Interlaced video flicker question

Hi,
I recently worked on a DVD project using the complete Final Cut Studio and authored using DVD SP 4. There was a problem with the finished video that I could never quite clear up. I shoot using MiniDV and edit on Final Cut, then encode my video using Quicktime Pro. Well, my finished disc looked amazing. However, I noticed when I moved my camera if the subject was wearing red (or any red in the picture for that matter) there would be some interlaced flicker around the edges of the red color (it also occured around the edge of a few other colors, but mainly red and only when my camera moved). I'm just curious if anyone has encountered this and if they can offer any help to correct it.
Should I have my FCP timeline set for progressive scan? Is there a way to set a SD NTSC video project to progressive scan?
Thanks, Jason

Sounds more like a colour saturation issue... reds are very prone to 'bleeding' around the edges...
You should use the vectorscope in FCP to check all your colour levels are safe. Red is especially problematic.

Can you convert Interlaced video to Progressive?

Does anyone know if there is a way to simply convert interlaced video to progressive video? I don't have Apple Compressor, and don't know of any other way to convert interlaced to progressive. Any ideas?

I am clearly not the best person to answer this question...but.
Depending on why you want to change interlaced to progressive, there are several ways to approach this.
There is 3rd party software like the previous offered, and a few others, but if you are simply going to upload to the web or show it on other computers I would just export the movie in a progressive format, using export> Quicktime Conversion. Then select the settings you would like to use.
Hope this helps.

Why does interlaced video have vertical black bars?

Despite looking all over the internet and asking video editors I know, I've never yet found a satisfactory answer to this question:
When I bring DV PAL footage into my Mac, why are there always very thin black vertical bars on each side? And why is the image being squeezed slightly?
I think it may have something to do with interlacing.
If you look at my screenshot here.
You can see that the top image (QuickTime 7 Player) exhibits the issue I'm talking about (the prescene of combing on the man shows this is interlaced).
But the black bars have disappeared in the bottom image (QuickTIme Player X) - and you can see that it looks slightly horizontally stretched by comparison. I'm guessing this is something to do with the fact that QuickTime Player X DE-interlaces video.
The question remains though... what is it about interlacing that introduces black bars and an incorrect aspect ratio??

If you are ripping "standard" format content (4x3 ratio) then it will just appear like that on a widescreen TV. You shouldn't have that problem if you're ripping widescreen content (16x9 ratio).

Video Flicker

We are using adobe production premium cs6, this being used on Mac pro, lion os 10.7.4 with matrox mx02 max card. We facing a Video flicker issue on clips captured using VTR or clips taken as data to adobe premiere? Please advise how we can overcome this flicker issue. We have tried field change and flicker removal on adobe but seems nothing working.

Hi, a few questions that will help us to help you-
Format/source of video being captured?
How is it coming in (analog, HDMI, etc)?
Sequence/capture settings?
Where do you see flicker - in Premiere Program window, or on MXO2 video output?
Thanks

Mice Teeth! Interlaced video!

I record on PAL 720X576 (16:9). I am seeing Mice Teeth as a result of Interlaced video. I have the following questions about this.
1. If I want to output to DVD for viewing on TV, should I be deinterlacing the video while editing?
2. Why don't I see any improvement after using Imovie>share>Export using Quicktime> options>Size>Deinterlace source video?
3. What is the best way to edit/export so that I can watch the video on bothTV and computer monitors?
4. why don't I see video's shot in 16:9 in the correct aspect ratio?

iMovie 9 uses single-field processing when exporting, and discards every other frame unless you take some steps to get it to work.
Have a look at these threads for info re: exporting from iMovie 9 and how to ensure the best quality:

Just bought a 2tb external hard drive with the intention of moving my iPhoto data files on it. I have so much of my 500 gigs being used up by images and video. Questions: Will this foul up my iPhoto app? Do I need to point iPhoto to this new location?

Thanks!

Are you running a Managed or a Referenced Library?
A Managed Library, is the default setting, and iPhoto copies files into the iPhoto Library when Importing. The files are then stored in the Library package
A Referenced Library is when iPhoto is NOT copying the files into the iPhoto Library when importing because you made a change at iPhoto -> Preferences -> Advanced. (You unchecked the option to copy files into the Library on import) The files are then stored where ever you put them and not in the Library package. In this scenario you are responsible for the File Management.
Assuming a Managed Library:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

HELP - Interlaced video playback stuttering!!

