@driftwood if the video is captured in 25 frames does it has anything to do with 1/50 shutter???

discussion is getting out of context. please retake proper topic

Like a lot of what we have to deal with, it's based on standards and engineering that has little to do with capabilities or limits in our current technology (like some dinosaur engineer thinking 16-235 in an already limited 8bit signal wasn't anything but retarded) but until everything changes you pick your battles.

@Jim_Simon

Audio isn't recorded as fps. The same 1 second of audio will sync perfectly to the same shot on video whether that video is recoded at 23.976, 24 exactly, 29.97 or 59.94.

This is a naive assumption. It sounds right but that is not actually how sound sync works. I'm also talking about audio recorded via an external source (the "throw away" audio I referred to originally is what's recorded on camera...it might maintain sync and might not).

Y'all should maybe google up some information on audio post for true 24FPS. You'll see that the audio has to be processed especially for that case. It's not drag-n-drop on your edit timeline. Yeah, if you're going to spend $20-30,000 to have a negative made of project shot digitally (or around $350/min for a short) they can walk you thru the process of conforming your audio.

If you're not doing that then you're just making a simple thing more complicated. If you just use on-camera audio then it likely doesn't matter but there's no guarantee. Audio and video are two completely separate entities, two distinct streams, contained in one file but neither dependent or married to the other.

Maintaining sync between two sources that weren't obtusely unrelated was one of the major hurdles that non-linear editing of digital source material had to overcome and it's only been in the last ten years or less that it's become as reliable as it is. One second of video is not simply equal to one second of audio.

edit: and I'm by no means asking @driftwood to remove this feature or grief him over it in any way since there is also the standard option of 23.976 in there. Folks who don't know any better are possibly in for some headaches if they aren't careful though. Basically, if you don't know for sure that you need to be shooting 24FPS you likely shouldn't be. Little videos where you're just laying in a piece of music and don't have dialog are exempt of course, do whatever, it's just a bad habit to be in if you ever need to shoot something that other people are going to work on, you're paid for, or where other people are depending on you to not waste their time.

Yeah I know that. It changed over 3 days from what I remember - do a search - I think you'll find my comment regarding it to VK - there was a problem in summit. Its always best to stay uptodate :-)

@Zaven13 Improvements in the code for 720p from what I remember. Long time ago. All Cluster X stuff has been developed on 3.66D nearly a year old now!!!

Right Nebula 6 GOP T7 is going up now.

@driftwood That Cluster X DrewNET T9 1080/24 screengrab looks great - quite a bit of detail from foreground to background. Great for documentary work I bet.

@jeffharriger Did somebody say "DVX100"?...damn, I'm not the only one who remembers that one! It was a pretty cool cam. Heard some guys hacked it back in the day, but even unhacked it produced a pretty decent image.

Cluster X Series 'Nebula T7' incorporating all the latest findings released shortly.

@driftwood: thanks, I'll try asap, just need time to "compile" ptool on Mac... Edit: no changes, still the same problem. I tried with a new clip...

T1000 - you may be putting the cart before the horse a little, don't start worrying too much unless you're thinking film out (who does that nowadays) or maybe DCP. Have you seen, say, THE MASTER on blu ray? Looks pretty good right? 23.976. * edit: Jim and Nick beat me to it and more informatively

@T1000

The film standard has been 24 fps exactly for a very long time now. Video trying to emulate film in the days of NTSC and CRT televisions came up with 23.976 because it worked with the scanning frequencies of the older CRT sets.

Newer flat panels don't have a lot of the limitations of older CRT sets, and indeed the developers of the ATSC and Blu-ray specifications were foresighted enough to include 24 exact in their specs.

Given the perceptible improvement in motion with 24 fps, I'd recommend using that for something you want to show in a theater.
