Importing videos on the iPad

Question

Has anyone figured out how to add video from a desktop computer to a keynote presentation?
For example, I have some video files in my camera, and when I use the camera kit to move over all the media in my camera to my iPad, those videos go into the 'photos' app on the iPad.
When you try to add a video to keynote, it only searches in the photos folder for images and video, so I can easily add video that I uploaded from my camera to keynote, which is good.
However, if you do all the proper conversions of a media file on the desktop (I.e. Changing avi to mp4) and then drag over these video files to the iPad, they only show up in the 'Movies' app, and not in the photos app where you need them to be selectable in Keynote.
How can I put videos in the 'photos' app to make them accessible by keynote?
(note, I have tried uploading videos to my camera from my desktop first, and then using the camera connection kit, but that doesn't work since my camera don't allow adding of files to the SD card.)

Answer 1

.mov file import to iPhoto - how I did it
create album in iphoto
import .mov to library first rename it thus...img_1234.mov (numbers don't matter, avoid 0000)
add the .mov file to the new album 
in itunes iphone sync options, in photos, find album and tick it AND on that page tick INCLUDE VIDEOS
in "summary", tick "include only ticked songs and videos" (dunno if this last particular step is really necessary but it doesn't hurt)
(disclosure: I actually sync very little media content with iphone, don't sync with icloud so this is a per-project thing and reset to original when accopmplished)
Sync phone
Now in iMovie, your clip will be pickable
I recommend you use it and output/save your complete iMovie asap
Go back to iTunes on Mac and de-check include videos and the album you checked in "photos"
Sync again, it will be gone from phone
One other little iMovie1.3 thing: if you are using any of the trailer formats - they require video, not stills, so plan ahead...have something you want to use in your trailer that acts like a still? video a few seconds of it with your phone (or import as above) first
