Aaarg.
If I already owned a DVX - the Andromeda would be mine by now !!! I agree, if you already own one & a mac it is the best solution. Keep up the good work Juan ! This is just the beginning. I read your post that Sculptor might, in the future, do up-rezzing, targetting 2K formats for film composition. Wow. I hope that Andromeda will be around as a solution to many cameras, in many ways, for quite awhile. Cheers, Benton |

Juan, am I right in thinking that you don't do PAL cameras?
Cheers Aaron |

Sorry for the late reply:

About recording the analog out, we don't currently have any plans to build a portable digitizer/storage solution, although I guess it is possible. Our current focus, however, is on providing access to real digital uncompressed raw video, as is common practice with the high-end cinematography cameras. Recording the analog output does usually yield better results than the compressed format, but it's a world of a difference from having access to the RAW data from the camera head. Digitizing the analog out is like attempting to duplicate an uncompressed WAV file by putting a microphone next to the speaker. Our system gives you the actual WAV file, and is more compact and inexpensive than something like a Wafian. I do know there are other companies working on self-contained digitizing solutions, keep an eye on NAB2006. Ken: I think your post correctly summarizes how users should look at this system...it's just another tool with specific strong points like everything else. We understand that, for example, somebody who already has a DVX and a mac will find our system a lot more affordable than somebody who has neither. But this is the same with many products, the HVX is a current example. In order to record HD, you either need to invest in cards(possily P2Store) or invest on a mac laptop to record anyway. If you buy a car, you need to buy gas, maintenance, insurance, registration, furry dice, etc. Aaron: That is correct, we currently do not support PAL cameras. Not because the system cannot be installed on one, but because the difference in the amount of data(1 extra frame per second, 100 extra lines per frame) exceed the current max USB bandwidth of the available computers. We would have to make compromises such as cropping the frame or not record full 4:4:4, which we would rather not sacrifice. Cheers, Juan |

Juan;
would you like to pass comment on why the Andromeda EIA1956 resolution chart referred to earlier shows the black lines as significantly thinner than the white spaces between them? my copy of the EIA1956 resolution chart shows the black lines as equal thickness to the white spaces; which is as it should be.

Hello John,
Can you be more specific? I looked at the trumpets in Photoshop just now, and I don't see what you are saying. I do see edges that lie within a single sensor element/pixel, so there are gray pixels between the black and the white. If you count the gray pixels as black, then the lines are thicker. If you count them as white, then they are thinner. Cheers, Juan |

Hey Juan;
Not much to add really; but if you look at the black vertical lines in the center square , the black concentric lines in the bullseye and the black horizontal lines on the 200 blind as typical examples and compare them with the chart for the HD100 it shows your chart black lines to be much thinner. The HD100 chart looks about right. For want of an explanation, it looks as if your chart has had the maximum photoshop plugin applied to it, although I'm not saying it has; but it looks like something of that nature.

It looks like there will be other solutions to doing what you are talking about...however, It really doesn't seem like any of them will be in the $500-$1000 range, that would barely cover the actual cost of the drive array! John: I dropped the image into photoshop, and I still don't see what you are saying. The vertical lines in the center are 6 pixels wide with 6 pixel spacing. However I think I know why the lines may appear thinner when seeing the image at full resolution. Remember that this image is logarithmically encoded. This means that there is literally no black, but the white/bright areas are still there. Thus, the 'gray' pixels that sit in between the black and white are pushed brighter by the logarithmic curve, and the black itself is pushed to gray. This makes the dark area look thinner, but if you look at it closely in photoshop you'll see what I mean. This is the same encoding used for scanning film because it uses more bits for the darks, where most of the the detail is. I'm not sure what you mean by 'the maximum photoshop plugin' but we didn't apply any plug-ins, this is standard output. Cheers, Juan |

Thats too bad, General HD is where it deserves to be. It is in the same price ballpark as the P2 HDV solutions, and provides many of the solutions that people in the HD/HDV forums are seeking.

I agree with Ken,
I think this should be in the High Def forums - this is where it will get play and raise the general discussion levels. But, whoever wants to find it, no doubt will... personally I feel Andromeda should be more widely known |

"Is Panasonic DVX Glass just flat out better then Canon XL2 Glass? "
I believe so... but thats jsut my opinion... of teh years ive worked with this range of cameras, i am yet find a better piece of glass. with virtually no Lens abherations, barrel distortion is only SLIGHTY visible depending on your lighting and only in full wide, flare is NICE... most people hate lens flares, but wth this camera, i actually USE flares to accentuate certain scenes and enviornments, static pickup (ie dust) is easy to manage... i found the that the DVX has the cleanest glass of the lot.. |

I think this is really a question about what to do with the normal Pana, so it belongs in two forums. We have a similar problem with the DIY Cinema Camera threads over at Alternative imaging, the 35mmSLR adaptors simply swamp everything. I have to go through every now and then to locate the odd thread on DIY cameras and subscribe to them (though I don't post to all of them). I haven't really advocated a separate forum for them, because there wasn't an active enough community. But this gives me an idea that ties in with Andromeda.
The SLR lens adaptor technology can be move to their own sub forum, all other alternative imaging products, including DIY camera and original Andromeda threads can be kept in the general Alternative imaging methods forum. Another idea would be to have an Alternative Camera (Alternative and DIY)forum under HD forums (very few alternative cameras nowadays are SD) or at least all the commercially released ones "Commercial Alternative Camera (Alternative and DIY)" forum and we can shove all those flash cameras into there too. Many times a thread might belong in more than one forum at once because of the subject matter, like this one. When we start a thread we could get to nominate which forums it is posted to, where a link to the thread goes in each forum. So you could post a thread like this in a Panasonic forum and a Andromeda/HD/Alternative Camera forum at the same time. Single thread so conversation never gets split up over different forums. What do you think Chris? |

I hope somebody gives us low cost high quality recording for all the low cost cameras out there. I did some estimates and it would be a cheap alternative for a 720p camera and people could opt for the expensive faster drives for the true 1080*1920 cameras. Hopefully somebody in the market will cotton onto this: Basic 4:2:0 8 bit 720p/25fps (around 32.5MB/s) is doable with two cheap consumer drives. 4:4:4 and 12bit 4:2:2 (around 75MB/s) is doable with four cheap drives but big. For HDV1080 4:2:0 8 bits it is doable with cheap drives, but higher bit rates, format, or true 1080 resolution requires fast drives. Some people claim that the Sony cameras (for example) are not outputting true 4:2:0 1080HDV format, but that the resolution reflects the unprocessed pixel shifted resolution, with a circuit that synchronises to odd formats than it would line up with more 720p data rates. If lossless or visually lossless compression could be used than the data rate would drop by 1/2 to 1/6th. I have contemplated in the past, that maybe Sony could have possibly included a servicing mode on the HC1 to examine every pixel through the component port If such a mode exists then it might give a true RAW 8-14bit bayer output 1080 (50-87.5MB/s). Still, I am interested in a platform to record uncompressed 4:4:4 pixel shifted Standard definition through component, I have a camera in mind. Will you be offering a box to do something like this Juan, or do you know of a cheap box? |
