BD-R burning problem

[LCT1000]

Hi,

I have been burning files onto BD-R for over a year now. Recently I've noticed that the files on finished disc jump ever so slightly. After a while you get used to it and its barely noticeable but I just want to know if anyone knows why this is happening?

I used to burn on Roxio My DVD on a Windows Laptop but then I got a MacBook Pro and now burn on Roxio Toast. The same thing happens on both.

You need to be more specific about the problem. "The files jump" means nothing. If you're talking about video files glitching then it could be any number of things. Bad disc, bad burn, bad player, etc.

Generally I would suggest you burn using IMGBurn and always use the verify-after-burn option to ensure the data on the disc is fully readable and bit-accurate. Burn at the rated speed or a notch lower but don't burn at the slowest speed possible as this is an outdated and silly practice.

Scan the quality of the burn/disc with Optidrivecontrol or Nero Disc speed. (Will only work if your drive supports quality scans.)

I would always generate a checksum (eg sfv) of every file you are burning and store it on the disc or elsewhere to check for future corruption.

Is it happening shortly after the film/file starts and just before it ends? What are you using to capture?

I might be having the same problem.

The movie/footage on the disc jumps/jitters ever few seconds. Ever since I got my MacBook I thought I had escaped this problem. However, on the disc that I burned on my Mac the jumping is less noticeable as it was on my Windows Laptop. It appears that the jumping occurs every few seconds for about 30 seconds then it plays fine for another 30 seconds, then continues to jump again. The original video files do NOT do this.

It's happened a lot over the past few months so I don't think it's the discs. . I thought it could be Roxio products so I tried burning a disc with a more simple program but it gave me the same result. It may be the disc drive. Having said that, I've had a few successful burns where this 'jumping' hasn't occurred.

Could it have anything to do with the video files? Roxio Toast recognises all of my content as being in NTSC (which I don't think they all are) and asks me if I want to convert it to PAL. I select 'No' because it wold take a huge amount of time. Could this be the problem? Should I select 'Yes'?

slow the burn speed to about 4x,try dvdfab use a different brand of media such as tdk or verbatim stay away from memorex
do not get on the internet while burning a disc

Is DVDFab free? Also I'm using TDK Blu-ray discs at the minute.

no dvdfab is not free

it could be a number of things... the player, your bd-r drive, the files...

i would burn on the slowest speed possible, and you could try verifying the disc after.

imgburn is the best program to use, and it's free.

You need to provide more information so that a better analysis can be thought through. When you say, "files" what are the format of these files? Are they VOB, MKV, AVI, MP4, etc.? Are these files being burnt straight from another disk? Or are they files from a NAS or from the local. Like others have mentioned prior, there could be numerous challenges that could keep the process from burning a good burn. If you are burning an ISO file, then the best application to us is Imgburn. It is free and 95% rock solid. I say 95% because I have seen Imgburn faulty with an earlier version, But the newer version of Imgburn is very good. What kind of BR media are you using to burn? The quality of the media is important for burning video playback.

There are a lot of moving parts int this equation that can cause jitter. I don't think the previous members questions are unreasonable. After all we are trying to help.

Here are a few more questions that may provide some clarity on your issue.


What is the source of the material? Camcorder, Ripped Disk?
What are you using to encode the film/material?
What is the frame rate of the source material?
What is the frame rate of the area you are in?
What are you viewing the burned disc on?

Thanks for your help so far guys. Okay, the files vary. On my Windows Laptop I've used MKV's, MP4's and MPEG2's and the jittering happened on all of them. So far on my Mac I've only tried MKV's so I don't know if it happens on Mac with the other files as of yet. I have tired VOB files and they work perfectly. The files are all downloaded from the internet and they are 720p or 1080p files. I'm viewing the discs on my Blu-ray player, as well as on my Macbook.
I hope this information helps!

Can Imgburn use MKV, MP4 files? Can it make menus etc?

For converting video files, I would recommend Wondershare software. It does a pretty good job. However, Imgburn only supports ISO files. I believe that is all it knows. During your burns, are there any other processing running on the system/s? If you are running other apps during the burn, this will cause problems for the finish results. If your files play without an issue from your systems, then there is nothing wrong with your video files. But if your burns are jerky, jittery, skipping or freezing, then it would suggest your systems do not have the required resources to burn. First thing to determine is if you have the resources to burn without the systems starving for more resources during a burn. If you have high CPU, RAM or HDD usage during a burn, then you will need to add more resources to your system. During a burn, you can select "test" mode and then load performance monitor and see how your system reacts during a burn process.

