Really really small lines in DVD playback
Hi pplz again,
Ive made a 1280×720 video adn rendered to mpg2 with dvd pal architect widecreen sream.
In both PC and tv playback im getting tiny lines during horizontal camera movement… is this interlacing issue?
the project is in upper first im sure, as is the render, and im burning to disc with roxio and using interlaced… however im still getting this issue.
Video is from a 1440×1080 sony HDR footage (25fps PAL)
What else is there to try/play around with to help me remove the lines.. They are very small (only about a pixel high) however they remove lots of quality from a nice wedding video i made!! 🙁 thanks for any help

Without seeing what you are describing, I strongly suspect that you are seeing compression artifacts.

Found an example. It shows the lines on grooms jacket. This is the best example i could get easily, but it always occurs when there is large horizontal panning by mehttps://i785.photobucket.com/albums/yy138/gambi3r/weirdlines.jpg

These are interlace lines, and might be caused by the media player not correctly handling your video. However, you might have accidentally used the wrongs settings and made a video that contains the interlace artifacts.
Try playing the DVD in a normal hardware DVD player and TV. If you still see these lines then you need to re-render your video with the correct settings.
You should be rendering from your 1440×1080 HDV project directly to the DVD format using the DVD Architect Video Stream preset under the Mainconcept MPEG2 render format in Vegas. Don’t do an intermediate 1280×720 render because that just takes extra time and the quality suffers.

What kind of settings should i check for? Interlacing etc?Try playing the DVD in a normal hardware DVD player and TV. If you still see these lines then you need to re-render your video with the correct settings.
I do get them on a tv with normal dvd player… but what are the correct settings i should try using?You should be rendering from your 1440×1080 HDV project directly to the DVD format using the DVD Architect Video Stream preset under the Mainconcept MPEG2 render format in Vegas.

Im going straight from my project which is 1280×720 (not 1440×1080) to the above mentioned mpg2 format. SHould i try changing my project to 1440 then retrying? Im not rendering twice, its just my project is not 1440×1080.. perhaps thats the issue? -
You should normally set your project settings to match the source video (especially if you plan to render to multiple formats), or the desired output format (such as NTSC DV widescreen) if you have different input formats.
Try setting your project to match the source video. In the Project Properties panel, there’s a little film-strip icon called Match Media Settings. Click that and pick one of your source video files to use its format as the project format. You *may* get some slight change of cropping or positioning of events because you’re changing the frame size of the project.
Then try a re-render of a short segment to test. You shouldn’t have to touch interlace settings if you use the render presets when rendering to MPEG2 for DVD.
