quadrisproTheMuso, I'm very happy to have another ubuntu-guy in the team! Please join #debian-multimedia on OFTC18:28
quadrisprohi persia!18:28
ScottLi hoping to have an SRU for the ardour mute bug for 10.04.118:49
ScottLhttps://bugs.edge.launchpad.net/ubuntu/+source/ardour/+bug/58178618:49
ubottuLaunchpad bug 581786 in Ubuntu Studio "Mute button not enabled by default in Ardour 2.8.6 Lucid AM64" [High,Fix released]18:49
ScottLsince no one made a patch for the qjackctl renamed port bug it can be handled by backports18:50
ScottLhttps://bugs.launchpad.net/ubuntu/+source/qjackctl/+bug/49043618:51
ubottuLaunchpad bug 490436 in qjackctl (Ubuntu) "port renames are ignored" [Undecided,Fix released]18:51
ScottLsince the ardour bug includes a malformed configuration file and creates an incorrect configuration file in the user's home directory it needed to be handled via SRU18:52
ScottLthis prevents the incorrect configuration file which really can't be effectively fixed by a patch after installation18:53
ScottLhowever the qjackctl bug is easily fixed via update through backports18:53
ScottLi'll push for a backport next18:53
ScottLhi troy_s 18:53
troy_sScottL: Greets.18:54
ScottLtroy_s, i managed to take two videos and alpha one over the other using blender's node editor!18:54
troy_sScottL: It's relatively easy stuff once you wrap your head around nodal compositing.18:55
ScottLtroy_s, however, i've noticed that blender seems to drop some frames when compositing and rendering to an .avi file18:55
troy_sScottL: It shouldn't.18:55
ScottLtroy_s, oh, the nodal compositing is easy and it makes easy sense to me18:55
troy_sScottL: The main thing to note is that Blender _only_ knows frames.18:55
ScottLtroy_s, i had noticed it but expected the frame drop issue to be something i did, however someone (nonKlattu from #oggcastplanet) made a mention of it as well18:56
troy_sScottL: So if you have say, 100 frame piece at 29.97 (30/1.001) you will have 100 frames in Blender. The sync will be off if your framerate is set to say, 25/24, etc. (or even a  flat 30)18:56
troy_sScottL: Haven't seen it. Don't encode to Ogg Theora here - it's shite.18:57
troy_sScottL: Likely the encoder.18:57
ScottLtroy_s, i started with .png files that i created in inkscape...each frame contained a number that incremented and moved across the screen18:57
ScottLtroy_s, i created an .avi from these in VSE in blender18:57
troy_sScottL: You can also do what many do which is two pass the whole thing. Work in lossless still images and then encode to the flavour of your choice. Little more hd space, but much versatility and upside.18:58
ScottLtroy_s, then alpha'd over and dumped this to another .avi18:58
ScottLtroy_s, hmmm, didn't know that, i will explore it though :)  thanks for the direction18:58
ScottLtroy_s, oh, a friend of mine is going to help my video this using his HD camera...it's getting interesting :)18:58
troy_sScottL: Needless to say, I have yet to see Blender drop frames so it is almost certainly the encoder side of things. Theora isn't really all that up to snuff.18:59
troy_sScottL: HD is a misnomer.18:59
troy_sScottL: It is like me trying to tell you that a Tango icon will be better if we double the resolution.18:59
troy_sScottL: (Which, I'd add, some will try.)19:00
ScottLtroy_s, i rendered using ffmpeg and it worked fine, but created a .dvd file19:00
troy_sScottL: That's just the wrapper it denotes. In the encoding settings you can pick which wrapper and what internal codecs you can use.19:00
troy_sScottL: There is a bit of a misunderstanding between wrappers and internal codecs, as you likely know.19:00
ScottLtroy_s, i've been informed that HD means a specific resolution (something like 1920 x 1080) and some other stuff that i've written down but haven't mentally assimilated yet19:01
ScottLtroy_s, sorry, having two conversation in two channels...yes, it appears to most certainly be a codec situation19:01
troy_sScottL: There is HD and FullHD or TrueHD - 1280x720 in the former and 1920x1080 in the latter. Still a moot point.19:01
ScottLtroy_s, my larger issue with the HD is that since the bar is being raised i'll need to bring up my production a bit ;)19:02
troy_sScottL: There have been cameras around for ages that shot HD but they still look like poop regardless of what people try to say. It has to do with receptor size. Basically what you are loosely referring to in your head is cinema - trained up over your 30+(?) years of living and watching movies.19:02
troy_sScottL: It's funny, some think that when shooting HD over film. Not many people realize that film is roughly (depending on ISO and a plethora of other details) three times the resolution of HD.19:03
troy_sScottL: Anyways, the advent of DSLR motion picture work has brought that cinematic look into reality (with other issues such as skew of course.) It is the first time you can actually shoot cinematic looking things _ever_ - HD or otherwise.19:05
ScottLtroy_s, my friend at work shoots video for weddings and the such, so whatever he has is better than my $350 camcorder ;)19:06
troy_sScottL: Quality is a floating bar. The T2i shoots better quality (if we speak in an agreed upon language) than a 4000$ Panasonic HVX200 19:07
troy_sScottL: The main thing that the video camera of uber-expensive origins fails miserably at is aesthetic of look. The sensor is teeeeeeeeeny. As such, your lenses need to be much much wider to get anything to land on them (basically the projected image needs to be much smaller as it has to land on that sensor.)19:08
troy_sScottL: As a result, because we can't bend optics, the optical nature of the wider lenses remains - depth of field that sees far too much - nothing really out of focus.19:09
troy_sScottL: And _that_ smashes into your 30+ years of visual reading that you have learnt from the movie theatre.19:09
