It also has an<br>additional setting called offset which shifts the chroma planes to the right by one or two pixels (set to 0<br>for DV source downloaded from a camcorder and set to 1 for a DV file encoded by ffmpeg). Works<br>with the YUV-8 Bit or YUVA-8 Bit color models in Cinelerra but not with any of the RGB color<br>models. Improved upsampling of the chroma planes helps with the 4:1:1 to 4:2:0 color space<br>conversion needed to create DVD compliant mpeg2 video streams. You will not get any improvements<br>if the project is being rendered back to DV format.<br></div></blockquote></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Dec 10, 2021 at 12:02 PM Andrea paz via Cin <<a href="mailto:cin@lists.cinelerra-gg.org">cin@lists.cinelerra-gg.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">So many interesting tutorials on the site you pointed out!
