Jagged edges in video

I just upgreaded to HD - I use Sorenson Squeeze to compress. I DO de-interlace. When compressing to mp4, when someone moves Im getting a jagged line on the subject that is moving. Any suggestions?

Well, DV is lower field first.
But this is normal. When you de-interlace you are left with jagged edges where the individual field lines were. It is most noticeable with graphics/text and fine edges. Trust me I deal with this ALL THE TIME with my clients. They make commercials that are interlaced for broadcast, but almost ALWAYS watch their own material on computers. But they hate interlacing lines AND jagged edges... it is lose/lose.
Anyway your best bet is to use the best quality settings in compressor for de-interlacing. But you'll never get 100% rid of it. Sad fact of interlacing sadly.

Aliasing, excessive digital stepping, jagged edges on video

I am working on a project shot on HDCAM shot at 23.98p. Exporting out of FCP using Compressor I have been getting a number of shots with excessive digital stepping. The stepping occurs in narrow dark vertical lines surrounded by excessive brightness (in this case windows where the exterior is blown out) when I export from compressor to burn an SD DVD (see settings below) in DVDSP. I have tried the anti-alias controls in compressor- but the images loose all sharpness, take very long, and just go blurry, the same is the case when I tamper with the original using FCP's effects anti alias. Both tools only blur the image, and stepping still remains. I understand some stepping is normal here and there, but this is severe, and distracting. I have viewed the output on several monitors a 27' SD, and on a 32' HD. The original HD footage does not step on the computer monitor (apple cinema display) or on 32' HD. I have also tried darkening, lowering the contrast ratio, and creating blur/ anti alias mattes, but have had poor results. The darkness and amount of blur needed to emiminate or minimize the problem is too severe, and the image is unusable, while only minimizing the stepping. How can I eliminate the Digital Stepping, and maintain sharpness, brightness/ contrast?

Since you didn't mention is specifically what were your other settings for Compressor's Frame Controls? (you mention touching on Anti-Alias, but none of the other settings)
The tab should be set to Custom, and the Deinterlace filter - in ther Frame Controls tab, not the Filters tab - should be set to Better (Motion Adaptive).
(At least that's what I recall having provided me with the best output/time spent balance in the past, even though you'd think that the Deinterlace filter wouldn't apply to Progressive footage)
Also, have you tried this without the Letterbox filter? I've found that the Filters in Compressor - outside of Gamma Correction - tend to compromise video quality too much.
And finally, any reason that your bit rate is so high? 6.8 to 8.0 is, in my experience, way high for DVD-R (in terms of playback compatibility).

Video has jagged edges

I've just burned a first dvd with my new mac book pro and final cut express upgrade. The video shows jagged edges all through. It seems fine in the editing program and viewing in the dvd. What can I do to correct this problem.

sorry meant to say that it works in idvd. When viewed on the dvd player or computer it looks very jagged.

Images imported from QT exported image sequence have jagged edges

Hi
I've come across something strange which I'd like to resolve.
I export an image sequence from QuickTime.
I then import this into Aperture.
But the images imported into Aperture now have jagged edges where there has been any movement in the original footage.
The images originally exported from QuickTime look absolutely fine when viewed with preview, they have the expected blurring on moving objects, but no jaggedness.
Now, a bit more detail.
The footage I'm exporting from was shot by me and came from a Final Cut Pro edit.
The codec in the QT movie is Apple Intermediate Codec and this is interlaced.
The jagged edges on movement look to me like the problem of interlaced not being converted to progressive.
However the exported images from QuickTime don't display this when viewed in Preview, it is only when viewed in Aperture that the jagged edges become apparent.
I have tried exporting from QuickTime to jpg, png and psd, but the problem is identical no matter which format I use.
I really want to now use Aperture to improve these exported images, but with this jagged edge problem I can't.

Hi JNorris--
Sounds like you need to apply the deinterlace filter (Effects tab: video filters: video: deinterlace) to the stills your exporting.
See if that makes a difference to start.

