BUG:

After recording a video—during, every thought is okay—the image stays upside down when I change between the font and the rear cameras, after save the file. Start the video correctly, but after changing, it turns upside down in the other camera(s) and returns to normality after I return to the original camera.

I desire its solved in 1.3 version!


This is still relevant in 2024, having exact issue with 1.500023 version.

This happends during mid recording session. So if you try to vlog yourself with front camera, then switch lens to wide angle - it displays everything correctly in UI, but record wide angle foorage upside down :shock: .

This happens only in Landscape mode (most useful mode!).

No settings help to fix that, tried all possible combinations. Please fix!

The crazy thing is: If you connect the Wireless ME via TRRS-TRS-Cable (and Apple Adapter) to the iPhone 15 Pro Max you can control the audio level inside the Blackmagic Camera App. But via USB-C there is no audio control inside the App. What I still doesn't understand: Then using GainAssist in the Rode-Mic, should I use TRRS or USB-C? Do I need to control the audio level inside the app or don't I?

Hi all,

I've updated to v2 as I have an iPad Pro - thanks BMD to add support for it!
I would love to remote control an iPhone 12 from the iPad, I set up the apps and it works. But, the remote feed on the iPad stutters badly when I am recording on the iPhone. The iPhone seems unaffected.
The same happens if I use the iPhone as controller - the remote feed on the iPhone stutters.

I doubt it's the wifi as the same remote feed works fine when NOT recording. I don't see mention of this online, is it just me somehow?

@Tony, likely a resources issue in the phone.

Turn off the auto generate proxy operation in settings and try again.

Thanks Peter.

That is Media/Record Proxy, right? With that disabled, I don't have stuttering. Does that feature mean that the phone is recording AND generating a proxy as well?

Is there a manual available for the phone app? I cannot find it.

Thanks for your help.

Hello I am having an issue with custom settings on a Samsung S22 Ultra. I have basically everything manual mode screen shot for settings.
I'm basically getting a weird dark flickering around the video like a vignette.
It only seems to be happening on certain camera lens selections. particularly the 67mm one.

Great app and definitely better footage quality than the stock phone app but this bug or whatever it is renders the app useless for me.

YouTube video link here for an example of what's happening.

I just started using /experimenting with the BlackMagic Cam app on an iPhone 13. After shooting a clip, I tried to edit the note in the info section. Rather than allowing me to enter a string of characters, the only allowed one character to be entered before exiting the field. It was like I had pressed enter (DONE) after typing each letter.

I'm using the Android 1.2.0025 version of of the app on a Samsung S24 Ultra and am getting constant frame drops when attempting to record to either external or internal storage.

Here's a demonstration of the issue:


This happens even at 720p h264 with proxies disabled.

After switching to Rec.709 and making sure stabilization is off it still has the same issue.

I also did the test with screen capture so you can see it here:

I would call this a bug using the v2.0...016 version on iOS 18.1 public beta.

Using Apple Log and when selecting Display LUT Rec.709 but NOT selecting 'record to Clip':

I see the LUT before recording and when playing back media, but the LUT goes away when I record so that my preview during recording looks like straight-up Apple Log (washed out), which is worse for monitoring what I'm filming.

I fully expect a Display LUT to always "be on", regardless of if I have "record LUT to clip" set or not. The record to clip effectively burns the LUT into the recorded file, I assume, which I don't want.

It's great that the Blackmagic Cam app offers so many ProRes flavors!

However, many tests show that the h.265 codec is very efficient, and most likely preferred in a large range of scenarios for casual and professional shooters alike.

The h.265 bitrate is dynamic, which is fine—increasing the efficiency even more. Tests of simple targets such as clean color ramps show that the bitrate can dip very low in 4K 25 fps such as 2.9 Mbps with a more typical bitrate of maybe 40 Mbps. For reference, modern drones go well above 100Mbps for this resolution.

