scaling looks terrible-help!
Hi,
I’m trying to create a video for YouTube, and I’m curious if anyone has ever experimented with the project settings in order to create a project that has the same screen dimensions, frame rate, etc as a YouTube video.
I ask because I recorded a video (an interview) from a tripod, and it’s very plain looking if I just use the original footage….instead I want to pan and zoom within the image throughout the interview…but when I create a project with the standard NTSC settings, and then scale my footage, the zooming is terrible….very blocky and grainy….yuck!!
I’m hoping there is a better way to do this using a more appropriate project setting, so that when I can scale OUTward rather than having to zoom INward…some zooming in is not working well for me.
Thanks for any suggestions!!–Jason

Panning/scanning is the worst enemy of video compression…every pixels is changing with every frame and there are not enough bits of data to do both smooth and clear.
Shoot for the web with no pans and no transitions. -
Hi Mike-
I just started reading about compression, and I now understand that this makes things difficult.
I was hoping there was some trick???

2 pass variable bitrate encoding with a high “max” can improve high motion scenes without clogging network pipes.

Not sure what others are actually finding with YouTube, but you can do exactly what you want. YouTube recommends a 320×240 video. That is one quarter of a full DV frame. Which means you can use one quarter of the image to fill a full frame (say a person’s eye) and then “zoom” out to the full, actual frame ( the face) which will in reality be scaled down to 50%. Your image will be totally clear. No artefacts at all in the “zoomed in” size since the video is not actually scaled up, and scaling down in PPro works quite well. Pan as required.
Use a custom, Video for Windows setting, chose 320×240, 1 PAR and rock and roll. Export as a mp4 QT movie, playing with quality as required to get a file just under 100 mb – mono sound save a whole lot. Stay away from WMF unless you cant get QT to create a file less than 100 mb.
Since YouTube recompresses what you send them anyway, you don’t care about, and cant control, bandwidth at all – just the 100 mb maximum file size. What you send as 7 minute, 100 mb QT file comes back as about 20 mb flv file.
