    Hmm, that's odd. If it says mencoder is missing, it's not the step where it starts encoding the h264 file, it's the step where it does the lossless file before encoding it to h264. If you uncheck "Add pre-rendering job" in the encoder config tab, it will skip that step and encode it directly using h264 without needing to use mencoder so that can be a temporary fix.

    Can you tell what OS you're using, if it's a 32 or 64 bit one, what video profile you used and confirm that you have a C: drive(just in case but I doubt that would cause problems either way)?
    Also, try to delete the sandbox folder and start the exe again just to make sure it's not trying to use an old sandbox folder. It doesn't need a sandbox folder, it will create it's own unlike the previous version of MeguIVit which had to replace the one from MeguIV.

    I'm using Windows 7 64 bit, and the 480p 60fps Quality+3 slightly modified. I disabled pre-rendering and got "x264.exe' is missing", so with the same sort of thing happening twice, I figured that "shame on me", there has to be something wrong at my end. I deleted the sandbox folder as you said and got a different error at another point, deleted it again and got an error at startup... Long story short, Panda Free Antivirus silently screws it an all sorts of ways even with all notification settings enabled, and behavioural options disabled.
    Funny thing is that I usually have my antivirus disabled, especially when encoding, so maybe the same thing would actually happen here with the old MeguIVit.

    The antivirus is a likely candidate for blocking those that I didn't think about, they don't like "invisible" exe being executed without the user really knowing about it.

    So far I've had luck with MeguIVit 480p 60fps Detail +2 as my go-to encode setting, but I'm having trouble with some videos with a "halo-effect". I've read some posts in this thread by Vitreous how edgeclean can help, but the encodes are failing. I tried encoding a second time to get the specific error, but I didn't get a dialogue box this time. The audio and video went through the encoding process, but there was a process that failed to start.

    If you go in the queue tab, you can see all the steps and if one failed or not.

    I just started an encode with your preset and edgeclean checked to test and it's at the step where edgeclean is applied(that would be the first video step) and it hasn't failed or made any error so far. I'll let it run to see how it goes, but it looks fine so far and if you say the video step completed, edgeclean shouldn't affect any other step so that's odd.

    Maybe there's other settings you're using or not using that are affecting it, details on everything you changed from default or screenshots of the settings tab would be helpful in trying to replicate the problem.

    Edit: I may have spoken too soon, looks like the extra processing from edgeclean makes mencoder crash after a few minutes every time on my test computer meaning you likely can't use the default Threading options, you'd either have to increase the cache memory(which can be tricky, I'm pretty sure vitreous talked about it somewhere in here) and/or reduce the amount of threads.

    Also, when you get an encode that crashes, it's a good idea to clear the queue first before starting a new encode since it will likely try to resume the previous one when you launch the new one and skip the step that failed. Deleting the sandbox folder also achieve the same thing.

    You can also right click the failed step in the queue tab, change it's status to waited and retry it if you want to keep the exact same settings, but retry it for some reason(there's a good chance it will fail again though since nothing changed, depending on the problem).

    Trying to do some things with Avidemux. What filter should I use from this list to get high quality deinterlacing like MeguIVit does?

    None of them. Meguivit uses qtgmc which is the quick version of tgmc with a few other stuff around it and nothing native to avidemux comes close to it in term of quality.

    You'd have to use an avisynth script with qtgmc and load that in avidemux.

    Okay thank you SamKook, I've been googling and it seems really complicated to do because of obscure dependencies and whatnot. Also the information I found might be outdated, so I'd appreciate any help doing that.

    First, download one of the avisynth 2.6.1 version there(the difference are the dependencies since they're testing switching to new compilers): https://sourceforge.net/projects/av..._Alpha_Releases/AVS 2.6.1 Alpha 1 [20160517]/

    As for the dependencies, read the text below the download, it will explain all of them.

    Then install the qtgmc plugin from here(there's a version 3.33 later in the thread that wasn't officially released kind of, doesn't change much): http://forum.doom9.org/showthread.php?t=156028

    Last thing left to do is to create a .avs file that loads your video and audio source and apply the qtgmc filter and load that with avidemux(assuming you still have other stuff to do with the video, if not you can use any other encoder you want) instead of your video. The avisynth wiki and the qtgmc readme are your friends here.

    Edit: Actually, you might need to load the script with avsproxy to load it in avidemux. It's not something I've done often so I don't quite remember but googling how to open an avisynth script with avidemux will tell you how.
