so how do I ensure they are small enough, yet compatible with iPhone etc?
select the sequence you want to export in the timeline panel, and hit 'ctrl + m'
In the export settings dialog choose the format 'H.264'
The choose the preset 'Apple iPod, Apple iPhone Video
Then look at your estimated file size indicator at the bottom of the dialog (it's right above 'Metadata' button on my PC
The filesize should be well under 14 MB.
Hope that helps
OK, that's reduced it by quite an amount, although it is still about twice the size of a similar file on youtube, but it is now playable on an iPhone which is excellent. And it plays instantly rather than waiting for a downlaod Thanks for that.
On average, what sort of file size can I expect one minute's worth of video to be in H.264 for iPhone?
Is there any drawback to using this format for delivering video over the web?
It usually takes longer to render... that's the biggest drawback I can think of....
Dunno about the avg size, sorry.
Glad it helped,
If you choose 'mpeg4' format in the export dialog, and the Preset '3GPP 352 by 288 H.263' it will be a crap ton smaller still, while maintaining compatibility with iPhone. This will give you speed, with a substantially smaller video and file size
