    I apologize this is all very new/confusing still to me but is this possible:
    Using VirtualDub
    original 30FPS video(from digicam) - section cut/converted to 22.956FPS to be in sync w/ audio(music)
    but now I want to add that section back to the original video but it will not let me since it is 30FPS. I still want the normal part and the slow part - is this possible?
    If so - how? I was reading about Re-Interleaving 24fps Film with 3-2 pulldown and progressive frames but I do not think that applies to this.
    Any help would be greatly appreciated!

  2. You could use the "frame rate conversion" function of VirtualDub to convert the frame rate of one clip to match the other. This keeps the same running time so audio sync won't be a problem. But the result will playback a little jerky because frames will be duplicated or deleted in the process.

    If you are going to make a DVD you can compress both to progressive MPEG 2 at their current frame rate then use DGPulldown to add pulldown flags that instruct the DVD player how to create 59.97 fieds per second for standard definition NTSC TV.

    It wouldn't work for 30fps video: 59.94 in fields means 29.97 in frames and input framerate should be 2/3 to 1 of output to get pulldown working.

    Yes, I assumed his 30 fps video was really 29.97. If not, he can just convert to 29.97 fps using VirtualDub or whatever. Dropping 1 frame out of every 1001 will hardly be noticable.

    I believe it actually is 30FPS - http://www.dpreview.com/news/0504/05042201canons2is.asp#specs
    and I am not making a dvd - rather I am just going to compress for the web. I will take a look at the "frame rate conversion" jagabo - thank you!

    ok I'm approaching this all w/ a different method now - this topic can be closed - I was actually making this more complicated than they were! lol sorry

  8. Just for the record: those two frame rates are not equal. One is 30.00030000300003... and the other is 30.0003. One solution to this would be to use AVIFrate to change both to exactly 30.
