38358@http://www.videomaker.com/community/forums/ <p> I'm going to leave certain details out of my story for the sake of keeping it short.  Feel free to ask questions if you need me to fill something in.  I have videos on 8mm and Hi-8 tapes that a I import via firewire from a Digital 8 camcorder.  For those who don't know you can import analog video recorded on 8mm and Hi-8 with certain digital 8 cameras through firewire and it will automatically convert it to a DV file on your computer.  I'm in the US so my video is NTSC.  Now we know that NTSC interlaced video displays the lower field and then the upper field.  So if we numbered each field with field 1, field 2, field 3, field 4 and so on then the odd number would refer to the lower field and the even number to the upper field.  Field 1 and field 2 would combine to make frame 1.  So here's my problem.  Sometimes the video caputure seemed to combine the ending field of one scene with the beginning field of the next scene into one frame.  But this did not always happen when capturing the same piece of video.  I couldn't understand why sometimes I had this problem and sometimes I didn't, I decided to compare the problem clips with the none problem clips by analyzing each field in an editing program.  I figured out a way to isolate each field so that the field that I did not want to see was replaced with black.  If you want to know how I did this then ask.  Anyway, what I discovered was that the difference between the two videos was that the fields were some one reversed.  Lower field had been caputred as upper field and upper field capture as lower field.  So essentially the video should have been captured as Frame 1 [field 1(lower) field 2(upper)], Frame 2 [field 3(lower) field 4 (upper)] was actually captured as Frame 1[field 2(lower) field 3(upper)], Frame 2[field 4(lower), field 5(upper)].  It was like some how the first lower field was lost so the computer took the second upper field and recorded it as if it were the first lower field.  I hope this is making sense so far.  I don't always explains things well.</p> <p>Before anyone says that it might have to do with the settings in my capture program, I should remind you that no settings were change between the correct recording the and problem recordings.   In anycase, the first thing I want to know is if anyone has ever encountered this problem when try to capture 8mm tapes to a DV file by using a Digital 8 camcorder.  I'm fairly certain that I have accurately determined the nature of the problem but have to admit it sounds slightly weird that an upper field could be confused with a lower field and vice versa by a camcorder.</p> <p>I have noticed that this problem often occurs when I recorded the video with the following mistakes.  Sometimes you want review what you've recorded, but before the days of the "end search" button you tried to reposition the tape back the right place manually.  Of course what happens i that you don't necessarily position the tape at the right point and you get part of the tape with no signal on it.  I find that recordings that a preceded by this area of tape with no signal, I end up with the problem outlined above.</p> <p>But I think I've found a fix for files captured with this problem.  Adobe Premiere Pro has two functions called reverse field dominance and interlace consecutive frames.  I discovered that when you reverse field dominance and render the file then take the rendered file and interlace consecutive frames you fix the problem.  You just end up losing the first frame of the recording.</p> <p>Diagram: each number represents the field number.  Each column represents a frame and</p> <p>correct file</p> <p>2 4 6 </p> <p>1 3 5 </p> <p>Problem file (noticed how

40825@http://www.videomaker.com/community/forums/ <p>I have a old Sony DCR-TRV530 (Digital 8 camcorder).  I don't have the user manual.  Wanted to know how I can link up the camcorder to my computer and download either a Digitial 8 or Hi 8 tape to my hard drive.</p> <p>I have ULead Video Studio 11 software on my computer.  I use this with my Mini DV camcorder, which works okay when I hook up the camcorder to my computer via USB line.</p> <p>But when I hook up the Sony Digitial 8 camcorder via USB line, my computer doesn't seem to read/know the line is connected and the ULead software doesn't show the comcorder being connected to computer.</p> <p>Is there a special connector I need between Sony camcorder and computer and any software to read and record the Digital 8 and Hi 8 tapes to my hard drive.  Thanks.</p> http://www.videomaker.com/community/forums/topic/how-to-get-crisp-internet-video#post-35995 Mon, 14 Apr 2008 18:53:08 +0000 Gyent 35995@http://www.videomaker.com/community/forums/ <p>I was wondering how to get my videos to look crisp and clear after posting them on the web.  I use APP 1.5 to edit and a Sony dcr-trv530 (digital 8) cam.  After exporting and uploading to sites such as youtube the video appears very grainy, I have tried to play around with the frame size and aspect ratio but still get the same results.  I've used youtubes recommended settings (640x480) and still no difference.  A few of the videos in the short video contest used the sony dcr-trv730 cam (best senior video, best documentary, best comedy) which is a step above my camera and the video quality is worlds better so I don't think it is my ancient camera causing the problem.  Any suggestions or solutions would be much appreciated.  Thanks in advance</p> <p>~G</p> http://www.videomaker.com/community/forums/topic/help-exporting-in-app-15-for-internet-video#post-36158 Wed, 23 Apr 2008 15:58:30 +0000 Gyent

to websites they look very grainy and I believe I am using the highest quality settings.  A few of the videos in the most recent contest on videomaker.com used a camera a model up from mine and their videos are much clearer.  Any suggestions</p> <p>G</p>
