Which Timeline compression codec

Hi I have recently edited a 1 hour presentation in HDV with two PIPs 1/ Large powerpoint slides 2/ Presenter speaking in smaller PIP. When I came to encode this to DVD it took 5 hours. I was advised that if I changed the sequence codec it might speed things up. My question is to what?
I have several more to do soon!
Thanks
Marc

Select the sequence in the browser or make it the active sequence in the timeline window, then type cmd+zero. In the video processing tab, select the sequence to render to ProRes.

FCP Quicktime Compression Codec?

Does anyone have any suggestions on a Quicktime Compression Codec that works well with Final Cut Pro? I need the codec to capture and export quicktime movies in Final Cut Pro. As of right now I don't have the ability to compress.
Is there a standard one?
Is there a 3rd party?

When original post says what it does and your most recent post says something materially different, we all kind of scratch our heads.
Help us in the future with what you wish to do with what and for what.

Which timeline to use for these type of files

I'm using movie files recorded from my Canon Digital Elph that shoots REALLY nice HD footage. It says on my computer that the files are H.264 files in .mov format at 30 fps. Which timeline should I be using? I'm using Adobe Premiere Pro CS4

Thank you Mr. Hunt for yer quick response. However, all I do to find out the file info, is to open
it with Quicktime and there it shows everything I need to know about it. I just need to know which timeline I need for my 1280 X 720 h.264 .mov files at 30 fps. I don't see one that really matches it.

Open Format Timeline - What Codecs?

I'm very excited about this Multi-Format Timeline idea, but I'm having some trouble. I've got a bevy of clips in assorted formats - some h.263 FLVs, some Sorenson MOVs, and some DV Streams. I put them all on the timeline, and FCP wants to render them all, just like the old verion would.
All of these movie formats play through Quicktime just fine. I understand that FCP does not support every codec for realtime playback. However, I can find no list of supported/unsupported formats. Do I need to transcode everything to DV-Compressed MOVs like in FCP5?
Thanks for any hints you might be able to give!

The issue is the sequence setting you have selected and how far your other formats need to be moved, so to speak, in order to conform to the sequence. The further from your sequence settings, the more intense the live transcodee has to be and that is determined by your processors, RAM, and drive speeds.
It is strongly recommended to transcode various formats to a common denominator codec for many reasons but mainly you want to reduce the amount of processing. What format you convert to and when in the workflow you decide to do it is dependent on lots of external factors, mostly your delivery format and when you will reintroduce the original media back into the flow.
The manual has some guidelines but this stuff is specific to projects, each one will need a diferent treatment. But we can't be bothered with the hassles of keeping track of multiple formats, we transcode everything immediately to DV. This would be different of course if we were using different sequences but 99% of our stuff is simple DV.

Fast compressing codec?

Hi,
I use H.264 for most everything. Takes forever but looks great. Now I need something faster and I'm willing to sacrifice some reasonable amount of quality to get a fast workflow.
The end product will be a 320x240 window playing on the internet of a meeting.
What a codec with decent quality and a very fast workflow?
--Darin

Well, I don't know what a 'codec' is. And, I certainly don't know how to "compress it to something else." Any suggestions? (Preferably something that's free!)
Basically, a codec is a encoder/decoder algorithm used compress (encode) and decompress (decode) digital media. VCDs are coded as MPEG-1 with MPEG layer-2 or 3audio files. SVCDs and most DVDs are MPEG-2 video most commonly combined with AC3 audio. iPod compatible videos are either H.264/AAC or MPEG-4/AAC encoded files.
Your first step is to open one of your movies in the QT Player and open the "Show Movie Info" widow. There you will find a "Format:" entry. There you will find information describing both the audio and video format. This should be the "codec" or audio/video format that is not supported by the site.
Your next step is to learn what audio/video format(s) is/are supported by the site to which you wish to upload your files.
The last step is to locate a converter that will convert your unsupported "source" file to a properly supported "target" file format. I suspect that something like iSquint (free) or MPEG Streamclip (free) may be all you need. However, it is probably best to post what you learn here in the event that the specific formats involved have other special requirements or considerations.

Can you see which timeline clips are being used in Media Browser?

I'm a relatively new user and may not be familiar enough with cs5.5 but
is there a way to see what clips are being used on the editing timeline in the media browser.
I open premiere pro - Project is loaded. I edit the scene until it is finished.
When I look over at the media browser, all my raw clips (some of which I'm
using on the editing timeline) look the same - I can't tell which ones I using on the timeline.
The reason I ask - when I fiinish editing a scene it would be nice to glance over at the
media brower folder where my raw clips are located - easily see which ones I'm using because they
are highlighted or checked and then delete the ones I no longer need.
Is there a way to do this now?
Thanks
Jeff

I dont think so but a better way is to look in the top of the Project Window and there is a drop down that will show you all the useage instances of the clip. You can click on them to go to them in the timeline.

