Default Does Ver. 5 downconvert to SD interlaced better?

Ive had problems with HD footage (720p, 24f) in Edius when I change the project settings to 480i so I can export/print/record the project to NTSC video tape or DVD. The problem I exerience is alot of stair stepping, jiggly lines, anti ailiasing when there are busy patterns or thin lines in the video footage. I understand this is a progressive to interlaced conversion problem. Problem also was there when exporting/converting via Procoder Express. Has this been improved upon at all with Version 5?

Anyone compared? Or do we still need the Virtual Dub method?

Don't know yet my copy should be here this week and will be the first test off the rank.
I keep some really problematic clips just to test this and have given then to people using other programs but no one will confirm either way, interesting

Edius5 is the same as 4 in that regard, hopefully someone is working on something?

Virtual Dub (free) with 2 simple filters (resize and sharpen by 8) does an unreal job and the conversion is realtime on my PC, meaning a 1 hour HD HQ clip will take 1 hour to convert to HQ SD, then I can encode to SD DVD with no artifacts

Sorry, but I agree with Anton. I haven't seen any big moves on this subject compared to 4.61

Which version of Virtual Dub - the original or one of the mods? Or will any work OK?

Default Widescreen or 3x4?

Anton - when you do the Virtual Dub (which I too love!) conversion from HD to SD - do you usually end up with a 16x9 widescreen letterboxed SD version, or do you crop for a 3x4 SD picture? I've run into more artifacts when I crop it than if I keep the native 16x9 ratio. Even with a slight sharpening and sometimes a small amount of motion-blur. Same with you?
Cheers,
Alan

Hi anton,

Have you tried going from HQ AVI (HD) to SD (MPEG2) in TMPEGEnc X4?
