MPEG-4 Export Advanced Setting Problem with Frame-Rate

onium wrote on 6/11/2012, 1:32 PM

Hello,

I have noticed that when I try to export a 720p 60fps movie to MPEG-4 and I click on the Advanced Tab (see image below), the input and output frame-rate say 25fps. I can change the frame-rate by typing in the correct but when I click 'Apply' it reverts back to 25fps. Anybody know what is going on? Is this a bug? I want my MPEG-4 export to preserve the frame-rate of my source video, why does the number appear different in the Advanced Setting tab?

Please see image below:

I am using MEP MX Plus on Win 7 64bit (not using CUDA for render).

Thank you, jeremy

No it is not a bug this like your post re audio depends on which preset option you select. 59.97/60fps is available, as shown in the image, for some but not all preset options.

Standardisation only allows certain combinations of video/audio codecs, bitrates and frame rate.

Thanks John,

I understand about that dialogue and its preset choices, however I am referring to the window that opens when you click ADVANCED and then do it again where you are presented with the Main Concept Codec Setttings. I did notice that even though the settings in that dialogue say 25fps that the output MPEG-4 is still at 59.94fps setting in the prior dialogue that you referenced. Do you know where to find more explanation about the settings for the Main Concept Codec? I couldn't find anything on thier website. See the image below to understand what I am referring to.

Hi Jeremy

I don't know whether it is because this section is disabled or not but I have never been able to see any changes in the output after altering any of the "advanced > advanced" encoder settings. I have been able to make that frame rate change stick but can not remember how. As you have found the file still comes out at 60fps or whatever you have selected as a preset in the main export window despite what it reports there.

Puzzled as you are.

What would be really useful here is the "from file" button that is present in the MPEG2 advanced settings that lets you navigate to the camera original file (or some other MPEG2 encoded file for that matter) and applies the same settings for export as the camera used to create the clip.
