> Someone else has advised me to render as a progressive to an avi using the CineForm HD codec V2.5, use this as an intermediary and then open a new 50i upper field project and render out as interlaced. What do you think?
I think that’s as bad as what you originally did because it is deinterlacing to render progressive and then re-interlacing to go back to a 50i project. You want to avoid all of these conversions. Just use what’s on the tape in the format it exists on the tape.
The video from the camera tape is interlaced. Printing back to tape is interlaced. If you want the fields to be the same, don’t ever convert them to progressive. If in the final render, after you have the color grading complete you want to print the final project as progressive, then and only then I would render to a progressive MPEG2 file to place on DVD or Blu-ray.

> Why cant we just render an original Cinform avi file to 720×480 and put it directly into DVD architect?
I just assumed you wanted to edit it. You could certainly drop the CineForm file directly into DVD Architect and make a DVD. It won’t make any difference in quality since DVD Architect will have to render it to MPEG2 anyway. So whether you render in Vegas or render in DVD Architect you still need to go through the same render step.

You have to navigate into each clip and set the end action to point to the next clip. Just double-click the first clip, select the End Action property, and change the Destination from Most recent menu to whatever the next clip is in the sequence you want. You have to do this for every clip.

It looks like the aspect ratio of your video does not match the project. There are two ways to correct this. Set the project to match the video or crop the video to match the project. To match the video to the project, open Pan/Crop on the video event and right-click on the window that pops up and select Match Output Aspect. If that cuts out too much of your video then you need to undo that and set your project properties to match the dimensions of your video. The easiest way to do this to open the project properties (Alt+Enter) and then press the Match Media Settings folder (upper right) and select the media file to match to.

> The template is set at HDV 1080-50i, progressive, and the field order is set to progressive
I don’t own a Sony HVR-V1P but I think your problem is that the Sony HVR-V1P is HDV and HDV only supports 50i (PAL interlaced). So while the camera may have captured 25p from the CMOS sensor, it had to lay it down on a 50i tape. The clips that you captured should have had their properties set to interlaced by default. I have a HVR-Z1U and when I shoot Cineframe24 the video is really 29.976 interlaced. I know the V1 is different but HDV is HDV. Like I said, I don’t have a V1 but in looking at the specs it is definitely recording 50i to tape.
I’m thinking that you should not have changed the project properties to progressive unless you were going to output progressive (which you did not since you printed back to a 50i tape). You should have left the default template for HDV 1080-50i. It probably deinterlaced and then re-interlaced and caused the problem you are seeing. I would go back and change the project to the default 1080-50i template and print to tape again and see if that fixes things. (worth a try since no V1 owners have responded to this post)

I don’t even think AVCHD UpShift will help because it turns AVCHD into HDV which still requires a minimum 2.8GHz processor. Not even GearShift will help because it will still take forever to create the DV proxies. All of these solutions are for people who don’t want to go dual core or quad core yet but this person doesn’t even have a single core capable of the job. He really needs a new PC for working with HD video.

Yes. AVCHD is challenging to render on the most powerful computers. If you look at the system requirements for Sony Vegas you’ll see it says “(2.8 GHz recommended for HDV and AVCHD)“. And they’re not kidding. A 1.59GHz processor isn’t anywhere near enough power.

I’m not Douglas although I do work with him at VASST. 😉
Since you have CineForm 24p source and your desire is to make a DVD I would create a project using the HDV 1080-24p (1440×1080 23.976 fps) template. Drop your CineForm 24p footage on the timeline and edit as you normally would. When you are ready to render, use the DVD Architect 24p NTSC Widescreen video stream template and render the audio separately as AC3. This will give you the best quality.
It is important to note that HDV widescreen and DV widescreen are slightly different. Your DV widescreen will have slight pillarboxes on the sides unless you use the Stretch video to fill output frame size (do not letterbox) option. This will stretch your video slightly so it’s up to you whether you want to use this or not.

> but it would be nice if there was a way to accomplish that task. A script maybe?…
Absolutely. You could use VASST Ultimate S Pro to fix this in two clicks. First you would select one of the events that uses a MOV file and then on the Editing Tools tab use Select Same Source Type to select ALL of the MOV files in your project. Then just go to the Video Effects tab and use Video Event Properties to change all of the alpha channels at once. I’m sure Excalibur has something similar.

Yea I just tried it and it doesn’t keep the alpha channel setting. Not sure why this isn’t working but I’m seeing the same thing with MOV files that I know have an alpha channel. Very strange.
