![]() Sets the comparison function used for motion estimation (affects quality).For better image quality but slower encoding, you can choose either Bicubic (best for upscaling, ie scaling to a larger size), Bilinear (best for downscaling, ie scaling to a smaller size than source), Lanczos, or Bicubic spline (sharp picture). Choose the default "fast-bilinear" when speed is important. Selects the algorithm used to resize the image.Affects the resolution of macroblocks search, leading to a more precise movement detection. Activates quarter pixel motion estimation.Finds the optimal quantization for each macroblock in the PSNR vs bitrate sense. blue =this bitrate is too high, if you choose it you will not improve quality comparing to "green" values and you'll be wasting space on your disks (consider choosing another bitrate, or use a larger image size, though not larger than the source image size).Green =this bitrate is quite good, if you choose it you'll obtain good quality for the current image size Red =this bitrate is too low for the selected image size, if you choose it you'll be compressing your movie too much and the quality will not be acceptable with the current image size (consider choosing another bitrate, or use a smaller size) The suggested bitrates appear either in red, green or black color in the following dialog: Note that only MP3 audio is supported for 3-pass. log file, and the third pass will use those statistics to optimize the final video encoding (using the audio encoded in 1st pass). You will be then prompted for choosing a video bitrate amongst suggested options to fit in one or two CDs. The file will be encoded three times, the first one will encode only the audio audio and calculate the video bitrate (1st pass duration is about 1h30 on a G4 for an average movie). Encode in 3-pass mode, allowing better control on movie final size.The "Clear" button at the bottom of the Progress window cancels finished processes from the list.When a process is done, a "reveal in Finder" button appears to locate the encoded file in the Finder.A done or fail sound effect is played at the end of each process. ![]() Waiting processes can be started manually with the "Start now" button (don't run concurrenty multiple 3-pass encodings).The processes are queued in the list and will start as soon as the preceding process finish or fails.The output is colorized in red for errors, orange for warnings and blue for useful information. The "more info" button opens a window for advanced users including the process output.The Progress window list includes, for each process, a progress bar, a cancel button and a "more info" button.If it is not enabled (default) then encoding will take place in the "ffmpegX Progress" Cocoa ObjC window. If the option "Open Terminal window" in the Tools tab is enabled, actual encoding will take place in a terminal window. You may also save a custom preset to a file by using the "File > Save Preset" menu. After choosing a preset, you may further customize it by clicking the "video", "audio" and "options" tabs. A preset defines many relevant settings with a single click. The right-"LCD" display allow to select a destination format from a list of presets.In mpeg-2 encoding, is encoded after the whole video has been encoded, so the video will preview silent. Click this button to preview the converted movie while it's still encoding.If you don't specify it, a destination location is automatically selected by ffmpegX in the same folder as the source file. movie.avi, movie.mpg, or audio.mp3 (however, if you're encoding with the mpeg2enc engine there is no need to specify a file extension). Click this button to choose a name and location for the converted file including the proper file extension, eg.When playing a non-encryped VIDEO_TS folder, title, chapter and angle controls from the video tab will also take effect. ![]()
