Can anyone say if when recording in 4k50p after 20 min you must wait or you can start immediatly to record again

You can start immediately but the camera gets hot in 4K50 mode, I had heat warning at 25 mins when I last checked it. I think it's advisable to wait.

I just bought the camera and did the following test: Recording time regarding heat

Room temperature of 17 degrees: 80 minutes in 4k 400 mbps LongGOP (two 128 gig cards) without a temperature warning. I had to change the battery at 40minutes. For the second battery, I also plugged an old battery bank: Sony CycleEnergy 10 000 mAh that outputs 5 volts in standard usb 2.0. I used a USB 3.0 to USB-C cable to connect to the camera. Because the battery bank outputs 5 volts and the camera would rather use 7 volts, at the end of 40 minutes, I had 15 % loss in the battery inside the camera. So I believe using old battery banks are a good option.

I would not hesitate to use the camera for captions in shows or long interviews.

For 400 mbps recording, I made the mistake of buying 128GB cards rated V30. I can record but when I try to playback the files in camera, I get a read error. When I play the files on the computer, they are fine. When I record to 200 mbps, playback is fine in the camera.

I think it only records fine because the camera has a large buffer (for 30fps stills shooting).

Noticed a strange phenomenon today, when using the touchscreen to pull focus in video during recording, in AF-S mode, a touch would only half focus on the subject (focusing starts slowly and stops midway). In AF-C mode it works wonderfully though, locks dead on almost every time. But AF-C focuses everywhere the focus box goes and does not offer much control vs. AF-S.

Anyone experiencing the same?

Yes, I have the same problem, didn't find a solution yet.

Some color grading to  test the H265 10bits codec :

Very strong codec  (but a few moiré on the pullover).

You should have tested in 4K. the 1080p mode on X-T3 (and on most cameras these days) is not supersampled. It's a combination of line-skipping and pixel-binning, hence the heavy moire.

You're right. I will test 4K for moiré. But for my work (short fiction) I don't need and I don't want 4K. Too much resolution and big file size.

to the lucky ones that have this camera, is there a big difference between the internal 420 and the external 422 ?

 

Actually there are two aspects to consider for external recording:

1. 422 instead of 420. 422 is beneficial for intense colour manipulation and/or VFX such as keying and compositing.

2. Minimal compression with robust codec such as ProRes/DNxHR. It's very easy to edit/playback in real time. Image quality wise, the difference between external recording and internal 400Mbps HEVC ALL-I is minimal in low to mid ISO. In higher ISO settings combined with low key lighting and/or high detail scenes, H.264/HEVC tend to break apart and shows more blotchness. ProRes HQ/DNxHR HQX are able to retain fine noise patterns for easy clean up in post.

I have this one and it is excellent with my X-T3.  No problems at all. I had two Sandisk 128 GB 90 MB/s cards rated at V30 and I was getting read errors when shooting 4K video at  400MB/s, so I returned those and got a V60 rated card: https://www.amazon.com/gp/product/B079NQLYHL/