What happens in "simpler scenarios" (less detail) like skies, large areas of darkness/shadow during night time, or interior shooting is that macro blocking shows up too soon.

I don't want this to be a reason to shoot ProRes with 16x the file size.

Would you please consider including at least ONE high-quality h.265 bitrate setting? It could still be dynamic, but should never go below maybe 20(?) and be allowed to go as high as 150(?)

Ideally, I'd like options like Q3 (50), Q20 (120), and Q50 (200).... maybe 3 in total where the current default is the lowest quality one and the number in the name is the lowest bitrate of that 'mode'. The numbers in parenthesis are the imagined top-end bitrates, but they don't have to be in the names.

In Cinema P3 you can increase the data rate for HEVC to a maximum of 200 in 5 steps.

Can I check if the below is expected behaviour?

When using the app on Android (Pixel 9 Pro Fold, which I am aware is not yet supported, but it seems to be working mostly fine so far), in portrait orientation without vertical video enabled, the viewer seems to be a centre cropped version of what you would see if you *had* vertical video enabled rather than the full width video of what you see if you rotate to landscape. I'd thought you were able to record the same framing with your phone in either portrait vs landscape as a feature of the app, but I could be misremembering something whilst also completely misunderstanding the hardware limitations of such a feature.

Cinema P3 has developed into a beautiful App - especially h265 422 2020 HLG at 25MB/sec delivers qualities comparable to ProRES 422 (otherwise same settings) at far less stress on storage.

Cost is a much higher power use. Even if the App has been pushed into the background.

If you carry a tiny powerbank (I use on of the “multinames” 8 mm thick) at nominally 5000 mAh (stupid spec, but…) or around 15+ Wh you’ll be safe for most anything during a day of travel.

I’ve just completed a two week stint in South Korea, and in conparison to even ProRES 422HQ (did some comparisons over the days - comparing in the evenings) on Apple App, results were very similar. Except for storage use. Day or deep night. Indoor or city scapes - whatever.

If you need ProRES Blackmagic will work fine.

I can confirm such results.
The only disadvantage of HEVC: you can't switch off all the 'enhancements' Apple is applying to video.

The same thing for me, since the update to v2.0 on iphone 15 pro max (ios 18). As soon as i click record the image on the screen turns to LOG. Doesn’t matter if Record LUT to clip is checked, the image still shows in log profile and so is the recording. Worked fine prior to the update.

Very happy to see the new update 2.1 introduce several bitrates for HEVC encoding.

I AM scratching my head a bit regarding the spectrum of chosen bitrates... We have 4 levels:

Max, High, Medium, and Low

and they range from 54Mbps to 18Mbps which seems like a very narrow spread. I'm assuming the numbers in the names are the max/average bitrates and not the minimum bitrate as I suggested in a previous post (which I admit would be confusing).

Surely, a setting called 'Max' (quality) suggests that I will not see a SINGLE macro-blocking artifact, regardless of how complex the scene is!?

Something tells me that 54Mbps won't cut it. Is there a limitation within the API that I don't know about? Would anyone from BMD like to enlighten us on the thought process?

I haven't done any tests yet, so there's that. Of course, I very much appreciate the update!

Blackmagic is still a bit timid on the h265 front. There are better alternatives.

The App Cinema P3 Pro (Pro version was a onetime payment), that allows a very flexible approach - akin to the options for ProRES. I mostly used 25fps h265 25 MByte/sec (yes 200 megabit/sec) 4k 422 2020 HLG (Log also a possibility) during a recent trip to South Korea in September.

There is practically no visible difference to the same settings used in the far more "storage intensive" ProRES 422, and on Apple Silicon, there is no problem editing in either FCPX or Resolve Studio for my purpose.

