Fragmented f4v files

Does anyone know if there is some kindof specification of the file format of a fragmented f4v file (ie. f4v file with moof atoms)?
I've got some h264 encoded fragmented mp4 files which work with a smooth streaming (silverlight) player and was hoping they would work with a flash player, with fms 3.5, by just renaming the file extension to f4v. Unfortunately they don't and I can't find any information regarding what atoms fms requires to play fragmented f4v files. This is a file format produced by the current version of Media Live Encoder 3. Also interestingly my fragmented mp4 pass tests run by flvcheck.

Hi,
I figured out what my problem was, it turns out I hadn't set the base data offset in the tfhd box to point at where the video stream starts. Smooth streaming allows this as instead it contains a mfra box at the end of the file which points to where the video stream starts. Now my fragmented mp4 file is playing fine

Conversion of fragmented f4v files

Hi,
I want to convert f4v files. Recorded with adobe's live media encoder. So I can edit them in Premiere Pro or play them with vlc.
Right now the files are 500 mb, the information is in it. Only playback stops after 7-10 minutes.
The following I allready tried.
ffmpeg (does not work, neather windows or linux)
f4vpp (i get the 203 error)
now I want to set up adobe flash media server and record them with stream recording software. Dont get it figured out, how to open the rtpd stream.
I did a default instal, and when I replace the file sample_1500kbs.f4v in the vod folder with my file, it works well. so now I want to find out how to catch the stream..
Any help would be apreciated!
Kind regards,
Vincent Vriens

Hi, victor.
With H264 video format, you can convert from f4v file to mp4 (or other) with ffmpeg. You should check ffmpeg.
I used
<code>
ffmpeg -i filename.f4v -b:v 500k filename.mp4
</code>
and it worked.

How to make Adobe Flash Player the default player for .flv, .f4v files?

I have currently installed from Adobe the following applications:
Adobe Bridge CS6 (64bit)
Adobe Bridge CS6
Adobe Dreamweaver CS6
Adobe Encore CS6
Adobe ExtendScript Toolkit CS6
Adobe Extension Manager CS6
Adobe Fireworks CS6
Adobe Flash Professional CS6
Adobe Illustrator CS6 (64bit)
Adobe InDesign CS6
Adobe Media Encoder CS6
Adobe Photoshop CS6 (64bit)
Adobe Prelude CS6
Adobe Premiere Pro CS6
Adobe SpeedGrade CS6
Adobe Flash Builder is not installed.
Adobe Premiere After Effects is not installed.
I've just downloaded Adobe Flash Player 13, but .flv files and .f4v files are not played by Adobe Flash Player. I've tried to make it default player but i didn't release which file .exe to browse for (by right-clicking and choosing Open with > Choose default program...).

There's a Flash Player Projector (standalone) in the Flash Professional CS6/Players folder, but it's usually outdated.
When browsing to an app to use from the Properties window, go there, but... download this one: Windows Flash Player 13 Projector and replace the Flash Player that's in that folder.
If you're looking to test Flash files you've authored, then you'll need the Projector, but if you're just looking for a good player for FLV and F4V, then you should use VLC Media Player. http://www.videolan.org/

Adobe Media Encoder and f4v files

I have a bunch of f4v files that were created by FMLE 3.2 that I'd like to convert to a more usable format, but when trying to open them in Adobe Media Encoder CS5.5, I get an error that says:
"The file <my file> could not be imported. The source compression type is not supported."
These are f4v files straight from FMLE, with h264 video and aac audio, and they play fine in VLC. This is all running on Mac OS 10.8.
What gives? Can AME really not open f4v files from FMLE?

Apparently not.

FMLE + blackmagic intensity pro : locally saved f4v files are choppy/jerky

Hello,
I'm successfully using the blackmagic intensity pro with FMLE for live streaming.
Unfortunately, although the streaming is perfect, the local f4v files recorded by FMLE during the streaming are not proper : they appear all jerky or choppy. (they are correctly post-processed by f4vpp)
From the strange effect on the video, I'd say the problem seems to be a interlace/progressive confusion in FMLE when recording locally, but why is the stream good...?
I tested both component or composite input of the bmip and it's the same. I've tried all interlacing/progressive settings possible in the BMIP input and on the camera too.
I precise that the same setup is working very well with DV input from the same camera (the purpose is to change for a non-DV camera with BMIP).
Is there somebody who faced that and solved it ?

Using f4v Files in Acrobat 9

Is it possible to play f4V files in Acrobat? Using the flash tool I have included an F4V file but the video will not play. Are there complatibility issues? Any ideas?
Thank You,

Melanie, Did you find a solution to the F4v issue?

