Sony A7IV 1080p vs FX30 4K 100fps! NOT WHAT I THOUGHT
HTML-код
- Опубликовано: 17 июн 2023
- I really believed that this was going to be an easy video to make because it is pretty evident that most 4k files are objectively better than 1080p files. It's larger and more detail and information. But what I didn't consider is the quality of the 1080p 100fps file in the Sony A7IV kept up with the FX30 4k 100fps.
There are a few factors explained in the video why this is. Namely the crop factor, oversampling, noise and digital sharpness.
What are your thoughts? Do you still film in 1080p for some things?

as far as sharpness goes, the 120 1080p is a bit better in crop mode too. Still it would be nice if sony included 4k120 in the a7IV even with 3x crop.
Love the channel mate! 👍I shoot weddings & was so impressed with the FX30 that I brought 3 of them for extra ceremony angles. 🤙
Love the comparison - I think just looking at the images side by side- the 1080p from the A7IV looked better. Thanks for always producing the great content.
I'm seeing this video on my 4k TV (49") and there is substantial amount of difference in sharpness between 1080p and 2160p. FX30 is way sharper than A74. Distance between TV and me is 10ft+.
The 1080p had so much more moire too. The FX30 is surprisingly good despite the crop and noise in 4k120, if there's enough light.
The a7iv in 1080p is much sharper when you put it in apsc mode. I think there is some sort of lineskipping in full frame.
I was just about to say this. I'm getting mine this weekend. The video is too good on the FX30
I’m in love 😍 with my FX30, and really, once you learn your camera, it’s all similar… it all still comes down to story, and cinematography. Oh, and the art of editing.
Love your work mate, cheers 🍻
Absolutely. FX30 is such a good all round video camera
Great comparison. As an Aussie living in Europe I really appreciate watching your videos and reviews Jason. Cheers from the Basque Country.
Thanks for watching! You’re in Europe while we are stuck all the way down here haha
@@JasonMorrisphotocinema Me too! and cheers also to Jonathan from Euskal Herria!
I’m an Aussie in USA, and watch Jason to understand in Aussie English.. haha
Jason, every time I see one of your videos I walk away feeling even better that I have the a7IV! I have never even seen one of these other models you discuss, nor know anything about them, but there is always in the content or in the comments several little "gem" tips that are complimentary to the a7IV. And that is certainly true of this video also. Thank you!
I heard that the FX30 shoots in 4.6K when filming in 4K 60fps. Personally, I didn't see a whole lot of difference in image quality between the two ISO settings. I think there's too much whining about these issues. When you consider that actual film stock has grain that is just as noticeable as noise from digital cameras, you wonder why people complain. You can remove the chroma noise in post in seconds with DaVinci Resolve with little to no hit to your rendering times.
People seem to want quality footage without having to do any work. As someone who has worked on 40 feature films as VFX artist, I find this "issue" to be a sign of laziness and not a valid complaint at all. These kind of videos seemed destined to pop up every year any time a new camera comes out. It seems unrealistic to expect every new camera to do everything for you with little effort on your part except setting the aperture and ISO. Considering the work I've done as a visual effects artist, hearing these complaints makes me wonder why people bother. If all you want to do is spin a couple dials on your camera and call it a day, maybe filmmaking isn't in your future.
My take away from comparisons of these two cameras is if you can afford it, get them both. With the two of these in your kit, there isn’t much you can’t do! I own both of them and when I’m on a shoot, if I can think of a shot I want, one of them will get it done! The FX30 has a definite film look to it and the a7iv compliments the video features perfectly. These two can do it all. My a7iv does the heavy lifting for photos, and is the B cam to the 30’s video. The FX30 does the lifting for the video side with the good variety of lenses I’ve bought for it. I run Sigma lenses for both cameras, with a couple specialty cinema lenses for some specific shots. In the future I will add another FX30 to my kit because there have been times I’ve needed 3 cameras on set.
Why not add an FX3?
thank your review so much
3:22 so if you wouldn't use it in high dynamic situation what would you do instead? Just got back from Iceland and I was filming in SLOG 3 at auto iso.. yeah I know and a lot of my film was grainy at night, had to find out late that was a bad move
Have you thought about using 1080p to avoid the overheating issues on the ZV-E1? Doesn’t it also oversample from 4K into 1080p?
