HDV playback to camera problem

psychodad · Post by **psychodad** » Wed Aug 23, 2006 3:53 pm

Hi all,

I encountered some strange problems while playing back a HDV video project to the camera for viewing it on a HD TV set. Since I have little experience with HDV editing I hope someone can help me.

I captured a video sequence from my camera (Sony HDR-FX1E). I edited the video and added some JPG pictures to it like I normally do with DV editing.

After finishing I wanted to see how it looks on a HD TV set, so I tried to record it back to the camera by selecting the transport stream template and created the M2T file.

The edited video starts with a title clip and 2 JPG images. I exported the M2T file to the camera and after the title clip and a few frames of the first JPG the camera shows a jerky video on the LCD screen during both the JPG images. After a few seconds of the first real captured video it seems to get normal again. But when I played the tape it misses all the frames during the jerky part and it shows a blue screen like nothing was recorded.

I defragmented the disk where the M2T file is on, but no difference.

I started a new project and copied the title clip and the 2 JPG images in it. When I preview this, I notice in the JPG images distortions like a damaged MPEG stream on TV. No idea what happens.

I created a transport stream from this and tried to record it back to the camera, but VE complains that it is not a valid transport stream. I am sure that I selected the right template. The same with a single JPG picture, taken from a digital photocamera.

I applied the latest patches and Update Pack from the Ulead site.

Can someone explain what happens??

Regards,

You didn't say if you're exporting interlaced or progressive, but presuming interlaced;

have you set the image clips 'Media source options' to apply the 'Anti-flicker' filter? If not do so and see if that helps. You access this dialog by right-clicking the clip and selecting Media source options from the context menu.

What this does is generate a second field for what is a progressive frame source, which is necessary in interlaced projects/exports.

Hi Terry, THX for replying.

As far as I'm aware the Sony isn't capable of progessive scan. The video is interlaced (I hope) and in the Media Source Options setting for the JPG images is "upper field first" selected. Flicker reduction is greyed out, so not selectable.

I rendered the video project to PAL-DVD and that works fine. No jerks or other strange things.

It could possibly be 'drop out', a problem with the tape which is more common than most of us hdv users would have hoped for. Have you tried transporting it to a different tape and playing it?

Yep, tried different tapes. No difference.

Also tried to change the quality of the MPEG from 50% to 100%.

The transport stream plays OK in the preview (when you open the file there is a button on the bottom to view it), so the transport stream should be OK.

It looks like it is related to the JPG pictures.

Did anyone try to make a movie with only JPG images and transport it back to the camera??

This is very similar to the problem I was experiencing:

That is exactly the problem I also experienced.

I did some extensive testing with all kinds of images and video with mixed results. But as soon as I opened the original video project with the problem, the problem remained.

I started a new project with exactly the same settings and imported the old project. I created a transport stream and recorded it back to the camera. This time I was able to record it to the camera WITHOUT PROBLEMS.

So it seemed that for some reason the video project was messed up. Every test with the original project gave me the same result: not able to record it.

During testing I noticed something else. I created a new test project and saw that deleted items (images, video, title clips) still appeared for a few frames in the rendered video. So VE isn't handling his cache properly.

I also tried to study the problem and my conclusion is that not the transport stream itself but the time codes are messed up and the camera is totally confused about this, resulting in the jerky movie. When I played back the faulty video on the camera I could see the time codes jump forward and back.

When I tried during one of the tests to make a video that only consisted of images, the created transport stream was not recognized as a valid transport stream. With every try I got "not a valid HDV transport stream". Only after adding a HDV video this problem disappeared.

My conclusion is that Ulead has to do some more work on their product.

My solution was similar to yours. I took the original project and broke it into two different projects which recorded correctly back to the camera.
