First off, I have a Sony HVR-Z7U and using FCP.

Ok, ClipWrap was working great for all my needs, until I got out on a shoot today and ended up shooting a few segments about 1 hour each in contiguous length.

The problem is that there are multiple m2t files in one contiguous recording, and when I try to splice the files together, I'm not having a lot of luck. For me, the first two frames of any file I ClipWrap are unusable. They are basically garbled.

Has anyone had any luck in working with longer recordings (longer than 20 or so minutes - due to the 4GB filesize limitation) and the Sony Memory Recording Unit HVR-MRC1 that comes with the HVR-Z7U?

TiA!

I Mike we emailed a while ago about your supporting 1920x1080 TOD (.m2ts) MPEG-2 files. Any news? Now that VisualHub has gone out of business, the JVC camcorders have only Streamclip!

Hi,

I've just this afternoon downloaded Clipwrap (the trial for the time being at least).
Impressed with the speed of the convert!
However, I was wondering if this can be used in anyway for overcranking - I usually used the following workflow:

DVHSCAP > Mpegstreamslip > Conform to 25 (when recording with HDV-SD50p)

TO my eyes...and unless I've done something drastically wrong, the resulting footage has deteriorated pretty badly - one of the reasons I rarely use the method (saying that, I've seen it done much better on some of your posts in the 'show your work' section).
I was hoping clipwrap might generate much cleaner footage, but I cannot seemingly have FCP injest the .mov files originated as HDV-SD50p footage: I get a black image (which requires rendering - which I cannot they carry out due to a codec incorrect message) although the audio is carried through (720p25 works a treat however).

Apologies if this has already been discussed...I've had a good route through this thread and others to little avail.

Unfortunately the Quicktime HDV codec doesn't support 576p50 or 480p60 so it must be transcoded into another codec like PhotoJpeg. Clipwrap simply wraps 720p or 1080i/p into Quicktime using the HDV codec so it won't be able to work with 576p or 480p HDV.

BTW the HDV codec won't allow speed conforming in Cinema Tools so if you want to overcrank (even 720p60) you must transcode to an all I-frame codec like ProRes422 or PhotoJpeg.

That will explain that! Thanks Tim.

Cheers Tim - I'd been using your overcranking post ( http://www.dvinfo.net/conf/601438-post1.html ) for some time - invaluable as always.
Not entirely convinced by the quality of the footage - it somehow appears grainy, although to be fair the majority of 'slow mo' I show was never in the best light.

Essentially then, as most of my projects will be either on the web or DVD, does clipwrap become a much better workflow both quality wise and time wise? It's a breeze to use.

I am still using clipwrap for all the projects we are doing for our IPTV station.

In nearly two months I have not had a single problem with any clips and the workflow is perfect and very efficient.

I am shooting on a sony S270 and Z7 using the compact flash as the main source with tape as a back-up. We have even done small jobs with no tape as the workflow is pretty bomb proof.

I shoot at 1080i 50i and import to FCP via clipwrap, once editing has finished all masters are exported as pro res 422 1920x1080 at 25p.
