Deletframe, Duplicateframe, Freezeframe limit?

[hartford]

Reguarding Avisynth 1.5.5:

It seems that there is a limit on the "frame" function, somewhere
about 1000 frames (1024?).

After entering about 1000 "arguments" in Avisynth I find that further
arguments are off by one.

If I do this:

deletframe(10)
dupilicateframe(10)
Freezeframe(x,y,z)

|
|- 1000 args here
|
Duplicateframe(xxx)
Deletframe(xxx+2)


then insert _ANYWHERE_ in the list one more argument, then _entire_ list
is off by one.


I'm guessing that the limit is 1024.

It doesn't make sense that there should be any such limit.

There is, however, a limit to number of filters you can have in your chain, because eventually you'll overflow your stack.

If you have a lot of DeleteFrame/DuplicateFrame/FreezeFrame calls, you might want to give my RemapFrames (http://www.avisynth.org/stickboy/) plug-in a try.

I can safely say freezeframe, duplicateframe, deleteframe can handle at least 1000 instances in my personal experience, I think one of my friend script it within a function to fix frames and called it around 5000 times and it was still ok, I never got to see the script to verify the cout though ^^;

I used no filters.

I had filtered this clip using restore24. That produced some "jumpiness" and bad blending that I wanted to remove. I got to about
25% of the clip using the frame args when I noticed the "off by one"
problem.

Well, guess that I'll just use VDub markin-markout along with specific
frame statements.

Thanks.

Thanks. I'll take a look. I'll let you know how it works for me.
