Render the movie
Once the you have selected the
device or set the advanced parameters, one click on the OK
button starts the process of rendering the video.
At any time during this process, one click on the "Cancel"
button stops the process.
Remark :
Depending on the device model or the advanced parameters which
you selected, the generation can take quite a long time.
Generally, for a Full-HD 1080p video :
- On a PC with 4 fast cores (Core i7 for example) : The
process will take approximately 2 minutes for each minute of
video to be rendered
- On a PC with 2 cores (Core 2 duo for example) : The
process will take approximately 5 minutes for each minute of
video to be rendered
This amounts to 2 to 5 hours for a one-hour video.
This duration will be much shorter for a video in VGA
resolution. That is why we recommend you to carry out all tests
and focusing trials at low resolution, and to render your videos
in Full-HD only for the last step.
