Improving bad video ?

Somebody knows out there an app that is able to enhance a bad video like a 3GP for instance ?
Something smart enough that is able to do the trick and add quality by extrapolating between 2 frames or 2 lines for instance ?

You can use sharpening tools like Unsharp Mask. You can use third party up-rezzing tools to increase size with better quality.
But, realistically, given you only have a camera recording of a video screen of the CCTV, it's very unlikely you'll ever extract much meaningful detail from it. Don't believe TV shows, image enhancement is not really so advanced.
Personally, I'd just extract the best still frame of their faces you can find, then use Photoshop to zoom and enhance as much as you can with Unsharp Mask.

How can I flip my iphone videos on my PC? My videos from my iphone are horrible when I transfer them to my PC. How can I improve the video on my PC? Can I just convert the files to WMV? When the video plays the speed is off, it's half slow-motion

My videos from my iphone are horrible when I transfer them to my PC. How can I improve the video on my PC? Can I just convert the files to WMV? When the video plays the speed is off, it's half slow-motion and staggers into normal play. The clips are slightly cut as well, the clips do not roll continuously. I'm taling about videos that are no more than 2 minutes long. I'm frustrated and I could really use some advice-my kids basketball games is what I'm recording and I'm trying to send them to my family (they are not very tech savvy). Thanks

Not it's only function but one for which it was most admirably suited, which is why I really hope someone can find a work around. I am hoping my post to the Apple feedback may prompt a useful response from Apple and I live in hope that my post here will elicit a useful response from another user. I did not miss the the text at the top of the feedback form but you presumably missed my initial text, 'someone here can explain' or my subsequent 'work around from another user'
Just in case anyone reading this has a large collection of music videos, video podcasts or iTunes U then DO NOT upgrade your iPad to iOS 5. If you are considering purchasing the iPad as a useful mobile device to experience these media organised in your iTunes please don't as you will be wasting your money. (unless someone on this forum knows of a way to undo the mess created by those infallible folks at Apple)
Yes I know it does other things but the purpose I bought it for doesn't work anymore

Hey Friends - Trying to improve my video image on Dish Anywhere

Hey Friends - First inquiry to this forum. I'm trying to improve my video image on Dish anywhere app to TV in my home in MI from CO. I installed the new AirPort Extreme 6 in both locations but it does not appear to have improved the quality. Can my old AirPort Extreme 4 be used as an antenna on the Dish receiver? I'm using Airplay on the TV and wonder if this is the best I can expect or if here is anything else I can do to improve video quality. Thanks for your help.

Streaming video, especially HD video over the Internet requires sufficient bandwidth for video quality. That would mean, in addition to having the proper bandwidth on each of the local networks in MI & CO, the Internet connection between locations must also be able to handle the streaming traffic.
Most consumer-grade Internet service offers far better download speeds than upload. However both will be required in this case.

Still bad video quality

even is catalyst cs 5.5 two of my problems do not resolve.
bad video quality in fullscreen. i have some videos for offline view (768x576 @ 2600 kbps) but still fullscreen view is messed up, all blocky, not proper video interpolation. in vlc or any other player the flv file looks fine!
the videos also have a 4:3 ratio and show white borders in fullscreen on a 16:9 screen in letterbox, how can make the borders black?
is there any solution?

Hi
as example
Creating a PAL movie in iMovie HD 6 then import this into a NTSC iDVD project
• Works but with a losy quality
I do use JESDeinterlacer3.2.2 and let this do the PAL to NTSC conversion
Now burned as an NTSC iDVD project
• Best result possibly without buying PRO-applications for $$$$$$$
This way should work the other way around too.
Most modern PAL DVD-players can playback NTSC (if TV is old in Bl/W)
Most modern NTSC DVD-players can't playback PAL
If playbacked on a Mac PAL or NTSC is of no interest.

Help-Very bad video/audio delay with China user

I am using iChat with snow leopard in U.S. and my son is using iChat from China with leopard. We can bring up iChat. He can see and hear me clearly, but there is about a 10 second delay. I can see him but the video is very pixelated, blurry, and slow. His voice is delayed and somewhat garbled.
He has wireless internet in China, but I'm wondering if there's something we can do to improve the video/audio. We are both fairly new to the Mac, so any help is appreciated.
Thanks for the help!!

