Or the same function can simply be used to create a backup of these files. Until then, we will not be able to work efficiently with the direct footage from GH5 anamorphic.In addition, the application can also apply LUTs in order to make color correction adjustments. Developers need to reengineer playback engines of editors to use the GPU for faster playback. Use these settings in DaVinci Resolve StudioĬPU manufacturers need to develop faster processors need to become significantly faster. These codecs are easy for the CPU to decode- just be sure you are running them off of a fast enough hard drive or even better, a solid state drive. If PC, install and choose the Cineform codec. If you’re on a Mac, ProRes 442 will be your pick. No one likes proxies, but for now, the quickest and easiest solution is to convert your GH5 v2 anamorphic lens footage into a much less efficient (read: larger file size) but much less intense codec designed for editing. How GH5 HEVC looks in Premiere Pro The solution: You need to convert to an intermediate codec Even on a spec’d out top of the line system. On top of that, other odd bugs and issues between software and GPU make editing functionally impossible. So cutting through the technobabble: something as simple as loading a frame in the middle of the clip means a long series of intense calculations. This drastically compresses down the amount of data stored by the codec.įor playback, the CPU has to first decode the complete frame, store it that frame to RAM, and the call up the data for each of the next set pixel changes for each frame until the next complete frame. Interframe Long-GOP works by encoding one complete frame and then storing only the data for pixels in the image that have changed. Panasonic makes this even more difficult by using interframe Long-GOP compression to squeeze every bit of quality and efficiency out of the compression. At high resolutions, h265 is an intense calculation. While many effects can be offloaded to the GPU- opacity, scaling, curves, and more- the playback and render engines utilize the CPU instead. Unfortunately, most modern editors do not utilize the GPU for playback. The problem: GH5 Interframe Long-GOP encoding The basic Movies & TV app in Windows 10 with a Pascal GPU can play back all GH5 footage, even 8k h265 at full framerates, without even breaking a sweat. The player can do so smoothly while using a minimal amount of other system resources. This means that provided that the playback software supports it, a separate processor designed specifically to process only that task handles video decoding. This includes some of the latest NVidia (Pascal) GPUs, Intel processors, and even dedicated chips on mobile devices. Most new hardware includes native support for decoding (and sometimes encoding) h265. h265 allows for a maximum encoding of 8192 × 4320 at 120 frames per second. Moreover, the h264 codec is incapable of a greater resolution than 4096 x 2016. As the next generation of h264, h265 packs a lot of information- 50-60% better than h264 especially at higher resolutions. However, to compress this much resolution and color information, Panasonic had to utilize HEVC (h265). But, modern editing hardware and software are well capable of handling multiple h264 streams and applying effects in real time. h264 isn’t an ideal editing or capture codec like ProRes, DNxHD, or our preferred CineForm. The Panasonic records most footage in h264 wrapped in either. Shutter EncoderĪny of the current Adobe CC tools (Premiere Pro, Media Encoder, After Effects) will either crash or be extremely unstable at this time. You will need to convert your h265 footage to an intermediate editing-friendly codec such as ProRes (Mac) or CineForm (PC).įor PC, use Shutter Encoder or Handbrake to transcode your footage to Cineform RGB or ProRes 442.įor Mac, you can use Editready or Handbrake as well and transcode your footage to ProRes 442.ĭavinci Resolve Studio ($299) can also work, and will allow you to trim your media. The interframe Long-GOP encoding structure of GH5 h265 footage makes it mathematically difficult for even the fastest CPUs today to decide footage in real-time. Quick summary and solution to slow GH5 playback Note that the free version of DaVinci Resolve will NOT play back h265 or work with timeline resolutions greater than 4k anyway. Sluggish, slow, and choppy playback don’t even begin to describe it. But, even with a beefy i7 system and the latest Pascal NVidia GPUs will not come close to realtime playback. DaVinci Resolve Studio 12.5 and above will import the footage. The latest version of Premiere Pro CC 2017- if footage can even import at all- would crash or display colorful art in place of where footage actually should be. However, editing is going to be a bit of a challenge.
