Prospect HD and its HDLink
David.
No hurry in this enquiry. It might even be a case of me confusing myself. When I downloaded the Prospect demo, I think that after I installed it, the HDLink showed or the Premiere project preferences showed a 2k option and there was a 4k to 2k conversion utlity. However since legitimising the software, I have not been able to find this option again anywhere. I might also have seen the option on a website somewhere and maybe my recall is wrong. I took the AspectHD to ProspectHD upgrade month of May $400 meal deal. This apparently includes Neo as Neo does show in the list on the upper left of screen when HDLink is started. Where I am at is that I have a test of 100 frames of DPX files on two DVD data disks which I have copied onto one of my drives. They are identified as 4K files on the printed disk label. Neither Premiere Pro 2 or HDLink recognise the files. In a reply to a previous enquiry there was a mention of a function to convert the 2K files to Cineform yet to come as an update. So my question is - Will Prospect HD with Neo eventually be able to convert these files to a Cineform intermediate by similar operator processes that HDLink provides for m2t files or will another upgrade have to be purchased? My Super16mm/HDV origination project will be finished to DVD-Video so a DPX export is not needed. Sorry I am not more clear. Computers are not my strong point. Prospect seems to be doing its job as letterboxing does not seem to introduce occasional bands on transitions like AspectHD sometimes did. |
Thank you. Yes 2K with 4:4:4 support is very nice. :)

DXP support is coming and it will be a free upgrade to all current users. In the meantime us After Effects for your DPX conversions.

Ready to graduate to prospect, how to use? :)
ok just installed the trial of prospect hd. I know nothing about it cept for reading on cineforms site about how it's better than aspect and that it will improve my quality even from my hdv hc3 and A1. so how do I import and edit so that it's 10bit? use the propect hdlink? I know it's not true 10bit b/c it's from an 8bit source. But the site was showing/saying how it's better than 8bit to 8bit :).

Use HDLink or directly capture in Premiere with the CineForm capture module -- either way is the same quality. The quality advantages of Prospect HD, do not so much occur upon capture, other then support for 1920x1080 and 10-bit sources if you had that. For 8-bit sources the advantage comes when doing color correction, as you now have headroom to support pushing the image around without introducing 8-bit aliasing artifacts like gradient banding or contouring.

Prospect with HVR-V1
A while ago I updated from Aspect to Prospect, and I have a couple of comments:
1) Does it take quite a bit longer to convert Sony HDV to the 10-bit Prospect intermediates than it did with Aspect? 2) If so, is this because I'm choosing to upconvert the rez from 1440x1080 to 1920x1080 and/or from 8-bit to 10? These are great features, so no gripes, just curiosity. 3) Hats off to your coders, while the above is processing, all four "processors" (two dual core Opterons) are at 99-100%. Also, let me re-submit my semi-annual request that ingest of 35 Mb/sec XDCAM HD be added to Prospect. The "prospect" of this (pun intended) is one of the reasons that I spent the extra money to upgrade. Is there a timeline for full XDCAM HD support? And finally, good luck with your Mac plug-in. Because of their 422 codec I fear you'll have a tough row to hoe. Please don't give too much of your mindshare to that project and lose focus on your thriving PC base. I noticed the .mov file type and realized how deeply this is going. But of course I wish you well with all you do. Tip |

Prospect HD / Sony Z1U / Intensity Pro / Cineframe
I have a question about using the Z1U in Cineframe mode along with Prospect HD and the Intensity Pro card from Black Magic.
If I capture from my Z1U in Cineframe 24 or 25 using the component out into a Black Magic Intensity card using Aspect or Prospect HD (still trying to save up to upgrade to Prospect) will the capture do the same frame interpolation stuff that it does from tape? IOW, will I end up with a 24 or 25P capture? Thanks, Jim |
Yes, you will get 24p / 25p captures, with the caveat that Z1U's 24 mode has an non-standard shutter timing. Use CineFrame25.

DPX export problem with Prospect 2K
1 Attachment(s)
There seems to be a trouble with the cineon exporter filter and Prospect 2K.
I was trying to export some DPX sequences but somehow when loading them in Scratch they were not LOG, I rendered again and same problem. When I open the shot in Photoshop It was linear too. I did another export from my Laptop, in wich I only have NEO player installed, Same sequence, Same export and render parameters. And that render looks right. |
Where you running one in 16-bit and the offer in 32-float AE mode. The importer in NEO Player and Prospect 2K are identical, so the must other operation difference.
|
Both was in 32 bits, Maybe I had a colorspace applied in one of the compositions, disabling colormanagement did the trick.
|
I supose AE is confused when your are exporting to cineon and at the same time you have a colorspace applied to the project. And somehow it renders giving preference to the colorspace and not to the cineon exporter values.
Does it sound logical or is another thing? |
Your theory is good. The ways of AE sometimes surprise us also.

Hey Sergio, what that looks like to me, is I've seen "linear" from the camera, and your "linear" image doesn't look like a truly photometrically linear image from the camera. Instead what I think is happening is that you're exporting LOG, but the color management in AE is then taking your LOG image and converting it to some type of "print" gamma correction, since that's what the final image resembles . . . it's too bright, especially in the midtones, to be photometrically linear. A photometrically linear (which is a true "linear" image where doubling the pixel value is equal to double the real-world brightness) representation would look VERY dark, in that you would have hard time making out your subject's face, and only the windows would be visible, and most likely hard-clipped (i.e., no knee). I could be wrong, but this is my observation from seeing LOTS of relinearized images from the camera.
Since there seems to be a "knee" to the highlights in that image, and it's only the shadows that are a lot darker (the face is darker too, but the midtones in a photometrically linear image would be much darker than that), it looks to me that whatever was the project working space is re-gamma-correcting the output from LOG to something gamma corrected, like a darker print gamma correction or something of that nature. |
