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.
