$100 For Working DPX2CF Script at DVinfo.net

Steven A. Sandt · August 12th, 2009, 07:24 PM

Will pay $100 (cashier's check or by PayPal) to the first person to post a DPX2CF script which allows me to actually convert dpx files to Cineform files. I obviously wouldn't be resorting to this if I had been able to get help from Cineform.
I own Prospect 4K and am running it on an i7 940 3.88 ghz (overclocked) PC with 12 Gigs of RAM. I have the most recent update of Prospect 4K (also PP CS4 and Vegas 9).
I created a sequence in Combustion which is comprised of 341 frames and I rendered the sequence as dpx files. Each frame is 4K by 2K, and each is about 32 Megs. So far I have not succeeded in writing a DPX2CF script which actually converts the files from one format to the other. The following is the best I have been able to come up with:
dpx2cf c:\S1dpx\output*.dpx c:\S1cf\starfield.avi -q4 -f24 -n341
Running this script, the 341 files load, but that's all. I don't seem to be able to get it to do anything else. I don't know if the problem is the script itself, or whether I am overlooking something. I will pay the $100 for a script that works, OR, for any suggestion which allows me to find a way to convert the files using the DPX2CF utility. As soon as I succeed in transcoding the files, I will post a message to the thread which names the winner and I will provide my email address so I can arrange payment. Thanks, Steve

Your command line is correct, you are simply exhausting 32-bit memory space. We need to make this component 64-bit as it launches as many threads as there are virtual CPUs, the catch is for a 4K 16-bit per channel 4:4:4 we need about 256MB per core. 8 x 256 = 2GB = Opps.

Here is the fix

--------- cut here ----------
Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\CineForm\DShow]
"EncoderThreadsLimit"=dword:00000004
--------- cut here ----------

save as LimitCPU.reg. Double click on the .reg file. Now your 4Kx2K DPX to CineForm encodes will work.

P.S. Here is the latest DPX2CF with LimitCPU.reg file control.

!!!!!!!WE HAVE A WINNER!!!!!!
I have successfully transcoded files and DAVID NEWMAN (CTO, Cineform) is the winner!!!
The $100 should at least provide for a nice dinner. Thanks, Steve

I'll send it to your attention at the Solana Beach address. Thanks again.

That is very nice but unnecessary. We don't charge for support.

A promise is a promise. It's on its way. Thanks again.
