After effects rendering

 knew that the normal H.264 compresses the video and can alter the quality of it which made me think having footage rendered twice with the same codec may alter its final quality. I researched this online and the general consensus on this was that I should render everything in lossless until the final export from premiere the lossless format is uncompressed and does not alter the quality at all. A draw back is the lossless files are rather large but its worth it to not have our colour palettes ruined .
