? You have no friends here, and no one is going to lift a finger to convince you of anything. Believe what you wish to believe and just go away.

[deadmeow]

Sounds similar to an EVP, but it seems to have the same pace as the video's speaker. Although there are real EVP's out there that respond to people's questions and actions, this audio seems to be a glitch, though a spookie sounding one.
