video preview error when trying to render
I have reassembled an old project and am trying to render it before exporting. I get a dialogue box that says video preview error. error compiling movie. unknown error.
It’s about 37 minutes long and happened in a bunch of places. I isolated several areas where it happened and then just render only those spots and it took care of it. I have one small area left with two still photos with a push transition on each one and it still won’t render. I have copy and pasted the area, emptied the temporary folder, saved as, restarted, tried to render it a tiny bit at a time and nothing seems to work. Any thoughts?
ps-there are four pieces of media that I could not locate, but none of them are in this small area that won’t render, if you think that has anything to do with this.

Look closely at the timeline if you can find any gaps (no video), the need to be closed.
For the two stills with the push transition. Redo them in a new project and import in the project. You could do the same to the small area that does not render either. -
1st try to open the Jpegs in Photoshop and save as PNG. then in the ppro project replace them for where the jpegs are in the time line. Best way is to import the png files. Grab one and hold alt key while you drag n drop over the appropriate jpeg in the timeline, repeat this DnD with alt key for second clip.
when High res Jpeg images report errors during render it means they won’t export either.
2nd thing to do if above didn’t resolve issue… Reduce the Jpeg dimensions to best resemble your needs (if you zoom a little make the dimensions fit enough bigger than the timeline dimensions) and have the dpi at 72 not 300. 😉
Hope this helps.

Had this problem many times with 32bit XP! It rarely happens with my current setup – Core i7 950 Win7/64bit/12Gb RAM but I recently tried to import and render 750 Hi Def jpegs from a Commercials Agency in a sequence and CS4 simply refused to play. Conclusion: CS4 simply can’t handle complex stuff…period!
Two practical ways that might help your current difficulty: Firstly, instead of simply restarting your PC, switch it off completely at the mains..then switch back on after 30 secs. Don’t ask me why this helps but it has for me on many occasions.
Secondly, render the problematic sequence no more than one or two frames at a time until it is fully rendered. (ideally then export it to a mixdown to avoid future problems) I appreciate this could take some time.
As you may have guessed, this is all to do with memory and CS4’s ability (or non ability) to access it as a pseudo 64 bit lash up.
Let’s hope a native 64 bit CS5 will finally address these problems.

Thanks for all the suggestions.
