Hardware to speed up flv encoding?

Hello,
Has anyone had any experience with a card that will speed up
the conversion from DVD (.VOB) to .FLV? I have to convert hundreds
of hours of video, and am looking for a non-software way of
speeding this up. I am using a Windows-based PC, btw.
Any help appreciated. Thanks.

Do a search on this forum and the web in general. This has been discussed to death just like when to use MP rendering or not. We had 2 similar threads just last week. AE is still a CPU centric app and for "regular rendering" all the fancy GPU stuff doesn't matter one way or the other, especially with legacy CoDecs liek QT Animation or whatever...

Flv encoding software in flex and AIR

Hi,
I want to create an FLV encoding software which takes various
video files and encode them into flv format. Is there any
actionscript library or flv sdk for this? I saw the flash media
server but it is for online apps. I want to create an AIR app which
uses the local storage of the user.
Thanks,
Gaurav

The best bet you have is porting the ffmpeg library to actionscript via Alchemy. Otherwise, there is no library availble for client side video conversion.... that I know of...

Need COTS Analog Speed Signal from Encoder

Hello everyone, need some shopping help.
I have a customer who wants to get a scaled analog output corresponding to rotational speed from an encoder instead of doing traditional freq measurements. We want a stand alone package that does the frequency measurement on board and just puts out a scaled analog output.
Need < 100 mS latency and ability to resolve 5 rpm to 1000 rpm. Just don't know where to go to buy one.
Anyone know of such a device?
Thanks

One example of many manufacturers of frequency to voltage converters:

Look at the detailed specs to make sure the unit's input voltage range is compatible with the encoder along with the response time.

Speeding up DV-encoding

I just got a new 8-core MacPro. Unfortunally it seems as if the threads are not properly allotted, when FCP or compressor is rendering or encoding.
When I am rendering DV or encoding into wmv or mpeg the CPUs don´t run with the entire capacity (diskutility / or istat nano).
Is there any way to speed up the encoding process??? Or can I tell the system somehow, that all of the CPU power can be used for this process? - I don´t need to work with other applications while encoding...
Or do I have to wait for 10.5 ???
Thanks

Have you tried setting up Virtual Clusters? I have tried using them for encoding video to m2v and it helps, though I have had a couple of hiccups

A suitable FLV encoding equivelant for FCP

My web designer wishes to post undownloadable video streams on a website, he asked for FLV files similar to Youtube, he also said he can create a round shaped screen to house these streams.
I think FLV encoding is available on Adobe Premiere, can anyone suggest an equivelant on FCP?

Flash is Adobe's product, not Apple's.
So there isn't an equivalent on FCP.
However, there are several Mac flash encoders available on the internet
Just do a search and you'll find a bunch

FLV encoder crashes on all .WMV files

When trying to view the settings or start que on any .wmv (windows Media Video) file I drag into the flash video encoder, the program immediately crashes. I've tried many different WMV files from different sources, all the same outcome.
Is this a known issue with FLV encoder or something wrong on my end? Hopefully I dont need to buy a 3rd party converter.
Thanks for any insight!

Did you try file - import - import video? That's what I just did with this wmv http://www.charliegooddog.org/pinky/petOfWeek.html it worked for me that's with cs3.

Why is the flv encoder so slow?

I have a quad core q9450 that runs everything quite nicely and I can encode divX quite fast, but processing a .flv file even at fairly low rates (i.e. 320x240) is very slow. Is there a patch or something that is coming out that will allow it to utilize all processors and encode faster?

Is it slow compared to other devices.. ??
Give numbers.. cannot operate from general comments.
Is this 2.4ghz.. are you splitting the load over 2.4ghz and 5ghz??
Have you tried using SMB names.. short no spaces pure alphanumeric, with different name for 5ghz.
Lock the wireless channel for 2.4ghz and test 1, 6, 11 in turn.
Using WPA2 personal security only.. with 8-12 character passkey.. pure alphanumeric of course.

