I have a video that is 1 hour and 24 minutes long and want to fit it onto on a 4.7 gig DVD. Using Sonic MyDVD, its present state would require over 6 gigs. It is 25 fps, 740 x 416, divx 5.  I had one that was 95 minutes long and it fit, so I know it can be done, but don't know how to convert this one to make it fit.  I have virtual dub & mgi video wave.  What settings do I need?  Do I need another application?

fayb,

  I am not totally familiar with Virtual Dub or MGI Video Wave, but I would suggest trying the following:

1)  Try a different compression codec.

2)  Decrese your resolution.  740 x 416 is very large.  640 x 480 would probably look just as good and would decrease your size.

  Like I said, I am not sure of the functions of your software but you should be able to make one of these modifications.  Be sure to make modifications to a copy of your origional.

Good luck, hope this helps,

Rich

You should look into lowering the bitrate of the MPEG-2 video (that goes on the DVD).

If you choose a lower bitrate, less data will be encoded each second and the total size of the MPEG-2 file will decrease.

Typical bitrate for commercial DVDs usually borders on 8 Mbps (variable bitrate). For private use, you can normally get by with much lower bitrate (3 - 5 Mbps).

Hope this helps!

Try using TMPGEnc from www.tmpgenc.net. Its very easy to use and should help.

I use TMPGEnc, but when I go to settings and video, the bit rate is set to 1150 kb/sec and is grayed out.  I can't figure out how to change it or what it should be.  It is surely lower than jamilon's comment that it should be 3-5 Mbps.  Besides, I use it for MPEG-1 to make VCD's using CDr's.  Can it be used to set up to burn DVD -r's?

Use the wizard in TMPGEnc (Ctrl+W), then choose a DVD template based on your signal standard (PAL or NTSC) and aspect ratio (4:3 or 16:9).

Once you've chosen the source file(s) to be encoded to MPEG-2, the only thing between you and a successful encode should be a click on "Other settings". Choose the bitrate of the movie (for the PAL template it seems to be 8000 kbits/s CBR by default) as described above.

I would recommend using VBR (variable bitrate) over CBR (constant bitrate). Encoding takes longer but quality goes up since the bits are allocated where they are most useful (i.e. scenes with lots of action/moving camera).

Hope this helps!

Guys, there is a free and fabulous program called DVD Shrink that compresses a file, but only to the degree it needs in order to fit a DVD.  In my experience, you can compress to about 70% without a real perceived loss of quality.  I believe the website is www.dvdshrink.org   The other benefit of this program is that it will strip out the menu and special features of a commercial DVD and creates the DVD files (VOBs) of just the film itself.  This means less compression than for the entire DVD with all the extra stuff.  You can fit a almost a two hour film on a home-brewed DVD doing this.  As you probably know, commercial DVDs are double layered and fit twice what a home-brew DVD burner can do, so you've gotta remove something, or split the movie onto two disks.

Oh also, TMPGE DVD Author is now available with a plug in for converting the audio portion to AC3 (Dolby), which is more compressed than the normal wav format.  This alone will allow you to fit a 1 hour 30 min video onto one disk.
