I have done a comparison between 1080p exported from a PAL sequence in After Effects (AE does the rescaling) versus a full 1080p export subsequently downsized in Virtual Dub using Lanczos rescaling algorithm - and the second way is much better indeed. Much sharper.

@Nik Skjoth
For small project you might be able to do so. But it's not ideal to do it for a big project with thousands of clips. You'll be spending all your production time scaling those clips one by one in the timeline. @Mike Hannon What plugins do you use for Virtualdub to be able to read your 5Dmk2 files? |

Hi Desmond,
I convert with Neoscene first, so I'm importing an AVI. |

Or you can throw the whole HD sequence into the SD sequence and scale it to frame size. Just like working in After effects with precomposed sub sequences... Easy as pie. |

Nik that's just a neat trick. I didn't see/notice that feature before. I know we can do this in after effects.

I managed to download it all and install the quicktime plugin but it keeps saying "unable to locate video codec to decompress video track" Any ideas? Cheers

TMPGEnc has a batch processor that's implemented in a common sense way (click on the "register batch process" instead of "start encode").

@ Rick Hill.
Virtualdub as of now doesn't understand Canon 5Dmk2 files. It doesn't have a codec to read in those 5D files. Hopefully they'll have an update for this soon. |

So I exported an image sequence and resized each frame in Photoshop to SD image size. It was 10 minutes of footage and the export and resizing took about 4 hours on my 2.33Ghz 4G RAM Macbook Pro. Sounds like a lot of time, but really not with my specs. The import and saving of the new image sequence took maybe another 40mins. Thing is then I would have to re-render it again with sound put back in.
Anyways, the outcome was much better then any other option I've tried. I didn't get the moire and aliasing in the footage I was getting by just having adobe media encoder render my project out for DVD. I compared the DVD to an actual Hollywood DVD played back in the same player on the same HD monitor and the jaggizes on diagonals were about the same. I think our perception is so critical because we see this great HD footage and used to believe the DVD was such a "perfect" format 6-7 years ago that we can't accept all the flaws we now see that probably were always there but we accepted it. Until HD came around. I don't understand why AME isn't just taking each frame and resizing it like Photoshop does? Yes this would be time consuming, but shouldn't we have this option at least? |

I have found that the problem isn't that noticeable going straight to dvd. Basically I have found the following: Canon 5D mov -> Matrox 1440x1080 AVI -> Edit -> SD Mpeg DVD = acceptable Canon 5D mov -> SD AVI -> Edit (looks bad already) -> SD Mpeg DVD = still looks bad
