video length not the same after exportation

[Kaarlito]

Hello,

I have a problem that I don't know how to resolve it since it is the first time it appears (Moho 13.5).

My animation is 2.40 minutes long (24f/s). But when I export it (4k), it is reduced to 2.24 minutes. I looked the options and everything looks fine. So I am a bit in the dark since it has to be a precise length.

Thank you for any suggestions or help in this matter!

If I were you I would export to an image sequence instead and do the rendering to video file with video software, like DaVinci Resolve. That way you keep the expertise of animation to Moho and the expertise of video to the video editor. And additional benefits are that when using PNG you have a high quality render in images that is future proof and the base to create several video formats from if needed (and most importantly has no compression like with fileformats like mp4) AND you can easily see how many and what frames are actually rendered.

It sounds as though there's a frame rate issue but it might be on the thing that you're using to load or view the video (i.e. your video editor / player).

to narrow it down:

- in project settings: how many frames does Moho think you have (start frame; end frame)? (and just confirm that the project settings does have 24 fps)
- in the exporter: did you export the whole range? (start frame; end frame)
- in the output file: check the file properties (in windows it's properties / details) to get the frame rate and duration that the file thinks it has
- in your editor: what is the default frame rate assumed for imported video (e.g. Premier: on the imported video, what is the frame rate in "interpret footage")

hope that helps

I looked all these options when I got this problem. I opened the video on Quicktime and FCPx, details infos: 2.24 minutes-24fps. On Moho, 2.48 min precisely should be 3456 frames (24/s) and it is. I export it (entire animation), I still get 2.24. It is a specially heavy file, for specifics reasons, the images are 300 dpi instead of 72 dpi, could be had something to do with?

dpi is not really relevant for anything other than scanners / printers -- if your image is (say) 3000 * 3000 pixels then it really doesn't matter if that will print at 10 inches square (300dpi) or (nearly) 42 inches square (72 dpi) -- its still a 3000*3000 px image.

3456 frames at 24 fps is 144 seconds (3456/24 = 144) that's 2 minutes 24 seconds (not 2.24 minutes; not 2.48 minutes) -- and if you look at the Moho timeline with SMPTE timecodes selected (Edit / Preferences / Timeline / Use SMPTE timecode) you'll see "00:02:24:00"
at frame 3456 on a 24 fps project. .... which leads me to think that there's something not quite right with the "2.48" number

can you check what the 2.48 actually means? (or did you mean 2.40 minutes -- which IS 2 min 24 sec)???
