EditStock footage is optimized so that editing can begin immediately, with no rendering or transcoding. However, older NLE's probably will not be able to support the H264 codec. If you need a purchased product in a different codec than what is offered, contact us. In some cases we will be able to accommodate.
Our goal is to keep the quality of our footage as high as possible, while keeping downloads and uploads moving quickly. Even though we usually get all our footage in its highest resolution, we have compressed it into an NLE friendly version. Our goal is to download, upload, and edit quickly, not to screen theatrically in 4k.