How to use F4V Files with Premiere 5.5

Hey all,
I work at a small company that does live streaming of video. We are experimenting with new HD cameras and have found that our best results for streaming has been to use h.264. We are having fantastic results with this, however, Using Flash Meda Live Encoder the end result is an .f4v file. I don't have much experience with this variation of .flv, but I'm honestly finding it quite useless.
I understand that you don't typically edit this type of file, that it is in a sense working backwards. However, our situation is that our streaming quality is highest when we use this format. Obviously, I am unable to get this file into premiere to edit it. I'm actualy unable to play it virtually anywhere as well (moyea converter, moyea flv player, vlc...nothing plays it).
Does anyone have any suggestions as far as where to go from here? I know there is probably a lot more info required for anyone to give me some feedback, so let me know what you need to know about our equipment/settings and I'll supply it.
Thanks for the help!

@Jim Unfortuntaley, it's not practical for us to encode two files, one streaming and one capturing in a different format.
I do appreciate the help though.
@John That program looks cool, however that doesn't help either because we stream LIVE video. So I need to be encoding through FMLE or WME if I'm doing a windows file.
I actually had some progress using the adobe f4v post processor. I was able to convert the file into another f4v file that was able to import into Premiere. However, once I import it, I get no audio on my file. When I play the file, there is audio, but again when I import it into Premiere, no audio at all.
This seems to be a common problem and a potential bug. But if anyone has any further input, im VERY close to having success if I can only get my audio in there. (I do know I could get the audio into premiere by itself, but I'm trying to create a workflow that I can bring to my boss. He won't be a big fan of having many steps to get everything into Adobe)

So I have made a .f4v file in Media Encoder, now what?

Media Encoder's presets are all about making .f4v files rather than .flv files out of video clips, so I figure it is the prefered format, but DW in CS4 seems to have never heard of them. What's up? How am I supposed to use these .f4v files in DW?

Adobe Media Encoder, without warning, embeds a huge iSkySoft logo in the upper left hand corner of every movie I put in the queue. I did find a way around it, though. One must specify Flash 9.0 or above to avoid the un-invited logo embed. Absolutely disappointing. I read in a post that the Encoder is a stand alone added to CS4. Dreamweaver will only accept FLV or FL4 files, and the Media Encoder will supply this, but at a hidden cost. Really, all users must download Flash 9.0 to view my videos without the iSkySoft logo?

CS5 XMP metadata make huge Flash F4V files

In CS4 i had MPEG2 files that I need to export as F4V for preview purposes.
Four MPEG2 files side by side in one long F4V video.
The MPEG2 files are exported from Premiere, with a lot av complicated After Effects Comps as source.
Each MPEG2 file gets a corresponding XMP file that i just ignore.
In CS4 it worked great. The F4V files came out at about 32MB, just as predicted by the encoder before I started.
Now, with the same project in CS5, I did the same process.
Only that the F4V files for some reason came out at about 57MB, with the same settings as before.
I noticed that the corresponding XMP files for the MPEG2s now where 3.5 MB big. Before they used to be 7KB.
Then I deleted the XMP files, and let Premiere generate new ones. These was only 4KB.
I then exported a new F4V, and i came out at 32MB.
So WHY ON EARTH would anyone want to embed 25MB of metadata in a 32MB F4V-file???
A file that will go on the web, and you try to get as small as possible?
And what is all this metadata?? I did not put any thing in there!
4 x 3.5MB does not even add up to 25MB!!

Preloader to also preload external f4v files in main movie?

n00b alert... I did search the forum (and several others
online), but either the code got too complicated for me to even
attempt to adjust it, or I didn't find a relevant answer.
So I really hope someone here can help me out.
I've found a preloader code online that works like a charm. I
don't really know what half of it actually means/does, but it
preloads and then plays the mainfile.swf . Me happy.
But the "mainfile.swf" calls external f4v files, and the
problem is that they do not get preloaded. (And that kinda was why
I needed a preloader in the first place...)
I gave all the f4v files instance names within the mainfile
(assume: video01.f4v, video02.f4v etc), and the f4v files
themselves are in the same folder as the mainfile.swf.
What do I need to add to the code to get it to preload
everything?
Thanks in advance!!
ActionScript Code of my preloader is attached.

You could load each movie using movieClip.loadClip(); and
check it has been loaded by using a listener and the
"myListener.onLoadInit" script to write your own function to begin
the playhead for that movie.

What is a f4v file?

