Does Frame Accuracy matter in video quality?
It depends. To answer this question, we may first discuss some basic ideas.
What is Frame Accuracy?
Movies are often digitally compressed before stored. There are key frames and non-key frames in compressed movies. Non-key frames can NOT be displayed without key frames, while key frames can be displayed INDEPENDENTLY. The functionality to locate and display each frame correctly, no matter key or non-key, is called Frame Accuracy. (tip: for each picture in the movie, we call it a frame)
Why we need Frame Accuracy?
Without Frame Accuracy, you can not start displaying on desired frame; the desired frame may be LOST, or you may got SECONDS of frames you do not want before desired one.
WYSIWYG, also spelled as What You See Is What You Get, has long been a standard demand for modern softwares. We will surely take this as a normal requirement. Hard to imagine, when a user defined a cut point on the time line, but the output is 3 seconds away from that point.
Some professional Frame Accurate video editors happily capture and store footage in H.264 AVCHD MPEG2 formats, but transcode it into something friendlier for editing.
Then what if you want to trim an video without re-encoding in order to preserve the original video with no quality loss and save time wasting in re-encoding?
Smart Rendering is an ability to edit video file avoiding decoding/coding of each video frame. As decoding/coding of each frame takes considerable amount of time, using of this ability will give you fantastic increase of file editing speed. Besides, this method of video editing saves 100% of original video and audio quality. Since H.264 AVCHD MPEG2 is lossy, any re-encoding to H.264 AVCHD MPEG2 will reduce the quality of the video.
With the smart rendering of FameRing technology to ensure minimum video re-encoding, the export of one hour TV show will take only a few minutes, since most of the video content will be copied from the original recording into the new file without modification.