Competition is not always a bad thing for users :lol:

Kurt beats me to it ;-)
Well, Sony is using 200 mbps for UHD in HEV 10 bit. In Cinema P3 I can set the bitrate for HEVC to 25 MB/s, and that's a capital "B", so about 200 mbps too, as he already wrote. I made tests with very critical shots, like a tropical rainfall onto a lake with the sun on the other side – no visible block artefacts. So, it's not limited by the API.

Guys—not interested in any posts about other apps in the Blackmagic Camera App thread.

This thread is Blackmagic Camera App-specific.

It's great that you are suggesting apps to users that you find useful. But let's keep any further mention of OTHER apps contained in other threads. Perhaps break out some of the posts here, or just start a new thread (if it doesn't exist). Also, a well-titled thread makes it even easier to find the information for those interested.

Thanks for understanding!

I didn't mean to imply that h.265 HEVC itself won't support higher bitrates—there are many examples of that—including exports from Resolve.

Still interested in hearing the reasoning behind the current 4 flavors being so similar in size, though

These "other apps" comparisons are useful in tracking down anomalies.

For instance, BM Camera now refuses to record using my BT hearing aids. This worked previously and is quite valuable, at least to me. It means that I have a continuously available wireless microphone.

Cinema P3 happily detects and utilizes them. This indicates that the problem is not Apple or Bluetooth related, it's a BMD issue. Absent the CP3 info, I'd have no idea where the problem is.

For another example, BMC displays a LUT corrected image in the viewfinder unless you're recording with IS invoked, in which case the LUT drops out when recording starts, leaving the operator with a severely disabled view. This problem doesn't exist in the native Apple video app. Again, this helps us track down the source of problems.

There seems to be a bug introduced in version 2.1.000170 which wasn’t in the previous version. When recording using the H.264 & H.265 codecs and adding a burned in LUT the color space tag is being saved incorrectly as REC.2020 even though I have selected REC.709. It works correctly when you record in ProRes though. All the clips I recorded on the latest version of the app are now displayed in REC.2020 rather than REC.709 on my iPhone 15 Pro Max. This makes them appear overly saturated and with too much contrast. Anyone else having the same problem?

version 2.1 : using the “standard” stability mode induces weird image glitching at the “120mm” lens mode. Switching to “cinematic” stability looks ok. Using an iphone16pro.

Have you tried using MediaInfo to get the actual formats and specifications of the file content?

The footage from "mobyclick.de" looks normal to me, and the YTouTube link you provided also did a clean play as seen here with 2160p playback format).

I think the problem is the "Increase Sharpening", which probably is not a good idea when you have a backdrop like this with all the itsy bitsy stones and waving branches.

What playback format do you actually get in YouTube?

The source is 4k but watching it in 1080 on youtube it does not look that horrible, but I guess that is because yt reencoded and lowered the bitrate.

Any further feedback, if it is really "oversharpening" or any other ideas, is highly appreciated :)

Looks like Apple's typical 'enhancement', decided by some marketing folks asking the average Joe.
You need to use log to avoid that.

Have you tried using MediaInfo to get the actual formats and specifications of the file content?

The footage from "mobyclick.de" looks normal to me, and the YTouTube link you provided also did a clean play as seen here with 2160p playback format).

OK. I'm "never" commenting on the "artistic content" of recordings. I assumed, lacking any direction other than "if the video should look like this", and seeing this in your post:

Skærmbillede 2024-10-30 kl. 05.48.43.jpg (258.91 KiB) Viewed 31815 times


I thought, that you were commenting on the two, black bands (top and bottom) in the YouTube play window.

Whether you, Google or YouTube has "oversharpened" anything is not to be judged by mere mortals, like me. In general, YouTube is the perfect platform, if you want to be sure, that anyone anywhere on any communication line at any speed can receive "something". That's the big benefit of YouTube. But the downside is, that there probably is no chance, that anyone anywhere will catch a glimpse of the original material you fed into YouTube, making quality judgements on "artistic decisions" (or not) a bit saucy :D

Hmmm... You should contemplate quoting the post, you answer, else it's hard to decide, what post you answer.

