Even more H.264 questions – please:)
OK, I have asked questions before and have tested the H.264 and compared to QT and MP$ and completely understand that it does look the best while still keeping a good tradeoff with file size. However in Compressor I can’t figure out how to get H.264 to let me have the full video. I must be missing something somewhere but I have raw HD footage from my Canon XH-A1 that comes in as 1440 x 1080. H.264 only allows 320 x 240 (under webcast), 854 x 480, 428 x 240, 640 x 360 and so forth but not a complete match so any way I use it i am losing information that I really do not want to lose. I would really like it to play on an iPhone and use some even multiple or fraction of my original footage like 720 x 480 or 480 x 360. However all the options to change those settings in the Inspector are grayed out and will not let me change them. What am I doing wrong?
Thanks

I use MPEGStreamclip to encode using H.264.
I prefer 640X360 resolution when converting HD clips for Web.
And I find the results very satisfying.Pradip Patil

You must be missing some options…or you aren’t looking in the right place for them.
Under OTHER WORKFLOWS>WEB>STREAMING>QT 7 you have a lot more options. And then in the Inspector, in the GEOMETRY tab, you can adjust the dimensions to be what you want.

[George Mizzell] ” However all the options to change those settings in the Inspector are grayed out and will not let me change them.”
You need to duplicate the presets in order to modify them.And this is a Basic Forum question.
Before working with any application, you should have a look to the manual.

Thanks but under my QT 7 tab I have 5 choices and on all of them the geometry tab has all options grayed out. If I create a new setting using the + drop down I get the choice of H.264 for Apple devices, Blu Ray and DVD Studio Pro. That allows me to change some parameters but the geometry tab only allows me to change the cropping – not the dimensions.
Thanks – still searching

I have read the manual and a mere technical description of codes is totally worthless without knowing how and when to apply which codec for which desired outcome. Apple left that out of their manuals. I know what I want – I don’t know how to get rid of the grayed out selections. I posted here because I found several other H.264 discussions in progress and read them and they were interesting but still left me with my question.

George,
I’m talking about your comment about “the options are grayed out”.
Thats nothing related with codecs, but about how to use Compressor.
That is on the manual.

George,
Use the Preset that lives here if you want control of your dimensions…
Apple/Formats/Quicktime/Quicktime H.264.
The presets you are selecting for iPhone/iPod, etc only allow dimensions and encoding settings supported by the device. You cannot encode full 1080 for playback on an iPhone (at least up to the 3GS iPhone…don’t know about iPhone 4)
Note, that the preset I am instructing you to use will allow encoding at the full original HD size of your original, but will not be playable on an iPhone. That may not be what you want.
If you want playback on an iPhone, use the dimensions available in the iPhone preset. They are not cropping any info. H264 for iPhone uses square pixels…thats why the dimensions are not what you are expecting. Your camera does not shoot square pixels…its shooting HDV…its an anamorphic format…its equivalent in square pixels would be 1920 x 1080…which is not supported on iPhone. You want to downscale to 16:9 (640 x 360).
