Weird transcoding glitch

[golinux]

I thought I was being very clever to burn my ISOs to 'best" quality and then let Disk Copier transcode to fit to disk. The quality is great! But when I actually played one from beginning to end, I discovered a weird glitch at about 60 minutes of 114 minutes on several disks.

 

Around that time, my set top player starts a stop and go 'stutter' and the timer gets stuck in a loop and keeps repeating about 30 seconds of time over and over while the video staggers forward. It plays a little better on my computer but is not very smooth. The timer on the computer does the same thing - it gets stuck in a loop and never moves past the loop. I tried different disks, different recording speeds, reburned the ISO and the result is the same. When I lower the quality, it plays fine.

 

Has anyone else noticed this strange behavior? And is there a workaround? As is, the transcoding function pretty useless.

[golinux]

Now, that certainly is a touchy feely term.

 

 

Interesting conclusion . . . touchy, feely is a very foreign concept here.

I don't think you do. I think you've got to burn to an .iso file and then use Disk Copier to burn to a video folder on your hard drive?

 

I didn't think there was such a feature but I am always willing to be enlightened

 

Hmmm . . . I assumed that was an option. Guess I kinda got ahead of myself in all the excitement of a glitch-free disk that works!!!

So the workaround is a really long workaround I'd rather put up with the 1 or 2 second glitch then waste a couple of more hours!

It is a Player issue, are you suggesting Roxio has to pay every Player manufacture in the world to fix their hardware/software???

 

V7 is done. There will be no more updates. I suspect that would apply to V8 too. While nothing official has been said, you don't see software companies spending money writing enhancements/fixes for software that is out of production!

Yeah, it takes a little longer but I can always find other things to do - like go online with my Linux box where I am right now. Aside from the pursuit of perfection, it was really frustrating to have to stop in the middle of a series of movements. Now I can do the show from beginning to end - situps, legs lifts and all! Me happy (and in good shape for an old lady).

Yeesh, James. No need to get so defensive. Your kneejerk reaction reminds me of M$ tech support. It's never THEIR fault; it's ALWAYS the software. Yeah, right.

 

Blame the player if you want but remember the glitch is also there on the computer (though not as noticable). And I never suggested an update to V7. I was just wondering if there was a workaround and one was offered via PM which I will try in a bit.

Well, perhaps I don't understand.

 

If I have an .iso file on my hard drive, I can open Disk Copier, select the file, and then Disk Copier gives me the option to burn to a DVD-Video folder on my hard drive. Then I can select a folder ( or choose a new folder ) to burn the File to on my hard drive.

 

Is that what we're trying to do or did I misunderstand? (Although it does seem like a long process. However, if you're excercising to the previously burned DVD..... maybe not. )

[golinux]

Another way to get to the video folders is to use Disk Image Loader. Just double click on the loaded ISO and the folders appear which can then be copied to your HD.

 

I must say that the quality of the disk that I worked on today is much improved from the previous renditions. It is clearer and has fewer 'warts' in addition to removing the stutter. I'll be processing all my disks like this from now on.

[Guest ml]

A slight correction.

 

I just made an over 1 hour production, used the 8.5 DVD option at the bottom of DVD Builder, burned to an .ISO file.

 

Then I used Disk Copier to burn the .ISO file to a DVD folder on the hard drive.

 

Disk Copier DID NOT shrink the files or transcode it again. All the .vob files were the same size as the .vob files in the .iso.

 

So if all you need is the .vob files in the .iso file, you don't have to mount a virtual drive, you can just use Disk Copier to burn the .iso file to the hard drive.

 

This would be important for version 7.1 users who do not have the Disk Image Loader included in their version and who find that they experience the 'glitch' at one hour.

[malatekid]

Here's the summary:

 

1) Use DVDBuilder to create the iso file at best quality

2) Open the Disc Image loader, thereby creating a virtual drive, and load the iso file from step 1

3) Copy the entire DVD-Video folder from the virtual drive to the hard drive

4) Run FixVts using the DVD-Video folder files just created in the hard drive (if you skip this step, the next step below will likely give an "invalid navigation structure" error message)

5) Run DVDShrink using the resulting files in item 4. This will create a new compressed DVD-Video folder (or an iso if you set DVDShrink to create one instead of DVD-Video folder)

6) Burn the DVD-Video folder (or the iso file, if applicable) from item 5

 

cdanteek shared this process with me during my rookie days.

 

As noted this process takes long. As most of my projects done in V7.5 were close to 120 minutes, the resulting lose/degradation in quality due to compression was not acceptable for the projects I made (anniversary, school plays, etc). I ended up using DL discs to accomodate the entire project.

