Web compression

So i have experimented with different compressions....but i would just like to hear what a professional would do.
I have a 16:9 vid that i would like to host on my website at optimum quality. How would u compress this footage?
Aaron

You've answered part of your question in that you know your source is 16:9. So, your target stream will be 16:9 or properly formatted 4:3. There are articles all over the web on how to do this. Now you just need to pick a codec, bit rate, frame rate, and if your source is interlaced, how you are going to make your stream progressive. Quality is subjective, so all of this is up to you. Some of the more used codecs for the web are: H.264, MPEG4, MPEG1, Flash, and WMV. The choices are yours.

What is the best web compression ?

Hi all web compression experts,
I have been trying to find out what is the optimum settings for files to be downloaded on the facebook. The limit I set is 100MB.
But when i rendered my 6.5 mins video in FCE, the filesize for the .mov file is a whopping 1.8GB. After much trial & error, I follow Diana's instruction in her Apple Pro Training book. Below is the summary of the steps she taught me in her book:
Video:
Compression: MPEG-4 Video
Frame Rate: 15 fps
Keyframe: 5
Data Field Rate: 700 kbits/s
Quality: Best
Size:
Dimension: Custom; I typed in 480 x 270
Sound:
Format: AAC
Channel: Stereo
Rate: 32 kHz
DESELECT prepare for Internet Streaming.
With the above settings, my file size has been reduced to 35MB. So I can still afford to add another 65MB before it reach 100MB. I tried to change the compression to H.264 but whenever this option is chosen, the file reach 400MB and took ages to render.
I have also change to the frame rate to 25 fps but there is no difference in the filesize & picture quality.
Can someone be kind enough to gimme some tips on what the numbers in the setting "Keyframe: 5" & "Data Field Rate: 700 kbits/s" do to the video ?
Is keyframe 5 better than keyframe 10 ?
Any suggestion?

Hi again Ryan,
I just got very good results exporting as suggested by Vimeo in this link:
http://vimeo.com/help/compression
Format: Quicktime Movie
Codec for video: H.264
Frame-rate: Current
Keyframes: Every 30 frames
Data rate: 5000 kbits/s
Size: 1280x720
De-interlace: Yes
Sound codec: AAC
Sound Sample Rate: 44.1kHz
Audio Quality: 128kbps
I didn't see much reduction in quality, and it reduced a 457MB file to 19MB. Judging by my calculations, if a 457MB file was reduced to 19MB, a 1.8GB file should be reduced to 72MB. Something to try perhaps?
Thanks skalicki`& dpapa,
I tried the above settings but it took ages to render. When it reached 45 mins, I gave up. By & large, whenever I use H.264 it takes very long to render !

Audio output levels for web compression...

What is the highest db setting to use when outputting from Premiere. I just started using it and I did a few test for web compression and the audio seemed low.
I tried some material that I had editied in FCP and setting the same levels for output and it gave me different results.
What is highest we should go at peak level? -3.
Worked with FCP and Soundtrack Pro so I kinda have a system worked mixing audio. Just need to transfer to Premiere.
Thanks in advance

Already, you have gotten three answers, expressing three personal choices. They are somewhat close, but each differs by the editor.
I am glad that you are asking, because one of my really big pet-peeves is to find a tutorial, that I really want to view, only to have an ad, that runs before the tutorial hit at about +6dB above the Audio levels of the tutorial (like ads on many TV broadcasts), and I have to quickly attenuate the Volume, only to have to ride the Volume up, to hear that tutorial. This can be really painful, if I am working with my headphones on.
Though not directly related to your specific question, I find that most DVD's, and BD's have the Intro, and Menu Audio set too loud. When doing authoring, I attenuate the Audio for both down, to slightly below the Levels of the actual disc. I want those to be "background" only, and never want users running for the Volume control.
Good luck, and hope that you do find a "sweet spot," that works for your material.

