Individuals files - still problems!

PostSat Dec 09, 2023 12:51 am

Why hasn't this been fixed yet. Been addressing it years ago, so I want to see if it was fixed yet... and no still not!

First clip, has 16 frames MORE than it should!
Second clip has 13 frames MORE than it should....

Also gives extra frames in the END of a clip!

What is weird, is that the audio, takes ALL tracks and not the selected tracks, but also the muted ones!
In the clip, where I didn't do the individual clip, there it is perfect!

I'm guessing this is a compressed H.264 video format. Those are always wonky in any editing system, because their definition of "frames" is unpredictable. I bet if you transcoded it to a simpler format, like ProRes 422 or DNxHR HQ, you'd have much better luck.

Trying to get accurate time counts from non-timecoded sources -- particularly with variable speeds or non-standard speeds -- is problematic. Even worse with (say) a smartphone, where it's probably variable framerate.

If you want it fixed, make a reproducible test case: This specific input file, these specific output settings etc

It uses the SAME file to make the perfect cut! I think it is BUGs in program!

And no, individual clips does not give extra frames at the end, just tested.

So, with a lot of users not having problems and one user having problems, the probability that it's a bug with the program is low.
That requires you, dear Claus Meyer, to be very specific and detailed in what you do, what you expect to happen, what happens, mediainfo about all files etc etc etc.

Well YOU are on a WINDOWS program, I am on a MAC!

And when I want to use individual clip, I want it to take from the first frame of the clip and end 1 frame before the clip, AND that it takes the sound I say. It does all this in SINGLE clip, except 1 frame in the end where it takes next clips start, when using in/out to set the single clip!

I can’t reproduce that here on a Mac either.
Can you post a small archived project to show the issue?

Try making a screen rec with quicktime, or use h.264 or h.265. since these are the files I have to cut down for archive. I had the problem since I start using DR, and I was hoping v.18.6 had fixed it!

But it looks like real DR people is not wasting time here on forum, so how can they see it is a problem!

dude... relax...

people here are trying to help you, but as long as you don't give proper info, you're still shouting at clouds...

it's stated over and over here in the forums that h.264/265 isn't a good format for editing due to the way it is converted. Most of these videos are variable framerate and DR isn't really good with this. Or any editing software.

you can help us out and try different things:

1. make a little project with the files, and upload it for people to see what's going on.

2. transcode the files into something with fixed framerate and see if the problem still exist.

3. explain - in detail - what files you're using, how they were created, what you're doing -exactly- to see these 'bugs' show up.

now... breathe in.... and start testing ;)

That part is Operator Error and will never be "fixed".

When you use a shortcut to move the playhead to the next edit point, you are necessarily looking forward to the first frame of the next clip. If you set an Out point there, then you get the results you describe.

There are ways to overcome this behavior, if you're interested.

If I want INDIVIDUAL CLIPS from a timeline. Then ofcause I dont want a frame of the NEXT clip in my clips!

and I really dont want to discus how things should work with people NOT working for Blackmagic.

They havnt even added a "loop" recordere in the ADR. You still need to fix it in Avid Pro Tools, which is the only program I know has this "dubbing" function to make ADR fit 100%.

Now I can reproduce your issue! I was still wondering why I never saw this problem here before, and we have clients who are exporting individual clips regularly.

I got some clips from a drone that doesn't write TC and they behave like you describe.
So, Marc's assumption that DR can't handle clips without a TC correctly is correct.

I then added TC with the help of QTchange64 (I suppose Shutter Encoder would do as well) and they work as expected. Case closed for me, I don't expect BM to fix this. But you should never loose hope, maybe Avid can handle these.
Maybe AI can help you. Or make you obsolete.

In fairness to Resolve, clips without timecode are a nightmare for post. The advantage of copying all H.264 files to ProRes 422 or DNxHR SQ is it gives them "phantom timecode" that essentially starts at 00:00:00:00 and will stick with the project. I've said for years and years that Long-GOP H.264 is bad for post, period.

Second that.
But if Claus hates to convert (you suggested that solution before), this might help.
I'd suggest re-wrapping to .mov while adding TC, since it has it's own TC track, while TC in MP4 is not very well-defined.
BTW, for better organisation, one can derive pseudo-TC from the creation time, so you see the clips in sequence of recording.

PEOPLE STOP TALKING ABOUT WHAT CODEC IT IS!!!!

WHEN I DO THE DELIVERING OF THE FILES AS SINGLE FILE, THERE IS ABSOLUT NO PROBLEMS WITH THE FRAMES. IT STARTS AND STOPS, WHERE I CUT IT. PROBLEM IS WHEN I WANT TO "SAVE TIME" WITH 100 CLIPS!!!! AND NOT DO THIS MANUALLY AS AN IDIOT. THEN I HOPED INDIVIDUALS FILES, WOULD DO THIS TRICK, AND IT DOES NOT. (SAME FILE, BUT THEN PROGRAM STARTS BEEN USELESS, CUTS BEFORE THE CLIP AND ADDS FRAMES SO THE NEXT CLIP IS IN THE FIRST CLIP!!!!

IF SOMEONE REAL FROM BLACKMAGIC IS HERE!!!!! CONTACT ME INSTEAD OF PEOPLE COMING UP WITH OWN IDEAS WHY YOUR PROGRAM DOESNT SUCK A-S-------- S!!!!
