Hi folks,
I've recently bought a digital camera (Canon Powershot S400) which takes MJPEG video, and I quickly found out that the videos do not play correctly on Win2k. Well that's not entirely true. They play correctly in Quicktime, but they play three times faster in Media Player and other applications. No problem, I thought, I'll just use VirtualDub to convert them to a more conventional format like DivX or Xvid.
AVIcodec 1.1.0.4 identifies the video as:
15.0 fps, 320*240 (4:3), MJPG = Motion JPEG
When I try using VirtualDub 1.5.9, the same problem happens, however. The file is correctly identified as 15.0fps, but it plays far too quickly. So does the resultant output, no matter what format I convert it into. To make matters even more convoluted, various other people can play the video correctly, so I'm at a loss.
Any idea why the video and its compressed counterparts play too quickly? I'd appreciate any help. I put a sample clip online in various formats you can take a look at (http://www.runelands.net/tmp/). If I'm writing too fast in the clip, it means you're getting the same behaviour I am.
Thanks in advance for any suggestions, hope I'm not too offtopic,
Cheers, mers