HD for web compression problem

I'm trying to compress some HD footage shot on an HVX200 for the web and am having a problem with jagged edges. I'm somewhat new to HD, but this problem resembles interlacing artifacts from my previous DV days. Straight lines aren't straight, they're jagged and the edges around people with white shirts on dark backgrounds have a similar jagged/digital characteristic. Here's how my project is set up.
Shot on HVX200 at 24pn. Edited in FCP and my sequence settings are 960X720 HD (16:9) frame size. Pixel Aspect Ratio of HD (960X720) and QuickTime Video Settings set to Compressor: DVCPRO HD 720p60 at 100% quality.
When I save a self-contained quicktime movie like this and view it on my monitor, no jagged edges. It looks exactly as I'd like it to look after its compressed. However, when I pull it into compressor and try to encode it with h.264, it comes out with the jagged edges. I have the following settings in my Compressor summary:
Format: QT
Width: 480
Height: 360
Pixel Aspect Ratio: Square
Field Output: Same as source
Frame Controls On (Retiming: Fast, Resize filter: linear filter, deinterlace filter: best)
I've tried what feels like all of the various combinations of sequence and compressor settings. Obviously, I've not tried them all. How would I render this out for high quality web display?

Compressing as mp4 instead, I was able to get this to work tweaking some of the settings in there. Only problem now is an enormous file size that I have to work to get down, but whatever my issue was, seems to have been corrected.

Web compression in FCP

Hello,
We are trying to compress h264 movies for playback off a site at 480 and 720 resolutions ... what settings in FCP or QuickTime pro would be best for fastest playback and best picture?
Thanks in advance for any help!

BTW, here is a screenshot of our settings we are using so far:

New web compression techniques?

Years back I bought Sorenson Squeeze v3. I used it to make .movs and .swfs in multiple sizes. It immediately bought the quality of my online presentations much higher.
About 2 years ago, I purchased FInal Cut Studio and began using h.264 in Compressor instead of .mov's with Squeeze.
I just updated all my applications. FCS2, Flash CS3, etc. I'm wondering now if I can also update my compression techniques.
I looked at On2 VP6 about a year ago, and liked it, but wasnt affected enough to buy.
What's the latest and greatest out there? What are the big boys using now? Is there anything on the horizon that I should be waiting for with Flash CS3 freshly released?
Any insight would be greatly appreciated.

I think the choices are between Flash, and QT H.264... Flash because it's on every computer in the world and is a lot better than the MS solutions, and H.264, because I think it looks the best of all at any given data rate.

Properties: Metadata: Print or Web?

What is the difference in choosing Advanced Metadata, either Print or Web?
The documents we are working with will become downloadable digital content. Does either Print or Web place restrictions on a document, or does the choice of Web compress it?
Thank you!

Thanks for that everyone you were right! I was being super-DUper sMart and Brilliant there and had only been trying to re-arrange within the layout window of the Print and Web areas. I think I was just assuming I was having the same trouble from Lightroom 1 and just stopped trying since it seemed the files either never moved or didn't stick (can't remember now). In any case, Thank you!

Sending material to be compressed

Hi all,
Have searched but nothing I could see precisely relevant. My web guy has asked for me to send a QT file to him so they can compress a short promo I made and pop it on their website. Is it as simple as taking the saved QT file (not movie) and dragging onto a disc or am I just dreamin' it's that easy?? Have never had to do it before.
Thanks for your help in advance.
J

I asked some questions. Could you answer them? What format are you working in? Are you doing the web compression or is the web guy? What platform is he using, Mac or Windows or Linux? The best quality is to export a QuickTime Movie if the web guy is doing all the work. But that may not work if the platform is wrong and the format you're working in is wrong.

Having problem with FCP 5.1.4 adding transitions. Just new to this app.

So I get 2 maybe 3 transitions set correct. After that none work properly. ie: lets go for the quicktime zoom transition. So as it zooms out it plays the first quarter of the 1st part of the transition in the zoom box. This is not correct it should be playing the second part of the transition. Anyway about 1/4 of the way through it does play the second half of the transition which is correct and plays the rest of it properly. It does the same for cross dissolve and all other transitions. I have trashed the preferences but that doesn't seem to help. I have also changed the preferences and that doesn't help. OS is 10.5.8; 6g of ram; powermac g5 quad core 2.5ghz;
Please if anyone can help.
Below I entered FCP 6 because 5 was not available.