Compressed Codec Expanding when Encrypted or Run by an Effect

I'm working on a fun project encrypting video and audio and that part all works fine. Ran into a small problem while I was at it. For some reason the File Expands when I run it into the Encyptor. Now this isn't really the increased overhead from the encryption but rather the file format has changed. For Example
Divx at 570kbps with a 50Meg file becomes
Divx at 1841kbps with a 165 Meg file
This is slightly 3 times larger then what it should have become.
Now since there isn't a standard Divx Decoder in JMF I changed my formates to MJPG just to check. It had a similar effect so I take it since both were compressed the reason for the size change is the compression jumped to the highest factor giving it lossless instead of lossy compression.
Now with audio using MPEGAUDIO or mpeglayer3 the size change is marginal. No more then .1 meg for ever 1.5 megs. That is more of what I would expect from the Encryption Effect.
Now I am running this as an Effect and I believe that the format coming in the inputBuffer is what is bloated because if it bloated after my Encyption I believe it would be impossable to recover the data with my decryptor.
Also if I enctypt and decrypte again on the newly encoded files it does not get larger. It stays at the 1841kbps size which makes me believe it's a default setting that maybe able to be changed. Same goes for the MJPG.
Any thoughts or ideas on how to fix this one will be welcome. I hope I've covered what my problem is properly.
The code is pretty much just a skeleton Effect that uses JCE to encrypt the incoming bytes and set them to the outgoing bytes. If it's needed I'll clean it up and post it so it looks pretty but otherwise it's pretty basic I dont think the codes doing enough. I would certainly hope I'd know if I sliped in a set_kbps_to(int) command some were.

Optimising render time: Which timeline elements/clip effects increase render time?

Hi,
I was just wondering if anybody had further information about Premiere's output render process, specifically the effect clip effects, tracks/layer and clip formats have on render time.
The reason I ask is I seem to be getting inconsistent file export/render times, some projects of similar length and on the same hardware seem to take significantly longer than others.
Essentially I am looking for timeline connfigurations/properties which adversely effect the final output render time. Any further information/documentation regarding this would be gratefully recieved.
Regards,

I am essentially just trying to optimize workflow, as we are having quite high project throughput. So yes I would not use an effect, or think of a more efficient method to achieve said effect, if it was going to significantly bottleneck the workflow by several orders of magnitude, and yet only added negligible subjective aesthetic improvement.
It comes down to classic "Cost Benefit Analysis", thats why I was asking for technical documentation, to see if there is anything we are doing which is having a big hit on performance, which may have a more efficient alternative or may not improve the quality to a level which warrants to slowdown.

What's the fastest Compression Codec?

I need to make a series of quicktimes for clients to view from my server and don't want to wait hours and hours. Everything is DV, half hour shows, and I would like to make them very small, very quickly so the client can review and approve before I lay to tape. I already feel 15 fps and 320x240 is fine, as well as compressed audio. I know that some codecs take more time per frame than others and if I can smoosh a half hour show in 15 minutes, 10 minutes or something that would be great.

Good luck.
CaptM
Ok, I'll answer this question.
Hey -- mpg4 from compressor is the fastest with highest quality I've found.
But you know what? Take some time for your customers and you might actually get some more in return. h.264 is the best you'll come up with for the megs you'll spend.
Forget the hours. Using Compressor will still give you edit time on FCP too.

Timeline compressed

The timeline in one of my iMovies is all scrunched up to the left side. It's not really a problem when in the viewing mode but when I click on the L icon to work with the audio track it too is so compressed to the left I can not get into it. I have no Idea what caused this as it was fine a couple of months ago. I must have done something but can't remember what.
Thanks

Hello bigdukesix,
below the audio tracks, on the left hand side, there's a slider for setting the "compression" of the timeline. Simply drag it to the right until you have the desired "expansion".
hope this helps

JPEG compression codec in C

Hi guys.. I am trying to write a JPEG compression code in C language. Does any of you have the code already?? Can you pls post it for me? Also, i am trying to compress an image and send it over wireless link. Can i use JPEG or should i use only JPWL??
thanks.

Your inquiry appears to have no relationship to Oracle Database Advanced Compression.
I would suggest you ask it in a forum where it is on-topic.

Timeline Compression Question

Hello,
I am working with footage in a timeline that is HD (1440x1080)(16:9), compressor video setting is HDV 1080i60.
To get a higher level of quality, should I change the compressor setting to ProRes LT within the timeline before I export?
Text, photos, and graphics are part of the project and any help would be great.
Thanks

ProRes LT would make the graphics look better, but it won't improve the quality of the HDV footage. Video quality can't really be improved over the original.

