OS: Windows 11
Kdenlive Version 25.12.1
(Español, mi idioma original, abajo).
I’m going crazy because YouTube Shorts is causing my videos to lose quality. I export them in full HD from Kdenlive and they look perfect. I’ve had two different experiences:
The first is transcoding the video because importing the MP4 gives me an error. I run it through lossless Matroska, and it creates an excessively large file of over 200GB, which I can’t afford to have online.
The second method is ignoring the bitrate warning (it’s not constant) and exporting anyway with the Lossless/HQ H.264 group. This way, it doesn’t work. When I upload it as a Shorts video, the quality drops and it looks distorted—a bad image.
I tried cloning the H.264 and creating a new preset with a constant bitrate (CBR) of 25kbps, since, according to my information, if you’re exporting full HD, the ideal bitrate is between 15kbps and 25kbps.
However, when I try to export it this way, the render crashes and I get this log:
Started render process: /kdenlive/bin/melt.exe -loglevel error -progress2 %2Fkdenlive-DdwlpZ-1.mlt
[comfortnoise @ 000001fa80d39c40] Specified channel layout 'stereo' is not supported by the comfortnoise encoder [comfortnoise @ 000001fa80d39c40] Supported channel layouts: [comfortnoise @ 000001fa80d39c40] mono
[mp4 @ 000001faffcc3c00] Could not find tag for codec a64_multi in stream #0, codec not currently supported in container [consumer avformat] Could not write header 'FILENAME.mp4'
Rendering of FILENAME.mp4 aborted, resulting video will probably be corrupted.
I don’t know what to do. Just to clarify: I export a full HD video in Kdenlive and then convert it to Short format in Adobe Rush, since Kdenlive seems too clunky for quick editing and Rush is much more user-friendly. I don’t have YouTube Premium, so please refrain from telling me to pay for it. Thanks.

Me estoy volviendo loca porque YouTube Shorts me hace perder calidad de mis vídeos. Los exporto a fullHD desde kdenlive y se ven perfectamente. Tengo dos experiencas distintas:
La primera, transcodeando el vídeo ya que al importar el mp4 me da error. Le paso lossless matroska y me convierte un excesivamente gigantesco archivo de más de 200GB que no puedo permitir estar ahí.
La segunda forma, pasando de la alerta del bitrate que no es constante y exportando de todos modos con el grupo Lossless/HQ H.264. De este modo me sale mal. Al subirlo como Short la calidad baja y se ve distorsionado, mala imagen.
Probé a clonar el H.264 y generé un nuevo preset haciendo que el bitrate sea constante (CBR) a 25k ya que, según la información que tengo, si exportas fullHD lo ideal es que sea entre 15 y 25.
Sin embargo, al intentar exportarlo de esta forma, el render crashea y me saca este log:
Started render process: /kdenlive/bin/melt.exe -loglevel error -progress2 %2Fkdenlive-DdwlpZ-1.mlt
[comfortnoise @ 000001fa80d39c40] Specified channel layout 'stereo' is not supported by the comfortnoise encoder [comfortnoise @ 000001fa80d39c40] Supported channel layouts: [comfortnoise @ 000001fa80d39c40] mono
[mp4 @ 000001faffcc3c00] Could not find tag for codec a64_multi in stream #0, codec not currently supported in container [consumer avformat] Could not write header 'NOMBRE-DEL-ARCHIVO.mp4'
Rendering of NOMBRE-DEL-ARCHIVO.mp4 aborted, resulting video will probably be corrupted.
No sé qué hacer. Por si está la duda, sigo aclarando cosas: Exporto un vídeo en fullHD en kdenlive para después convertirlo a formato Short en Adobe Rush, ya que kdenlive me parece bastante tosco para poder editar rápidamente y Rush es muy cómodo. No tengo Premium YouTube, podéis evitar decirme que lo pague. Gracias.
