The best format to upload your videofiles in are MP4 25 or 30 frames pr. second, 1280 * 720 resolution (16:9) and aprx. 3 mbit/sec. A file in this specification should have a filesize aprx. 25mb pr. minut video.
If you just started using PodcastMachine we recommend you to test your video source file by uploading a small subset of the file - for example a 10 seconds clip, before uploading the full file. In this way you are absolutely sure that you get the expected result from your source file when uploading it to PodcastMachine. You can always delete the test-uploads. After uploading your file and it becomes "ready" - if you dont see you episode under build-a-player - the format you uploaded was not recognized by PodcastMachine. If this happens then try to upload in another format. Newer versions of Windows Media and newer versions of FLV are currently unsupported.
The maximum filesize you can upload is 1GB.

Could we possibly get the encoding details on the different formats?
Well, it's a bit tricky to give you all the formats, because there are so many - and all formats are available in 4:3, 16:9 and Cinema 2.35:1, and depends on the sourcematerial you upload. For example we can't make a HD version from a 320*240 sourceclip :-) But here are some general guidelines.
VIDEO:
Ipod format is up to 640*480 1500kb mp4 h264
Windows Media is 640*480 1500kb wmv
AppleTV is up to 1280x720 3500kb mp4 h264
Miro is up to 1280x720 3500kb mp4 h264, or vmw
Iphone is 640*480 700kbit mp4 h264
Mobile 320*240 350kbit 3gp
And we always make a version for the flashplayer at 640*480 700kbit h264
Awesome! Thank you so much. :) One more question: are these constant bitrates, or are any of them variable?
Oh, and also I seem to be getting two variants for the flashplayer. One just says flashplayer, the other says flashplayer h264. (There are other labels for these variants like Miro or whatever, but I have everything except iPod unchecked in my settings.)
It's constant bitrate. The flashplayer also has a FLV codec version - just in case that the client browser does not have the a newer flashplugin installed. So "Flashplayer" is for older falshplugins. And "Flashplayer h264" is for the newer versions which support H264 codec.
Fantastic. Thanks a million man!
