but when the nle does not incours in the 24 bit conversion --> image is ok

This problem occours only with windows 10. Windows 8.1 does not show images flipped and is ok.

Please anyone have idea how to solve?

Thanks

Easy. Stop using extremely outdated software.

Win10 doesn't use Directshow for preview/rendering, it uses MsFoundation classes. Your decade+ old editing app is having to go through a software api middleman/shim to get it to work at all. No surprise that you encounter issues.

Best practice: one should always keep their mission-critical workhorse apps in line with the OS(es) they were intended to support, and vice-versa. Use a VM if you have to.

Hmmm, the conversion to RGB24 apparently makes "something" believe the video frames are BMP images, which are read from bottom to top.

Yes, just leave SpeedRazor behind

IMPORTANT: "C:\" is not the right place for storing personal files! Definitely you are not a serious person

Not clear. Are you developer of the software? Is it programming question?
What kind of 24Bit conversion: conversion of what for what?

DirectDraw is important piece of backwards compatibility in windows and supposed to work forever.

marcorocchini is not a developer, he's a cat

The problem is, he expects that a jurassic software like his beloved Speed Razor will work flawlessly under every post-XP version of Windows...

The problem is not Speed Razor f.c. but Windows 10.
I have see the same problem also in virtualdub for example, I try to do any proof but for shure is a internal setting in the registry of windows 10

That's interesting, thanks for the new info.

Since shekh is the maintainer of the new VirtualDubMod, let's see what he says about the subject.

I don't use Windows 10 (specially a setup configured to "always update"), and I don't understand VirtualDub's source-code,
therefore,...

I cannot say much here. Yes image may flip due to program error, codec error, display driver error and hundred of other reasons.

You are using a video editor, yes?
Which has the capability to flip the video BACK, yes?
Then do so and move on!!

PS, it's the codec. I have had good luck with K-Lite Codec Pack; it is claimed to work with Windows 10, but I have not tested it.

PPS you have asked this question before, I see
