I did a 9 minutes movie about my train model set, and i woul dlike to put it on you tube.
I know we can upload *.mpg *.avi etc etc etc
but witch one works with youtube?
and what king of compression should i put?
My software enables me to save in Mpeg2, Mpeg4, divx, etc...
and when i chose the format then he asks me for the compression in a way of how many kbytes should the user see the movie... what should i chose?
should i asume that almost everybody as a conenction of 128kb at least ?
if i save the file for 256 kb will if be to slow for a 128kb ?

i think the connection type affects the total size of the movie, putting the image quality lower, the frame rate should be the same.... :hmmm:

YouTube recodes the video into flash video once you have uploaded it, and sets its own bitrate, video dimensions, and compression settings, so it doesn't matter that much how you compress the video before you upload it.

Obviously though the more you compress it before uploaded, the worse it will look once Youtube has recompressed it. There are however some guidelines you have to follow. Videos cannot be larger than 100MB, and must be 10 minutes or shorter.

YouTube also recommends using the following video and compression settings:

MPEG4 (DivX, Xvid) format
320x240 resolution
MP3 audio
30 frames per second.

But you could also use Quicktime .mov or Windows Media Format .wmv files to upload the video.

If you want some good tips, a few useful guides can be found at http://www.videomaker.com/youtube/

The problem with even considering an HD video up to 1GB in size is the length of time it would take to upload it, and for it to stream. Regardless of the percentage of people now on broadband connections, which is well over 90%, the truth is that a large percentage of these broadband connections have very poor bandwidth and struggle to even stream standard 320x240 video streams without long pauses and stuttering.

Also consider how long it would take to upload a 1GB file? Most in the UK for example now have ADSL2+, which offers up to 448Kb/s upload speed. Even at a maximum bandwidth that only works out at 56KB/s, meaning it would take 5.2 hours to upload the video!

Sticking with 320x240 resolution video makes the video much smaller in filesize, meaning it will take much less time to upload, and it can be streamed at full speed on most connections.

Considering the 1GB limit for HD video I'm not sure what the limitations are on filesize in that case, but the video still needs to be under 10 minutes in length.
