I have been recording a video game series with this old Dazzle capture card. If you look at my video, you can see how the footage looks fuzzy.
I think it has something to do with my having to deinterlace it. I tried a couple different deinterlacing options, but the video just didn't look right.
The video's format is 1080p and I believe the game's native resolution is 480p. Can someone tell me how to fix this?

Not sure whether I can explain my question. I have a bunch of video material. Some of them are recorded videos from mobile phones. When people record the video on their phone, their produced video may contain more than just the recorded video I need. I need to detect and cut out the useless part. The useless part would be still while the part I need is changing and on the play.
I do not know whether there is any way for me to do it. I can write some code but I just do not know what libraries to use. Does it have something to do with OpenCV. Or is there a way to solve it with ffmpeg?
Hopefully someone can give me some ideas. Thanks a lot.
I need to create an application that captures a video from a webcam. Later on I need to load the video and be able to navigate around in the video freely.
When I use the videocap-demo that comes with the Sources of DSPack, the captured video is encoded in H264. When I navigate around in that video, the picture becomes blurry, with wrong colors and you can't recognize the picture. (I tried with VLC and Windows media player)
...playing the video works, but after jumping to any position in the video, it looks like this...
How can I tell DSPack to capture the video e.g. in the old MJPEG-format?
(I tried with old videos from my camera. In MJpeg the navigation seems to work flawless)
Thanks in advance, R.
I'm using AVMutableComposition and AVAssetExportSession to composite several discrete audio clips/files together into a single file, similarly to this post but there will be no "video" track. I'd like to give the track some visual appeal using a still image so that when the user plays the clip they don't just see a generic quicktime icon, ideally I'd replace the image with branding or something relevant to the audio content. How would I go about doing it and is there a way to do it without dramatically increasing file size(ie some way to have a really slow framerate or just something so its not generating 30 fps for what is non moving art.) Appreciate any help on this.
AVAssetWriter will allow you to create video from a still image. This question provides a great example of how to do so.
im working on Smart TV app for Samsung which should use youtube api to play videos. Embedded videos will work only when app resolution and yt player size are 960x540 or below,
if I set higher resolution (1280x720 or 1920x1080) player stucks, behaves really slow, and videos will buffer infinitely.
Has anyone succeeded in embedding yt videos with higher resolution player?
Thx in advance.
Video player work in FullHD resolution in fullscreen regardless of widget resolution.
If you have troubles with buffering, check your connection speed. Try play file from local network to check that selected resolution and codecs hadled well by TV.
recently i found this case. The youtube apps working great on 720p resolution if the video length is below 10min, but longer than that for example 30min the player will stuck just like as you said.
When changing the app resolution to 540p the youtube player working great again for all videos. I suppose the youtube is using progressive download on their player and Smart TV storage itself is not enough to prepare the long video storage space with 720p resolution rendering.
The conclusion is when using flash player/youtube in apps the best at using 540p app resolution.
Thx all for answering,
in the end I used different approach which showed like best solution.
I used 720p resolution, and youtube cue video functionality.
Basically i cued video, and on "videoCued" event i called "playVideo" method.
This allowed player to get ready and initialize before playing video.
I am trying to make a nice pretty video.
I have a AVI video from a GOPro video camera, and I hae some info I want to overlay on top of the video. Like Time, GPS, Speed, G-Force etc.
I got my raw data, and ActionScript coded it up into a Flash movie, but then worked out I have two issues.
Flash export to AVI is pretty crap, and basically does a screen capture.
The export to AVI cant be transparent or anything but spare/rectangle.
So, can anyone suggest a better way? Should I use something other than Flash to create my speedometer, that is more friendly for overlaying on a AVI?
This is the sort of thing I am trying to create.

I have a CSV of all my raw data, and am trying to find a way to overlay it and look as professional as that link above. I can make the dials in actionscript, but then exporting to AVI with a 'screen capture' type program, they look pretty crap. But on the other hand, inporting my HD video info Flash, and it becomes pretty crap quality, and still have the export issue at the end.
I'm not 100% clear on what you're trying to do.
If you mean that you want to put some info over a video using Flash, all you need to do is import your video onto the timeline on one layer and then place your information on a higher layer. If you want your video to play as a different shape, then you can simply apply a mask to the layer your video is sitting on.
If you throw in more directing information then I'll improve this answer for you :)
