FrameAccess.java: Modifying frame rate capture ?
I'm currently supposed to capture the keyframes in a video and I've managed to find FrameAccess.java that has allowed me to capture all the frames in the video.
However, I do not need to capture every single frame; just need to capture frames maybe every 20 seconds or so.
-> Therefore, how do I go about doing it?
Also, when I ran FrameAccess.java, it seems that when it has reached the end of the video, it will keep trying to capture the last frame and it won't end until I manually end it.
-> How do I rectify this error?
I really hope someone can help. Thanks in advanced.

However, I do not need to capture every single frame; just need to capture frames maybe every 20 seconds or so. You can grab the frames using FrameGrabbingControl. Then why use FrameAccess.java??
If you use FrameGrabbingControl, then using Timer you can grab frames at whatever interval you want, e.g. try the following code:
[http://forums.sun.com/thread.jspa?messageID=10595229#10595229]
It uses a timer to grab frames at 30ms (you can make it 1000ms or anything by changing this line : " timer = new Timer(30, this);" ).
Now, I don't know what you want to do after capturing images, do you want to save images only or do you want to make a video from this, if this is the case then you can search for "Jpeg to Movie" JMF program example on this site.
Also, when I ran FrameAccess.java, it seems that when it has reached the end of the video, it will keep trying to capture the last frame and it won't end until I manually end it. For me, there is no such problem. The program ends when the end of video file is reached.
Thanks!

Non-interactive FrameAccess.java and frame conversion woes
Hello all,
I am searching for a way to convert a webcam-acquired AVI file into a sequence of numbered TIFF images (one for each movie frame). While searching the 'net, I ran into the well-known sample called FrameAccess.java. Although it looks like a good starting point, I got stuck by a number of problems:
1) I'm not interested in visualizing the frames as they get processed: I've got tons of players I can check the movie with before feeding it in to my extractor. A simple non-interactive application would be better. However, when I comment out the AWT-related portions of FrameAccess, it hangs after processing two or three frames.
2) Which way is better to process the single frame with: PreAccess or PostAccess?
2.1) In PreAccess it looks like the frame is still in raw YUV420 format, whereas in PostAccess it seems to have undergone some conversion since the buffer size is equal to the number of pixels. But the buffer data is returned as short[] when I would expect it to be of type byte[]. What am I missing here?
3) Although it is a priori known that the AVI files were acquired in B/W mode, it looks like the AVI is made of 8-bit RGB frames. How can I possibly convert them into 8-bit or 16-bit grayscale images and save them as TIFF images? (*)
Any ideas/hints/suggestions whatsoever that might help me tackle the above problems will be highly valued.
Thanks in advance,
Emmanuele

Modified frame rate properties keep resetting
Hi community.
I have faithfully switched over to Premiere Pro CC and so far so good. One thing that just sucks is that if I modify the frame rate of a clip (or series of clips) in a project (like take gopro 60fps footage and modify it to playback at 23.976) if I move that project to another computer the original settings come back (60fps)
To better explain, I have duplicate projects set up at home, and in my office. They are cloned projects, so every byte is the same (folder structure included). If I work at home, then take the premiere pro project into to work, and relink it to the media files there, all the modified clips revert back. Which is a pain because I have to go through all the footage and re-modify them.
Any fix on the horizon?
Thanks team!
RsThey are just looking past this, Just make sure to modify all the clips so when your project moves and it resets you only need to modify all the clips at once. Only fix I can see right now.

Frameaccess.java - time of presentation of each frame
i've found frameaccess, which introduces a plugin in transcoding phase of processing.my question are, (i'm a newbie of jmf) it's possibile to modify in the code below the processor to have in shell display,time of presentation of each frame?another question is :it's possible to modify framerate and bit x pixel of output?
thanks

It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for. -
Hi,
I'm trying to conform a movie from recapture, and I'm with troubles.
I'm capturing from HDCAM 1080i 59.94 and after capture my material should be 29.97fps. But always is different.
Sometimes is 29.95 or 28.54 well... severals differents values.
I see the speed of image is OK, I haven't drops.
But when go to conform the timecodes doesn't match.
FCP shows correct frame rate on Bin, but QT shows these variables frame rates.
Anothers programs as Autodesk Smoke and Assimilate Scratch recognize the wrong frame rate too.
I have a Mac Pro 12 core, using the latest Snow Leopard, FCP Studio 3 and QT.
For storage have a External SAS disk array with 32 TB wich has a sustainted througput of 700MB/s (fully tested and OK).
For capture I'm using a Aja Kona 3.
Actually I already saw this problem in anothers versions of FCP and anothers machines.. but I never get to fix it.
Please, someone already had this problem and fix it?
Thanks in advance.
Thiago CabralQT almost is always wrong. It plays what it can... and with Snow Leopard, QT X is just worse. The fact that Smoke and Scratch report the wrong frame rate is really puzzling. Try this...use the CONFORM option in Cinema Tools to conform the footage to 29.97. Might be just the thing needed to LOCK that frame rate still.

