Compression diff. btw "video" and "DV/DVCpro-NTSC"?

Hello,
I would like to export a sequence in FCP as a quicktime file. My source material is mini-Dv NTSC and was captured as such. What is the best compression setting for me to use in export--> using Quicktime conversion, in order for me to retain optimal quality. I guess I would have put compression to "none" but I don't have that option under settings --> compression settings. I am wondering between "video" and "DV/DVCpro-NTSC", I also notice that they take diffrent amount of time to export, does this have anything to do with the quality? I will be outputting to DVCAM and making transfers to BetaSP.
Thanks alot,
Lela

It's really just a habit I got into back when I was having trouble playing back long, heavy composite projects. It worked, and now, because it doesn't usually take alot of time (gotta go out for coffe and a smoke anyway) I still do it.
As for the archiving. My stuff goes to most clients on Betacam and I do make a DV copy. I just like to keep the show around for a bit, till I'm sure they aren't going to ask for another Betacam copy for a while. So maybe "archive" wasn't the right word.
Have fun

Diff btw ITS and webdynpro

Hi All
Can anybody throw a flavour on Diff between ITS and webdynpro
In SRM 5.0 they are using ITS But in SRM 6.0 they are using webdynpro technology

Hello Sandeep,
I am not too technical but ITS & webdynpro technologies pertain to the web interfacing with the application servers i.e.when a user makes a transaction thro' web browser the ITS /Web dyn pro enables to reach the application server and gets back the result/retrieval of the required data in to user's presentation layer.
It is learnt that the Web dynpro technology is faster in retrieval of the data compared to the ITS.
May be the following links would be of much help

Diff btw stop and Continue

What is the diff between Stop and Continue?

STOP
Effect
The statement STOP is only to be used in executable programs and in the following event blocks:
AT SELECTION-SCREEN (without additions)
START-OF-SELECTION
GET
You leave these event blocks via STOP, and the runtime environment triggers the event END-OF-SELECTION.
Note
The statement STOP is forbidden in methods and, since Release 6.10, leads to an uncatchable exception during the processing of screens called with CALL SCREEN and in programs not called with SUBMIT.
Example
Ending the event blocks GET sbook after max postings have been issued, and branching to END-OF-SELECTION.
CONTINUE
Effect
The CONTINUE statement can only be used in loops. If it is used, the current loop pass is ended immediately and the program flow is continued with the next loop pass.
Example
A loop pass is exited using CONTINUE if the loop index sy-index is an odd number.
DATA remainder TYPE i.
DO 20 TIMES.
remainder = sy-index MOD 2.
IF remainder <> 0.
CONTINUE.
ENDIF.
WRITE / sy-index.
ENDDO.

Diff btw RLINK and xMII

Hi,
can anybody please clarify my doubt
what is the difference between RLINK PPPI for SAP and xMII?

Vijaya,
RLINK PPPI is developed by OSI the same people who devliver the Plant Information (PI) historian and no doubt RLINK is developed primarily for use with this system. Whereas xMII will work with any historian that supports OPC or OLEDB including PI. In short the PPPI product is probably not as flexible nor as robust as xMII.

DV/DVCPRO NTSC Compression not working

When I export a sequence to QT movie using DV/DVCPRO NTSC compression (either directly to a QT movie or using QT conversion) I get what looks like a solarized effect (maybe 6 colors total) and the colors are all off - mostly browns and dark tans with hard lines between them, grainy.
If I export with no compression, it looks fine.
It also looks fine in FCP itself during edit and playback, etc.
If I take this project and clips to another machine, it exports into DV/DVCPRO NTSC with no problem.
This just started happening. It was working fine for months with the same settings.
I've tried archive and reinstall the OS system as well as trashing and reinstalling FCP. No change. Using OS 10.4.11, FCP 5.1.4.
I don't know what else to do other than wipe the drive completely. All suggestions appreciated.
Thanks
Paul

Hi Paul
in your first post you said that exporting without compression was fine, now you say that it also has issues and that exporting on another machine is ok.
1. Given that you want to go back to tape, export at your sequence settings to maintain quality; actually selecting the same settings as the sequence settings should see no difference in quality. If you are outputting the finished product back to the same tape that the footage originated from there is no need to change codec, you are better to leave it the same.
2. The fact that the export is seeing problems on one machine and not another suggests that something is wrong on machine one. Trash the prefs for FCP, run some system maintainence on it as well, eg. Disk Utility.

Hello All...
Back after a brief absence, things look a little bit different.
I'm trying to take a 16 minute mini dv video and compress it for use on the web. I'm interested in any suggestions you may have on settings for the video and audio tracks. I've tried using Sorenson 3 (15 frames, key frames set to automatic, 320 x 240) for video and IMA 4:1 (mono) for audio. The resulting video looked great but the file size came in at about 255 Mb.
Thanks!

