Avi to more compressed AVI

[Hoagie_one]

Not sure if this question goes here or not, but here it is. I'm trying to archive a set of anime that I have, but the 26 episodes that I have are just shy of fitting on a DVD-R. I want to take teh larges episode, thats about 215 MB and compress it slightly, say to 190MB to make all the episodes fit on the Disk.

What is the easiest way to accomplish this. Do I need to compress teh video or the audio to make it fit. Curently its coded in Divx4, with 44800 stereo audio.

any thoughts on this?

It would be helpful if you specified how long your avi is and the exact audio bitrate used. Without knowing for sure I'd say that lowering the audio bitrate alone wouldn't adequately decrease the size. Get yourself an avi bitrate calculator here.

[Hoagie_one]

video length -- 0:24:19
frame size 640 X 360
Frame rate 23.98
divx 3

16:9 ratio

Audio stereo 48.000
16 bit
128 kbit\sec

file size 215 MB

Lower the audio bitrate to 96 kbps and the video bitrate to 985. You'll need to convert to Divx unless you prefer Xvid. It wouldn't hurt to lower the resolution to 512x288 either. Make sure you do a 2-pass encode and your quality loss should be minimal. I'm assuming you know how to work Virtualdub. If not, I'll be glad to help you out.

never used it but ill give it a shot right now. Thanks. I'm still real new to this

[Hoagie_one]

ok, i might need a turorial. thats alot of menus and buttons

[teegee420]

No problem. I'll work on it later tonight. Right now I'm getting my Survivor on. :P

i found a tutorial on this sight but it keeps telling me it cant decompress teh source audio. Its an AC3 souce. Any ideas?

[teegee420]

Install this.

[Hoagie_one]

its not working. I can get it to work by doing a direct stream of teh audio, but that doesnt recompress the audio at all.

You can extract and convert the AC3 audio to wav using Goldwave, just load the avi and save it. Load the avi and the wav file into Vdub (audio> wav audio) choose your audio and video compression then save avi.

Note: wav files are large uncompressed files.

All the Ac3 acm Decompressor you've just installed does is allow VirtualDub to open Ac3 files. You still have use a compression codec - mp3 is the most obvious. So use Audio>Full processing>Compression and take your pick. You will have have the required codec installed first though.

[teegee420]

feenix is correct. I should have specified that you use mp3 compression at 96kbps. If you're still having problems PM me or post here.
