Export at 18FPS

AAProds wrote on 5/28/2025, 10:49 AM

Did a search, no go. I know this was discussed some time ago but can't find it. I have a desire to export an MP4 at 18fps, which MMS 2025 won't do for any flavour of MPEG-4 (oddly, AV1 will "accept" 18 in the box but will export it as 25; bug report going in on that!).

VPX 12 won't do it either; does VPX 16 export 18fps MPEG-4?

I do have a workaround but it's clumsy and time-consuming.

Thanks for any replies.

My struggle is over! I built my (now) system 2 in 2011 when DV was king and MPEG 2 was just coming onto the scene and I needed a more powerful system to cope. Since then we've advanced to MP4 and to bigger and bigger resolutions. I was really suffering, not so much in editing (with proxies) but in encoding, which just took ages. A video, with Neat Video noise reduction applied, would encode at 12% of film speed. My new system 1 does the same job at 160% of film speed. Marvellous. I'm keeping my old system as a capture station for analogue video tapes and DV.

Hi Al

Is this the post you are referring to?

. . . . does VPX 16 export 18fps MPEG-4 . . . .

In theory you should be h.264/AVC and h.265 HEVC encoded video can be sub 10 fps. However in VPX and MMS the lowest framerate is fixed the the 'industry norm' of 23.98 or 24 fps is the lowest you can go.

Added: Looks like AviDemux is your go to for this one, so long as you do not specify Motion Compensation in the Resample FPS filter, crashes on my PC, None or Blend are fine.

Handbrake can convert to lower framerates however you are stuck with 5, 10,12, 15, 20 fps as the options 😨.
