Hi.

That's great to hear and glad you have it sorted without having to convert your files. I think that is always a better solution if it's possible.

Would it be possible for you to let us know what export setting you changed and to what?

A few screen shots would be nice. It may help us give better solutions to others in future or be able to point them to this topic for a workable solution.

Ray,

@Former user Good 👍 as CubeAce says glad you could fix it without converting the files,. Converting can be as problematic as the exporting issues you've had, pick the wrong convert settings, your files are ruined & you end up in the same position you were in when you posted here, that's a big reason I argue against converting them first, every time files are converted there's a chance of data lost & so with it quality.

Hi Gid

. . . . Logic says a constant clip should play better than a variable clip but to my memory I've never had to convert a file in the past because it was variable . . . .

I do believe the example clips, you have posted from your phone, have a relatively narrow band of VFR, IIRC ~ ±10% maximum of target framerate, the MediaInfo data from @Darynn-Ho phone has an extremely wide VFR band of 15 - 60fps averaging 41.8 fps with a target of 60fps.

Definitely needs converting the CFR, the export settings recommended above I also agree with.

@johnebaker Did you download the Hospital one I shared, does that come within your 10%? A lot of my files are like this, some worse than others, .

Like i say never have I had a definite issue related to variable files, you can't argue about that statement, logic does say that a constant file will perform better than a variable one, but in this day & age I'm thinking this 'convert your media' is a bit old hat. I understand it with Vegas because underneath that is old hat software. but with other software there's 1000s of people out there using their phones to film & not converting their files before editing them, Like i say it's an unnecessary step that if you don't get it right could cause more problems than solutions.

Hi Gid, Ray

. . . . Converting can be as problematic as the exporting issues you've had, pick the wrong convert settings, your files are ruined . . . .

Only if you overwrite the original which you should never do.

As far as your file goes that is even weirder as you have a target framerate of 60fps yet you are hitting 120 fps max - this should not happen, or the metadata is incorrect.

. . . . That's great to hear and glad you have it sorted without having to convert your files. I think that is always a better solution if it's possible.. . . .

I would agree if the audio is not essential or going out of sync is not an issue, however if the audio is essential and must be in sync then conversion is necessary with such wide range of framerate in order to maintain sync.

Hi John. with Gid's MediaInfo data.

As far as your file goes that is even weirder as you have a target framerate of 60fps yet you are hitting 120 fps max - this should not happen, or the metadata is incorrect.

I don't think so as it is set as the target frame rate and as I said earlier such higher tier phones play back such files without flickering because the screen matches the frame rate of the video file on playback as it has an adaptive screen refresh rate to match. To quote some Samsung publicity blurb.

The other important aspect of the S23 Ultra's display is the peak refresh rate, which comes in at 120Hz. That adaptive refresh rate extends your battery life so the phone only uses all 120 frames per second when it needs to.

So one assumes the cameras image processing is able to do the same and go above as well as below the set target frame rate. Phones are unfortunately more advanced in a lot of ways than Windows based computers where processing and operating systems are concerned. Computers currently being hindered by their legacy coding and backwards compatibility requirements where video editing is concerned but capable of variable frame rate viewing via a gaming monitor when playing video games. This all looks like it could change with future Intel CPU designs and Win 12 when it's eventually released. Maybe then all our tech will work and talk to each other without all this hassle. Some monitors are all ready there as are the more recent graphics cards.

@johnebaker  You're being pedantic, I was ref to the converted files which was implied by adding "& you end up in the same position you were in when you posted here", You can't cherry pick a sentence from a paragraph & get the correct context .

@Former user

Hi Gid

I have re-read what you posted - IMHO the sentence I quoted can have multiple interpretations, I interpreted as referring to overwriting the original file which has been known to occur many times in past topics in the forum.

Either way I agree with your statement - wrong conversion settings leading to a worsening situation.

I have just run a bunch of tests on a similar video (attached). None of the solutions made any difference to the blockiness apart from the bitrate. More bits=better image.

If you are constrained by file size (eg Whatsapp) then HEVC at hte same bitrate will produce far less blockiness/artifacting.

I think some of you guys are holding on too tight regarding the VFR issue. Admittedly my experiments have been limited, but even with my old system, I haven't detected any sync issue.

And in this case it appears that the blockiness has nothing to do with the VFR, the GOP, the CPPB or HRD.

As a test, I exported as 1920x1080 at 3k. The blockiness on the water and sky is quite evident. Increase the bitrate to 6k, and the blockiness is reduced. Increase it further and it progressively reduces to nothing. For HEVC, halve the bitrates for the same visual improvement.

@AAProds

Hi Al.

I have definitely had the audio drift problem in the past when testing but only if the clips were cut and edited around where the frame rate varied. Do it multiple times and the sound goes out of sync quite quickly. Straightforward exports do not seem to do that even with clips butt joined or overlapped. The longer the gap in-between the I frames and the wider the frame rate difference, the more out of sync and the sooner the audio drift in those clips become.

Try getting several clips, three should do it if of reasonable length, cut them up and re-arrange them and see if it happens to you.

Personally I dislike H265 because if sharpening is applied as it seems to cause artefacts much sooner and looks over aggressive in the finer detailed areas and not enough happens in other areas.

Hi Darryn, Ray, Al

. . . . H265 because if sharpening is applied as it seems to cause artefacts much sooner and looks over aggressive in the finer detailed areas and not enough happens in other areas . . .

I agree with this, for h.264, 1920x1080 or 3840x2160, I always apply a setting of 30 for the Sharpness option in the Movie Effect setting, Sharpness tab, and for h.265 no more than 15. I very rarely apply sharpening to an individual video or image object - the reason being the sharpening should be the last effect in any chain of effects applied to video or image.

You may find you need to adjust the value for your video/image clips depending on how much sharpening the camera or capture has applied.

Here's a new one - I'm ready to begin making the disc menu, but I had previously used DVDStyler for that. Now it's been a few years and I've just found out that it can't work with Bluray quality videos.

Any suggestions on a good customizable menu creator software? I liked DVDStyler because I could fully control everything.

Mostly what I've seen out there are software examples that have incredibly limited templates, and no way to customize the text or buttons, etc.

Any input would be appreciated.
