Develop Bugs

Is [email protected] due to the software?

As Google announced at their event, the GN should film [email protected], but after seeing the many review which are available on the net, the conclusion is that the GN only films at 24fps.
Could this be fixed through software? It would be a huge lie, if Google mentioned 30fps, reality being something else.

i would also like to know that.. really dont like 24 fps

Is that why the videos seem so choppy ?

generally, most film is done at 24FPS which is the standard for NTSC. in the past, they would 'convert' films to 30FPS by "splitting" the A/B fields in the video in an attempt to give it a more fluid sort of feel. they originally did this for older tv sets though...
if you were watching such films on a newer TV for instance you could tell a video's been converted by seeing occasional weird doubling/lines appear in motion-filled areas. tv's/pc's though have software "filters" to hide this effect, at least the lines part.. but if you have good eyes you'll still see the occasional doubling(ghosting).
considering the compact size of the GN screen though, you should not see "jerkiness(choppiness)" unless it's some sort of hardware or software related issue.
[EDIT] although it would still be weird to do a full 1080P video and limit it to 24FPS even if you are just watching it on your phone. the whole 24FPS thing was from the DVD days.

This is normal spec of 1080p videos. If you had an HTPC you'd probably already be aware of this, as some videocard manufactures have a bug were it's not fully 24fps, or alternates causing you to see a shudder..

When filming at 1080p it is usually done at 30fps...

The FPS is usually capped in media_profiles.xml that you can find in the source on AOSP. That's where the quality settings and codecs used per setting is defined.

But why all the video looks like under-water

Film is 23.976 fps. If your video card is set to 24fps instead of 23.976, you'll get a stutter every 41.66 seconds.

[Q] What is a good mp4 editor (GN4 and PC)?

I'm looking for a decent video editor for when I take video with my phone. Let me say, that I'm honestly a noob at this. I basically want to be able to trim a video (beginning and end), and if necessary, flip the videos. That, and also eradicate the problem I had with a video I took yesterday. It was basically a concert at a bar, where I was right in front, inches from the monitor. The sound was great. The singer's hair was blonde, and his hair basically reflected all the, I guess you call them skyhook lights in the ceiling, so there was an annoying glow around his hair. The drummer of the band had a glass shield around him, probably for noise cancellation, and in the video, I could see the glass light up from the lights as well, in a similar fashion to the singer's blonde hair.
In short, 3 questions:
App to trim videos.
How to flip videos (they looked 90 degrees off on my phone but perfect on my PC)
How to eradicate glow from light shining on blonde hair and a glass shield.

Move Request
Can a moderator please move this to the Q & A section? Sorry, I missed the initial sticky post. Thanks.

Did you hear about Faasoft MP4 Editor? My friend recommended it to me and happy with it.
It seems to do the tasks for you.

Anyone use the Z5 Premium as a VR entertainment device?

So I read through the other thread that talked about VR, but it's dead. So I'm posting a new one to see who's currently doing this, if anyone at all.
Are any of you using the Z5 Premium to watch movies through VR? I've never ventured into VR territory but the Z5P keeps luring me in. I don't care about gaming, and I don't care about 3D. What I'm really looking for is a way to block out the rest of the world and watch a movie. It can even just be pitch black around the movie (I guess that's called Void cinema in the world of Oculus?).
There's got to be one of you out there.

I used it twice with a plastic, adjustable and good quality cardboard a coworker bought and it was very cool, as the screen is ver big, it filled the space of the cardboard. I tested some games but for movies I guess it would be cool to. In fact, Im planning to buy one soon. I recommend it

I've post my experience with watching 3D movies using VRTube on another post + pics perhaps you've seen it. Also, Sony's image enhancements works with VRTube which is great, too bad Sony sound effects do not, i suggest using viper4android for sound enhancements. Also VRTube is pitch black around the screen so it'll be perfect for you. I use sony's bluetooth headphones for a complete wireless experience. I can tell you that the picture is superb, no screen door effect from pixels. I use the colorcross headset since that works best for movies imo. I haven't found a headset with a clearer lens than colorcross although i stop buying headsets a year ago since I've wasted so much money on them, (trial and error).
I've been watching 3D movies on mobile for about 2 years now using this setup, the previous phone i had was the LG G3 (2k screen) which wasn't bad but still has the screen door effect. After upgrading to xz5p my vr experience got better so yes i'd say it was worth it.
I forgot to mention i use a bluetooth remote with a mouse cursor mode, you can get one for cheap on Amazon unless you want to keep taking out your phone to make adjustments.

Have you used the Bobovr Z4? I've read that a lot of people like that unit. The VRTube app you're speaking of is the one by IdeaMatters (https://play.google.com/store/apps/details?id=com.ideamats.vrtubefull)? The one that looks like it still has Gingerbread interface?
You can get through an entire move no problem without it overheating or anything like that? What do you look for resolution-wise when you're sourcing your movies to watch? Sorry for so many questions, I'm completely clueless when it comes to VR.

