Hey guys, I really need your help. I have a sequence with mixed footage, 4k so 25fps, and HD 100fps. The fps of the sequence is also 100fps. I have done this multiple times with other video’s but for some reason, my video now has these blacklines when I render it, they come and go throughout the video. I have tried exporting it three times already, I have set the sequence to 25 fps instead of 100fps, I have tried to change the frame rates of the raw clips with this tutorial: https://youtu.be/_j8-jzOey8?si=Cyd7ChX6O3IhaEH. But it all did not work. Does someone know what to do?

Thank you for the screenshots @Spotlight34498917nnnl. If you click 'More...' under Basic Video Settings in the Export window, are you able to choose Software Encoding instead of Hardware under the Encoding Settings section and try that?

First of all, thank you for taking the time to respond to me today. These are only appearing on my final exported version, not during editting. My drivers are up to date and this only just happend with te mix of 25 fps and 100fps, an hour ago I rendered something with only 100fps footage and that one came out fine! So I assume my drivers are up to date. I have my settings and codec attached. Thankyou In advance! I use premiere pro 2024.

Hi @Spotlight34498917nnnl,

Welcome to the Premiere Pro forums and sorry for the frustration. We need a few more details to try to help with the issue, like hardware specs and Premiere Pro version you are on. Please see, How do I write a bug report?

Are these lines appearing on your actual export only or are you seeing them in the Program and Source Monitors as well? What type of media files are you working with and are your drivers up-to-date?

Hope we can help you soon,

Dani
