compressing videos

[Vic The Jedi]

hey guys

ive just got a all in wonder 9700 and have captured a family video with the intent on sending it, on cd, to relatives in the US

as im sure you can guess, the files are huge 1.2gig and 2.5 gig mpgs

i wanna get these onto a normal 700 or 800 meg cd

Please could you give me some advice on how to encode/convert/compress, whatever, needs to be done to do this

any help will be most appreciated

Thanx for your time

Do you desire to create CDs that playback only on computers, or on standalone DVD players (hooked up to televisions)?

[Vic The Jedi]

i think theyll be playin on a PC but knowing how to do both would be handy

(You can ignore Step #1, since you've already created your initial MPEG files)

From Ripping through VCD (by me)

1) Rip DVD with DVDDecrypter

2) Convert to .AVI using Flask or MPEGMediator
A) Using DivX v.3.11 codec (Fast Motion 910kbps, keyframe every 10 seconds) or other DivX codec, or Xvid codec, or 3IVX codec
B) Using PCM (uncompressed) audio at 48,000Hz (Maintains synchronization of audio and video)

3) Load .AVI into VirtualDub
A) Set "Video" to "Direct Stream Copying"
B) Set "Audio" to "Full Processing Mode"
C) Under "Audio", click on "Conversion", select "44,100Hz" (or 48,000Hz, if this doesn't present a playback problem for you)
D) Under "Audio", click on "Compression" select "MP3", "44,100Hz" (or 48,000Hz), "96Kbps" (or higher)
E) Save revised .AVI with new filename

Then, to create a VCD:

1) Load .AVI file into TMPGEnc
2) Set to "System Video and Audio" (lower right side)
3) Click on "Setting" radio button
4) Click on "System" tab, change mode to "MPEG1-VideoCD" (from default of "MPEG1")
5) Click on "Advanced" tab, change "Video arrange method" to "Center (Custom Size"), change dimensions to 352x288 or 352x240
6) Change "Source aspect ratio" to either "4:3 525 line (NTSC 704x480)", "4:3 525 line (NTSC)", or "16:9 525 line (NTSC)" - If you're in the PAL world choose either of the two similar PAL settings instead
7) Under the "Video" tab, change the dimensions to 352x288 or 352x240 (Note: "Video" tab mode of "MPEG1" is okay) - for highest quality set "Motion Search Precision" to "Highest Quality". Change the "Aspect Ratio" to match, as closely as possible, the "Source Aspect Ratio" you set under the "Advanced" tab.
8) Change "Rate Control Mode" to "Automatic VBR (CQ_VBR)"
9) Under the "Audio" tab, set to 44,100 224Kbps
10) Press "Start"

(Or, instead of the steps 1)-10) above, you could attempt to use TMPGEnc's VCD "wizard"/template)

Note that if your video runs longer than 60 minutes, you'll have to subsequently split your VCD-MPG file in two. This too can be easily and precisely accomplished using TMPGEnc. Under the "Files" dropdown menu, click on "MPEG Tools" and select the "Merge & Cut" tab. Once again, make sure to change the mode to "MPEG1-Video CD". Load your file and enter a new (.MPG) name in the "Output file" box. Then doubleclick on the ORIGINAL file's name in the window, which will bring you to the cutting area. Select your desired start and end points for the first half, click on "Okay" which will bring you back to the first window and generate (in a sequence of three automated steps) the first new file. To create the second new file, repeat the steps starting with "Then doubleclick on the ORIGINAL..." (be extra patient with the second half, as the program has to do more seeking to establish the beginning of the new file).

Use a burning program, such as NERO to burn your CD-R or R/W CD as a VCD (DON'T ask NERO to format the file as a VCD, since you've already accomplished this!)

woah

thanx man

[setarip]

"thanx man"

My pleasure ;>}

You say thes files are already mpg? If mpg is the desired end result don't encode them as avi first. Try to use Tmpgenc to transcode lowering the bitrate. Is the audio a wav. If so encoding it as mp2 will lower the file size drasticly with out a re-encode for the smaller of the two files. The larger file can be cut down to multiple cd's, probably 2. Every time a filed is re-encoded quality is degraded. If avi is the intended end result then flask works well and usually you will end up with the audio as a mp3.

i'm kinda having the same problem. i just made a minute and a half video (mpg format) for our club's site and the thing is...it's 17mb. i was hoping to convert it to another file or whatever to make it atleast 50% less it's original file size.

my friend's been telling me about tmpeg but i don't have any idea where to get that or what that is. can anybody educate me? thanks!

to PiNaY_AnGeL:

The steps that are to be taken to encode a small sized movie
for the use with a website are slightly different.....

you have to decide what format of the three most widespread
you want to use....

1. Windows media player compliant format *.wma or *.asf
this is the most widespread format since windows media player
comes with every Windows OS

2. Real player or real one format *.rm the second frequent
used format....

3.Quicktime format *.mov Apple users can view this format with
no additional software since quicktime is an apple program
windows user can also view this format but they must have quicktime also installed.....or a compliant player.....

all three of these formats are able to produce good moviefiles for internet website use , that are a lot smaller than mpg files....

make your decision and then come back!!
