We never tried that - instead we would create a batch file to call makebif.bat for each filename we needed bif files for. Something like Call makebif.bat "file1" Call makebif.bat "file2" Call makebif.bat "file3" Call makebif.bat "file4" Call makebif.bat "file5"
It's probably related to your inability to specify the exact framerate as an integer. If you're saying it's 30fps and it's 24fps then it would be out of sync. If you create the bif file by hand instead of relying on the batch file to make it for you, and it's in sync, then that might be the big problem for your solution.
Open virtualdub ( veedub64.exe ) Open your video file Cllick Video/Filters Add Resize Click Absolute Click disabled Aspect Ratio Set the image to 320 x 240 Click OK Click OK Click Video/Framerate It tells you the current framerate, but go to the bottom for "Decimate by" and enter the framerate *10 as an integer/round if necessary to 240 for 23.976 etc etc Click OK Select File and Export / Image Sequence select the directory to save the images and click OK.
When it's done, run biftool.exe from a command line, -t 10000 means it will set it for one image every 10 seconds, which matches your decimate by 10* framerate biftool -t 10000 c:\foldername
That's all the batch file does. With proper operation if you rounded up from 23.97 to 24, then 23.97 * 60 seconds * 60 minutes * 2 hours = 172584 24 * 60 seconds * 60 minutes * 2 hours = 172800
If you do the math then your very last frame for the bif file in the rounded result will be 216 frames later than where it should be, which is within 8 seconds of film, but since the interval is 10 seconds it's barely even an issue.
Any ideas for creating bifs on a linux server? I currently use FFMPEG and it takes a VERY long time, though to be fair, the system resources are super low, 2 cores and 2GB of RAM. I've been trying to research if increasing the system resources would help but the answers are all for converting/trans-coding so i'm not sure if it would apply to chopping images and generating a bif.
If I should keep using FFMPEG, does anybody have an idea on boosting speed. Or is there a recommendation for other tools to creating the bifs on a linux system?
