When Buzz converts a video, say an avi, to upload to YouTube what is the resolution and format of the uloaded video? Is it avi, wmv, mp4 etc?
YouTube accepts a number of formats and I have read that YouTube converts them to 320x240. The directions say that uploading in mp4 or wmv is best.
I don't understand why the YouTube display window is 425X355 when there doesn't seem to be a software that will save at that resolution. Does Buzz save at that resolution? Can I control how Buzz converts a file?

I want my YouTube videos to display in the best quality. Can Buzz do this better than if I use VideoWave 8 to convert and save a file as 320X240 wmv and uploading it to youtube. I mean does Buzz optimize the avi file for best display on YouTube or is Buzz just all about making the upload process itself automated?
Thanks Dale

Good questions. Buzz converts the file to WMV before upload. It doesn't upscale the video, but it uses a table to calculate the bitrate that is appropriate for the size of the video to get the best possible upload time while maintaining quality.

Video size = bitrate (bps)
320 x 240 = 400000
320 x 288 = 420000
352 x 288 = 450000
352 x 240 = 410000
384 x 216 = 450000
480 x 270 = 700000
640 x 480 = 1000000
768 x 432 = 1500000

Does this help?

Yes, Thank you that is very helpful.
Is there any way to see or save the Buzz wmv that is going to be uploaded to YouTube before it goes? How can I tell what the final size will be so it isn't bigger than the 100MB YouTube limit? Does Buzz warn you if the compressed wmv will be too big?

Buzz will warn you if the file is going to be too big, but we do have some issues if you select multiple upload targets. Version 2 will be smarter about handling this. You can grab the file before upload if you look in the My Videos/Roxio Buzz folder during the transcode, but an easier way might be to select "Export" from the Project menu, which creates a new WMV file from your edited video.
