Getting a solid 10fps during playback using Animation codec
I am using iShowU HD to record a screencast. I can import the videos into FCP with no errors and no rendering required.
iShowU settings:
- Apple ProRes 422
- Linear PCM
After editing, the videos must playback at a consistent 10fps in Animation codec. This is a requirement of the customer. When I export using either Compressor or FCP using QuickTime Conversion, the fps fluctuate between 0 and 10 during playback.
I have had success using the H.264 – Webcasting setting in Compressor. Unfortunately, the customer will not accept this format.
Is it possible to get a consistent fps during playback using the Animation codec?

Animation is a high-bandwidth RGB codec. What is the resolution of your screen capture?
If the video dimensions are large enough, it’s entirely possible that you won’t get consistent playback speed from a single drive due to the high data rate required to maintain smooth playback without dropped frames. If that’s the case, you may need to stripe several drives in RAID 0 to achieve the desired playback rate.

Full screen capture at 1024 x 768. I am still in the testing phase right now so the videos are around one minute in length.

Animation? Why not try ProRes 4×4?

That’s considerable. Drive speed and/or buffering to RAM speed are likely the bottleneck here.

Thank you both for the suggestions. I will give the ProRes 4×4 a shot and see what they say.

PNG is another pretty nifty codec in 8-bit, like Animation. I believe you’ll get the frame rate you want with it and it’s lossless at 100%. Also comes standard with Quicktime. Check out what is said here:

Thanks Dave.
I spoke to the customer yesterday and they have decided to accept H.264. They came up with an acceptable workflow to convert it to the Animation codec.

Thanks for the link. Good information to have!

Craig,
I’m in the same boat – do you know what they used to convert to solid 10fps animation?
Much appreciated

No, they did not say. I will ask them tomorrow and post back their response.