ScottLi've read some about DSLR in my Sound on Sound magazine, the prices are coming down a bit, even a Rebel(?) camera and record it19:10
troy_sScottL: So while you may not know what the difference between 'film look' and 'video look' is if I asked you, if I showed you would likely be able to spot it in a heartbeat. Soap operas used video cameras for example, as does some lower end television.19:10
troy_sScottL: The T2i is an incredible investment for anyone interested in motion picture work.19:10
troy_sScottL: http://www.bccamera.com/index.php?main_page=product_info&cPath=7_16&products_id=4401&zenid=uscutliaf8c5e9u1jhigmh6u6519:12
ScottLtroy_s, oh, i've also managed to get a delay in one of the videos starting after the other :) ..so i'm feeling pretty good about what i've learned so far, but of course there will be more hurdles i'm sure19:12
troy_sScottL: Just keep hammering stuff together.19:12
troy_sScottL: It will get closer and closer to those empty words known as "easier" and "intuitive"19:12
ScottLtroy_s, lol, it is already...the node editor is really simple and understandable to me...just the ignorance of which node i need is hampering me19:14
troy_sScottL: Once you get used to Blender, you may want to check out Ramen too. It has developed pretty well recently.19:14
ScottLtroy_s, i'm still wrapping up the lyrics and restructuring the song...then i'll rerecord it and finally i'll be ready for the video19:15
ScottLtroy_s, it's all a gas and cool to be able to complete all in house (literally!) with common equipment (more or less)19:15
troy_sScottL: Once you get all the technical stuff down, then it comes down to getting your head rammed into the nebulous 'how the hell do I create a compelling piece of work with pathos'19:15
ScottLtroy_s, hopefully, this can show what is capable for musicians, just like you did with the blender video you did19:16
troy_sScottL: Yeah I have no real idea why that thing got the legs it did. There is another one stuck in the pipe. Unfortunately another project has jumped ahead of it in the line.19:17
ScottLtroy_s, i was talking to someone in #oggcastplanet (i think) and they said it was too "artsy-fartsy"...i told them, DUH, that was the point!  LOL19:17
ScottLtalking to them about your video, that is19:18
troy_sScottL: Well ... that's an accolade. The day that I see things on the same aesthetic level that the ridiculous ftarddom does in our culture will be the day that I will happily lay down.19:18
troy_sScottL: Seriously... that's like having someone at McDonalds criticize your food.19:19
ScottLtroy_s, and i suggested to a few people that we could do a compilation album to show off linux based music so that we individually didn't have to do so much work but get a product out there...this might have some legs too :)19:19
troy_sScottL: Our culture is busted.19:19
troy_sScottL: The main problem is that it is one thing to have the distribution and tools at our disposal. It is another to deliver a bloody product that has emotion and is appealing to a given audience.19:19
ScottLtroy_s, well, they said the liked it and it was impressive19:20
troy_sScottL: If it were all easy stuff, people would be doing it everywhere. The monetary cost isn't even a factor - you have huge studios trying to tickle that nerve with bottomless pockets.19:20
troy_sScottL: While I was going through Uni I remember very vividly the 'If only I had the...' syndrome. It is though we wrap our failures up in the belief that some external thing was the governor between our ability to deliver something.19:22
troy_sScottL: You would need to have a very clear picture of what you want and figure out how to get it. Music wise that is.19:23
troy_sScottL: I'm not entirely certain there is a large enough body of work out there to pull the most compelling bits out of it.19:23
ScottLtroy_s, the T2i you linked is the camera that the SoS magazine reviewed :)19:23
ScottLtroy_s, oh i agree with music and the believe that a new piece of gear will make you or your music "better"19:24
troy_sScottL: It's the best option for anyone wanting to shoot motion. Deadly affordable and delivers a solid look because of the huge sensor (in terms of motion picture work.) APS-C sized sensors are smaller frames than traditional SLR, but they are identical in width to professional grade motion picture film camers (24mm wide as the film travels vertically)19:24
troy_sScottL: It obviously would be near impossible to create an Olympic swimming pool with only a shovel, so I'm not ruling out the particular need for certain bits.19:25
ScottLtroy_s, i've secretly admired tom morello of rage against the machine because he sticks to a pretty small subset of equipment yet is inventive as hell19:25
ScottLtroy_s, also in my last band the singer/rhythm guitarist was deluded about equipment19:26
ScottLtroy_s, both are examples of why i try to stick to my stock equipment and explore myself to be more inventive and creative19:27
troy_sScottL: Equipment is a weird thing. I'd hope that the vision always comes first and that the gear is always subservient to that vision. If the gear must come along to serve the vision, so be it. But when the gear leads the vision, there was likely no vision there at all.19:28
troy_sScottL: (Unless of course you are communicating precisely on that wavelength perhaps... making a statement as Mr. McLuhan would have said...)19:28
ScottLtroy_s, do you remember which format you rendered out your blender video?19:30
troy_sScottL: mpeg4 iirc.19:30
troy_sScottL: May have been an x264 pass for YouGoo? Not entirely certain.19:31
troy_sScottL: There is some secret mojo you can encode to for YouGoo that doesn't get a full re-encode.19:31
ScottLtroy_s, obviously i need to explore more about rendering options, and i shall19:41
troy_sScottL: Don't sweat it too much... just worry about creating the bits. Encoding is another matter.19:42
