exporting / 16x9 question

I searched tons of threads in the forums but couldn't find an answer to my question-

I'm trying to export a music video I shot on HVX for the web. Specifically, I'm trying to get a 20MB version because my client only allows a max of 20MB files to be uploaded.

SO-

I exported a little fragment to see if i'm on the right track:

QT Conversion
Compression: H.264
Quality: High
Bitrate: 900 kbits/sec
Dimensions: 320x240


The duration was 6 seconds and it came out at 753KB. So I think I'm close but my main problem is that it comes out squeezed every time with no letterbox.

I tried checking the preserve aspect ratio button but then it did letterbox on the sides!

I'm drowning..

Any life preservers out there..?
 
That's a pretty high bitrate for 320x240, you can probably do the popular 640x360 with 0.9Mbps H.264 without any problems. Also make sure that you are using a compressed audio format like AAC or IMA.

If you have 16x9 video and select output dimensions that are 16x9 using square pixels, it shouldn't letterbox. However, 320x240 is obviously not 16x9, so that may have something to do with it.
 
First of all, thanks.

-The audio is ACC.
-I only used that bitrate cause I read someone else was using that (not smart)
-I probably can't use the size you offered (even though I tried it and it was cool) cause I need a 20MB version to upload to the web.
-My clients have a 20MB limit to the sizes uploaded to their site. And the vid is 3:20 length.

Two questions- what will the 640x360 size do at home on my 4x3 Sony TV? Letterbox?

And how do I force a letterbox on. I would like it to be viewed with it on every TV. Widescreen and 4x3. that could be an idiotic statement so go easy on me.
 
How long is your video? The only thing that determines the final file size is bitrate times duration -- output dimensions and framerate don't factor into it. Thus, if you have 5 minutes of video to fit into 20MB, you have to get it down to 4MB/minute, or just under 700Kbps.

I routinely encode 640x360 H.264 video at 500Kbps, and it looks pretty good. The extra 200Kbps would all go towards more image detail, so you should have no trouble meeting the 20MB file size limit using a 5 minute video. Again, I don't know how long your particular video is, but few music videos would be longer than that.

How a 16x9 video displays on a TV depends on how you output it. For instance, a 16x9 DVD played on a 4x3 TV should be letterboxed automatically by the DVD player if it is told that the TV is 4x3. What is your setup?
 
In compressor, costumize your output setup. Select the 320x240 setup, for example, then look for the top right box on your display where all the settings are and search for pixel aspect ratio and screen size. I believe that you can select "compy to 16/9" or something like that. I had the same problem, but this solved it.
