Supported File Formats

There are basically 2 kinds of supported file formats, native and ffmpeg. With the addition of ffmpeg, the majority of the supported file formats you will be using comes via this thirdparty package. There are hundreds of ffmpeg file format and codec combinations. This set of possibilities includes qt (quicktime), avi (audio-video interleave), mp4, mp3, mov, mpeg, m2ts, ts, wmv, mts, mpg, flv, mkv, webm, webp, ProRes and many more.

The other supported formats, referred to as native, include the following: AC3, Apple/SGI AIFF, Sun/NeXT AU, FLAC , Microsoft WAV, Raw DV and PCM, MPEG Audio and Video.

Still Images:

JPEG/EXR/GIF/PNG/PPM/TGA/TIFF. Note: even if CINELERRA-GG outputs fp32, exr/tiff values there are normalized to 0-1.0f.

MPEG Files:

What is an MPEG file? A very common file format is MPEG because it works with many cameras and televisions. Mpeg2 video, an elementary codec stream for mpeg files, is the most common format. To read this format you need to decode the mpeg stream. You can read and write mpeg natively. Mpeg video encoding is done separately from mpeg audio encoding when using the native file format, meaning that 2 passes are required and then they have to be muxed together. However, if using ffmpeg it is rendered in only 1 pass. DVD uses MPEG as does NTSC and Pal.