On my Mac, I have problems with MKVs jumping when I playback using VLC, but not with Plex. The problem has to do with a combination of file size and VLC not accessing the full use of the processor, I believe. I don't know if that is the case for you, but you might try a different player app and see.

Also, if your home blu-ray player supports files burned onto disk, try them in that and see how they play.

You also might try copying the file from the disk to the hard drive of your computer to see if the problem is with the file or with playback off the disk.

Imgburn does not author disc. DVD Authoring and Blu-ray authoring is not that different in idea. After all its round with a hole in it? But things are deff different. Off the top of my head I believe that the folder/ file,
structure/ heirarchy is completely different.

If Imgburn detects the media files that belong to a partiuclar type of media, imgburn will suggest the way it should handle those files. And it will burn them accordingly. But AFAIK it has more to do with the folder structure than than the media that Imgburn detects.

http://forum.imgburn.com/index.php?/...using-imgburn/

Wait I know you are thinking that I just said Imgburn can not but a few lines later i mention that it can.

Imgburn can not author a disc because A) it does not create menus B) you have to make sure your files are encoded in whatever format that makes it compliant for blus.

I haven't done authoring or post production work for ages but I'm pretty sure throwing some avis, mkvs, etc into imgburn will not fly.

When you state that you use VOB files and they work perfectly it really does explain a lot mainly because VOB files are already encoded for you in a manner that makes them DVD compliant.

What Imgburn can do is burn the disc or the create the disc img, essentially burning a image of the disc on your hard drive.

What are you using to encode/ burn/ author your files on your windows computer?

Everything you mentioned above is correct. There are so many moving parts/ variables in the production chain that its not funny.

I suggest the OP gets some RW's because I can see some coasters coming in his future.

Now If he can author them, burn them to a disc image, mount them and play them. He will be that much closer to getting a successful burn with physical media.

There are tons of encoders out there. Wondershare was the only encoder that I could use to convert/ transcode a NTSC DVD into PAL correctly 100% of the time.

In fact for shit and giggles I once threw a disc image at it. 4 days later it was done.

I may have been able to do it with CCE but the level of programing involved with AVISynth, just never worked well in my favour.

Who does that? Wondershare can LOL.

Other notable encoders are Cinema Craft Encoder. But it requires AVISynth to import the commands into it. One can use it the way it is. But if you want to access to the heart of the software and get all you can out of it, You need to Avisynth.

Simply put CCE is not for the faint of heart nor wallet. CCE is commercial/ professional software.

HCenc and Tmpgenc are excellent freeware encoders. Great Gui, good quality output.

So, onyxbfly, what you are essentially saying is that since .VOB files work fine, the problem is less likely to be the PC/MAC, burning software, or media. Instead, it is more likely that the encode of the video is producing an encoded video stream that the player cannot handle.

From my limited experience, I would agree with this. A video stream often consists of a base or "key" frame followed by a set of "delta" or change data as time goes on until another key frame occurs in the stream. You can also think of this as "look ahead". A friend fooling around with various amounts of "look ahead" was able to produce disks with so much that his player would not handle it. Obviously, his PC software did.

So, perhaps the solution is to look at the settings used to perform the encode. An experiment or two would not hurt.

Good luck.

If you're trying to burn Blu-ray movies, you are going to have playback difficulties because, blu-ray movies are copy protected extensively, and they are not supposed to be pirated in the first place. So If the result of your copies are distorted or scrambled, then you know why. Asking for tutorial advice, instructions or recommendations on how to pirate blu-ray movies is not allowed to be discussed on this forum because it's illegal, and this website will not condone it.

A VOB file is essentially a container. It is MPEG 2 file that contains audio/ video.VOB files also contain the information that pertains to disc instruction (navigation and menus etc.)

IIRC a keyframe is the start and end of scene and or segment.

Yep you got it, someone could author/ encode a disc in such a way that it would only work on a pc video suite. Hardware players have a specific set of rules that must be adhered to.

Even if you burned the disc as a image and mounted it, I believe depending on the player it woudl tell you that file structure is not correct. But if you were to open the disc you would be able to play the VOBs etc. Sorry its been a while since I have been at the editing desk LOL.

I'll see what one of the resident egg heads at work has to say about it. This egg head changed hats a while ago.

You're correct. I can see where this discussion can lead down a slippery slope.