I would love to see a comparison with that A7IV upscaled in post to 4k vs. the 4k120 on FX30
That is exactly what this is
Thank u for that short helpfull video. But one question:
"How can i go to 10bit with 1080 with my Sony a7IV appart the s&q?"
Hi Jason, this was such a good video. I wonder if there is any difference between 4k 60fps from an APS-C vs a full frame.. Can the APS-C hold the same image quality on a good light environment at 60fps?
I have a question. If I want to take a stills with these camera is better keep lowest ISO for clean image or is better to stay on base ISO 800 (FX30) for highest dynamic range?
The zebras don't turn off when you go into those lower ISOs. The clipping point gets lower because you're losing latitude in the highlights. If you set a custom zebra to lower limit, the clipping point at ISO 800 should be 99+. At ISO 400, the new clipping point is 97+, and at ISO 200, it's 93+
That can’t be true. I changed the values of the zebras and they were still not there. The light still was clipped and the zebras did not show
@@JasonMorrisphotocinema Really? I did it just before commenting which is how I know what the values are...
Watch Gerald Undone "Shooting Below Native ISO - Good Idea or Bad?" @ 4:41
@@JasonMorrisphotocinema are you using C2 zebras with Lower Limit? Just have to take it down 3 points for every stop you are below native iso I believe, most likely in the 70s somewhere.
do you think exposing the fx30 in 4k 30-60-12fps is best to do +2 to get the least amount of noise?
Wow this video couldn't come at a better timing.... Thanks
Thanks for watching
This is 👌🏼
The bennefit from FX30 is that sharpness & option to crop/zoom in postproduciton.
Hi Jason,
Thanks for the interesting video. I got my new A74 yesterday and after about 10-15 mins of setting up the menu, it heated up pretty strong. Is this normal? I didn't take more than 15 pictures and no video.
Thanks a lot for the reply.
Regards
Marian
I process the video from my Sony A7 IV with the Topaz Video AI program, achieving excellent video stabilization and an absolutely smooth full-frame picture at 59.94 FPS (having converted the video using this program from 29.97 FPS).
Great comparison. The A7IV is such an awesome 1080p camera, I'd say its even better in crop mode.
Like frame rates should be seen as a tool, using the appropriate one for the job. I still shoot the vast majority of my client work in 1080p as the smaller files makes it much quicker and easier to edit projects, and it's all the client needs.
Try 4k HS 30mb 4:2:0 10bit. It’s sharper than 1080p also less file size 😊.
@@lewcehjitl3282on the Sony IV? Any chance of overheating?
@@Jcruzcaptures no overheating.
@@lewcehjitl3282 with 4k60 4222 10b it does overheat for me around 30 minutes, do you know if memory cards make a difference with heat?
@@Jcruzcapturess far as I know they make very little difference. The biggest difference is flipping the screen out as you probably already do. And after that PD produces less heat than the battery alone and a dummy battery is best for overheating. This is from Gerald undone testing
With Resolves new upscaling option there is a very good case for shooting only 1080p with the A7IV.
Ofcourse. So good
explain please
Hi, what camera and lens did you use to shoot this video? It looks very good.
My oppinion that noise isn't everything when evaluating a quality of an image... does nobody see the moaire on the a7iv?
There is an aliasing problem with a74 100fps video((
Jason, I've watched a few of your videos now - great work and like your style. I could really use some guidance on buying my next camera. I've been a Canon APS-C & Z Cam user for 3 or 4 years but I think I need to go to SONY now to get better low-light capability along with strong AF & IBIS. The dilema I now have is, do I go for the FX30 as I'm used to some sort of crop, or do I spend double to get the FX3?.... or possibly even the A7S? I'm drawn to the Cinema Line just to have professional audio-in, as well as the cooling fan. Thanks. Matt
If you have the money you will find longevity in getting the FX3. Overall it is better for most cases
@Jason Morris thank you! I figured it would make sense to get the full frame but thought I'd get your opinion as you've shared a lot of positivity of the FX30. Cheers Jason. Best wishes. Great channel 👊🏻
Now start the canon vs sony vs panasonic vs fuji . I want to watch. Btw amazing video ❤
Haha nah I will never compared cameras brands. Way too hard and too many variables
Wow, the A7IV is very good at 1080. I didn't want that camera because of crop in 4k/60 but now i change my mind
Oooh, what a channel, what a find👍👍👍👍Thank you from the bottom of my heart. I was choosing between Canon r6m2 and Sony A7m4, I will take the sony.... Please suggest the top portrait lens (budget is unlimited) with the most gorgeous blurred background. And the second lens for shooting 4k travel video with the maximum possible quality and the minimum possible weight, that would for a day of walking around new cities shoulder and back said thank you)))
Thank you. 50mm f1.2 GM is my all time favourite lens
That shallow depth of field on the full frame camera is really hard to beat!
