Looking for 60fps FILM source
Does anyone have 60fps source which is in fact 24fps film and can be converted to it via:
SelectEven() Decimate(5) Please PM me if you need space to upload it to. Thanks. P.S. It's been a while since I was working on analysis of sources, may be its time to pick it up again

There is a file linked there. But see the thread to understand why it is problematic to convert as you describe. |

I have an 800MB 720p @ 60fps file of the space shuttle launch. But I don't know if it started it's life from film.
It would be nice if there were more 720p 60fps clips about. Cheers

Hi len0x,
I have not got the tools on this PC to cut segments from Mpeg2's. I've got the whole lot burned onto an 800MB CD~R so I can mail it to you, if you PM me with an address. I must admit I find these 720p 60fps streams rather intriguing. And would like to know how they start their life. Do they start as, 24fps film converted directly to 60fps 720p Mpeg2. Or do they start as, 24fps film converted to 30fps 1080i Mpeg2 to 60fps 720p Mpeg2? I suppose creating 30fps interlaced HD material into 60fps progressive could be done by turning each interlaced field into a full frame but why do this, unless it's to provide backward compatibility for viewers who don't have progressive receiving equipment? From what I have read, technically an 720p image should look better than 1080i image despite the fact each frame carries less pixels. But why use 60 frames and not 30frames to do it? Can one of you guys shed some light? Cheers

Hi you might try this, it works for me with the lotr1 1280x720 60p ts stream: LoadPlugin("E:\Program Files\AviSynth 2.5\plugins\MPEGDecoder.dll") LoadPlugin("E:\Program Files\AviSynth 2.5\plugins\decomb521\decomb521.dll") MPEGSource("Y:\!_Movies\absinth-tlotr.tfotra\absinthtlotr.tfotra.ts") decimate(mode=0,cycle=2) decimate(mode=0,cycle=5) you get a nice 23,97 f/s stream |

You can find it the newsgroups you might want to use www.newzbin.com in order to find hdtv streams currently posted on usenet Just search for "hdtv" If you become a registered member you can find more and download the .nzb files for the newsbin usenetagent I think currently tlotr can be found in a.b.hdtv Beware, not all streams wich are posted there are ts or even 60 P you have to be lucky |

@lord_malebolgia For pure FILM sources there is no need to do decimate(2) as it supposed to be equvalent to SelectEven(), only slower.

I used: selecteven() wich produces a 29,97 f/s stream but in this stream I find duplicates frames wich are the source for the jerkyness I used: selecteven() decimate(mode=0,cycle=5) wich produces a 23,97 f/s stream wich is still jerky, the cause of this is also duplicate frames. when i use decimate(mode=0,cycle=2) decimate(mode=0,cycle=5) wich produces a 23,97 f/s stream witout any duplicates frames so this stream has no jerkyness at all. the imortant thing is that i don't use normal decimate but mode=0 wich removes only duplicates. I used 2x decimate duplicates Because 1x would not remove all duplicates. This way works here because the original movie is 23,97 f/s and the ts-stream is a 59,97 f/s progressive stream wich wil reduced to its original framerate by just removing the duplicates.

I tried quite a few 'non-script' based applications to try and half the frame rate of the 720p clip, but to no avail. Trying to get 720p 'film' sources accurately back to film speed is going to be quite a feat. I'll keep an eye out for some more clip and post them to you if find them. Cheers

@ lenOx,
I converted the file that was mentioned by neuron2 above. Using DVD2AVIT3 it was downsized to 640x360 from 1280x720 (to be able to playback on Athlon 2200+working 1794MHz and on GeForce 2 400mmx) but keeping frame rate at 60frames/s.Audio is orignal AC3 5.1. VirtualDubMod was used to mux video and audio. Convertion was done in 1-pass mode by 3ivx with bitrate 200x8. No filters were used. I am interested what is your opinion about it. Sample mmmm.avi 1:22 (25MB) on: ftp://www.eb.enterpol.pl user: www.eb.enterpol.pl password : eb eb |

Afterwards I wil create a 23,976 sample from this stream. My intend is to post both samples in "alt.binaries.hdtv". the size of the post is about 50 mb. I wil "rar and par" those samples for saftey. The header will be "ATTN:lenOx" password for rar will be "lenOx" Is it possible for you to get it there ? Or do you have enough email space so i send it to you directly? I have chosen this sample because of the smooth movement it contains. With the avisynth script mentioned in my replies (59,976 -> 23,976) i get about 3 to 11 f/s with a P4 1.8Ghz the reason for using xvid is it can be played in native resolution on the XBOX media center wich can give the HDTV component video-out in 720p. 1280x720 is also the native resolution of the beamer I use for watching movies. I can tell you watching this on the beamer changed my view on DVD....its time for HD-DVD |

Selecteven() will DESTROY it and Decimate(5) with nuke it even worse. In fact DG has had to write a whole new decimate for these wacko patterns. go read this thread for more info http://forum.doom9.org/showthread.php?s=&threadid=77798 |

It would help a lot to have universal Decimate. My problem though is not to find out how to decimate properly, but just if I need to decimate at all in automatic way (i.e. without looking at the source manually). That's why I'm looking for sources with dupes for analysis.
