I'm trying to convert a 1080i HDV from FC using Quicktime conversion into a 16x9 movie for the web.
Doesn't QT support this.
I tried the h264 with preserve aspect checked & unchecked, letterbox or crop and it came out squeezed every time. I couldn't get it to work in Compressor either.
I can however make a wmv in 16x9 no problem.

What frame size(s) did you use?
Remember that HDV is 1440x1080 non-square pixels - true HD is 1920x1080 or 1280x720 square pixels. Confusingly both 1440x1080 and 1920x1080 are 16:9.
Suggested 16:9 web frame sizes are:
1280x720
1024x576
768x432
512x288
256x144
All of the above are equally divisible by 16 which is a rule of thumb when encoding to formats like Flash and H.264.
Remember that you should also be deinterlacing your interlaced HDV video.
Quicktime and compressor (and of course FCP) are all easy capable of doing all of the above. However you'll get the best results out of compressor, as it's a dedicated encoding application.

Don't forget the JVC HD-110 is HDV and is 1280x720. It's true, and it's not true HD. :-)

Of course, but the OP was referring to 1080 vertical resolution. Indeed some Sony cameras are actually only 960x1080
As such, in my world, only device of actual (rather than interpolated) 1280x720 and 1920x1080 are true HD (ignoring data & frame rates, colour subsampling and bit depth for now ;-) )
In the world of ACVHD you'll get messed around much more with what the manufactures definition of 'HD' really is.
The sad thing is that so many consumers have been fooled into thinking they are buying into the word of HD, not only with cameras but especially with displays. Just imagine if you bought a 42in plasma for several thousand $$ or ££ a few years ago that was only capable of 853x480. Even now, only the very latest sets are capable of true 1920x1080p24/50/60. I get mad when I see 'specialist' outlets selling sets marked as FullHD or TrueHD when they have a native panel resolution of only 1280x768 (allied to lousy scaling and deinterlacing chipsets).
Wow, I've been ranting...apologies!

He was, but *you* brought up "true HD" and 1280x720. I was simply correcting that point. :-)
And I agree with your "rant" about HDTV. It's amazing going into a BestBuy and listening to the ignorance (or even lies) of the salespeople about resolution and what HD means.

sorry I've been out of town over the weekend.
I am using FC 6.0.04 my camera is Sony Z1U and I captured HD 1440 x 1080. I have tried various combos of settings and it is still queezed.
I did however import the footage into a 720P FC project and export using QT conversion
broadband high, checked aspect 16x9, deinterlace, set to fit, and it works perfectly. I get the video in a 16x9 web format.
when I do this from the 1080i project it is squeezed.
I tried pasting the footage into a 1080P pro res project and it works.
Is this the work around I have to do to make it work?

Re: 16x9 from Quicktime for web by Daniel Low on Aug 18, 2008 at 9:26:27 pm
It's a workaround but not one you should have to use.
Are you explicitly setting a frame size in compressor as I suggested?
Using QT conversion will not give you as good results as using compressor, properly. However if you don't know your way around compressor then you might have to settle with the workaround.
When you import your 1440x1080 onto either a 720p or 1080i project, all FCP is doing is interpreting the footage as either 1280x720 or 1920x1080, which is effectively what you are doing when you you export to a true 16:9 frame size as I mentioned before.

I was still trying to work from QT conversion. I just got into Compressor and found the place where your telling me about to make the adjustments and save it as a custom preset. I have success!
