TMPGEnc Settings (Advanced)
The Setting dialog box allows you to alter the encoder parameters. It includes the following tabs:
Video source type
Choose the appropriate setting to match the source material:
When interlaced source material is used this option selects which field of each video frame is presented first. Choose from:
If your source material comes from a DV camcorder, set this to "Bottom field first". If in doubt, try using "bottom field first". If you find your video flickers on playback it may be that you have selected the wrong option here.
It is possible to determine the field order before encoding by selecting one and then opening the deinterlace filter window. Once there move the slider across to a part of the source with motion in it and press the scroll button. If the image is jerky then the wrong field order is selected.
Source aspect ratio
This sets the width to height ratio of the source material. If your source is actually larger or smaller that the setting it will be cropped or padded with black pixels to fit. Use one of the following options:
If you are creating an SVCD from 704x480 or 704x576 source video you'll need to ensure that an 8 pixel padding region is added each side of the video before encoding. The easiest way of ensuring this is to set the source aspect ratio to 720x480 or 720x576. This is required to maintain the aspect ratio of the video when scaled to 480 pixel wide resolution. The 480 pixel wide video is scaled back to 720 pixels by the decoder.
Video arrange method
Various filters are available that have an effect on the encoding process.
This filter allows you to specify a start and end video frame for encoding. Also a time delay offset to the audio track can be added, allowing lip synchronisation to be achieved.
This setting undoes 3:2 pulldown. If you have NTSC format video (30 fps) from a film source This will allow the original film framerate (24 fps) to be recovered.
Ghosting is an artifact introduced on analogue signals when a reflection or duplicate transmission path is present. It produces a "ghost" image shifted slightly left or right of the main image. Enable this filter to reduce the ghost image.
Analogue video signals are subject to noise. If you tune your TV to a weak station you'll see a lot of noise on the picture. If you have source material with visible noise, try this filter out.
Noisy source material not only looks bad, but the encoder will spend precious bits faithfully encoding the noise! Using this filter should help reduce the bit requirements of the encoder.
If you have a noise free picture this filter may introduce some blurring in the video, so disable it.
If your source material is blurred or out of focus, this filter may help to bring some better definition to the image by sharpening the horizontal and vertical edges. Don't expect too much though.
This filter can also be used to soften edges by specifying negative filter values.
Simple colour correction
This filter can apply simple colour correction to you video sequence, allowing you to specify brightness, contrast, gamma, red and blue adjustments.
Custom colour correction
This filter allows complex colour adjustments. Several different filters can be applied in sequence. Try this filter if you cannot achieve the desired results using the simple colour correction filter.
This filter allows interlace to be removed from the video sequence.
This filter allows a clipping region to be specified on the original source video. As a result only a portion of the video will be encoded with a fixed border round the edge.
Converts from film framerate (24fps) to NTSC video framerate (30fps).
Do not (do) frame rate conversion
This prevents frame rate conversion. If the source material framerate does not match one of the MPEG frame rates, the video and audio will not be synchronised.
Allows audio to be adjusted
