GOUT image stabilization - Released — Page 42

@Chewtobacca

It's nice that the PAL ROTJ master was better, but some of us aren't in a position to obtain the PAL DVD and we have to "make do" with the NTSC release.  As such, has anyone even tried to take a crack at modifying this script for the NTSC version?

Out of curiousity what is the average processing time for this script on a quadcore computer?

I'm currently looking at 32 hours.  I'm using an AMD Athlon II quadcore, 2.9 GHz, with 4GB RAM.  I also have an ATI Radeon 5770 graphics card which, under Windows 7, takes advantage of DirectCompute 11 (i.e., the graphics card takes on some of the processing tasks), which is supposed to be beneficial for such things as encoding.

Prior to this system, however, I was looking at a 6-7 day encode.

Edit: Oops, looks like I was only looking at the time for the first pass.  I guess that means I'm really looking at 64 hours :(

Tip - render to an lossless AVI first (if you have the space), then use that as your source for your multipass encode.

Thanks for the tip Moth3r.  I am following Oldschooljedi's instructions, so at what point in the process would I create a lossless AVI?  And how would that affect following the rest of the instructions as given?

After you've created and saved the script, open the AVS file with VirtualDub. Using a lossless codec for video compression - I recommend Lagarith - save the video as an AVI file. This will take hours but you only have to do it once.

Now run your MPEG-2 encoder, and select this AVI file as your source. You'll find it speeds along for both passes, because the heavy AviSynth processing has already been done, the CPU is only being used for decoding/encoding.

Cool, thank you.  I'll definitely try this out when doing ESB.

BTW, HCenc is currently on its second pass and is giving me the following error message: "WARNING, small source mismatch found in pass 2, count: 40181 frames."  I hate to ask (as I think I already know the answer), but is that bad?

corellian77, check "Reload Avisynth" or "use lossless intermediate file" under Settings 3. It should help.

rockin, did you install avisynth for 64-bit Windows?  I had trouble loading the AVS script too before upgrading.  From what I understand, you need to install the regular avisynth first, then install the upgrade.

That being said, you can see from my posts above that I'm not exactly having the best luck myself, so take my posts for what they're worth :)  I tried these just for the heck of it, but it looks like I might be better off waiting on dark_jedi's versions.

Thanks for the help guys.  Like I said earlier, I just followed Oldschooljedi's tutorial, adding filters here and there when HCenc obviously was looking for something that wasn't in my plugins folder yet.  I've only got a few hours left before the encode is done, so I'll just wait to see what it churns out.

Aside from OSJ's tutorial, is there another, perhaps more current, set of instructions for applying gforce's script to the GOUT?  I'm pretty green when it comes to programs like avisynth, virtualdub, and so on, and a nice step-by-step tutorial would be grand for me and others of my kind (i.e., encoding noobs).

Why?  Can't you ship the PAL disc?  It wouldn't cost that much.  I'm not sure why that was addressed to me, but, to answer your question, to the best of my knowledge no one has modified the script to work with the NTSC version.

That's what I wanted to know, thanks.

And to decode between the lines of what I said: some of us only have the NTSC version and don't want to spend money on a DVD we otherwise can't use.  Hope that's clearer. :)

Quick question: I downloaded both VirtualDub and Lagarith.  I installed the Lagarith codec (I believe, anyway... it created a .dll file in a Windows sub-directory).  I then installed and ran Vdub, and started the conversion into a lossless AVI as you suggested.  My question is, is Vdub using Lagarith automatically?  Or did I have to instruct it to use it somehow?

Thanks Chewtobacca.  So instead of telling VDub to use Lagarith, it was left defaulted to "Uncompressed RGB/YCbCr."  Is this better/worse than having used the lagarith codec?  "Uncompressed" sounds like it would be ideal, no?  (btw, the file size looks like it'll be around the 160-170GB mark by the time it's done).

Uncompressed = no compression, huge files.

Lagarith = lossless compression, identical in quality, but smaller files (guessing around 60-80GB).

Thanks for the info Moth3r.