Hi all,
I'm having problems with Quicktime playback of Interlaced video. For testing purposes, I'm playing back a PAL 20 second h.264 clip on a secondary display attached to my MacBookPro with the Apple DVI-S-Video adaptor (set to 720x576 interlaced PAL 50Hz).
When I play the clip, it stutters/flickers (almost like the fields are inverted?).. If I pause then play the movie repeatedly (i.e : stop/start with the spacebar) the problem seems to rectify itself for a few minutes and everything runs smoothly, then it happens again, until I pause/play again.
I'm on Leopard with the latest updates.. I desperately need to find a fix for this ASAP as I have a tradeshow install in a couple of days time.. Any help would me most appreciated.
Thx

I've never tried how well interlaced material transfers from the Mac directly to an interlaced TV...
But I do know that feeding interlaced .dv from iMovie (in passthrough-to-camcorder mode) via FW a a TV is fine. Or burn it to avideo-DVD via iDVD and use a standalone DVD player to present it.
Maybe H.264 sometimes loses its field sync? Could you use brute force and deinterlace it and live with the less smooth movements of progressive video?

Using You Tube video clips question:

After importing several clips from You Tube (of varying quality) to incorporate into an editing project, the clips look okay and play full screen, in the "source" window, but when I put them in the timeline and play them in the "program" window, they are thumbnail size. Why does this happen? I tried converting...but still no luck.

The short answer here is, don't. (Assuming that if it was yours in the first place, you'd have the original and not have to use the upload.)
And Bill, you should know better than to help someone violate copyright law.
yeah, i beg to differ on this. i have 100s of videos on youtube i did back when it first started before i saved my finished projects... (from 2005-2008 i would just record, edit, post, delete, because it was just random junk of me hanging out with friends, or just v-logging about stuff i needed to blow steam about) so one of these days i'll have to go through and download them and burn them for archives.

How to export h.264 interlaced video??

hi, my situation is the following: i have a full hd (1920x1080i50) camcorder which gives me just interlaced video clips with 50 half frames per second in AVCHD. i dont want to deinterlace the material, cause it taks too much time, the quality looses and the filesize is doubled (if i want to keep every frame).
i want to cut it with imovie 08 and then export it back into h.264 in interlaced format. (because i want to burn it to a data-dvd and play it in a playstation3. and h.264 is the only full hd format, which the ps3 is able to play, i think).
but in the export preferences i cannot choose between the options "interlaced" or "progressive". and the export with quicktime as h.264 or mpeg-4 is always in progressive mode, ignoring the interlaced material. the result is a progressive video with 25 full frames per second showing 2 half frames mixed together in one frame with the typical "interlaced-lines-error" or in germany we are talking about the "picket-fence-effect". it seemes that imovie does not identyfy the interlaced video automatically.
the imported videos from the camera are definately imported by imovie as interlaced video. i can check it in the quicktime player by turning on the "deinterlace"-option. quicktime playes the video deinterlaced, the "picket-fence-effect" dissapears. if i do it with a exported h.264 videofile from imovie, nothing happens when i turn the "deinterlace"-option on. the "picket-fence-effect" does not dissapear.
today i already loaded the quicktime update, but i still can not export in mpeg4/h264 interlace.
can somebody help me?? i spent already several days with exporting, searching the internet and burning dvd-rs.
thanks

You should give MPEG Streamclip a try:
http://www.squared5.com/svideo/mpeg-streamclip-mac.html
In this program, interlace/deinterlace is an option for MPEG-4 conversions, although I haven't used it myself.

OS X Lion. video flicker/scramble

OS X Lion. When dragging a file from Downloads folder to desktop I acquire a sudden video flicker/scramble on my display

Ahh, I'd forgotten about that feature since it is not really that easy to find and I always use MPEG Streamclip which does an outstanding job. However, I just tried it with a 10 sec intro I had (the only .mov I had available) and it did not work either. I'll be sending in a feedback - may i suggest you do the same.
In the meantime, try MPEG Streamclip - I've used it for a long time.

In frameBufferP is only progressive frame not intelaced frame
Please advise what should I do in order to get interlaced frame.

Video flicker on Compaq Mini 311c - 1020EO in Win 8 (32bit)

Hello,
Upgraded my Compaq Mini 311c - 1020EO to Win 8 32bit and all seems to work except VIDEO Flicker intermitantly.
Tried to load Nvidia driver ( 320.00 and 314.22 ) but when I run the installation the drivers cannot id the hardware as being compatible ??
Please help with some ideas !!

