About Image Sequences

CINELERRA-GG supports image sequences with both decoding and encoding.

CINELERRA-GG by default uses ffmpeg as encoding/decoding engine but we can disable it to have the specific internal engine available. See sec:ffmpeg_early_probe_explanation on how to switch between engines. With the internal engine we can create and load sequences of OpenEXR; PNG; TIFF; TGA; GIF; PPM and JPEG. There is also support for DPX sequences, but only in read and without rendering presets. With ffmpeg we can create and load DPX sequences or create a custom preset for any kind of image. Using these formats results in great timeline efficiency and high video quality at the cost of taking up a lot of space because they are uncompressed (or with lossless compression). By rendering, you will get as many still images as there are frames in the project, plus a file-list (or TOC) that indexes the images. A good practice is to create a folder to contain the images (for example /tmp/img_seq/) and then open the rendering window in CINELERRA-GG and set a serial and increasing number as the name (for example: /tmp/img_seq/image %05d.png). image is a generic name chosen at will; % creates a progressive sequence of distinct images; 05d indicates how many digits the image number will be, in this case 5 digits to go from 00000 to 99999. Once we have our folder of images, if we want to import it in a project just load the file-list, which includes the link to all the files of the sequence. To learn more about using and creating a preset with ffmpeg of an image sequence, see sec:ffmpeg_image2_streams and/or sec:image_sequence_creation.
