Quicktime export -- No more FPS info ?

[D.T. Nethery]

Has something changed about the way TVP exports to Quicktime ? (or am I only now noticing this ?)

In most applications I have (for example Digicel Flipbook) when I export to Quicktime the QT Movie Inspector panel will show the FPS info.

However, when I export from TVP the information in the Movie Inspector panel is abbreviated , and does not show the FPS , among other information that is omitted.

How can I have the more complete set of information show up in the Movie Inspector panel when I export from TVP ? My memory is that QT movies exported from TVP used to have
that information embedded in the Movie Inspector panel , so it was easy to check on the FPS and other information at a glance , but am I remembering it incorrectly ?

I just checked my QT movie files and see the same result: no FPS information since TVP 9.0.5. Other programs still include it, so it must be TVP. The files play correctly, though.

here, the H264 codec doesn't work (since V9.0),
but with all other available codecs, the quicktime exported files don't loose their FPS information,
(see exemple below, codec = video MPEG-4, tvpa pro 9.0.4, should I update ...?)

Au contraire - the file I checked was done with the PNG codec, and had ad lost the FPS info as well.

I now believe it's an Apple Quicktime problem (since the update to QT 7.5) .

I just tried exporting some movies from Digicel Flipbook and I get the same problem, no matter which compression codec I use. The FPS and timecode information is no longer showing up in the "Movie Inspector" panel.

Apple . Why , oh, why did they mess with Quicktime like that ? So irritating.


BUT wait ... now this is really maddening .... I just tried exporting a scene from the pencil test application called Toki Line Test . The scene exported with H.264 codec from Toki Line Test shows the FPS info in the
"Movie Inspector" panel . Now I'm even more confused. TVP and Digicel have no FPS info. in the exported movie , but Toki Line Test does show the FPS info in exported movies . How ?

Is this a known issue that TVP is aware of ? Is it totally an Apple problem (since update to QT 7.5) or is it something to do with how TVP is interacting with QT ? Same problem seems to be in Digicel Flipbook's exporting to QT,
but not in Toki Line Test ...

Again, it's not QT 7.5 related, since I still have QT 7.1.5 here ...

Oh, I missed that the first time (that you are using QT 7.1.5) .

So ,this is even more of a mystery to me . I just noticed this missing FPS and timecode info. recently , so I attributed it to the update to QT 7.5 .

So what's the answer then ? Anyone know what has changed ?

okay you guys and gals, i'm a total newbee here and haven't a clue what tvp is, but since i ran across this quicktime bug while using quicktime pro 6.5.2 today, i stumbled onto this site looking for a solution. maybe you've all worked this out already since i see this thread is like 2 years old, but i just figured it out for myself and so i want to share with you all because this movie-info-fps bug can really drive you crazy!

okay now, apparently the fps info depends on a calculation. you need enough frames in your movie to produce a duration of at least 2 seconds! haha isn't that stupid? for example, if my movie is 12 fps, then i'll need at least 24 frames to yield 2 seconds of duration for the movie info fps number to be shown. if i have say just 23 frames, then the fps info will not show because 23/12 = 1.91s duration and we need at least 2 seconds of duration for the info to show. this is probably the same issue for those of you using quicktime 7.

phew!! this headache is finally over! lol!

so have fun, keep smiling and fill your hearts with love.

"I guess it was a Vegas issue after all! Who'd have thought we were all wrong."

But it wasn't a Vegas issue, Apple broke QuickTime for everyone and in Apple's typical arrogance they expected everyone to "fix" their software to conform to the new QuickTime.

From the NLE Vegas forum thread on QT issues.

Since I'm programming with QT (for more or less 5 years) there never was a fps concept in QT.
Every frame has a duration, that's it.
fps are computed as an average only to show to people in info boxes.

Maybe there was something about fps in QT before that time, I don't know...

In my view, QT does it right... as a simple proof, what would all you animators think if we removed the instances from anim layers !
That's exactly how QT works.

[slowtiger]

Uhm, allow me to disagree. The concept of FPS clearly must be part of QT, otherwise no codec could give me options about the desired framerate when I export a video. I don't know how this is calculated internally, but I don't have to. All I must know is that I can put a certain number of frames insite a QT file, and that they are played back at the rate I want. Since I can choose nearly any odd number as FPS, and it always is played back with the speed I specified, this is the concept of FPS.

Of course it can be that what I call "25 fps" is called "each frame for 1/25 sec" inside QT, but the whole interface only uses FPS as a unit. As I said, I only care about the parts which I can touch and change, although often it helps to know the underlying concepts - in this case, to know that a minimum of 2 seconds worth of frames is needed to calculate the FPS rate and display it.
