Sony a7siii which codec will I be using and why

Which sd card you were using at the time of this video made with your old computer . For XAVCS-I which sd card you use and what time lenght recording time will you get? I have a old computer and planning to buy an sony A7siii but Iam concern if will be able to work those files in my computer specially iam planning to do weddings... thank you for your help...God bless you

Is there any way to see how many minutes left for recording video ?
I mean ,if i had 128gb sd card and shoot at xavc s i 10bit 422 at 25fps for example,can i see at display how many minutes i have for recording????
(xavcs i recordable time)

Great vid, thx! So is HS format higher quality than the S codec? My computer (M1) is fast enough for both. Also is the S-I much better quality than HS? (don;t care about file size ;))

I find that I'm skipping frame rates with XAVC S 4K on my imac 2020 but it's perfect with XAVC HS 4K...any ideas why?

can u playback 4k120fps in camera's screen?
can u playback 4k60fps in camera's screen?

So specifically for a 2013 macbook* pro 16 GB ram, 2.8 ghz i7 what would be your recommendation?

why not use xavc s? a lot of pro users are going to that one as testing it vs the all intra codec is showing no real noticeable difference

Love your channel! Great video, I am on the lates everything including M1 MBP. My final cut will not accept my MP4 files from my a7siii? Message says the document could not be opened Final Cut Pro cannot open files in the “mpeg-4 movie” format? Any ideas? Thanks in advance!

Thanks

What about id you use xavc hs and edit with proxy?

hei man great video....but what do you think using the XAVC S 4K? I have a powerful mac so it is good quality the image of this set up? you also can rec at 100fps european

That's weird. I'm on a MacBook pro-2019 specd out, and the only one that runs somewhat smoothly is XAVC HS 10 bit 420. Everything else frame drops like crazy!

For best quality, would you use H264 or H265 at the highest bit rate?

SI is still very large files. I’ve found the S to work just fine with just as good of picture as the SI

The 2019 and up MacBook pros & the 2020 iMacs with the upgraded graphics card have encoding for H.265 420 10 bit and should edit smoothly. However nothing has encoding for H.265 422 10 bit atm, besides those iPads. I edited Fuji XT4 H.265 420 10 bit very smoothly on my 2019 MacBook Pro

100th Like!

Hi, what’s your MacBook Pro specs for running the XAVC S-1 smoothly?

I just purchase a use early 2013 MacBook Pro!

I don't have a SD card that can handle XAVC S-I, and a V90 card seems hard to find at the moment/expensive. Would this be an east solution? Use 2 cards, card 1 set to XAVC-HS, card 2 set to record proxy files.

I got this hint from Max Yuryev. The biggest thing slowing down editing in the 4.2.2 not the H.265. Computers built within the last 2-3 years have encoders and decoders for h.265 that help out quite a bit. When you use the 4.2.2 the GPU won't help you process the editing. 10 bit and h.265 isn't much of a problem, but the 4.2.2 is making my laptop really struggle and my desktop slow down quite a but I'm using Windows 10 though. After watching Gerald Undone's video about 4.2.2 vs 4.2.0 he shows it is almost impossible to tell the difference between 4.2.2 and 4.2.0. The big difference is 8 bit vs 10 bit. So try using 10 bit 4.2.0 until you have a better computer.

Great Tipp, David. Just wondering which cards you’re using for the XAVC S-I codec?

You need to use the 4:2:0 10bit h.265 at 100mbps for best decoding speed and good quality. The 4:2:2 version is not hardware accelerated, that's why it's so slow on your Mac. There is no visual difference between 4:2:2 and 4:2:0 (look at Gerald Undone's tests -- no difference), but there is a huge difference in decoding. I wish people stopped going for bigger specs (in this case 4:2:2) and instead knew how to read those specs: neither AMD nor nvidia support 4:2:2 hardware decoding in any format (they only support 4:2:0 and 4:4:4). So 4:2:2 is a bad choice for editing. Not to mention that 4:2:2 requires 20% more bitrate than 4:2:0 to be of the same quality, and Sony simply doesn't give you that at 100mbps (it's not enough bitrate). Also, only the iOS chipsets decode 4:2:2 in hardware, and the brand new Intel laptop gpu (that most editors don't support, and it's still not widely available). So unless you're editing on an iPad with Lumafusion, avoid 4:2:2 like the plague. h.265 10bit 4:2:0 will decode fine on a modern Mac/PC, and 100mbps will be enough for good quality. Avoid 10bit 4:2:0 with h.264 at 100mbps, it's too low quality to cram 10bit at 4k in that bitrate with that old encoder. h.264 in that scenario is only good at 4:2:0 8bit at 100mbps (and only in HLG3 with rec709 color mode -- in slog2/3 you will be losing bits in 8bit).

Convert to Pro res and you'll be fine. you can keep the nice high bitrate and easy to grade 10 bit 422 and get a lot ore latitude from this.

what a camera so many codecs to choose, I just did a video test comparing file sizes & cpu temps = h265 is way too heavy to edit

My amd 3950x should be plenty enough to handle these x265 codec I’m hoping

Aren't you supposed to be able to shoot 4k 120 in the XAVC S-I mode with the cfexpress card type a?? Cause all I can shoot is 4k 60. I have the 160GB version. Thanks.

I'm surprised you aren't using your Ninja V with the A7SIII. Ninja V has false colors, and waveform. Also, Prores is much better to edit.

I noticed on my A7siii that both XAVC-HS and XAVCS give me about the same amount of recording time. Given that XAVC-HS has more efficient compression, does that mean it is also higher quality?

Great review how about 4K 120 in 2 years old computer. I’m still waiting for my Sony should be here Friday

do u need the cf express card with this codec. thx

I'm loving these short practical videos on the A7siii, even though I'm still shooting with Olympus cameras. Early 2021, Sony, probably. Excellent work, David.

Thanks for the informations! Just testing around with these codecs! This camera is a beast!

The only reason to use the h265 is to save space, you're not going to get any better quality than with h264, in fact, it will probably be a bit worse due to the more aggressive compression.

looks fascinating all the different codecs..

One Sony E mount registered in China. Check out in Sony rumors. Sony doesn't say Sony a7iv will release 2021 Q3 just by others people.

Computers are so far behind cameras tech Seriously it's not funny. Just goes to show you, Computer manufacturing are not involving before the manufacture of the cameras. Cripple hammer apply to PC laptop too lol

I so wish I I could afford this camera right now...a7iii has been treating me good at the moment so let's see what the a7iv will deliver as far as video upgrades to the a7iii

I'm gonna start saying codacks now too!!
