MeGUI: General Questions and Troubleshooting Thread

OK, I didn't realize that megui would update all the avisynth dlls on it's own.

I can't get DirectShowSource to work with mkv/mp4/x264 source files to encode to xvid, I wonder if that might work for me.

It won't. I modified the autoupdate.xml to force the update.

I have two OTA HD recordings that I wish to encode using MeGUI but for some reason the source can not be detected using the analyze in the AviSynth Script Creator. What can I post so that someone can help me figure out what deinterlace settings to use?

EDIT: Forgot to mention that these files are 720p @ 59.94fps.

Assuming it isn't mixed, just find a clip with lots of motion & step through it using something like VDub (anything that will show the content of each frame without applying lots of processing to it first), a frame at a time. Look for frames which have combing around movement & for 20 or so consecutive frames post whether they show any significant interlacing or seem to be progressive.

The resulting pattern tells you all you need to know in most cases (excluding rare horrid messes).

For example, if every frame is interlaced, you need to deinterlace; yadif is nice imho.

OTOH if you had a pattern of iipppiippp... this would be typical for film that had been hard telecined to ntsc frame rates & so would need ivtc

I'm not sure what patterns are typical for 720p, as it's been a while since I touched any. Iirc I think I've seen iiiipppppp, where every other frame is a duplicate, so keep an eye out for duplicate frames too & report on that.

Or just put a short clip up on some file sharing site.

How much of a clip do you need and where is a good place to host the file?

See http://forum.doom9.org/showthread.php?t=130290

A few suitable seconds would do, but 10 to 30s would be nice. Just make sure it's from a well lit section with lots of motion - not inside a dungeon with the lights out.

I'll post something when I get off of work. Since the files in question are Lost and Eli Stone I doubt there will be alot of motion.

Here is a sample 720p OTA HD MPEG2 clip. Using the analyze function of MeGUI's AviSynth Creator I get source not detected. Could someone analyze the source and tell me how to convert the 59.94 framerate to 23.976? Thanks.

rack4: no interlacing, just lots of duplicated frames. The source you want to recover is the sequence abcdef... The material you have presents as aabbbccdddeefff...

So, the pattern repeats with a length of five. From each such block of five frames you want to throw three away.

In Megui>AVISynthScriptCreator>Filters, set source as M-in-5 Decimation Required & set M as 3. You can now set the 'deinterlace option' to Tritical Decimate.

If you look at the resulting AVISynthScript you should see the line:
TDecimate(cycleR=3)
Just before any cropping or resizing is done. That's doing the job for you. Preview the script to make sure before encoding.

there is one weird stretch in the clip, from frames 396-408, it's typical LOST, they always seem to have some weird stretches that just don't make any sense. I've been using TDecimate(CycleR=3) for all the new episodes this year and for the most part they have looked pretty good, we've (Plugh and I) discussed these weird cadences before.

/gets files back out of bin

Oh yes, so there is. Ignorable I assume, but still, it would be interesting to know what processing led to that.

Hi all, I recently got a movie in MKV and I am trying to re-encode it in divx format... I start the encode and everything is running fine... I have a quad core, and I set it to 3 threads but it only uses 50% CPU... anyways, thats not my problem... 20 mins into an encode my monitor goes blank and I cant restore it... I tried turning screensaver off, and nothing works... computer is still on, I think it may have crashed or something... tried multiple times, still nothing... No overheating, so I doubt its any hardware problems... This is since the newest version... any help would be appreciated

Hi everyone, im trying to convert some videos with Megui but it doesnt convert the audio when nero audio codec is selected, says "error".

I remember that nero audio encoder doesnt get downloaded in the updates, ive instaled nero on:

C:\Programas\megui\tools\ndaac

can anyone help?
Thanks

Do you have the path set in MeGUI setting?

[ricardo.santos]

still not working...
C:\Programas\megui\tools\ndaac\neroAacEnc_SSE

Try using the non SSE version. Also look at the log and see what the error is.

Yeah, I noticed this bug a while back. MeGUI does not work with the optimized NeroAacEnc, for some odd reason. Just forgot to report
