MeGUI: avi-file as audio source / commandline???

[Buzz Lightyear]

I've been playing with MeGUI and noticed that I can use an avi file as audio input.
If I set up the task with MeGUI it works just fine. I get an .mp4 output file with the sound of the movieclip.

My problem now is, that I'm trying to make a batchfile for a whole series of clips that I want to convert from xvid/mp3 to x264/aac. I was able to find all the necessary command lines for the batchfile in the MeGUI logfiles, except for the audio conversion (avi --> mp4). neroAacEnc.exe (naturally) doesn't accept avi as input.

Can someone please tell me what MeGUI does to convert the avi-audio directly to mp4?
All the necessary programs must be there, but I have no idea how to do that conversion manually.

Thanks!
Buzz

the audio goes thru avisynth and the output gets fed to the encoder
that's what megui actually does.

You can use avi2wav to send the WAV data to neroenc: http://forum.doom9.org/showthread.php?t=124471

eg:

wavi filename.avs - | neroAacEnc_SSE2.exe -ignorelength -he -br 64000 -if - -of filename.mp4

@mitsubishi:
Thanks. That was exactly what I was looking for.
Goto go now. Will ask some more n00b questions later....
;)

[Buzz Lightyear]

OK. If I had known before that this would be so time-consuming, I wouldn't have started at all.....
But somehow it's working now. By far not as simple or elegant as I'd wish, but anyhow.

My super complicated batch001.avs-file looks like this:
DirectShowSource("batch001.avi",fps=23.9759856527702)
#deinterlace
#crop
#resize
Undot() # Minimal Noise

My batchfile looks like this:

Since I couldn't come up with an idea how to simply feed 40+ files with very long filenames to the script, without editing the filenames in the batchfile AND make seperate .avs-files for each .avi, I renamed all the .avi's to batch001.avi, batch002.avi etc. and made corresponding .avs files.
So I can re-use the .avs files and only need to rename my avi's.
Not very elegant, I know. If someone has a better idea, you're welcome to share...

I still have a couple of questions:
- Does it slow down the audio conversion if I have Undot() in the .avs?
- Can I feed parameters (like %1) to an .avs script? That would maybe allow me to use the same script for all files.
- The audio is slightly too late. How can I fix this? I've been playing with the "-inter" parameter of mp4box, but it doesn't seem to do anything at all.

Regards
Buzz

P.S. Just in case you're wondering: No, I'm not a programmer.... ;)

- Does it slow down the audio conversion if I have Undot() in the .avs?
It shouldn't do no, because the wavi programme isn't asking for video frames.
- Can I feed parameters (like %1) to an .avs script? That would maybe allow me to use the same script for all files.No, but you can generate an avs script from within the batch script, then run it.

There's a similar script here if it helps: http://forum.doom9.org/showthread.php?p=1024780#post1024780

[Buzz Lightyear]

Heureka! It works! After all, it was easier than I'd expected in the end.
mitsubishi, you've been most helpful! Thanks!

I succeded in writing a batch file that does exactly what I wanted. It takes all .avis in the scripts folder and converts them to x264/mp4.
I've tried to add some comments to make the batch easier to understand. Maybe it's useful for some of you.
Please feel free to modify the batch to your needs. Suggestions are very welcome.

Buzz

OK. I've tweaked my batch file a little more. I've added some more avisynth filters (which should work fine with cartoon content), and I've made seperate avs scripts for audio and video processing.
There is certainly a lot more that could be done to make my batch more flexible / safe / sophisticated, but for me it works now. So I'll probably not make any more changes.
Feel free to use/change/modify the batch file to your needs.

If you want to run the whole process at IDLE priority, you shouldn't start batchenc.bat, but instead runlow.bat.

[funkydoobie]

I am posting a batch file here that I created after being inspired by the other examples in this thread. I use this file to convert captured DV video files to small, high quality MP4 (H264/AAC) files with embedded subtitles that indicate the original date/time code. The two goals are (1) to play these on a portable media player (most likely the new Creative Zen), and (2) to eventually import these into a media/video cataloging program (none seems to support mp4 well today) and--using the subtitles--quickly locate the tape and location of a given clip. I am posting this file as a means of "giving back" for all of the tips and insights I obtained from this forum, but also to solicit some feedback. Please let me know what you think! (E.g., Would you change the x264 options? Encode the audio differently? Alter the AVS script? Change the batch file?)

Here's the basic workflow; the batch file "code" appears below.

Tools Used for Batch Processing

BePipe: To "pipe" audio from the *.avi files to the Nero AAC encoder
NeroAacEnc: To encode AAC audio
x264: To encode the video
mp4box: To mux the files
(Future) MediaInfo: To write final file information to a log

Workflow

Capture DV video from tape
Use DVDate (http://paul.glagla.free.fr/dvdate_en.htm)to rename clip files and create subtitles (*.srt) with the date and timecode
Run the batch file to create mp4 files
Delete the captured DV *.avi files

Batch File Contents

Lines 001-028: DOS tips/tricks
032-061: "Printed" instructions
072-077: Variables
081-097: The main loop; calls "sub processes" for each avi file found in the directory
100-107: Confirmation of batch completion
111-119: Generate the avs file

AVS pseudo-template for "File.avi" (some lines disabled):

# 1) Store parameter in variable named "Clip"
Clip="File"
# 2) Set clip as DirectShowSource; include audio
DirectShowSource(Clip+".avi",fps=29.97002997002997002997002997003,audio=true)
# Exact frame rate is 30000/1001
# 3) Deinterlace
edeintted = last.AssumeBFF().SeparateFields().SelectEven().EEDI2(field=-1)
TDeint(order=0,edeint=edeintted)
# 4) Crop
crop( 0, 0, -2, -2)
# 5) Resize to 320x240 square pixels
Lanczos4Resize(320,240) Lanczos4 (Sharp)
# 6) Denoise
# 7) TextSub("path\filename.ext"[, charset[, fps]])
# You need textsub (vsfilter) plugin!
# TextSub(Clip+".srt", 25, 25)
# 8) ConvertToYV12
ConvertToYV12()

158-170: Use BePipe to pipe audio from *.avi file to Nero AAC encoder
174-197: Encode video using x264 (two-pass); modified Sharktooth profile for Quicktime
201-213: Generate timed text subtitle file from *.srt file
(NOTE: This is not required; you can mux in an *.srt file directly. I tried this to see if I could get mp4box's "isma" switch to work with the subtitle (see below); it didn't work)
217-239: Mux the mp4 file
243-255: (Future) Tag the mp4 file
259-272: (Future) Create info file for the mp4 file
276-305: Clean up temp files

Things I'd Still Like to Figure Out

How to set the "poster" frame of an MP4 video file (is such a thing spec compliant?)
Use a command line program (e.g., AtomicParsley (http://atomicparsley.sourceforge.net/)) to write tags to the MP4 files (in batch format)
Add subtitles to the MP4 file that are ISMA-compliant (if I add the -isma switch to mp4box, it doesn't mux in the subtitle...)
Create a log file
Create summary info files using the MediaInfo CLI