Hello PALaz,
I am surprised you don't have more issues with Windows 8 working correctly on your machine, since it is an older machine. Have you tried to install the driver in compatibility mode?
Visit HP Support and get the Windows 7 drivers for the hardware you'd like to try.
Download the driver to your desktop (your driver is here)
Allow the extraction to complete but close the installation process when it comes up.
Navigate to the C:\swsetup\ folder. You will see your driver listed here. They usually have a name like "sp56737". Navigate to this folder.
Within your driver's folder you will see a "setup.exe" file. Right click this file and select Properties.
Navigate to the "Compatibility" tab.
Click the box that says "Run this program in Compatibility mode for..." and also select Windows 7 from the drop down menu.
Check the box which says "Run this program as administrator" at the bottom
Save these changes and double-click the "setup.exe" to begin the install.
Once the install completes reboot your PC and verify the functionality of the piece of hardware.
Please let me know if this helps.
Good luck!

Importing and handling progressive (non-interlaced) video...

Hi, have searched around and can't quite find the answer to my problem so I hope somebody can help...
Ive recently aquired a Sony TRV 900 (3ccd) which has a progressive shooting option. Apart from a strange semi-strobing effect on that sometimes occurson fast moving objects this option generally seems fine in good light.
I can import into Final Cut Express (v1) ok, and when I view the clip frame by frame (with the arrow keys) every single frame is clear, crisp, free of jaggies etc.
As soon as I play it back (either as a clip or in a sequence) it appears to be lower quality somehow and there is lots of nasty aliasing or jaggies. Pausing restores the image quality back to normal.
Ive messed with various options available when putting the browser into list view. (PAL or square ratios etc). Even tried exporting a final cut express movie, to view in Quicktime but the quality never matches that of a frame by frame playback in FCE. The exported versions if viewed frame by frame lack also lack the higher quality.
I cannot find any sort of interlace or field options during the import stage but as my 'stills' are great I assume it's either the preview playback or the rendered export at fault,but it's driving me pretty crazy! lol
Even though footage may end up on a dvd at some point (ie. interlaced, right?), I would still like progressive versions to create web versions etc.
Am I completely missing the point here or something?
Hope somebody is able to shed a little light here for me?!
Thanks in advance...

As far as i know, Final Cut Express (at least the version i've used which is version 2) assumes you are working with interlaced video and that is that. In Final Cut Pro there is the option to work with progressive footage, but i think FCE just assumes you are using interlaced, and doesn't allow you to change that.
The way you are describing it, it does sound like it is playing progressive footage when in an interlaced mode. A similar thing happens when you play interlaced footage in a progressive mode. It looks absolutely fine when you look at a single frame, but once playing it has lines and artifacts around edges.
I'm not sure if there's anything you can do about that. I'd like to be wrong though.

Interpret interlaced video with 2:2 telecine pulldown as true progressive?

Hope my title makes sense. Not sure how well I will be able to explain.
We have interlaced video files from film telecine. The telecine transfer were made at 25fps as the machines are PAL and this allows us to capture each descrete film frame within the 2 interlaced video fields. I believe this is called 2:2 pulldown. 2 fields for every film frame. The film is captured to V210 10-bit uncompressed blackmagic .avi files. We have films intended to be played back at anything from 12fps to 25fps. Everything is captured at 25fps as the only other available speed is 16 2/3rds fps which creates duplicated fields (3:2) and only works for 16fps content.
So, even though the video file is interlaced (top field first) by combining the fields you get a progressive film frame. Is there anyway to tell Premiere to interpet this footage as progressive without dumping half the fields? As far as I am aware if I work with a progressive sequence or interpret the footage as progressive Premiere will retain the dominant fields and interpolate the rest. I understand this for interlaced content where each field is from a different temporall moment but we actually have the ptrogressive frames just stored as 2 fields.
Any advice appreciated.
Thanks

Premiere Pro will automatically interpret footage that is shot as progressive-as-interlaced, like 25p or 30p, but that (to my knowledge) only works correctly with footage that is from a camcorder. That's because the file is flagged in such a manner that Premiere Pro knows to put the interlaced fields in the correct order for progressive display. I work with 480/30p and 1080/30p footage (which are both interlaced as shot) frequently, and Premiere Pro does things correctly there.
However, I think it will be a different matter in your case, unless the captures are being flagged as they are created. What does Premiere Pro say that the clips' field order (or lack thereof) is when imported? As you've surmised, if this isn't the case, telling Premiere Pro to interpret the footage as progressive is likely going to result in some unwanted artifacts. You could probably test this by importing two instances of your clip, interpreting one as progressive, and then placing them in a progressive sequence (one on top of the other) and toggling visibility between the tracks. You should quickly see if it's having the desired effect or... something else. Instinct tells me that Premiere Pro won't handle this correctly, however.
This might be a job for After Effects, which is a certain degree smarter and more capable of interpreting such things. I'm not exactly sure how to handle it there, but the After Effects forum might be the best place to ask.
