Weird Colors

[bigbangnet]

Hello guys,

I noticed some wierd color issue when capturing game footage with Dxtory. As seen in my video that I have here in this thread, the issue is that the colors are messed up for some moments then disapears. I don't know whats going on ?!? I'm using x264vfw for the codec. Any help would be appreciated

That's not a color palette problem. It's a data corruption problem. Either the file was damaged after capture, or some of the data didn't make it to the file.

I did used lagarith lossless so I wonder if I should use that codec again. The problem is just the size since I capture at 1080p. Perhaps theres a setting in the x264vfw that I don't know ?

Use UT Video Codec for lossless. Or x264vfw with the ultrafast preset.

Here are the settings that I use.

Oh and I gave UT codec a try and now I see lots of options for the codec to choose in my list (yup, I'm a bit new at this stuff) care to give me pointers - UTvideo Pro, UTvideo RGB, UTvideo RGBa, UTvideo YUV420 and so on and on

I can say for sure that your sample wasn't encoded by x264vfw. If you want help than you should provide correct sample and not re-encoded one with another codec.

That's about as fast as it will get.

Pick the one that matches the capture. Use RGB for 24 bit RGB capture, RGBA for 32 bit RGB capture.

Uhh what ? I go in dxtory and I used x264vfw (it creates a .avi file at this point). Then once I got my video, I edit it in Sony vegas pro and render it. Even before I render it, I just play it when I'm inside Sony Vegas pro and I see the "corrupted" data. As far as I'm concerned I don't re-encode it multiple times.

You re-encoded it by vegas (instead of simple stream copy cut in virtualdub) and this way removed all information how it was encoded by x264vfw. So it is not possible to say now if it was x264vfw fault, vegas decoder fault or if it was dxtory fault in first place. btw I hope you don't overclock your PC because it can be also PC stability problem.

So what do I need to do in order to reduce or remove that corrupted effect ? Do I need to record in lossless instead ? That way I could go in vegas and encode it ? This could be considered that I encoded it 1 time since lossless is not encoded ? Do I have that right ?

Sorry, but I give up. You can do what ever you want. I only said that when doing such bug reports you should provide (upload) source sample and not the re-encoded sample where artifacts already encoded in video itself and so meaningless for analyze (it is only useful to look what you see but not for analyze why you see it).
