According to this thread: http://forum.doom9.org/showthread.php?t=12683 DV is loosy vs Huffyuv that is lossless...!!!! Should I change to Huffyuv then? Does this mean DV has less quality then the other? I also heard DV has some pixel aspect ratio not being square issuee! what does this mean... And what about MJPEG codec is it good? And if I want Huffyuv I know I can't use DV Dazzle Bridge anymore can't it? what are my chances then?
If you are recording from a DV source (DV camera, DV VCR) then there's no reason to convert to any other format, since the video is already in DV format. CODECs are only lossy when converting. Of course DV isn't square... is your TV square? is your PC monitor square? I doubt it. There's no reason to make "square" video for a rectangular screen! There's no reason not to use DV. Since mose digital sources are DV anyway, converting will only lose quality. "Huffyuv" is not a codec I have ever heard of, and therefore I wouldn't trust it. Mabye it is good, but as far as I know, it's not. If you REALLY want a no-loss video format......don't compress your video at all.
This is one of the most hateful speech I have ever heard. Hey PAL I need to convert my videos to digital and I wanted something to give me the best in transfer... DV is great but if you capture straight on that format if not there are better options Huffyuv can probably give me exact match as my tape so then I can convert it to DVD and enjoy its full quality since 1 compression is better then 2. You seem to hate my innovative ideas.
I'm not "dissing" your innovation. You asked a question, and I tried to help by answering it. You asked if you should change to huffyuv. I said no, DV is fine. You asked why DV isn't square. I answered you. If you don't want the answers, don't ask the questions. --------- By the way, no CODEC will give you "an exact match to your tape". As I suggested, save your video as uncompressed avi instead of using a codec at all. If you're planning on converting to DVD, then this is the best way to go anyway (uncompressed or DV AVI) because DVD-video is another format entirely, which means converting again. Since this seems to be what you're doing, any "middle man" codec is undesirable, because it means converting multiple times, resulting in quality loss. Pointly, you can "innovate" all you want, and each time you convert it will deteriorate the quality of your original. If you wanted to goof off and "innovate", you don't need to ask how. Just don't expect your videos to look better than those produced by the simple, clean methods.
HuffYUV is definitely a better choice than DV if you're capturing from an analog source (assuming you have the hard drive space). As far as PAR (pixel aspect ratio), almost all resolutions require non-square pixels to display correctly on a TV. If you're dealing with a standard 4:3 picture (assuming an NTSC TV with 480 visible lines) you'd need a resolution of 640x480 (or 320x240) to use square pixels. Since these aren't DVD or even (S)VCD compliant resolutions you're going to end up with non-square pixels. The only time this is a problem is if you're watching it on a computer monitor using a player that doesn't adjust resolution to account for monitor pixels being square.
@Vurbal I don't get your last message... you say to convert my video using huffyu to 640x480 or 320x240 so that the resulting dvd will contain non-square pixels that will display fine on my tv? Also I want to know what good huffyu medium is available...
I know it's a confusing subject so I'll try again. If you want to display video on a computer monitor you should use 640x480 (480 x 4/3) for the resolution because computers use square pixels. If you want to playback on a TV you should use 720x480 because TV signals use the analog equivalent of non-square pixels. Also, if you're authoring to DVD the legal resolutions are 720x480, 704x480, 352x480, and 352x240. If you use 640x480 it's harder to author and your DVD player may or may not display it correctly (or at all). As far as HuffYUV goes, normally it's used for capturing in VirtualDub, but there are other programs that can use it as well. Unfortunately the only kind of capturing I ever do is through an MPEG encoder card so I haven't every used it for capturing, so I can't really help you much there.
