New iphone4
Okay so I got an iphone4 with HD video, not bad for a phone, but of course being an Apple product, it doesn’t just drop straight into Vegas or anything else that’s not Apple! DO I really need to transcode each and every file or is there a codec that will let me play and edit my iphone footage on Vegas?

Had the same situation and it motivated me to upgrade from Vegas 8 to 9. Vegas 9 takes those files nicely where Vegas 8 won’t recognize them. But seems like you need a system with lots of guts to work with those files.

The iPhone 4 records AVC (aka, H.264, MPEG-4 Part 10) video in 1280×720/30p at about 10Mb/s. This is fairly comparable to video recorded by some of the “Flip” (and Flip-style) pocket camcorders, but less than half the complexity of a “real” AVCHD camcorder.
Most AVC camcorders record using the AVCHD standard, which means you get AVC video at up to 24Mb/s, AC-3 audio, all wrapped up in an MPEG-2 transport stream (eg, same container format as HDV). Some variations include Sanyo’s models, which record AVC video and AAC audio in an MP4 wrapper – the standard MPEG-4 file format. Apple’s recording in the Quicktime file format, which is a well established Apple standard (much as Microsoft has AVI), also quite similar to .MP4.
Anyway, you can’t edit this in older versions of Vegas, you can probably re-mux it to MP4, which will work, without the need to re-encode — much faster, no quality loss. You need Quicktime installed on your system, most likely. Anyway, try YAMB (Yet Another MP4 Box GUI), which can find here: https://yamb.unite-video.com. This is pretty good at re-muxing to proper MP4. I was messing around with a Sanyo camcorder last year, which produced slightly flawed MP4 files that could crash Vegas. Re-muxing them in YAMB (which uses the command-line MP4Box tool for its main work) made them work find in Vegas.
If you find iPhone 4 video to be taxing on your system, you’ll want to upgrade that PC before jumping into using an AVCHD camcorder.

I actually have yamb but hadn’t used it. Just for kicks, I tried to drop a few of the iPhone generated quicktime files in it to see what it would do. Seemed like it was going to take days to do whatever it does. Does that sound right to you? Was I doing something wrong? Definitely didn’t see anything that indicated “much faster”
So yamb, if I do it right, will remux to new MP4 files that I can drop on the Vegas 9 timeline and edit without any crashes like the problems I had with the origonal iPhone 4 video files?