CCME : how to improve the video quality on VideoOverIP

Hi,
I'm testing Video OVer IP between a CCM and a CCME.
Whe the call is on, the video quality are different :
from the CCM, it is very good
but from the CCME, the quality is less good.
So how can I do to improve this quality.
Best regards

You can improve the video quality on VideoOverIP with QoS. The primary goal of Quality of Service (QoS) is to make network service better and more predictable by providing dedicated bandwidth, controlled jitter and latency, and improved loss characteristics. QoS achieves these goals by providing tools for managing network congestion, shaping network traffic, using expensive wide-area links more efficiently, and setting traffic policies across the network.

Bad Video in FCP Canvas Window. Normal?

When I am scrubbing through the Canvas Window, I am get lots of distorted video. I posted a couple of screen captures to my Mobile Me gallery as examples.
http://gallery.me.com/jay.sims#100398
I am running a 27" Core i5 with 8 GB of RAM and 512 MB of video RAM.
I just recently upgraded to this current iMac from a '07 24" iMac. I did not have these issues with my old iMac, so now I am worried I may have a bad video card on my hands.
I have the most recent updates to FCP 7 installed.
Any ideas?

I have posted screen captures of my Sequence settings and clip properties in the gallery I linked to above.
I do not have exact answers yet for what is happening in the Viewer window or QuickTime Player. I tried scrubbing through a clip in the View window, but FCP crashed before I could see any results. I have not fully test QuickTime player yet.
I can add that this problem only seems to occur while scrubbing. Simply playing video in the Canvas window does not yield any bad results and everything looks fine.
Also, I moved all FCP folders and media to a different drive. That did not correct the issue.
And I have discovered that once the issues occurs I cannot render any video. Attempting to render video results in the message "Error! Out of memory.", which I assume is not a good sign.

How to maintain audio continuity with segments of bad video

Anyone have any editing tricks for keeping good audio footage when there are interspersed segments of poor quality video? For example, I have 10 min of contiguous audio that I don't want to disrupt. Halfway through, however, I moved to camera to a different perspective and the time during the movement is nauseating footage of the floor. Obviously the pros using multiple cameras could simply splice in footage from another camera for the time period during which the main camera had bad video footage. I'm only using one camera, however. Any tricks for keeping the audio intact, but 'hiding' segments of bad video? fade in and out of a photograph/still image? maybe I need a good reference for video editing. thanks in advance for any/all thoughts.

Always shoot a bit of 'spare' footage at the beginning, and whenever there's an opportunity (..I know this is being wise after the event, but it may be of help for next time..) ..e.g; if it's a wedding, shoot guests arriving, or people sitting attentively, or bits of the building (..stained glass windows, etc..) ..or if it's a theatre or a play, ditto ..so you've got relevant, related bits which you can drop in during camera moves.
As Karsten and Beverly say, by using "Paste Over at Playhead" to insert extra material on top of the audio, you automatically keep the sync between picture and sound, because iMovie removes exactly the same length of original video as the length which you're "pasting in" to replace the bad footage ..thus keeping sync.
If you don't have "..a photograph/still image.." to drop in, you could always create a still from some of your video footage (put the Playhead where you want it, then use ShiftApple'S' to Create Still Frame), maybe soften it or crop it a bit so that it doesn't look exactly like a frame from the video, then do another couple of similar stills, dissolve between them, and then use that set of stills/dissolves to replace your bad footage.*
'Paste Over at Playhead' is the way to keep it in perfect sync without having to desperately calculate timings, etc..
*P.S: It's best to Export that sequence of stills-with-dissolves to QuickTime as 'Full Quality' so that it becomes one whole Clip, then re-import it, and that way you can position it exactly where you want it, without any of its separate components (stills, dissolves) coming apart, or being interpreted as individual elements.

Bad video/good audio--slideshow?

I took a video of my daughter's high school musical. The audio came out fine but the video isn't so good. I'd like to take some still photos that I have and merge them with the audio from the camera to make a slide show. Can anyone walk me through the process?