Just to clarify, by "FCP 5 friendly source material," he means video files that are a format (codec) that FCP 5 supports. What FCP 5 supports can be found in the EASY SETUP list. If the format you are working with isn't there, say if your footage is H.264 or MP4 or some other web compressed format, FCP won't work properly. It needs to be in an editing codec if you want FCP 5 to work with it.
Also, you need to make sure that your sequence settings match the settings of the footage you are trying to edit. If you add a clip to the sequence, and immediately have to render, that's a big clue to say that something isn't right. You should edit without rendering at all.
The most important thing you need to do is properly set up your project from the start, and the best way to do this is to choose a setting from the Easy Setups, located under the Final Cut Pro menu. Once you do this, you’ll need to create a new sequence. This is because the sequence that is already in your new project is setup for the typical default setting of DV/NTSC, or for the settings of your last project, which might not match what you are currently working with. So delete SEQUENCE 1 and create a new sequence:
This new sequence will contain the settings you chose in the Easy Setup menu, and should match the format you captured

Dreamweaver 8

I'm a designer. I work a lot with CSS so I'm constantly
previewing minor changes in my browser. I get the prompt when I go
back to DW8, "This file has been modified outside of
Dreamweaver.... blah, blah, blah." I almost always say no. When I
say yes after previewing my page in IE7 there is bunch of garbage
code added to my code. Usually fragments of code from the same page
that I've deleted or portions of the existing code. Any of you
experience this?

Any compressed codec video will work - the web authoring application is irrelevant. Try H.264, Sorenson, or MPEG4. In FCP, go File > Export using Quicktime Compression, and choose your format. Web compression is a black art, so you should do some learning first.

Media Encoder adding RBG color casts on BW 16mm Footage

Hey Everyone,
I am really stumped by this one. I am working with FCP6 and Apple Pro Res HQ scans of 16mm B&W footage. I am trying to encode a self-contained .mov file (direct from FCP) in Adobe Media Encoder CC (for Blu-ray) and then burn to Blu-ray with Encore CS6.
I burned the first test Blu-ray last night and when I played it back on my Blu-ray player/TV, I was stunned by the fidelity and definition of the otherwise thick/complicated 16mm grain structure, even via what was only a 6GB .m4v render (compressed from 33.5GB .mov). Everything was perfect...EXCEPT...I got these horrible "color casts" of red, blue, green, magenta, across practically every shot in the footage. Particularly in the last shot of the drain pipe (see example clips 14 seconds long):
Original: https://vimeo.com/97456916 (pass: "original")
Blu-ray: https://vimeo.com/97453674 (pass: "colorcast")
Obviously the footage does not look this in either FCP6 or .mov in QT7. I just double checked and the color casts ARE visible when playing back the ME converted .m4v in Encore. I have also taken the .mov from FCP and brought that into Encore and NO COLORCASTS. I have also taken the .mov, reimported it to FCP and but a 3-Way Color Corrector on it and put the saturation at zero, exported that, and then ME>Encore and it still adds the color....So I am 99% positive this is a Media Encoder issue. Here are the settings I used:
Considering how long is has taken me to get satisfactory web compression results from 16mm footage in the past, I feel like I just hit a grand slam in the bottom of the 9th with the playback fidelity of the first test Blu-ray. The motion and definition are phenomenal, I mean we are talking Criterion quality--without X.264 or Blu Code--(even with all the modern "overcompensation" crap turned off on my TV). I AM SO SO CLOSE TO RENDERING/BURNING A PERFECT BLU-RAY IF I CAN JUST FIGURE THIS COLOR THING OUT!
Got a deadline to get this into the hands of a couple of prominent filmmakers.
Any help or ideas that anyone can provide will be most appreciated.
Thank so much!

***SOLUTION***
Well it seems silly that I had to do this at all, but here is the workflow that finally seemed to solve the issue without adding an extra level of encoding...
Save self-contained .mov of my timeline in FCP6 > bring that back in FCP as a separate sequence and apply the "Desaturate" filter (Image Control > Desaturate) to the entire film > save as self-contained .mov again > convert in AME > master and burn to Blu-ray with Encore > Presto!!! NO COLORCASTS on B&W 16mm footage in Encore and no colorcasts from the file on the burned Blu-ray disc.
I believe I stated it above, but in case I didn't, adjusting the chroma and/or "desaturating" via FCP's color corrector plugins did not work...even with the exact same workflow otherwise. I have no idea why, but if anyone ever runs into the same problem, this worked for me. Only took two weeks to do something that I guessed would take a day, maybe two. Geesh.
Thanks again guys for all the suggestions. Really really appreciate it.

