I specialize in digital video software for Macintosh.
Currently I offer six pieces of freeware for download:

  1. Deinterlacer
  2. Video Cleaner
  3. Movie Tools
  4. Extensifier
  5. CopyLargeFile - for copying large files over a network
  6. Movie RAID - fastest video digitizer for early PCI AV PowerMacs
  7. Set Monitor Color
Only the first four are still actively being developed. You can discuss them in the JES forum.

Edit image description extensions

Extensions serve to encode interlace, scale (pixel aspect ratio), clipping and gamma.
This application lets you inspect and set these properties on a file, a group of files or a folder.
For professional use create presets and watch folders.

JES Extensifier v2.0.4 (528 kB)


Getting better color on your monitor

My first three monitors had the 'blues' on arrival: they were far too blue in gray areas. The Cinema monitors are much better but I still like to reduce blue gamma a little (settings 1.9-1.9-2.1).

To fix this problem on Mac OS 10.4, download this tiny app:

JES Set Monitor Color v1.1.1 (84 kB)


JES CopyLargeFile v1.4 (72 kB) (click link to download)

Features: allows you to copy files larger than 2 GB over a network under Mac OS 9 or X (HFS+ disk only).
Other features: suspend/resume, can split files into equal parts, options to set the file part size and the copy buffer size, crash resistent (resumes where it was interrupted).
Multitasking: copies several files simultaneously as individual projects.
New version posted February 2004.

JES Movie RAID v0.6 (168 kB) (click link to download)

The only Mac video digitizer that can handle TV data rates!
Digitizes uncompressed full size video (576x720 or 480x640) at full frame rate.
For PowerMac 7500/7600/8500/8600 only.

Two hours of NTSC video will easily fit on two 70 GB 10.000rpm UW SCSI disks.

Movie RAID comes with a configuring utility which lets you set the disks to save to (up to 4) and set a timer for unattended recording (multiple recordings possible, programmed up to 23 hours ahead of time).

Movie RAID digitizes both audio and video.

You can digitize only top half or bottom half of the frames if you like. Alternatively, digitize odd or even field. The two can easily be recombined.

After digitizing you have the option to have the video frame durations regularized (for example 100 on time scale 2997). This can prevent loss of frames in editing applications or in conversion to DV or DVD. The audio will be resampled to stay in sync if necessary. Sample rate options are 22.05 kHz, 44,1 kHz, 32 kHz and 48 kHz.
Version 0.5 preserves sync between audio and video even after hours of recording (assuming steady drift).

The program works with Mac OS 9 and QuickTime 4.1.1 or higher.

This software comes close to unleashing the full digitizing power of the early PCI AV PowerMacs!

As goodies I have included the Regularize utility and the SetMovieDataRefs utility.
The former is the stand-alone version of the regularize frames feature.
The latter is for fixing data references which may get broken if you copy a reference movie and its data files to another disk.

v0.6 update: posted November 2005.
No longer maintained.
