This has some prior discussions so let's keep it short.
No.
Hi,
I am wondering if it is possible to take a video that's been optimized for a small screen such as a IPod or Android, formatted in an mp4 container, and make it larger, say for viewing on a PC or something similar? I know if I play the small file on the PC, its obvious the quality is terrible, but is there a way to actually convert the small file to a larger size therein improving its quality? If so, what type of software application would be optimal for that?
I use Linux so I'm looking for a program that might be able to do such a thing so please don't only name Windows-specific software but just generalize the category. I am familiar with transcoding software such as Handbrake and DVD Rippers but its kinda the opposite I am looking for.
Any ideas or suggestions?
