[Q] How do you export the slow motion video?

I've captured some slow motion video on the G3, but when I try to export it anywhere, or play it in another player it just speeds up to normal speed.
Surely this can't be right. It should save the video to be played exactly how you see it in the native player on any other device.
Does anybody know how to get it to stay as slow motion even after you've exported it, or save it as seen in slow motion?

To let you know I have done a search for this issue within xda, and it doesn't show any related threads. Has nobody experienced this issue?

Hi,
Your Video is fine. Just use a Player like VLC and reduce the playback speed.
Thats how slomo works!

Thanks, I thought it would be better if it actually slowed the footage down as a saved file (like on the Xperia Z2), then at least you could post it to a shared website and show off your creation. Is there no way to do that?

Check the PlayStore - there must be an app for that Good Luck! If you find something, share it!

The HTC One (M8), Sony Z2 and iPhones have a video editor that can slow down parts of a slow motion video, while keeping the rest of it at normal speed.
Has anybody found a similar app on the Play Store?
Or even, has anybody managed to make the Sony or HTC app work on other devices like the G3?
EDIT: The Sony Z2 app is called "Timeshift Video".

Im looking for this too.
Its crazy - shows slowmo video in gallery app - but with normal speed in Photos app

What are you guys taking slow motion video of anyway bouncy boobs lol

It doesn't matter what you take a slomo video of, the point is that the phone doesn't let you save the movie in a way that can be played in other devices. Surely it should do that.

I've seen a few slomo videos on YouTube made on the LG G3, how have they done that, if you can't actually save the video as the slowmotion version?
Surely, you'd want to show off various or interesting slomo videos to friends and family, so there must be a way to do it. I've looked for an app, but surely it should be native on the phone?
e.g. on my old HTC EVO 3D, the 3d videos were stored as 3D to see on a 3D TV for example if saved on a USB. Surely if you save the SloMo video to a USB you should be able to see the video in its slow version on a TV. Is this something that LG overlooked, or is there something that we're all missing on the phone?

The recorded video file is ~120 fps:
Frame rate mode : Variable
Frame rate : 119.659 fps
Minimum frame rate : 116.732 fps
Maximum frame rate : 122.783 fps
To see it in slow motion you would have to set it as 30 fps on a computer and save it again. No need to recompress it or anything (so no quality drop at all) but you need this extra step to play it back on a device where you cannot manually slow it down.

Thanks for that info, I wish thought that the phone natively did that, so there was no need for that extra step, I think LG are missing a trick there.

@Bad4ss
Hi, any news how to keep slow motoion afer rec?
when i copy to my pc or uploading it it get normal speed...
can I chose slower speed even if i rec on normal speed ?
any pic?

The most simple way I know is to use mkvtoolnix (free, open source and works on windows/linux/mac)
Open the GUI, drag or add the file you want to work on, select the video track, go to format specific options and select your desired fps. Then press "start muxing".

Thanks; upgraded from 6.2 to 7.1 and mixed away. Video worked well but audio didn't seem to work out well

When I shot something in slomo on my Galaxy S4 the resulting video was slomo in all viewing apps or when uploade to facebook or youtube. only being able to view it in slomo in the LG gallery app is dumb. As much as they advertise the G3 as a great photo device the camera app actually sucks balls. Samsungs camera app is light years better and IOSs blows them both out. It still baffles me that android has no tap exposure and lock capability....

Is there an app that will save the lg g3 recorded slow mo videos and directly share them so everyone can see the videos in slow mo?

When uploading videos in youtube you get an option to increase or decrease default video playback speed.

I use an app called Lapse it Pro to import the file then render and save it at 20fps. After rendering..I'm able to share it as a video file

1080p 60fps recording

Hi. Does anybody know why HTC doesn´t support 1080p 60 fps video recording? Is it software or hardware related? If it´s software related, is there any possibility to record video in 1080p @ 60fps?

Hardware is definitely capable. Lots of apps in play store will record at 1080/60fps. I haven't tried any, I'll leave that to you.

