video quality problem
Hello there.
i am interested in creating short films with digital video.I have to say that i am not very familiar with the technical part of the post-production process.Anyway.Im am using sony pd-170 camcorder.When i playback my footage on the TV the quality is very good,but when i load the video on premier,edit it,render it and then export it as a video file on hard drive the quality is not good.The video appears too grainy and it also has noticeable square pixels.What is the problem?
Info:
PC:2.4Ghz,WindowsXP,1GB RAM,300GB hard drive space.
Via Firewire capture card:a cheap one about 30euros cost.
Software:premier pro7.0
Export configuration(as they appear):
General:Microsoft DV AVI
Video:Compressor:DV PAL
Pixel aspect ratio:D1/DV PAL(1.067)
Keyframe and rendering:Fields:Lower field first.optimize stills.
Programs to watch the videos:windows media player,cyberlink PowerDVD -

i see two possible reasons: 1. you used a different codec when you rendered your project to a file. You should render with the same codec–microsoft DV pal. 2. or, you think the quality is poor because you are previewing it in your computer monitor and is watching it in full screen. Preview your video via firewire out to TV (you need something like ADVC 100 to do that.
hope that helps

thank you for your reply.
1)I didn’t understand what you meant about the codecs.I use the ones i mention before.
2)I thought that a coputer screen has better quality than a TV monitor.
Somethin extra that i haven’t mentiond in my previous post:my footage often has horizonal noticeable lines.
Thanks in advance -
1. Digital Video is really just an editing medium. For local playback try Windows Media Video 9 at about 2mbps or even Mpeg 2 at about 8 mbps.
2. You are seeing fields…they dont display well on a PC monitor. For local playback choose to deintelace your export. -
You have interlace problems in your video. Your computer screen does not have a “better quality” than your TV monitor. A computer screen is non-interlaced whereas TV is interlaced (unless ofcourse you have an LCD TV. If your final output is meant for computer viewing, then you should use a computer to monitor your video. If not–you should monitor using a TV–or a calibrated field monitor if you have access to one.
