FDR-AX53 XAVC-S 4K - "jerkyness"

clarkerz — Sat, 02 Apr 2016 17:49:51 GMT

Hi,

I have just purchased a FDR-AX53 from Jessops Cardiff on the 1st April 2016.

I am having trouble with JerkyNess when using recording movies XAVC-S 4K at both 60 and 100 mb/s. The quality is stunning but the jerkyness makes the picture annoying to watch.

All HD recordings are perfect and faultless. I have put 5 different tests here on YouTube and I'd like your thoughts on why it is "jerky". It's as though there is some sort of video processing being applied but I cannot see where to switch it of it there is. I really don't want to have take the camera back for a refund so hope this is resolvable.

Thanks

Hi,

I am expecting delivery of this camcorder on Wednesday so it is somewhat disheartening that there are issues with 4K already. I know that the older 4K models did not appear to process the footage quick enough which gave the appearance of 'jerkyness' during panning - see this thread https://community.sony.co.uk/t5/camcorders/fdr-ax-33-panning/td-p/2004676

This camera has an improved processor and fast intelligent AF so one would expect better results ?

Sadly I read this on page 139 of the user manual regarding frame rates:

Available frame rate settings

XAVC S 4K:

30p(*)/25p(**)

24p(*)

XAVC S HD:

60p(*)/50p(**)

30p(*)/25p(**)

24p(*)

AVCHD：

60i(*)/50i(**)

60p(*)/50p(**)

24p(*)/25p(**)

Descriptions of menu items

60i(*)/50i(**):

This is an ordinary setting for recording AVCHD movies.

60p(*)/50p(**):

You can record movies with a data volume twice that of 60i(*) or 50i(**)/30p(*) or 25p(**) per

unit time. When you play a movie recorded with this setting on a TV, the TV must be

compatible with 60p(*) or 50p(**) movie playback and you have to set [HDMI Resolution] to

1080p.

30p(*):

It is recommended that you use a tripod when recording movies with this setting.

24p(*)/25p(**):

You can record movies which provide an atmosphere closer to that of film images with this

setting. It is recommended that you record movies with this setting using a tripod.

Please note the section in red, as the only frame rate for 4K available is 25p (for a UK model) it would appear Sony recommend using a tripod ? If I am right then this is not great. Sure, they have got full HD sorted but 4K seems a little more challenging.

Personally I hope you can recover the issue through the camera settings, the footage does look good. I have purchased two of the following - SanDisk Extreme PRO 64GB SDXC UHS-I/U3 Memory Cards up to 95MB/s - which is the least that the user manual recommends for 4K 100Mb/s

It might be worth switching off the dual record function, that is if you have it enabled during 4K recording ?

Please let us know if you sort this out - sorry I cannot help any further

Regards

Hi,

Did you resolve the "jerkyness" issue ?

I have my AX53 now and I am very happy with the results. I must say that I updated the software here

before I first used it. This update would not have been available to you at the time you posted this thread.

I recorded at 4K XAVC S 60MB/s and played from the camera through the television, I think it is brilliant !

I have reviewed the camera on this and Amazon web site.

Regards

Jonnie, Which Memory Card do you use for your AX53?

So it works in 4K

Hi,

Sorry for the late reply, I have had trouble getting my account working !

Here is a link to the memory card that I have used: SanDisk

As long as it is 25 P you wont be able to resolve it. I dont use 4K when i am moving/panning and the result is more than good enough for my eye:)

Hi,

I'm very disapponinted in the AX53.

I was looking forward to this model because of the promising huge marketing.

These are only part of the BASIC DEFECTS... (To be continued)

Nobody can help because new repair software is not yet.

I'm a practised user working as a cameraman/director.

I worked for 3 years with the former SONY model HDR PJ740VR.

@CSABA53

Hi,

I appreciate your work as a cameraman. I am in no way a professional but I think the AX53 is brilliant. I am sure if it is as bad as you say I would notice these issues also ? Just a thought but have you wondered if your camera is working properly ? It may have a fault ?

Hi,

You saw the tests, didn't you?

Problems need correcting with a new software update!

Otherwise, this model WILL BE great.

The sooner SONY realize its error, the better.

I have just learned that if you mount the FDR-AX53 on a Tripod you cant turn on the Boss system Stabilisation and if you zoom while on the Tripod the footage is very Shaky,so i cant use a Tripod.

I myself use the SanDisk Extreme PRO 64GB SDXC UHS-I/U3 Memory Card up to 95MB/s Read FFP (SDSDXPA-064G-FFP) also the Lexar Professional 64GB Class 10 UHS-I 633X Speed (95MB/s) SDXC and ive had no Problems at all.

I have to admith that I bought an AX33 and I am quite disappointed withthe results as regards the jerkiness at the highest deifinition. I have found that transcoding the video on download to "optimum" (I use FCP X) helps if this option is available to you

Re: FDR-AX53 XAVC-S 4K - "jerkyness"

kcjones1313 — Mon, 18 Jul 2016 09:25:09 GMT

I would imagine that this might help with the AX53 as well

Do you have the FDR-AX33 or the Sony FDR-AX53 as you mention the AX33.

I too am having this issue and I'm not very happy about it. It renders the point of a UHD video camera pointless to me, as it can't be used without a tripod. I'm using the SanDisk 256GB Extreme Pro SDXC 170MB/s, so it's well capable of image capture. Exporting from Davinci Resolve 17 solves no problems (even after transcoding to DNxHR [which seems to be a recommended transcode format] it doesn't help any).

I've not tried FHD yet but reading through the forum it seems to be fine, which is always something.

This line of product shouldn't have got past testing IMO (for UHD at least). Guess I'll have to get a RED camera instead now.

Yes playback direct from the camera to TV is good and no jekiness. Why is there jerkiness everywhere else you put it though? Can't edit the footage smoothly.

When I got the very latest Firmware Updste it fixed it.
