Hi,
I have a suggestion for improvement for the drawtext filter.
If the text is read from a file, it must be in UTF-8 format. In Windows,
many text editors (including Notepad) insert a 3-byte "Byte order mark"
at the beginning of the file. This is described here:

Hi,
I do not know much about windows but I remember many times using named pipes
tripped people up, as they are not simple fifo pipes as in linux, but a more
transactional and object-oriented construct. Not sure if it’s any help but look
into the different types of pipes you can create and how
Does FFMPEG encoding the video? Because if encode one video twice with same
arguments, it's giving the exactly same file. For example, if rendering on
Adobe Premiere 2 times same file it gives 2 unique video files. Is it
possible to make Unique videos after encoding by ffmpeg? If yes, than how?
Hey,
> Does FFMPEG encoding the video?
I don’t know, is it? Show us the command you typed in and the output.

To Whom It May Concern:
I have been trying to get a direct import from a Sony DSR-45 DV Deck. Using OS
X Final Cut Pro hot annoying with various issues.
Does anyone have suggestions or a method for doing this better? I have 500-600
more DV tapes to ingest.
Using this command brings in a 12GB

Actually, he wanted to slow down the video so you probably meant the reciprocal
of this, 2*PTS and atempo 1/2

Hi,
I want to slow down a mp4 video from 30 to 15 fps, so it has twice duration.
Also I want the audio stream to to transform so that the audio is transformed
to the natural frequency, i.e. the speach is in half speed.
How can I do this?

Same version of ffmpeg works on other computers? I suppose you could
drill into the code and try and see what it's doing with pipes...

Hello there
I have been experiencing drop frames during calculation of framemd5
checksums for a bunch of DPX files.
The command:
*ffmpeg -start_number 86400 -i finalDPX_forDCP\Respire%08d.dpx -f framemd5
original_md5_2.txt*
The result:
frame=20837 fps=5.2 q=-0.0 Lsize=1628kB
