Issues with AVI from M2V

That "inserting/removing frames" bit has always scared me from using Force Film.
I've usually chosen 'Ignore' instead because I don't want any frames removed. Do I?
Why would one want frames removed? Wouldn't it cause herky-jerky playback?
I just don't understand why or when, under what conditions Force Film might decide to remove some frames.
And when/why would frames be inserted? Where would the inserted frames come from? Repeats? Again sounds like a recipe for herky-jerky motion to my pea brain.
Is it even safe to use Force Film?

 

Using forced film is fine if your material reads as over 95% film in DGIndex, which it should do if you dealing with an NTSC movie.  Movies start life as 24fps, and this is, by and large, how they are stored on the DVD.  Pulldown flags instruct the player to turn this 24fps (actually 23.976) into the 30fps (actually 29.97) required by all but the most modern TVs for playback.  Removing the flags restores leaves the original 24fps in place and does not create jerky motion because when you re-encode after editing your encoder adds the pulldown flags back (assuming you choose the correct settings).

Sometimes material is stored on the DVD with the pulldown already in place.  If there is enough of this material on the DVD, then forced film might leave blended frames because it removed the pulldown incorrectly.  In this case you choose "Honor Pulldown Flags" and write an Avisynth to restore the original 24fps (inverse telecine) another way.

 The "Ignore Pulldown Flags" option is meant for power users as a testing mode.  It is a mistake to select it if you don't really know what you are doing. 

In short, use Forced Film unless you encounter a problem.  If you do encounter a problem, use "Honor Pulldown Flags" and inverse telecine in Avisynth.

Lol!  It won't come to that. :-)  If people act in that way, I put them on my ignore list and forget about them.  You don't lose the people with whom it's worth interacting, and I enjoy the internet more this way.

Lee, the other files for the SW '97 SE seem up and complete.  The upload seems to have gone perfectly. 

This was very enjoyable.  I thought the colors looked great.  There were some color fluctuations at various points, but this might have been in the source, and I didn't find them too distracting.  Other than that, great work!  I eagerly await the completion of the ESB upload. :-)

I was wondering as this is my first upload to a news group if someone could download this and report back if its a good upload or not before I proceed to upload anything else. :)

I've already downloaded most of it.  I'll let you know at the end of the download if there are any problems. :-)

So NO ONE here knows how to encode a lossless avi using x264 LOL?

You write an Avisynth script pointing to the AVI:

Avisource("whatever.avi")

and feed that to a GUI.  I would recommend something like ASX or XviD4PSP to start off.  They are both fairly straight forward and have features for resizing and cropping.  Personally, I perform my own calculations for resizing and cropping and add them to the Avisynth script.

No one can objectively tell you how much difference you will see.  I imagine that you will see very little difference between those two bitrates, assuming that all other settings are the same.
