Thanks, Black. Trying that.

Question - I took my down-rendered DVD mpeg file, inserted it into the timeline and selected to let VS change my project settings to match the file added for smart render. Added scene cuts only for chapters (no multi-trim). When I go to create the DVD folders, the program renders the file again. I have 'do not convert mpeg compliant files' checked as well.

There is a slider for MPEG quality that was at 70% - I moved this to 100% thinking this would also cause the file to not need rendering.

Why is this rendering again? I thought smart render would make this go much quicker by not re-rendering compliant video which my whole video is since the project settings were automagically adjusted to match?

The idea is to do ALL your editing directly on the captured HDV. This forms your complete project. Then you can create identical video files of ANY quality: for example: 1440x1080 mpeg2, 1920x1080 Mpeg2, 1920x1080 Divx, or 720x480 (your downconverted video file), etc. directly from your original source video files.

Don't do "serial" editing, where you create a video file from an edited project, then put that back in the Edit timeline, re-edit that video file, etc. etc. Doing this repeatedly will eventually degrade your picture quality.

Bottom line: Don't put the rendered video file in the EDIT timeline.

Big light bulb just appeared over my head!

New project - empty timeline - share tab - create disc - added clip - added chapters - verified mpegs settings matched clip I added - clicked burn. Took a few minutes to build the chapters and what not and now it's burning! No renders.

Hoping the DVD plays with chapters properly in tact.

Thanks for the guidance. :)

I'm golden!

Just have a few frames that ended up on the wrong side of the chapter selection mark... think I chalk this up to the I-frames?

I need to learn to film a few seconds before and after the subject matter I am trying to capture so I don't need to cut contents for chapter markers. That and a lot less fast panning. :)

Success! Congratulations!!! :D

Now, your chapter problem is, I think, better handled in the Burn module, where, with a little practice you can place chapter entry points with single frame accuracy, using the vernier control. (i.e., Don't make any chapter edits in the Edit phase.)

If you truly want to subdivide a large project into disconnected segments, it is better to make a separate project (and separate video file) for each segment. Then, you can ADD VIDEO FILE in the Burn module for each segment, creating a main menu to the separate segments, with submenus to frame-accurate points within each segment.

BTW, you are right on about having to begin recording video with the HC3 and HC1 early because there is a variable time lag between the time you press the record button and the time recording actually starts. Ditto stopping. I keep my eye on the RECORD indicator in the Viewfinder/LCD for every shot.

This is actually how I placed the chapter marks. Jogged to the spot and then used the arrows to get the chapter mark on the frame division betwen the scenes. So the first frame of a scene appears as the thumbnail in the scene window at the bottom. I had read that MPEG has the limitation of 15 frame chunks where the chapter marks sit on either side when the burn process occurrs. Is this correct?

Good deal - thanks for the tip!

You are correct: in the DVD chapter entry selector, you can position the chapter entry point to to a GOP (I-frame). In the EDIT module you can cut with single-frame accuracy.

Thanks again for the help!

The learning curve on this was kinda steep... nice that the fog is now clearing. :P

Given I wanna try Womble - should I use MPEG Video Wizard DVD, MPEG Video Wizard?
MPEG2VCR is a simple "cut & splice" editor (similar to VideoReDo).

MPEG Video Wizard is a full featured MPEG video editor that can do crossfade transitions (and other fancy transitions), audio track editing, etc. (It does not have as many features as Video Studio.)

MPEG Video Wizard DVD adds DVD authoring. But, it needs 3rd-party software for DVD burning (i.e. Nero or Roxio), and it does not have the authoring cababilities of the Ulead roducts.
There is no assurance that these other editors can handle high definition video correctly and Womble has a terrible user interface.
I have not tried it with HD, and you may have to convert your files to SD first. The Womble user interface is a little "strange" (even stranger than the Video Studio interface). But, I no longer get sync problems, and my Ulead programs don't crash when I feed them MPEGs edited with Womble!

Okay - I have this thing sorted out once and for all regarding editing, sound sync with chapter markers etc... (woohoo!)

One last question on this regarding the basics...

Frame based down conversion is recommended injchunter's tutorial cept I was wondering if my video would look sharper on my progressive DVD player with component out to my HD TV if I carried the field based video from my camera capture to the DVD burn(vs a render into frame based)?

I prefer frame-based field order on my equipment because moving objects are sharper with the interlace distortion removed, while vertical resolution of non-moving objects are reduced slightly.

I do recommend that you try both interlaced and frame-based. Let your equipment decide which is better.

Burned another DVD after fixing my chapters by putting the markers at least two frames into the scene... no more frames sneaking into adjacent chapters. Think I have a finished product!

Did discover that my Denon DVD-1200 plays back the frame based DVD really nice - picture is great - very crisp when I'm not panning... Not sure if this is a limitation or not but it craps out roughly 1:20min into the video. The DVD player is a few years old so it might not be super friendly with DVD-DL media... it does play into the second layer but just kinda chokes towards the end. Any thoughts on a remedy for this? Strange that it plays 90% fine but pukes at the end.

PowerDVD plays back the whole DVD video just fine.

Panning quality is rough but that's inherent to HDV as I've read so I will adjust my shooting accordingly.

I will be making copies of the DVD for friends and family - might down convert this to fit on a single layer DVD. Sucks to sacrifice quality for compatibility but I guess it's the nature of the beast... I'm gonna hang on to a DL copy though. ;)

Well I played my DVD-DL disc on an older DVD player in our house and it plays perfectly... no drops or anything. Not sure what's up with my Denon DVD player - maybe it just doesn't like DVD-DL media.

Welcome to the quirky world of stand-alone DVD players! :lol: It is probably not that it has difficulty with DL discs per se. After all, you probably play commercial DVDs on it with no problem and the great majority of them are DL. But the fact remains that there are lot of brand name players out there, particularly older ones, which simply don't like home made DVDs, and that goes double :!: for DL ones... :wink: :wink:
