Settings for a 720/24pn downconvert to SD 29.97?

I have a 720/24pn sequence in FCP. I want to output it to a miniDV tape. I know that I can drop the sequence into a DV sequence in FCP, but won't it look better if I use Compressor to do the downconvert? Intstead of having FCP add the pulldown on the fly as I output?
In Compressor, I use the "DV NTSC" preset, but while that converts it to DV and 29.97, it doesn't add letterboxing. What setting do I change to use letterboxing? Padding? Dimensions? Something simpler?
Thanks for your help,

Actually, the only way you can add pulldown - at least the standard 2:3:2:3 pulldown that most folks desire - within the confines of Final Cut Studio is via FireWire output. If you dropped your 24pN footage into a 29.97 timeline, you'd get what some folks generously call 2:2:2:4 pulldown. To be more honest, FCP simply doubles every 4th frame as the 5th frame. Most (battle-hardened) post professionals consider that nasty.
The benefit of using Compressor to do the downconvert - maintaining 23.98 fps, of course - is to use Frame Controls (you'd need to manually trigger them On) to produce a better quality DV file than what FCP would give you.
In terms of getting letterboxed output from Compressor, if you've got Compressor 3.0.1 or later, there is a preset under the *Pad to:* drop-down for +16:9 (1.77:1)+ that should fill-in the padding numbers for top and bottom (this is all in the Geometry pane of the Inspector). Otherwise, if you can output an anamorphic DV file and have FCP letterbox it for you, (once you drop it into a standard 4:3 DV timeline).

Best settings for t1i 720 clips in Final cut

Hello Everyone,
I am sorry to bug you with this question but will so appreciate it if someone can shed some light on my neck of the woods. I am shooting a small project using Canon's T1i. Beautiful HD videos but after I followed a colleague's advice to use Mpeg Streamclip, I still run into "render-every-time-you-drop-a-clip-on-the-timeline" issue. Is there another compression format that I could/should be using instead? Here is what I have been using to compress my movie files from Canon's native H.264 (which doesn't get along with FCP).
1) File -> Export to QuickTime...
2) Compression -> Apple ProRes 422
3) Quality -> 100%
4) Sound -> Uncompressed, Stereo, Auto
5) Frame Size: 1280x720 (unscaled)
6) Frame Rate: Blending and downscaling unchecked
7) Interlaced Scaling unchecked
Thank you so, so much for your help!
Tupy.

Hi Nick Holmes,
Thank you a million times for your help. Ahhh. So nice to be able to just drop and roll.
And, please forgive my ignorance here. I only found Apple intermediate codec to match the settings does this make sense?
Thank you again, so much, Tupy.

How much leeway for blowing up when downconverting HDV to SD?

Hi. I'm trying to understand how much I can blow up a HD/HDV image when the final format for a project is an SD DVD. How much and why...
I'm working on a DVD of a play. The producer thinks our wide shot is too wide. She wants me to blow it up whenever I use it. I ran some tests blowing up our footage (1440 X 1080) by different amounts and downconverting to SD. I found that I can blow up to 110 pct with no noticeable loss in quality, to 120 pct with some loss in quality (more noise, images are softer), but not so much that I can't use it, and to 150 with so much degradation I can't use the shot.
These results are in-line with my past experience.
My question: why? If I shot on 1440 X 1080 and am using those values for my timeline, and if I'm downconverting to 720 X 486, shouldn't I be able to blow my original footage up to 200 pct with no loss in resolution? Am I missing something? Or is there a flaw in my workflow? Here's how I did the tests:
Export four separate videos from a 1440 X 1080 timeline. Each video was of the same clip. Video one was not blown up at all. Video two was blown up to 110 pct, video three to 120 and video four to 150.
I converted all videos in compressor using DVD best settings for 90-minutes (SD, NTSC, 16:9), burned a DVD using DVD SP and watched it on a flat screen TV.

