Shrinking AVI's

[wooduck]

Hi
Can someone help with my problem with a large AVI file.
(the file is titled blahblah xvid.avi)

I have tried to convert from AVI to MPEG with TMPGenc AVI to MPG
and also santa, I get the message too big etc in TMPG,and santa bombs out after getting me all exited thinking it's going to work.!!

I have split the AVI file and I would like to reduce the size of it (them) and then rejoin.

I have seen a lot of forum space talking about doing this but I have looked at so many I don't know whether I am Arthur or Martha at the moment.

Firstly I don't know which of the programs talked about to use, and secondly will any editing effect the audio.? I haven't a clue about muxing and I don't really want to go that deep.

Is there a straight forward method of doing this.

Many thanks

Wooduck

i'd stick with tmpgenc. first of all what type of disc do you want to create? VCD? DVD?. if you want mpg-1(VCD) you can still encode in tmpgenc and ignore the "too large" message, you can just "cut" the file after tmpgenc encodes it using "mpeg tools" and merge/cut feature.

Open the original AVI file in "VirtualDubMod" ("File" > "Open Video File"). Then go to "File" > "File Information" and post everything that is listed in both the video and audio sections of the dialog box, or post a screenshot of the information.

Chances are that if it's a decently made XviD-compressed .AVI, the only further compression that could be done (without totally ruining video quality) would be to convert the (typical) .AC3 audiostream to .MP3.

Converting an XviD-compressed (or DivX-compressed) .AVI to ANY MPEG-1 or MPEG-2 format will always result in a FAR LARGER filesize than the filesize of the .AVI...

Thank you all for replying.
Ormonde I have placed the info below. When I opened the file in virtualdub, it did come up with a message saying the audio bitrate needed to be changed, and virtualdub would take care of the header or something like that.
It is an excellent quality .avi, great picture,and sound when I play it in Power DVD.

not always, i have in the past converted many divx-compressed .avi files to mpeg-1 using tmpgenc that resulted in an approximate 150-200 MB size reduction.....(from app.700MB).

Would I be incorrect in speculating that, in order to accomplish this, you reduced the resolution significantly (and, perhaps, the butrate as well)?

A quote from your initial post:

"I have tried to convert from AVI to MPEG with TMPGenc AVI to MPG"

You have not stated explicitly what you are seeking to achieve with your AVI file(s). Is it your desire to "Convert" the file to a DVD-related file structure for the purpose of viewing on a conventional standalone player? You did state in your 2nd post: "It is an excellent quality .avi, great picture,and sound when I play it in Power DVD.", so I take it that the AVI plays fine on your PC. What is your purpose in "Spliting" the file?

i can't say it is an entirely incorrect statement, just that a few exceptions do exist. of course it was "rare" when such a thing would happen....(and only occured for mpeg-1).

Sorry, I clean forgot that I didn't say what I was trying to do.

I am trying to get the original 700+mb AVI file onto a DVD-.

I haven't had this problem before, and I can't remember using a xvid.avi file. (but maybe people don't title all .avi files with the divx or xvid so I wouldn't know.)
I suppose converting it to a different compression system is out of the question. (am I being stupid?)
It's a particularly good movie and, I would like to do it but if it's going to lose too much I will just have to be happy watching it on a computer monitor.

Thanks for your trouble ormonde. Look forward to your reply.
I think we have 9 or 12 hrs time difference.

Simply use VirtualDubMOD (Different than standard VirtualDub), to save the audio stream as an Uncompressed PCM (WAV) file as follows:
Using VirtualDubMOD to Convert "VBR" .MP3 to Uncompressed .WAV

1) Load the .AVI file into VirtualDubMOD (a different program than the standard VirtualDub)

2) From the "Video" dropdown menu, select "Direct Stream Copy"

3) From the "Streams" dropdown menu, select "Stream List" - and rightclick on the audio stream, then select "Full Processing Mode" - then click on "OK". Rightclick on the audiostream again, then select "Compression" and make certain it is set to "No compression (PCM)"

4) From the "File" dropdown menu, save the .AVI with a new filename

Then:

One set of procedures (other posters may/probably will suggest alternative methods) would be:

1) Use "TMPGEnc" (or "TMPGEncPlus") to convert the .AVI (DivX-compressed or otherwise) to compliant MPEG2-for-DVD format - Use "TMPGEnc's" DVD wizard/template to accomplish this

2) Use "TMPGEnc DVD Author" (a different program than "TMPGEnc") to easily create the required additional DVD files and structure (and chapters and a menu, if you wish)


**If the combined filesize of the DVD "package" written to your hard drive is greater than 4.37Gb, use DVD Shrink (or similar) to compress


If your O/S is either Win2000 or WinXP, TMPGEnc DVD Author can also burn your DVD. Otherwise, use NERO to burn in "DVD-Video" mode
(As an alternative to "TMPGEnc DVD Author", you could use "DVDLab")


Let us know of your success ;>}

Thanks Setarip.
I will try that and post what happens.
Just one question, when you say "Load the .avi file" do you mean the full file or the 2 parts one at a time. (I have both lots)
Thanks

"Just one question, when you say "Load the .avi file" do you mean the full file or the 2 parts one at a time."

Preferably, the "Uncut" version.