Adobe Media Encoder FLV issue

I am posting this question here because there is no Adobe Media Encoder forum - sorry! My question is about file sizes. I created some videos in Premiere CS4. I need to convert the videos to FLV formats (they are to be used in an e-learning module that requires FLV files). However, I'm having trouble with the file sizes. At the rate it's going, I will max out our server space in no time.
To give an example, I have a 17 second video with an original frame size of around 720 x 480. When exported as a MOV file (high quality, etc.) it's about 66MB. I've tried creating the FLV straight from the Premiere project file, as well as separately, by running the MOV through Adobe Media Encoder and the results are just about the same. In either case, I can't get the file size anywhere below 1.8MB, which seems rather large for a web compressed 17 second video. The file size DOES NOT get smaller when rendering at the smaller frame size of about 300 x 220. Back when I used to use Sorenson Squeeze for web compression, changing the frame size like that would usually cut the video file size in half. Media Encoder leaves the file size the same...
I hadn't worked with video in a little while, so Adobe Media Encoder is new to me... but I asked my husband about this. He's a web developer and deals with video a lot. He said that he would take a MOV file, drop it into Flash Video Encoder and use the preset for FLV and it works great - a video that's this long should only be about a few hundred k in size (it's not a complicated/lots of transition video). Apparently Adobe Media Encoder has replaced Flash Video Encoder, so I don't have the option of trying it the other way... has anyone else run into this, and if so, do you have any tips?
Thanks so much!

I'm having a similiar issue, my file orginally is only 10sec long and 13mb *.mpg file, the same as it was when I was converting in CS4, only back then, the convertion took maybe a minute and the output file size was about 1mb or smaller, and that was keeping the 640x480 size and removing audio. Now with CS5, the estimated output size is anywhere from 2000-3000mb for starts, remove audio and scale back other settings and I can get it down to 70mb and takes a staggering 2.5hrs to complete...for a 10sec video. I don't know what they changed between cs4 and 5 but they screwed up big time, this is a joke. i'm on AME ver. 5.5.1.12(64-bit) if that makes any difference. any idea or help would be greatly appreciated, I've got about 5 of these 10sec vids to convert a month and I need to get this fixed.

Photoshop Layers to Fireworks Layers

So I just downloaded Fireworks CS6. I have not used Fireworks in a few years, but I was hoping integration with Photoshop was much smoother by now.
I have a PSD with a background and about 50 text layers that I want to open in Fireworks so that I can export each layer individually along with the background and use save for web compression. Sadly, Photoshop does not allow either of those things in its export layers to files script.
However, when I open my PSD in Fireworks, the layers do not come in as layers, they come in as SUBlayers. This is quite baffling to me. Why on earth would Adobe program such nonsense? If I open a PSD in Fireworks why would I want Photoshop layer to EVER be brought in as sublayers unless I actually put them in a layer group in Photoshop?
So then I looked for an option in Fireworks to make all sublayers into individual layers, but I could see no way of doing this. Can anyone please help me figure this out.

I can understand your missing ImageReady; that seems to be a thread that pops up with some regularity.
But I've got a tip for you: Be sure that everything in your original Photoshop file is grouped. Period. If anything is not in a group, then assign it to one. If you do this, the file will open in Fireworks as a series of layers instead of as a series of sublayers.
Keep in mind a few key differences between Photoshop and Fireworks. Photoshop uses a "layer" model where "groups" (i.e., folders) are optional; Fireworks uses an "object" model where "layers" (i.e., folders) are required. If you have no groups in your Photoshop document, it'll import into a single default layer in Fireworks. Add a few groups to your Photoshop document, but leave a few things ungrouped, and Fireworks will still require a layer to contain those ungrouped items, hence the introduction of sublayers to accomodate the existing groups.

Best way to get an .avi file out of a Final Cut Project

Should I export it from the Timeline as an .avi, if so what compressor and settings should I use?
Should I export it as a Quicktime movie and convert it to .avi from MPeg Streamclip, if so, what compressor and settings should I use for best effect?
(note: I have tried one of each, for some reason the Streamclip one came without audio and the one I exported from FCP turned out really pixillated with poor quality.)
Big thanks for any help

Use Export from within fcp>QuickTime conversion.
Choose Windows Media from the format.
Configure from there.
Most likely the standard settings will be good enough - watch the size choice tho' - if you want web sized stuff you have to tell it.
Otherwise it'll give you web compression on your full frame size. You might not want that ..
