| If I try to change a framerate, then audio is out of sync? Is just one possible way to fix that problem is video stream without audio to change, and then put them back together? Will it works? And one more question- can I change framesize with VirtualDub? |

| When you change the framerate you are changing the length of the video stream, stretching the audio stream to match the video streams' length may work. Ex. Save WAV, open the WAV in an audio editor use one of time compress/expand features to change the length, mux the wav back into the avi. You can use the built-in resize filter to change the video frame size. |

For the resize, in VirtualDub under Video -> Filters. Add the resize filter and enter resolution you want. For the audio editor, I'm sorry but I use Sound Forge and don't have Cool Edit (my trial ran out). |
