Recompress HDV Clips to ProRes

I have HDV clips (heaps of them, 1080i/50)and am thinking of recompressing to ProRes for output/rendering time-saving.
If I do this, does it convert the original captured clips from HDV to ProRes?
Am I right in thinking this would be a time saving method?
If I Choose only the clips in the Sequence to recompress, how does it manage to recompress sub-clips? Does it do the whole referenced clip?
Thanks in advance..

Hi MArk, I think you have your answre . I'd like to add that I have been using the HDV 1080/50i to PRORES422 as part of my workflow in FCS2 now because:
• it is much easier to work with than HDV in FCP iteself. This is subjective. Most scrubbing and editing in FCP 6 on this OCTO is smoother using the PRORESS sequqnce than leaving it as native HDV there are small overheads setting up and execting GOP editirs I understand.. especially in this case as HDV is MPEG2 LGOP).
• the CONFORMING to workflow and readiness for some distribution format (e.g. H.264 Multipass segmented transcode ) is demonstrably much faster in COMPRESSOR from APPLE PRORESS than HDV. Note I use QMASTER with VIRTUAL CLUSTERS on this OCTO.
My workflow is simply either to:
• ingest the HDV as HDV1080i/50 and THEN use an FCP BATCH export to maek all the footage I want into PRORES422 1440x1080P or 1080i (use HQ if you want) .. or
• set UP INGESt to encode the HDV on the fly as it ingests the HDV.
From a quality perspective as any one who knows will tell you you WONT get any iprovement in the HDV 4:2:0 by making it proress.. but for me the WORFLOW is much better .. especially o this DUAL QUADCORe beaty.
FWIW.. I am today of all days collecting an Panasonic HVX-200 to go to DVCPROHD (720p/24/25 and 1080p/24/25) AWAY finally from HDV. I'm dumping my 16 month old SONY HVR-Z1P for this reason
that I want to work on PRORESS and have MORE COLOUR info at 422 and now I can really take advantage of bothe apple color.app and my colorista.
anyway I hope that FCP tip helps..

Aren't FCPX and Compressor supposed to be able to export Apple ProRes 422 LT? I just bought FCPX and Compressor and there seems to be no way to transcode HDV clips to Apple ProRes422 LT. Before buying I read LACUG tutorial by R Taylor that says it can.

Tom is right. Codecs are shared software system-wide ("Core Video"). If you cannot find the option with any software (such as MPEG Streamclip), you won't find it in Compressor or FCPX either. The Quicktime ProRes codecs is part of the FCP menu > "Download Additional Content" you need to make after install FCPX (or Compressor.) These "pro video" codecs are part of all "ProApp" licenses for video related software from Apple (QT7Pro, Motion, Compressor, Final Cut, etc....) [you can also download them here: http://support.apple.com/kb/dl1396]
Most articles/tutorials you read by "long time" users are apt to assume the reader has been working with pro-video on Macs since the days of disk installs (like they have). In those days, the installation of those codecs wasn't even really an option (well, it was if you did a custom install - but who *didn't* install all available codecs??), it was automatically installed with the main software. Since the "App Store" venue... things have changed somewhat.

Any known issues with Premiere CC and imported HDV clips?

I'm having consistent difficulty with Premiere CC playback of HDV video that originated in FCP 7. This was not an issue in Premiere CS6. The problem is dropout and pixelization which is consistent, pass after pass, and occurs at the same TC location on some clips. It is almost like some clips are corrupted in a consistent manner, while others are not, and don't seem to become corrupted.
For a variety of reasons, I still shoot HDV on a Z1U, and use an old FCP7 workstation to digitize media. I then import these individual video clip files into CS6. These are clips that play correctly in FCP, Premier CS6, and in the Finder, and Quicktime Pro, but not Premiere CC.
I have Dropboxed a sample clip to my service contact at AJA, and she is reporting the same issue with Premiere CC. (The technical support at AJA is the best I've experienced in over 30 years of video production).
The same issue presents itself with HDV clips that were converted to such from .m2v via Clipwrap.
Any other types of media play correctly within Premiere CC. For example, I have a CS6 project that is nothing but After Effect CS6 anims comiled into a program in Premiere CS6; it plays perfectly. So do any media that Premiere CC puts through its own conversion or import "routine," like AVCHD. Even XDCAM clips that went into FCP via XDCAM Transfer play well.
Any thoughts?

