park on the frame you want to freeze.
in the modufy menu selct make freeze frame.
the freeze appears in the viewer. its better to cut it up than to use time remapping for this.

Steve,
Are you having this problem if you lock the Kona to house sync and leave the AJA control panle set to ext. With it set up this way you will never have to change the D-beta ref input.

This probably as something to do with the RGB to YUV conversion as FCP and the KONA are outputting YUV, so there is an RGB to YUV conversion going on.
ONe of the best CODEC’s for color fidelity is Sheer VIdeo. The RGB to YUV conversion is very accurate. You might want to examine this a bit further.
I don’t know from your post what you are outputting to. If you have capture a digital 4:4:4 then the balcks and whites should be at the full range 0-255 but if you are making downconverts or SD outputs the blacks should be at 16-235 (but the Kona will not do this for you with the HD footage. You might need to put a filter on to compensate for that.

I will add this.
HD and SD are in different color spaces so you might want to do your color correction in the 10-bit UC sequnce. Also, The firewire drive should be at least FW 800 to be able to play back that SD content.
I would also suggest that your footage will look great at DVC PRO50. Remember this was panasonics answer to D-Beta and I have output several DV50 sequences that look great. The Panasonic codecs look great when going between them and you wont miss the six lines because the SD will be letterboxed anyway. There is no doubt the DV50 will output from FW drives.

try this.
Create a sequence that is in the SD codec you want to output.
Drop your HD sequence into that sequence.
Render it and watch it in the SD codec.
Media Manage the rendered sequence including render files to firewire drive for delivery to the output shop.

Gary,
I think I qualified most of the arguements you plucked from my post in the post itself. The Panny codecs are fast becoming the workflow of choice because of the benifits they present in post production, an HD 4:2:2 worflow that does not destroy image quality with one render in FCP.
I can see Sean’s multigenerational arguement, it makes some sense. What I really would like to see is an HDCAM master played into whatever MPEG encoder the network uses compared to a DVCPRO HD master of the same show through the same encoder. It think that is where it gets a bit interesting.
The fact that you can not use HDCAM natively (although HDXDCAM can be) is another sticking point. How would the HDCAM look if it was edited and rendered natively (which you can’t even do). Most HDCAM will get further compressed when it is captured into ANY edit system.
Anyhow, not sure why you are picking on me. I’m still trying to figure out where this bit of animosity comes from. 🙂

I was refereing to the droplets available for compressor that are available on Shane’s website. They are droplets intended for High Quality Upconversion from DV source to 720P or 1080 files.

My only question is whether the film look Natress filter was fully rendered before the uprez. If you EXPORT a QT of the final sequence and then place that QT into compressor does it still take the same amount of time to render?
Compressor might be doing the filter calculation as well.
Try a test without the Natress FX and see if it is any faster.
THose are very HQ upconverters and are using the best (slowest) algorythms. It’s the old Cheap fast good deal, hard to get them all in one package. You are right, the results are stunning.

Yes,
I have used you send it. It doesn’t stay free all the time, once you get to a certainnumber of sends and a certain file size it becomes a pay deal.
The times I used it it worked great.

Sean,
I see this qualty arguement often when it comes to DVCPRO HD. DVCPRO HD is an 8 bit codec. If you come in or go out firewire it is lossless (it’s a digital stream. You are saying that the 8 bit codec that runs at a native 5.5mb/sec, needs to be bumped to a 10bit UC timeline to be rendered. I think this is overkill. You are introducing data that can not be improved upon. Rendering in the native DVCPRO HD 4:2:2 codec is clean and no where near the artifacting of HDV (which really does need to be converted to a usable for mat for post).
I know that my post to Mr. Video was strong, but it is this kind of misinformation that confuses people when making workflow choices. He stated the F900 is uncompressed and it is not.
It also depends on the finsish. For instance Walter Biscardi who does Good Eats shot on Varicam does not convert every show to a 10 bit uc sequence for CC, it stays natively in Varicam 720 until output back to tape. If you have a Kona card you are can actaully output this as an 8 or 10 bit stream, the conversion is done right there.
This is why the Panasonic codec workflow for post is so great. Small file sizes, working in the native codec with 4:2:2 color space, the hold up very well to first generation tests. If you see issues on specific shots or graphics you can render them out seperately and bring them back in. Most programs are very image based and less graphics intensive now.
For a commercial shot on Varicam maybe the choice could be make to work in Uncompressed 10 bit, because of a lot of image processing that is going to go on, that’s a great idea, but the orginal post was asking for a workflow for a documentary with many hours of footage. (this is why I described the real costs associated with shooting HDCAM over DVCPRO HD). I would not be surprised to see the HDX-900 replacing the F900 on some feature film shoots in the coming couple of years. Maybe DOP’s will go for the look of thiis camera over SONY. With a 12-bit UC stream coming off the side of it, maybe peaple will record 4:4:4 to a Viper with a tape back up with matching TC for dailies.
Sometimes people like to say “you need to do this”, “you need to do that” when it just isn’t nessesary and it doesn’t make sense and it’s based on a notion.
Good thread!
Cheers,
David
