Can't export in flash format

[jweb]

I'm trying to create a flash file for internet use.
The original file is Quicktime H.264....When I encode the video the progress bar jumps right to finished.

Here is what the progress report says:

Any answers or suggestions would be great.

Thanks in advance.

I don't remember ever seeing that one.
I tried to replicate your situation by creating a .mov (H.264/PCM) and converting that to .flv, but I couldn't get that error to appear.
Strange one.

I am running into a similar problem when trying to encode Flash Video. Going from .mov (h264) to .flv. The progress bar goes to "Finished" immediately. A file is created, however it is 0kb. When I click on the info icon in the Progress window, I get the following msg:

Codec type mismatch for mapping #0.0 -> #0.0

If anyone has any advice or suggestions, I would greatly appreciate it!!!
Thank you!!

Codec type mismatch for mapping #0.0 -> #0.0

Normally I would suggest the "Invert mapping" checkbox in the Audio tab for this error,
but there seems to be an issue with the combination of Invert mapping and encoding to FLV.

So, I suggest doing the Invert mapping "by hand" in QuickTime Pro. Open your .mov in QTP. Show Movie Properties. Extract the soundtrack. Delete the soundtrack. Switch to the extracted Untitled soundtrack window. Select all. Copy (to clipboard). Switch back to the .mov window. Select all. Add (from clipboard) to movie. Save as self-contained .mov.
The stream mapping is now reversed and should convert fine.

Case,

The "invert mapping 'by hand'" freekin' did the trick. I too was struggling to make a FLV file. Thank you so much.

By the way, what is the recommended bitrate for FLV or Flash Video. The preset for FFmpegx is 200kb but it made such a tiny file...like 150k. I experimented with 400 - 600kb and it makes such a difference and the file size seems to be okay. 2.4 mb for a 30 second commercial 320 x 240, 29.97 frames a second.

Cheers,
Justin

Thanks Case, but I'm still having a problem. When I paste the track in QT back I end up with a movie twice the length with sound only at the first half and movie with no sound at the second. I think I'm following your instruction to the letter but I'm obviously doing something wrong... or could it be anything to doing with working on a Mac?

Mak,
Don't 'Paste', but 'Add to Movie', (while having the whole video selected), so that the tracks occupy the same timeline.

[makman]

Did it! Thanks Case.

I need to test this as well.

Question about bitrate etc. I have recorded a filmclip with my CamCorder (Sony HDR-SR12E) in FullHD (1080i) and would like to make sure to get a FLASH file (FLV) that has really good quality. I know getting the same as FullHD might not be duable, but I do not want to make TOO much image quality loss.

Anyone have suggestions to how I should set my settings?

Sincerely,
Andreas

I would like to make sure to get a FLASH file (FLV) that has really good quality.

"Eye of the beholder." You want to get the file as small as possible (because of downloads) and good quality (making a file bigger). Opposing characteristics. You'll have to find your own optimum. Things to consider:
- Can you host the file yourself or do you depend on a 3rd party hosting service that has restrictions on your FLV file?
- How much are you prepared to scale down? 320x240?
- Convert a series of short test clips at various settings (bitrates) to see what works for you.

hi, is there a more user friendly way to do this by now?
or is there still only the 'by hand' thing?

thanks

Hi,
I'll second tomerm.
I'm having the same problem and was wondering if a more user-friendly approach has been arrived at?

unfortunately i am not the creator of the movie files i have to convert. so i cannot go back into quicktime and edit them files by hand.

any suggestions would be wonderful. this is a nice tool, but i only need it to convert to flv. so i might have to look elsewhere if the "manual" method described above is the only solution.

You don't have to be the creator of the movie files to reverse the streams manually in QuickTime Pro.

Hi Case:

This all worked great for me too - thanks. Only now, I have another issue. The first few seconds of the video is a photoshop graphic I imported into iMovie then there is regular NTSC video after that. I went through the "Invert mapping by hand" thing and it all plays great in the quicktime player, but when the conversion is complete, the few seconds of the graphic is gone! I even tried to go back to imovie and add a sound track under the graphic thinking maybe it was an audio sync thing, but that didn't work either... Any suggestions would be much appreciated, and thanks for your great help here on this board.

Sorry, I was unclear when I said "when the conversion is complete" I meant the conversion from the .mov file to .flv using ffmpegX.

I'm not an iMovie user, but perhaps you can try to save or export differently (DV stream?), so that the intermediate file has the graphic as part of the video, and not as an inserted graphic in a .mov file.

Your FLV file is converted fine, but does not have meta data yet. Meta data will help player software to know more about the file, such as duration and remaining play time.
1/ Have you installed flvtool2, the binary that updates FLV files with meta data? Without it, an 'error'-message in the log is expected.
2/ ffmpegX activates flvtool2 using the ruby scripting language. Unfortunately, the location of the Mac OS-installed ruby binary is not the same for every version of Mac OS X. You may need to patch ffmpegX to fix that.