Hey, I am also interested in this topic. In fact the only thing holding me back getting a 10 is the question if it is able to record 60hz at least with an after market app. So could anybody who already owns one try this please?

Open Camera doesn't work
Tested Open Camera from the play store. You can set the framerate to 60 fps but it will still record in 29.97 fps.

Is X265 10bit 1080p mkv supported?

Is honor 8 pro capable of playing X265 10bit 1080p hevc video?
I've tried samples from jelly fish with stock player, mx player n vlc. None works. Tested the same on friend's op3t phone n it played smoothly with stock player. Even X265 10bit 120mbps 4k video was played without lag on op3t. But this honor 8 pro cant even play 5mbps X265 10bit video?
So is this hardware issue on honor 8 pro?
Any suggestions??

Yes. It's absolutely capable. I just tried. Make sure you're using the latest vlc 3.0.0

Try turning the hardware acceleration to Full in Vlc.
Are you on EMUI8?

Hardware acceleration is to full and m still on emui 5.1, waiting for ota update.

If its of any help, attached is the screen grab from stock player.
Playback is smooth but with distorted colors.

I too had this problem on EMUI 5.1
Wait for the update. It may solve the problem because I didn't encounter this problem on EMUI 8.

Thanks for your help!! Will update once i get oreo update..

So my phone has been updated to emui 8.0 and phone has been factory reset post update but this issue of non playing X265 10bit videos is still there.
Any advise?

1080p hevc mkv videos cannot be played with inbuilt player (due to colour distortion, though videos are played). With MX player, HW decoder is not supported; video automatically starts playing with SW decoder. With VLC full Hardware decoding is supported without color distortion (but still playback is not that smooth, sometimes even videos got stuck).
Overall video playback on honor 8 pro is poor. So don't expect much.

The chipset is surely capable but I don't know why this happens.
Vlc does play the video but if the video is skipped, it gets stuck on that frame.
Maybe because the kirin chipset isn't widely used and thus, there are optimisation issues with many apps. I get dropped frame rates almost in all games and this baffles me because the chipset is fairly powerful.
I am not buying device with kirin chipset again. Lots of optimization issues with 3rd party apps.

it would be really sad. u've contributed a lot to this community. to say this means we won't see you in the honor/ huawei section that often since they usually stick to their own processor.
but yes, it does seem sad that there's really not much optimisation... though for the GPU, it is still MALI, which is also on Exynos.
i can only hope things will be better and Huawei/ honor can really work with more developers.

I can't really say if that first line was sarcasm or not.
This device can't play any game without skipping frame rates. It lags pathetically on playing temple run 2.
There are clearly optimisation issues for 3rd party apps because they have optimised it exceptionally well for their own apps and the whole software. This ruins the overall experience because as the OP stated that a device with SD821 plays 1080p 10 bit x265 videos smoothly while this doesn't.
Exynos devices may not be relying from this same problem because Samsung sells those devices in a lot more number than Kirin devices.

why do you think it's sarcasm??
as for Exynos devices... they also use MALI GPU, though it's a diff variant of the chip. still, if they can get it optimised... i guess we can hope it's the same for Huawei/ honor. after all, Huawei/ honor is also one of the top manufacturers in the world right now.

I felt it was sarcasm because I don't think I have done anything major for the community here. I am not a dev [emoji12]
I haven't used an Exynos device. So, I am just guessing. Yup, I know they both use the same GPU but with lesser number of cores though. Maybe that's the root cause of this or it's just pure optimisation problems, don't know because reviews didn't show any such issues with this device. I am really confused.

Yes even i am also confused as reviews shows no such issues but it can be possible that not many ppl really tested these specific vidoes on this device. Hence I posted screen recordings of my phone. Need some more testers to see if I m the unlucky one.