Tim,
I would assume the clips work fine in FCP7, so you're not totally busted. Maybe try using Compressor or AME, like the other guy said, to export them in another format; I'd recommend Apple ProRes 422. Fallback is to work in FCP7, as the tapes are gone.
When I 1st posted this problem, I left for vacation. I saw briefly that someone suggested a plugin in another reply, but I haven't had a chance to pursue that yet. I'm in northern Michigan (USA) with limited access to email. I'll do some follow up this Monday when I return. Good luck!!

Random HDV clips choppy

Hi gang,
I'm editing HDV clips (1440x1080/25p) on a MBP with 4gig ram and FW800 drives.
Now, opening the clips in the viewer and playing them back is generally fine, I've done a fair amount of HDV (and ProRes) stuff on this MBP and it can handle it fine.
However - occasionally some clips will playback choppily, and watching the CPU meter rise the computer is obviously struggling playing the clips back. It's always the same clips, in other words, ones that are affected stay affected, all the other clips are fine. This is about, what, 5 clips in 500 odd.
Why would most HDV clips play fine, and some seem to require a lot of grunt to playback? Is it to do with edit points causing the HDV compression to require CPU intervention?
And most importantly, is there anything I can do about it? it's not the end of the world, as I can drop them into the timeline and render, but it's bugging me...
Edit: Ok, this is interesting. The affected clip is actually according to FCP an HDV 1080i50 clip. However, the data rate is consistent with my 25p footage and not the other 50i footage, and more importantly, looking at the footage at 100%, it is not interlaced at all.
So it would seem that FCP has incorrectly interpreted this footage on ingest as 50i when it is actually 25p - and presumably because of this is having to do some CPU mojo to play it back, resulting in choppy video.
Any thoughts?

Oh well - I used Compressor to pretend that the footage was progressive, then converted it out to ProRes and that has done the job - and it's what I will do if/when this situation happens again.

HDV exported as ProRes 422 produces 4:3 in iDVD?

AVCHD exported from FCP X as ProRes 422 works perfectly in iDVD producing a 16:9 DVD.
HDV doesn't, even though QT Player plays it perfectly.
The odd thing is that 4 years ago, using legacy FCP my exported HDV videos had no problems being recognised as 16:9 by iDVD.
So why are FCP X produced HDV videos not recognised as 16:9?
P.S. I know that iDVD never recognised DV in the 16:9 format but it always worked with HDV.
Incidentally, the old trick of opening it in QT Pro and changing the frame size to 1024 x 576 does not work!

The AVCHD was actually 50p footage in a 25p project exported as ProRes via Share>Export Media.
Worked perfectly in iDVD.
The HDV was standard 1440 x 1080 treated just the same and came out as 4:3 in iDVD which I suppose is what it is when the pixels are square.
I have found a workaround/solution.
Make a ProRes 422 custom preset in Compressor specifying a frame size of 1920 x 1080.
Works perfectly and iDVD sees it correctly as 16:9.
Only downside is that converting using the custom preset takes at least twice as long.
Regarding the weird moire pattern when using FCP 7, I have just exported the clips as ProRes 422 1920 x 1080 and they appear normal.
The moire pattern appeared when I exported the clips as native HDV, something I always did years go with no problems.
So I have found workarounds but not solutions.

Need to put HD clips in SD sequence without aliasing, any way to do this without converting clips to ProRes?

Editing a 1080p project shot with Canon 5DMkii.
Have a 1080p H.264 sequence that I planned to change to ProRes when all finished, before exporting to make a DVD.
Many shots have problems, and the only way to get around them is to reframe.
I figured, no problem, DVD video is SD, so I have 600+ pixels of frame-height to play with.
Now I have a rough cut and I have put some clips into a sequence preset to 720x405.
Unfortunately, when the original clips are anything other than 100% of their 1920x1080 size, it’s aliased as heck.
EXCEPT when you convert the original clip to ProRes.
I didn’t convert to ProRes before editing because it quintuples the size (the project has 45GB of footage and my internal 1TB HD has limited space), plus on this project the small difference in final-product quality that converting before editing brings wouldn’t matter.
I really do need to reframe many of the shots, and I wouldn’t terribly terribly mind converting to ProRes now, except that when you do, Compressor adds “ProRes…” to the new clip name, so you couldn’t just reconnect the already-edited sequence with the newly converted clips (or could you)?
So,
Can the downsizing of HD clips in an SD sequence be done without aliasing?
If not, can a whole sequence (15 minutes) be reconnected to clips to clips that
have the “Apple prores 444 hq” added to their name? (I tried and the converted clip is grayed out, can’t select it)
3. If not, can the whole 45GB of footage be converted to ProRes, but keep original names unchanged?
If none of the above is possible, any other solution?
Thank you very much

