adjusting fps - by: meirjac Thank you!!! ]]> Codecs / Importing / Exporting / Transcoding Mon, 20 Oct 2014 15:29:21 +0000 poor quality MOV export - by: C6
I have made a short video which exports well to the YouTube format. It looks great.

However, when I try and export it to MOV, the quality is poor. It seems to output to a very low resolution. The source file for the edit is ProRes which looks great while editing.

An AVI export file looks great too.

I need an 480i SD 720x486 MOV version of my edit. Why does it look so bad?

I believe I used the DV/DVCAM setting. Is that the problem. Shouldn't DV/DVCAM look at least as good as miniDV?

Because I am not at the machine I used to make these files I cannot send you a MediaInfo analysis.

I am on a PC, Windows 7, LW Pro 12.

Mov. import problem - by: scottapreston
First let me apologize for posting a stupid question that has been treaded over in the past. With that said I am in a country where the internet speed is extremely prohibitive, connection strength is generally low and rolling blackouts are frequent. In trying to solve my problem I've already spent all day trying to read through the forums and I've encountered a dictionary's worth of terminology that I dont understand (I barely understand what a codec is), which would again take yet another day to work through at this rate.

I've been trying to create a time-lapse video in iMovie, but even with the lowest levels of compression the exported video is horribly pixilated, especially in the dark areas. That brought me to Lightworks.

I'm trying to import my time lapse videos, some import and some dont. I've tried different frame rates and I'm still having an issue. One clip in particular has been problematic. When I try to import it the file is green and then displays noise when go to play it. the info is below:

Could someone please explain to me, in laymen's terms, the steps I should take to make this video usable? For example, if the problem is a codec problem, what do I need to do to change the code? Again, sorry for the question, I hope you understand, please dont hate me, thank you for your time.]]>

Exporting as interchange R3D timeline into Redcine X - by: androidphrases
I am trying to export my edit (R3D red epic 4.5K) into Redcine X for a grade. OMF produces and error in Lightworks, AAF crashes Redcine, EDL's don't import the video files and don't seem to contain the file names anyway.

I would like to use an interchange as the R3D files are not moving into a different machine, and I would like to bring the graded shots back into Lightworks as R3D's with handles rather than render them out as anything else.

Can anyone suggest anything?

Thanks in advance

Dissolve Frame Swapping - by: Subasean
I've been having these issues for a few months now, but I'm trying to take my edits to a new level and can't ignore this anymore. I've also spent the past few weeks trying to find similar topics to keep from wasting anyone's time, but no one seems to be describing exactly what I'm experiencing.

Using: Lightworks 11.5 Pro

Video format: FRAPS uncompressed .avi (variable framerates, which I'm beginning to suspect is my problem)

Issue: When implementing dissolve cuts, sometimes when transitioning to between trimmed sections from the same imported clip using a dissolve, I'm getting frames from before the dissolve inserted into the back half and frames from after into the front half, creating a "flicker" effect instead of a smooth transition. My trimmed sections are no less than 30 seconds long, and my dissolves are set to 30frames, centered at the cut. The software I'm capturing places high physics demands on my processor, so my source videos are sometimes captured at less than 30fps, sometimes as high as frame-limited 60, so I'm concerned that this is my primary issue, which I'll not be able to do anything about.

I've been trimming my video in the timeline, as well as moving marked sections from a separate viewer window. I've tried alternating video tracks for my clips as well as doing them in-line. The first transitions in this timeline are perfectly smooth, but as it transitioned into the green segments I started getting loose frames, hence the trying to experiment with alternating video tracks, which did not help, I just got desperate.

This image is hidden for guests. Please log in or register to see it.

These sloppy transitions survive through encoding to the final product, and while I was not inclined to care that much, reviewing my work has shown just how badly these impact the final product.

Any thoughts? Am I in the right ballpark with my framerate concerns?]]>
