Description

TMV’s are native movie files for the RT render engine. TMV’s are generated during the Import process when used with image sequences such as a TGA or PNG stream.

Using TMV files

  • TMV files are tOG movie files
  • TMV files are similar to quicktime movies and they can carry an alpha (transparency) channel
  • TMV files are created in Swift from image sequences, typically a targa stream or png sequence

When do you use TMV files?

The choices for the template author are simply between whether to use a movie - such as a Quicktime movie file - or a tmv file. There are both advantages and disadvantages to using TMV's, but the correct choice can make a significant difference.

Consider these questions before deciding to use TMV files

Will my image sequence be updated dynamically or regularly?
Use conversion to movie file

Is my image sequence full frame hd and longer than 150 frames?
Use conversion to movie file

Is my full frame HD image sequence longer than 100 frames?
Use conversion to movie file

Is my image sequence sequence intended to loop?
Use conversion to movie file

Is my image sequence smaller than full frame?
Consider conversion to tmv

Is my image sequence less than 100 frames and ¼ of HD resolution?
Consider conversion to tmv

About TMV files

TMV files are stored in RAM and loaded at start-up of the project. Voluminous and multiple TMV files in a project will subtract the equivalent memory resources from the renderer.

Video files are not the same in this respect: Video files stream directly from disk and take up very little RAM resource on start up.
