mpeg files are reading 2 gigs in size once in tmpgenc????

[london]

Merry crimbo all that enter........Right i have this problem with tmpgenc.......i load up my 2.5 version, in the project wizard i select pal.....then in step 2 i browse to an mpeg (normal 700 meg or so mpeg)...once its in there both sound and audio i then go to step 4.....once in step 4 i un select auto and try and make the file size around 50 megs bigger then the original file...i'd say 80 percent of the mpegs i have i cant lower then 2 gigs in size....any ideas?

hehe you got lucky if it's ONLY 2 GB cause if it's a movie it's supposed to go around 3.8 - 4.5 maybe even sometimes more than a dvd-r can take and than you have to use dvdshrink... it's supposed to be that big..
if you have an original dvd movie enter it to one of your drives and look at the size of that thing! I assure yu it will be even more than 5 gigs..

Ignore pupik, he is talking a load of rubbish.

The size of an mpeg file is determined by bitrate and playing time, nothing else. You could have a 2 hour movie on one CD, though it would look pretty awful.

Are you sure your source files are mpegs and not avi's. I ask as the symtoms you describe sound very much like what you get when you encode avi's that contain VBR audio. TmpGenc has a known problem with this. Try searching the forum for more details.

for real they are mpegs

for real they are mpegs

Then why do you want to re-encode them. If they are VCD and 25fps PAL or 29.97fps NTSC, the video is already DVD compliant. You just need to re-sample the audio to 48khz.

If they are 23.976fps NTSC(film) then they will need to be re-encoded to be DVD compliant, but some quality will be lost.

As for Tmpgenc, try setting things manually (skip the wizard).

Click load and select a suitable template, then click load again and select unlock.mcf from the extras folders. Then click settings and set everything manually, most things should be OK except bitrate and maybe a few others depending on the template you selected.

Well, the source files are 700Mb Mpegs which means probably (S)VCD, so increasing the size will not increase the quality! Still not sure why he wants to re-encode

[london]

no no no im not increasing the file size, i cant get it down to the correct file size, only 2 gigs!!!

[london]

in the reason why i wanna re incode is because i wanna make them in to dvd mpegs so i can then put the files in to dvd authoer tmpgnc and make menus and vobs etc.but untill i do that dvd auther will not reconise the mpegs

Try opening the mpegs in bitrate viewer and checking the properties. If they are VCD, then you do not need to re-encode (as mentioned earlier), only the audio needs to be changed. If they are SVCD, then you still may be able to get away without re-encoding by using SVCD2DVDMPG. This produces non compliant video but in such a way that TmpGenc DVD Author will accept them. How your DVD player handles this is anybodies guess, but many are fine with it.

Check the WHAT IS section with your mpeg specs to determine if they are VCD or SVCD.
