Note 4 (Snapdragon) - Recording at 60FPS with HSR - Xiaomi Redmi Note 4 Questions & Answers

Hi all.
I don't consider this to be a duplicate thread of the previous one I made, because this is a different model phone that I now have.
I previously owned a Mediatek Redmi Note 4X. I now own a Note 4, Snapdragon 625 variant.
I've searched high and low for ways to record 60FPS video. View my previous thread for one solution that was found on a Russian forum.
Now that I have a mido Note 4, I was able to edit media_profiles.xml and try that app out. As explained on the original Russian forum post, 60FPS is unacheivable in places with less lighting, such as rooms. Even my room with what I think has a decent amount of lighting, I reach 40 FPS at most, and sometimes dip to 15 FPS.
However, I found a way to record at constant 60FPS @ 720p, but there is a complication.
If you have the Snapdragon variant of the Note 4, download Snapdragon Camera. No need to flash it, just install this apk:
https://docs.google.com/uc?export=download&id=0By-NOo-lCyxBMTVNNGZyYjdjd2M
Switch to Video mode, and choose 720p in Settings > Video quality. There is also a section in settings that says "Video High FrameRate". This is where you can choose HSR 120. HSR is "High speed recording", as opposed to HFR, which is slow motion. Recording at HSR saves audio, while HFR does not.
I haven't seen anyone else with the following issue, but I have seen only an extremely small amount of people posting that they have used Snapdragon Camera on their Note 4. When you record at HSR, the audio track is retained, but the video ends up ending before the audio does. Your video will also play very quickly.

To sync your video, you can do what I did, and copy the video file to Sony Vegas, then hold control and drag the video file out to match the length of the audio. Render at 60FPS (NOT 120 FPS), and you have your 720p 60FPS video at a constant frame-rate.
Video runs smoothly and properly with synced audio at constant 60FPS after rendered through Vegas, with the video track "extended" to the length of the audio track:
This may help some people who have a computer handy, but this process is rather involved. I was wondering if there is some sort of file that can be edited to change the playback rate of videos taken with Snapdragon Camera so the video will be in sync with the audio.
This is progress, I suppose, since aside from this and the whole MotoCamera + media_profiles.xml method, I have no idea how to record at 60FPS on this phone, and I've literally spent 2 days researching. Open Camera does not record at 60FPS for me even with Camera 2 API (yes, I do have it enabled), and the modded Google Camera mentioned here does not allow me to record at 60FPS giving me the error: "Cannot start video capture. Another app may be using the mic". This error doesn't occur on any option aside from the only 60FPS one, go figure.
Perhaps there is another camcorder that utilizes HSR someone can refer myself and others to? Or an app that would allow you to adjust a video's playback rate so using a computer and video editing program like Vegas won't be necessary?
I know this phone is capable of recording at 720p60. Hell, my old phone was a G3 and it can record at 1080p60 without the need of Camera2 API or any xml tweaks. There's plenty of solutions for recording at 60FPS for the Redmi Note 2 and 3 as well, I find it ironic that it seems to be such an issue on the Note 4.
Please let me know if you can help at all. I hope this also helps guides others who are in the same boat as me.

Same. I've also been wanting to record in 60 FPS with mine since I bought it. Tried changing media profile values, Tried Open Camera. Didn't work. Just now installed the MotoCam port from your old thread, Gives me the weird mic error when 1080p60 is selected and doesn't record.. Mine's the Snapdragon varient as well. But, None of the versions of Snapdragon camera work (Force closes on start). It could be either because I am on MIUI or maybe because I am still on Marshmallow. People have been reporting that the Google Camera port can record in 1080p 60 FPS in some custom nougat roms. But I just haven't made the jump yet to Nougat for the lack of stable Xposed Framework.

Hi, I currently do not own the Note4 device but I think your problem seem quite relating to my concern. My phone (Note3Pro - S650) doesn't provide recording video with high framerate (60-120fps) for 1080p resolution but I found an interesting method from here to do it.
Code:
https://forum.xda-developers.com/redmi-note-3/themes/mod-60-fps-1080p-camera-rn3p-sd-miui-8-t3624366
As you mention, you want to find an App which can handle high framerate video and I myself suggest you to try FiLMiC Pro v6.

There's solution!
Hello guys
I know that thread is quite old but I've found simple solution, how to fix desynchronisation when recording in fastmotion with sound using SnapDragon Camera.
Y'know, during saving there's small error caused by codec and videos cannot be played using videoplayer from Google Photos and with other video players video plays fine but in longer video you can observe desynchronisation between audio and video track.
Check out these steps below :
1. Record video. I prefer HighSpeed 120fps. This gives me in result slomo video with sound (more about that later)
2. Open it using Google Photos. You will see that video not playing well, ignore that and select edit (that icon with bars on the bottom, next to "i" symbol)
3. Select "Stabilize video"
4. Google will process that video frame by frame. 30sec video took about 1min of rendering. Wait
5. In result, Google saves a copy of your original video in your memory which have now sound and video are sychronised. But the best part is that you can set the slooooooomooooo paaaaaarrt and you have audio during that!
6. Now you can keep your new vid and delete old.
Isn't that bylatiful?
I recommend to do that operation immediatly after you have recorded video. Why? Because of date of saving. When are you on vacation, you wanna to keep track of your photos and videos in proper timeline. When you edit your video later it saves with later date and that may be a problem keep your media in proper day.
