  1. Are you tasked with the content creation of a large-scale video wall? Are you tired of endless render setups? Is your After Effects machine in peril of a short flight through a nearby window? Why, oh god why isn't there a better way to split video files according to a pre-established grid of output cells. Now there is! I give you, the pre-split grid render script: https://github.com/florisporro/ffmpeg_presplitter What is it? A command-line tool that takes a large resolution video file canvas, and automatically splits it according to a grid of 'cells', where each individual cell is an output file with the correct cropping for that screen. You can enable or disable cells as your display wall shape requires. Features Enable or disable output files according to a grid Grid is automatically established based on input file resolution and requested output file resolution (defaults to 1280x720) Files are rendered to ProRes 422 Files are rendered to an output folder with the same name as the input file minus extension Much faster than Adobe Media Encoder Lightspeed compared to rendering directly from Adobe After Effects Works on any machine, doesn't need to have any Adobe software installed Existing files are skipped automatically Tested only on OS X, might work on Windows FREE as in sunlight (open source) Built for a recent project with @Hugo Janzen where we got majorly sick of After Effects render times. Requirements ffmpeg and ffprobe must be installed Node must be installed (available in Homebrew through 'brew install npm && brew install node') Have fun!
  2. Hi guys, Just wanted to quickly share some results from a few hours of testing. Observe this GPU load graph from our display computer: The first half of this graph is a video being played in H264, at 40mbps (encoded with ffmpeg, -fastdecode flag used), this does not play smoothly. The second half of this graph is a HAP video being played completely smoothly on the same system, at bitrate 1404mbps (a result of the peculiar resolutions and high framerate used). The video used for this test is a converted version of Big Buck Bunny, which can be downloaded natively in 60fps at resolution 4000x2250 here: http://bbb3d.renderfarming.net/download.html Does anyone know a good piece of software to log CPU load in a similar fashion?
  3. Thanks Erik! That makes HAP a very promising codec it seems. Am I correct to say that this is currently the only codec that has GPU acceleration in Watchout? I'm currently on a project where we're running into CPU capacity issues with MPEG2 at 2x Ultra HD resolution. I'll report back with my findings.
  4. Hi guys, Was wondering if anyone has experience using HAP as a codec within Watchout, particularly if hardware accelerated decoding is supported? I've noticed this on the Watchout 6 features page and the codec itself looks very promising. Although I see the limitations in hardware accelerated decoding, it could be very useful for some projects where primary considerations are a high / lossless bitrate and excellent performance. Experiences anyone? Floris
