You can export to avi but if you want 720p you need to set the codec to non or something like Lagarith.
You need to set the parameters yourself.
DV avi does not go beyond SD resolution.
Let's take a closer look at this.
When you say "AVI" do you mean the old NTSC or PAL AVI that was used with the original DV cameras? If so, that codec can't handle the larger 1280X720 frame as Ann pointed out.
Why do you want to export to AVI? Because you always did in the past? Or is there another reason that would help us help you?
Is it just that you want an archive? Something you can edit again? There are ways to do that. Lagarith creates a fairly large file. Is hard drive space an issue? If not, then Lagarith is fine. There are other, more compressed codecs that you may or may not find acceptable.
My camera, for example, records an all I-Frame file at 72Mb/s and if I want to back it up, I merely export to the same all I-Frame format at the same data rate.
What does your camera record?
Once you tell us what the whole story is, we might be able to point you down the correct path.
My employer wants me to convert my videos I'm working on for him into 720p .avi format. So there isn't a codec for it? Because otherwise It'ss take 2 hours just to convert a 15 minute video for him.
The only "built-in" option allowing HD resolutions in the AVI format would be Uncompressed. It's a large file, and not commonly used.
Why exactly does he want the conversion?
Yes, why? What is he going to do with the footage? It makes a difference. He might just think that AVI is normal because it used to be but not anymore. Not now that we are shooting HD.
