Best Windows OS for Hybrid, Avisynth, QTGMC?
 

I'm getting to more of the processing stage of my capture process. I know for capture that XP is often ideal, but when it comes to processing videos with AviSynth or Hybrid (mainly for QTGMC deinterlacing), what windows operating system gives the best performance in terms of video processing speed/deinterlacing?

My current machine I am choosing an OS for is a Dell OptiPlex 7010 with a Quad Core i7 3rd Gen 3.2GHz and I have Windows XP 32bit running on it right now. Currently it just is using onboard/integrated HD4000 graphics without a separate graphics card.

It has 8GB of ram installed, but I believe that can be upgrade all the way to 64GB.

So question is whether that is a decent machine for QTGMC deinterlacing and whether say windows 7 64bit would give a significant processing time boost to Avisynth/rendering over 32 bit XP. I know XP can only see something like 3.5GB of ram, but I'm also not sure how much of a factor RAM or a dedicated graphics card are when it comes to using Avisynth.

Thanks in advance for any advice!

Using 64bit Avisynth will give some speed increase, as will switching to 64bit Vapoursynth.
side note: Hybrid stopped supporting Windows 7 for quite a while
In general: The more threads are used and the higher the resolution, the more RAM you need.
Just using QTGMC on SD and HD content, 8 GB is fine.

I am wondering about this as well. I would like to utilize my main PC for editing. Windows 11 seems to have abandoned AVI entirely. What programme with a GUI would you recommend using Avisynth with? Thanks

Personally, I use Hybrid (but I'm obviously biased), but avspmod is probably easier for editing scripts on your own.

Thanks for the fast response and your awesome software! What OS do you use personally when using hybrid?

I use Windows 11 and mainly develop Hybrid on Windows 11.

Ahh ok it must be my setup that doesn't like windows 11. I'm capturing with a USB 2.0N on XP. All my AVI files will not play properly on windows 11. I was made aware the card would only work with XP but thought that was the capture side.

That sounds more like you are lacking a decoder for your file.
Got no problem here playing avi files.
Depending on the format you use, using a player like MPC-HC or VLC might work, even if the system has no decoders, since they come with their own decoders.

^ This.

What are you capturing to? You should be using Huffyuv -- and not MT, 64, hacked CCE, etc. Just plain/official Huffyuv.

VLC gives a broken or missing index warning and then usually only play a few seconds. MPC will not give a warning and play the same. I have installed codecs but still have the same issue. I'm going to install windows 7 this evening to see how that plays out. I get the same errors with or without multi segment capture enabled. If I try to edit files it will only edit the portion the players allow me to play.

Thanks for your time

Thanks. I'm capturing with lagarith. I'll change to Huffyuv.

Lagarith plays fine here on Windows 11 (in MPC-HC), do the attached samples play fine for you?

Lagarith has a known byte error that was never fixed.

See this: https://www.digitalFAQ.com/forum/vid...-lagarith.html

I rarely see it, but some folks have had worse luck in the past. Most just swapped back to Huffyuv, since Lagarith was just a fork of Huffyuv anyway. The Lagarith fork has more compression, but at cost of more CPU use. And some colorspace wants (not really needs).

Yes, these files play fine. I wonder why mine don't, I downloaded the codecs from the official site.

Thank you very much. I tried Huffyuv with the same results before Lagarith a few weeks back. My wrongdoing is I was using the multi-thread variant and another modded version I downloaded here. I have switched to official now which is working out of the box. Great stuff!
