mpeg to iso?

[KLouis22]

I have a H/W and S/W pkg for videotape to HD that makes mpeg2 clips. Don't like the other enclosed S/W to author DVD. Can the mpeg clips be compiled for an ISO file?
I have different iso-type prgrs, dvddecr, dshrnk, nero, imgbrn. Any of these I would rather use even if have to output to file or ifo.

Why would you want an ISO file? They are handy for archiving, or making multiple copies, but that's about it. Of the programs mentioned, ImgBurn can archive to ISO and maybe Nero, but I wouldn't trust it for that.

Your question doesn't make sense.

It sounds a lot like this:
"Instead of wrapping my hamburger with foil, can I bronze it?"
I guess, yeah, sure, but why?

You can't actually eat it now.
Just like the DVD player would not actually play the DVD anymore.

Ok then, how to make a burnable-to-DVD file from a bunch of mpeg2 clips?

I mentioned iso file because I like it for most DVD to HD ripping and then burning with imgburn or dvddecryp. It's easier/simpler than dealing with the Video_TS folder contents resulting from a rip to 'file'. Making the iso file gives a nice, neat ready-to-burn pkg with all decisions and options already done within that iso. Of course, I'm newer at this and always open to suggestions.

Lordsmurf; Don't know why my question doesn't make sense. Iso creation is like 'bronzing it'? Why wouldn't DVD player play the burned DVD anymore?

Thanks

I guess you want a DVD-Video (video_ts folder with vob,ifo,bup files) or? Then you can't just "make" an iso that simple. You must author it, using for example gui for dvd author(it can output it as iso also).

See, I thought mpeg2 is the format needed to make/burn DVD video. So, why not use imgbrn>build>load the mpeg2 clips in buildlist(isn't THIS considered authoring, to extent necessary?), keep size under 4.35GB, then click to make the iso file. Burn iso to DVD. ?

Looks like it may do all that, just haven't seen what a burn will yield. If I comprehend Lordsmurf, it may/will not play in a DVD player?

In the analog-digital video converter package I have, the hardware and capture s/w is great. B/c it has the h/w box, PC power is not a critical element as in a s/w-only pkg as I've read these take hours each encode, etc, with crashes and freezes common. Have never had a startover yet.

But the accessory s/w to 'author?' or build and make and burn, is difficult and adds compression at each step I think. That's why I ask another way.

An ISO is basically just a container to hold multiple files or anything you want.

You can make an ISO full of text files, photos, anything you want.
Just dropping some mpg2 files into an ISO will no more make it dvd video player compatible than zipping them up into a zip file.

So, why not use imgbrn>build>load the mpeg2 clips in buildlist(isn't THIS considered authoring,

Not in anyones wildest imagination!!!
Well... maybe someones 8)

Me thinks you need to do some reading in the links found at the upper left hand corner of your screen.

Up where it say's WHAT IS under DVD & HOW TO under Author
Then maybe look under the TOOLS section, sub-section Authoring (DVD)

Yes, mpeg2 is is the format for dvd-video but you must author it to VOB,ifo,bup files and Imgburn will just make a iso with mpeg2 files and it's not a dvd-video.

The "authoring" step does not degrade or compress the video in any way.

While there are a few DVD players which will handle raw mpg video on disk, most will not. The mpg files, which must first be DVD-compatible, must also be packaged in a special way for a DVD player to handle. There are a number of different authoring programs, it usually is quite fast and not overly complex.

Thanks for the replies, all informed. I know a bit more now thanks to your answers and my doing, practicing, making a few coasters.

One thing not clear on is "encoding" or "transcoding". I've read some hated s/w that
"re-encoded" their file even though they said it didn't need it. So encoding is bad?, more in a repetitive sense, each encode compresses file and degrades quality?
(Question #s for easy ref.)

1) My Video/DVD s/w has 'Edit' tab where u select raw clips(long list of supported types), storyboard/timeline etc., basically build a custom video from clips, pics, music and then can output mpeg2, etc to HD using "Export". Is this considered 'encoding'? I believe not,
'Export' process takes abt 1/2 the time as #2 process next. If this is not 'encoding', is the process otherwise degrading, b/c of compression e.g.

2) In 'Create' tab where you build a DVD from raw or built vids(above para)by dragging vid icon into DVD Menu area, finally load DVD, then, goes thru a process, some part of which I believe is 'encoding'. The steps taking >minute, 'Transcoding', 'Authoring', 'Writing file'. This IS an encoding b/c I read that encoding and transcoding mean same.?

3) Finally, back at the start, when capturing/converting?/encoding?/writingtoHD the analog video, isn't this encoding too? I know there's lots going on during the capture process with the h/w box. Including I'm told, the 'Filtering' by h/w at capture -- and that's one factor why output DVD quality, esp video, is superior to analog source. Whatever reason don't know, it is superior and that was the most unexpected, pleasant surprise abt the pkg, how DVD video quality noticeably improved vs original.

Helpful for sure.
