  1. I would agree with this. If very cold ( or fairly cold ) air could be forced into the Memory card area ( Memory cards are removed ) some this cold air should flow past the CPU. My experience ( as an engineer ) is that even a slight amount of moving air across the top surface of a chip ( cpu in this case ) will have a significant cooling effect.
  2. Yes you are right. To prevent too many write cycles the timer would have its count value written to the non-volatile memory every, say, 2 minutes. At this rate the 200,000 max write cycle would take a 277 days of continuous use to reach the limit. It it is assumed the camera is in use, say 4 hours, of every day then the limit would be reached in 4 1/2 years.
  3. I am retired now but have experience over many years as an electronic design engineer. If there are 'timers' employed in the design then it is likely they would 'reset' to a zero or starting count state when the power is removed and then returned to electronics. This would occur when the battery is removed. for a short period.. However if Canon was clever they could continuously write the count value of the timer(s) to a non-volatile memory and when the power is resumed ( after battery removal ) the values of the count stored in the non-volatile memory could be returned to the time
  4. It should be noted that 720x480 is 1.5 to 1 , and 640x480 is 1.333 to 1. So converting from one to the other means black bars must appear somewhere if you don't stretch the original image. I have converted some old SD interlaced footage in the PAL format. An some of it was widescreen PAL where the pixels are nowhere square ( can't remember the ratio ) but the result is a 16 by 9 image from SD which has ( in PAL ) 720 x 625. I wanted to put my old footage ( family movies etc ) made on a DV recorder ( PAL) into a non interlaced ( ie progressive ) format which I felt would be more futur
  5. A couple of days ago, I down-loaded the beta version of Topaz Megapixel AI to my PC ( Windows 10 , i7, 16GB ram, GTX650 Ti graphics card with 2GB memory ) It is free for a 30 day trial. I tried some sample clips - process was painfully slow. To render a clip 1080 30p which was 1 minute long was going to take 7.5 hours. I have some clips made 12 years ago of my grandchildren. 640x480 15fps . I have managed to up-scale these to 1920x1080 30fps in Resolve 15 and get improvements The stabilizer seems to reduce jerky effect of 15 fps and produce something which is better to view
  6. I tried to install PotPlayer and it put a virus on my PC . My antivirus software ( McAfee ) fortunately stopped it.
  7. I don't have a GH5, but some time ago, I downloaded some original footage from the GH5. It was 4K h.264 10 bit 422. I don't use premiere or FCP . I do have Davinci Resolve and some other editing software. I tried to edit ( grade ) the downloaded original footage , but nothing would accept it. I can play the original footage with VLC and MPC-HC video players on my windows 10 PC. I used HandBrake to transcode the 4K h.264 10 bit 422 footage to 4K h.264 8 Bit 420. I can now edit the transcoded footage in Davinci Resolve and a number of other video editors. Of course the advantages
  8. I think a lot of people with their new GH5 will have problems trying to edit their 4K ( UHD ) h.264 4:2:2 10bit files. I downloaded the latest version of DaVinci Resolve 12.5.5.026 and it will not recognize this file. My Windows Media ( Windows 10 ) will not play this file, although other video players such as VLC will.
  9. Thanks Neumann films for the original GH5 files. It is interesting to have some h264 files with 4:2:2 and 10bit . I guess this will become much more common in the near future. I also found these were not accepted by Davicii Resolve.
  10. Today I discovered H265 HVEC files will play on Windows media player without any problems , this includes 1920x1080 50p, 3840x2160 25p, 4096x2160 24p ( all original files from the NX1 which I downloaded ) . I have windows 8.1 on my pc. There must have been a windows update in the last day or so for this to happen. I also can play H265 HVEC files which I have converted using Handbrake from various H264 coded video files. Note all of these H265 HVEC video files will also play on the MPC-HC player. ​Good to see support trickling out yet further. What spec PC do you use? My PC is Intel Core i7-3