If you comment on the "Alexander Hau" post, I fail to see, where Apple comes into the picture for the original material, if MediaInfo is correct:

Code: Select all

com_apple_quicktime_software             : Blackmagic Cam 1.4.0042
com_apple_quicktime_model                : Google  Pixel 8 Pro 24mm


I fail to see, how "Apple's typical 'enhancement', decided by some marketing folks" affect the result from Blackmagic App, presumably installed on Android firmware powering a "Google Pixel 8" enter the picture. ;)

But, as I said, I'm not absolutely sure, what post you refer to, so correct me, if I'm wrong.

Regards and a big smile

I am sorry. I thought the problem was THAT obvious that I did not explain in detail what bothers me with the image quality. It is the noise and artifacts throughout the image.

@Uli
You need to use log to avoid that.

Unfortunately the Android version does not have that option yet.

I see if I can create some controlled environment and to a comparison with the "Increase Sharpening" switch on/off.

If that phone doesn't offer any possibility to reduce sharpening, you're out of luck. I don't think YT is doing that (even if they may do bad things to our footage).

@Kurt
I forgot to add the smiley, but I wrote "looks like…". They all try to compete with that illusionary sharpness, which is even more ridiculous if one offers UHD.

You seem a bit obsessed with Apple’s approach (even when they give you the option to opt out).

As far as I can remember (since digital saw daylight) all manufacturers have added their “spice” to jpg (and later videos) in one form or other - certainly involving sharpening too in addition to heightened contrast and saturation - whether, we”re talking Minolta, Canon, Olympus, Sony, Panasonic and a host of other brands now gone and mostly forgotten.

I see nothing wrong with manufacturers striving to deliver “looks” out of camera, that users seem to want, many even demanding.

We can avoid that, by using RAW, log etc., but the funny thing is, that many people simply do not find the hazzle involved worth the outcome.

In the”good old film days”, things were far worse in many respects, especially sharpness, when going back to my days before autofocus - even when reportage was not involved.

On - for example - the iPhone, I can decide to use HDR instead of Log, and be pretty sure to nearly always have a “usable” result in adverse conditions and light. The outcome is heavily manipulated and “rebalanced” plus “denoised”. So be it, if that’s what it takes to get the results. Choosing log instead in some adverse situations - once in a lifetime travel at night comes to mind - only virtually guarantees a plethora of non-recoverable results.

So, I’m not a true believer in log in all conditions.

Have tried extensively. Today it only becomes a question of “knowing your tools” and their benefits and limitations in situations, I can NOT control.

Don’t get me started on “old farts” simply loving color space rec.709. I’m an “old fart” simply loving the option to use even “subset” Rec.2020 as a base requirement. Just as the fairly recent Lightroom Classic option to work in extended colorspace has brought new life into tens of thousand old RAW images taken the last twenty or more years. Not false colors, but the option to use information actually stored in RAW. I’m also a sucker for using ProRES RAW in controlled environments (only).

My target media is modern and potent screens, not paper or “old TV”.

That’s my preference. You may differ loudly. Won’t alter a thing. I still listen, test etc. but will continue to make my own decisions for my use cases.

In essence, it’s a case of taste. I, you and others may not share the same preferences and taste, but if you absolutely want to repeatedly complain “loudly”, at least attribute the correct manufacturer (in essence, I don’t really believe, that you forgot the smiley ;-)

Regards and LOL!

P.S. Sorry for the many words, but you hit a nerve as dear to me, as log is to you.