If what you want to do is have the video continue running but put photos over some of the bad video, follow these instructions from iMovie Help:
Inserting video clips or photos in a passage while maintaining running audio
You can paste a new video clip or photo over an existing clip while retaining the audio from the original clip. The video cuts away to a new picture, but you continue to hear the sound from the original clip.
To replace images in a clip while maintaining running audio:
Choose iMovie HD > Preferences, and then click General.
Select the "Extract audio when using Paste Over at Playhead" checkbox.
Select the video or photo that you want to insert.
Choose Edit > Cut or Copy.
Do one of the following:
To paste the entire video you selected in step 3, position the playhead at the first frame to be replaced. When you paste the clip, it will replace a portion of video equal to its length.
To paste over a specific segment of your movie, select the part of the video clip you want to paste over. (To learn more about selecting part of a video clip, see Related Topics below.)
If the video you're pasting is longer than the selected frame range, the excess video will not be pasted. If the video you're pasting is shorter than the selected frame range, the extra space will be filled with a color clip (or the still image, if you paste a still image).
Choose Advanced > "Paste Over at Playhead."
The audio track of the original video is retained and appears in audio track 1 of the timeline viewer.
This should give you a nice smooth movie with interspersed photos with the video.
Be patient, the extraction of the audio may take a while!
If you want to ENTIRELY replace the video and just keep the audio, you have a couple of methods.
1. Extract the audio from the entire movie. May take a while. Then, delete the video track, keeping the extracted audio track. Add your photos to the video track, adding transitions, adjusting the timing of the photos.
2. Share the audio as an AIFF file, create a slideshow in iPhoto and use the audio track as your music for the slideshow. Start by selecting 'Share' to QuickTime, then choose compress movie for 'Expert Settings.' Then 'Share' and when the next window (save exported file as) appears, go to the dropdown menu buttons. For Export: select 'Sound to AIFF' and for Use: 'Default Settings.'
Just the audio will be saved as an audio file.
Then, open a new iMovie project, choose timeline view, drag in the audio file, and add your photos. You will have to see what effect you want with transitions, timing of the photos, Ken Burns effects, etc.
If you want to be very professional and actually sync the audio to the photos in some systematic way, have a look at Karl Petersen's thorough explanation here
Good luck....sorry that the original video was not good :_(

Improving iChat Video Quality

Is there anything one can do to improve the video quality on iChat. The image looks great on Yahoo Messenger and Skype but it's really fuzzy, blurry, distorted, pixelated when using iChat.

Hi
First have you set the Quicktime streaming setting, goto sys prefs/quicktime/streaming/streaming speed, set to 1.5mbps
In ichats prefs click on video and change bandwidth limit to 500.
Restart iChat.

How can I improve slow video streaming?

I just got a new Asus UX303LN - i7, 12 gb, quad HD screen, etc. I'm running Windows 8.1 and Firefox 32.0.1.
Part of the issue I'm having is due to connection speed, which is independent of Firefox. But I disabled hardware acceleration firefox, and saw some improvement in video streaming (less choppiness). On my old computer, for some sites, particularly Dailyshow.com and colbernation.com, the stream would automatically downgrade to lower resolution if my connection was an issue. I'm finding that the stream does not degrade and it insists on streaming a choppy HD feed. Also, on these sites, the controls that usually pop up for full screen are not there. Other sites are better but still I'm looking for suggestions for anything I can do in Firefox to boost performance or degrade the stream's resolution when my connection is sub-par. I've also tried the laptop's power settings through Windows. Thank you.

disabling WebGL had a significant positive effect. The video quality is somewhat less but the choppiness is gone. I'm confused though - is it possible to have the best of both worlds - use my hardware to get fast and not-choppy performance?

Bad Video Ram? N560GTX-Ti Twin Frozr II

I noticed that in games, and in youtube videos, there would be pixellated patches that were off-color. I noticed some that were tinted red, and others tinted yellow. So I opened up GIMP's color picker and indeed there were two off-color lines of improperly tinted colors forming an x in the middle of the color picker. Because this appears to be a purely display problem, I couldn't take a screenshot of the problem, so I took a photograph of my monitor.
http://img155.imageshack.us/img155/694/picture001vn.jpg
The refresh distortion makes it a bit hard to see, but there's definitely an "x" shaped distortion running through the center.
Now that I'm halfway through writing this response, however, the problem seems to have spontaneously fixed itself. It's been only a few hours after I first noticed it. I'm wondering, could it be related to some other problems I've been having? I've been having issues on and off for the past few months. For example, after reading this article, I've seen all of the problems illustrated in the first three images at least once. I've seen much fewer problems after getting brand new drivers a few months back, but I've still had problems here and there. Usually it'll work fine, but occasionally the screen will freeze for two seconds during a game, then all the textures in the game will shuffle themselves around. At this point, spiking sometimes appears, and the problems will persist until I either restart or the computer crashes.
This card is only a few months old. Am I right in thinking the video ram is defective?

