Thanks for the reply.
Due to the need to deliver the video yesterday, I entered the project in search of elements that perhaps I was not taking into account. I immediately noticed that the PNG images had an exaggerated size of 11mb, the resolution of the images was 1280*853 and it did not make sense for their size to be 11mb. In photoshop I was able to reduce the weight without losing quality and I continued to reduce the weight on a page dedicated to compressing PNG until I reached 30KB per image. I replaced the original files with the new PNG images and EUREKA the video was able to render at a wonderful 6mb without losing quality!!!
Every day we learn something new and I’m glad I was able to solve it and share it with you. Thank you very much again for the reply, I really appreciate it.
