  • I’m exporting H.264/MP4, 1080p, 30fps.
  • Footage is also 1080p, 30fps (camera output from Sony a6400 is seen as NTSC 29.97 in Magewell capture device, pulled into OBS Studio at 30fps and recorded from there at 1080p 30fps).
  • I’ve trimmed the timeline, it does not end on black.
  • If I import that clip exported from Lightworks that has the black flicker at the end into Shotcut and re-export it using the same settings in Shotcut, there is no black frame (or sub-frame artefact?) at the end (tested both by importing into OBS Studio as a media source and looping).


Any idea what could be causing this?

Could there be an artefact introduced due to how Lightworks handles 29.97/30fps? (I just also tried an export in 29.97, just in case it was that and it’s not – I still get the black frame at the end.)

Thanks!

PS. I’m attaching both clips. Clapper.mp4 is the Lightworks export that exhibits the black flicker at the end. clappter-shotcut-export-test.mp4 is that same clip, imported into Shotcut and re-exported.]]>

When exporting, the rendered video text doesn't match original source file - by: marjensenmusic https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221214&Itemid=81#221214 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221214&Itemid=81#221214
When I export the 7-second video, most of it looks good.
However, one line of text looks different than how it looks when inside Lightworks.

The text is white, outlined thinly in gold, with a drop shadow.

When exported, the white becomes yellowish, & the gold outline becomes thicker.
What to do?

Thanks,
Marlyn

what is a good archival format? - by: kalimerox https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221178&Itemid=81#221178 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221178&Itemid=81#221178 www.lwks.com/index.php?option=com_kunena&func=view&catid=12&id=217209&Itemid=81) made me think about a solid and "future proof" export format.

DPX image sequence seems to be the best resolution wise, though it is huge!!

So I would need to find a middle way between maximum quality and storage space ahndling...


The feature I am editing is shot on mixed formats from full HD AVCHD , 4k prores422, some with pro res from a bmpcc4k . it is not a hollywood expensive production at all but i still want to be able to maintain optimal quality. would a ordinary image sequence with .jpg be enough? or shall i go with dpx and fill up some harddrives for a 90min film? thanks!!]]>

Can't import or export videos. Can't recognize frame rate. - by: AisteBielyte https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221176&Itemid=81#221176 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221176&Itemid=81#221176 Second, when I import a 25fps video into a 25fps project, half of it is black. It only happens with 25fps videos but not with 29.97fps. Altho, 29.97fps videos in 30fps project are always missing the last frame. To solve the 25fps problem I use different software to cut a video in half and import two half as two separate files. It solves my problem but it's very time-consuming.
Third, after I finish editing my full video through a lot of struggle, it wouldn't export fully. The exported video has a lot of black screens. If I export the same video in a few different parts, it has less black screens. Full video works fine on a time line. So I don't know what is a problem there.
Lastly, files from my one project somehow appeared in my other project's time line. I edited a thumbnail in a new project and the next day I noticed that it appeared in a middle of my time line of my already edited project. How is this even possible?
I tried to use other editing Softwares and they didn't have any of these issues. What I struggle the most with is that Lightworks wouldn't recognise my 30fps videos as 30fps and that it can't import or export whole videos with no black screens.I, also, crashes a lot it you try to import videos edited with other Softwares.]]>

export 4k looks bad - by: Killer099 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221041&Itemid=81#221041 https://www.lwks.com/index.php?option=com_kunena&func=view&catid=23&id=221041&Itemid=81#221041
I try to export to 4k, my source is 60 fps 4k (3840 x 2160) from a GoPro Hero 7.
So I think this should be possible?

I tried several codecs all the same except 1080p but that is not what I wan't...
Which export do I have to choose? Tried:
H.264/MP4 with DCI 4k, QFHD, QHD all with 60 fps. But video quality is pretty bad.

Thanks
