Video is Crazy!!! Very strange problem with FourCC!!

[Cauptain]

Hello guys,

I have a very strange problem.

Fact : Video was recorded using Camtasia and UT VIDEO CODEC using ULY2 option (YUV422)

Problem: My players not works (WMC-HC, POTPLAYER, KMPLAYER), No Virtualdub (gray screen) or VideoLAN (han) or Smplayer (No play).

Can anyone give me a light?

With UT CODEC installed - Video FourCC is=CLJR ( look here: )
Without UT CODEC installed - Video FourCC is= ULY2

How to solve this?

64 bit vs 32 bit? VFW vs Directshow?

[Cauptain]

UT Video codes are VFW codecs. You need DirectShow codecs to play in media players.

I have DS codecs Jagabo but no way. Other files using UT VIDEO works, but the dimension is 720p or 480p.

I try various camtasia records...All files have same problem (412x320x60fps). Camtasia no report error.

Tks for reply.



PS: I will upload file.

My windows is 64 bits. I have install both versions.

Camtasia is 32bits software.

There's definitely something unusual about that file. Although it claims to be ULY2 encoded (YUV 4:2:2) it contains a color palette index (normally used for 256 color or greyscale images). I suspect the graphics card was running in a 256 color mode and Camtasia encoded the video incorrectly.

Hello Jagabo,

Excuse my delay in responding.

I sent your reply for Camtasia staff helper and I'm waiting for a response.

Thank you for your help.

Actually, it's not a palette index. But there's an extra "indx" which I don't usually see in AVI files.