When I export my footage, Elements creates a f4v file, but when I click on it, Windows tells me that it cannot open it.

graverholt
You must be in Publish+Share/Computer/Adobe Flash Video. The F4v file extension is a wrapper format for a flash file.
What Open With are you trying to use for its playback? Please right click the .F4V file, select Open With, and then try the VLC Player, Mozilla Firefox (if it is your default browser), or QuickTime. Does the .F4V open for you with those programs?

Ca'nt ftp longer (i.e. 4 minutes) flv or f4v files (get error message "waiting for server") I

when I ftp(i.e. "put" or "upload) short flv or f4v files using dreamweaver cs4 the files upload easily and quickly. However, when I try to ftp ("put" or "upload" ) longer (i.e. 4 minutes or longer) flv or f4v files it goes through the ftp process (seeing it in background activity screen) but at the end I always get a message "waiting on server" and the longer files don't get onto hosting server. Is there a setting I need to change or other method I need to use). I have worked with my hosting support tech person but we could not solve this problem.

I'd suggest that you try using a dedicated FTP program like Filezilla or SmartFTP.
http://filezilla-project.org/
Those programs give you much more feedback on what's happening as you attempt to upload files, including error messages, etc.
There is really no difference between uploading large files and small files, the process on the server is exactly the same..UNLESS there are limits to file size or video duration set by your host. So dispite the fact that you have worked with your host support, I'd still say that the problem is server side or being limited by your Internet service provider... unless the video files you are attempting to upload are corrupted.
You didn't say if any portion of the larger video files were uploaded...and FTP program will show you whether or not ANY of the file was uploaded and at what point it stopped. You also didn't mention how large the video files where.... sort of where the "tipping point" is in file size (video duration of course is no measure of file size).
Just to reassure you, the file size of a video file will have no bearing on your ability to FTP unless your host or ISP is limiting you in some way.
I regularly Live stream events and also record them. An 8 hr event will produce roughly 1.5GB of compressed video. I use SmartFTP, with a reputable host and can upload the entire set of 1.5GB of video files (each about 50MB) over a 1000kbps upload connection without problem. Recently during a movie production project, we uploaded a number of single video file which each where over 1GB a piece.
So there is really no problem uploading video files unless there are restriction on you account from the host or the ISP.
Best wishes,

Problems playing .f4v files in CS5.5 that were rendered from CS5.5?

Premiere Pro CS5.5 seems to have trouble playing .f4v files that it has rendered? I basically edit my video, (uncompressed .mov) export it as a .f4v file for YouTube which is about half an hour in length. I then get that half an hour video and do a video preview of what happened over the half hour… like a montage. I used to export my videos to .mp4 and I never had any problems when trying to do my montage edits, but now that I am using .f4v CS5.5 freezes the video but the audio keeps playing, the video won't play at all or it freezes during transitions (and the transitions are rendered before I try to playback my clips) The bottom line is that the .f4v format has never played back perfectly once and I could understand this if I had got the file from somewhere else but I rendered it from CS5.5? Can anybody help me with this please.
Thank you
Bird

Hi Jim, thanks for your reply What you have suggested, is what I think I will do. I think I'll create a new sequence from my exisiting sequence and do my montage edits that way instead of using .f4v or .mp4. Do you know why I was able to edit my montages from .mp4 with no problem but not from .f4v file format which was rendered from CS5.5? I just wondered why as this seems odd to me.
Thank you in advance.

Problems with streaming f4v files longer than approximate 1 hour

Hey Everybody!
I have a problem streaming on-demand f4v-files longer than 1 hour! The video starts normaly playing the stream and the player shows the correct overall duration. But if you start skipping/seeking the overall duration change to 13 h 20m and 28s (instead of 1 hour) and the stream breaks down. All f4v files with less than one hour duration works fine with playing and skipping!
I encode the f4v files with Adobe Media Encoder. I have also checked the f4v file with FLVcheck (passed). So, does anybody have an idea in fixing this problem and which format is the best for FMS streaming (MP4, FLV, F4V?)?
Thanks

To complicate this further, I found I wasn't able to output F4v files from Adobe Media Encoder (Premiere Pro CS4), without the file freezing at 1 hour 11 minutes and 34 seconds. I output 5 different 2-hour clips, played them back in Adobe Media Player and all froze exactly (to the second!) at 1 hour 11 minutes and 34 seconds. Found it interesting and inexplicable that this poster had exactly the same issue, but involving software that is completely different - http://forum.videohelp.com/threads/53987-Virtual-Dub-Strange-error-help-needed-ASAP Can anyone make sense of this?
