Slow and flakey render
I’m trying to render a fairly complex project to mpeg-dvd. The source video is HDV mpeg with lots of color correction (done in adjustment layers), many instances of masks, image stabilization, clone stamping and even one photoshop sequence. Some shots have three or more of these types of image massaging. The video is about 19 minutes in length. The project uses NTSC color space and the project is set to 16 bbp. The audio is 16 bit 48khz.
The machine it’s on is a quad core Intel with 2 gb of memory. I’m using the CS3 version of After Effects.
Problem one. When I try to render the main composition to mpeg-dvd, the render usually fails anywhere from two to five minutes in. The log files are totally uninformative as to the problem. I’d rather not try to glue together a series of short mpegs in order to get something into Encore.
The only solution I’ve come up with is to render everything to a tiff sequence, then create a new project that might (I hope) be more successful in rendering the mpeg. However, the tiff render estimates that it will take 20 to 30 hours.
Can anyone point me to a procedure to diagnose and fix the reason why AE refuses to complete the render? OR is there a way I can speed up the tiff render? OR can someone suggest a strategy that keeps my source images at a decent quality in order to get the best possible image on SD DVD?
Thanks

PNG is faster, smaller, better, its Tiff’s upgrade.
below link will talk about hdv problems and crash problems. search box for opengl crashes toohttps://forums.creativecow.net/thread/2/939983#940003

Thanks for your response. I had found the troubleshooting (https://generalspecialist.com/2007/02/troubleshooting-after-effects-7.asp) suggested in this thread. The very first suggestion – importing the project, seem to have improved the stability / failing that I was experiencing. However, it has taken 8.5 hours to do 8 minutes of the 19 minute composition! Aside from going out and buying 8 GB of RAM ($CDN300) in order to make full use of my quad core processor, are there any obvious ways to speed up the render?

Since this is the first major project of this type I’ve done, I’m experiencing Stock Problem #1 to which your Stock Answer #1 is the correct response. I should also note that Stock Good Production Habits #1 would have been useful at the time I was acquiring the footage (monitoring all three cameras with real external monitors, having the right number and kind of lights, etc.). They would have eliminated a lot of the visual massaging necessary in AE – however, these habits all cost way more than my budget.
Given the above, I take it that my best strategy from the start would have been png image sequences and the judicious use of proxies?
Thanks

On AE concerning HDV and .mpg?
Seem like every other post is about this these days…
Or how about get HDV to GO AWAY

We are in the process of giving up, as human nature seems unstoppable and people can look at the posts on a board and still not want to bother to read them and will post the exact same question that is one or two posts from the top of the forum. Hence, Dave LaRonde’s Stock Answer #1 and it’s near unassailable position as the most posted answer in the history of the COW.
We have been thinking of writing a “postus interruptus” (to butcher the Latin) script that sees certain words and highjacks the post before it goes up and will offer certain common questions and answers.
That is the only thing that would work.
Best regards,
