source video


result use qtgmc bob + srestore 23.976 fps



the text line become blur.

[rrats]

Either it's the qtgmc or 720p resizing. Send script and sample of the original sourcr

[Selur]

sample is the most important part, since the source might not be interlaced at all but just encoded as MBAFF to be blu-ray standard conform,...
(or it might be a wild mix of progressive, interlaced and telecined content,...)

[jagabo]

Of course the text becomes blurry. There's barely enough resolution at 1920x1080 to make it legible. Reducing the frame size to 1280x720 is only going to make it worse.

[exekutive]

Exactly what jagabo is saying. This has nothing to do with encoding. I simply resized your source image by 66.6% (1080->720) and it came out "weird".
