Need to reduce DV-AVI file size

step 7 load it into TMPGEnc and it will spit out a nice pretty ".mpg"
step 8 ????
step 9 PROFIT!

wrong. mpg is outdated. You should only use it for contests that only accept MPEG-2.
It´s rather a distribution codec in my eyes.

You better use zarxGUI for a nice, small and fancy mp4:

(included in the AMVApp 3 beta)

It´s easy to use and gives you the best quality. Avisynth required.

Are interlacing and "noise" that big of a deal?

Yes it is. You should try to fix it first. To fix noise afterwards isn´t a good idea. You clean your footage before you edit with it. You can fix interlancing afterwards, but it´s better to deinterlance the footage first imo.

Hmm.. I peeked at the avtec guide.. I think its more useful to post a workflow, a step by step if you will. If the purpose of each step is explained, i think it will accomplish much more and much faster.

This is my workflow.

Pre-Edit

(take DVD and you need a way to copy it to your HD. )
Source DVD -> DVDDecrypter -> Vobs

(step 1 of the DVD to AVI process...)
Dgindex -> Vob to M2v (MPEG-2)
(step 2)
VdubMod (M2V->AVI)

-------------------------
Edit

I use Sony Vegas

Save As AVI using HuffyUV or some lossless format. you should
have FFDshow installed. Make the AVI without audio. Render Audio separately to its own file.
--------------------------
Post-Edit Compression

get your AVISynth script ready
(normally a one line script AVISource("file.avi")
meGUI or zarxGui -> Open the AVS script, set your framerate, choose your compression options (6 ref-frames max. any more is literally unusued, wasted time and processor. kbs determines your blockiness, ref-frames determines your fast action encoding quality. b-frames simply tell how many ref-frames in a row that provide I-frame directions can be used. Set that to less than or equal to ref-frames but close to it. )

save as RAWAVC (.264) file

(now to mux, or "mix" the .264 and the audio track-> Megui, use the mp4 muxer)

I Wasn't talking about dvd compliant Mpeg2 theres nothing wrong with an mpeg1 for distribution its better then a 7 gig uncompressed .AVI

Havent tried messing around with mp4 yet so all i san do is speak to what i know is known and proven (if a little dated)

but thanx for the info i'll look into it who knows may work better for me

mpeg1 is NOT good for distribution...it used to be, but not anymore. mpeg2 *might* be good (it all has to do with where you want to give it). Still you'll get far better quality with mp4. I'm still stuck with XViD though...too old for new tricks, heh

I'm still reading AVTech. It really is a lot of information to process at once, you learn a lot by applying it though.

There is nothing wrong with Mpeg 1 if that is all you have it makes the video small enough to be uploaded so people can watch it. yes it's older yes it sux for quality but if it is all you have to work with..... at the end of the day Did your video Get Distributed or not.

56Mb sucky looking mpeg1...........Yes
7Gb uncomressed AVI...................No

If I see a video that somone made and it's a good video I'm not going to "not watch it" just because it's an Mpeg1. Yes I may wish i had a better and smaller copy but I'd be happy just to have it at all if it's a really good video

case in point for a long time I only had a VCD of Odorikuru I still love that video.

all i'm saying is there's nothing wrong with working within your limitations until you learn to push the bounderies

Neither should be options you'd consider. That's why we have XviD and MP4.
