What is Frame Accuracy?

MTS recordings from AVCHD camcorder are often highly compressed before stored, such a

compressed movie contains key frames and non-key frames. Key frames can be displayed

independently, while non-key frames can not be displayed without key frames. So such a

functionality to locate and display every frame correctly, no matter key frame or non-key

frame, is called frame accuracy (frame by frame). (Tip: Frame is one of the many single

photographic images in a video.)

The Advantages of Frame Accuracy:

With Frame Accuracy, you can precisely start locating and displaying on desired frame; easily

get exactly what you see or want. Without Frame Accuracy, you may lose the desire frame, or you

may get SECONDS of frames you do not want before desired one.

When you are working on a movie or short film which requires accurate frame extracting from

video stream, you need the ability to capture a precise single frame from a video file. You may

ask such question: Is it possible to capture a frame from a video in any format? The answer is

YES. And there are a lot of choices. If you're Mac user, you can use iMovie, one the best free

video editing app that comes with your computer. Yet iMovie works only with a few video

formats. Some AVCHD .mts and HD videos can not even be loaded to iMovie. Here's a new

alternative for iMovie – the Pavtube Media Magician for Mac, which supports a variety of

codecs and file types, including AVCHD, MTS, M2TS, TOD, MOD, MKV, MOV, AVI, MP4, ASF, DVD

compatible MPEG files, flash videos and even protected TiVo recordings.

(like for example 24 frames in a 1 sec video) and then allow you to delete individual or more

frames, add frames, split the video exactly between two frames you choose, join AVCHD/TOD/MOD

videos seamlessly (without encoding). If you're looking for a Mac based video editor that cuts

any video frame by frame, pick up this app.
