After changing my Linux and reinstall Kdenlive I can't edit the Render presets.
If I can't create my own render profile and use kdenlive render profiles my rendered final video will have very huge size and render time will be very very long !

I can only give some settings graphically like this image :


NOW i need to create a preset by this options but i can not edit text commands of preset :

Code: Select all

f=mp4 vcodec=libx264  crf=24

When I try to edit it as text in other tab , it shows this error :

Code: Select all

The following parameters will not have an effect, because they get overwritten by the equivalent user interface options: f

This problem did not exist in the previous version of Kdenlive and i can edit preset by it's commands :

We can no longer edit the Render profile (preset) by edit text style (ffmpeg commands ) and kdenlive is no longer useful (
we can't change simple crf value for a render profile

With version 22.04.3 it should work without problems. Even before that, everything could be set:
Edit preset > Video > Codec: libx264; Bitrate: 0k; Buffer Size: 0 KiB; Quality > 21 (=crf) or what you want.

I tested in version 22.11.70 and a button has been added under profile preset ( In other tab ) : Enable Manual Mode
and a warning message like this :

Code: Select all

Enabling manual editing is for advanced users, you will only be able to edit the settings for this preset in a text box.

when i click this button i can edit preset in command mode ! this option added in this version

You can make such beautiful screenshots. (How do you make it so you can post them here? Unfortunately, I do not succeed.)
Can you show me where this button is?
I have "edit preset".
And my Kdenlive version is 22.04.3