Good point. I own three Sony bodies including an a7iv and zv e10; I use the latter a lot because it’s so portable and, even though it’s not nearly as advanced as the fx30, it gives very nice apsc sensor results (ex here: World Bardo 132
ruclips.net/video/J9MilNRSWFM/видео.html ).
Nevertheless, I find the full frame sensor really generates beautiful results, and when I use the a7iv (that is, when I’m not walking around all day), find that even the 1080p footage it produces very pleasing.
hi! please make a video with the best settings for shooting cinematic videos on FX30
Wish Sony would fix the all-i data rate issue which gets you worse artifacts than long gop. I returned the fx30 because of that and the crop in prores raw. Why have all-i and raw when they are handicapped like that?
Is this only on the fx30 or is this the same with the fx3 / A7siii?
Does fx30 record sound when on 4k/120 or hd/240 at 10 bit? My a7iv does not record sound when on 10bit hd/120.
Fx30 does not record sound only in fhd 10bit 120/240
In 4K 10bit 120 you have sound
Really then, do you NEED to record in 4K? Seems like 1080p is self sufficient enough (plus space saving)
a7iv its a monster, need to correct the overheating and will be perfect, and for the prices will be better option than a 7siii also the fx3
*other then Crop factor I can't tell the difference, but I do Love shooting at 4K & 60 on my FX30 but I don't own an FF Sony.*
I’m new to all of this. I’m looking for still interviewing & minor indoor studio photography. Which camera best fits that?
A7iv for photo
If just video then fx30
Whatr external moniter do you use?
I don't have that camera, but I do watch your videos..I'm guilty of watching it on my cell phone and forgetting to hit like.
I liked the color better on the A7IV, they seem to be brighter.
Honestly, after youtube compression the "normal" vs "new", and other examples of noise look pretty minor...
Yeah RUclips compression really doesn’t show noise as it does on our own screens 😅
Please make a comparison between a7 iv and a7 r v
I’ve done this in my a7rV review
Fx30 vs A7IV which one better??? I don’t know. Let me decide.
Discovered 1080/120 with my a7c and was flored by the flexibility. I pull photos from videos so want 10bit 4k60, but if just doing videos I only need 1080
A7C doesn’t do 10 bit tho sadly
@@dirtcreature3d yep if it did I wouldnt be looking to upgrade. I really like the a7c. But I think an a7s3 or a7r5 is in my future.
@@soholingo yeah i still have my a7c, amazing camera still cant beat the form factor. I ended up upgrading to an A7IV when it came out and they make for an amazing combo
I noticed a difference in resolution when looking at the face. But if I wasn't looking for it I wouldnt have noticed it. I think the 1080p looked a little softer on the skin which could be helpful
Certainly could tell with the face
a7iv was in apsc mode or ff mode?
That chromatic aberration on the 24 mm on the FX30 is horrendous! Totally demolishes that video - Is that the ND causing it?
You have 120 fps and can go 240 fps on FX30. The FX30 has more noise because its a cleaner sensor. Let me explain. It has less in camera noise reduction. The noise is also detail, it cleans up nicely. I think the FX30 shines in low key scenes. It reminds me of the BM look
It’s noise because if crops in on the sensor and no downsampling. The SNR is higher and makes it a noise sensor
@@JasonMorrisphotocinema Yes, yes. 100K is noisy, but it can be cleaned in post. Also 200HD is nice
Does a7iv in apsc mode have better iso performance than fx30, jason?
Absolutely
Noise is my least concern nowadays. There are many ways to reduce noise even with AI. I'll chose resolution over noise.