This is how I'd deal with this ...
Create a new sequence that is DV/DVCPro NTSC 16:9 anamorphic
Put the HDV material in that timeline.
FCP will scale down the material to fill the screen.
In a shot where I want to have a larger image, I'd put it the viewer, go to the Motion Tab and adjust. I can to bring the material back to 100% (which will double the apparent size) before any degradation of image.
When finished, export as "current settings" and use that file in Compressor to generate the files to build the DVD.
good luck,
x

720 24pn to 1080 24p upconvert, and DNxHD or QT uncompressed

I've finished my P2, 720 24pn documentary in Avid and want to deliver a 1080 24p master on hard drive to put to HDCam tape for a Da Vinci color correction.
I've exported a quicktime reference to After Effects and nested the 720 project in a 1920 x 1080 composition (to include all the 4k photos and titles).
Is this the best way to upconvert 720 to 1080? It looks great...
And is using the DNxHD 175 10 bit codec for the quicktime export as good as an uncompressed 10 bit quicktime? The resulting file size on a 100 minute file is 150 GB's vs 1.5 TB's.....
I have searched and searched the forum, but it's not easy to find the Truth!!

FYI for anyone wondering in the future, this is what my Da Vinci artist said:
"At my day job, doing HD spots for Sony Pictures (who are very particular about picture quality), the editors are also using Avid's DNX compression. The settings they are using (at 1080 lines) are: 175X for 23.98 and 220X for 59.94. We've run tons of resolution tests and the clients find this acceptable quality for big media buys (Superbowl, American Idol, etc.)."
Another said that if my original content was film he would go uncompressed QT, but since it was P2, DNxHD 175 is the way to go.
And this article (now a year old) evaluated DNxHD vs ProRes422 and Uncompressed.....
http://www.studiodaily.com/blog/?p=97
excerpt:
As a control, I used Apples Uncompressed 10-bit 4:2:2 codec. I rendered the animation to the ProRes 422 (HQ), ProRes 422, Avid DNxHD 175, Avid DNxHD 115, and Avid DNxHD 36 codecs. (Note: The DNxHD flavors are specific to 1080/24p format video. The 30i versions would be DNxHD 220 and 145.)
After re-importing the results in After Effects, I placed each file in a composition along with the Uncompressed 10-bit 4:2:2 version and used the Difference transfer mode to illustrate where the compressed image varied from the uncompressed. The results were quite surprising.
The DNxHD 175 files difference from the uncompressed was barely visible to the naked eye, but the ProRes 422 (HQ) codec showed significant differences. In fact, in my test, the DNxHD 115 codec also outperformed the ProRes (HQ).

Export settings for RealMedia

Hello everybody
I use PR Pro 1.5 and I created a short video (a collection of .avi source files that lasts no longer than 4 mn) that I need to export in various formats :
WMP and RealMedia for the web, and then AVI, QT and MPEG1 for cdroms, Knowing that the video is meant to be seen by a large audience, and that the original avi files properties are as follows : 720*576, audio rate=1024 kbps, 16 bits, PCM and video image rate 25/s, 29200kbps.
I am really new to all the concepts regarding audio and video codecs, time frame, bit rate etc. so I am a bit at a loss with the export settings.
So far, for each of these formats, my guess would be as shown below :
RealMedia for the web : export / adobe media encoder
codec : "RM9 NTSC download "32"," 62", "128" or "256 "? I don’t know which to choose or why. And just because 256 seems familiar, this is what I would select.
a- for the “Band width” I’d pick up the “56 dial-up” settings because of the large audience it is aiming at, ..
b- as for the “band width rate” I can choose between “variable” (average or high quality) or “continuous”, I’d pick “variable (average) because of the diversity of the audience connectivity
c- and then I have to choose the rate values (default values go from 700 max to 200 average), and here I really have no idea,
d- Then I have two drop down menus (for video and audio), first for a voice codec : there aren’t any voice on my video, so I’d pick the lowest value = 5kbps, second for a music codec : there’s a mp3 soundtrack on my video (rate: 200kbps, 2(stereo) and 44KHz), so I’d go for the “176kbps stereo music” selection in the drop down list, but I keep wondering why not “176 kbps audio surrounding”, or maybe it could be a lower or a higher rate.
e- and then again, I have the same two drop down menus (but this time for video only). Basically for the voice codec I’d make the same selection as above for both the voice and music codec.
a-In the video panel, I can decide to change the dimensions of the images. Default is set to 320*340, but my original files are 720*576. So should I change the default settings to match the real dimension of the images ? If I do so, will that increase the weight of my video and as a consequence the duration of download for the internet users ? Maybe I shouldn’t consider this as it should be a streaming video, … then the weight doesn’t really matter, and I can go for the 720*576 resolution. Except I’ve read somewhere that most servers that host videos are not dedicated to streaming, so in the end, the weight does matter for most internet users wishing to watch a video. … Shouldn’t I on the contrary leave the default dimensions as they are ?
b- and the in the next drop down menu I have to choose the video compression : “Real Video 9” or “Real Video 8” or “Real Video G2”. So … So G2 rings a bell somehow related to servers specializing in streaming (maybe I am completely wrong here … sorry). So I’d pick up that one to ensure that my video will be streamed. Then as an afterthought, as the total length of my video lasts no longer than 4 mn, maybe I can afford any of the two other options in the drop down menu. But which one is best ?
Jeez, this is a lot ! I’ll come back later on with my other formats and check if anybody is brave enough to answer !
Thanks in advance anyway

