well I did some tinkering and managed to render the premier project via media encoder. Doesn’t work with audio via export in premier or ‘make movie’ in after effects with audio.

I noticed that it takes an additional 5-10 minutes rendering audio files at the start in media encoder but it was giving me visual feedback confirming it was actually doing something, so I waited and it eventually actually rendered the video with audio. So maybe if I left it in ae or premier it would start rendering eventually but this works fine I guess :/

I sound like a noob maybe but its never happened before.

The possible cause is the codec the D7000 shoots in is avc. AVC files are not meant for video editing. Its not the speed of the computer, the editing software can’t deal with them because of the way AVC encodes the video… even thogh they are technically supported.

The solution as far as I’ve found is to create proxies for what you want to edit, edit those then replace the footage via the ‘replace footage’ option in the media manager and render the timeline from there.

I am no expert but I’ve gone through this as I’ve recently shot a lot on the sony nxcam which also shoots in this format. Most new HD video cameras do. If the cam came with a video management software it will probably play them back fine but of coarse you can’t edit them. Apparently certain editing software have fixes for this but you also need a compatible and higher end graphics card to edit the original files.