Yea that's the one. The phone gets warm no overheating, I lose about 20%/h watching movies, All the movies i have are all BlueRay quality in its highest resolution, The movie file can take up 10-20gb each..

That doesn't say much. So I'm guessing you're sourcing BluRay 4K rips at 3840x2160, ya? So I'm just trying to educate myself, but that would mean when you watch it in your VR headset you're effectively getting 1920x1080 to each eye and watching the film in FHD?

No the full video resolution is usually 1920x1080p so each eye would be getting 960 x 1080

But I'm guessing that's still plenty clear and enjoyable due to the lack of SDE?

Yup.

So I just got my Z5P yesterday, but first time playing with it tonight. Do I need to force 4k through ADB or anything like that to get the best VR experience?

No. Android automatically plays back video (anything using SurfaceView which is just a buffered view) at full resolution.

If that's the case, than what's going on here (2k vs 4k resolution)? Am I able to make the VR screen larger but in essence the video played within it is the same resolution for both?

Then it'll better be 4k Blu-ray video with 20 more gigabytes
And the device will get slower during the time (it says cannot play video) you need to restart

Youtube Full screen (pinch to zoom) screen got Cut to much

Just got the Galaxy A50, and learned about the Pinch-Zoom to fill the screen(remove black bars) but the videos get cut too much IMO, is there a way to fill it without cutting too much?

No way. Depends on the youtuber in which aspect ratio he films the video.

General Initial Video results - Needs tweaking

Note this isn't a bash the pixel 6 or google post. It's just my initial impressions with only a couple of shortish video samples.
I took the P6P out yesterday and put it in a mount next to a GP9. I went out to the trail and recorded sections of footage with runs and walk sections.
It was full sun for the most part, no clouds to speak of, at 1:00 p.m. (ish).
The results were... lets say interesting. I can't share the footage unfortunately, it was BF and gorgeous weather here so no one was working or in school and there were families all over the place and I don't post videos with minors in them. I'll have to go back out on Monday during the day when there won't be any one around.
Pixel 6 Pro settings - 4k/30 Active mode stabilization, exposure and color set to auto adjust (defaults)
GoPro 9 - 4k/30, flat color profile, white balance 5000, ISO 100/1600, Sharpness Low, Shutter speed Auto, bitrate High (100mbps), EV -0.5, Hypersmooth Boost+Horizon Lock.
Both were left to record out to HEVC format.
The GP9 settings are my default trail running settings. For me 1gb of space was used on the P6P in roughly 7:30 so to make for easy comparisons I checked the same 7.5 minutes storage burn rate on the GP9.
7.5 minutes of 4k30 on the P6P consumed 1.07gb of space.
7.5 minutes of 4K30 on the GP9 consumed 5.50gb of space.
That puts the P6P with an effective about 20mbps bitrate, at least for this one sample.
Pulling the footage into DaVinci the Pixel footage and putting them side by side, initial impressions -
P6P was obviously sharper since the AI is doing that on the fly. I'd like to see an option to turn this off as I prefer to handle it myself in post but I find it acceptable. Adding 0.44 sharpness in DaVinci to the GP9 brought the two by eye pretty close.
The color space between the two was visibly reasonably close to each other which I liked. In at least this footage there's room to color grade the P6P footage, it's not blown out or over saturated like I get with the GP's native color profile. I could probably use the same grading on both footages with only minor tweaks to merge them somewhat transparently in the same comp.
I noticed a bit of exposure and color wobble at times on the P6P footage. I think auto exposure and color needs to be turned off on the P6P if you're at all going to do any color grading or post work on the footage.
The lens flares on the P6P were noticeably worse than the GP9.
A major complaint I have right now is the P6P footage seems like it would just randomly pick something to focus on and shift the video off to the side. There are a couple of spots it was like I had the two devices on different mounts and was pointing the P6P off to the side of the trail. It was bad enough at first I thought, "did the phone mount loosen up on me and I didn't notice it?" But then it would correct itself and 'aim forward' again.
There were also what I can only assume are frame drops or weird focus choices as there are a few places that look like jump cuts were done on the P6P footage or the AI jumped around the sensor to focus on something else.
There's also signs of the jello'ing in the P6P from time to time.
Overall, without updates/tweaks or opening up some values for user control, I don't think the P6P is going to become my primary recording device on ultra runs unfortunately. Which is a shame as that's why I bought the 512.
For less motion heavy recording like walking/running on technical trail this may not be an issue.
I'll have to see if there are alternate camera apps or putting the P6P on a gimbal and turning stabilization on the phone off. If DJI would ever get the OM5 working 100% with newer androids (P4 is the last official supported Pixel) then that might make for a solid combination. Or wait for updates.
And there's also the incredibly annoying issue of "No you can't turn off the screen while recording because perverts." problem with mobile devices which also adds to the power burn problem. There needs to be some quick way to drop the screen brightness down to 0 while recording IMO.
Other points, 4K/30 video burns through the power as well, more than I like. I started around 68%, finished with 34% but to be fair while I only recorded about 12-15 minutes total footage, I took a crap ton of pictures out on the trails so I don't have a solid idea yet of exactly how bad the burn is going to be. Nor what the impact of setting the display to it's lowest possible brightness will do to help with that.
Also to be fair my Garmin live track was running for the entire 3 hours of the run and there was crappy cell service in that area. But that's the normal for what I wanted to use it for.
Once I have footage I'm okay with posting publicly I'll throw up a side by side view in case someone finds it interesting or helpful.

