ProCoder 2.0: bad resizing

[erratic]

While ProCoder 2.0 does a great NTSC Film to PAL speedup, it apparently resizes low resolution video to full D1 very poorly. Look at the picture below: to the left of the green line is what ProCoder 2 did (jaggies) and to the right you can see a much better job done by TMPGEnc. The only solution I found was using ffdshow to do the resizing (or a program you can frameserve with). It's not just an XviD or DivX problem, it also happens when resizing 352x288 MJPEG video to 704x576 for example. I wonder if other ProCoder 2 users get better results, or if ProCoder 1.5 does a better job?



EDIT: After further testing it looks like resizing with ProCoder 2 only results in jaggies when upsizing horizontally, not when upsizing vertically.

So converting NTSC 720x480 to PAL 720x576 is fine, while for example converting SVCD 480x??? to DVD 720x??? results in jaggies.

it is better to resize (as you have found), when upsizing, using an external frame server -- same issue in cce (a must there) and main concept ..

they appear to use only bi-linear resizing or bi-cubic.

even some apps that use lanzos don't do a bang up great job of it .. IrfanView and Acdcee come to mind .. IrfanView is specially bad for resizing - otherwise a great program ..

also -- your resizing ratio is incorrect - unless you want it that way ..

As far as the aspect ratio is concerned: it's anamorphic 16:9 and I left that up to ProCoder as well. But I never really convert DivX to DVD anyway. I was just experimenting and noticed those awful jaggies from ProCoder. (I use tv-out for watching DivX/XviD stuff. In that case I let ffdshow do the resizing as well, and I use Media Player Classic to make the video anamorphic. Works very well.)
