Compression |
| Fast integer |
Fast integer method. This method
is the fastest but considerably less accurate than the other two; its use is not
recommended if high quality is a concern. |
| Integer |
Slow but accurate integer
algorithm. |
| Float |
Floating-point method. This
method is slightly more accurate than the 'slow' integer method. |
| MMX |
If grayed MMX is not detected.
If checked, MMX optimizations are used.MMX
optimizations :
- Inverse DCT and dequantization on fast integer and integer
methods.
- Upsampling, color conversion and merged upsampling and color
conversion for all methods (even with fancy upsampling).
|
If grayed MMX is not detected.
If checked, MMX optimizations are used.MMX
optimizations :
- Forward DCT management and quantization on fast integer and
integer methods.
|
| Fancy upsampling |
If checked, do careful upsampling of chroma
components. If unchecked,a faster but sloppier method is used. The visual impact of
the sloppier method is often very small. |

| 3DNow! |
N/A |
If grayed 3DNow! is not detected.
If checked, 3DNow! optimizations are used.3DNow!
optimizations :
- Forward DCT on float method.
|
| Enable codec |
If checked, the codec is enabled,
if not it is disabled. |
| User FourCC |
If checked, the text in the edit
box is used as the default FourCC for both compression and decompression.
- Matrox Rainbow Runner users should check it and type dmb1 in
the edit box if nescessary.
|
| Enabled |
If checked, decompression is enabled, if not
the codec reject every query for decompression. |
If checked, compression is enabled, if not the
codec reject every query for compression. |
| Support Interleave |
Apply only if height is more than 288. If checked, decompress and display 2 interleaced fields per frame.
If unchecked decompress and display only the first field
(odd lines). Odd lines are duplicated to fill even lines. |
Apply only if height is more than 288. If
checked, compress 2 fields per frame (2 JPEG images are stored, one per field, for each
frame).
If unchecked compress and srore only the
first field. |
| Invert Field order |
Odd lines become even lines and
even lines becomes odd lines. |
