~Tak tahu , maka mencari untuk tahu.. tapi macam kurang tepat aje dengan perkembangan semasa.. apa itu iFRAME?..

iFrame is a digital video format, developed by Apple. It is based on existing industry standards, such as AVC/H.264, AAC and QuickTime, and can be used with compatible Mac and PC applications.[1]
The format has been created to simplify video editing. Traditionally, Apple video editing tools like Final Cut Pro and iMovie have required conversion of video from its original format into intermediate format such as ProRes 422 or AIC for editing. With iFrame such conversion is no longer needed starting from iMovie '09.[1]
Many non-Apple editing tools do not require conversion of video from source to intermediate format, instead allowing to edit the original videos directly.

iFrame video and audio is encoded using lossy compression. Only intraframe compression is enabled; every frame is a stand-alone i-frame. Video is encoded with the AVC/H.264 compression scheme. Audio is encoded with the AAC codec. The compressed audio and video are multiplexed into a QuickTime file.
To reduce data rate and hardware requirements, video frame has size of 960 horizontal by 540 vertical pixels with pixel aspect ratio of 1:1, which results in 16:9 display aspect ratio. Progressive scanning at 30 or 25 frames per second reduces data rate even further, but may result in increased “judder” when compared to the traditional rate of 60 or 50 pictures per second used for television broadcast.
The video sub-sampling, bit-depth, and the video, audio and aggregate bit-rates are not yet publicly known.
