Video scrubbing on the S21

Venger · Mar 4, 2021

Hi,

I've been experimenting with frame grabs from high res video and therefore I've been dragging the play head along the play line to find the parts I want to grab. Trouble is, every time I do this, you get the supposedly 'helpful' hint box pop up on the screen to tell you that you can drag upwards to increase the scrub speed...this hint box is on screen for the entire time you're dragging the play head and obscures whatever image is showing on screen, making it nigh on impossible to accurately stop the play head at the most in focus frame you want to capture!!

Anyone know if there's a way to turn the hint box off ?

I do have Vid Trim Pro on the phone and that has a frame grab facility and better still, you can advance the video forwards one frame at a time which makes it much easier, altho if you go past the frame you can't backup quite so easily.

Anyone use or know of a decent frame grab app that actually works and will allow you to nudge playback both forwards and backwards to locate that perfect frame ?

Many thanks for your time.

Check the settings of the app for 'Hints', popups, toast messages, and the like.

Turn this sort of thing off, and hopefully the messages wil go away.

If not, then I guess you would need to use a less 'helpful' app.

Personally, I use YouCut for most all of my video needs.
It allows frame by frame down to the tenth of a second- which although is not super fine, it seems pretty darn good for Android.

@puppykickr just downloaded YouCut and unless I'm being really thick I can't see an option to frame grab. As you say, you've got a very accurate scrub ability but once you're on your frame of choice, how d'you grab that one frame ?

Well, what I would do...
Slow the video down.
That will add bookoo frames and make your task easier.

Then use the fullscreen option, and drag your finger along the video track at the bottom.

Pause it, if it hasn't done this automatically, and you can tap the timer on either side of the video track at the bottom for extra fine adjustment.

Get it right where you want it, and screenshot it.

Then you can use the photo editor in Gallery to cinch up the top, bottom, and sides.

Here is a Gallery app that not only has a great editor, but if you are on a video and select edit, it allows YouCut as an option.

They work great together.

Also, any videos that are of a format that Simple Gallery won't play- run them through YouCut.

YouCut makes a great video converter as well!

I have used it to convert GIFs to mp4, and done other transcoding with it.

Many thanks for the detailed reply @puppykickr

I must be honest and say that I'd never considered using the screenshot function to take a frame grab of a video. My only concern would be whether the resolution of a screenshot would be the same as a frame grab taken directly from the video?

I've just tried a direct comparison between taking a frame grab direct from the native video player and then a screenshot of the same frame within YouCut and the screen shot has a slightly lower resolution.

I must say that, to the naked eye, it's almost impossible to tell.

I've downloaded Simple Gallery Pro too and will give that a go in conjunction with YouCut, thanks for the recommend.

One last thing, when you said...

...I don't have a timer showing on either side of the video track at the bottom of the screen. I've got 'mute clip audio' on the left-hand end and the total duration of the video on the right-hand end but no where I can tap for extra fine adjustment?

Yes, I have noticed that the media quality does diminish.

Although to most it would most likely be acceptable- barely perceptible even- it is there, and is noticeable for those of us that look for such things.

And yes, a screenshot will most likely have even less quality.

I have, but have not tried in this way, a screenrecorder app that also will perform screenshots- and has adjustable quality standards.

This screenrecorder, which I have used for a long while, began as ad-free and went on to contain ads.

So I still use an older version that does not have ads. Whatever additions/changes have been made in later versions I do not know.

So here is another cool app for you to play with.

As far as the timer not showing up on YouCut, my earlier response was a bit out of order in how to get to it- I was very tired from work when I wrote it.

Before you go into fullscreen mode, the time on each side of the video strip at the bottom is what I was referring to.

Cut/trim the video to the part you need (do not 'save') and use the video tape at the bottom to move the view to approximately what you want.

Now tap the left time and adjust to the tenth of a second for the begining and then do the same with the right time for the end.

Notice that the total video time must be longer than 1 second.
