![]() ![]() ![]() When you found the best options for your movie, use "SAVE PRESET" in the File menu.In 3-pass mode, the first pass will run with a spinning progress indicator for about one hour before releasing control to the Progress window. 2-pass will optimize quality, 3-pass will optimize bitrate control to fit in given number of CDs. If you don't mind the extra time, decide if you want to use 2-pass or 3-pass encoding in the Options tab.The "Quarter Pixel ME" also increases quality but some hardware DivX players don't support it. Adding "B-frames" will optimize filesize as B-frames take less space. Popular settings to increase quality are "High quality", "Trellis quantization", Scaling method = "Bilinear" and ME Function = "SSE". You can use "5 sec test clip" and "Print PSNR" to compare encoding speed and signal/noise quality to help you choose the best quality/speed settings. As a general rule, the more option you use, the slower the encoding and the better the quality. If you want high quality, turn on some of the advanced options in the Options tab.Set which will extract the subtitles to a VobSub file (this will let you playback the DivX movie with subtitles).After selecting the subtitle track, you can use "Preview" to preview the subtitles.button, it is scanned for available audio tracks and they are displayed in the Audio track popup menu, including details on the file format (mpeg1 or AC3) and the language). (When selecting a VIDEO_TS folder with the Open. Select the audio track from the audio track popup menu.If you prefer to keep the source AC3 track, select AC3 (in that case, the source AC3 will be copied 'as is' without any re-encoding, so make sure to set 448 as audio bitrate when using the bitrate calculator). Go to the Audio tab to select audio options.Select title/chapter/angle to be encoded as you require.The calculator takes into account the audio and its bitrate. This is because the encoder will react differently to simple scenes (ie talking heads) and to complex scenes (ie detailed images in high motion) and depending from the quantizer settings, this variation in the content may lead to variations in the bitrate. Please understand that the bitrate calculator only gives a forecast, and pretty much like weather forecasts, it can be wrong.you should never encode by using an image size greater than the source image size.if the resulting horizontal image size is lower than 480 you will obtain less than SVCD quality, and if it is lower than 240 you will obtain less than VCD quality, so in such cases you should consider to increase the media size (eg use two CDs instead of a single one).Don't try to fit too much minutes in a small CD size, or the opposite, few minutes in a big size, and note the following:.After clicking "Auto", the calculator has set a 933 kbit/s bitrate and an image size of 624x256. In this example, we set a movie duration of 91 minutes and ask to fit the resulting.It will calculate both video bitrate and image size for optimal image quality. For example, 1 CD of 80 min mode-1 (always choose mode-1 or data-cd for. ![]() First enter the duration of your source movie and define the media where you're going to store the resulting movie. We're now going to use the calculator to set the video bitrate.The crop area will show as a white hairline rectangle. You may also click "Preview" to preview the crop area again after changing manually the crop values. Autocrop will also launch a preview movie to show the crop area.You may need to change this checkpoint if it contains black images. The Autocrop analysis is done at the "Start from: 00:30 min:sec" point to avoid to analyze black images at the beginning. This button also sets the default image size. Go to the "Filters" tab and click "Autocrop" to automatically calculate crop values in order to cut away black bars from the source.Normally this is 2.35:1 for a feature movie, 16:9 for widescreen video and 4:3 for standard video. In the "Video" tab, set "Autosize" to the movie aspect ratio.The codec used by this preset is "libavc" which is one of the best existing mpeg-4 codecs in terms of image quality. Click on the "Target format" pulldown menu and choose DivX mencoder.
