Will sending video from my TV through my vcr/dvd player get rid of lines?

[Darkstraw]

Someone told me this might work. It would be much easyer than me having to get rid of them after they are already there. If anyone knows of a way to remove scan lines from video without doing anything else i would love to know. Currently i cant find an encoder/compresser that will remove the lines AND not dsynch the audio except for the software that came with my card (i bought the card for 10 dollars new so you can guess how good that software works... it somehow works but its got few options)

Not sure what you mean by 'scan lines'? Can you post a screen shot? If they are interlace lines, then a TV will show the video without them. Or a software player that understands interlace will also.

When i capture with my capture card from my TVat certain resolutions, it has interlace lines.

OK my problem is that i want to capture higher than 320x240 so youtube will show the "higher quality version" of my files when i upload them.
problem is that when i do this interlace lines show up, and while encoding software gets rid of the lines for the most part, it still shows alittle bit.
From what i understand dvd players and the like dont show these lines because it fixes it before the signal gets to my capture card. SO, shouldent i be able to hook up a dvd/vcr player up to my TV, then hook the capture card up to my dvd/vcr player (effectivly having the video go through that before getting to my computer/capture card, and get rid of the lines before they get to my card?

Interlace lines are normal for a MPEG video when you view it on a software player that doesn't properly handle interlace. VLC and others can display it properly, as do many other software players. A TV doesn't show interlace artifacts with MPEGs as interlace is the native format. Some DVD players can output interlaced as progressive, if the display device can accept that. 320 X 240 MPEG is a non-interlaced format. 720 X 480 MPEG is interlaced.

If you are converting to a AVI or other formats that are commonly not interlaced, just deinterlace it first. It sounds like you just need a better deinterlace filter or conversion program. Try AutoGK or even VirtualDub Mod as it has quite a few deinterlace and other filters available. What format do you plan to send to YouTube?

Well my capture card captures raw AVI best it seems. I use virtualdub to capture. Ive been capturing raw lossless video with virtualdub and then ive been encoding it with mpeg4 cause i heard it was best. I want to have good quality files on youtube, and read this, which i will paste below.

In March 2008, YouTube launched a feature which allowed some of its videos to be viewed in 'High Quality' format. This format offers the possibility of better video definition (480x360 pixels instead of the standard 320x240 pixels) for any video uploaded after this date. YouTube decides which videos are capable of this improved quality based on the standard of the original upload. Users can choose "always show me higher quality when available" on their video quality settings page (http://youtube.com/video_quality_settings) in their account pages to switch automatically to the better quality.

YouTube's high quality videos are available in two versions, both of which have a maximum picture size of 480 x 360 pixels (http://en.wikipedia.org/wiki/Pixel). By adding &fmt=6 to the web address of a video, it is played using the H.263 (http://en.wikipedia.org/wiki/H.263) codec with mono (http://en.wikipedia.org/wiki/Monaural) sound, and by adding &fmt=18, it is played using the H.264/MPEG-4 AVC (http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC) codec with stereo (http://en.wikipedia.org/wiki/Stereophonic) AAC (http://en.wikipedia.org/wiki/Advanced_Audio_Coding) sound.[42] (http://en.wikipedia.org/wiki/YouTube#cite_note-41)

Im not sure but wouldent it be best if i uploaded my files to youtube in mpeg4 for that reason? Ive been capturing in virtualdub and encoding in meGUI. Megui encodes and gets rid of most of the interlace lines (almost all) but its still noticeable, i can live with the lines but if there was a solution to get rid of it i would like to do it. Im capturing video from my wii, i play a fighting game and if you look at the stage its off (from the interlacing) but thats it. the rest of it is deinterlaced properly. I would capture in a resolution thats not interlaced but then youtube wouldent use the high quality version. the interlacing isent that big a deal as ive stated, but if i could get it perfect i might as well. if i cant then its no big deal. Heck i dont even know if ill be able to notice the stage looking differnt on youtube or not.

Not much experience with YouTube, but there are quite a few posts about it on our site.

You don't see interlace comb artifacts on an interlaced TV because the TV shows only one field at a time. You never see an entire frame on an interlaced TV. You don't see comb artifacts on progressive TVs because they deinterlace the signal as they receive and display it.

If you want to upload higher resolutions to YouTube you will have to deinterlace first. The best solution is to get a camera that shoots progressive.
