Cli Support for Donald Graft's Dgpulldown
 

DGPD 1.2 by Prodater64

Donald Graft has not yet provided CLI support for DGPulldown and as 25 to 29.97 pulldown is very interesting and it would solve many problems with sync issues, I wrote a little app that gives CLI (or parsing parameter) support to DGPulldown. It means if you parse 25fps video stream name as parameter, DGPulldown will do its job and you will obtain a 29.97 flagged video stream. You can use it with original audio without change it.
You need DGPulldown.exe and DGPD.exe the litte app I wrote. A DGPD.bat file included is only an example of how to call DGPD.exe.
All files should be in same folder.

Parameters are, first, path to m2v or mpv file (I think DGPulldown also support programs streams, but not sure), second source and target fps as 23.976/29.97, 24|29.97 and 25:29.970. 23.976/29.97 performs usual pulldown, so you can replace usual pulldown.exe for DGPulldown. 25/29.97 performs new way to do pal to ntsc convertion without any async issue.

You can use custom values, but in should be allowed values. Program don't take care of this, so be carefull.
You can use any of "/", "|", "-" or ":" separators.

Examples: Call it from a batch file

start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "25/29.97"
start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "25|29.97"
start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "25:29.97"
start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "25-29.97"

start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "23.976/29.97"
start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "23.976|29.97"
start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "23.976:29.97"
start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "23.976-29.97"

I think you can call it from any script or programing language that can send parameters to the exe file.

Tested in Windows XP. (it would work in any w32 system).

This sounds like a very useful addon to DGPulldown, great work Luis and thanks. :)

Updated.
v 1.1

Thanks for the update Luis. :)

Your welcome.

Updated v. 1.2
Now supports all legal fps.

This looks like a very useful tool that I am eager to start using!

For a complete newbie when it comes to scripting or programming - how would you recommend I go about running this in Windows XP?

Thanks!

Already answered :
Honnestly, if you don't understand the line in bold, the tool is useless for you.

Do use DGPD.bat file, edit it and change its values for your owns in the command line:

start "DGPulldown CLI by Prodater64" /wait DGPD.exe "path_to_\film.m2v" "25/29.97"

Thanks.

I wasn't certain that the "batch" file Prodater spoke of referred to a standard .bat file that could be run from Windows.

:oops:

Although, I agree that it would have been easy for me to try it out first before asking the question - at least now noone else need ask the question again.

Dont worry.
Your welcome.

Note: If you keep the name of cmd window "DGPulldown CLI by Prodater64" DGPulldown will run nicely just in front of cmd window.
If you change the caption, cmd window will popup as you have it configured in your system. Just try it to compare.

Thanks again Pro for the new update and the added feature. :)

:wink:

Luis:

I finally got around to converting the PAL DVD I had to NTSC, and your program worked like a charm, thanks!

Quick question though... it seems that DGPulldown already has a function built in to do 25 fps to 29.97 fps pulldown, so not to seem ungrateful, but what exactly does your program do differently?

Thanks!

I did say it in my first post:

DGPulldown was firstly made with that purpose, it is to say to permit 25 to 29.97 fps conversions of progresive sources without change the real fps of the stream. It really stay in 25 fps. Once applied DGPulldown, it adds flags, fields, not frames, then your stream will be perfect synced with your audio, and do need lesser btr that real conversion.
Another conversions are just same than usual pulldown.exe.
I only gift command line support to DGPulldown. If you dont need batch processing, you can do original Donald Graft's DGPuldown GUI.

Thank you for your feedback.
Enjoy the program.