dj paige ... thank you.

AE Composistion Settings for DVCPRO HD footage?

Slightly unrelated but giving it a shot anyways .
I have some DVCPRO HD footage. Here's the clip settings for it (digitized using Final Cut Pro).
Vid Rate: 23.98 fps, Frame Size 960 x 720, Compressor DVC PRO HD 720p60, Data Rate 5.5 MB/sec, Pixel Aspect DVCPRO HD (720p60).
In After Effects, what should my composition settings be? Or should I be going for a specific preset? Using After Effects 6.0, doesn't have a DVCPRO HD preset.

I'm not familiar with any of the formats, nor how they compare with each other when put side by side. I'm guessing whatever I get from my After Effects composition would be compatible with what's in my FCP timeline. I'm actually asking this on behalf of the editor who is also new to these new HD-related formats. Not exactly sure of his timeline settings, but when he puts in his DVCPRO HD footage, there's no rendering required. So I guess Final Cut's DVCPRO HD preset settings? If FCP has such a preset that is.
Even better would be if I could somehow export a lossless clip that I could put into my FCP timeline and render out perfectly fine. Example i'm more familiar with: using clips with no compression in DV NTSC timeline.

Sequence settings for 16:9

Hi,
Just doing some PAL tests of 16:9 HD to 16:9 SD downconvert.
What are the sequence settings for this?
If I use the normal DV PAL 48khz, the VIEWER window shows a normal 16:0 ratio, but the CANVAS window shows a letterboxed 4:3 window. When I export this project, I get a letterboxed 4:3.
If I need to give my European client a 16:9 SD project, what are the sequence settings.
Thank you kindly!

Thanks Michael,
I still get images in FCP and QT exports that are letterboxed. Is that normal? I guess I assumed 16:9 FCP project windows and QT export movies would be all image and no letterbox within a 4:3 window.

System Settings for Kodak Zi6

Yikes, this is driving me nuts.
When I export from FCE for youtube, I'm getting some funky borders/margins. And I think it is my system settings.
I'm eager to export to 1280 x 720, as that is what YouTube says is it's max.
What do I set for System Settings for the HD from a Zi6?
Thanks so much.
Brad
For a bonus question, do I have to change the settings when I use lower quality video from my Casio Exilim, which I only rarely use, but sometimes like to mix video from that camera in w/ video from the Zi6
THANKS!

here's the youtube video to see the margins http://www.youtube.com/watch?v=4B9SkvhoUYw

Universal publish settings for a particular project?

i was wondering if it was possible to set up a universal publishing directory for a given project so that i do not have to go and manually change the publish settings for each individual .fla.
any help would be much appreciated.
thanks
angus

Gustavo,
Your end result should be DVD, which is 720 x 480 NTSC or 720 x 576 PAL.
Use a SD widescreen sequence setting and downrez your HDV or let the camera do that for you by capturing SD format. If you have captured HDV, you can either downrez by using Motion/Scale to fit your SD resolution or use Scale to frame. The latter has a small drawback in that it will result in small black bars left and right, that will normally not show up when played on a TV.

