Digital 8 compatibility with Edius 5

[Howard Asbridge]

I have a problem uploading Di8 material. Capturing it either as Canopus or 'DV AVI' the clips arrive in the bin OK. As soon as I play them, they 'corrupt' into pixellations all over the screen. Is there a particular codec I should be using to avoid this?

Hello Howard, Welcome

What GPU card are you using and are the drivers up to date ?
Help without any systems spec's is very difficult, please help us to help you !
What do you use to capture: hardware ?, Edius, ?, Neo ? what version ......................

Howard phone me and I will talk you through it and check what you are doing.

ive had the problem a couple of times, re capturing in a new project solved it

Thank you both for responding so quickly. I talked to David today and uploaded the same material again. This time is has stayed OK, although the clip I loaded yesterday remains corrupted. David and I can't figure out why it now works, but the problem seems to have been in the clip, not the system, as yesterday's still doesn't work when today's does.

Who knows what it will do tomorrow!

Having posted an update, I've just seen John's response. I have indeed created a new project as part of the process of uploading today, so that may be the reason it now works. I'll do the same again if the problem re-emerges. Thanks John

I have had this sort of coruption before on DV tape's who where recorded on a cam that had dirty heads and the actual file was not recorded properly, especially when played back on a different cam the source corruption did not improve at all.

The second type of problem I encounter every now and then are the consumer cams recording on a mini dvd disc, they ofter don't close the mpeg compressed file nicely, most of the time 1 or 2 frames are corrupt.

using Disc Capture and manually deleting the last frame or 2 on every clip seems to solve the problem.
Edius also is known to crash / freeze with those clips, then a analog capture of the material is the only solution.

Your problem might be tape and heads related, then again a system that is below spec can also behave erratic :)

[DigitalDave]

The Disc capture problem is a seperate issue so lets not throw that in here.

The crux of this problem was that this was E5 on NX that works OK with DVCam, so project/capture settings were all OK.

I have seen an instance where after a spot on the tape everything after it was corrupt on capture BUT DISPLAYED OK off tape. The Norm would be to drop a frame and split the capture. Recapturing from a few frames later fixed it.

I think that starting a new project is coincidence rather than a fix. Restarting the D8 source is more likely to flush the data line, either way it is sorted.......famous last words.......

Hello all

As David said 'famous last words'. I uploaded some more clips, all was going well. I thrashed each one, whizzing the cursor up and down it, cutting it into sections and so on. All fine. Added some more today and they were also fine, until after a while they corrupted in the same fashion as the initial lot.

I've tried opening a new project and putting new clips into that, but that made no difference. Likewise copying from Di8 to DVCAM; the DVCAM clip also failed. Lining that up with an earlier version, it's possible to see that the corruption follows exactly the same pattern in the same frame of both clips. That doesn't seem like a loose firewire or a dirty head, as presumably the patterns wouldn't be so consistent.

Unless anyone's got a solution, I think I either have to give up on this project or try a S-VHS transfer instead, which I'll do later this week.

Just to clarify, are you saying that some of the clips were OK and then they suddenly corrupted? If so I would suggest its a Hard Drive problem.

[Howard Asbridge]

All the clips get uploaded OK and can be put in the player window or on the timeline. When some of them are played/scrubbed/edited, they corrupt. Why would it be the hard drive, if not all the clips corrupt and only Di8 ones do it?

Try defragmenting your drive.

I would suspect because they are landing up in the middle of a "bad patch". Perhaps the hardware gurus can elaborate.

I cannot think of an instance where clips corrupt having previously been good that has not been attributable to Hard drive errors.

Brandon mentioned defrag- how much spare space? Can you try another drive?

[antonsvideo]

what happens after a clip corrupts? is it corrupt forever or does it come good after a reboot?

[David Clarke]

These are Di8 clips so coming in via firewire I assume. Did you use Edius to capture or DV capture?
How long are the clips?
I have had a problem where long DV clips, of an hour long, suddenly change into a weird pattern and they only way to cure it is to retart edius. Sometimes they work, sometimes they work for a bit and then go, sometimes they don't work. It only happens on long clips.
If I load the same clips into Premiere they work and carry on working.
The corruption is the entire picture changes to a series of large square and underneath it you can see the picture as if looking thorough a think glass window, but distorted.
My problem looks like what used to happen when PAL DV clips we being played as NTSC (a problem from many years ago). This may not be your problem but does it ring any bells?
