ABOUT Colorspaces

I just want to ask which is better, using ConvertToYV12 or ConvertToYV24?

I'm currently using this in my psp encoding..

DirectshowSource()...... .ConvertToRGB(matrix="rec709")
video=Spline64Resize(x,y).7
video=ConvertToYV12(video, matrix="rec709")
video=UNfilter(video, -2, -2)


BTW i used ConvertToRGB first because it tends to smooth the jagged edges on videos i convert but converting it back to YV12 it seems to lose some contrast but it retains the smoothness on edges made by the RGB conversion or is it because i was using the rec709 matrix. Does converting to YV24 will eliminate contrast loss, or should i just remove the rec709 matrix?

I'm currently at wok so i can't post screenshots, it something that just came up on my mind cause the movie i have now is better albeit the loss in contrast. What i'm trying to achieve is smoother edges (which i already have) and to retain the original color, say if you convert a straight movie using YV12 vs converting to RGB > YV12 (straight YV12 conversion has better colors in my opinion)

A resize is going to do a LOT more towards removing/smoothing Jagged Edges than any individual "Convert-to-Colorspace" step ever could.

But, what's your SOURCE's colorspace?

Plus, the PSP's resolution is 480x272. THAT'S NOT HD (not even SD!). So you shouldn't be using the Rec709 matrix (which was meant for HD resolution material).

hmm, ok thanks so matrix rec709 is not advisable then? btw i have a thread which shows the results of my settings above with the exception of the unfilter plugin usage, here -- https://forum.videohelp.com/threads/349291-Red-(and-other-vivid-colors)-PSP-encoding

about the colorspace of my source, can you suggest a way in checking that. i'm not really familiar about how to.

Add 'Info' to the script at the point where you want to know the colorspace.

oh, sorry i was not aware that such a thing is possible, sorry, i'll try it the next time i start my encoding. thank you.
