Access Violation during DVD burning

lynns wrote on 10/10/2014, 5:01 PM

I’m trying to burn a DVD of a 2 hour long video (it’s basically just a lot of photos, and video files with music) I was hoping this wouldn’t happen, but it did- about half way through the burning, a window popped up saying “ACCESS VIOLATION”. I really don’t know what went wrong, but it seems like the longer the video, the better a chance the DVD has of some error occurring during the burning process.
I don’t know what I would do without this community, thank you so much for any advice or help you may be able to offer me!

A couple of things to suggest:
1. 2 hours for standard (single-layer) DVD disc is pushing it a bit! You will inevitably have a lower quality in the final output. Perhaps that (lower quality = lower bit rate) is somehow causing the error?
2. I notice you are burning direct to disc. Have you tried burning to "Image Recorder", i.e. creating a disc image which you can then burn with any other burning app that will burn from a disc image? The reason for this suggestion is to remove the possibility that the actual DVD disc is "faulty".

I tried your suggestion of using the image recorder, but the same error still popped up (I think around the same time it did the first time when I was just burning it.) It says before I start burning, that there’s even still a little more space left on the disc, so I don’t think the amount of room is the problem… I could be wrong, though! Thank you for your help.

If the attempt to burn to Image Recorder is also failing at about the same time as the original attempt, I suspect there is something on the timeline at that point that is causing VPX to fail. I would suggest looking very carefully at the section around the timeline "point of failure". Is there anything "unusual" happening there, perhaps a transition or other effect that might be causing this? Perhaps some effect that is only used there? Or perhaps an effect that is normally OK but in combination with something else happening at that point is causing the Access Violation. I notice the error message speaks of Quick Time. Are you using .mov files at this problem point? Could one of them have some type of "corruption"?

Finally, if there is nothing obviously wrong at the time of the breakdown, if you remove one or more files at this point on the timeline (and close the resulting gap, of course) does the DVD export then proceed as normal? The idea here is to try to remove and eliminate the file that is causing the error.

Alternatively, could you create a Range covering, say about two minutes before the breakdown point to about two minutes after and then try exporting only this range? Does that successfully export?

You mention that VPX tells you there should be space on the disc after burning. Can you see, by clicking the "Encoder Settings" button before you begin a full export, what the bit rate is that VPX is using?
