![]() Talk about willing to give info but NOT want to be quotable! Yeesh. confirmed by one of the Panny people at NAB. Apparently, the GH5 uses the same compression settings for both 8 and 10-bit 4k. ![]() up to now, it hasn't been necessary to get off to the lesser-used settings for more "extreme" compression. One of the "breakthroughs" for the GH5 was changing the compression settings for a more extreme level of compression, in order to manage 4k 10-bit for internal SD card recording. With the compression settings they used for that camera. The GH4 couldn't record data fast enough, small enough, to "pipeline" through to an internal SD card. And the DSLR's that have shot 4k haven't been trying to also do it in 10-bit, which requires a ton more data be recorded than 8-bit. none of which is in an interframe codec like H.264 or mp4. They work in log, CinemaDNG, or ProRes typically. Many of the cameras that have been doing 4k are the big 'professional' rigs, REDs & such. Others are "there" but just haven't ever been used so NLE's might tend to ignore the possibility. Some are perhaps, possible but not recommended?. There are many choices for various settings for the use of H.264 and other long-GOP compression schemes. You might also check in on the Hardware forum. there's far less for the computer to do to play that media back. even though they're 2-3 times the file-size per clip. For best playback the full intraframe codecs like Cineform YUV 10-bit, DNxHD/R, and ProRes edit far smoother with more effects. they are actually not even close to the same. don't confuse small file size with good playback. ![]() 4k 10-bit with the long settings between I-frames that are used by drones & DSLR's is incredibly taxing on the CPU for cores/threads/RAM and other subsytems. Long-GOP media is a pain for the CPU in 1080p. but never say exactly when "soon" will be.Įven when they get it fixed, I would strongly recommend ingesting that media with a proxy for most of your editing. They've acknowledged the problem and said they're trying to get something out quickly for this and a few other problems. The PrPro team thought they had this fixed in the last partial update, but lo. And most of the NLE's out there are struggling to handle it with the settings that come from the camera. which is a vastly larger data set to record than say 4k 8-bit or 1080 8-bit. There are some "interesting choices" that were made by Panasonic in getting a fast compression of data to card when recording the 4k 10-bit. Others on this board and elsewhere claim that they can edit GH5 4k footage on similarly configured but not identical Macs.Īny thoughts on what is happening here? Am I just using too small a video card for this? Obviously 32GBs RAM seems to be enough, according to Activity Monitor. I can transcode everything to 2k, or fix this problem. Video footage on RAID 1 Thunderbolt mirrored drive (7200 rpm). I shot some small clips on a GH4 a year ago and they worked fine on this system then, using an earlier version of Pr.ģ2 GB RAM (Activity Monitor showing that when the 4k footage is loaded into the project prior to crashing, only 16GBs of RAM is being used.)Ģ GB Video RAM GTX680mx (could this be the problem? )ġ0.11.6 (el capitan) (is the newest OS upgrade better able to process the video in Pr)? This is the first 4k footage in over a year. I can edit 1080p footage that was shot of the same concert on a different camera without issue. ![]() The change has only happened and only happens when I start working on GH5 4k footage. (1/2 the concert)ġ080p footage of all sorts never crashes Pr. This is reproducible at will.įootage is of concert 47 minutes long. The footage crashes Pr when I load it into the project and try and play/scrub it. and am still experiencing crashes with Pr and GH5 4k 8bit footage.
