File Size Management

Okay, so everyone helped me figure out how to get from APP 1 /w Lagarith through AVISynth to TMPGEnc to an .mpg file. The movie is 7 minutes 20 seconds and 300 MB. (anime video & live-recorded audio dubbing )

I'm trying to get it smaller, and would like advice on what to tweak. <100 MB would be ideal, and I'm willing to sacrifice quality to reach that. I haven't tried compressing audio yet, would that make a large difference? I could go look up in the guides which compression method would be best, but it's so much easier to play the noob and ask for help ^_^. Feel free to tell me to go figure it out on my own.

My main questions are what audio compression method to use, and how to manage the dimensions to end up with 320x240 (a version not for animemusicvideos.org). What I did appears to have reduced the resolution, but the end result stays 640x480. Do I need a new TMPGEnc profile?

Export settings from APP 1:
Microsoft AVI
Lagarith - RGB (default)
Millions of Colors
320/240
29.97 fps
D1/DV NTSC (0.9)
Interlaced, Lower Field First, Optimize Stills

Audio: Uncompressed, 32000 Hz, 16 bit, stereo, 1 frame interleave

AVISynth: Just DirectShowSource("file")

TMPGEnc, using Scintilla's Otaku Video general submission TMPGEnc profile:
Interlace, Bottom field first (field B)
4:3 525 line NTSC 704x480 or 4:3 display
film movie
640x480

Thanks to anyone with the patience to read my whole noobish post ^_^.

Yes. A really big one. Uncompressed songs are 3mins =~ 30MB (at 44khz, you have 32khz so your uncompressed file is smaller). mp3 codecs like LAME compress the 3min file to ~ 1,4MB

Has it really to be an old sloppy mpg file?

Okay, thanks for the tip.

If not .mpg, what would you suggest?

x264 with mp4

It´s the master of all codecs (for me at least). It is easy to get your well cleaned up DVD footage - amv to 10MB per 1min or less (with audio).

Here stands everything you need to work or know:

You can also try without graphical user interface (GUI); with simpel .bat scripts:

The GUI includes AAC+ audio compression. If you use the script method, you need the AAC+ encoder too for the audio stream:

Wow, that looks great, I think I'll try it. Thanks!

And on a side note, I would like to apologize to Scintilla, because since posting I read his APP guide and found that he already listed all the settings i should use >_<.

Hmm, I installed AMVapp, and I don't seem to find Zarx264gui in there... am I missing something?

Just making sure, did you get the right version? (AMVApp 3.0 Beta)
