24 fps with Videogreenspun.com : LUSENET : Editing DV Films : One Thread
Quick Question: I was wondering how to get an entire, lets say, 1 to 2 hour production shot on video at 30fps, to look like film at 24fps? We all know that filters take a while to render, so is there any other way?
30fps is too smooth and looks like TV, not film...

I have read that you can get a fairly similar effect that the filters give you (the movement blur etc, with out the film damage, and color temp). grnated it will still take quite a bit of time for an hour + peice.
you can take your elements or final video, depending on your editing system, and convert them to 24fps qt or avi files then convert them back to 30 for export to video tape.
or....i think ive read about people shooting in pal then converting to ntsc for a similar effect....or.....wait and invest in sonys 24 fps hd cam but that will be A LOT of money

If the 30fps you are talking about is all 60 fields, then yes it looks like video. On the other hand if every other field has been dropped, or the video was shot at 30fps progressive, then you really have just 30 frames and it should look much the same as 24fps.
If you have 60 field/30 frame video you can also keep only every third field -- this gives you 20fps. (Silent films were shot at 16-18fps.)
And you can shoot PAL (25fps). This gives you several interesting possibilities, like slowing the frame rate down to 24fps for editing, then adding 3/2 pulldown to take it to 30fps for NTSC video. This works, but you have to strip off the soundtrack before you do the 3/2 pulldown and then sync it back to the 30fps video.

In a back issue of DDC magazine, there's a great article on how to do a 3:2 pulldown on video, converting it to 24 frames per second. Then adding gain and adjusting the gamma, then putting a frame blend on, all done in adobe after effects. If you start with good video, then it looks pretty damn good. I've done scenes for actors' reels and nobody can tell it didn't originate on film. I haven't been that impressed with cinelook. They don't convert it to 24fps but put a time slur on and it still looks like video to me.

Sorry - not an anwser - Win, how can I get a copy of that article regarding film look in After Effects? I couldn't find it on the web.

i'm going to attempt to run thru the steps as outlined in dcc mag (dccmag.com) for use in adobe after effects
4 main characteristics of film 1.grain 2.3:2 pulldown 3. color tone 4. gamma correction
1. effect> stylize> noise filter (deselect- USE COLOR NOISE) a little grain goes a long way, experiment.
2. file> preferences> render settings template. click on new button and name setting FILM RATE. click on edit button and set quality to BEST, resolution to FULL, proxy use to NO PROXIES and effects to ALL ON. set frame bledning to ON for checked layers, and field render to LOWER FIELD FIRST or UPPER FIELD FIRST, depending on your video capture card. (experiment if you don't know, if it's not right, it'll be very jerky) Next, set 3:2 pulldown to WSSWW. To the right the USE THIS FRAME RATE should be checked and 30 should be in the window. if all is correct you should read frame rate sampling@24fps. click ok to exit and save settings as film rate. to make motion smoother, select ENABLE FRAME BLENDING in time layout window and select F box in footage layer. 3. effect> image control> color balance. correct color by eye, video usually has more green than film, so try taking out some. 4. effect> image control> gamma/pedestal/gain red, green, blue pedestal set to -0.4 red, green, blue gamma set to 1.6 now you're ready to render, make sure in render settings film rate is selected. these setting take a long time to process! GOOD LUCK, and experiment further to get the look you're going for.
if a scene has alot of motion you might have to add a small amount of gaussian blur.
