Hello there. Thanks for your replies.
When I tried rendering only 2 4K clips for a total of 30 seconds it took about 30 minutes to render but it did get it done. But when there are about 5-6 clips the software hangs. If it is true that PTE cannot handle 4K clips that is a total bummer. I think I should stick to a traditional video editor. I have the Sony Vegas. I just thought that PTE could do more with video clips and with ease. Anyone know if there is a return policy? Totally my fault for not demoing the product before buying.
denisb, I don't think it's my computer although I can't be sure. I have a AMD A10 7800 3.5 Ghz processor with 8 GB of RAM. But the graphics card is an integrated one.