Capture HDV Disk requirements for HDV 60i Frame Rate
As a general rule, how much disk space is needed to capture HDV recorded in 60i mode which is 60fps interlaced (same as TV signal) frame rate? Any clues appreciated. Thank you.
iMac 1.83Ghz Intel Core Duo Mac OS X (10.4.8) Canon XLH1 HDV CamcorderMatthew just posted in another topic that 1hr of HDV video uses about 22GB of storage space.
(..1hr of standard def DV needs about 13GB of storage..) -
If I "modify" a clips frame rate is this a permanent alteration, as in Apple Cinema Tool?
I have some footage shot at 59.97 FPS and need to interpret the frame rate at 23.98. If I do this via the "modify, interpret footage" menu options, will this permanently alter the clip? In Apple Cinema Tools, it permanently alters the footage.
Thanks!
EdIt doesn't affect the original media.

Frame rate goes from 24fps to 29fps after capture
I have all my footage on 24fps, DVX100A Panasonic Camera, and work on final cut pro 4.5. After my footage is capture some of the clips are on 29fps and others on 24fps... I don't know why is this happening... When I open the clips on Quicktime, even the ones that FCP has listed as the 29fps ones, the info quicktime displays says they are 23.98fps. I exported those files directly from the capture scratch folder and they go 29fps and if i drag them to the timeline they need to be renderize. I closed the program, re-opened it hoping for some magic but nothing... any ideas?? I'm on a deadline...
did you shoot 24p or 24pA. if you shot 24p you need to capture using the cinema tools preset for reverse telecine. if you shot 24pA, use the setting for advanced pulldown removal.
as well, make very sure that you edit in a 23.98 timeline, not a 24 timeline. You will absolutely lose sync if you edit 24p material in a 24 timeline.
Keep in mind that whether you shoot 24p or 24pA, you are still capturing images into the camera at 29.97fps. The 2:3:3:2 pulldown and the 3:2 (2:3:2:3) pulldown methods are a way of duplicating fields to make up for the 6 frame difference.
i.e. do the count.
Frame 1 has two fields. Frame 2 has 3 fields, one field will be discarded upon pulldown removal. if you are shooting 24pA then frame 3 will also have 3 fields and then frame 4 will have 2 fields. If shooting 24p, then frame 3 will have 2 fields and frame 4 will have 3 fields. If you do the math you'll see that, for your intended 24 frames you have 12 extra fields. That is 6 frames (2 fields per frame...) The pulldown removal removes these frames upon capture. Leaving you with 23.98 frames to edit with. Make sure you use a 23.98 timeline. The setting you changed in your preferences was for playback, since FCP assumes you are playing back to an NTSC CRT monitor (capable of playing 29.97 fps ONLY) FCP will add a pulldown for the output. THis does not affect your project. It is done on the fly by FCP.
Hope this helps.

How to do implement the FrameAccess.java code in my project
Iam doing an project in java for inserting the videos into oracle9i and searching the inserted videos using the frames of the videos inserted.I have done the project to insert and search the videos.But i have been asked to put an EXTRACT button to extract all the frames of the video being inserted.Please help me to implement the FrameAccess.java coding in my existing coding.I have pasted my coding(VideoInsert.java) and FrameAccess.java(used to extract frames) coding.
The VideoInsert.java when executed will contain browse button to choose the video file(only .mpg files) to be inserted into the database.After selecting the file and when we press open button in the Open dialog box,the video will be played in jmf player in a separate window and the filepath of the video will be included in the textbox.Now what i need is,an extract button should be placed and when it is clicked,the frames of the corresponding selected video has to be extracted in the location where the project files are stored i.e.,the FrameAccess.java coding has to be executed.
Please help me if anyone knows how to implement the above concept.

Importing video Frame Rate Off???
I am importing video which was shot on a DVX 100 at 24p the image plays fine on my playback deck but when I Play the digitized footage in FC it appears to be in fast forward... Not sure if this is a Frame Rate Issue???
I don't understand. Did the captured clips playback fine in fcp last night? How did you digitize them? You need to either use the correct capture preset in fcp or modify an existing preset. If you're using another piece of software to capture, you gotta let us know this info.

