STORMCHILD  This is an excellent tool for cleaning up video. In addition to deinterlacing -- which it does very well -- it can do deblocking as well. I've been very happy with the results so far. And it's free!

"H"  This is fantastic, I got stuck with a commercial PAL/NTSC conversion which has a lot of hand-held camera work and animated photos. When authored to DVD there was too much judder. I compared doing the conversion using usual MAC software and a commercial PC product and this is the one gave far superior results, I will use it from now on. A Big thank- you to the developer

GTMP  Just done one test and I'm already a fan. Why do we continue to suffer the slings and arrows of the many inadequacies of Quicktime! Thank you for filling the gaps Mac leaves behind.

LAINE  Unknown error #1407 - fatal error message appears at launch.

Error code lookup reveals "Expected a folder and got a file instead".

µø˜˚´¥  I second what Dr. Zoom says - this app is a worthy addition to any video pro's toolbox.

One great feature is what JES calls "Double Movie Duration" which basicaly turns each field into a frame. This almost always produces better slow motion than interpolating frames.

MARK BURTON  I have been using this app for a long time and it has remained one of the best tools around. Developed with a deep understanding of the processes, constantly updated and improved by a developer. 5 star all the way.

JOHN D  GREAT software

Very simple to use, considering how hard to understand deinterlacing can be...

And very fast and efficient too.

A must for every video amateur

ANONYMOUS  Have been using this tool for a few weeks to fix an issue with some clips from our Avid. The De-Interlace processing is fast and top quality. Great job Jan, keep up the good work.

MARC ROBIN  4 out of 6 .Mov files created with Imovie 4 makes Jes Deinterlacer 2.6.5 crashes ! I cannot understand the reasons. I have imported them into Imovie HD without any problems but it doesn't change the mov. file ( quicktime ) 6 the problem stays the same.

CHARLIE  I just tried converting PAL->DV-NTSC with no sucess. After the program opens the progress window, it immediatly crashes. No error except apple's standard "do you want to send a bug report?" I have to trash the preferences every time b/c JES opens right up to the same project, and promptly crashes again. I'm using 10.3.9. I really wish I could use this program, i've found no other that converts PAL->NTSC without smearing.