That is a non-standard sequence setting. SD in NTSC land isn't 16:9. It is 4:3 anamorphic. 720x486...anamorphic (squeezed).
Editing H.264 straight from the camera is wrought with errors. Besides the sluggishness of it, the non-RT playback...exporting has all sorts of issues. Not exporting proper sections of footage, not exporting the full sequence (the tail might get cut off), loss of sync upon export...much more. All of those issues have been mentioned on various FCP forums. H.264 is not a codec FCP 7 deals with well at all.
Converting to ProRes before editing is your only way to ensure vary little issues. And converting to ProRes 422 is recommended. Not HQ...not 4444. Your footage will not see any benefit from those formats, even though they sound more impressive. All you will get is larger files. Heck, since you are going to DVD, ProRes LT would be the optimal choice. Even if you went to BluRay, ProRes LT would be fine for that format. H.264 is an 8-bit format...ProRes LT or 422 will get it to 10-bit, and allow for better grading. But ZERO benefit will be had with HQ or 4444...those are for other uses...with higher end formats.
Not enough space? Get another drive. Internal SATA, if you have a MacPro...are 2TB for under $150. You can get an external 2TB for $200-$300.
3. Yes...use MPEG STREAMCLIP to convert the footage to ProRes. 422 or LT are recommended. Then you can reconnect, but you will need to make a new sequence that is ProRes...not H.264.

Aspect Ratio HDV clip from FCP to After Effects

Can someone help me with exporting from FCP an HDV clip to After Effects? What I am doing is trying to export an HDV clip from FCP to AE but when I import it into AE the aspect ratio is all off. I have an HDV 1080i50 easy setup timeline and I am exporting from that as a quicktime movie (not conversion) with the current settings. When I bring that into AE I have a HDV comp set up and I drop the FCP movie into that comp. My FCP movie is 1920 X 1080 and is bigger thant the AE HDV Comp. Why? Shouldn't the sizes be the same since they are HDV? Please help
Tim

HDV is 1440 x 1080 native so if you have output from FCP that is 1920 x 1080 it is being misinterpreted by AFX.
Try creating a new comp in AFX using the HDV easy setup but set the frame size to 1920 x 1080 manually and see what that does.

Using HDV clips from Final Cut in a 4:3 iMovie Timeline

I'm trying to use HDV clips in a standard def, 4:3 iMovie file. I export them as full quality QT clips out of my FCP timeline - to the desktop - then when I drag them into my iMovie file - they squish instead of letterboxing. I've tried everything but can't get it to work. Some clips import with the letterbox and others import anamorphic style. Very strange.
It looks like iMovie likes the .dv file extension - but I can't get that with the QT clips I make in FCP - when I use DVStream as an export the quality goes way down. I also tried converting them in Quicktime - but that isn't working. Any ideas?
Again - just trying to keep my 16:9 clips in 16:9 and not squishing them to be 4:3. I'd be happy getting my QT clips from FCP to be .dv files even.....
Thanks

It looks like iMovie likes the .dv file extension
Yes, a correctly 4:3 or 16:9 flagged .dv imports best and most predictably to iMovie
when I use DVStream as an export the quality goes way down.
Of course there is downscaling when converting HD to plain lower res DV. Also remember that QT Player by default shows low-res preview of .dv -- you have to turn on HQ display to see all quality.

Is it possible to create a dolby 5.1 video with HDV clips in Premiere Elements 9

I am trying to take the stereo input of the HDV clips and use those for Front Left and Front Right. I would like to add some stereo music in the two back channels and add a narrative for the center channel. Is this possible in Premier Elements 9?
Thanks for any pointers...

No, unfortunately you did not miss something.
The same, or very similar, question comes up in the PrPro forum, quite often. There, it's usually along the lines of "why do I have to buy the SurCode plug-in? Why is it not included in the price of the program?" There, the answer is that if it WAS included, the price would go up by about US $ 250 for every copy of PrPro, whether the user ever needed to do DD 5.1 SS, or not.
Personally, I was so impressed by the SurCode plug-in for PrPro, that I bought two licenses (no discount for multi-user licenses), and nearly every Project contains DD 5.1 SS, that gets authored in Encore. I also got the SurCode DTS Encoder (not a plug-in, but a stand-alone), and many Projects also have DTS as a supplemental Audio Stream.
Not sure if PrE will ever have DD 5.1 SS output, due to the cost of the DD licensing.
Now, some NLE programs DO offer 5.1 SS, but not sure how many are fully DD (Dolby Digital) compliant.
Good luck,

Cropping Single HDV Clips in Final Cut Express

Hi,
I am using Final Cut Express to edit short HDV clips (max 6 sec) of microscopic biological specimens for web viewing. For my purposes I use HDV for a higher resolution but I would still like to change the frame size (width and height) of my clips in the Canvas before exporting. In order to remove unnecessary background to reduce file size and retain a high quality clip. In older versions of FC (Pro 2 or 3) you could go to Sequence Settings and change the frame size by changing the apect ratio to custom but FCE doesn't have this option. I need to know if it is possible to do this in FCE before exporting so I can adjust my frame size multiple times if necessary.
PowerBook G4 Mac OS X (10.4.6)

FCE is not a resolution independent application. It is resolution specific HDV or DV. You can also crop for final output on export with an application that has a cropping function.

