Is this an interlace issue?

That camera doesn’t shoot interlaced. It must be something else. Might be in how you converted it.

Download the Canon EOS log and transfer plugin, and use Log and Transfer. I have a link to it here:

Thanks for the tutorial Shane.

When I go to Log & Transfer and try to import the H264 files from the folder of that shoot, a warning window appears saying, “contains unsupported media or has an invalid directory structure. Please choose a folder whose directory structure matches supported media.”
In your tutorial you mention that when downloading the original SD card, everything on the card must be included. But because it was a while ago, I may have only downloaded selected files from only that shoot and not stuff that was not erased and recorded before.

You mention copying the folder. Would that still work?

[Enrico Lappano] “don’t know why I’m getting these lines, particularly on tree branches in forest scenes.”

Could you post a screenshot?

Are you able to set the Blackmagic card to monitor 29.97p rather than 59.94i?

I should add re “copying the folder” that the folder I’m transferring from is not on an extended HD, but already on my Mac Pro. So I’m not sure of the difference?

Can I fix the directory structure so it supports the media. The names of the files are the original H264 that were downloaded to the Canon Image Browser and they are in correct sequential order without any files missing from that day’s shoot.

I appreciate your feedback on this issue.

Hi Alex,

Here’s a screenshot example from my computer monitor. On the Sony Bravia the small branch horizontal lines are more distinct.

I’m using the Blackmagic Decklink HD Extreme card via HDMI. The video Playback setting is Blackmagic HD 1080i 59.94 – 8 Bit (1920×1080). There doesn’t seem to be a 29.97 1080p option.

Sorry, here’s a correct screenshot post (I hope).

[Alex Elkins]

To me that looks exactly how I’d expect a DSLR shot of a load of branches to look.

It’s not unusual that DSLR material would have aliasing like this, plus foliage (and brickwork) are notoriously bad for it – certainly doesn’t look like an interlacing issue to me and my guess is that the larger Sony monitor is just accentuating the aliasing.

Try turning the sharpness down on the Sony Bravia. This obviously doesn’t change the fact that the actual material has aliasing problems, but consumer monitors like that do tend to have the sharpening up fairly high by default, which could be skewing your judgement of it.

OR…
I could have it completely wrong, and the image you’ve posted isn’t telling the whole story. Are you seeing similar issues on other shots? (ie shots other than branches).

OK then, Log and Transfer won’t work. Try 5DtoRGB. This will be slower, but a better conversion.

Can you post a pic of this footage? I’d like to see if it is indeed interlaced. MPEG STREAMCLIP normally works fine…I think you didn’t get the settings right. And no, I don’t know what the settings are, as I use Magic Bullet Grinder or Log and Transfer to bring in my DsLR footage

The sharpness on the Sony is at minimum. But yes, it also shows up on some foliage, which sometimes comes out a little clumpy.

Is this something that a frame rate like 29.97 rather than 23.98 will accentuate on the DSLR? I agree that there’s no use changing the monitor settings.

Shane, I just downloaded 5DtoRGB and I’ll try that as well.

[Enrico Lappano] “Is this something that a frame rate like 29.97 rather than 23.98 will accentuate on the DSLR?”

No – this is an inherent problem with the way the DSLR cameras work when recording video. Some are better than others. The Canon 1D MarkIV is one of the better ones for instance.

I agree with Shane that 5DtoRGB is worth a try, but I’d be very surprised if it made much difference with this sort of problem.
