Please don’t think of this as just a deinterlacer — it does a great many things, it does them very, very well, and it does them completely FREE. I encourage you to download and try it, as it’s superior to many such shareware and commercial tools.

Over the years, I have evaluated more than 40 different video manipulation programs — both multi-function apps and those dedicated to specific tasks — and JES Deinterlacer is the very best standards converter (PAL > NTSC or NTSC > PAL, etc.) and deinterlacer I’ve ever used (fast too). It has been around for at least 11 years, is frequently updated, and the developer is very responsive, a real pro.

Here are some of JES Deinterlacer’s capabilities (from its manual):

◆ Deinterlace digital movies (various ways), change field dominance, and reinterlace;
◆ Standards conversion (scale and change frame rate, for example PALNTSC), and inverse telecine (NTSC -> film);
◆ Crop, shift, and add edge;
◆ Simple color correction;
◆ Reduce noise (using a temporal filter), removing jaggies, deblocking;
◆ Change encoding (gamma, video range/full range, compressor);
◆ Fast/slow motion, reverse movie, progressive in/out;
◆ Lossless M-JPEG field handling;
◆ Flipping video vertically and horizontally;
◆ Copy/implement track geometry, both classical (track scaling, etc.) and new (image description extensions for pixel aspect ratio and clean aperture).

This developer also offers a few other great, free video applications, including JES Video Cleaner (, which does a superb job of reducing noise, removing logos, averaging two movies, removing cross-luma and brightness variations, etc.

BTW, I don’t work for and have never met the developer. I’m just a big fan of great video freeware and shareware, and I’ve been using this one for nearly a decade.

Never encountered this little useful app! Works perfect for NTSC movies.

Great job !

One of the very best video utilities available — free or otherwise. Many don't know this, but in addition to being the best deinterlacer, it's especially good at standards conversion (converting video from PAL to NTSC and vice-verse), better than all but the most expensive commercial apps (like Compressor, Episode Pro or Squeeze). The developer updates it frequently, helpful, and is very open to suggestion. A major must-have.

Waow! I've found nothing else for slowing down a movie as accurately and fast! (even if it's not its main purpose, it was exactly what I was searching)
N.B.: my goal was to find the steps in a salsa dance movie... ;-)

Interesting Tool!
I would need it to resize Video (MPEG, progessive) from my digoicam.
Resize works but without filtering noise reduction.
But i see that noise reduction is only selectable if Video input is interlaced?!
Doesnt such noice reducuction or other filters cant be used on progressive video ?
(Bug or it is so planned / not possible to add filters for progessive video)

This has to be the very best app available for doing the things it does, even if it is free. Aces.

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!

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

This software only seems to convert from NTSC to PAL and not the other way?

Why would you think that? If your input file is PAL then you would check the NTSC box to convert it to that standard. If your input file is NTSC then you would check the PAL box to convert it to that standard (if you're playing it outside of the US, Canada or Japan).

Found this solution in "./JES":

"In case of startup problems it often helps to delete the plist in home/library/preferences."

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.

The author says OS 10.4 is required. That is why it won't work with Panther.
