30i and 30 fps mjpeg in same project

[SCDVD]

I shot an event with an HV-30 set to record 30i SD. I used a stationary tripod mounted Canon SD900 Digital Elph to shoot cut-to footage. It records 640 x 480 at 30 fps in MJPEG. Are there any things that I need to do in order to use these two sources in the same project in Vegas pro 8? The output will be MPEG-2 that will be used to author a DVD.

Evening.

Well, both videos would have to be the same format: Codec, Resolution, and Frame Rate
Audio, you can always mux into the finished video later unless you change the frame rate of either videos.

Interlace vs. Progressive:
MPEG, its ok to mix Interlace and Progressive as long there is provision to modify the flag during encoding. With AVI you have more leaway and can mix either in a final avi project. I do know that in TMPGenc you can modify the flag anywhere inside the encoding project and both I/P can live together. I don't know about Vegas setup however.

You can encode them both as interlaced. The only consequence is a little blurring of the chroma channels in the progressive source.

I tried it and it worked fine. There isn't much motion so there isn't any noticeable effect from interlacing the progressive MJPEG video. Most of the footage is from the HV-30. I'm just using the MJPEG footage as a cut-to when the other camera was moving or blocked by someone walking in front of the camera etc. The other thing that I have to deal with is the small black border on each side of the MJPEG footage. 640 X 480 isn't the same size as the DV footage from the HV-30. Is cropping a little off the top and bottom of the MJPEG footage the best way to deal with this?

if it were me i'd encode the mjpeg to a lossless codec at 720x480 before importing into the project. lagarith is what i usually try first. you will need to crop a little or the aspect ratio may get out of whack.
