Pro X2 - Hybrid DVD+RW Question

[dalemccl]

For anyone using DVD+RW media to burn hybrid discs from AVCHD with Pro X2, do you experience the following issue with +RW when burning AVCHD:

Pro X2 gets to the last burning step, (it names that step "making ready for eject" or something like that.) That step proceeds from 0% to 99% in about 2-3 minutes and then takes another 10-12 minutes to complete the last 1%. (I am referring to the percent progress on the lower progress bar entitled "detailed progress".)

After the 10-12 minutes, it completes that 1% and pops up the message that says the disc has been burned sucessfully. The disc plays OK in my Blu-ray player.

During those 10-12 minutes, Vista's task manager shows that Pro X2 is not using CPU time and is doing very little hard disk activity. Makes me wonder what it is doing during those 10-12 minutes.

First of all I'm still using VS11.5, and I've not burned any hybrid discs - not having a player in which I could play them.

What is the size of your project, and how long does it take to complete the whole disc creation process?

Since you are using an RW disc, the burn speed must also be quite low - what burn speed are you using?

If the overall disc creation time is OK, it may simply be that X2 is mis-representing it's activities in the progress reports.

You could possibly check that out by burning a very short test project. You might then be able to see if the 12 minutes is actually an additional amount of time expended after the main burn has completed, or if, with the shorter project, that last 1% takes significantly less than 12 minutes.

DVD burners vary quite a lot in the time they take to write the "lead-in" and "lead-out" sections of a disc. I have an LG which seems to be noticeably quicker in that regard than my other burners.

You could test that by burning with another burner, if you have one.

Finally, if you produce a "keeper" project, you could also compare the burning behaviour when using a DVD+R or -R disc.

I did a test where I burned the same 13 minute AVCHD project to 2 hybrid discs - one a DVD+R and the other a DVD+RW. I burned both at 4x.

The +RW took 17 minutes 19 seconds of which 20 seconds was in the erasing the disc step, so the net time without the erase was about 17 minutes. The last 10 of those 17 minutes was for the last 1% of the final step which Pro X2 named "making the disc ready for eject."

The +R took under 3 minutes.

So not only does the +RW take longer to burn because of those last 10 minutes, it is still over twice as slow even without those 10 minutes. 7 minutes vs. 3.

One odd thing is that it took under 3 minutes to burn 13 minutes of AVCHD to the DVD+R at 4x. Seems like it should have taken longer at that slow speed. Makes me wonder if Pro X2 really used 4x like I told it to.

Have you checked to see if there is updated firmware for your DVD burner?

Turns out there was an upgrade available. I downloaded and applied it. Then re-burned a DVD+RW from the same AVCHD file as before, and it cut the burn time from 17 minutes to 15. Still a lot more than the DVD+R at the same 4x burn speed (3 minutes). And it still took a long time for the last 1%.

Still, I'm glad to gain a couple minutes with the new firmware. Thanks.

During those 10-12 minutes, Vista's task manager shows that Pro X2 is not using CPU time and is doing very little hard disk activity. Makes me wonder what it is doing during those 10-12 minutes.

I think that it's formatting the rest of the DVD+RW in the UDF 2.6 format since your making an AVCHD disk and it's not a multi-session dvd+rw.

I would import the AVCHD disk video files that you burned and see how much disk space they actually used on the DVD+RW. I think the less amount of video you put on the disk the longer the lead-out takes and vice-versa.

I'll make an AVCHD disk in MF6+ and let you know if the lead-out takes a long time to complete on a DVD+RW disk. I think it may need to format the whole disk in UDF 2.6 format maybe, not sure.

Thanks etech6355, I'll look forward to your results.


I checked the "Properties" of the two hybrid discs to find out how much space had been used vs. the unused space. These discs were burned from the same AVCHD file that was created by Pro X2's Create Disc function.

DVD+RW. Used 4.7 gb, Unused 0 GB.
DVD+R Used a little over 1 GB, Unused: 3.5 GB

On both discs the .m2ts file in the STREAM folder was 1.05 GB.

Checking the size of the various files on the +RW, they only added up to a little over 1 GB, which was mostly the .m2ts file. So the files add up to much less than the 4.7 GB that Properties said was used.

Unless this is just a difference in how Vista displays available space information for +RW vs. +R, then it would seem to support your idea that Pro X2 is formatting the rest of the disc space that is not used by the video. The progress bar only shows a "Formating" step early in the burn and this step only takes a few seconds. But it may be doing more formating at the end once it knows how much space is left after burning the video.

This raises the question of whether VS actually needs to format the rest of the space because of DVD+RW standards, or whether it is doing it unecessarily. It doesn't do it for AVCHD on +R. It doesn't do it for standard definition DVD written to +RW. It is only the combination of AVCHD and +RW where it is formatting the rest of the space and taking a long time for that last 1%.

I did several tests with several brands and types because I was puzzled (and still am) why +RW didn't playback on my BD player. RW(+and-) seem to get allways filled up. Last 1% takes a long time, depending on the amount od data (less data= longer 1% delay). In "properties" there is never "free space" for wathever type (+/-RW and +/-R). DVD+R and -R show the real amount of data in "properties" (used...but nothing "free") With Nero info tool, +RW allways shows full (4.37 GB) while -RW and +/- R show the real size of the data. All my disc show ISO9660 UDF as file format.

It could be the media, burner or the version of +RW dvd's.
Not sure.
I do know that the burned AVCHD disks should be in the UDF 2.6 format which can handle very large files.

I made an AVCHD disk with approx 1.1gig of video on it.
MF6+ first (quickly) formatted the disk and then burnt it at 2.4x which did not take very long. I was waiting for the write-out and the pop-up displayed saying disk burning complete.

So, this is not happening using MF6+.
When I get time I'll see if X2 has a problem or not burning the same videos.
Again, I'll report back (not sure when! )
