It seems that there is no firm background information included in FCP 4.5 on what sort of collection of settings you need to have given a certain way you've obtained a file and a way you'd like to output a file. It doesn't make any sense. **The Quicktime Movies in question were computer generated, NOT captured from a DV Camcorder or anything!** I have some questions regarding the following situation: SITUATION 1. I have two Quicktime Movies (.mov) that are clips I want to put in a "New Sequence". These movies were TIFF images: 1 image/frame that were concatinated (30frames/sec) in Quicktime to a .mov file. Ok. 2. When I import these files into FCP 4.5, a "Select Sequence Preset" window pops up. The following presets are my choices: (WHICH ONE DO I CHOOSE?) (a)DV NTSC (b)DV PAL (c)DV50 NTSC (d)DV50 PAL (e)DVCPRO-PAL (f)DVCPRO HD-1080i60, 720p24,p30,p60 (g)Offline RT HD(Photo JPEG)-23.98,24,25,29.97,30 (h)Offline RT NTSC(PhotoJPEG)-23.98,24 (i)Offline RT NTSCAnamorphic(Photo JPEG) (j)Offline RT PAL " " (k)Offline RT PAL(Photo JPEG) (l)Uncompressed 10bit NTSC,PAL (m)Uncompressed 8bit NTSC,PAL 3.If I don't choose one, and instead click CANCEL, I am not allowed to create a New Sequence. Is there a way around this? 4. If I choose any one of the "Sequence Presets", I can create a New Sequence, which I do. 5. When I need to Render my Sequence, I go to Sequence> Settings, and in the "Quicktime Video Settings", there are a number of ways [Codecs?], in which to render. I choose"NONE". If my aim is to export as an MPEG2 using Export> Quicktime Conversion, does it matter which Codec I choose to render my sequence as? Is "NONE" the correct setting? 6. Since the frame size of the Quicktime movies I've imported as Clips =640x480, this is the "Custom" "Frame Size" I enter in. Is this correct? 7. Then I Export>Quicktime Conversion>MPEG2 for the best quality playback given my current Frame Size=640x480, Frame Rate=30fps, PowerMacG5 1.8GHz, and DVI connection to external Video Monitor. Is this correct compression??
