Hi!
The GoPro Hero3 has 1440 and 2K7 resolution.
I cant open these files with Virtualdub.
Is there a limit or have I just missed a parameter somewhere?

greetings from Roger

Disable directx use for virtualdub display panes after able to view the video in any display pane

Un-Select Preferences - Display - Use DirectX for display panes Check that no other directx option is still enable in the same preference window

Unable to open the video with virtualdub and after trying other filters to load the video with. Maybe you could load and decode with using avisynth v206alpha4 version with its separate directshowsource update could load the video as is ? http://sourceforge.net/projects/avisynth2/...Alpha_Releases/

If able to open a avisynth (avs) script in virtualdub and unable to work with the video. Try using with stackvertical and stackhorizontal commands to stich the video parts to a whole video

Or until virtualdub and avisynth has support for these UltraHD videos try other softwares such as avidemux. Try with direct file open and with the avisynth (avs) script.

Thanks vdub, I have never used AviSynth but I guess it is time to learn.
I'll try your tips when I find some spare time and report back to the forum afterwards.

Maybe different for UltraHD and depends on the codec you have already installed for decoding UltraHD video

Copy the below to a text file and rename it AnyFileName.avs. Drop it onto virtualdub or any software that can use avisynth avs script to load media files. Maybe sometimes need to use file load with a video filter selected to load the video. If a video loads but only has a black screen no video decoded seen when advance the time-line (navigate the video) as can happen also with virtualdub

DirectShowSource("Drive:\UltraHDVideo.ext", fps=UltaHDVideoFPS, Audio=Yes)

Other options maybe needed for UltraHD to load video with the above basic directshow file load avisynth avs script
