VHS to DVD through ADVC 110 - Distortion at bottom of screen & more ?s

Hi everyone, I've searched through most of the discussions, which have helped a lot, but haven't had any luck finding a few answers. So here we go.

I am converting about 20 hrs of old home movies to dvd. I want to edit out a lot of the boring scenes so I plan on using iMovie 06. I bought an ADVC 110 to convert the analog to digital (I have been using RCA cables for video but it doesn't give the greatest video quality so I am going to try an S-video cable) and I run it into iMovie 06.

1-When I watch it in iMovie there is some distortion at the very bottom of the video and I'm not really sure what to do about it. I've heard of people having this problem before, but I'm not sure how they resolved it.

2-When I have clips in iMovie, where are those files saved on my computer?

3-I plan on making multiple dvds in iDVD. Is there any suggestions on the best way to do this. If I import in DV format and edit in DV format (in iMovie) how long, or how large, can I make the videos before I import them into iDVD so that they will fit on a DVD?

4-Do you have any other recommendations to make before I dive in?

Thanks everyone for your help!

First of all you have got the right equipment for the job - exactly the same as mine, and I had 60+ hours worth to convert!

Make sure that playback from the VHS is as good as it can get: clean the heads, and run the tapes on fast forward/rewind to remove any 'stickyness' before you start to copy.

Make sure you have enough spare capacity on your hard disk. DV streams run at 13GB per hour, and iMovie uses a lot of swap files. Don't even start this unless you a minimum of 25GB free!

If your VHS has an S-video output socket, well and good, as not many have. That only covers the video, so you will still need the RCA cables (white and red) for the audio.

The Canopus does of course have to be connected to your Mac by firewire.

1. That distortion is the timeline on the VHS video, which you never see on your TV. Once you have it all on DVD you probably won't see it on your TV either. iMovie reveals more of the actual video frame than a TV does.

2. Save the imported video in 5 minute clips, or your project file will bloat as you start editing. The clips (video) are stored within the iMovie project folder, the one in your Movies Folder with a star on it. When you come to editing SAVE THE PROJECT OFTEN - every two or three edits.

3. When you have finished editing (and try to keep each project to under 90 minutes, although 60 minutes will give the best quality) save the project and close iMovie. Open iDVD and start a new project. From the File menu in iDVD choose Import/Video. That opens the Movie Folder and you can select the project you want to work on.

When you have done what you want to do in iDVD (Theme, Titles, Chapters, Transitions etc) save the project, then 'save as Disk Image'. Why? Because rendering the video, particularly the audio, takes ages, and you only want to do it once. You can actually burn to a DVD from the disk image, so if you want more than one copy you don't have to wait for it to render each time. Also, you can play the disk image in DVD Player to check everything is OK and therefore not waste a DVD.

Post back with your next set of questions - if you are new to this there will be more!

Personal advice: experiment with a short 15-30 minute project, just to get the hang of it and build up a workflow you are comfortable with, then just go for it! 🙂

Klaus1 thanks for all of your advice. Here are some more questions for you, or for anyone.

It turns out that I don't have an S-video output from my VCR (its a VCR/DVD combo and the s-video is for the DVD only) so I am using RCA cables. However when I watch the clips in iMovie, the video isn't as good of quality as it is when it plays on the TV. Is there a setting I should adjust (on either the ADVC or in iMovie)? Or is it that my computer screen (which is way better than my TV) shows the imperfections of the VHS tape better than my old TV does?

So in my quest for better quality I have come across some more questions:
-I have my all my ADVC dip switches turned OFF except for 2 and 5. That is the default setting and I don't know if changing it will make the quality any better.
-What is pillarboxing and letterboxing? Right now iMovie is set to do those automatically.
-Also the format I am using for the project is DV format, is that the best format to be using?

Thanks again for your help, and if you have any suggestions for improving quality please let me know.

A bit of both. iMovie does not show the full quality (not does iDVD), this is to save CPU power, which is also why the quality may be seen as reducing when you enlarge the iMovie window. Video editing and especially rendering is about the most 'labour intensive' thing you can ask your Mac to do!

You will only see the final quality when you play the DVD on your TV.

As regards the dip switch settings, they are explained on pages 16-18 of the manual. It is important to set it for NTSC if you are in the USA, or PAL if you are in Europe.

As for 'automatic letterboxing and pillarboxing' (which changes the shape of the video), this box should NOT be ticked.

I like the convience of being able to see a visual timeline of the clips (in iMovie '08), so I was thinking about importing and editing the films in "08. However I also want to add chapter markers (which I believe is a feature only available in iMovie '06). So my question is, if I import the source material and edit the movie in '08 and then import the finished product into '06 to add chapter markers, will I lose video/audio quality in the transition from '08 to '06?

Thanks again, I really appreciate all your advice.

P.S. Also does the "keep your clips under 5 minutes or your iMovie project will bloat" rule apply to iMovie '08 also?
Could I just import like an hour of vhs at once, and then cut that clip into smaller clips as I edit? Or would this just kill iMovie?

Hello again! 🙂

If you are going use iMovie 6 I can see no reason to burden iMovie 8 with any part of the task! I would import and edit just using iMovie 6.

But no, you would not lose any quality.

Yes, whatever version of iMovie you use, the 'bloat factor' applies (non-destructive editing), so keep the clips to 5 minutes or less.

You can import a 60 minute lump and slice and dice it yourself, but what's the point?!
