To convert rectangular pixel PAL 720x576 DV to square pixel image you should scale to 788x576, then optionally crop it with 10 pixels from both sides so that the final image is 768x576. RE: Picture box, square and rectangular pixels? dilettante (MIS) 29 Mar 14 10:33 Question is is it possible to format in some way a picture box in rectangular pixels and save them? I get a reasonable result setting the final picture box to 1024x576 (16x9) but the picture is slightly grainy with artifacts a bit like thumbnails when you magnify them because I don't have the correct number of pixels. I load the picture to be converted to a hidden picture box, crop or magnify it, then PaintPicture this to a second hidden picture box of exactly the desired pixels, then save as a bmp while previewing it on a smaller image box with stretch - true.Ĭonverting to 640x480 or 720x570 for 3x4 SD (standard resolution) and to 1900x1080 for full HD is perfect because they uses square pixels but when I try to convert to 720x576 wide screen (which is what all PAL SD material is these days) the quality is lower because the video editor has to reconvert it to rectangular pixels because 720x576 is not 16x9 Also the Adobe video editor doesn't crash or run out of resources! The BMP quality of the final result is just as good in every way as the original jpg when viewed on a computer monitor and noticeably better on the final DVD or Blue Ray compared with letting the video editor do the conversion. I wrote a little program to quickly crop and convert any pixel size JPG taken on a 3x4 digital still camera to widescreen 16x9 BMP's of exactly the same pixel as my home videos.If you do this, stills integrate with the video without the problems you often get trying to mix different resolution or compression material in video editing and it is such a pain converting each one exactly in Photoshop.