Want to change frame rate, help, please !!
hi all,
i want to know whether, jmf does provide any support for changing the frame rate ? is there any ways by which one can change the framerate, of a live captured video ?
i came across one class "FrameRateControl" in jmf, tried it, but wasn't successful in changing the frame rate. plz help me guys.
if u have came across, when doing live capturing using jmstudio, we can change the frame rate. can we do that in our programs tooo.
please someone, wew64, watergad.......... help me out..........,
thanks for ur help.
niraj.the code is here and it is working on windows, but the framerate could not be changed on linux. it keeps saying rcFormat is null on linux. Then I try to change the framerate with JMStudio, it doest not make any difference as well, it seems keep playing the video with preferred frame rate as well. Any ideas?

CS6 imports file at incorrect frame rate
Hi all,
Exported recordings from Screenflow and using Premiere Pro CS6 to edit them.
We have two screen captures from Screenflow made on the same day. We exported both with the same settings into .mov files.
part-1.mov imports correctly at 25 fps.
part-2.mov imports incorrectly at 2.5 fps. ???
We tried the following without remedy:
- restarting Premiere Pro
- re-exporting part-2 in Screenflow
- opening the exported file in QuickTime and export it again using QuickTime, as QuickTime sees the frame rate correctly
Still no luck. We're stuck.
part-2 does look choppier in Premiere than it does in Screenflow. It is visibly dropping frames.
To add more frustration, Premiere imports the file with the correct duration, about 1:03:31. So if we mess around with the frame rate in Clip > Modify > Interpret Footage..., it speeds up the clip and has the wrong duration.
Does anyone know what's happening? Is there a way to modify the frame rate of a clip without affecting its duration?
Thanks,

Hi experts,
I am working with JMF to capture a video source and display it in a JInternalFrame.
I set the frame rate to 30fps, but when running the program I only have 1fps. If I set the LightWeightRenderer of the Manager to false, then I have 16fps (not the 30fps requested).
If I use JMStudio I get the 30fps.
Do you have any idea of what's going wrong ??
Your ideas are welcome.
MatthieuThanks for your answers.
In fact, I am capturing a video source coming from an echograph with a Miro PCTV video card (bt848).
My computer runs with WinXP on a PentiumIII 450Mhz, 256Mo of RAM, and a NVidia GeForce 2 GTS with 32Mo of RAM.
I obtained the following results:
-> Using RGB, 640x480, 24bits, 30fps :the real frame rate is 3-4 fps.
-> Using YUV, 640x480, 30fps: the frame rate reaches 15 fps.
-> Using JMStudio I always get 30fps.
This frame rate is given by the video player.
I think that the problem is not linked to the hardware configuration but in the way the video is displayed in the application.
Indeed, I don't anderstand why JMstudio is able to give 30fps and my application only a few fps.
The main difference is that I display the video in a JInternalFrame and in a Frame. But even if I supress the Manager.LightWeightRenderer support results are a little better but I never reach the 30fps.
To build the video renderer I have used the MDIApp.java and JMFrame.java files given by Sun.
My question is what can do the difference? How can the Sun code be so performant ?
If you want more details on my code, I can put some piece of code on the forum.
Thanks to find a solution because I am going to go crazy !!!! -
Setting jmf bit rate/ frame rate
Hi!!
I'm with some problems configuring my video settings.
Where should I go to set the frame rate od my video streaming?
I'm using H263 format, and the frame rate is variable and I want to set it for a lower value so that my video streaming can be more "fluid".
Should I go to Control Panel of the Windows and change there at Multimedia codecs?
Regards from PortugalHere You have sample how to specify frame rate (in this exampke - 10f). I use here data from video caprure and create processor with ProcessorModel. Then I send it by network (RAW_RTP - in this dimentions it id H263)
VideoFormat vf = null;
Dimension size = new Dimension(176, 144);
vf = new VideoFormat("RGB", size, Format.NOT_SPECIFIED, null, 10f);
Format [] formats = new Format[] { vf };
ContentDescriptor cd = new ContentDescriptor(ContentDescriptor.RAW_RTP);
ProcessorModel proc_mod = new ProcessorModel(dsCapt, formats, cd);
dsCapt is DataSource from my capture device.
for details look: JVidCap file from : http://java.sun.com/products/java-media/jmf/2.1.1/solutions/JVidCap.html -
Can't set frame rate on animated GIF PSE8 on Mac
When saving an animated GIF in Elements 8 (running on Mac OSX 10.6 Snow Leopard) I can't modify the frame rate. It is set at the default .2 delay and can't be modified. Anyone know of a fix for this?
Thanks.Thanks Barbara... I have used that very workaround already - but was hoping there was a solution so I could just do it in the app designed for this! So unfortunate that Adobe knows about this bug and hasn't fixed it!
