[Tutor] video watermark
Hi everyone. Can someone suggest a python module so that it would be able to do a video processing and adding watermark in video? -- If it's not loud, it doesn't work! -- Blank Reg, from Max Headroom ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Once I had to blur the part of the viewing area of a screencast which showed some confident CAD model. First, I exported the video as sequence of images with virtualdub. The result was something like 3000 *.bmp files on my harddrive. Then I created a little python script using PIL (http://www.pythonware.com/products/pil/). That script processed the files file by file, so no worries about huge movie files and memory. Finally, I've merged the new images with virtual dub. It all worked very well. Otherwise I'm not aware of any video processing library in Python. Also, there're filters for virtualdub to add watermarks to a movie. That might be the easiest way to get your results.

Re: [Tutor] Video file metadata? (MP4/WMV)
Hi Allen. I don't know of a Python module but I believe that ffmpeg will do what you want. Inside ShowMeDo I start it using os.spawnv and I use Python to do some processing on ffmpeg's output. We use it to transcode incoming AVI/MOVs to .FLV files. This would be more involved than just using a module. I've never looked at ffmpeg's handling of metadata but looking at the help I see: [EMAIL PROTECTED]:~$ ffmpeg ... -title string set the title -timestamp time set the timestamp -author string set the author -copyright string set the copyright -comment string set the comment -album string set the album ... which might be what you're after? You should also be able to use ffmpeg for automated conversion to MP4. The only drawback is that ffmpeg might not understand the most recent WMV formats (WMV9 if memory serves) as Microsoft won't open the spec. HTH, Ian.

However, the correct information is correctly encoded in the file name.. i.e. title-author-date.wmv Seems like the a great job for Python. :) Also, I am about to convert these fiiles to MP4 for use on an iPod. The video software I am using will, I think, transfer the metadata from the WMV to the new MP4 files. So, two questions: 1) Does these exist a python module I can use to programatically edit the metadata in MP4 files? 2) Failing that, is there a python module I can use to edit the metadata in the WMV files?

Re: [Tutor] Video file metadata? (MP4/WMV)
Don't think so. Do you have any cmdline tool to update the meta data? Alternativly you can naturally embed Win32 components and control them with Python, but I'm not a Windows guy.

Hi Eric, You probably want to ask this on a newsgroup like comp.lang.python; I don't think many of us here are familiar with PVR stuff. There are such systems written in Python. For example, Freevo: http://freevo.sourceforge.net/ but the subject is so specialized that Python-tutor probably won't be too effective. A larger audience like comp.lang.python might be able to give you better guidance. Good luck! ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
