Converting mov files with Quicktime Player for iDevices

Question

I wasn't sure if should post this under iPad or here or at all as it is about coding, but it is about coding for Apple iDevices that can't display Flash, using Quicktime Player or QT Player 7 Pro:
I'm trying to add the ability for Apple iDevices that can't display tutorials I created in Flash, to see them with H.264. I read that I can simply open the original tutorial that luckily is a .mov file with Quicktime Player 10 in Snow Leopard and File > Save For Web and QT will convert to H.264 and also output several files needed to upload to your server.
But the only options are for iPhone, iPhone (cellular) and Computer. I assume an iPod would use the iPhone file, but iPad didn't exist yet.
I chose iPhone and Computer for my test. I got 2 .m4v files a .jpg, a small .mov and a .html page with the code I needed to copy/paste to my target html page.
Uploaded the files and could see the tutorial movie with my iPad fine. Using FireFox, I saw the beginning of the movie, then got the beachball. After a long wait, I tried a force quit and found that my Mac Pro was crashed too so had to hard shut down. Hate that.
Rebooted the computer. Tried accessing with Safari this time and it worked fine.
I also own Quicktime Player 7 Pro pre Snow Leopard (I'm running Snow Leopard now) and tried the conversion with it and noticed a few more config choices, like for frame rate. But the resulting code was about 29 lines of code with expected parameters versus 2 lines of code in the QT Player code which actually really surprised me. With both apps they have JavaScript references for the head tab to files on Apple's library on their site.
So.. I'm wondering why FF and my computer crash, I did output for computer as well as iPhone. And what to do for FF users and the fact that there's no specific output for iPad, am I OK just using the iPhone output since I can see the file OK on my iPad test.
Last, I've been reading about HTML5 versus Flash, but assume that what both my QT apps are outputting is HTML4. In the QT Player code there isn't even an embed tag, let alone the video tag I've read about, just a href to the exported Saved For Web .mov file, which I assume must point to the .m4v files that QT outputs and puts in the same folder as the other files, but there's no direct reference to them.
Sorry for the length, or if this isn't the place for these questions, but I do want to get this right before I convert about 20 tutorials
I wonder if I should wait until Lion and see if QT is changed to fix the FF crash and adds output for iPad?
One last thing: when you access the converted file with an iPad, first you see a jpg of the first frame with "Click to Play" in the center. When you do, you get the movie with a play triangle which you have to press to actually start the movie. But when you access the same html file with Safari, all you have to do is click the "Click to Play" and the movie starts as expected. Bug?

Answer 1

QuickTime X and QuickTime Player Pro create slightly different html code (but it all works about the same way). The "click to play" image file, a "reference" movie, multiple versions for different devices and the html code to preview the page and use as copy/paste into your Web page.
QuickTime X has fewer options than QuickTime Player Pro. The iPhone preset works just fine on the iPad.
Your Firefox crash may have been just coincidence and I doubt it was caused by the page code.
You may want to wait a while longer for the HTML 5 code because browser support is still in the learning stage and millions of PC users still use out of date browsers.
The reference movie points to the different versions of the file. The code "reads" the device and serves up the correct version for it.
I don't own an iPad but I suspect it works like my iPod Touch. All of my QuickTime files have the play "triangle" so the click to play image style page requires two clicks on it.