Jpg jagged edges

Hi,
I'm making a video from jpgs -- all were taken by a professional photographer, really big file sizes, so that they are down to about 26% to fill the screen. Problem is the jagged edges, particularly on straight lines -- and there are a lot of these because it's architectural photography.
Tried Gaussian Blur in FCP, but it softens the photos too much.
Any other ideas?
thanks,
Eve

Let's try this from the top.
Recognize that NOTHING on the TV will ever ever look as sharp and as detailed as the original images.
1. A pro photographer should be able to deliver files in TIF or PSD - lossless formats. JPG is a lossy format designed to compress images for transmission over the internet and display on computer monitors. It was intended to be used by people who care more about small file size than maintaining image fidelity.
2. Unless you are doing moves (pan/zoom) on the images, you should reduce their pixel count to something close to the codec size. For DV, the equivalent square pixel size is 720x540. Best to do this in Photoshop (or other image editing software) before importing into FCP as FCP does not have the most sophisticated scaling engine.
3. Deinterlacing still images makes no sense what so ever. Deinterlacing takes half the image and throws it away then adds back the missing lines of information interpolated from the remaining lines. Why would you do this on a still image?
4. Images with a great deal of contrast and or thin horizontal edge detail will benefit from a slight vertical gausian blur - .5. This will make the detail that exists on only one scan line (which may appear to vibrate) blend over two scan lines so the image will counterintuitively look sharper - or at least more stable. Setting the Field dominance to "none" will also help as it tells FCP to render by frame not by field.
5. Keep in mind the color space of the DVD is the same as DV - 4:1:1. Unless you are manipulating the images (color correcting, composting, overlay titling, etc) your images will not improve with ProRes or DV50 codecs and the editing file sizes will grow significantly. If you are engaging in those activities, you will see a benefit.
6. Unless you are planning to make some variant of an high definition DVD (currently Blu-ray), it doesn't make any sense to me to work in an HD format for editing then down convert to DV size for burning. Why not simply work at the size/aspect ratio of the final output?
7. As noted, you really MUST have a TV monitor connected to view the material as you edit/play it back. Otherwise, you will have no idea how your work will display without burning to disk.
Have fun.

Jagged Edges

Hello,
First of all, forgive me but I am a complete newbie who's new to the world of Final Cut and video editing.
Here's my problem: I captured a bunch of footage from a Sony consumer video camera. But when I look at it in quick time and on final cut, the footage has a lot of jagged edges, specifically when the camera moves.
Did I do something wrong when I captured the footage? Is there a way to clean this up?
I'm using FINAL CUT PRO 5.1.
Any info would be greatly appreciated.

You are in all likelyhood seeing interlacing which does not display correctly on computer monitors.
What format does the camera shoot? If you are unsure, post manufacturer and model information.
The next step is to make sure that FCP is set up correctly for the camera's format.
Even then, you will still see interlacing, it is a normal aspect of many video formats that are designed to be viewed on a television screen.

Clip within a clip equals jagged edges

I have placed an video clip (Dad) incide of another video clip (son) to look as if the Dad is coming in over a video telecast on a black laptop. Problem is I am seeing jagged edges along two sides of the Dad clip. Is this caused by aliasing? Is there a way to smooth out the edge? Thanks!
alex

First, are you looking at the output on an NTSC monitor or television, or on your computer screen. The computer screen will not give you a true look at your final product and this type of issue is often "not really there"
If it is "really there" after checking output on a monitor or television, you might try feathering the edges of the "box" (MOTION > CROP > FEATHER EDGES)

Jagged edges on text

My text has jagged edges after I render in FCP 4.5. This also happens when I import files from After Effects and Live Type. I recently lost all of my sequence and render settings, so my thinking is that it's one of those settings. Any ideas?

