You know about this stuff--fix it for me. And explain the weird deinterlacing artifacts, too.  |  IP: Logged Leo Enticknap Film God Posts: 7474 From: Loma Linda, CA Registered: Jul 2000 posted 06-25-2008 10:38 AM                        Cat weight lifting, Japanese style.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 06-25-2008 01:14 PM                        Does everyone already know that YouTube preserves stereo audio in uploaded videos. If a video is not playing in stereo, and a stereo version exists, you can usually get the stereo version by adding "&fmt=18" to the end of the url. This also gets higher-quality video if available. Phil's "Jeepster" in stereo (unfortunately the audio sounds like it's been through several iterations of lossy compression) YouTube used to encode everything as Flash video with MP3 audio. If you uploaded in Flash format (.flv) and were very careful about limiting the total average bitrate of a file to a max of 350kbps, their servers would accept 128kbps stereo MP3 audio without re-encoding it. That trick left very little bandwidth for the video though. Recently YT switched to encoding in MP4 or H.264 video (I forget which or maybe they're the same thing) and AAC-LC audio. It appears that they re-encode every upload, no matter what format or bitrate the file may be in, so if you upload a file with uncompressed PCM audio (CD quality), it will only get encoded once. If you want the best quality audio, it makes no sense to encode it yourself with some type of lossy compression, then hand it to YT who will then re-encode it, causing degraded sound. (Downside: This makes the size of the uploaded files much larger) Also, in my experience it may take as long as 24 hours for the HQ stereo version to become available. So if you aren't getting stereo on the initial upload, wait a while and try the "&fmt=18" trick again later. Example of a CD-quality PCM upload that's been re-encoded by YT with AAC at approx. 128kbps: I'm Your Boogie Man - KC and The Sunshine Band I went to a little extra work on this one to declick it and applied some mild EQ. Please, nobody make fun of me. Making these videos is just a hobby and I don't necessarily like all of this music. Maybe I do. Maybe I don't.  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 06-25-2008 01:44 PM                  quote: David Stambaugh ...you can usually get the stereo version by adding "&fmt=18" to the end of the url.

Question: What happens if there is no stereo version available? Does it still play but in mono without crashing?  |  IP: Logged Chris Slycord Film God Posts: 2986 From: 청주시, 경북도, South Korea Registered: Mar 2007 posted 06-25-2008 01:50 PM                     AFAIK, adding that part to the link just lets it play in the highest quality that youtube has for that video. So I would assume if the highest quality version is mono, it'll play mono.  |  IP: Logged Tony Bandiera Jr Film God Posts: 3067 From: Moreland Idaho Registered: Apr 2004 posted 06-25-2008 01:51 PM                     A serious electrical accident...watch closely from about 1:00 - 1:25 ARC FLASH INCIDENT This is a chilling reminder of how dangerous electricity can be. The tech was "racking in" a circuit breaker after maintenance. It was not racking properly (look closely and you'll see him cranking one direction, then another,, then back again.) An expert from another website speculated that the cause of the explosion was the "primary contact fingers" were misaligned and the force of the tech trying to rack it in caused them to touch and short out. This, for me, is way to similar to an actual accident I was witness to, where and electrician was fried by 12,000 volts in a similar set-up. That poor soul was literally a blue fireball for far too long until the power was cut off. It haunts me to this day.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 06-25-2008 02:45 PM                        The "&fmt=18" trick seems to always work. If no stereo version exists, you'll just get mono.  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 06-25-2008 03:22 PM                  BANGLES - "WALK LIKE AN EGYPTIAN" Great Cover by the Generations - "Walk Like an Egyptian"  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 06-25-2008 05:36 PM                        Scott, those weird interlacing artifacts are because you didn't de-interlace it before uploading to Youtube. Since Youtube is professional quality, it ONLY works in progressive scan. Professionals don't use interlace! Ask Youtube! Also, what sound format was the audio in whatever file you uploaded in? It was probably not a supported codec.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 06-26-2008 04:36 AM                     Skateboarding under cars  |  IP: Logged Justin Hamaker Film God Posts: 2253 From: Lakeport, CA USA Registered: Jan 2004 posted 06-26-2008 04:55 AM                        Tony, thanks for the reminder about why I HATE working with electrical. I had to change a breaker on a Christie lamphouse a few months ago and I thought the master breaker was off. I'm so glad the wire I touched was only 110. I'm not afraid of anything mechanical but I HATE dealing with electrical. Even changing the ballasts in fluorescent fixtures scares me.  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA. USA (1774.21 miles northeast of Dallas) Registered: Jun 99 posted 06-26-2008 01:45 PM                        Joe--how do you deinterlace an MOV file? I'm using the SGI "mediarecorder" tool that comes with the operating system. It sucks, and the workstation is a decade old, but I don't have anything else with a video capture card at the moment. And why would Youtube only display progressive scan content? Doesn't most Youtube material originate as interlaced NTSC or PAL video? Not sure about the sound codec, except that the original file had no sound, so I don't really understand why Youtube decided that my file needed random bursts of static added to it. It didn't happen when I used the same tools in the past.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 06-26-2008 03:42 PM                        You deinterlace before it gets to Quicktime. Do it in whatever you are editing in. Youtube can ONLY display in progressive scan because not many (if any) computers run in interlaced mode. So it is playing 60 different moments in time 30 different times a second. One thing you could try for an "auto deinterlace" is make the Quicktime file exactly half of the original file in vertical resolution. So if the original video is 720x480, make the Quicktime 320x240. Be sure to add an audio track, even if that audio track is silent.  |  IP: Logged James Westbrook Phenomenal Film Handler Posts: 1133 From: Lubbock, Texas, Usa Registered: Mar 2006 posted 06-26-2008 03:45 PM                     David, Thanks for getting "California Strut" by Walter Murphy stuck in my head.