IMovie 6, Imported HDV clips are squashed?

I was checking out iMovie 6 to see whether it worked on Lion OS X 10.7.2 and it appears to do so.
However, when importing some HDV clips captured in Final Cut Pro it appears to play them squashed, obviously using their 1440x1080 measurements.
As iMovie 6 specifically lists HDV I would have thought it could cope with HDV's wide pixel aspect ratio.
Am I doing something wrong or is this an inherent problem when trying to use it on the latest OS ?
Note that I am referring to HDV shot on a mini-DV tape and not the latest AVCHD varieties.

I think I have got it !
FCP captures HDV natively but iMovie 6 can only correctly deal with HDV when it is converted to Apple Intermediate Codec during capture. (Under those circumstances I am surprised it worked at all).
I used Streamclip to convert to AIC and everything appears to work well.
I am quite astonished that iMovie 6 has bucked the trend of planned obsolescence and appears to work well with the latest OS.
Perhaps it is due to its simplicity and hence rugged design.
The only thing I can't get to work is the "Themes".

HDV clips out of FCP to After Effects.... Settings???

Hi,
I am capturing my HDV clips with the apple intermediate codec 1080. And exporting like that to. But when I make a 1080 comp. in AE it is square. I turn the 4:3 aspect ratio off but to no avail. Any idea what I need to make my settings in the AE comp.
Thanks a bunch

Does it look squished horizontally? If so, make sure there are no 'anamorphic' settings checked in AE, or in your export settings out of FCP. That would make it look square.

Is there a Sony HDV 108050i to ProRes 108050i codec?

Hello all:
I'm having a busy day on the forum.
So here's the deal:
I have a Sony HDV-Z1U camcorder. I want to shoot in HDV 108050i (PAL) and I want to edit in ProRes 108050i.
The thing is I can't find a codec that will let me encode/capture HDV to (Sony) ProRes 50i. I can only find a codec to encode/capture at 60i.
Am I missing something?
Thanks...

the Panasonic GH1 can record both in AVCHD and MJPEG. With the hacked firmware the MJPEG datarate is currently running around 70mbit/s, which can handle a smooth gradient over about 14 stops. MJPEG is a contained video file that QuickTime can play, directly out of the camera, however to edit it, FCE needs to convert it to AIC, and this process degrades the shadow detail, and gradients break up.
But even with the AVCHD, currently running around 30mbit/s, and doing simple shots like of a live concert, I can see the same separation in gradients after conversion that are not present beforehand.
is that better? I am now also a bit puzzled by one of the AVCHD archives seeming to be damaged, as FCE says it has an "invalid directory structure".

Converting HDV clip to Flash

Hello,
I am wondering if there is any way how to convert HDV clip into Flash .flv file, keeping 16:9 ratio.
I only manage to convert it into whatever conversion is available in Compressor, like .mov, H.264, etc.
But how can I end up with Flash file?
Thank you so much for your advise.

Those are mutually exclusive operations, file size and image quality.
Adobe's own media encoder cannot compress the their own FLV any more efficiently using preset. if you get in and tweak every scene change you can expect some fabulous results at the expense of lots of time and effort. But the file won't be significantly smaller.
Again, suggest you hit Adobe.com and get everything they have to offer on encoding for Flash, there's tons of free information, not al of it is easy to find, hidden in support forums, tutorials, blogs. But it's there. And you can search here for "flv" we see the topic daily.
But consider that you shot 720 and are now smooshing it to less than VHS quality and wondering why it's not both lovely and small at the same time. It's a tough compromise, very difficult to achieve, especially if you are going to open the frame controls and start applying white restore, intelligent deinterlacing, gamma, and contrast adjustments.
Sorry not to be able to give you a magic formula.

Can KN3 play HDV clips

I am a Wintel user, looking to change to Mac. I'm seriously looking at the MBP. I recently bought a Sony HC1 HDV camcorder. I would like to take the HDV clips and embed them in a Keynote file for professional presentations. Does anyone have any experience with this?
Thanks in advance.
