Sorry but I’ve been struggling with the commands in the MP4 Normal profile to get handbrake to write the file with a constant frame rate instead of variable. I’ve tried using the -q command, but I guess I’m putting it in the wrong place. Can someone point me in the right direction on how to get it to create the MP4 files with a constant frame rate of 30fps? The profile I’m trying to edit is below.

[MP4 Normal]
Description=Main profile, good quality 1 pass MP4 (H.264/AAC) conversion. Good for most conversions, produces good results and is faster than the two pass conversion.

First, files are constant frame rate, I haven’t seen any “variable” frame rate files. The frame rate depends on the source file, you can however change it without having to mess with the profile, in the Conversion Task -> Expert Settings page you can enable the option to change the frame rate and set it to what you want.

Do you mean a constant bitrate? MP4 Normal is a constant bitrate profile. The -q parameter in handbrake indicates you want a variable bitrate.

Jeg ved godt, at dette er et gammelt indlæg, men denne tråd henviser til et problem, jeg har forsøgt at løse. Under Conversion Task->Advanced Settings (jeg kan ikke se et “Expert Settings”) kan jeg ikke finde en mulighed for at ændre frame raten. Er det en indstilling, der ikke er indlysende? Jeg kan se Maximum Width, Quality osv., men ingen “frame rate”. Jeg bruger version 2.3.13. Er denne indstilling i en nyere version? Tak.
