HD Blueray Memory Shortage

drmathprog wrote on 3/29/2010, 4:44 PM

I've been testing out Neoscene as an aid in editing AVCHD video from my Panasonic HD camcorder. As a simple test, I filmed about an hour of my daughter's recent birthday party. I used Neoscene to transcode about 12 scene files from AVCHD to .AVI. I then placed te .AVI on the Vegas timeline, used Ultimate-S to provide a uniform 5 second transition between each scene resulting in a 57 minute project, and attempted to render to HDV 1080 60i. After about 10% completion, the render fails and complains of "lack of memory".

This is on a Intel Core 2 Quad Q6600 running Win 7 Pro in 64 bit with 8 Gig of memory on Vegas Pro 9C 64 bit.

It seems to me that I should be able to render such a project without memory issues. Am I expecting too much of Vegas using HD, or are there known issues that are causing me to stumble?

When batch transcoding you want to create exact copies of your source but in a different format so you shouldn't be using Ultimate-S to apply a 3 second fade in/out.

Here's the workflow I would recommend:

OPTION 1 - NO TRANSCODING
1. If all you are trying to do is end up with a DVD that has a series of clips with a 3 second cross fade between each clip I would just set up my AVCHD clips on the timeline and render straight MPEG2 using the DVD Architect NTSC Widescreen video stream and the Dolby Digital AC-3 Pro Default templates.

OPTION 2 - TRANSCODE
1. If you need to do more complicated things on the timeline and AVCHD makes editing too slow, then batch render a series of MXF files (one for each of your AVCHD clips) using exactly the same settings in MXF as in your source AVCHD (i.e., the "=" indicator discussed previously). If you start with 10 AVCHD files you will end up with 10 equivalent MXF files.

2. Place each of the resulting MXF clips on your timeline and edit as desired (cross fades, etc., then render to the MPEG2/AC3 templates as in option 1 above.

Hopefully I am understanding your problem correctly and this will help.

Jerry;

Thanks. That's very helpful.

I'm trying to end up with a Blu-ray disc. Doesn't the final render need to be to something like HD EX 1920x1080 60i rather than to DVDA NTSC Widescreen video stream and AC-3 Pro audio?

Another road block. When I try to create a "single movie" Blu-ray project in DVDA, when I select my rendered 1920x1080 60i file (which is what the DVDA template is asking for) DVDA goes "not responding".

Am I on the cutting edge here, or have people successfully made many DVDA Blu-ray discs?

Yes, if you are makin blu-ray you would render to using one of those templates. Not sure about the not responding. Usually DVDA is pretty stable but I am having my own (but different) problems with it this morning. I do get "not responding" with Vegas 9c fromt time to time.

John, I wish that worked with Vegas 9c ;-).
