Compressed RAW vs Uncompressed RAW on Sony A7IV

If Lossless Compressed is exactly like Uncompressed, why does Uncompressed even exist? It has to have some kind of advantage for it to exist, no?

Why do Sony ARW files come out looking processed (sat, contrast added)? My Canon cameras come out super flat.

That intro was CINEMATIC haha

Very useful when thinking of giving up on Canon to grab the A7IV.

For me I had some troubles importing my compressed RAW from A7 III. I thought Lightroom classic 2022 would uncompress the photo, but it didn't. I had to use another app to open the file. Someone here has a clue ? Thanks :)

the point of compress and uncompressed is when you shoot above 6400ISO, in that high ISO uncompressed files are much better then compress one, maybe you should learn before going YT tutorials, you are confusing other ppl with you lack of knowledge. cheers

finaly answer to my question. Thank you :)

Ha. i had to hit the like button when i heard "Father of four".
i am a father of one and learning photography.

Good video !!!
How about in the A7RV?

MAGIC!!!! :)

My light room doesn’t open these awr files. How am i supposed to edit raw if i can’t open it?

Thanks for the video and the files! I can tell the difference in quality, so I'll use uncompressed RAW! I can see little square pixels in the compressed and lossless compressed files, in the uncompressed files they look smoother, especially in the corners! Thanks again!

Thanks for the info!

PLEASE HELP!!... I RECENTLY DID A WEDDING IN LOSSLESS COMPRESSION FORMAT. I AM NOT ABLE TO OPEN RAW FILES. BUT WHEN I SHOOT UNCOMPRESSED THEN THEY ARE TOTALLY WORKING. ONLY WHEN I SHOOT COMPRESSED THEN I AM NOT ABLE TO OPEN OR EDIT THEM. I HAVE LATEST VERSION OF LIGHTROOM CLASSIC.

Very good review and answer my question

great! Thanks!

Literally bought an a7iv yesterday, 28 July, and this video is SO helpful and confirmed what I thought, cheers buddy. Subbed too 🇬🇧

Thank you very much ! I use A7 IV and I do exactly what you say : Raw lossless compressed except when I want 10 fps...and it's not a problem indeed !

I own A7R IV ver. A. There is no RAW lossless format. I'm wonder if "compressed" means the same as "compressed" in previous A7R IV? Is there also no difference in image quality?

That was helpful - thank you 😊🙏🏼

Thanks for your video, is really useful and well explain the difference between the two version of raw files. Despite I take different kinds photos (wildlife) I go for compressed raw files, because there isn't difference in term of image quality, and in wildlife photography is better to have a good shooting burst, for not missing any important moment.

Thank you for explaining this so well..you win a new subscriber....God bless you and your loved ones

Man that intro cracked me up so bad!🤣🤣🤣

Do you use 10FPS shooting weddings?

Deadly video! Great info, thanks very much and I love the t-shirt 😜

Brilliant video style as well. No useless shenanigans. Just straightforward information.

sony a74 give you uncompressed file 6 fps wich is extremely low for this price.

Dobra to teraz po polsku xd lekko skompresowany wystarczy xd

Very useful thanks a lot. To be honest the main thing avoiding me to by an A7 IV compared to a Canon R6 was the obligation to compress the raws to reach 10 frames per second. Now i can be more trustful 👍

Do you think upgrading from the Sony a7 riii to the A7IV is worth as a wedding photographer? :-)

U get a Abo fpr your Lego Intro - the rest is also very Inrteressting for me ;-) Thank you very much.

If we are using a 100 mm lens on a full frame camera , at what real distance will a 1 mtr long diagonal placed rod / stick will occupy the full 35mm diagonal of frame ??

thank you!

Hey man! Great video! I recently get a 7IV but i can´t previe the photos. Not even in Lightroom. Do you have any recomendation? I use a macbook pro. Thanks!

really useful video! thank you so much!

Super useful. Thank you!

Thanks Magic, that's a useful insight. Like you I always shot lossless compressed on earlier Sony models, a7riii, a7riv and a9. I'm in process of adjusting my kit going forward to start embracing video as well as stills. Sold all my bodies and just taken delivery of an a7iv. The idea of buying a a7Siii, although great for video, never seemed like a good idea for stills given just 12Mb.

As I also like shooting sport, my a9 was last body to go. Hence your timely advice..... 10fps RAW lossy compressed is essentially OK unless I screw up the exposure vs 6fps lossless RAW. If and when I can stump up the funds for an a1, then it's good to know one gives up little to get 30fps - not that I can imagine often having that need for most sports work (I'm doing for fun as an amateur, not professionally where I might need to explain why I missed a shot).

That said I'm genuinely puzzled as to why Sony would 'knobble' the fps down from 10 to 6 fps if there is so little practical difference between file sizes and compression algorithms? If it's the same processor as found in the it a1, then it's unlikely that the Bionz processor is causing any 'bottlenecks effect when calculating the compressed file.

Thanks for the confirmation that lossless compressed and uncompressed is identical as per what sony claims, I can shoot lossless without any qualms

Regarding the compressed RAW , maybe it would be useful to test those scenarios that broke compressed RAW on older Sony cameras...

IIRC multiple bright spots against a black background had rings in the bright-to-dark transitions

One example of this is fireworks

I am guessing a laser pointer spot in a black room will cause the same effect.

Hi Magic! It has nothing do to with this video, but could you make a video about how you make your evening shots at the parties? They look really nice with all the different light trails and double exposures. But I don't know how to achieve that with your subject still being in focus. Thanks!

Nice explanation!!

You should talk about the bit depths and how they change spending on drive mode and compression. You might get 12 but you might get 14 but.

Hello magic... I've just got my camera and don't have a lens, what do u reccomend

Amazing content, loved this. ❤️ Thanks

Awesome video and really helpful....just received my A7iv and its amazing but quick question how am I able to transfer raw images from the camera to phone because every time I try to transfer raw images from the sony app the images aren't able to open in gallery only Jpeg can. Or how do you transfer your raw images?

The question I have is are you considering moving from the a7r3 to the A7IV?

Thank you for this analysis. I've recently been bouncing between lossless compressed and compressed with my A1. Glad to hear I can stick with compressed and not miss out on much, but gain the true 30fps bursts.

Since the a74 has 3 custom mode slots, you could assign uncompressed to one slot and compressed to another slot.

Did you notice a slower post processing of lossless image file (let's say in Lightroom) compare to compressed image file ?
