CELLING  Good software, easy to use but too expensive.  
(Version 1.6)

TOURNESOL  Excellent application, and the support is more than great. The best subtitle application for the Mac no doubt!  
(Version 1.3)

TOURNESOL  Works rather well, but using the blu-ray beta plugin with DVD Studio pro STL (spruce) subtitles does not convert the tags for italic formatting into something useful, but instead puts the tags in the png files, and that is not very good. Please fix.  
(Version 1.2.2.12)

D-MAC  Functionality and import/export options are quite good.

However, the GUI design (or lack thereof) makes this application difficult to use and requires multiple repetitive steps to do simple tasks. The interface has many inconsistencies, controls/icons that are cluttered and too small, and a lack of overall consistency and usability.

If the (one-person shop) developer would consult a good GUI designer, and observe actual user workflow, then overhaul the interface, this application could become the top tool of its kind.

For efficient entry of subtitle or caption text, there are many better choices under US$100.

Additionally, there is no user manual, on-line help, or video tutorials (or other training). When feedback is given to the developer, he reacts quite defensively and does seem to appreciate or respect user input. All this for an application that costs nearly US$400.  
(Version 1.2.2.10)

PTFIGG  This is a must have tool for media producers. It is packed with intuitive features, and it offers stability, impeccable design, and value. It's really a stellar achievement.  
(Version 1.2.1.6)

ERRJOTT  The best subtitler and metadata tool.

Easy to use and full of useful features.  
(Version 1.1.6)
