Separating Rendering from Encoding? Editing Rendering Encoding A Format 1 Video high quality Render encoded: Render each time a new encoding is required B Format 1 Render and encode: Format 2 render once and encode Video high quality Video high quality later in multiple formats Format 3 Format 4 … Format N. 16 2007 Adobe Systems Incorporated.

Video formats for Editing 1) Uncompressed formats 2) Lossless compression Avi or Mov uncompressed QT: Animation codec 100%   Tiff, Targa, PSD sequence Tiff sequence with LZW   3) Perceptively loss-less 4) Lossy compression PAL / NTSC: DV  QT: Motion Jpg or Photo Jpg  Mpeg, all families  Jpg sequence  FLV  17 2007 Adobe Systems Incorporated.

Tips & Tricks Rename .mov and .mp4 in .flv 1. In QuikTime always set prepare for 2. streaming Test and fine tune encoding settings 3. on few seconds selection Force key frame with cue point 4. Render once, encode in multiple 5. formats Animation codec at 100% = lossless! 6. Deinterlace not necessary if reducing 7. the height to half size or smaller If clients give you DVD-Video and 8. they are the only available source just rename .vob in .mpg and open it in Premiere. 18 2007 Adobe Systems Incorporated.

Tricky concepts 1) codec vs containers 2) Frame rate vs keyframe Codec = H.264, MP3, ACC, VP6… FPS = frames per seconds   Container = FLV, MOV, M4V, MP4V,  3GP, 3G Keyframe = full uncompressed  image used as reference by codec Keyframe interval = frames  between keyframes 3) Frame size vs file size Frames size = pixel dimension of a  single frame File size = KB or MB dimension of the  video file on your disk 19 2007 Adobe Systems Incorporated.