Thank you for the replies. Everyone was correct about the jack, interface, and phasing problems. I have been unplugging my motu audio interface and then using headphones at work. I have not changed any detailed audio output settings in logic. When I read that the jack might be a problem I tried switching headphones. This actually helped. I am using dre-beats headphones and they seem to be having issues with the mac/jack-(the phasing/panning problems. I can use these headphones with other devices but not the mac. I have to use ipod ear buds and the phasing seems fixed. Hopefully this information is helpful to someone else.
If anyone knows how to correct this issue please let me know its difficult to know what my final mixes are going to sound like and I have had to keep bouncing everything into i-tunes- sync to ipod and then listen in my car radio.

Importing Video from Video from GV-DV1000 NTSC Sony VTR - Image and Audio out of sinchronization

Hi, I´m using Final Cut Express 10.1.1. and to import video, the Sony GV-DV1000 NTSC. My Operating System is Maverick 10.9.2
When I import a Video, the audio and video is sinchronized but when I start to edit, video and audio are not sinchronized.
The connection from the VTR to the iMac is thru a firewire cable to a thunderbilt cable. There is a way to avoid this problem?
Thanks for your prompt response,
Sincerely,

Video and Audio 2 frames out of sync: DVCPRO HD 720p60. Can you help me pl?

Hi,
I'm capturing DVCPRO HD video 720p60 [shooted with a Panasonic VARICAM (AJ-HDC27)].
I'm using a Panasonic AJ-HD1200A videorecorder (by the Firewire port):
on the Final Cut Pro (5.1) timeline, video and audio are out of sync (audio comes two frames before video). Why?
Can someone help me please?
Thanks a lot.

This is normal when capturing DVCPRO HD via firewire. Happens to me all the time. I simply slip the audio back two frames when I drop them into the timeline. Only way to fix this is to get an HD capture card like the Kona LHe or Decklink Extreme and capture the footage via HD SDI as DVCPRO HD. Doing that will eliminate the sync issue.
It is all FIREWIRE's fault...

Whats is the diff. btw classic badi and new badi

Hi guy,
I just found out that there is classic and new badi implementation in SE19, I would like to check out with u guys on what is the diff btw the two?
thanks.

Differences Between Classic and New BAdIs
Classic and new BAdIs differ in a number of features that are important for migration:
1. BAdI object
a. With classic BAdIs, a BAdI object is created by calling a factory method, and referenced via a reference variable of the type of the BAdI interface.
b. With new BAdIs, a BAdI object is created via the ABAP statement GET BADIas a handle for the calls of BAdI methods, and referenced via a reference variable of the type of the BAdI. A BAdI object is an instance of an internal BAdI class, which otherwise is invisible to the outside.
2. Passing comparison values for the filter
a. With the classical BAdIs, the filter values are stored in a structure and passed with the call of the BAdI methods.
b. With the new BAdIs, the comparison values for the filters used to search for implementations are passed when the BAdI object is created with the GET BADIstatement.
There is no way of migrating the call of the factory method one-to-one into the ABAP statement, because GET BADI can also return an existing BAdI object, which is not possible with the factory method.
3. Calling BAdI methods
Passing comparison values for the filter
a. A classic BAdI can be called only once and the call positions are registered centrally.
b. With new BAdIs, multiple calls are possible and the call positions are not registered centrally.
For the above reasons, an automatic call migration is not possible.
Have a look at below link.

IOS 6.1.2 STILL does not fix massively distorted and compressed audio from videos

I bought an iPad to show prospective clients my video and audio recording services.
Ever since changing to iOS 6 the audio from all the videos that I have put on the iPad are completely
distorted and overly comressed. The slightest bass note and everything is garbled beyond belief.
The same videos on my iPhone 4 sound wonderful as they should, but the same videos on the iPad
are completely wasted. Playing the sound through the built in speaker of the iPad proves good, but
the headphone output is horrible. Audio from other sources is clean and undistorted.
I spoke to Apple Care about six times, and two different Senior Advisors neither of which did anything for me.
I had the local Apple store replace the iPad but that made no difference.
I now have two iPads and they both have the same exact issue.
It's just pathetic that Apple has not addressed this.
Dan

Addressed an issue that only you seem to be having?
Apple offers great service but not this personalized.
I have never had this issue and I transfer or watch a lot of video to my iPad.

Question on exporting out to DV/DVCPRO - NTSC

I am trying to conform footage to my Easy Setup in Final Cut Pro and for some reason, it won't. My Easy Setup is based on the DV/DVCPRO - NTSC setup with the aspect ratio being 720x480. When I export the footage out, it gives me 720x480 (640x480). That's fine.
So I switch it to NTSC 720x480 4:3 and it still exports out as 640x480.
I try the custom option and type in 720x480 and it still exports out as 720x480.
What am I doing wrong? Is it trying to conform the aspect ratio to what the original video size is? Thanks.