H264 - Can anyone beat these settings for quality ?

I am preparing a couple of projects for the web.
My task is to get my exported MOVs to the web guy in the best quality and then he can work with them and convert them to FLV.
I am using H264 (settings below).
Can anyone confirm that these settings are the best possible to use to get the highest quality, or suggest something else?
File Extension: mov
Estimated file size: unknown
Audio Encoder
IMA 4:1, Stereo (L R), 48.000 kHz
Video Encoder
Format: QT
Width: 720
Height: 480
Pixel aspect ratio: NTSC CCIR 601/DV
Crop: None
Padding: None
Frame rate: (100% of source)
Frame Controls On:
Retiming: (Better) Motion Compensated
Resize Filter: Linear Filter
Deinterlace Filter: Better (Motion Adaptive)
Adaptive Details: On
Antialias: 0
Detail Level: 0
Field Output: Progressive
Codec Type: H.264
Multi-pass: On, frame reorder: On
Pixel depth: 24
Spatial quality: 100
Min. Spatial quality: 25
Key frame interval: 24
Temporal quality: 50
Min. temporal quality: 25

Looks pretty good to me. Have you read this article before? http://www.apple.com/quicktime/tutorials/h264.html
You know Flash Player 9 supports H.264? No need to re-encode to flv, if you can avoid it. Depends if you want to support earlier versions of Flash Player.
I would strongly recommend doing some short tests before you start encoding everything. It will save you a lot of time doing some short 10-20 second tests (just set in/out points in the Compressor Preview window). I would maybe try setting the keyframe rate to Automatic too.
I see you have frame controls activated. If you would like to save time, you could try this tip (same principle): http://discussions.apple.com/message.jspa?messageID=7309534#7309534
Web compression is all about testing to find the optimal settings for best possible quality/filesize ratio.
If you want the final result to end up as the best quality flv file, I would recommend encoding directly from your source to flv. Going through a heavily compressed long-GOP format like H.264, before encoding to an other heavily compressed format is not a good idea. You would want your video to go through as few generations as possible to maintain quality.

Best settings for PP mov's?

Got a few videos SD 720x486 I need to export from FCP 7 (uncompressed timeline) for use in a Powerpoint - what's best settings for PP? mov, h264, audio at 44 or 48k, what? Should we keep them at full 720 size, probably?
Thanks
K

ON a Mac or a PC?
WMV for the PC but learning how to embed is a function of learning how to use Ppoerpoint, not FCP's tools.
H.264? Dunno, what does the manual for PP say about compatible movie filetypes?
If you are handing these movies off to an experience PP producer, they will be able to give precise specs. If your'e doing this yourself, give yourself some extra time to work out the screwups. We have two wiseguys who insist on doing their own PP instead of letting our PP wonks do the jobs. They have never been able to figure out how to embed or link to movies and they do not understand why we tell them to have the movines in the same folder as the PP files.

Playback of 720 24pn footage

I have a project that was shot on the Panasonic P2 camera, I have the footage in my timeline and it plays at 100% but the actual speed seems to be less than 50%. I'm not sure why. Compressor seems to be correct and the files are straight from the P2 card. also it seems to be a bit stuttery how can I smooth that out. I'm using FCP7.
Thanks
Mark

That may be as I did not change the settings on the camera when I rented it. I saw that it was 720 24pn and expected that would be ok. Guess I'll have to manually speed the footage up. It's a good thing I didn't need the audio.
Thanks

Compressor settings for YouTube for 720p 12 minute 10GB project created in FCPX?

