TMPGEnc Settings (Advanced)

The Setting dialog box allows you to alter the encoder parameters. It includes the following tabs:



Advanced

Video source type

Choose the appropriate setting to match the source material:

Setting Meaning
Non-interlaced (progressive) Computer animations, some DV camcorders and Films are progressive sources.
Interlace Anything grabbed from TV or VCR will be interlaced. Most DV camcorders produce interlace video.

Field order

When interlaced source material is used this option selects which field of each video frame is presented first. Choose from:

Top field first (field A)
Bottom field first (field B)

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:

Setting Meaning
1:1 VGA Use the source as encoded. If your source is computer generated, or generated for viewing on computer screen (e.g. many streaming video formats) use this setting.
4:3 525 line (NTSC) Source video was captured from NTSC in normal (720x480) resolution.

Use this for video captured from a live broadcast in the USA, Canada or Japan.

4:3 525 line (NTSC, 704x480) Source video was captured from NTSC in CCIR 601 (704x480) resolution. See below for an explanation of why not to use this setting when creating SVCDs.

Use this setting for creating VCDs from a live broadcast in the USA, Canada or Japan.

4:3 625 line (PAL) Source video was captured from PAL in normal (720x576) resolution.

Use this for video captured from a live broadcast in Europe, South America, Austrailia, Asia, Africa and India.

4:3 625 line (PAL, 704x576) Source video was captured from PAL in CCIR 601 (704x576) resolution. See below for an explanation of why not to use this setting when creating SVCDs.

Use this for creating VCDs from video captured from a live broadcast in Europe, South America, Austrailia, Asia, Africa and India.

16:9 525 line (NTSC) Source video was captured from NTSC in normal resolution, but was intended for viewing at 16:9 aspect ratio.

Use this for converting from an NTSC resolution Anamorphic widescreen DVD.

16:9 625 line (PAL) Source video was captured from PAL in normal resolution, but was intended for viewing at 16:9 aspect ratio.

Use this for converting from a PAL resolution Anamorphic widescreen DVD.

4:3 Display Source is 4:3 video that is not standard NTSC or PAL resolution.
16:9 Display Source is 16:9 video that is not standard NTSC or PAL resolution.
2.11:1 Display Source is 2.11:1 (cinema format) video.

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

Setting Meaning
Centre The video will be displayed in the centre of the screen. Aspect ratio will not be preserved.
Centre (keep aspect ratio) The video will be displayed in the centre of the screen. Aspect ratio will be preserved.
Centre (custom size) Allows a custom size window to be defined, allowing black bars surrounding the video.
Full screen The video is expanded horizontally and vertically to fill the screen.
Full screen (keep aspect ratio) The video is expanded to fill the screen, but aspect ratio is preserved. Black bars will be added if aspect ratios do not match.
Full screen (keep aspect ratio 2) The video is expanded to fill the screen, but aspect ratio is preserved. Black bars will be added if aspect ratios do not match.
No margin (keep aspect ratio) The video is expanded to fill the screen. The edges (left/right or top/bottom) of the video might be chopped to prevent black bars being added.

Filters

Various filters are available that have an effect on the encoding process.

Source Range

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.

Inverse Telecine

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.

Ghost reduction

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.

Noise reduction

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.

Sharpen edge

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.

Deinterlace

This filter allows interlace to be removed from the video sequence.

Clip Frame

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.

3:2 pulldown

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.
