Motion adaptive filtering good enough?
i've notice that using the lastes script for AviSynth 2.52, when the camera doesn't move straight, but jumping, the background becomes blurry for a moment and then sharp for another moment, repeating this secuence...
It can be easily watched in secuences with people walking slowly... stopping at every step... ¿Has anybody notice that? |
You shouldn't be able to notice that effect when viewing normall and not in slow motion... can you post a sample please?

@ bicho_visaco..
>> Has anybody notice that? Yes. You are correct. I've ben noticing this too. I notice when the script does process, and comes to a "sceen change" the frame AT this change is distored, and following frames are clear. I don't quit think its a bug, but rather a script programing challenge. That is, if Kwag can incorporate -1 in this. Ok, I should elaborate on this ?? Yes, when the scene (hopfully true) is: * deteced, and * prepares to perform it's filter decision, it * should NOT do anything for this ONE frame. leave alone, and * then process the frames as such. if my logic is in error, please forgive me. I am a programmer, but I'm not familiar w/ this MDAS (Motion Detection Algorithm Script) But, it sounds do-able. @ jell.. are you jell'en w/ this ?? Later guys. -vhelp |
Anyone noticing this, make sure you have the variable scd_trigger set to at least 25, and maybe even 30.
The problem can be related to a glitch in the movie, and AviSynth's internal function "YDifferenceToNext()" can "false" thinking it's a fast change from frame to frame, when indeed it's a glitch in the picture. -kwag |
Hi there!
trigger was on 25 :? and I saw this effect on two scenes, one on the desert (movie Star Trek Nemesis) where those glitches could appear, but the other scene is onboard the ship and I cannot think about anything producing this... :?: By walking slowly I didn't want to mean seeing it slowly on the DVD, but the person walking carefully... ¿how could I post a part of the movie? It could make it easier to see the effect I think... :? |
@ bicho_...
it sound like you haven't IVTC'ed your source, and you are viewing those pesky Interlace lines. I hope I'm wrong, but then agian, I hope not. cause it would mean there is something wrong w/ the script. Can you tell us about how your processed your DVD RIP ?? Your process for: * dvd2avi * frameserver (vdub or AVIsynth, or directly into TMPG) * encoding settings under Video and Advance tabs Thanks. -vhelp |
I think the only problem could come from the source, a Xvid, but it could be dissappointing because most of us do recompress movies in this format to can watch them on our DVD's... :( The rest of the options are as always except the script, it was the first time i was trying the version 2.52 :? , and the script was no modified, it was kwag's script.
I will try to upload a portion of the movie for kwag to watch the effect but it couldn't be until tonight (European time). |
