problem when exporting from AAE 7.0 - AVI v1.0
 

I get a problem when exporting an AVI file from AAE 7. There seems to be a file size limit. I am trying to export at 1920 x 1080 uncompressed. The file size is just over 6GB but only the first 12 seconds can be viewed of a 35 second clip. GSpot reports:

"Bad chunk in frame data: Invalid length
- Chunk:/RIFF:AVI

AVI v1.0"

It appears that I may need AVI v2.0. How do I get this?

Thanks

Andy
