<p>I'm trying to get started with Fusion. I have h.264 encoded video in a mp4 container. When creating a loader I get an unhelpful error of 'Loader1 failed at time 0'. Googling around I found some mention of not having the codec installed, so I pulled the CCCP and still had no dice. </p>

<p>ffmpeg also seems to be able to work with the files fine. I see some mention of Direct Show in the file format selector, but there is no option in ffmpeg to encode to that.</p>

<p>If I just try and mash a h.264 encoded stream into a container that appears to be supported, like avi, using:</p>

<pre><code>ffmpeg -c:v h264_cuvid -i preaudio.mp4 -c:a copy -c:v h264_nvenc preaudio.avi
</code></pre>

<p>I get errors that look like:</p>

<pre><code>Loader1 failed at time 0
Loader1 failed at time 0
Loader1 failed to load file "&lt;pwd&gt;\preaudio0000.avi" (clip "&lt;pwd&gt;\preaudio.avi" at frame 0)

End answer was dnxhd/mov. Use something like:
ffmpeg -i input.mp4 -c:v dnxhd -b 440M -c:a copy out.mov

The -b argument should be adjusted based on your input resolution. 440M is the correct choice for 1080p @ 59.94 fps.
