Those that have the Blackmagic app, I'm curious as to the performance and the video quality

I've done some initial 4K testing of the BMD video app on my Samsung S23 Ultra versus the phone's inbuilt video camera.

First thoughts:

• The default lens setting with BMD is wider than with the phone - which is good.
• The BMD's video image is darker than with the S23's camera - not so good IMO.
• Even when set to 25 fps, BMD still records at VFR so the actual frame rate varies and I'd still need to transcode the video to CFR.
• BMD offers a choice of H.265 and H.264 - which is good. I'm not sure if the BMD installation caused this, but H.264 is now an UHD option in the S23 (maybe it was added in a recent update by Samsung but I haven't noticed until now. Note: If H.264 is selected in the S23, the default fps showing in MediaInfo is 29.97 (VFR) rather than 30 fps (VFR) as occurs with H.265
• Stabilisation in BMD is dreadful - Standard is better than Optical, but even so is not even close to the S23's stabilisation. Stabilising in Vegas, Resolve, Merc 5 SAL and Merc 6 SAL doesn't improve the image all that much - what's left is lots of wobbling (jello) corners of the image and, IMO, the video is unusable. I would think that the BMD camera would probably be okay if the phone is locked off and without any camera movement.

At this stage, I'll be sticking firmly with the S23's inbuilt camera. Notwithstanding have to transcode the phone's 30 fps VFR to 25 fps CFR (which I already do in Vegas Pro with Optical Flow activated), the S23's stabilisation is just so much better than is obtainable with the BMD camera app.

@Dexcon Optical flow rendering in Vegas is a pita, takes ages...try (and compare) optical flow in DR.

I recently edited two short holiday movies with VP22, footage taken with the S24 Camera app in 4k30 in H.265. Project went very well in VP22. I had no need to transcode to another framerate because the 4k30 H.265 Voukoder render plays perfect and smoothly on my UHDTV.

short transcode 4k30 to 4k25 test:

DR optical flow renders average about 45fps against Vegaspro renders average 2,2fps. That's 20 times faster...than Vegas...

Thanks @3POINT To my eyes/brain both pans are jerky. PAL 50fps would be so much smoother.

I do not know what YT made out of it, when I play the original rendered files at my PC monitor, only the by Vegas optical transcoded file is jerky...

To me it makes no sense to transcode at all because the original 30fps S24 footage plays perfect at my UHDTV.

Totally agreed that rendering in DR with Optical Flow is so much faster than in VP - and DR has bulk rendering which is really great. When overseas and with only VP on my laptop, I've usually done the phone video transcode 30fps/VFR to 25fps/CFR back in the hotel room/ship stateroom while my wife is preparing herself for the evening. I'm not sure, but I think that DR Studio can be activated on 2 computers at the same time so I'm going to install it on the laptop for next trip that's in about 8 weeks' time.

BTW, phone video represents only about 5% or less of my travelogues so I transcode to 25 fps to match the 95% of video that is sourced from Sony and GoPro cameras all of which is 25fps. BTW, the S23 camera is excellent for still pics.

@Dexcon when its just 5% and when audio is not important then importing the S23 30fps footage at the Vegas project fps (25fps) speed is also an option. You will get a nice slow motion without resample blurring

BTW I use DR free version, no limitations at how many computers.

Yes, except for some situations where a live performance on a cruise ship is being filmed when audio is important. I've found that using a 'large' handicam camera in some circumstances seems to worry some nearby people, but a phone camera is considered much less an invasion of personal space (so many others have their phone cameras up and recording) - people seem to accept phone cameras much more than 'proper' cameras. And this is where the problem lies ... trying to lip sync audio of a performance (personal use only) recorded at 30 fps but then matched to the video transcoded to 25 fps. That issue seems to me - though I could be wrong - to be much less an issue when transcoding to 25 fps rather than allowing the slo-mo approach where lip-sync is easily lost. This is quite apparent when R clicking on the event, selecting Properties, and clicking on 'Confirm to Project Frame Rate' - the video is slowed from 30 fps to 25 fps but adjusting the audio to match the video unfortunately substantially changes the tempo of the audio

@Dexcon Try this method of importing a 30fps video into a 25fps timeline, audio stays in sync (ofcourse audio is also slowdown but in pitch corrected) :

My vacations are more in nature where audio is not that important.

Thank you @3POINT ... even if pitch is retained, I really don't want a performance of ABBA's 'Mama Mia" (and many other songs) slowed down by some 17%. It's like playing a 33 LP rpm record at 27.4 rpm.
