convert to Image Sequence doesn't work in FullHD-Projects

[Jakob Lettenbichler]

when converting a big (e.g.FullHD) Videoclip in an FullHD-Project into an Image Sequence (right-click on the clip), the program produces 1MB-.PNG-Files which can't be opened (Error: not enough compressed data, this comes, when opening the .PNG-Files in Linux). But when your are using a smaller project-resolution (e.g. NTSC or PAL), the Image sequence of the same Videoclip is working fine (as long as the picture-size stays smaller than 1MB). I suspect that the converter has a limit for the image-size of 1MB. When there would be a bigger file, then the converting process gets aborted and the next frame will be done before finishing the last one.

1. Ubuntu 9.10
2. PPA
3. Openshot 1.1.1

Hi,
This is really to big (the second link) because i have done an error for looking the picture FullHD-project-Resolution.(the message is that the picture can be display because there are some errors). I have had never this.same here.
Thanks to report this bug here too.

I've rechecked this after a software Update. Problem is still here. (to reproduce the Bug, please open a new project in FullHD-Resolution, import the Videofile and then convert to image-sequence. After this you can find the broken Files in the project-directory)

Ubuntu 10.4
Openshot 1.1.3
Installation via Ubuntu Software-center
I also upgraded Melt to 0.5.4-1 (former Version was 0.4.?)

I'm seeing the same artifact.
It appears that the truncated file sizes vary in length around a megabyte.
Note the file sizes in the attached screen grab. This sequence is from a 720p mp4 file.

Other than this... I love OpenShot.