I’m so new to all this. Noise is the vibrating of the videos? So the Fx30 has more noise?
I can't help but notice the small amount of moire in the A7 IV 1080p 100fps as compared to the FX30 at 4K 100fps (take a look at the eyebrows around 2:23 for example). An average non-filmmaker viewer will probably not care, or might care to an extent if it's pointed out
This camera offers a1.6 crop in 120p. So a 50mm lens will have the field of view of 80
The FX30 looked worse on the soccer field due to the lens... much more chromatic aberration. I.e., the crop of the crop is much more demanding on the glass. The difference in DOF doesn't matter to me... (FWIW), as I'm focused on what's happening with the subjects.
Oh yes. Certainly don’t compared the differences in lenses and focal length. More about the resolution and overall quality
Can Fx30 shoot 1080p 100fps?
Yes
Didn't expect that 1080p from a7 iv will be so close to FX30 4k with details... disappointing
Instead of always shooting in log, I changed PP10 so that it uses slog3 gamma and s-cinetone colors. Best of both worlds! Have you tried that Jason?
does that actually work? i've watched videos about that and they usually end up saying its not worth it.
@@HoshiASMR I like it, still get a flat image for exposure but with all the colors so no extra saturation is needed once you get the exposure adjusted properly. That being said, I haven't tried adjusting PP11 to see if I can get the same results without adjusting exposure values.
Everyone looked a bit wider on the FX30…..is that just me?
It was hard to match focal lengths with prime lenses. It’s about the image quality not for field of view
@@JasonMorrisphotocinema ah good to know. Thanks for a great video as always.
Happy Father's Day!! Today my 30 dollar camcorder comes in!
Hahaha what a win! Happy Father’s Day to you too
@@JasonMorrisphotocinema I am reviewing it on my channel and I will be mentioning how you talked me into it lol
You explained it yourself, there are two very different imaging scales between the two cameras with the same lens due to the cropfactor 1.5 sensor size + 1.6 of the APS-C-100p sensor scan. Your attempt to be fair didn't quite succeed, because at 3:52 your friend's head size was imaged about 20% larger at 4k-100-APS-C than at 1080p.
With my IPad and data rate, I see both test shots in 1080p.
At APS-C 2:08 there was more depth of field, more parts of the face between the eyeball and nose were sharp. This subjectively gives a sharper overall impression of the image, to avoid this you would have to stop down the aperture on the A7IV 1.4 x 1.5 = to 2.1 x 1.6 = 3.36 = about 3.5 and set the APS-C to 1.4 to account for the overall crop factor of 2.4, then the impression of sharpness and the S/N would be fair to evaluate at the same image size and speed, correct? Please correct me if my calculation is wrong. It would have been nice to have all shooting data like distance between object, eyes and image plane superimposed on the image. The lens has a distance scale, what is the formula for the distance setting so that when displayed full frame on the screen, your friend's videotaped face is exactly the same size at 4k-100 APS-C format-filling as it is on the A7IV in HD 1080p?
Your video is very elaborate and instructive, thanks for that. As an amateur I'm interested in the formulas, maybe you could include them in the accompanying text or as an answer?
I’m not comparing depth of field 🤦🏽♂️ I’m comparing resolution and quality of image
No such thing as depth of field with super 35. It’s just because you had a 24mm lens vs The compression of a 50mm
Even tho it’s super 35 the crop still doesn’t makes up for the compression.
Because a 24 mm compression is not a 50 mm compression it’s like using a APSC mode on my A7rv. The reason why I wouldn’t get shallow depth of field. It’s not because of APSC it’s because of the compression of my lens.
Conclusion you could get shallow depth of field with Apsc matching the same full frame
This video isn’t about field of view. It’s about the image quality
@@JasonMorrisphotocinema no I know it was because you were saying APSC has no depth of field as much as full frame. Unless I’m wrong brother
@@Framesbyfrisby when focal length is equated. Listen to my whole sentence. I know depth of field is aperture and distance to subject
You’re missing the whole point of the video
1080p is King.
FX30 4K looks clearly better IMO
Definitely in close ups
Could you speak faster
I think you're nuts. 4k is obviously different, 🙄
FX30 is so green 🤢