What am I doing wrong? Is it trying to conform the aspect ratio to what the original video size is?
You are confusing the rectangular pixel encoding matrix (720x480) with the square pixel display dimensions (640x480). You must remember that DV was historically developed as a broadcast compression format to more closely reflect the rectangular pixel presentation of older CRT televisions having 720x480 rectangular pixels to display the equivalent of a 640x480 square pixel image.
So I switch it to NTSC 720x480 4:3 and it still exports out as 640x480.
I'm not quite sure what you saying you want to do here. If you were to display 720x480 rectangular pixels on a square pixel device (e.g., a computer monitor, HDTV, etc.), then at 720x480 square pixels the image would look somewhat squat with people and objects looking shorter and fatter than they should be because you have changed the aspect ratio from 4:3 (640x480) to 720x480 which would then have an actual square pixel aspect ratio of 1.5:1 (or 3:2) rather than 4:3.
As an aside, a 16:9 anamorphic DV file would also encode to the same 720x480 data matrix but (as long as the flag is not lost) actually play back at either 640x360 or approximately 853.3x480 depending on the application in use and you would see an entry of 720x480 (853x480) or 720x480 (640x360) on the player Inspector or Info window.
So, unless you are saying that your file has lost its anamorphic value (which can happen in some workflows), it sounds as if everything is working correctly.

Blurry footage when using Apple DV/DVCPRO - NTSC

I'm working on a 30 second spot that I need to upload to the cable company and they only accept .mov files. It's SD footage. It was shot and is being output as 720x480i. I tried sending them an uncompressed .mov file but they said they couldn't use it (wouldn't open with their conversion system). The guy at the cable company is telling me to use the Apple DV/DVCPRO - NTSC codec to compress it, but when I use that the footage looks pretty blurry compared to the uncompressed version.
I even took it home and checked on my Mac, which looked a little better, but still blurry. I tried exporting it using the h.264 codec and it looked better (still not quite as good as the uncompressed, but pretty close). The strange thing is the the h.264 compressed file was only around 50MB while the DV/DVCPRO - NTSC file was around 100MB.
Is the h.264 codec just that much better that a file can be half the size, but still look better? Or am I just seeing the blurriness because I'm watching them play back on a computer monitor and if I were to send him the DV/DVCPRO - NTSC compressed file it would look fine on TV?

Well, my guess would be that you're witnessing the artifacts of displaying interlaced video on a progressive display. The DV codec is interlaced by its nature, and your computer screen is progressive by its nature. Typically, interlaced video will not look its best on a computer screen, and that's why you'll always hear recommendations of previewing your interlaced material on a properly calibrated NTSC/PAL display. It's just too difficult to judge problems with interlaced footage on a computer screen.
I imagine that the difference you're seeing between the DV export and the H.264 export is that the latter was deinterlaced, and therefore looks "better" on a computer screen. That said, it's not going to look good on a television, which is the intended output. And, I'd bet dimes to donuts that your cable company would scream bloody murder if you sent them an H.264 encoded video in an MP4 container--they just won't know what to do with it. Believe me--I've tried. Send them that DV MOV, and your life will be much better :)

Converting CODECS TO DV-DVCPRO-NTSC

Need advice on converting formats and compression systems to work in FCE without constant rendering. I'm not sure I understand how this all works. As far as I know in order to work “efficiently” (i.e. without rendering all the time) all clips need to be imported into FCE using MOV format with DV-DVCPRO-NTSC compression.
I have video from a Canon G-11 digital camera that downloads automatically into iPhoto. When I drag a clip out of iPhoto it’s in MOV format but with a codec of H.264. To get it into DV-DVCPRI-NTSC compression I have to open QT-7, open the clip then “export” it with options set correctly…then I import the clip into FCE. This is not so bad but I can only do one clip at a time. I literally have dozens! I must be missing something. Is there a better way or is there a way to batch convert in QT-7?
I’m using FCE 4.0.1 on a MacBook Pro with OSX10.8.4. Thanks for any information.

Thanks MtD and DH,
Sorry for the delayed response. First, thanks MtD for the tip on Streamclip. It works!! I can now batch convert. However, I'm embarrassed to admit I do not know what "Are you editing on a DV timeline?" means. I have no idea!. But I guess it doesn't matter since I'm back in business.
DH, I'm mixing SD video from 1st generation Flip camera with SD from a Canon camera...so no HD. However, I am clicking anamorphic on the item properties screen and using the wide screen format. This may be wrong when I export the final sequence from FCE...but I'm taking a chance it will play properly when I burn it to a DVD.
Again, thanks to you both.
