Need Colorspace Utility

[mlong30]

Hi All,

Is there a utility that will tell me what my currently colorspace is in a video? I want to know if my video is RGB24, RBG32 etc.. I want it to be more detail. I'm not really a fan of Gspot, since I found out that its been reporting false field order.


Thanks!

Out of curiosity, do you mean the colorspace used for the encoding or the colorspace being used during playback/rendering.

e.g., DV's native colorspace is YUV 4:1:1 (NTSC) or 4:2:0 (PAL) but DV decoders will offer up RGB24, RGB32, UYVY etc etc.

(Our DV decoder has an option to display the current decoded colorspace on the video, for example).

I'm using NTSC.

Yes, I mean both colorspace used for encoding, and the colorspace being used for playback.

The reason why I'm asking is because I'm trying to use NeatVideo/VirtualDub to cleanup a DV uncompress file. Then import the file into Sony Vegas to add lower thirds then export out to Mainconcept/CCE Basic for DVD. When I tried this, I noticed my video quality was terrible. So, I'm thinking it has to do with the number of times the colorspace has changed.

When I skipped the SonyVegas edit, it looked great, but I need to add the lower thirds. So I figured if I could keep up with the colorspace change, hopefully I won't loose as much quality.

You can give our Enosoft Enhanced DV Decoder a whirl to try to see what colorspaces are being used.

If you look at the How-To on burning timecode, you'll see screenshots that show the colorspace info.
