Can't render my first movie on Pro 11

Morning All

I have recently upgraded to Pro 11 from Pro 10.

I am using Sony camcorder footage (AVCHD?) and have never had a problem with rendering before with Pro 10. I was using one of the DVD Architect templates and have been very happy with the results.

I have a windows 7 64 bit Machine.

I have been working on my first movie with Pro 11 and used the Main concept MPEG2 Blue Ray template with a "=" to render the movie.

At first everything looks fine and the estimated time to completion spins out to 1hr and 30 minutes.

However when the rendering is 25% complete the video preview window goes black but it continues rendering and the estimated time to complete just gets longer but the 25% does not move.

Could anybody hazzard a guess what's going on here please?

The movie utilises the New Blue 3D titler quite a bit and I have been experiencing regular crashes everytime I try to use it but at no other time. Could this be relevant?

I haven't tried any other templates to render the movie yet.

Is there any thing I could try which would help the forum to help me?

Thanks

To repeat your situation - you are rendering a video stream for a Blu-ray disc from SonyVegasPro11 timeline. Edits include many NewBlue 3d titler events?

1) There should not be any audio in the stream - just video for pass number one.
2) The timeline plays fine in the preview window of SCSVegasP11?
3) Timeline end point -how long is your program? Should not be real long!

If you are meeting the above conditions, let me suggest that most renders fail because of a spoiled/damaged event. Test this by selecting a region of the timeline and choosing only that region for a test render. Keep doing this until you find a section of the timeline that hangs the render...that shall be your clue to locating a bad event.

Hi Video IT Guy

Yes

1) Yes
2) Yes
3) 2 hours and 10 minutes

OK I'll give it a go.

Thanks a lot

Perhaps some workflow issues! Thank you for answering my first questions. By the time you read this, you may have moved on, but I did want to point out some potential problems here.

1) Your timeline length in the editor is unwise in my opinion. You have not mentioned inserting markers for creating chapters in the Blu-ray disc, so I assume you are going after the timeline in one swoop.

2) Here is what I would do to save your project from the "potential" problems you are having.
A.) Think about arbitrarily dividing your timeline into approximate-- equal 1/4 portions. Just keep that in your mind, don't physically change anything to SCSPro11 Timeline. Then choose to render each section as I suggested previously. Render sections so that they have 10-20 sec overlap at least from the end of the first to the beginning of the next...reason for this in just a moment.
B) With each section successfully rendered to video and audio streams, then import into DVDAProArchitect for a Mpeg2- Blu-ray project. Set in/out points in the DVDAProArchitect time line so that you have now four "scene" sets that may have just a tiny overlap to help viewer with continuity in the final disc.

Author and complete your Blu-ray disc, burn and enjoy.

Hi

Yes I have markers in the timeline for creating chapters in the Blu-ray disc and I normally render in one fell swoop.

A) Understood
B) Haven't done this before but makes sense

I'll try this tonight.

Incidentally, I did render the whole movie successfully last night (Took 4.5 hours) using the Sony AVC/MVC Blu-Ray template.

Would I have a problem trying to burn a Blu-Ray in DVDA with this file? I guess the quality is lower or could I "recompress" to a higher bit rate in DVDA?

Again failed to render using the Main concept MPEG 2 format and the screen blacked out at the same point which is the end of a slideshow imported from Vegas Movie Studio.

Can I conclude anything on the basis that I can render successfully in one format but not another?

I'm a bit confused by that to be honest.

Thanks for your help.

To Wovian:
I think the process you went through did identify a culprit in your timeline - and notice how you said the end of the event- that really suggests you have a situation with an incomplete GOP. This is something that will hang MPEG encoders. Good trace!

The difference for a burn on Sony AVC/versus Mpeg2 will not generally be noticeable. Many people on this forum have suggested that VPro11 has been engineered to steer AVC to web use - so that is something to keep in mind.

For me ( I don't touch VPro11) , the difference to the nth degree is that given hardware, the Mpeg2 encode places a lot less stress on the system. Generally the encode is more efficient and the result is first class. A burn on Blu-ray disc is going to be most compatible with different players, but the space taken out of disk volume will be much higher.

Your conclusion of this situation : read my comments on your workflow again.... you can easily have spoiled events on the timeline and it is really difficult to trace. I do all slideshow work either inside VegasPro or use the .mov container for a port from Photodex ProShow Gold. That workflow eliminates the temper tantrums of unclosed GOPS.

Thanks again for the help. Very much appreciated.

I use VMS for the slideshow because it's easier than Pro which seems very manual intensive to prepare a slideshow (I could have 4 on one movie and each could be 80 images) and I've never had a problem.

Then again I haven't used Pro 11 before..........!!!!
