Extract Video Frames as Images

Frame selection and output settings

Frame numbers start at 1 and count the frames stored in the file. To find the frame for a moment, multiply its time in seconds by the frame rate and add 1: the moment at 12 s in a 30 fps video is frame 361. The page shows the clip's duration but not its frame rate; your video player or the file properties list it. For phone videos with a variable frame rate, the result is an approximation.

All

Saves every frame, roughly duration × frame rate images. That quickly means hundreds or thousands of files, so use it for short clips.

Range: Start frame and End frame

Saves every frame from Start frame to End frame, both included, so 361 to 390 gives 30 images. Start frame starts at 1 and End frame at the last frame of the video, so the default range covers the whole clip. Set both to the same number to save a single frame. A range past the end of the video stops at the last frame.

Every Nth: Interval

Keeps the first frame and then every Nth one: an Interval of 30 gives frames 1, 31, 61 and so on, and 1 keeps every frame. Set it to the frame rate for about one image per second. The default 2 keeps every second frame. The interval always covers the whole video; to sample only part of it, trim the clip first with Cut Video.

PNG

The default. PNG adds no compression loss, so each image keeps the full detail of the decoded frame. Videos with 10-bit color, including many HDR phone recordings, produce 16-bit PNGs. File size depends on the picture and color depth; compare the extracted images rather than assuming a fixed size order between formats. Transparency from videos with an alpha channel, such as ProRes 4444 or QuickTime Animation MOV files and transparent WebM, is kept.

JPG

Uses lossy compression and can reduce file size compared with PNG, depending on the picture and quality setting. JPG has no transparency, so transparent areas become white.

WEBP

Lossy WebP. Whether it is smaller than JPG depends on the picture and quality setting. It stays lossy even at 100 %, so choose PNG when you need exact pixels. Like PNG, it keeps transparency from videos with an alpha channel.

Quality slider (%)

The slider and number field below the format buttons, from 1 to 100 %, default 90 %. It sets the compression for JPG and WebP. Lower values mean smaller files and more visible artifacts.