Stock player plays video smoothly but with lot of color distortion. VLC just hangs after 1sec and MX player plays through SW decoder with lot of stuttering. XPlayer from Google play plays video much better but still stutter a lot. Overall you can't play x265 10bit HEVC videos with higher bitrate n framerate and of higher file size on our H8Pro. What a disappointment. I tested the Jellyfish sample video which was around ~33mb and main10

Not only in hevc, x264 video playback also have a bug. The 'blacks' are not shown properly in HW decoding of MX player or inbuilt player or VLCs full Hardware decoding or any app using internal codecs including video playback in YouTube app. There is a permanent 'tint' over video (only video screen) when played in these ways. The tint is absent in SW decoding mode of MX player which means the fault is in internal decoding.
To check this pause a black scene of widescreen video (so that there are top and bottom black bars). The black bars are distinctly visible in inbuilt player (and other playbacks that use internal decoding); But screen is full black (black of screen becomes same as that of bars and so can not be distinguished) when SW decoding of MX player or VLC (No harware acceleration) is used.
Not only blacks become greenish black but all colors become slightly dull compared to actual.
This most probably wasn't before oreo update.
Also there is one more magic to it. I tried to attach screenshot, but the screenshots are clear (tint is absent), even when screen recording is on tint dissapears and reappears as soon as screen recording is turned off.
I had to take shot from another phones camera. Pics in attachment is of same black scene (video paused). Screenshot is completely black while photograph shows how it actually appears (distinct top and bottom stripes).
Eye comfort or display color settings has nothing to do with it.
I already reported this issue to honor customer care but I don't think it would do anything.
Anyways, there is NO way to fully enjoy videos in our honor 8 pro. We have to just accept this. To avoid frustrations: stop downloading x265 video, stop comparing with other phones and simply accept what we have.

Redmi note 8 pro 4k hevc 10 bit remux file playback possibility ?

hi i know that this phone support hdr but can it play 10 bit 4k hdr movie ?
has anyone tried it ? i am looking to buy this phone for 4k remux

It works, even the high action scenes where the bitrate jumps up to 50mbps, no stuttering.

Not much to show from a screenshot since neither MX Player nor VLC show real-time stats like the PC version of those apps. I just went to jell.yfish.us and grabbed one of their test bitrate files. I haven't monitored the CPU temps though, not sure how long it'll stay within spec.
Any suggestions on an Android player app that displays all that in real-time?

If you don't mind oversharpening on media content then get this phone.
btw. Does anybody know a fix for that?

Mi box s 4k and on all Xiaomi devices I get video pixelation issue?

Broken H.264 (avc) codec bug!
Problems:
0. Artifacts and ghosting
1. There is a shadow left from the last image onto a black scene that comes after.
2. There is a trailing edge of every lighted scene around the picture.
3. The problem is wide, not only related to single app.
I did notice on Xiaomi devices pixelation on videos.
I have mi box s 4k and chromecast ultra while there is no pixelation for the same video for chromecast ultra I'm getting pixelation issue for mi box s 4k and redmi note 8 pro.
This issue I did notice it for local videos and youtube app (I didn't notice for netflix).
So I did try some methods my self. switching to sw decoding on mx player got pixelation fixed but this isn't precise solution cuz I did read somewhere that hdr is gone for sw decoding and youtube app problem stays.
For Xiaomi devices I did find a video on YouTube. so on mine redmi note 8 pro I did as the video told.
the video did told me to turn on hw overlays so I did turn it on and I got pixelation fixed!!!
youtube .com/watch?v=MGxh2vCmR1E
But for mi box When I turn on disable hw overlays I'm getting no screen I'm only getting audio what could be the cause of this could someone help me to turn this on?
Or is there any other solution how I can fix the pixelation?
Update:
İn mi box s 4k There is no pixelation in apps like netflix!!! but vlc, mx player and chromecast built-in playing local video file is the issue getting pixelation in hw decoder!
imgur. com/a/OO2R8VI
Example:
Hw decoder: imgur. com/US8Xzor
Sw decoder: imgur. com/fUzwKvw
You can see white line in hw decoder.
İn sw decoder the white lines pixelation is fixed.
Update 2:
Someone told me this is a known broken H.264 codec bug! (avc bug, h.264 and x264) I think that person is right! I did encode my video to H.265 and the pixelation was gone!!!
Does someone When did this problem start?
İt is aggravating I hope Xiaomi will fix this problem soon.