By default FCP sequences are in the DV codec which looks as if it loses resolution when viewed on a computer monitor. If you're outputting your video to an NTSC monitor via firewire, DV should look fine ... you must be looking in the Canvas.
(DV doesn't really lose much resolution on computers ... if you open a DV video file in Quicktime & go to Movie Properties-->Video Properties, you can select "High Quality." The Powers That Be at Apple so ordained this setup because computers used to have trouble playing back full-resolution video at 29.97 fps ... not really the case nowadays but they keep playing DV at "low quality" by default.)
If you change your sequence codec to Animation it will look sharp & crisp. But be careful, Animation files will eat up space on your scratch disk like CA-RAAAAAAZY. So either you need oodles of space or short animations.

Jagged edges on photos.

Hello.
I got a huge problem when trying to incorporate pics in PSE12.
I have downsized all pics to 2000X1500 using PS.
My problem is that the photos comes out with jagged edges and really bad quality.
I have tried all sorts of things. Saving it to PC helped a little but still jagged edges and overall really bad quality.
Tried different sizes, still same.
Even tried downsizing to 720 and burn to disc, playback on ps4. Still same.
The quality of video is fine and looks alot better then Pictures. I can just pause the video and it looks
crisper with no jagged edges.
I have never experienced this Before with older versions of PSE.
And No! This is not a resolution issue. I know they wont look as crisp as original
photos but they should be on par with videoquality and as of now they are not.

Vinjack
Just what program are you working with - Photoshop Elements 12 or Premiere Elements 12. The "PSE" abbreviation is typically used with Photoshop Elements.
In order for us to help you, please clarify your posting. If this is a Photoshop Elements question, you have posted in the wrong forum. You want the Adobe Photoshop Elements Forum (photo editing) and not where you are now the Adobe Premiere Elements Forum (video editing). It is your mention of "Timeline" incorporated in the "PSE" description that is confusing. By any chance are you working in the Elements Organizer Slideshow Editor of a Photoshop Elements program? Do you have any version of Premiere Elements at all?
Looking forward to your follow up.
Thanks.

Jagged edges on pics

Did a project using yearbook pages for a customer, I tried scanning and taking digital pics, scanned pics had odd ghosts on the pics, and eventually used digital pics, but even they weren't all that good, mostly because the headshots were quite small, and I got jagged edges on shoulders and heads. Tried some filters but nothing really helped. Project is done and out, but I still wonder what could be done, was it just the small size of the pics?

If the images were small, there's not much you can do with it once it's in a video editor (unless a slight gaussian blur suits your fancy -- it wouldn't mine).
Your better bet is to try to blow the image up first in Photoshop or something similar before it gets to your video editor. There's a PS plug-in called Blow Up (www.alienskin.com) that's pretty good; supposed to be better than just blowing an image up in Photoshop. Still, if you're starting with a tiny image, there's only so good it's ever going to look.

Jagged Edges on Raster Images in After Effects/Encore

I've been working on a project that uses movie files made in After Effects and then brought into Encore to create a DVD. The problem I'm having is jagged edges appearing on raster photo images - things like people's chins especially look jagged. All looks ok on my monitor/computer, but once I watch it on my flat screen TV I get these jagged edges. I've tried transcoding Progressive in Encore but that didn't help.
Someone please help me!!!

Yes, it's MPEG compression, and no, there is no "flip a switch" magic cure. Probably what happens is:
- you are not suitably color correcting your image, resulting in oversaturationthat's bad for compression
- you have thin lines and only slightly angled edges on the photos
- you are not using motion blur
- you have overcranked our TV's colors
- the TV does some image processing/ scaling/ frame rate coversion
These ad a million other things will conribute to percception of poor video, but as I said, geerally there is no simple solution here. Compression isunavoidabl, but there are of course ways to improve the results. You should do a little reading up on this. O the AE side you may improved by choosing suitabe renderr settings, using a tiny bit of blur, enabling motion blur, chnaging the motion of the items, adjusting their colors - whichever works. Again, no geeral recipe here. Good compression is a art we all have had to learn over the years ad the best advise can't replace persoal experience.

