"lossless" is relative ;)

if i transcode dv25 (yuv420p) to ffvhuff yuv420p it IS lossless.
if i capture a RGB screen with yuv420p it is definitive not lossless but 
you wil no ADDITIONAL have compression artefacts.
I mean always the COMPRESSION is lossless ;) like in mjpeg2000

For screen capturing in high resolution yuv420p will be enough for most 
purpuses I think.
