 I've heard lots of talk about using Virtualdub to convert NTSC AVI's to PAL. Can this be done without noticing jerkiness in the video?
I've tried doing this before on many other programs simply by re-saving my files with 25 instead of 30 frames. But the result is terrible, *very* choppy motion because the frames aren't 'pulled-down' or interpolated, but rather cut off.
My question is:
Which feature(s) in Virtualdub allows you to decently reduce framerates (NTSC->PAL) without noticing motion artifacts or jerkiness? And... Is it
possible to keep the audio in sync after this conversion process?
If so... would the quality of a standalone converter outperform VDub?

Try using avisynth instead for this task, I guess you'll get better results. |

There is a lot more to converting PAL <> NTSC than just changing the framerate. There is also the matter of resizing the video while also dealing with the fact that the video has interlaced fields. Neither Virtual Dub, nor AVISynth, are going to provide acceptable results. The Canopus Procoder software does a very good job of converting formats. However, unlike Virtual Dub, it isn't free.

Sorry, but with Avisynth you can actually perform all the tasks involved with converting from NTSC to PAL and viceversa.
There are many useful scripts at Doom9 forum. |
