Estoy teniendo un problema en el export de video en ALPHA ProRes 4444 en PREMIERE PRO.
Este problema es reciente, empecé a tenerlo la semana pasada y no antes, mismo premiere, mismo equipos, mismos archivos, mismo proyecto.

Cuando exporto en 4k / ProRes 4444 / 16 + alpha / 30fps las letras pierden suavididad en los bordes. Estos son animaciones de texto y png, ninguno tiene efectos de ningun tipo agregados.
En el primer frame se ve bien y a partir de eso empieza a romperse la imagen.

Hice muchisimas pruebas con diferentes blendmodes. Hice pruebas abriendo una nueva secuencia. Hice pruebas cambiando la configuracion de color de la secuencia. Hice pruebas

DATO IMPORTANTE: Este error lo visualizo al reproducir el archivo en RESOLUME ARENA, VLC, QUICKTIME.
Cuando lo reproduzco desde Premiere, abriendo un proyecto nuevo y cargando el archivo como nueva secuencia, se reproduce correctamente con alpha sin errores en los bordes.

Alguién tuvo este error??? Dejo en adjunto imagenes de reproduccion en otros softwares.

Hello @Malen38190563z47s,

Welcome to the Premiere Pro forums! We’re happy you’ve reached out. I'm sorry your alphas are coming out with edge problems. Can you tell me which version of Premiere you're using? Would you be able to supply a sample clip for us to test with?

I'm having a problem exporting video in ALPHA ProRes 4444 in PREMIERE PRO.

This problem is recent; I started having it last week, not before. Same Premiere, same equipment, same files, same project.

When I export in 4K / ProRes 4444 / 16 + alpha / 30fps, the letters lose softness at the edges. These are text animations and PNGs; neither have any added effects.

The first frame looks fine, but after that, the image starts to break up.

I did a lot of testing with different blendmodes. I did testing by opening a new sequence. I did testing by changing the sequence's color settings. I did testing.

IMPORTANT NOTE: I see this error when playing the file in RESOLUME ARENA, VLC, or QUICKTIME.
When I play it from Premiere, opening a new project and loading the file as a new sequence, it plays correctly with alpha and no edge errors.

Has anyone experienced this error? I've attached screenshots of it playing in other software.
I also cleared the media cache and freed up some storage space.
But the problem persists in other players.

También borré el caché de medios. Y liberé espacio en la memoria de almacenamiento.
Pero el problema en otros reproductores persiste.