All good, Kurt ;-)
I'm one of the old farts who turned down sharpening (or whatever they called it) in any camera I got my hands on from the days of post-production – if there was post involved at all. Of course, if you need to deliver live or a tape right to the hands of a client, one needs to add spice to taste and leave it like that. I just like to keep control, if possible, since you can add salt all the time, but can't take it out. Some folks were shocked when I went to -7 and thought it's a kind of blur filter!
Don't even get me started about TVs adding their additional sharpening, turning those edges into more than one…
Red made the first camera ever for a broader market not to add any sharpening – with the result that all people who were used to that effect started complaining that it can't have 4.5K resolution. (Which it actually doesn't have, but due to the interpolation needed for every Bayer sensor.)
What Alexander seems to object to is too much sharpening, that's all. Unfortunately, it seems in his phone you can't tune it down.

On the iPhone 16 pro, the software is skipping frames/jumping while filming in telephoto (120mm) especially when recording in LOG/60fps. (I know this is demanding, but I've also had it skip when shooting 24fps)

Also, I've had the audio source switch from built in microphone to none multiple times without me changing it in the settings. I'm not sure if the default is none, and then when I use my iPod pro ear buds with my phone that it recognizes them as a source, and then defaults to none when I disconnect them (just a theory), but for whatever reason, it has shifted to none on its own multiple times and then when I went to record I accidentally had audio off for the first few clips. Just thought you would want to know. Thank you. Aside from these hiccups, I truly love your cameras and software!

I saw the high contrast oversaturated look a couple of times during my early experiments with my 16 Pro Max. I didn't associated it with an incorrect colour space. I'll investigate. Thanks!

The switch to none for no obvious reason has happened before on iPhone 15 Pro in the early days of the App. Even in cases, where no external devices were involved. In one case HLG, 25 fps 4k, involving several hour long series of takes of various length and later discovering, that one take had no sound. Can’t remember the details anymore - happened back in february this year.

Reporting the issue lead to a lot of bruhaha (not from BlackMagic, but a person vehemently denied the existence of the problem).

I don’t have an iPhone 16, but on the iPhone 15 Pro - in my case - it was periodic and infrequent with no obvious cause (as far as I remember).

I recently upgraded to iPhone 16 Pro Max with iOS 18.1 and am using BMCA 2.1.000170. I discovered almost immediately that I cannot turn off the Camera>Use Volume Button To Trigger Record selector. It is turned on and grayed out so that it cannot be toggled off. I cannot find the similar feature in the new iOS settings now either. I need to turn this off. How do I do that?

TIA

I’m in the mood to try a few new Apps (and revisit old Apps, I haven’t really tried the last year or so).

I have a problem with the poor quality of the video from the Blackmagic Camera on the Google Pixel 8 Pro phone. I see that the poor quality is not only with me.
Mainly very poor picture quality, lack of detail and presence of many artifacts, strong chromatic aberration. This is strongly expressed in areas with high contrast.
The other problem is the poor optical stabilization with a strongly pronounced wobble effect.
I attach two raw videos, one from the Blackmagic Camera, and the other from the stock camera of the Google Pixel 8 Pro. Also a combined video with both together, reduced to 1080p and the only corrections are CST from BT2020 HLG10 to Rec. 709.

Re: Blackmagic Camera App - Issues/Bugs

Mainly very poor picture quality, lack of detail and presence of many artifacts, strong chromatic aberration. This is strongly expressed in areas with high contrast.
The other problem is the poor optical stabilization with a strongly pronounced wobble effect.
I attach two raw videos, one from the Blackmagic Camera, and the other from the stock camera of the Google Pixel 8 Pro. Also a combined video with both together, reduced to 1080p and the only corrections are CST from BT2020 HLG10 to Rec. 709.

Please put the images on a shared drive and a link with a space in the path.

I can share the videos, but the forum does not allow me to put a URL

Asen, do you have 'reduce noise' and 'Increase Sharpening' turned on in the Blackmagic Camera app?

Also, have you compared other cam apps and not just the default cam?

Only reduce noise is ON.
I have compared it with mcpro24fps and the demo version of MotionCam, but the problem with them is different. With the first one, it is with the stabilization and that the video looks shot in low key, and with the second one, there is a lot of noise in the shadows. I think the stock camera is the benchmark for comparison.