Multiple Codecs in Single Timeline ---Sequence Settings

This has to do with determining the correct sequence setting when using source material that is originally compressed in different codecs, some of which has square pixels, some ntsc "rectangular pixels," many of which are compressed at different fps.
Is it best first to transcode all the source material to a single codec, with a common frame rate and pixel aspect ratio? And, if so, which codec?
A good deal of the material is standard dv 720x480, 29.97 fps.
Should that be the base codec? Should my sequence settings reflect that and have everything else conform to it? Or should I conform everything to something different?
What I'm aiming for is to avoid constant rendering when I bring these different sources into the timeline.
And, more generally speaking, is there a tutorial regarding codecs and mixing them in a single timeline?
Thanks.
david

Is it best first to transcode all the source material to a single codec, with a common frame rate and pixel aspect ratio?
Yes...absolutely.
And, if so, which codec?
ProRes NTSC. Or DV50.
A good deal of the material is standard dv 720x480, 29.97 fps. Should that be the base codec?
No. DV *****...lowest end SD format that is broadcast acceptable. Don't do with the lowest common denominator...go with a GOOD codec. What are the others?

Timeline Codec incorrect?

Hello all
I've been having crashing problems for months in FCP, even after I recently upgraded my O.S. and bought a full new version of it going from the educational one I had previously. So the entire system has been formatted and reinstalled... Yet I still have mind boggling numerous crashes while simply pressing play quite often. I can't barely work without a crash every 2 minutes.
After doing all typical fixes like preference related things, using Disc utilities, etc... I am down to wondering if the timeline format simply doesn't LIKE my video. The thing is, I am using the "native" setting when dealing with the video.
I shoot from 12 to 17 MBPS using my Canon Vixia HG20 (an HD camcorder).... and load it into the timeline as a native format, simply by saying "yes" when it asks me. I have so many crashes when all I am doing is scrolling, or pressing play only, nothing fancy.
I wonder if there is a suggestion as to what timeline codec or other settings I should perhaps try and use instead of the "native" codec that comes up when I drop the video in a sequence. I am currently re-rendering it all by changing the "codec" portion of the timeline settings to "DVCPRO HD 1080p 30" and hoping it will take care of things... But I don't know for sure if this is my best choice... Especially since there are the new Apple intermediate codecs.
Any suggestions? Perhaps my MBPS is causing FCP to choke because it is too much data?

Hello
I think the above information linked to is probably what is going on in this situation... At first I tried to change the codec type used in the edit sequence, and this seemed to help, at least at first... I got another couple of hours in editing in which there were much less crashes going on, so I actually got something accomplished. A couple days in again however, and it seemed that all rules were off... Suddenly I had crashes virtually every few minutes, losing my work as before. Nothing had changed since the previous sessions better work. I also had begun trying to use things like Livetype, and when I imported some video into that as a frame size to work off of, it also crashed though not immediately. I went back to trying to use DIsc warrior to check into file errors a few times in a couple days. I did find errors, but that is unusual to scan a few times hours apart and find errors, except that the crashes probably created them...
It seems like my problem is not application specific (motion and livetype crash when I have the video imported also), but probably more to do with the AVCHD articles you point out... The working codec used in trying to go from this apparently "not natively supported" codec which a lot of cameras use. I would have thought that changing my timeline settings to ProRes and rendering it all would have helped more than it did.
I don't have the flexibility to redigitize as all video was captured from the camera hardrive and then erased from the camera, as I couldn't hold it for long on there (that much). I have no idea how I would edit and then replace the cut video in the timeline with higher res versions later anyway, I've never seen it done. Possibly ensuring that the log and transfer window is using ProRes at the start may help next time. But in this particular situation and job, I must get this finished and still have to cope with all the AVCHD HD video sources used... Then just "changed" via the timeline settings codec.
I can't be 100% sure this is even the actual problem so many crashes have occurred while doing literally anything, even just playing... But it seems to be the best guess. Since I still must complete this project, what I still look into to try and minimize the crashes? I think I only had much in the way of crashes once I used a higher rate of camera quality MBPS... Maybe the computer is just choking on the data rate as much as anything... Even though I am rendered, drag a little in the timeline, or just press play quite often.

Determining which audio channel a timeline clip came from

Hello,
How can you tell whether the source of an audio clip in the timeline came from channel 1 or channel 2 on the master? I've tried Clip Properties but that only shows which timeline track it's in (which is fairly obvious if you've just selected it).
Many thanks!!
-- Sean

Sean, its a very good question that sadly has an hopelessly inadequate answer.
Of course FCP does know exactly which specific channel of audio (from a multi-channel source) that it's referencing, but there's just no easy way of determining which channel that is after the edit has been made. In some situations I can see exactly how and why that would certainly be very useful, just as it would be useful (especially in fast turn around editing) to be able to simply reassign an edit instance's audio source channel after the fact eg to be able to target an audio clip instance and simply switch it's content from say ch1 to ch2 of the source.
As it stands, although it's possible to do this in other NLE's its not yet possible in FCP. As always, you can send feedback to Apple's FCP development team at: http://www.apple.com/feedback/finalcutpro.html
Ok, heres what you can do If its absolutely essential that you correctly identify your edit's audio clip's channel sources: you need to export your sequences as XML files (File > Export > XML). The exported XML will contains the full make up of your edit, including every clip instances audio channel sources. Its not especially human readable but neither is it encrypted, its just a plain text file .... so you can open it up in Text Edit and figure it out.
Cheers
