when do i use this,
do i preform Selectively Prerender Video every time before i save to the computer?
when should i prerender?
.
and when i save this for a DVD, or for a you tube page is their a recommended template.?

l when i saved a 40secound video its size came to 500mbs,

other then putting it into the windows movie maker and saving it again,
can i reduce the size.?

one last question.

i have 50 cuts, lets say i change the chroma keyer to one of my cuts,
and i like it, can i get the other 49 to adjust all together. without doing each one manually.

You never *have* to prerender; it's never required. The only time i ever prerender is if i have a complex transition or effect and i want to watch it in real-time in the preview window, and generally i'm doing a RAM prerender of a couple of seconds of the timeline. Other than that, i never prerender anything.

DVDs are always MPEG2. You can either render the video to MPEG2 (use the NTSC DVD Architect or PAL DVD Architect templates) and then render the audio separately to WAV or AC3, or you can render to a DV .avi file and have DVD Architect convert it to MPEG2 for you.

I haven't done youtube so i'll let more experience people handle that one.

Rendered file size is determined solely by the duration and the bitrate. Use a lower bitrate and the file will be smaller. These are adjustable in the custom options for most formats.

I'm not sure about Vegas Studio, but in the full version you can select an event, press Ctrl-C to copy it, right-mouse-button click on the next and choose select events to end, then right-mouse-button click again and choose paste event attributes. This copies all effect information to all the rest of the events. It also copies pan/crop settings and any other effect settings that you didn't want to copy, so this may be of limited use even if the studio version has it.

Alternatively, you could put all the chroma-keyed events on their own separate track and add the chroma-keyer effect to the track header instead of to the individual events. This way any settings are applied to all events in that track all at once.
