combine two videos that have different fps.

[shh1cd]

Hello video experts,
I am in a very tricky situation and I am curious about whether there is a good solution for it.
Here is a scenario.
I have a customer who would like to videotape our storyteller with two video cameras.
One is panasonic AVCHD and the other is Sony HD.

When I captured the video, I got one MTS file from Panasonic.
And it is 1280 by 720 size with 59.94 fps.
The other file I got from Sony was 1440 by 1080 with 29.97 fps.
On top of that, I have external audios that have to be sinked with two videos eventually.
The customer wants to intercede two video clips and sink the auido from external sound files.

How should I approach this project?
Should I change the 59.94 fps to 29.97fps first? or should I sink the audio first before I edit out the video clip?
Any help would be appreciated.

Sony Vegas. That's the short answer.

First, you define your final output, and that becomes your project settings. Any media imported will be rendered to the project settings.

However, you do need to make the actual edits that define what the final product is.

AFA the mechanics of it, everyone has their own workflow, but the idea is to conform everything to the "highest and best" use. Upsample the soft material rather than downsample good, but shoot for a target in the middle, like 720p30.

Do your slomo's and fX as separate entities, and prerender them.

You've got 2 things to think about here: Changing the resolution (up or down), and changing the framerate/interlacing (up or down). As budwzr said, need to decide what your target is, though I would NEVER recommend 720p30 as it isn't considered a standard format. Downsampling/downrezzing will preserve more of the "sharpness" of the higher original than upsampling the lower original. IIWY, I'd pick a "standard" format for compatibility's sake. That will determine which one to give priority and which one to adjust (will be at least one, could be both).
For this kind of processing, I'd do the conversion first in AVISynth/Virtualdub, as you can tweak the settings much more optimally. Then you'd import 2 "similar" clips into Vegas for real editing (and syncing as well - that's where you should be doing that anyway).
This is probably a preferred order: Convert -> Load in editor (V1+V2+A3+A4) -> Sync all 4 full clips -> edit/composite -> add FX/Titles -> Export Master

Thank you for your help, budwzr and Cornucopia,

I forgot to mention that I am using Adobe Premiere pro for editing the video clips. My target output is flv file for the web. With that being so, I have two questions,

To budwzr,
Which initial projectsettings should I use? Are you suggesting HDV 720p30?

To Cornucopia,
It looks like you suggest me to convert the files first before importing them. Is there any tutorial for using AVISynth/Virtualdub? I never use AVISynth or Virtualdub before. Any help would be greatly appreciated.

Yes, HDV 720p30 seems to accomodate your mixed media bag, and plays well everywhere.

I'm not a movie maker, I mostly do compositing, so Scott would know more than me, as far as end-to-end editing.

As far as fps, this is accomplished by the software, but you do need to look out for blurring and/or juddering. I'm not familiar with Premiere though, and how to make the optimal settings.

P.S. The Panasonic "AVCHD" files may only be 30p. It depends on the sensor.
