FPS irregularity with animation exports
I started with a series PNG files and in Quicktime created an image sequence (29.97 fps). Using QuickTime, I then exported a .mov file with the animation codec. I selected 29.97 as the frame rate. However when the resulting file is played in QuickTime the frame rate is reported as 27.09. VLC player also reports the frame rate as something other than 29.97. But when the exported file is imported into FCP it reads as 29.97 fps.
What program is telling me the correct frame rate of my exported file? How do you lock in the frame rate when exporting the image sequence to a file with a different codec?
Thanks

Hi,
This isue has been reported here just few days ago. Nothing clear.
When you export a still sequence with QT as a movie, you are not getting aTC track. In FC when you export you get a real one.
FC is a professional tool. QT is like a swiss-knife.

Thank you for the response. The odd thing is I exported out of Final Cut. I made an error in my report above. Just to clarify my workflow:
I made an image sequence in Quicktime with the Apple PNG codec. I imported that file into a FCP sequence and synched the video with an audio track. Then I exported the full sequence out of FCP with QuickTime Conversion. I set the options to use the Animation codec, 29.97 fps, etc.. The resulting file plays fine, but, as stated above, QuickTime player reports an odd FPS. Whereas when I use QuickTime Conversion and export an uncompressed 10-bit movie, the FPS is reported as intended–29.97.

I imported the animation .mov into FCP and looked at the clip properties. FCP says the clip has a frame rate of 29.97. I trust FCP, but am curious why applications like QuickTime Player and VLC report an unintended FPS when playing this animation .mov.

Thank you, sir.
One more thing of note:
In FCP I used the Analyze Clip option in the Tools menu. The animation movie had a frame rate of 29.97, but also had dropped frames (although it plays smoothly). The uncompressed 10-bit movie exported via QT Conversion also had a frame rate of 29.97, and no dropped frames.Not sure if that relates to my inquiry.

Hi Cutter,
Just a couple of things:[Cutter_Jones] “I made an image sequence in Quicktime with the Apple PNG code”
-This you better do it directly in FC. You can avoid do it in QT and then bring your movie to FC.[Cutter_Jones] ” Then I exported the full sequence out of FCP with QuickTime Conversion. “
– As long as you can, try to void export with QT conversion. You can not control nothing this way. You get not even TC in your movie. Export via QT.[Cutter_Jones] “I set the options to use the Animation codec”
Animation is useful if you need to export with an Alpha channel. If not you have better options like (if you want RGB) PhotoJPG 100%. Is loose less and make the files three folds smaller than Animation. You will have less problem of dropping frames while playing.If you go t finish in a DVD or so you better us 8/10b Unc.
