HDV to V9; how to adjust clips

Shine wrote on 11/20/2009, 2:27 AM
Each clip imported from my HDVcamera is a little bit too long, containing a few frames from the next clip. I have to adjust every clip in the trimmer or on the timeline in order to have smoothe transitions. No problem with a small project, but just now I have started working with a 90 mins project with loads of clips, and it gives me a lot of extra work.
Any of you guys working with DV tape having same problem?

No but it's pretty normal to have to trim each and every clip.
If you don't plan on doing that for some reason I'd suggest you capture with scene detection Off.

Hi,

Sorry to say, but this is a known bug that has been plaguing Vegas at least since the V7 version!!! SCS has done nothing to correct it - and that is a big shame!

You have 4 options:

- just continue to suffer and continue this editing - that causes lots of extra work (sometimes the only option)
- do NOT use the scene detection feature during capture (split scenes - if needed - on the timeline)
- use a 3rd party program for the capture (such as HDVSplit - but it too has some quirks)
- wait for SCS to fix this problem (that is not a viable option if you don't want to wait for eternity)

Anyhow, please raise a ticket with SCS, if you think that they should fix an advertized feature - to work as expected. They should be aware of how nasty this problem really is. More people complaining - better chance that they will fix it. I have been tearing hear and loosing my mind because this problem. I have many projects with a huge numer of separate clips (about 800) that I must re-arrange on the timeline, and additionally edit at the end because of this problem...I gave up hope that they ever will fix this... This does not very much increase the shininess of the "Pro" word after Vegas ... Just on the contrary, the Pro feeling gets a hit...

Christian

EDIT: For those of you that are capable of writing scripts:

There IS still a "social call" for a script that would cut the last 6 frames of every selected clip on the timeline.... At least for me such a script would save counltess of editing hours, in every HDV project....

Hi again,

Ok, so I'll just have to live with it, but I will for sure make a complaint to SCS about it.
Even in Studio 14, and all earlier versions, this works perfectly. Also in Liquid Edition.
What might be the problem for SCS here?

Thanks anyway.

This was discussed in 2006 here:

Read down the thread and you'll see that Jonask wrote a script to trim frames from the ends of clips to deal with it. You can adjust the number of frames that it trims. Direct link is here:

http://web.comhem.se/~u82707197/vegas/Trim_Captured_Clips_v1.0.zip

I use HDVsplit and I'm very happy with it. I recommend not using the preview as this has made it unstable for me. It's rock solid for me without the preview. (Sony Z1 camera, Windows XP)

Even with HDVsplit I still used this script on every single clip that I captured because of a bug in Sony's HDV reader (codec) that repeated the final frame. But since Sony's new HDV reader (introduced in about 8.0b/8.0c) I don't need to use it at all.

With HDV?

Studio could handle HDV from version 10 or 11 I think. I never had a similar problem there. In Liquid Edition it runs perfectly.

To Nick;

I remeber I also had the problem with the repeated final frame. It really made a mess with all transitions.

Thanx Nick a zillion for the link to the script!!! I wonder how I have missed that one. Will try it this evening :)

Great forum and great people - I have got so much help from many of you!

rgrds,

Christian

Don't forget to go into the script itself and edit the number of frames you need to trim. It seems the number varies depending on your setup.

Does this zip file automatically put it in the script folder or do you have to do that manually?

I think the NLEs that you're referring to are native mpeg-2 editors.

The problem really begins with the nature of HDV. At the point of a scene break it's very likely that what's on the tape is not enough data to build a complete frame. Not to say that the problem cannot be dealt with but it's not a trivial problem and the solution can create other issues.

Just recenlty and by mistake I captured a HDV tape with scene detection On. I knew something was wrong as shortly after the tape was rolling. I monitor the A/V output from the VCR and my monitor was showing regular breaks in vision and sound. Needless to say by the end of the tape I had over 100 clips on the HDD and as expected I had glitches in the head and tail of every clip. I sucked it in and went back and recaptured the tape without scene detection on.

To correct what's causing you grief then the capture software needs to do one of the following:

1) Make the scene break at the nearest I frame. You probably wouldn't like this option as you'd still need to trim frames and/or you'd loose frames.

2) Buffer the data and rebuild valid GOPs. That means more CPU load during capture which could lead to dropped frames on underpowered systems.

3) Offload some of the issues from 2) to dedicated hardware. This also opens up the option to trancode to an intermediate codec on the fly.


I don't know if SCS will ever address this issue. It's been around for a long time, as long as we've had to handle HDV. What they should do is make a statement about their intent going forward. If it's an intractible issue for them they should say so. If it's an issue better dealt with by a 3rd party solution they should do a deal with the 3rd party to put the solution in the Vegas box or at the very least formally recognise the 3rd party solution.

Terry you have to copy the .cs file over manually to your script folder.

Of course, this is not the end of the world, but it is strange that SCS do not solve this for their users. HDV is the same whatever software you edit with, and other software handle this with ease. Even Studio, which is regarded as a much simpler software than Vegas9. Import the video with scene detection, and all the clips are automatically sent to the timeline.
