Highly Recommending MSU Advanced Frame Rate Converter

Post by rook2pawn » Thu Aug 28, 2008 12:30 am

I am overjoyed at the ease and quality of the MSU Advanced Frame Rate Converter and I want to recommend it for all those who are interested.

It's free, and they have results that show their free product works better than Twixtor (i recall this may have been used in Auriga)


How easy is it to use?

AviSource("video.avi")
ConvertToYV12()
MSU_FRC(2, "slow")

Notice the integer 2 means to double. The positive INTEGER you provide is the multiplying factor.

Thus, if you have say a clip at 23.976 FPS, first Convert the FPS to 30FPS in either Avisynth(convertFps) or VirtualDub (convert to FPS) so that the right number of frames are duplicated. Then you can double it to get 60 or whatever yo like.

I imagine the technology and sophistication of these programmers must be pretty high, and that they decide to make it free for noncommercial use is impressive :lol:

eh, it doesn't look too bad on live action from the pics they provided, but interpolating the missing frames is gonna kill quality (not to mention making accurate syncing a lot harder)

more frames also means bigger filesize, and since quality is out the window you might as well use assumefps or covertfps in avisynth

Ive made about 20 different up framerates, (lotsa avisynth / vdub! one vdub to convert to 30fps, then an avisynth to x2 uprate, then a vdub to write it out at 60)

I have noticed that this looks best with fairly static scenes, not the "action perspective motion" shots that alot of AMV goes for. I *imagine* that Twixtor has same fundamental difficulties with those "high perspective motion" anime shots.

Im going to try post-post processing with BlindPP or MSU SmartDeblocker.

It does indeed work as advertised on that one Matrix (I did the test myself on those 2 frames just to make sure). However, as expected, it's definitely not a miracle plug-in by any means.

Here's an example of a 2-frame shot:

Pretty crappy. It seems like the plug-in only works well when there's VERY little motion in the scene. I did another test with 2 frames from a scene in Batman Begins where somebody is moving their hand with the thumb moving out. It interpolated the rest of the fingers really nicely, but where the thumb was moving away it looked extremely harsh.

So, yeah. It's a step in the right direction. But I'm not ready to put my trust in it just yet.

But to a certain extent, wouldn't the question be, is it really visible when viewed at regular speed? I mean, if we can hide a single frame for authorship purposes and that remains invisible, why would it be different with a frame that plays twice as fast?

In other words: once playing at regular speed, does the footage look fine or not?

Okay, the visual irregularities that look like Predator Camouflage are insurmountable.

I know the interpolated frame happens very fast, and my eyes did not catch it when i watched the finished result, I only saw irregularities on scene changes. But alas, I stuck my foot in my mouth :oops:

Is there a simple frame blending method anyone know of to create an interpolated frame?
