Hi,
I'm very happy to see that the initiative to make video recordings
of the PharoConf and MooseDay has resulted in so many
screencasts already published. Great work!
And now the first feedback:
- Format conversion: 62 of 72 GB done, processing the whole weekend.
- First 13 minute part currently encoding and uploading.
Still about an hour and a half to go.
- I would like to receive the presentation files to combine them
with video.
- Some of the material is difficult to use. Zoomed out too much
it is difficult to follow the speaker and the beamer screen is not
readable. Combining a screencast with the video only makes
sense when zoomed in (talking head size).
Why does this take so long?
- the video is in a format that I cannot work with directly, so needs transcoding.
I have been using VideoMonkey for this, which is based on ffmpeg. I have
the impression that this ffmpeg is not using the GPU, but only the i5.
I'm open for suggestions on better software for this in the future, as it takes the
whole weekend.
- I switched from iMovie to Final Cut Pro X. That allows non-linear editing,
so I don't have to wait for rendering to cut the movies. It remains responsive
even during the format conversion.
- video is much larger than the equivalent length of screencast. That creates
a upload bottleneck. 13 minutes of HD video is 733 MB. My home upload is
1Mbps (2 hours), so for uploading more material I'll ask someone at our
local university.
- I'm spending a limited amount of time during the weekend (and none next week).