FLV encoding from FCP?

Any tips for software (not too expensive) for encoding FLV direct from FCP or Quicktime?

Nah - but with QuickTime Reference it is almost the same thing... Any reason why you are trying to stay in FCP? I encode all day and usually try and get out of FCP for encoding via QuickTime reference... Not only does it bypass tying up FCP (in version 6 or below) but I have less issues with the encodes.
I had another thought - Make something like this: H.264 Main Profile, 5 Mbps max., 1280×720 max., 30 fps max. Audio: AAC-LC, stereo, 128 Kbps, 48 kHz. Then change its file extension to FLV.
See what happens.

Encoding Speed with Media Encoder Issue?

I have a 5 hour and 36 minute timeline in Premiere Pro CS5 which is composed of mixed assets- some at 29.97, some at 30 FPS, etc. The timeline is exported to Media Encoder and set for Match Source Attributes Highest Quality (Quality 5.0, VBR 2 pass, min 3.00, target 6.00, Max 7.00 MBPS). NTSC 720 X 480 (0.9091), 29.97 FPS, PCM 48hz, 16 BIT stereo. Format is MPEG2 DVD.
Estimated file size is 18138 MB. The file takes approximately 36 hours to encode. Is this normal?
Premiere Pro CS5
Media Encoder CS5
Windows 7 64 BIT
2.4 GHZ
Intel Quad 4
700 GB free space on hard drive
6 GB RAM

Is this normal?
Probably yes. Aside from the normal conversion with 2 pass VBR, which even under ideal conditions could require up to 3 times the duration of the footage (in your case this makes about 15 hours), you are causing additional operations to conform the frame rates on the Premiere level of things. Also, since this is handled as a Dynamic Link process, you may be a bit short on RAM, which may slow down things further. And then of course the usual with disk speed and file I/O etc.. So it more or less sounds normal, but you should not let the initial rough guesstimates discourage you. Many times these values will get much lower after a while of transcoding when the encoder has a much clearer picture and statistical data about how long it actualyl takes to encode so and so many frames...

Speeding up DVD encoding time in Compressor 4?

Hello there, I wonder if anyone can help - I am transferring some camcorder tapes to DVD on my 2010 Mac Pro. My hardware captures in many formats but not mpeg 2. As this is the encoding used for DVDs I presumed Compressor would be quicker to convert mpeg2 files to DVD than say mp4's (?). So I bought an mpeg 2 capture device specially. I then crop, trim the mpeg 2 files in Compressor and convert to DVD but it still takes ages? Is it because I have added edits and crops that it has to be re-encode to a completely new mpeg 2 file or is that just what compressor does to mpeg 2 files anyway? I seem to remember Toast converting an mpeg 2 file to DVD really quickly in the past when there was no editing or changes.
So in summary does anyone know if there is no advantage using mpeg 2 files when editing and converting to DVD in compressor, if not what format would be best? I presume uncompressed DV files might be better.
Any help much appreciated!
cheers

Okay thanks for the reply, that is actually a pretty good way to explain i! Am I right that if there was no edits, a dvd would encode quicker using an mpeg 2 file as source?
Don't know, never have used this workflow. Maybe someone else can answer.
I presume I used an mpeg 2 file and just cropped the last 2 minutes off the end it would again need to be re-encoded?
Yes, AFAIK. Make any change and my understanding is that the mpeg GOP (Group Of Pictures) will need to be rebuilt for the file.
My other capture device captures in mp4, so guess I will just import it direct into compressor and do any edits there, as no advantage using mpeg 2 capture.
Using compressor to trim the clips is, I guess, OK. mp4 is a much newer codec the mpeg2 so may be a better solution for your workflow. If I had the option of capturing in mpeg 2 or mp4, I'd choose mp4.
But keep checking back as someone who has more experience with may be able to give better advice.
When I wanted to move years of home DV tapes to DVD, I bought a set top DVD Recorder from Panasonic and just hooked up the camera and went directly to the DVD, pausing the recording to edit out the stuff I didn't want.

