rendering in black
hi folks,
i shot some video at my niece’s wedding and have put it together along with a photo montage i created with photodex’s proshow.
the proshow file is approx 500 MB.
consequently (at least i think so), vegas pro (9.0) is bogging down.
on my six core desktop (built so i can render big projects), i run out of virtual memory and vegas shuts down. (rather than create one long file with the run up to this wedding and include the wedding footage, i’ve had to section out this 7 minute piece as a separate file.)so i copied the project folder onto an external, hooked up to my laptop and ran the veg file there.
i can at least render the project — but there are sections that render in black. (https://www.youtube.com/watch?v=JDfhkdvtAS4 — black at approx 6:36)
i’ve rendered it several times — black shows up in different places.
i’ve very carefully checked all my cuts and edits — no random areas of black.video was shot in hd with a kodak zi8 (those are mov files)
the proshow piece is an avi but created using 16:9 settings.)i’ve rendered in several different formats — all giving me pretty much the same results (random areas of black).
the final format i used is sony avc using the provided 16:9 hd 25p template.
(on the desktop, when i load this project, i watch the memory usage go up over 7 figures ((yes, upwards to 1,250,000)).
and even on the laptop it’s up around 900,000.).again, here’s the vid — https://www.youtube.com/watch?v=JDfhkdvtAS4
random black around 6:36.my question?
not sure really — random black caused by what (i certainly have theories).
vegas can’t handle 1/2 gb files without crapping out?
i need more than a six core processor loaded to the gills with memory?
should i have rendered it to a different format?thoughts?
suggestions?
thanks

What version of Vegas are you using. I’ve seen random black frames with the Kodak Zi8 MOV files and Vegas Movie Studio HD 10.
BTW, 500MB is tiny in the world of video editing. Most files are multi-gigabyte in size so a 500MB file wouldn’t bog down Vegas. What codec did you use the create this AVI file? Perhaps codec is the problem.

intel iyuv
microsoft 1
indeo 5.1
divx 6.9.2
and techsmith’s camtasia codecthis piece was rendered at 1280 x 720

Try rendering using Sony AVC with the Internet 16:9 30p template. If this causes black frames then you might have to contact Sony (although they will tell you to upgrade to version 10.0 if it’s a bug since they are no longer fixing 9.0) Most of the black frame bugs that I encountered were fixed in 9.0d so 9.0e should be working but you never know.

thanks john. i originally tried the 30 template — same problem.
(i thought perhaps i was over-taxing the system).
think an upgrade to 10 is worth a shot? -
[tom edwards] “think an upgrade to 10 is worth a shot?”
I wouldn’t blindly upgrade. Download the trial of 10 and see if it has the same problem. If it doesn’t… you have the answer to your question. 😉
