Computer stutters playing X-H2S footage

Hi all,

I am experiencing issues playing video captured on my X-H2S on my computer. I can open the file (with QuickTime), but the video stutters massively (like 1-2 FPS) while it plays. The fan also kicks in immediately so I think my computer is having a hard time with the file. I have the same issue in VLC.

I record in these settings on my camera:
4K 16:9 60 fps
H.265 ALL-I 422 MOV, 360 Mbps, F-Log2

My iMac has the following specs:
iMac Retina 5k, 27-inch, 2020
3,8 GHz 8-core Intel Core i7
24 GB 2133 MHz DDR4
AMD Radeon Pro 5500 XT 8 GB

I bought the camera because I want to create long recordings with high quality (hence the above HVEC settings), but is it normal that I cannot playback the videos? I'm sure my computer is not the fastest out there but a year ago it was the highest specced regular 27 inch iMac.

Thanks a lot!

What you are experiencing is not unusual.  Try this:

Download Davinci Resolve--a very powerful free NLE.  Then, create proxies or optimized media.  Optimized media is a ProRes file.  Tell Davinci Resolve to use the either proxies or optimized media.  Then your files will play back fine for you to edit--I did this on 2016 MBP.  To save space, delete the optimized/proxies when you have completed your project.

If you do not want to create proxies or optimized media you will need a new computer.  The M1s work great.  I have a MBP M1 Max and it works great with H.265 All Intra 720 KB/s files created by my X-H2S.  No proxies or optimized media required.

Hope this helps.

Don

      X Raw Studio works with image files on your computer - not the image files on the camera card

      Hello. Thankyou,now Is all more clear: I have take some time in your link. Let tell you. I has totaly forget this machine have "compress picture option" and not Only "compress lossless" anyway not change the experiment. RAW  and this last two format look like same result about Number of recording picture. Can tell all results in this: in raw you can make 17 pictures for second. Is wrong. Is about One single Press and wait buffer. Full 30/20/10/8 not change. After 17 Need Press again. You not can Press before "redgreen light recording Is on".   With preshot you can have 25  are more 7 pictures . The story change Only in jpg shot only. In jpg at 30 you have 30 picture but redgreen light off very Fast so you can shot very quicly. At 20 shot Is about start look like infinite shot. 60. So the best performance are this last One  about Speed and recording picture after camera working witout big limit. I want take a shot about Italy cyclet Just for passion. I think i Will use this last setting.  After Need check when battery not are full change and ambient temp.  Anyway my cam look like exactly specific about you link. Im Happy my cam working perfectly.

      I do not use Flickr, so I do not know what their BB code is. All I did was copy the second link you provided, (starting at https: and ending at  _k.jpg — leave off the [img] and [/img] tags) and pasted it into the message. After a moment, a message popped up asking if I wanted to paste it as the image or as a plain link. I did this twice, the first time I had it paste in as the image and the second time as a link. Nothing fancy or tricky.

      So do I just copy the BB code from flickr and paste it anywhere on the page like other forums or is there some other trick I need to perform to get it to post?

      All software is the latest between camera and app. All settings are correct on camera. I have both lossless and uncompressed RAW files on the card in the camera. I have been up and down every reddit thread to no avail and am losing my mind… I’m doing all of the right things. It even sees my camera. It just doesn’t create the “drive” for it (see attached image screenshot).  Please Help!
