Feed DPX sequence into meGUI via avisynth ... HOW ???

[Cooger]

I have a DPX sequence, uncompressed 10bit log, generated from the r3d files of the RED ONE camera.

Now I would like to get the footage to Bluray with as little conversions as possible, to preserve the high quality image. I would like to have a streamlined process, if possible without the use of the scenarist & co, tons of transcodes, etc.

I figured, that meGUI, with the bluray presets, for the encoding, tsmuxer, for bluray authoring, to play the dailies on PS3 or BlurayPlayer via BD-9.

What I cannot figure out, how to use avisynth to feed the dpx sequence into meGUI. I installed immaread, but I get the NoDecodeDelegateForThisFormat error, on dpx and on jpgs.

There a certain variable MAGICK_HOME variable, that should be set. No idea where, as I thought that should be set, as I thought that would be only for ImageMagick.

I have the impression that immareadseq should do somehow the trick.

I use newest avisynth/megui/tsmuxer. I downloaded Immaavs v1.30. The ImageMagick dlls are in the proper folder. I use a slipstreamed windows XP via Parallels on MacBook, latest Leopard.


Please note, that I am a producer and director, not a programmer, or encoding geek, so go easy on me. Any help appreciated.

How big are the files? Maybe you could upload a few somewhere and we can see if we could replicate the issue?

Ok, some progress...

One time at load, MeGUI complained about missing dll's. I had them in the DPX folder, but read somewhere, that its not enough to have them in the "system32" folder of windows. So I copied them there, leaving those in the DPX folder as well.

Voila, megui now displays jpeg and the dpx.

Unfortunatelly "immareadseq" is not recognized as a proper syntax....
Now, how can I load a imagesequence via Immaavs ??

Sequence reading/writing is not implemented yet in v1.30, sorry :)

immareadseq is part of the old plugin of E-Male, which can be found here: http://forum.doom9.org/showthread.php?s=&threadid=90131. That version supports sequence reading (but it has no write support).

You can also try IUF: http://forum.doom9.org/showthread.php?p=455281#post455281 If you read the readme, you will see it support sequence reading (when the images are properly named).

have you tried the QT proxies with qtinput yet? that might work, and should look the same as going through red alert but without the extra rendering step.

[edit]

ah, i see. quicktime RED codec isn't released for quicktime on PCs. i'll just keep using my scratch then.

also, i suspect this process will be far too slow for dailies, even if you used several computers for it. DVDs are probably still the way to go for now, and you can do focus checks in redcine if SD is too lo-fi (you can even get your data wrangler to do this on set with a laptop and save lots of time). remember that there's no film costs, so you'll be shooting far more than you might expect (think 4 hours of footage for a 30 sec commercial...).

@Mug Funky
Quicktime proxies use half the debayer quality. That surely is not an option, and there is in fact a HUGE difference in quality from RED Alert output. As regular SCRATCH user, you are of course off the hook, having realtime playback in at least 1k and full debayer to DPX render.

Hence, why I want to feed the dpx10bit log into avisynth.
MP4 AVC render times are in fact 3-4 fps from the feed, so it does not seem to be practical for dailies, but for day-to-day rough edits. 1:8 is good enough and it looks stunning.

Thanks for the hint about the non-existent filmcosts. I totally missed that, when I decided to shoot on the RED ONE.