Hey All
Would anyone care to share some settings for compressor please?
I have a 720p 50fps 12 minute 10GB file created in FCPX that using "Publish to YouTube" settings in Compressor is still coming out at 721MB.
It will take me 4-5 hours to upload this to YouTube so need to make the file smaller and who knows how it will play once its up online.
Any suggestions of some other Compressor settings without using too much quality?
Thanks

shippo,
When you reference "50 fps", do you happen to know if that's fields per second or frames per second? Depending on the answer to that, you may or may not need to adjust that.
When it comes to file size, you have frame rate, frame size, compression type and data transfer rate affecting the final size.
As Russ and darby have suggested, data transfer rate is the main thing to experiment with (since you're publishing for Vimeo, the other setting are pretty much locked in).
I have found that when it comes to playing with the bit rate, a video with a 1280 by 720 frame size needs between 4,000 kilobits per second and 5,000 kilobits per second to maintian good image quality. While you might get good results at a lower rate, high contrast areas in the picture are very, very, very likely to show loss of image quality.
If you need to get your video up asap, start the upload late at night. As long as your internet connection doesn't drop out (knock on wood), you file will be uploaded by the morning.
Also, (for what it's worth) is there any place close by that has fast internet that you could use? If you have access to a computer lab at a local community college, a 1GB file will probably upload in minutes rather than hours.

Best HD export settings for YouTube

I am looking for some info on what export settings to use for YouTube with HD video. I want to export everything in 1080 (not 720) so I can also upload to Vimeo. Can someone please explain (or link) to me how I should export.
This is my first time using HD video, I shoot in 24fps onto HDV tapes.
I am not sure what else I need to know (or do) to export in the best quality.
THank you in advance!

Any other input for this topic?
I have been searching around for the past week for a solid export setting.
I've tried the above settings but I have yet to see the final product because it takes FOREVER to export (the estimated time just keeps going up and up, never down).
I found a setting a few weeks ago and used it but I cannot find it again. It did not take too long to export and the final product looked amazing both in Quicktime and on YouTube/Vimeo.
Anyone that would like to share their settings for an upload to YouTube/Vimeo, please do, I am in need.
Thanks!

Is it possible to change settings for an existing sequence?

I am cutting a short "crowd-sourced" class play, shot by parents. I have 4 different types of footage from 4 cameras: Two are 720p (30p), one is a 640x480 .mov and the other was shot in 720p but burned to a PAL DVD so they are .VOB file rips at 25fps, 720 x 576 w/1.2 widescreen.The main camera is an .MTS file (AVCHD 720p)
Since I am planning on ultimately making widescreen NTSC DVD's, I sync'd the cameras in a widescreen-DV sequence, then nested that into a new widescreen-DV sequence and activated the multi-cam. I did all of my actual editing in the new muti-cam sequence - but now I am thinking that I should have started with an AVCHD 720p sequence to sync cameras and just maintained 720p thoughout - until exporting the MPEG-2 file for the DVD.
I can make a new 720p sequence and cut/paste everything from my timeline - but they would still be nested multi-cam cuts that link back to the original widescreen-DV sequenece I setup to sync the 4 cam views. I cannot seem to change the settings for the existing sequence - so is there maybe a workaround for what I am trying to do? Essentially, to trick the new 720p sequence (with all the actual multi-cam edits pasted into it) to linking to a new 720p sequence with the already sync'd cam footage pasted into it? And secondly, will it actually effect the quality of the final DVD output? I may also want to make a 720p web version for Vimeo if feasible...
Any help would be greatly appreciated.

I have created the new 720p AVCHD and cut/pasted all of my edits. That is not the problem.
Almost of my edits (other than a few titles amd stil pics I added) are cuts from the original nested sequence called (4-CAM SYNC). It is a regular NTSC widescreen sequence. In this original sequence, I am scaling the the cameras down to fit the frame and sync'ing the four cameras. I am attempting to get this new sequence to link to a new 720p nested sequence that has my sync'd cam footage - to replace 4-CAM SYNC on the time, while still retaining all the edits I have made - I will just have to change some of my scaling settings in a few clips.
It sure would be easier if I could change the "Editing Mode" parameter under Sequence Settings...
