With your video options set you're ready to encode. For more efficient (ie lower bitrate) encoding you may want to go as low as 96. Since you'll only be getting 2 channel output, regardless of the number of channels in the original audio track, you shouldn't need to set the Bitrate any higher than 256. Although it doesn't have a lot of settings that you're likely to change, you may want to visit the adjust the Audio tab to adujst the Bitrate. Audio Bitrate TMPGEnc Xpress has its own AAC audio encoder, which will automatically be used for AVC encoding.
Make sure to adjust Maximum bitrate as necessary.Ħ. Maximum bitrate will be unaffected, except to ensure it's no lower than the average. Once you click the OK button the Average bitrate will be transferred to your video settings. Remember that size and percentage both include audio, while bitrate is specific to the video. If you set the Flie size instead the bitrate required bitrate and percentage of the selected media will be calculated instead. For example, setting the bitrate will tell you how large the output file will be and what percentage of the selected media will be filled. Regardless of which one you set, the others will be automatically calculated. Depending on your requirements you can set Video bitrate, File size, or % of the media capacity manually. Use the Calculator button to open the Bitrate Calculator The Output dropdown list provides a range of different media sizes ranging from 128MB flash memory or memory sticks to dual layer HD DVDs. The Bitrate Calculator TMPGEnc Xpress can calculate the bitrate required for a particular output size (including audio) for you. In many cases it's better to make it at least twice as high, and in many cases it should be several times the average.ĥ. As a rule it's a good idea to set Maximum bitrate to at least 1000kbps more than Average bitrate.
Increasing the maximum will allow more complex scenes to use a much higher bitrate, and significantly simpler scenes to be encoded with as little waste as possible. While Average bitrate determines the size of the encoded video, Maximum bitrate determines just how variable it really is. Bitrate For variable bitrate encoding you need to consider both the Average bitrate and Maximum bitrate. This will result in a predictable output size and better quality than 1 pass Variable Bitrate or either Constant Quality option. Rate Control Mode In most cases Rate Control Mode should be set to 2 pass Variable Bitrate. NTSC DVDs from film sources should be encoded at 23.976fps, while video (whether interlaced or deinterlaced) should use 29.97fps. Framerate will generally be determined by whether the source is an NTSC (generally North American) or PAL disc.
If it's from a true interlaced source (a video camera rather than film) and you're not deinterlacing should use a Progressive option instead. If your DVD source originated as film, as most do, this should always be set to one of the Progressive options. Framerate In reality the Framerate setting includes both the rate and structure (progressive or interlaced) of your output file. For example, while a widescreen (16:9) DVD will have a resolution of 720x480 (NTSC) or 720x576 (PAL), when resized for the 1:1 (square) pixels of a computer monitor neither would be correct. When using this setting you'll need to make sure the resolution matches the video's aspect ratio. If you're reducing the resolution you'll probably want to set Aspect Ratio to Pixel 1:1. If you're keeping the DVD's resolution you need to make sure Aspect Ratio matches your source, meaning Display 4:3for fullscreen or Display 16:9 for widescreen. Size and Aspect Ratio The settings for Size (resolution) and Aspect Ratio always need to be considered together. Although this results in fewer optiions to tweak than more complex programs like MeGUI or AutoMKV, it also means you don't have to spend hours researching a bunch of stuff you probably don't want to mess with just to figure out which settings you should set manually.ġ. TMPGEnc Xpress uses a fairly simple interface to set AVC encoder settings. Select MPEG-4 file output on the left side of the dialog and MPEG-4 AVC from the dropdown list on the right. Fortunately you can keep most default settings and just set a few options that vary from one encode to another.įormat Clicking the Format button will automatically bring up the Output format selection dialog. This will allow you to begin the process of setting output options. Once you return to the main TMPGEnc Xpress window you'll need to select the Format button at the top.
