Problem capturing with Media Express and Premiere

[federomano]

Hi, i have a Retina Macbook Pro with 16gb of ram and a SSD disk
Im trying to capture with Intensity Shuttle for Thunderbolt and Media Express or Premiere

Its strange that this happens with both softwares



I tried different uncompressed and compressed encoding options
It doesnt happen all the time, depends on the video and the moment, it happens (i think) randomly

Can you help me please?

Thanks

nothing? thanks

It's not that nobody wants to help, but you've got a few strikes against you here.

1) There aren't many members using a similar setup.

2) We really don't know what we're looking at -- an animated GIF of a capture? of a problem athat always happens at that part of the video. A problem that happened at that part of the video at that moment, that one time only and you happened to film it off the screen? A simulation?

What we can say, since it's happening in 2 different NLEs you can probably rule those out as the problem. It looks like a frame is being retained in some memory and then decaying (in the intensity shuttle?) but whether it's being caused by bad fames, insuffuceint voltage or a faulty unit -- there's just not enough to go on.

Ok thanks for the comment, im not very good explaining myself and my english is not the best.
Its like one of the two fields holds while the other continues capturing ok. It happens for a few milliseconds and then the frozen field "pairs" the ok field and both continue the capture. This happens several times and most of the times happens when there are magnetic or dirt analog signal. I have a TBC (AVT 8710) so its really strange.
I created a gif so you could see the effect because it is very difficult for me to describe it, but maybe with this info i can contribute a little more.
Thanks!

That could very well be a TBC compensating for a poor analog signal. (Two items you hadn't mentioned before.) I actually don't see any internal motion in your GIF, is that the whole frame? What's your source?

[federomano]

The frame is cutted so you could focus on the "frozen-frame" issue, but theres noise on top and on bottom of the image. My source in this case is a VCR with VHS cassette, but this happens also when i use other sources like a Sharp Video 8 camera. What do you mean with internal motion? Thanks

[smrpix]

I mean none of the people within the frame are moving. It looks like a still. And yes, if this is a tbc issue, different types of edge artifacts are diagnostic.

It is an actual footage of the video, but here's a more complete example.

As you can see, when i open the video in quicktime, it shows the type of errors i talk about, but when i open the video in media express or premiere, the video freezes completely (not just one field but both, or maybe its deinterlacing ¿?)

Here's the good news, your problem has nothing to do with your macbook, your intensity shuttle, Media Express or Premiere. It looks to me like your TBC is doing the best it can under the circumstances. It has nothing to do with interlacing.

The problem is you're getting a really bad signal out of your VHS. All of that static is in the horizontal sync, the part of the frame that tells all the equipment where the frame is supposed to be. It may be tape damage, it may be VHS deck misalignment -- it's probably a little of both.

Try adjusting the tracking on your VHS deck and see if you can clear up the static.

If that doesn't work, create a new thread here with a title like, "Capturing from damaged VHS, what can I do?" That should attract the attention of the VHS capture gurus. Do not mention macbook, intensity, or media express in the title or you will be largely ignored again. (you can mention them in the body of your post.)

Your YouTube video is helpful, you can put that in your new thread.

Good Luck

That is amazingly helpfull smrpix, thank you a lot! ill continue looking for this and will post a new thread with the data you've given me. Thank you again!!
