Convert 720x480 to 640x480

[SameSelf]

Encore is for authoring BD and DVD.

I looked at two screen shots and honestly couldn't tell the difference.

Try with this video.

Is that some telecined video with a 2:3 cadence? I have no experience with that sort of video. All my video is video I shot myself. And I never use 24p even though I could. I supposed I could generate some line grid in AE to test it out. But since I had to drop down to 1280x720 and can't think of an alternative method of resizing, there is not much point anymore. Although it would be interesting to see if there is a difference.

You can't feed 1080p60 on a video BD or video DVD.

You must convert it first and Encore is not the tool you would want to use.

Try resizing to 720x540 or 640x480 before upscaling to 1440x1080 or 1280x720. You'll find severe artifacts. The patterns are chosen specifically to show that it can't be done cleanly but you will find similar patterns in a lot of real world video. Blinds in a window, the pattern on the size of a skyscraper in the distance, etc.

Spline36Resize(720,540)
nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1440, fheight=1080)

But you can resize directly to 1440x1080 without severe artifacts.

nnedi3_rpow2(2, cshift="Spline36Resize", fwidth=1440, fheight=1080)

Be sure to view the images at their original size.

Not true. Do you have Encore? Try it. That is what the fake interlace flag is for. Doesn't even trigger the Transcode flag. I just finished authoring a blu-ray in 1920x1080p60. I just found that Encore is sluggish and since I am scaling up SD video, the cost outweigh the "benefits".

Jagabo, thanks for the post. I can see what you mean by artifacts in the top left quadrant of the top image. I am surprised that resizing to square pixels then doubling introduces artifacts while doubling then resizing to square pixels does not. But, that is why I keep coming back to this forum. So much to learn about video.

"Fake interlace" means you have a 1080i (or 576i/480i) stream on BD which contains so called "progressive segmented frames" (PsF). However, since the frame rate is of course 25/29.97 interlaced you still cannot put 50p/60p on BD, except for 720p. PsF means you have a progressive video of 25 or 29.97 fps and encode it as if it were interlaced.

I have read about flagging 1080p29.976/1080p30 video as interlaced for Blu-Ray, where each frame is delivered as 2 simultaneous fields. Although the number of fields per second that created was within the spec, some old players supposedly had trouble with it.

Flagged as interlaced, 1080p59.94/1080p60 would create twice as many fields as the spec permits, and is likely not to play correctly on some players.

LOL, funny watching people fall over each other to be the first to point out something wrong.

LOL It's a joke. It's more about being unintentionally repetitive. No current members here that I am aware of actually care who is first.

It is true that some would care if someone claims to have done something that no Blu-Ray authoring program should accept.

U should see what I do on BD. It would blow ur minds!

I doubt it. Someone can do anything they want with media files burned as data on BD.

You mentioned using Encore. As Blu-Ray authoring software, Encore should follow the spec and either reject or convert 1080p60 video even it it is flagged as interlaced.
