Better encoding of complex interlaced content?

[2Bdecided]

This is typical of what I'm trying to encode...

http://rapidshare.de/files/40272580/compare_resize1_DV2.avi.html

...though most shots have better colour and exposure. The four thin vertical lines were added to help a comparison, and stressed my usual encoders out greatly. They won't be there in the finished footage, but provide a good test case for now.

I'm using CBR or near CBR at ~8Mbps.

I've tried:

QuEnc - horrible quality on this.
TMPGEnc plus 2.5 - OK, but introduces noise.
HC Enc - slightly better, but introduces noise.


In HC Enc, I've tried MPEG and fox1 matrices (can't see much difference), CQ really low (e.g. 1.0) to hit the bitrate max (tried 8000 and 9000 - 9000 is fractionally better, but obviously the bitrate is higher).

Is there a way of encoding this clip without adding visible noise? It's got to go on a DVD. I only need to fit one hour on the DVD.

Would ProCoder help? Not that I can afford it at the moment, but it would be interesting to know how much of an improvement that kind of money buys.

Cheers,
David.

Try encoding with vbr, set AQ to 0, set the bias to 30, and using a high bitrate matrix, but more times than not, matrixes reallly dont make any difference. HC will probably be your best bet here. Hc seems to handle interlace content the best. I heard that procoder is good with interlaced content but I never used it that much.

looks like it could do with some filtering...

Thanks for that 45tripp. When you said "it could do with some filtering" - did you add filtering for your procoder3 encode, or is that the result without filtering? I looks softer to me, but I don't know whether that's because of a pre-filter, or is just the result of encoding it.

It still has noise, but it's of a different "character" to HC Enc - not sure which I prefer. It probably depends on the type of TV, and I haven't tried this on a CRT yet.

Cheers,
David.

no filtering.
wouldn't do that to you.
just saying.

it is,
it's procoder encoding.

i know what i prefer :0


actually i'd probably take lavc for interlaced encoding of mpeg2.
the easy way, using ffmpeg and a gui Avanti (http://avanti.arrozcru.com/)

might upload an encode in a bit

hmm, seems to have more noticeable blocking exactly where not wanted with the clip.
but sharpness/noise is nice

Try using VBR @8Mbps

I'm trying to max out the bitrate too for the highest quality ... any suggestions on improving this HC.ini which is used for PAL HD->SD ?