If "kneejerk reaction" describes my response to someone who expects totally unreasonable product support, so be it…

 

If you are getting a workaround, care to share, or would that be too much to expect?

Unreasonable? Reality check needed.

 

A workaround is not official 'product support'. It is peer to peer sharing of expertise which is what I thought this forum was about.

 

I will share the solution if it solves the problem but that may take a while. Cement project is calling and then there will be a learning curve. If I'm lucky, I'll figure it out tonight in the wee hours. Otherwise might take a day or two.

 

Now take a deep breath and relax . . .

Since I don't make DVDs with more than one hour of video, I've never personally encountered this problem.

 

I appreciate your sharing this 'glitch' because I had considered burning some old VHS tapes that are over 1 hour.

 

I wonder what would happen if you split the titles into one hour each and used the option to 'play next title'. I wonder if you'd get the same 'glitch'. I might experiment with this when I get some time.....

[golinux]

Thanks for the very clever solution! That would certainly save time. HD to HD is faster than virtual drive to HD. I'll give it a try later . . .

 

Much later . . .

 

Bummer . . . I just tried this and it didn't work! When I tried to copy the folders, it started to transcode the files. Maybe I have a setting wrong in Disk Copier - though I don't think so . . .

I am quite relaxed thank you.

 

You keep qualifying and re-qualifying your remarks. Clearly this is something we are not going to agree on and I am happy to leave it at that.

ML: First try it and see if it even is a problem. I've been doing this from time to time since V7 and never seen it!

 

Now in the 200+ Movies I have made I have seen it even with best quality burns of less than an hour length. That was a media issue.

[grandpabruce]

Ok. That makes sense.

 

cdanteek, When you burn from an .iso file on your hard drive to a DVD-Video folder, you don't get an .iso file, you get the files that would be burned to the DVD in a folder.

 

But the transcoding is the part that I didn't understand.

 

So you need 7.5 to do this procedure because 7.1 doesn't have the Disk Image Loader.

 

Thanks for the info.

 

Version 7 and 7.1 had some problems for some folks, if they had any disk image loader like Daemon Tools or Alcohol 120% installed on their computers. Those image loaders rendered the EMC 7 as useless the same way that IE 7 does.

3) Copy the entire DVD ISO from the virtual drive to the hard drive

4) (if you skip this step, the next step below will likely give an "invalid navigation structure" error message)

 

Because the "invalid navigation structure" is the glitch!

I have the same or similar behaviour on all DVDs that I have created of videos that are > 60 minutes. The funny thing is that the playback behaviour is different on different stand alone DVD players. On the one player it it jumps back to a previuos point, I press stop on the remote, then play and the video plays Ok from then on. On the other player it "freezes" for about 5 seconds and then continues playing normally. On the 1st player this behaviour occurs always around the 65-70 minute mark while on the 2nd its always around the 62 minute mark. All these DVDs contain an about 90 minute video that was rendered to an iso file and then burned to DVD using Disc Copier. I have over a 100 of these DVDs that display this behaviour and it would be nice to know what causes this.

I have the same issue that myguggi described but this was in V7.5. I still have to watch the video (105 minutes) I created with EMC9 to see if the same problem persists.

So is the method of burning directly from an .iso on the hard drive to a DVD-Video folder on the hard drive an invalid method? It seems to me that both accomplish the same thing while eliminating the step of mounting a virtual drive.

[cdanteek]

No, Fixvts only works with folders not ISO that is why.

That doesn't work because Disk Copier transcodes the ISO when burning folders to the HD. In order to get the folders that are the original oversize burn, you have to use Disk Image Loader to copy the folders. At least that is what I found. If there is another method, I'd like to know.

Walt, I find it hard to comprehend someone burning over 100 DVD's with the same problem and putting up with it! Your DVD's should not do that!

It's an ongoing learning process. What do you think?

[golinux]

Didn't work for me. My DVDs are in three 24 or so minute segments (with return to menu as I only watch one per day) and the problem crops up in the third segment at the appointed time. Don't know what would happen if they were continuous. I am not hopeful it would work . . .

 

Clearly this is something we are not going to agree on and I am happy to leave it at that.

Yes, never the twain shall meet. Please leave it to the rest of us to sort it out.

I couldn't agree more!!

[Guest ml]

Yes, that worked! No more need to use Disk Image Loader to retrieve the folders. Thanks, ml and of course, myguggi too.

 

You're welcome!

 

I'm sorry I omitted the step about choosing DL when you selected the folder to burn it too. Many thanks to Walt for catching my memory lapse.
