View Full Version : Filters & Matrix for interlaced material with Procoder

I know this topic has been discussed many times, but I thought it wouldn't hurt to ask again to try and get some more "updated" opinions.

My source is a DVD of The Dog Whisperer, with interlaced 4:3 video, and has to be compressed almost 50% to an average bitrate of about 1900 kbps. I've tried the bach1 matrix using CCE and HC, and the results were promising (HC better than CCE on this interlaced material though). However I did still find DCT blocks during some motion scenes. So now I'm going to try Procoder which I'm told is excellent on interlaced source (at the sacrifice of speed).

What are some current recommended filters that I could use on such interlaced sources to remove the blockiness when using Procoder? Undot? Removegrain? What settings? Thanks for any input you guys can provide!

Interlaced material and an average bitrate of 1900kbps combined with fullscreen video means that it'll remain a blockfeast. To add to that, ProCoder doesn't support custom quant matrices, IIRC it uses the MPEG standard matrix.

aaah! That would explain why my procoder output wouldn't play on 2 of my 3 standalone players. I was starting to think it was DVD-RB that was the problem but it was probably the non-standard matrix that was screwing things up. Boulder do you have any filters you would recommend I use with Procoder to help with this encode?

No, ProCoder just won't use the matrix you set in DVD-RB - it doesn't affect standalone compatibility in any way.

I cannot recommend any specific filters, it all depends on the source. I'm just wondering how long the video is, 1900kbps is quite low. Or is there some LPCM audio track or huge menus eating all the space?
