I feel like inserting 128-256 Gb SD and forgetting the all thing for some month or two (more is better - for me, of course) still be sure that 2-month old video is still there and I can still access it. Just in case. Hope it explains my question.
H265 does not save much file size for dashcam video, and if it does then you lose image quality, it is not a reason to buy the V3. The image quality is the reason to buy the V3.
Depends on the content of the video, and if the codec is capable of variable bitrate.You don't lose image quality with H265 - it is able to compress the data more and reduce the file size, while maintaining the same quality as H264. The flip side is the playback device requires more processing power to decompress the H265 video for playback - not to mention a lot of legacy computer/devices aren't capable of supporting it.
Recorded some V3 footage at 1440p with default MP4 H.264 AVC compression and similar route using hidden H.265 HEVC compression. From these videos both have pixelation and what seems like soft focus or soft sharpness. The H.264 clips are 25.8 Mb/s and lower than I'd like. Seeking opinions which compression method looks better?

For dashcam video it will come nowhere close to the 50% file size that is normally claimed without a big loss of image quality.
My hardware ( computer & phone ) have no issues handling H.265, and i might give it a try like i also did with the Mobius 2
But i think in general i will keep with H.264 for day 2 day use.
My sisters budget dualcore laptop almost locked up when i tried to play H.265 on it though it is also a very old and very low budget laptop.
It's funny though, my Intel Core 2 Quad processor from 2007 will play H265 just fine. For that old computer, it's more about finding a player that can support H265 well. Potplayer on that old system plays it just fine, albeit with about 50-60% CPU usage, but it plays smoothly.
yes, but the point is in some cases the files may be required to be unedited which could be a problemWould it be possible to record in 265 then convert to 264 for third parties ?
The conversion from H265 to H264 should be seen as similar to the conversion from microSD to USB stick (or CD for Dashmellow), they would still be unedited. Same again for conversion from H264 to HDMI for display on a monitor. Of course your justice system might have other ideas.yes, but the point is in some cases the files may be required to be unedited which could be a problem

However I have yet to see a clear advantage from H265 when used inside dashcams so I don't think it is currently an issue, and since H265 is likely to be superseded by AV1 soon, I wouldn't even use H265 for archiving in case it became unplayable in future; AV1 does a better job for archiving anyway.
With 2 channel 4K using up a GB per minute, a CD is going to be about as useful as a floppy disk!There is no reason you couldn't have a conformed copy on CD...

Does this mean that we should only record original footage at 1080 resolution so that the original can be stored on CD and played on 1080 TVs that can't handle 4K video? Sometimes the legal system has to catch up!
