Prepare BluRay Missing File Error

phoo wrote on 4/30/2016, 10:35 AM
A file is being reported missing during preparation for a blu-ray disk. The error shows that the file missing is 0022.m2ts (?), yet there is no other info about why it's missing. Just says unknown. (forgive me for not having the complete exact text)

I have prepared and burned this project successfully once before, but I did some minor menu edits, fixed a typo in the main menu text and adjusted the button locations a little. So a re-prepare was needed.

I have previewed to make sure all the underlying assets are good (although not all perfect) and are pre-rendered in formats that will work with no re rendering (for the most part). The only messages I get at the start of Prepare are that the audio for the four menus will need recompressing. Viewing Optimize confirms that.

Navigation is good and there are no broken links.

Yet, all of these assets worked fine as-is once, assuming the error is indeed a bad asset..

I am using DVDA 6 on Win10. The project is blu-ray for 25g disks.

After a reboot, deletion of all existing output files, and re-try, still failed after almost four hours. (this was halfway done when I originally posted)

The project had the video format as AVC instead of MPG-2, and audio as AC-3 instead of PCM. Don't know why as I hadn't changed them since creating the project.

What ARE the proper defaults for a Blu-Ray?

Anyway, set the project to MPG-2 and PCM and some of the recompressing required checks in "Optimize..." are now green. Almost all individual item settings in Optimize for Video and Audio are set to "Use Project"

I had not checked these when the prepare and burn worked, so I don't know what they were then.

I have update the project for MPG-2 and PCM and am trying again.

Either format can be used on Blura so the defaults should match your source, in this case MPEG (m2ts)

I have success this time, just by changing the project video and audio settings.

Prepare and rendering of the ISO took a little over 1:30 total.

All video assets are MP4. All audio assets are PCM 48K 32bit Type 1 Broadcast. These have not been chanced since the start -- success - failure - success.

It's unfortunate that DVDAPro needed to get 3 hours into preparing this project to hit an error, then report that it's an unknown error, after being successful once.

If this was indeed an error caused by the project settings (set to AVC and AC-3) and if those were incompatible with the assets as they are then it seems like DVDA should have been able to throw up a reasonable warning, instead of just telling me the files would be recompressed.

If these recompressions are not supported then throw a flag. If they are supported then there is a bug in the app and I hit it.

The "recompression needed " is a warning.

Use the bluray templates in rendering options for your best final product.

Yet, a warning shouldn't result in an error, especially an error that doesn't happen until nearly 3 hours into a prepare.

I did use the templates and tried to match the templates as best as I could between Movie Studio and DVDA. I assume mistakes were made. So be it.

I'm currently recreating this content as a DVD from the ground up (not bluray) and have discovered that the only new DVD Project choices in Movie Studio are 29.970 fps and 23.976 fps, yet the only new DVD Menu Based Projects are 60i and 50i.

In this case there is no way to use the templates and have matching projects. Yes, I know 60 and 50 are double 30 and 24, but given this there is no way to just use the templates and have it work. I'm still left having to figure out the best render format.

29.97fps = 60i , this is NTSC (USA and a few others)Standard
23.976 is a film rate. Unless you shot at this framerate, do not use it.
50i is PAL standard (Europe)

If you shot at 29.97, then it is best to stay that way through the whole process using 60i.

60i means 60 FIELDS interlaced, which is 29.97 FRAMES per second. (they round it off to 60 just be make it simple but it is not exactly 60).

23.976 is the TV version of 24frames per second which is the standard film rate. When used on a DVD, it needs to have a flag set that will convert to 29.97 during playback.

50i is 25 frames per second.

If you are using MP4 files, then you should not use MPEG as your project settings. That will cause a re-render (recompression) of your video.
MP4 is an AVC file I believe.

Use the MPEG templates and set your DVDA project to MPEG. A DVD must be an MPEG file.

If that is the case then I have indeed hit a bug. That will not work, as it cases the error well into prepare.

Using MPG-2 in the project settings is the only option that is working, and does not seem to force a recompress for most content, including the mp4 videos.

Thanks for the info. Much of this is new to me, being a lifelong audio only guy.

Thanks for the info. I really appreciate it.