CS3 FLV Encode - Metadata "undefined"

Hey all -
I've recently picked up flash again after a few years, and
I'm trying to work with FLVs. I've been using the "import video"
command in CS3 to encode the FLV files; it's been working great up
until now when my video payer swfs have been hard-wired. However,
now I would like to get into the nitty gritty and create a more
dynamic player.
My problem seems to be that CS3 is not encoding metadata into
the files. I started trying to get videoheight/videowidth, but when
i trace the whole metadata it's undefined,undefined,undefined et
al. I've seen tools on the internet to view/insert metadata, but
they're all PC programs and I'm stuck on a mac here.
Is this something about the new flv implementation? Has
anyone else had this problem?
Thanks so much!

Speeding up the encoding process

I just encoded a 2hr movie which took some time. after reading through some old posts i have not come up with a specific way to increase encoding speed. one suggestion was to use 2 hard drives. how do i set up IDVD to do this? I have an external drive. Will this actual increase the speed?

Have to agree with PT on this one. Almost entirely dependent on clock speed and cpu type.
I'm not sure if additional HD's will increase speed or not. From my own experiences, External HD's may even slow things down a bit. Much better to work from the main internal HD (that has plenty of available HD space) in my opinion. iDVD6 needs plenty of elbow room on the main drive.
If you don't have plenty of available HD space then it could (and in most cases does) slow the entire encoding process significantly.

FLV encoding headaches continue

Let me start by saying I'm so tired of dealing with the hit
or miss, black magic nature of encoding to FLV that I'm considering
redoing a video heavy website in a non-Flash format. Why is it so
ridiculously easy to encode a Quicktime to any one of a dozen
settings, while FLV's remain a mystery to even the most experienced
web and video people?
Here's my problem, I'm encoding an uncompressed Quicktime to
FLV for a website. These are showreel pieces so they have to be top
quality. This is my 8th time out doing this, I long ago gave up
trying to do the encoding myself and have had numerous very
qualified people give it a go with only mediocre results. I finally
found someone who deals with web video encoding for a living and he
gave it a shot and got satisfactory results (no where near as nice
looking as even a compressed Quicktime, but good enough.)
I'm trying to add another video to the site and this time we
can't get it to even an acceptable level. The source was an
uncompressed QT out of FCP, roughly 3BG's that looked perfect. The
video has a lot of handheld camera work and now the FLV has a ton
of striation every time the camera moves, i.e. it looks like the
video fields are out of alignment.
Anyone have any idea how to fix this? I'd be curious to hear
what FME settings people have had good results with, and/or if
there are certain Quicktime settings that cause a problem when
encoding. It seems like everyone I've met who deals with FME
regards it as temperamental and not the best quality, but the only
choice out there. What do you guys think?
Thanks

Hardware or software based menu encoding?

Under DVDSP preferences, under Menu options, how do I know which is preferable, hardware or software based encoding. Can someone please explain the difference?
Thank you.

Pamela:
how do I know which is preferable, hardware or software based encoding.
That depends on your graphic board (GPU) configuration. If you have a slow/old GPU board, you better start using software based and check results. Ussually that must work fine.
Under certain combinations of FCS + OS + GPU, changing from one to the enother settings have solved some weird encoding issues (missing fonts, images, ...) to some users.
But remember that those settings only affect Menu elements encoding, not your video tracks encoding.
Hope that helps !

FLV encoding

I want to have video on my website by allowing the users to
upload their own videos to the site. Right now we are allowing
upload of .avi and .mpeg files using the embed tag. The problem
with this method is that it is incompatible with most browsers
namely mozilla. It seems to work ok with IE but not any others. My
question is this, can FMS encode different video file formats like
.avi, .mpeg, .mov etc into .flv on the fly during upload or do I
have to encode them myself and then re upload them to the
server?

FMS cannot transcode video.
If you want to automate the conversion process, look into on2
flix engine or FFMPEG.
