Hi,
Is there a way to remove the pulldown flags from a progressive NTSC m2v/mpv file?
It is so easy to insert them using dgpulldown but I can't find a program to remove them. I want to edit the m2v stream so I have to remove the pulldown. Creating a d2v file using dgindex doesn't work for me.

You can do it with DGPulldown. Use the custom frame rate and set both the starting and ending rates to the rate of your stream. Don't you read users manuals? :)
From the DGPulldown manual:
"Note that if the custom rate conversion is selected, and if the source rate is
specified as equal to the destination rate, then all pulldown is removed and the
stream is flagged as having a rate equal to the specified destination rate."

I don't know if that will work (since you are the creator of dgpulldown I guess you know :)). Doesn't it turn a progressive stream into an interlaced stream?
I only read the text file that came with dgpulldown, and it only explains the option you can select in the program. I didn't know there was a manual. Sorry.
But I just fill in 23.976 2 times?

Hi Donald,
I've been meaning to ask you for some time. When the pulldown flags are removed from "known" progressive stream.

Would it be possible for you to add an option to correct the streams "Sequence Extension" flag to "Progressive"?
Many thanks

I only read the text file that came with dgpulldown, and it only explains the option you can select in the program. I didn't know there was a manual. Sorry. The text file *is* the manual. It's right in there. Maybe you have an earlier version. Check the latest one.
But I just fill in 23.976 2 times? Exactly. Try it, you'll like it. :)

I thought that because of the "top field first" option.
Thanks for the help :)

Ah, I see. But think about it. When you play video to an interlaced display, even if it is progressive video, the display process has to play one field at a time, and it wants to know which to play first. If the video is progressive, it doesn't matter which comes first; if it is interlaced video, it's very important to get it right.
