DVDx 2.2 - wie kann ich bei MPEG-Konvertierun die Output-Grösse verringern?

DVDx 2.2 - how can I reduce the output for MPEG-Konvertierun size?



Frage von andre aus wien:
Dezember 2005

Hello,

I wish with DVDx 2.2 of VOB / IFO (SonyDVD camcorder files to convert approximately 120 GB of source data) to MPEG1 or MPEG2 and produce where possible using a space-saving files (it comes to conference recordings, in which the image quality is not that important, but I do as few disk burn for a complete conference documentation would like - after all, I need the whole for all 100 participants).

Now I wanted to approach with the "optimal point", while I, the individual parameters of the output settings fluctuate and look where are the quality and the volume of data generated still bearable.

In the output settings of DVDx, although I can) set the film format (Export Settings resolution that created MPEGs are of image size and Resolutionauch always different, but unfortunately still the same size. When I contrast, eg alter the video bit rate, does this ALREADY on the Size of the created MPEG files. Must it be so, or I'm doing something wrong?

After 3 hours Internet search and trial and error, I am thankful for every tip

Andre

You use a "Sandschippchen" and want to build the Church of Our Lady ...

The footprint you can on the video bitrate (up to 9.8 Mbps), the image size (720x576, 704x576, 352x576, 352x288), the type of video compression (MPEG1, MPEG2), an audio compression (uncompressed, MPEG-1 Layer 2, Dolby Digital AC3) and the audio bitrate for the compressed audio formats to control. The key data to give you before the DVD standard. http://www.dvddemystified.com/dvdfaq.html

I would have to squeeze as much material (run?) On a video DVD, I would begin videomäßig with MPEG1 and 352x288 to see if the eye causes cancer. With the sound I would be somewhere in the direction of Mono, or MPEG compression p.38 kbps kbps AC3 p.64 any farther. Problems can look at international participants from NTSC countries give. "

Another, better approach is IMHO some WMV movies from the sessions to create and copy a (multiple) data DVDs. The video compression codec for Windows Media 9 is quite effective. Ggf. can be made synonymous thematically separate data DVDs. The image size can be rel. free. Would look to the competitors on their PCs.

Good luck

Hi Stefan,

Thanks for the quick response,

the with the "Sandschippchen" True, but I thought it comes to mass production of a basically "simple" process (ie, more of a brick warehouse,) as an elaborate church. Do you think I have DVDx with the wrong tool?

In detail: the setting of bit rate, compression, etc. I realize that (yes works synonymous), since coming out synonymous different file sizes. But if I keep these parameters constant and varied as only the image size, always comes out the same file size. Am I Doing Something Wrong? DVDx is this a bug? Or must it be?

Example:

Source file VOB 1 GB
Target format MPEG1, video bit rate 650
Target file 246 MB
And although in

Image size 160x128
Image size 320x256
Image size 640x512

For your other tip: MWV movies - okay, that I try out (then synonymous with other countries, I would have no problem - right?). Which conversion program because I come s.Einfachsten of VOB / IFO to WMV?

thanks you

andre








Antwort von Stefan:

DVDx is simplified - - a user interface for the Recompress of DVD material in another format. Most other formats are not DVD format (image size incorrect for DVD for DVD Kompession wrong ...), but "backup solutions for the DVD copying shrewd friend".

If you are providing constant bit rate video always comes out half an equal file, no preference whether you änderst the image size. You verbrätst with a very small number of bits Extreme Picture halt it. DVDx makes the stubborn right. You can with a smaller picture, the video bitrate accordingly runterfahren and thus reduce the file size.

But thou shalt s.deine task rangehen fundamentally so.

What source material have you as MPEG2 on DVD? How long is a total of 32 h for example? How can it be divided into eg 45 minutes per piece with a lecture?

What is the target format of the question? Maximum tolerable number of disks? Fits video DVD? Or movies to play on the calculator? It is important to note that those who can play as / is filmed with PAL as what happens with international guests with NTSC playback - it works yet or video DVD movies on your PC better?

WMV you can do with Windows Movie Maker, if you still need to cut, or directly with the Windows Media Encoder. Both Bill away ;-)

Good luck

Hi Stefan,

thank you - now I realize why it does not change the Deteigrösse.

"But thou shalt s.deine task rangehen fundamentally so.
I take this ball and now time to look forward, if you give me any further hints (though I do not wish to charge too much - I have been so helpful that I know I've been looking at DVDx for something that is not at may be).

> What source material have you as MPEG2 on DVD?

VOB and IFO (which is not inside the VOB I know)

> How long has it been a total of 32 h for example? How can it be divided into eg 45 minutes per piece with a lecture?

Because the DVD camcorder, there are about 40 directories, which I have each herunterkopiert of a recorded disc (each about 1 GB, which corresponds to 30 min). Synonymous with a lecture can go over multiple directories.

I did NOT cut in front, do something about it, or distribute films together - the work I do not. It seems to me not synonymous is important to create a super DVD edition of the event, but simply a full documentation for all those who were here and all the ressources like this would have been.

> What is the target format of the question?

One that is as widely as possible and without any reloading of drivers and codecs can be played on all PCs as possible. It is not necessary for running the result on DVD players. That is why I came to simple MPEG1 (because DivX will be loaded on some machines must be bigger and MPEG2 files produced).

> Max tolerable number of disks?

So more than 2 for the whole event would be in my copy too much. I must then yes, it has a circulation of about 100 pieces produced and that would then be 200 DVDs - that's my ceiling (otherwise let it be me - what I'm doing is "free choice", not "mandatory").

> Adjust video DVD? Or movies to play on the calculator?

Movies tend to play s.PC

> WMV you can do with Windows Movie Maker, if you still need to cut, or directly with the Windows Media Encoder. Both Bill away

okay, I'll pursue the times - thank you!

So you come to about 20 hours of video. The VCD format (352 × 288 pixels, 25 fps) you would need for three (or more precisely 2.75) blanks of the type DVD-5. If you rotate the avatar or something s.der quality screw, you could compress the images synonymous determine two blanks. For a stationary camera angle that should not be sooo difficult.
