How much is too much for a DVD?

[LuckyProducer]

Hey guys, I made a 98 minute video for a wedding and I pretty much had to recompress it in DVD Architecht to fit it in the 4.7 GB DVD-Rs I have. It seems as though the end of the DVD starts getting glitchy and stops. I clean it and blew onto my DVD player and it gets better, but then it gets bad again. It sorta comes and goes. I tried it on different DVD players and it's fine. One little finger print on the edge makes it glitchy. Does this has to do with because I pretty much filled the DVD to the very top? Does that matter or no? Please let me know. I also burned it at 4x so speed is not the issue. I am worried about my clients coming back to me saying that my products are glitchy! Ah! God bless!

feature films are pressed to dual layer disc so they are larger than 4.7g. Try burning to 8gig dual layer disks or split into 2 45min 4.7gig dvds

whatever you are using to burn will just compress the crap out of it to fit it on the 4.7g

lucky,

I don't think that the glitches are because you filled up your 4gig dvd. It sounds like it might be the player you viewed it on since it comes and goes. Keep touble shooting, but it may be worth a shot with a DVD DL.

BTW, I like your sig...check out some of my christian based films if you have time.

On a "4.7GB" DVD you can hold 4.3GB. Apparently Plextor drives will allow you to overburn your discs, which will let you use more space. This isn't recommended though because it could lead to disc errors.

Here is some more DVD info.

i have shot, edited, authored, burned, and sold thousands of dvds... your program length of 98 minutes is not relevant to the size of the dvd disk, it's the quality of the compression that counts... in terms of fitting a 98 minute program onto a dvd disk, you only needed to have selected the correct bitrate for the mpeg2 encoding, i use the videohelp bitrate calculator.

i first tried dvd architect a couple of weeks ago, and it was a disaster... the program refused to accept an mpeg2 file that was 100% dvd legal; it was a file that i had encoded with procoder 3, and dvd architect wanted to recompress it.

never recompress an mpeg2 file that you authored for dvd, it will ruin the picture quality.

when you burn to quality media like taiyo-yuden, you can fill the disk up all the way, and unless the media is defective, it will play to the end with no problems... burn speed is not a factor these days.

Like OSV said, buying media that are not cheap is key. I had people question why I was paying $35 for a spindle of DVD-Rs that one could get for $20 or whatever but Taiyo Yuden's have never let me down. I confidently burn to the disc's edge and have never had issues with them.

Their CD-Rs are great as well. Cheap discs that are all scratched up skip quite a bit. The TYs that are just as badly scratched play smoothly. That tells me a lot about the quality of those Japanese discs.

False. When a laser decays, the calibration set in the firmware still thinks that the laser is shooting at a certain intensity. When laser intensity is lower than what is pre-set in the firmware , the pits in the disc aren't burned deep enough and that will cause read errors. A more expensive burner may have a re-calibration preset after the laser has been on for so many hours, but don't expect to see that in a cheaper drive.

Keep in mind that the laser in your DVD Burner will start to decay after 2 years of normal use. Try burning at the lowest possible speeds with older drives, and upgrade the drive's firmware if possible to alleviate these issues.

Stay away from Sony or TEAC Drives since they seem to be the cheapest in build quality. (Unfortunately last I checked, Apple exclusively used Sony Burners in their pro systems). LG and Lite-On make great DVD-Burner drives. You can always put one of these into a 5.25 external drive case and burn to that if your host software supports it.

Burn on DVD+R and Make sure the software supports bookType BitSetting as DVD-ROM for increased compatibility. (See This for more info)

not a factor in the real world, and i have thousands of burned dvds to prove it.

and i'm not sure how you can equivilate burn speed with laser intensity... your inference is that the laser is burning for a shorter period of time when the burn speed is higher, but you haven't provided any data to back that up.

that is another old wives tale, and again, i have thousands of burned dvd-rs that prove how compatible the format is... btw, lite-on used to use sony burners; i know, because my neighbor had a lite-on dvd recorder go out, and he had to ship it to sony in rancho bernardo to be repaired.

i do agree with your assessment of the sony burners, tho, they have a history of weak lasers, while pioneer upped the laser intensity years ago.