Can you show how it should look to compare it to yours?
Also it could be some kind of monitor issue, have you tried with other one?
I apologize that imageshack seems to have drastically lowered the quality of my images. It does seem very hard to distinguish between what's refresh distortion from taking a photo of a computer, what's jpeg artifacts, and what's the actual issue, but I assure you the problem is still visible.
Here's how it should look
http://img148.imageshack.us/img148/3350/picture003wt.jpg
Here's a copy of the original picture with the 'x' shaped lines emphasized. I have drawn arrows pointing to the problem, which manifests as two straight diagonal lines forming an 'x' across the color picker.
http://img42.imageshack.us/img42/3558/linesx.jpg
I'll point out that this problem appeared to be linked to specific colors. I noticed it in both 2D images and 3D games. The photo is just there to show that with all the available colors displayed on a color picker, the problem manifested itself in a distinct pattern relative to some colors.
And no, I haven't tried it with another monitor. Like I said, the problem spontaneously fixed itself halfway through writing the original post so I couldn't test it. I'm posting here mainly because it's the third video problem I've seen so far that's been listed in this article as a symptom of bad video ram. Of course it's hard to isolate these problems because they seem to come and go. Occasionally it'll get really bad, then after a restart it'll be fine for a week or two.

Also check cables and connections, especially if you use VGA - digital cabling shouldn't be impacted.
I'm using a DVI connector, so no VGA.

Bad video quality of final product when viewing on computer in full screen

It looks like a picture does when you blow it up and it's a low quality image. Everything I'm reading says the problem would be with the video capture...but I have the same bad quality when I'm viewing the menu! Around all the text on the menu, it's fuzzy and same with my video on the menu. So are my video clips in the movie itself.
I have tried playing it on Windows Media Player, the apple DVD program, and WinDVD and I get the same problem when I view it on full screen.
I assume my family will mostly be playing it on a TV. Do you think it will play properly or worse on a TV? I don't actually have a DVD player myself to test it out. Any suggestions on why this could be happening?
Thanks!

when I started using iDVD, one of the hardest adjustments for me to make was video quality on TV screen vs on computer screen. (I am used to satellite to S-Video TV and HD screens on my computer.)
My camera it a miniDV, and playback via SVideo to an Svideo TV screen is awesome.
I was sorely disappointed when I played the same tape back on the computer. It was grainy/fuzzy, etc. Same with the DVD I made.
But when I played the DVD back on the TV, the image quality was the same as when I connected the camera to the TV - crisp, sharp, video and text.
I've since burned numerous DVDs, and the result is always the same - blah on the computer, sharp on the TV.
As someone else in this thread stated, the average TV is low-res compared to the computer screen.
If I recall the spec correctly, standard NTSC is 240 line, SVideo is up to 500 line. HD is 720 line and higher...ergo an NTSC source is roughly 1/2 the resolution of the typical CPU screen, or 1/3 the resolution of low end HD screens. So yes, NTSC output on your computer screen will always be fuzzy compared to your TV screen.
I think you will likely be very pleased with the DVD when you playback on your TV.

Bad video...columns of small white dots, pixelation

Can anyone help me...i've had the apple tv for some time and now i get inconsistent video quality. Just started several months ago. white dot columns, pixilation are the problems, any suggestions?

I have the same problem with mine starting tonight, and I'm pretty sure the internal video card is going bad.
I bought mine years ago during the first few days after the ATV was released. It was running OS 3.02 as of tonight. When I "restore" it installs version 1.0, but the "dots or lines in video problem" is still seen in the menus. And after the restore it started to lock up randomly, with nothing on it, just by going through the menus.
I'm leaving it unplugged to see if the problem is over-heating, but it's not any hotter than usual.

Improving P2P Video Chat in Bandwidth limited Situations

I did a little work this past week to improve our performance, and automatically scale back our bandwidth usage when we were in low bandwidth situations. Primarily we were trying to combat choppy audio, video delay, and low video framerate. It turned into more work than I expected.
Anyway I thought I'd share our approach in hopes that other P2P video chat people here will do the same and we can all learn how to make a LCCS P2P video chat the best it can be.
Let me know what you think, if I suck, etc etc.
Here's a link to a pdf about it: http://www.familyhealthnetwork.com/Improving_LCCS_P2P_Video_Chat_In_Bandwidth_Limited_Situ ations.pdf

Hi Eric,
Sorry for not responding earlier (we've been running around w/ hair on
fire... You'll all see why shortly...), but this is really amazing! Thanks a
ton for putting this together and sharing it with us.
Any technical reason to use XMPP as the message relay for the STFU? Seems
like a simple transient message via LCCS could work here.
I'd love to discuss this a little more deeply once the dust settles on our
side.
