Video from the C23 and H Plus

I found this in the online manual for the H520:
Yuneec recommend using a SDXC Class 10 UHS-3 micro SD card for recording 4k video. Using the UHS-3 card allows the camera buffer to record to the micro SD card faster resulting in less buffer overrun.
So far, there is no recommendation in the H Plus manual although the similar spec of the C23 vs E90 suggests that the same recommendation should apply. Maybe it will appear in a later version of the manual…or maybe it won't if there is any doubt about the capabilities of this card under maximum write load.
Has anyone checked the actual bitrate of the C23? I remember a bit of a riot when the H was initially advertised with 100Mbps and then adjusted down.

Thanks , YuKay! The camera still looks good in all of these. Obviously the last one had some lens flare but that’s not unusual. Perhaps with the H+ a lens shade may eventually be available from an after market source.

At 4k it records 100mbs at lower resolutions the bit rate is lower. The card that comes with the c23 is the same card that comes with the E90 class 10 u3 and is fine at 4k 60fps on my E90

I think that recommendation is for a U3 card which is the same as what we’ve been using with the H.
Yes Ron, I liked them all - although I didn't like the blocky artifacts/posterization in the gravel surface the car is parked on at the end of the bridge video…even though the camera is moving very slowly. I may have to come to terms with the apparent fact that the C23 (and maybe every other similar camera) doesn't cope well with the extra detail in that type of surface texture. Sand mostly looks OK. Pebbles mostly look OK. But <10mm gravel is a no-no.
Thanks Kev. Do you always shoot RAW or do your comments also apply to Natural and Gorgeous (or whatever these are now called)? I ask because the less in-camera processing, the better the SD card should be able to cope (which might scupper my dream of "nailing it in the camera").
Indeed Ron, I'm just waiting for Yuneec to put in black and white…or have they already published it somewhere for the H Plus?

I try and shoot everything in Unprocessed it's called on the e90. But have also used Natural with no issues when I needed to give a client the video file straight out of the camera. I've even used an older class 10 u1 SanDisk card, again with no issues when I've been running low on memory cards.
You gotta like that!
YT "Stats for nerds" only reported 4K30fps. However, the pans looked smooth enough that I could believe 60fps.
Kudos to Helicomicro in France for as comprehensive an upload and review as you could wish to see. The 7min 4k60 video has just about everything with a wide range of shots, angles, close-ups, speeds and pans (some of which may make you too feel a little seasick). The video links to a website for a multipage review (use Google translate) with dozens of photographs - and there are also links to a number of interesting downloads including video clips comparing H.264 with H.265, still images (including panoramas) and the full uncompressed video file. Here's the video:

And give Monsieur Helicomicro a big thumbs-up! The H Plus was a loan from Yuneec but he has been impartial as far as I can tell.

Thanks, YuKay.
Unfortunately my knowledge of French is limited to “Laissez les bons temps rouler” and the “Tour de France”.
When time permits I will endeavor to decode pieces of the review with Google Translate.

It’s not too bad.
I leave French to my wife’s niece who has a PhD in French, music and translation from an institution in Paris.
I used to speak some Japanese. I know enough Russian to know when to duck and how to insult people.
I’m relatively fluent in American English.

Yeah but what about English English Ron [emoji23][emoji23][emoji23]

For reading the article, apart from a problem of video retransmission (due in my opinion to an antenna defect), the tests are conclusive. For information, the testers are not specialists in the production of photos or videos.

Oliver, did you download the files? I am interested in the H.264/H.265 comparison clips and opinions on their respective quality (bearing in mind the C23 can't record 4k any higher than 30fps in H.265).Google translate is my friend when I try to understand you

I am also curious about the comparison clips being identical in subject/framing. Is the C23 capable of recording both H.264 and H.265 at the same time? How else to get identical clips?
Moi, je parle francais comme une grenouillère.
@YuKay I did tests with my H265 once, no significant difference. I only shoot in 264 to have the 50p and be able to edit more easily on video editor, because the H265 requires more resources when working with effects and on multiple tracks.
For me, the 265 brings nothing, except for smaller files.

Comparing the clips side by side, which I have never done before, I would favour H.265 for being warmer, richer and less aggressively sharpened than H.264. I assume it's the sharpening which makes the H.264 a little darker and also 5-10% bigger in file size.
