Horizontal lines on 720p HD video

Hi guys,


I would be incredibly grateful if you could help me finally get this project finished, which I have been working on for months. I have read lots of other threads trying to solve this issue but either do they not solve my problem or else they'reout of my depth technically, so I require a step-by-step explanation.


I have the dreaded horizontal lines on my final cut pro timezone preview as well as my rendered finalized video. I have never had this issue before and I have been using the same camera as always (Sony HDR-CX130).


I have read about de-interlacing, but my clips already appear to be 720p rather than i.


Some additional information:


This is what the problem looks like (especially visible in the area around the boat, everytime there is horizontal movement):

These are my settings:

This is what I see below my time line:

Another problem I haven't had before and that might or might not be related to this is that rendering the project suddenly taking forever. It jumps from 0% to 5% immediately and then sits at 5% for hours before moving on. To give you an idea, rendering a 23 minute project took about 7 hours today.


Thank you so much for your help and time!!

You shouldn't be shooting standard definition with that camera. Make sure you check the settings so that you're shooting AVCHD.


You can google anamorphic.


Do a small test. Make a new project and leave the settings on automatic to set the project properties on first clip.


Put a couple of clips into the project. Then open project properties. What does it say?

From the screen shots that you posted this is what I think:

You created a new Project but used in it the original Event that you set up to import your original video. It was these original Event import settings that ( I think) were somehow wrong - I think. By allowing FCP X to import your video set to automatic, it should do so with the original frame sizes and other characteristics. I think.

It would seem from what you have posted that you originally shot SD Widescreen (Standard Definition) interlaced then tried to change those settings to 720 P. Is that right? If so:


Perhaps... SStart at the beginning. Put a card from your camera into your card reader and then control click on the actual .m2v or .mov or mp4 or AVCHD video on the card and open it in Quicktime X Player. This way one can see for sure what video you have to work with.


Tom is right, tho you can, you shouldn't be setting that camera to shoot SD since it can shoot HD.


I also recommend downloading VLC Player. It will open and play any video in its original glory with details.


It is all a bit confusing which gets cube rooted by trying to use the written word. Also, Tom knows his stuff so I do not want to futher confuse all this - so I'll leave you & him to figure it all out. Just thought I'd add this last bit.


Try to stick with this. Be methodical. Don't get discouraged. You are getting a brilliant crash course on "everything i needed to know about video but was afraid to ask."



Good Luck

I just wanted to say, thank you so, so much for both of your help! I have to admit, I was getting very discouraged last night, because I only understand a small percentage of what Tom says and I don´t want to be a burden, Tom. But your words, babylonslim, really put a big smile on my face and you are right, I am learning a lot, even if I only understand half of what I´m doing here.


I already have VCL player, it´s really the only player I use, hence my lack of knowledge regarding QT player.


Also, I have checked the settings on my camera and it appears to be set on HD.


I will try everything both of you said and let you know how it went. I can´t stand the thought of this project not getting finalized, after all the work I have put into it.


Thanks again, it´s nice to see there are still people out there who use their time to help others without any benefit to them personally. I really appreciate it to the point that I´m nearly embarrassed.

Okay guys, here I am back now. I have done what you suggested:


Tom:
"Do a small test. Make a new project and leave the settings on automatic to set the project properties on first clip.Put a couple of clips into the project. Then open project properties. What does it say?"

babylonslim:


"Put a card from your camera into your card reader and then control click on the actual .m2v or .mov or mp4 or AVCHD video on the card and open it in Quicktime X Player."

QT Player won't play the file unless I pay them 20 bucks, due to an unsupported codec. It´s an MPG file. Opening it in VLC player its already very ¨stripey¨:

This is all the info I can get out of VLC player:

I just did another test and connected the camera to the tv directly to play back the recordings and the quality was perfectly fine. No horizontal lines at all...


Any wisdom?

Thanks :-)

The first image is for an SD not an HD project.


The bottom image is showing the audio stream information only. Nothing about the frame size or the video stream.


The media is clearly interlaced and not progessive. It's not 720p. It's 576i or 1080i, unless the camera is shooting some other non-standard bastardized version of video, which some manufacturers unfortunately seem prone to do.

OK, in the same window in VLC that you found and expanded Stream 1 -- which is audio,

go back to VLC/Window/Media Information/ :

Please make screen shots that show:

1 - General



2- Codec Details (expand the arrow for Stream 0 ONLY...( Stream 0 is your video info, Stream 1 is audio)


You just didn't tick the Stream 0 disclosure. We need to know that info.


This is directly from your card/camera right? Not after FCP or any other editing or conversion software has had its way with your video. Right? No clipwrap, No any video convertor, No best video convertor, No aunsof or brosoft, etc.


You are almost there.


Good Luck

Hi again guys,


sorry for the delay, started a new job last week. Thanks for being so patient with me!


I have the info you needed:

What confuses me is that I have made videos with iMovie and then with Final Cut Pro before and I've never had this issue. Sometimes the lines appeared when I played the raw video on my computer but as soon as the movie was finalized it was fine. I really did not change the settings on my cam so how come this is happening now? Can I send you photos of my camera settings? The following looks like what we're after? It says component 1080i/567i. Other options the cam gives me are 1080p/576i and 576i.

Thanks a million again!!!

Ok. -- Hopefully Tom or someone else will offfer more help. Here are my opinions:


You have 2 issues, the first being the most important right now:


1. You have shot some video with your camera at a less than optimum setting:

SD (720X576) 50 i -- or at least that is what VLC is reporting. To this issue you need to either (a) convert that video outside of FCP X to make it "look" the best it can. (b) import it into FCP X making certain that it is imported as it is. Up until now none of your import settings have not matched what VLC shows - SD 720 X 576, 50 i. (If you do this, you can hopefully export out as 50 P thus removing the interlacing ) --- I think.

Now, I have never tried this but I have seen other folks try to get rid of interlacing upon import - perhaps that works, but since I always remove interlacing AFTER I edit, that is what my advise id based upon.

Another option right now that I would at least try if I were in your situation is to use Mpeg Streamclip to transcode your video to progressive Pro Res 422. Download the beta ver. 1.9.3b8. You must buy the (QuickTimeMPEG2.dmg)

espeacially for your camera. Follow the instruction where to put it:

Mac Hd/System/Library/Quicktime/

(If you do not have the apth above, domnload Quicktime 7).


2) You need to learn at what setting your camera shoots the best video in HD. Try setting your camera to shoot test footage of a car driving by you at 1920 X 1080, 25 P, 1920 x 1080 25 i or at 50 I & P. Whatever settings you got, try each one on the same cars driving by in the DAY. Make sure NOT to put more than one test setting on a card. Set, shoot, copy the cards contents to a folder on your computer, make written notes, go back outside and try at a difeerent setting, repeat. Please read up on the difference between interlaced and progressive and Google your camera model + poor image quality followed by a "?".


I know that all of this "reads" very complicated. Just take it in bite size portions, use Google read other discussions and POST BACK here with anything - no matter how "insignificant" I for one want to know how all this turns out for you.


Good Luck