Jagged Edges - When compressing 50 minute clip - burned in DVDSP

I'm in the process of authoring four DVD's (mixed martial arts, muy thai etc) which was shot in HD on a Panasonic HVX-200 using the DVCPro HD codec, at 24 fps progressive.
2 of the four DVD's I'm having problems with jagged edges around the two fighters (two guys shot against a white backdrop), you can clearly see blocky artifacting around the edges of them.
I've tried exporting via compressor using a 1-pass VBR 6.2 Mbps min - 7.7 Mpbs max, imported into DVDSP, build the project, and then when I use the DVD player program, I can see the artifacting.
However, I have a couple of other clips on the DVD, that were exported the exact same way, and no artifacting is evident.
I tried re-encoding at a CBR of 7.7 Mpbs, no change. Any ideas?
One thing that I just thought of is that I have been using the same source folder when building the project as the previous versions (to save time rebuilding all the motion menus, etc). Could that be a reason? Would DVDSP be using some of the information from the older encoded video?
Any thoughts please.

Make sure that you are encoding for 24p. Set the video format for 720p, and the frame rate for 23.98. You should also be using 2-pass VBR, not 1-pass.

Jagged Edges and Unstable Images when converting from Image Sequence to DV

Hi,
I have an Image Sequence (very good quality) that I'm trying to convert using Graphic Converter into DV NTSC Video.
I chose Progressive scan.
I find that the Images appear to have Jagged Edges especially when there is movement involved. Also, the entire image as a whole appears to be Unstable/ Vibrate Slightly.
Does anyone have Experience with this?
Thanks,
Rajnesh Domalpalli

Ntsc dv should be interlaced. also if you are viewing on a computer monitor the footage will appear nasty. It's best to view via an NTSC monitor.Do you have Final cut? if your images are correctly sized you should be able to drop the sequence into a final cut sequence set to DV NTSC and render out the resulting video. You will likely need a multiformat monitor as I believe the standard in India is a PAL variant PAL B not NTSC . in NTSC the screen is filled first by odd lines (Field1) then by even lines (Field2)thus a single pixel line will appear to turn off and on as the screen fills between odd and even lines. Straight lines and angled lines exhibit aliasing and flickering particularily when viewed on a computer monitor because computer screens fill the screen progressively from top to bottom and at a much higher refresh rate than NTSC. hope this helps

Exported Images Have Jagged Edges

I was wondering if there was a way to eliminate the jagged edges on images exporting from a sequence in Final Cut Pro. I want to use stills from my video as the menu background for my DVD and I want to have as nice of an image as possible.
I am working in SD with video captured from a Sony VX2100 if that makes a difference regarding quality.
Thanks for any and all help.

Hi JNorris--
Sounds like you need to apply the deinterlace filter (Effects tab: video filters: video: deinterlace) to the stills your exporting.
See if that makes a difference to start.

AE CS6 having problems with jagged edges in my render

I used to compose videos together using After Effects CS4 and the default settings for rendering produced good renders, but after I've upgraded to the CS6 version I notice jagged edges problem in my renders that I didn't have in CS4, and i'm using the default settings in CS6.
This is a screenshot of a video rendered using CS4 (default render settings):
This next one is rendered using AE CS6 (default render settings):
I have looked into the formats that both versions render at and tried to figure out what the difference is. To start off, the available formats given in CS4 seems a lot more different than those in CS6.
-CS4 rendered in a "Video for Windows" format by default and in Format Options it is Uncompressed, while CS6 doesn't have the "Video for Windows" option at all (and I can't find AVI format for CS4).
-In CS6 the default format is "AVI", and the Video Codec inside Format Option is "None" by default.
I'm not sure if this is why CS6 produces jagged edges in its videos. Does anyone know what I can do to render sharper videos in CS6 so i can stop using the CS4 version?
For example should I maybe change the format from AVI to something else? Change the Video Codec from None to something else?

Well, straight up: Have you ever bothered to read the AE help? No offense, but this really sounds like "I use the default settings, but otherwise I don't know quite what I'm doing." AVI is cunningly called Video for Windows proper. the rest makes no sense. You are not telling us anything meaningful like comp settings and so on or how you verify your output. The second image simply looks like the hardware scaling in the comp viewer at odd zoom rates and resolutions. Anything beyond that will require a lot more info.