I don't usually take video, but on a couple of occasions I tried to, it was unusable. Granted, I tried to zoom in at 4x on both tries, and the results were so pixelated and overprocessed, that the footage was unwatchable on anything larger than a phone.

Thats because Google stupidly don't use the 4x telephoto on video. It's a crop.

That's where your wrong
It uses the telephoto but only if your using 4K30fps
@Ultimoose the P6P uses 43mbs for 4k30 and 62/63mbs for 4K60
Already tested it before and checked mediainfo for bitrates

Quick question from a noobie: why not using 4k/60fps but only 4k/30fps?

I think comparing GoPro 9 video results to a smartphone video results is setting the P6P up for failure.
The GoProv9 (I have the Hero * Black) is solely built to be an active sport recoding device, nothing else.
The P6P is a smartphone that offers the ability to capture video, which I'm pretty sure wasn't designed around mountain biking, trail running, or active outdoor sporting.
Even if the comparison was sitting at a table filled with friends using these two devices; one is specifically designed to capture video, and one has a video capturing feature.

the 4X telephoto zoom works only with 4K30 but it works very wel
though honestly could be a software limitation
Some nice zoom today in the cold (looks better in 4k once processing finishes)

I'm a pretty aggressive mountain biker and the GoPro hero 8 black is amazing at video stabilization.
Biggest issue with the GoPro imho is the inaccurate depth perception. Not sure if you meant video horse shows while on a horse or on a static mount.

I was sitting in chair watching. No mount. Auto focus and the horse's motion were glitchy. Still learning those video settings. I had people's heads in front of me and horses in background. The focus on people's heads were perfect. Lol. Maybe turn off auto focus and do manual?

I tried them all. Experimenting. I shot a bunch of stuff. Have to go through it and see what is what.

Found the issue with only seeing 20mbps bit rate. With Active mode stabilization you lose the ability to shoot in 4k/30, it drops to 1080P/30 (technically 28.7 and 28.6 in two different clips so it's not quite the normal). This is a personally painful limitation for me.
So if you want active motion video you either settle for 1080P, less stabilization or use a gimbal as of right now. Except DJI doesn't fully support the P6P / Android 12. Just mostly works.
Side note, the DJI Fly app doesn't work at all on the P6 (or android 12 to be fair). DJI's current official recommendation is to find a phone that their app works on.
The joys of early adopter.

Depends on the recording device. On a GoPro 4k/60 and 4k/30 both use 100mbps (with high bitrate selected) to record the video/audio. In order to fit 60 frames per second into the same storage space as 30frames per second the GP uses higher compression which results in lower amount of data per frame. i.e. 4k/60 is lower visual quality than 4k/30. And 4k/24 would be slightly higher quality than 4k/30 but the Pixel doesn't record in 24.
I only use 4k/60 for clips I specifically intend to slow down in post personally.

I captured some more footage and rendering it out now. I'm going to have to say the Pixel 6 suffers in comparison at 1080/30 with Active stabilization. To anything that records video in some respects, not just against a GoPro.
For example: There are frequent freezes where the Pixel's video records the same frame over several frames, I've counted as high as 10 frames of a static image being recorded. This results in what looks like a jump cut transition when it catches back up. This happened several times in the first few minutes of the recording and the outside temp was around 45F which should rule out an overheating issue. Notably the phone recorded the entire 32 ish minute run without shutting down.
The focal point (not focus) drifts pretty badly as well at times. There are spots where it literally looks like the pixel is aimed off the side of the trail while the GP is aimed straight forward with both on the same mount. The camera appears to be shifting which portion of the sensor it's recording from not in a good way. I'm familiar with active stabilization artifacting from this kind of movement, I've owned or own every GP except the 1 so I've seen how EIS has grown and matured over time but the P6's drift and yo yo'ing is not pretty at times.
The jello effect is also noticeable as is the exposure shift although not OMG this sucks kind of way, it's more a ugh, that's ugly kind of way.
The above may be issues with the Active mode stabilization. I wasn't expecting it to be this janky or I'd of recorded other segments with EIS set to 'light' and 'cinematic'. The 'locked' mode which I assume means no stabilization would only be of any use mounted to a stationary tripod or possibly a gimbal.
Once the render finishes, uploads and the full resolution is available I'll post a link. It'll be a few hours at best as YT takes forever to provide the 4k format for me.

Side note, the Active stabilization when it's working seems solid, I'll need to see the rendered side by side but in my editor it's making a solid showing going up against the GP9's Linear+HL+Boost combo.

Nice...very curious to see your results. And thanks for explaining all this!
