What size is the video frame size you are feeding compressor? Try sending compressor pre-sized 720×480 NTSC or 720×576 video clips before encoding the DVD. I wrote an article on transferring HD footage to DVD.

I really can’t tell what you are seeing, so I’m guessing. What you could be seeing is interlaced video lines which are jagged edges around anything that is moving in the video. These interlaced lines don’t appear on your television, but without them your video doesn’t retain the smooth motion that it originally had. Shoot me an email at support@dvdxdv.com. I’d love to take a look at it and further help you.

The computer monitor is designed for displaying colors in RGB while the television is calibrated for decoding Ycbcr video. They are different color spaces. Because you are working with interlaced video, you can’t see it on a computer monitor which is progressive. This becomes really important when dealing with field order problems.

MPEGStreamclip can’t maintain from DVD that contain significant frame drops on DVD. I’ve tested it against this and it doesn’t hold syn. 8 mm tape usually contains places where there is no valid video signal. Most DVD recorder drop frames on this situation, so what they do is they close out the GOP and wait until there is a valid video signal again. When a valid signal comes again, the DVD recorder puts out a new GOP picture with a significant time gap between them. The audio continues gong and that’s where MPEGStreamclip fails.

I would add a Timebase Corrector into your signal path from the 8mm tapes. I did by using my Sony VX2000 camcorder which has a built in TBC. There is all kinds of frame sync and drop out issues with these old tapes. You want to make your capture as clean as possible. I wouldn’t recommend using MPEGStreamclip for ripping DVDs from old 8mm tapes with frame drop outs. MPEGStreamclip can cause way too many sound sync issues. Free software isn’t free of problems.

Are you comparing the video on an external calibrated television connect to Final Cut Pro? This is the most important step for checking your video.
Because you are going from 1080i to 480i, you want to preview your footage in SD before you send it to Compressor. This is where you want to check your SD footage for problems. Try resizing your footage from 1080i to 480i to ProRes in Compressor and compare the two sets of footage side by side. They should look identical. The reason for creating an SD master of you footage is that you can fix the problems in it by using Compression markers or through blurring.

I wrote on how to use compression markers in this article. This should solve your problems.

Hi Michelle:
I just test a Sony Blu-ray burner (BWU-200S) with compressor yesterday. It works perfectly and doesn’t require Toast. This is an old drive, so the newer models should work just as well.

Are you exporting with the same video codec? Here’s my recommended workflow for transferring HD video to DVD.

I wrote an extensive and long article on which may help avoid these problems. It covers all aspects of getting HD video to DVD.
