Importing images sequences into Cinelerra is done via list files. A
list file is nothing but a text file with a specific format containing
absolute paths to every frame in the sequence plus additional
information like image resolution, fileformat and sequence framerate.
Weren't we using this a list, we should import every frame as a
separate clip and setting manually its duration in the timeline, which
will not only be slow as dead but would hug lot of system resources.
In the other hand we can write this lists manually, which is not
pleasent at all, specially when dealing with long paths and large
amounts of frames.
Because of all these reasons, I wrote this app which not only it
generates a list given a frame of an images sequence, but also
autodetects all related parameters with it, including number of frames,
file format and image resolution.
IMG2LIST 0.1.5 can be downloaded from here.
IMG2LIST works in LINUX and it requires full installation of Python
Besides that it needs PyGTK 2.0 or better and Glade 2.
It was succesfully tested on Mandrake Linux 10, and LiveCDs like
Ratatouille, Rollmops (http://garbure.org) and Dyne:bolic 1.4.
Even though it hasn't been tested on Windows, it might work if all
required libraries are present.
Call the program with "img2list" in a
console or using a menu. A GUI will show up as shown in Figure 1.
1. Interfaz de IMG2LIST 0.1.3
We should locate in our hard disk a frame belonging to the desired
sequence using the "..." button next to "Carpeta" ("Folder").
This sequence should be a TGA, JPEG, TIFF or PNG images sequence, which
formats supported by Cinelerra. An images sequence is identified with
the pattern "image_filename-#####"
where "#####" is a number
representing the frame of this image in the sequence. If our files dont
fit this pattern, they will be disregarded as sequences.
Many sequences can be mixed up in the same folder: no problem. IMG2LIST should recognize which files
belong to the selected sequence and discard the rest.
Once an image file was selected, press OK in the "Cargar Secuencia"
Number of frames and filename pattern of the sequence should show up in
the main window.
If you click on "Autodetectar"
the software will grab width (W) and height
(H) information of image. Otherwise we can enter these values manually.
[*] Since 0.1.5 the autodetection of image format and resolution is
made by default. "Autodetectar" checkbox was removed.
Then we should select a filename for the list where we want to export
the data for use in Cinelerra. When done we can press "Export
Sequence" to write a list file with all the sequence information. In
the status bar int he main window a message will show up reporting
We can also enter a value for FPS,
the sequence framerate in frames per second.
We can go on generating other list files for all images sequences we
need and then click on "Leave" to leave. If IMG2LIST is
called from a console, we can have a grasp of the processed data.
